    LAURA KOS ET AL. v. LAWRENCE +
    MEMORIAL HOSPITAL ET AL.
    (SC 20256)
    Robinson, C. J., and Palmer, McDonald, D’Auria,
    Mullins, Kahn and Ecker, Js.
    Syllabus
    The plaintiffs, K and her husband, sought to recover damages from the
    defendants, G, a physician, and G’s medical practice, for personal injuries
    that K had suffered in connection with G’s alleged negligence in, inter
    alia, failing to perform a proper and adequate episiotomy repair after
    the birth of the plaintiffs’ son. G had performed an episiotomy to facilitate
    the delivery of the plaintiffs’ son. After the delivery, G evaluated K
    and diagnosed her with a third degree episiotomy extension, which G
    repaired. After the repair was completed, G performed a digital examina-
    tion of K’s rectum and determined that there were no breaks or defects
    in K’s rectal mucosa. Although an exam of K’s perineum the day after
    the delivery indicated no issues with the repair, K subsequently reported
    complications, including pain, an infection, and a rectovaginal fistula
    that required surgery. At trial, the plaintiffs’ expert witness, Y, testified
    that the standard of care requires that a physician, after performing
    an episiotomy, correctly diagnose and repair the episiotomy and any
    extension thereof, which must involve a thorough rectal examination
    before the repair. Y also testified that G failed to satisfy the standard
    of care because, in failing to conduct a proper examination, G misdiag-
    nosed and repaired the episiotomy extension as a third degree rather
    than a fourth degree extension, and that this error led to the rectovaginal
    fistula. According to the defendants’ expert, L, G complied with the
    standard of care, which required that the rectal exam be performed
    after rather than before the episiotomy repair. L also testified that G had
    correctly diagnosed and repaired a third degree episiotomy extension.
    Finally, another expert witness presented by the defendants testified
    that K’s rectovaginal fistula was not caused by an unrepaired fourth
    degree episiotomy extension but, rather, an infection. The trial court
    instructed the jury that the plaintiffs had alleged that G breached the
    standard of care by failing to identify a fourth degree episiotomy exten-
    sion and by failing to properly examine and adequately repair a fourth
    degree extension. The court also charged the jury on the acceptable
    alternatives doctrine concerning the standard of care for conducting
    the digital rectal examination. The jury returned a verdict in favor of
    the defendants, finding that the plaintiffs had sustained their burden of
    establishing the standard of care but failed to sustain their burden of
    establishing that G breached the standard of care. On appeal, the plain-
    tiffs claimed, inter alia, that the trial court improperly instructed the
    jury by including a charge on the acceptable alternatives doctrine and
    limiting their allegations regarding breach of the standard of care. Held:
    1. Although the trial court improperly instructed the jury on the acceptable
    alternatives doctrine, that charge was harmless under the circumstances
    of the present case, and this court declined the plaintiffs’ request to
    abolish that doctrine: the inclusion of an acceptable alternatives charge
    in the court’s instructions was improper when the testimony of both
    parties’ experts failed to establish that conducting a rectal examination
    either before or after the episiotomy repair was an acceptable method
    of diagnosing the particular degree of the extension, as Y testified that
    the examination should be performed before the repair, whereas L
    testified that it should be performed after the repair and that an examina-
    tion prior to the repair generally was not an approved method of diagnos-
    ing the degree of the extension, and when the parties argued during
    summation that there was only one proper method of examination to
    properly diagnose the degree of the extension and neither party argued
    that G chose between two acceptable alternatives in performing the
    examination after the repair; nevertheless, the trial court’s improper
    inclusion of an acceptable alternatives charge in its jury instructions
    was harmless, as that error would not have confused or misled the jury
    because, whether G properly performed the rectal examination mattered
    only if there was a fourth degree episiotomy extension, and the jury
    necessarily found that there was no fourth degree extension in finding
    that G did not breach the standard of care, and the improper charge
    did not otherwise interfere with the jury’s determination regarding the
    credibility of the experts or exculpate G by suggesting that both methods
    of examination were accepted within the medical community; moreover,
    this court declined the plaintiffs’ request to abolish the acceptable alter-
    natives doctrine, as it determined that this case, in which the doctrine
    was held to be inapplicable, was not the appropriate case for deciding
    whether the doctrine should be abolished.
    2. The trial court’s supplemental instruction, in response to the jury’s request
    for clarification, that the plaintiffs’ expert, Y, testified that an internal
    rectal examination must be performed prior to an episiotomy repair as
    a required component of the standard of care, did not improperly limit
    the plaintiffs’ allegations regarding breach of the standard of care: the
    trial court’s response to the jury’s request for clarification was consistent
    with the evidence presented at trial and how the plaintiffs’ counsel had
    argued the case to the jury, and nothing in the supplemental instruction
    negated the plaintiffs’ allegation that, by breaching the standard of care
    in failing to perform an examination before the repair, G failed to diag-
    nose and repair a fourth degree extension; moreover, in reading the
    trial court’s charge as a whole, this court determined that it was clear
    that the trial court instructed the jury that the plaintiffs’ allegations
    regarding breach of the standard of care included insufficient inspection,
    diagnosis and repair of a fourth degree extension and, accordingly,
    would not have confused and misled the jury into determining that,
    even if a fourth degree extension had existed, the defendant did not
    breach the standard of care; furthermore, to the extent that the court’s
    supplemental instruction did limit the plaintiffs’ allegations, a second
    supplemental instruction by the court, which contained language nearly
    identical to the language the plaintiffs sought to include in the first
    supplemental instruction, cured any error in the first supplemental
    instruction.
    Argued October 15, 2019—officially released March 10, 2020
    Procedural History
    Action to recover damages for, inter alia, medical
    malpractice, brought to the Superior Court in the judi-
    cial district of New London, where the action was with-
    drawn as to the named defendant et al.; thereafter, the
    case was tried to the jury before Bates, J.; verdict for
    the defendant Elisa Marie Girard et al.; subsequently,
    the court denied the plaintiffs’ motion to set aside the
    verdict and rendered judgment in accordance with the
    verdict, from which the plaintiffs appealed. Affirmed.
    Alinor C. Sterling, with whom, on the brief, was
    Kathleen L. Nastri, for the appellants (plaintiffs).
    Stuart C. Johnson, with whom were M. Karen Noble
    and, on the brief, Michael R. McPherson, for the appel-
    lees (defendant Elisa Marie Girard et al.).
    Opinion
    D’AURIA, J. In this medical malpractice case, the
    plaintiffs, Laura Kos and Michael Kos,1 appeal following
    the trial court’s denial of their motion to set aside the
    jury’s verdict in favor of the defendants Elisa Marie
    Girard and Physicians for Women’s Health, LLC,2 on
    the ground that the trial court improperly instructed
    the jury by (1) including a charge on the acceptable
    alternatives doctrine, and (2) limiting their allegations
    regarding Girard’s breach of the standard of care. Alter-
    natively, they request that this court abolish the accept-
    able alternatives doctrine. Although we agree with the
    plaintiffs that the trial court improperly instructed the
    jury on the doctrine of acceptable alternatives, because
    we find this error harmless and because we decline to
    take this opportunity to abolish the acceptable alterna-
    tives doctrine, we affirm the judgment of the trial court.
    Reading the record, as we must, in the light most
    favorable to sustaining the verdict for the defendants,
    reveals that the jury reasonably could have found that,
    on August 19, 2011, the plaintiff gave birth to a son at
    Lawrence + Memorial Hospital in New London. Girard,
    who was employed by Physicians for Women’s Health,
    LLC, in Groton, was the physician on call at the time.
    During labor, after the plaintiff had been pushing for
    approximately two hours, Girard decided to use a vac-
    uum to assist in the delivery. When Girard’s use of the
    vacuum was unsuccessful, Girard performed a median
    episiotomy—a surgical cut made in the perineum (the
    muscular area between the vagina and the anus) from
    the vagina toward the rectum—to reduce the tight band
    of tissue around the baby’s head that restricted his
    movements. Girard testified that this episiotomy was
    the equivalent of a second degree laceration. See foot-
    note 3 of this opinion.
    After performing the episiotomy, Girard successfully
    delivered the plaintiffs’ son. Because Girard had used
    a vacuum and had performed an episiotomy, the plain-
    tiff was at risk of sustaining an extension of the episiot-
    omy, requiring Girard to inspect the plaintiff’s vaginal
    tissue. An extension of the episiotomy is diagnosed by
    degree, with first degree involving the least amount of
    tissue trauma and fourth degree involving the most
    severe trauma.3
    In conducting the inspection, Girard first inspected
    the plaintiff’s cervix and surrounding tissue, looking for
    tears, bleeding, or hematomas. Upon finding no issues,
    Girard then used a laparotomy pad (gauze) to block
    any bleeding from the uterus, which usually bleeds after
    a vaginal birth, and to have an unobstructed view of
    the lower vagina, perineal tissue, and rectum. Girard
    focused on the area of the episiotomy, inspecting for
    an extension. Through visual inspection and physical
    manipulation by gloved hands, Girard determined that
    the episiotomy had extended through the plaintiff’s anal
    sphincter, which was separated. Because of the injury
    to the anal sphincter, Girard was able to see the outer
    aspects of the rectal mucosa and to feel that it was
    intact. Because the rectal mucosa was intact but the
    anal sphincter was torn, Girard diagnosed the plaintiff
    with a third degree extension of the episiotomy, which
    she then repaired. See footnote 3 of this opinion.
    After repairing the tear, Girard inspected the repair
    and conducted a digital rectal exam. Although Girard
    had examined the outer aspect of the rectal mucosa
    before the repair, she wanted to feel the internal side
    to ensure that the perineal body and sphincter muscles
    were adequately repaired, that bulk and tone were
    appropriate, that thickness between the tissue was
    appropriate, and that there were no breaks or defects.
    There was no indication of a tear or defect in the plain-
    tiff’s rectal mucosa. Girard did not conduct a digital
    rectal exam before the repair because she was trained
    to perform the exam after the repair to prevent contami-
    nation to the open wound.
    The day after the delivery, prior to the plaintiff’s dis-
    charge from the hospital, the repair of the perineum
    was inspected and found to be intact. The plaintiff’s
    medical records do not indicate that, as of that time,
    she was complaining of discharging stool or flatus (gas)
    from her vagina. In a follow-up appointment, however,
    on September 1, 2011, she reported vaginal discomfort
    and stool coming out of her vagina. An opening in the
    episiotomy site of less than half a centimeter was noted,
    along with discharge that looked and smelled like stool.
    In a subsequent follow-up appointment with another
    physician, although the plaintiff did not bring any medi-
    cal records with her, she reported that she had sus-
    tained a fourth degree extension of the episiotomy dur-
    ing birth and a rectovaginal fistula—an opening
    between her vagina and rectum. At that time, she com-
    plained of perineal pain and was concerned about hav-
    ing developed an abscess. An examination did not estab-
    lish the existence of a rectovaginal fistula, but the
    plaintiff’s symptoms—including the discharge and the
    smell—were consistent with a rectovaginal fistula. The
    opening in the vagina that previously had been noted
    was not detected. Additionally, the examination estab-
    lished that the plaintiff suffered from a sphincter sepa-
    ration.
    The plaintiff later reported concerns that she had an
    infection, complaining of drainage from a hole in her
    perineum. She also complained of pain and redness,
    which, along with the drainage, were signs of infection.
    No rectovaginal fistula was detected. Upon further
    examination, Richard Bercik, an urogynecologist, noted
    that the episiotomy repair was intact but discovered
    a small rectovaginal fistula just inside the posterior
    fourchette and sphincter complex. John Gebhart, a uro-
    gynecologist at the Mayo Clinic, also noted the exis-
    tence of the rectovaginal fistula, as well as granulation
    tissue (a sign of infection), and two other openings in
    the vaginal wall, although neither led to the rectum.
    The size of the rectovaginal fistula was described as ‘‘a
    very small hole . . . .’’ The plaintiff thereafter under-
    went surgery to repair the rectovaginal fistula and the
    sphincter separation.
    The plaintiffs later filed this medical malpractice
    case. In counts one and three of the operative complaint
    the plaintiff alleged claims of medical malpractice
    against the defendants. In counts two and four, the
    plaintiffs alleged claims of loss of consortium against
    the defendants on behalf of Michael Kos. Specifically,
    they alleged that Girard was negligent in that she had
    failed to identify a fourth degree extension of the
    median episiotomy, failed to perform a proper and ade-
    quate episiotomy repair, and failed to properly examine
    the episiotomy repair after it was complete. They
    alleged that Physicians for Women’s Health, LLC,
    Girard’s employer, was vicariously liable for Girard’s
    negligence. They further alleged that, as a result of
    Girard’s negligence, the plaintiff sustained serious injur-
    ies, including a rectovaginal fistula and an anal sphinc-
    ter defect.
    At trial, the plaintiffs presented the plaintiff’s medical
    records, testimony from physicians who treated her
    after the birth of her son, and expert testimony from
    Brett C. Young, a maternal fetal medicine specialist,
    obstetrician and gynecologist. The defendants pre-
    sented expert testimony from Frank Wen-Yung Ling,
    an obstetrician and gynecologist, as to the standard of
    care, and from Michael K. Flynn, a urogynecologist, as
    to causation.
    At the close of evidence, the defendants requested
    that the trial court include a charge on the acceptable
    alternatives doctrine concerning the standard of care
    for conducting the digital rectal exam. The plaintiffs
    objected, but the trial court overruled the objection and
    gave the requested charge. After requesting clarification
    of the court’s instructions; see part I A of this opinion;
    the jury reached a verdict in the defendants’ favor.
    According to the jury interrogatories, the jury found
    that the plaintiffs had sustained their burden of estab-
    lishing the standard of care but had failed to sustain
    their burden of establishing that Girard had breached
    the standard of care. The plaintiffs then filed a motion
    to set aside the verdict, arguing that the jury had been
    improperly instructed on the doctrine of acceptable
    alternatives. The trial court denied the motion. The
    plaintiffs appealed to the Appellate Court, and the
    appeal was transferred to this court pursuant to General
    Statutes § 51-199 (c) and Practice Book § 65-1. Addi-
    tional facts will be set forth as required.
    I
    The plaintiffs first claim that the trial court improp-
    erly instructed the jury by including a charge on the
    acceptable alternatives doctrine because no evidence
    supported the charge. The plaintiffs argue that, to give
    the instruction, an expert had to testify that there was
    more than one proper technique for conducting the
    digital rectal exam, and that the experts’ dueling opin-
    ions about when to conduct the exam—before or after
    the episiotomy repair—was not the equivalent of testi-
    mony that either option was an acceptable alternative.4
    The plaintiffs further contend that this improper charge
    was harmful because it was inapplicable and its inclu-
    sion interfered with the jury’s assessment of credibility
    by exculpating the defendants and implying that
    Girard’s actions were reasonable. Alternatively, the
    plaintiffs ask this court to abolish the acceptable alter-
    natives doctrine.
    The defendants respond that the acceptable alterna-
    tives charge was proper because there was evidence
    that there was more than one approved technique
    within the medical community. They contend that the
    evidence supports the charge as long as there is expert
    testimony supporting more than one proper method,
    even if an expert does not specifically state that both
    methods are acceptable. Alternatively, the defendants
    argue that any impropriety was harmless because it did
    not affect the central issue regarding liability—whether
    a third or fourth degree extension of the episiotomy
    occurred. Moreover, the defendants contest the plain-
    tiffs’ argument that the charge exculpated the defen-
    dants or interfered with the jury’s credibility determi-
    nation.
    We agree with the plaintiffs that the acceptable alter-
    natives charge was improper but agree with the defen-
    dants that it was harmless. Because we determine that
    any error was harmless, we decline to take this opportu-
    nity to abolish the acceptable alternatives doctrine.
    A
    The following additional facts and procedural history
    are necessary to our review of this claim. At trial, in
    addition to the plaintiff’s medical records and testimony
    from her treating physicians, the plaintiffs offered
    Young’s expert testimony. Young testified that the stan-
    dard of care required that a doctor, after performing
    an episiotomy, must correctly diagnose and repair the
    episiotomy and any extension thereof. To do so, Young
    testified, a doctor must conduct a thorough examina-
    tion before repairing the episiotomy and any extension.
    This includes a digital rectal exam, which involves plac-
    ing a gloved finger into the anus and lifting up toward
    the vagina to identify whether the gloved finger can be
    seen from the vagina, meaning that a hole exists
    between the anus and the vagina. Young testified that
    the digital rectal exam must be conducted before
    repairing the episiotomy because, otherwise, the exten-
    sion will be repaired as a third degree extension, not
    a fourth degree extension, and, once repaired, it is more
    difficult to examine the rectal mucosa because the vagi-
    nal tissue is no longer ‘‘splayed’’ open.
    Young opined that Girard failed to satisfy this stan-
    dard of care ‘‘because she failed to identify a fourth
    degree laceration . . . [which] subsequently had the
    complication of breaking down and opening the sphinc-
    ter . . . causing [the plaintiff to experience] inconti-
    nence and pain.’’ The basis for this opinion was that,
    by failing to conduct a proper exam, Girard misdiag-
    nosed and repaired the episiotomy extension as third
    degree, rather than as fourth degree. Young testified
    that this error caused a rectovaginal fistula, which
    allowed for the passage of fecal matter and gas through
    the anus to the vagina, contaminating and weakening
    the repair of the anal sphincter. Young conceded, how-
    ever, that, if the plaintiff had sustained only a third
    degree episiotomy extension, she had ‘‘no criticism of
    how [Girard] did the repair . . . .’’
    In contrast, Ling testified on behalf of the defendants
    that the standard of care required that a digital rectal
    exam be performed after an episiotomy repair, not
    before, and that Girard had complied with this standard
    of care. Specifically, he testified that, once the perineal
    muscles and anal sphincter tear, the rectal mucosa must
    be carefully inspected to determine whether there is
    a fourth degree extension. He testified that, first, the
    physician must conduct an external inspection using
    gloved hands to spread open the vaginal tissue to look
    at the laceration. Ling testified that a physician should
    be able to make a diagnosis after this visual inspection
    because, once the anal sphincter muscle is separated,
    the tissue will be splayed open so that the physician
    will either see the outside of the rectum (meaning there
    is a third degree extension) or the inside of the rectum
    and the rectal mucosa (meaning there is a fourth degree
    extension). He testified that it is ‘‘almost impossible’’
    not to visually diagnose a fourth degree episiotomy
    extension.
    Only after repairing the extension, according to Ling,
    does a physician then conduct a digital rectal exam,
    feeling for whether the rectal mucosa is intact and
    smooth. He explained that ‘‘[p]utting a gloved finger in
    the rectum before you do the repair is actually frowned
    upon by a lot of folks because of how easy it is to
    make a diagnosis without putting a gloved finger in
    the [rectum] and the fact that doing a gloved finger
    examination of the rectum is not itself innocuous, mean-
    ing there are negative consequences. . . . When you
    do fix it or repair it, it would be compromised by more
    bacteria or more contamination, which could cause a
    breakdown and can cause more problems . . . [like] a
    greater chance of infection or failure of that episiotomy
    [repair]. You might even worsen a problem by creating
    a hole by putting your finger in the rectum.’’ Because
    of these risks, Ling opined, the standard of care does
    not require a rectal exam before the episiotomy repair,
    but, rather, such a procedure ‘‘goe[s] beyond’’ the stan-
    dard of care by ‘‘bring[ing] . . . additional risks
    . . . .’’
    Although Ling testified that Girard had complied with
    the standard of care regarding her inspection technique,
    he further testified that his opinion as to that issue was
    irrelevant because he also opined that Girard correctly
    had diagnosed and repaired a third degree extension.
    In other words, whether a digital rectal exam occurred
    before or after the repair mattered only if there was a
    fourth degree episiotomy extension because this exam
    was not required to diagnose and repair a third degree
    episiotomy extension. Nevertheless, Ling conceded
    that, if the plaintiff had sustained a fourth degree episi-
    otomy extension, Girard would have breached the stan-
    dard of care by diagnosing and repairing it as a third
    degree episiotomy extension, thereby not repairing the
    torn rectal mucosa.5
    As to causation, the defendants offered the testimony
    of Flynn, who opined that the plaintiff’s rectovaginal
    fistula was not caused by an unrepaired fourth degree
    episiotomy extension but, rather, by an infection. More
    specifically, Flynn explained that a fourth degree exten-
    sion and a rectovaginal fistula are separate and distinct
    injuries. A fourth degree extension is an ‘‘acute event’’
    where there has been a tear through the rectum,
    whereas a rectovaginal fistula is a ‘‘chronic condition’’
    of an opening that connects the lumen of the rectum
    and the lumen of the vagina, usually brought about by
    infection. Even without a fourth degree extension, a
    rectovaginal fistula may result after a properly repaired
    third degree extension because the tissue has been
    stretched and compromised.
    Flynn opined that this is what occurred in the present
    case: ‘‘The most likely reason she developed a fistula,
    she got an infection in the perineum and the episiotomy
    repair, a small infection. . . . That drained through the
    posterior fourchette, which is what [was seen at her
    first follow-up appointment]. As soon as that abscess
    drained . . . the infection’s not gone, but that little
    pocket of pus is gone, it closed up. That’s why on subse-
    quent examinations it [was not discovered by any other
    physicians]. But the problem is, you still have that bacte-
    ria, you still have that pocket. . . . That infection
    hasn’t resolved, and as that part closes off on the peri-
    neum, now it’s tracking toward the rectum where you’ve
    got an area of weakened mucosa . . . where an infec-
    tion can tract and it tract[s] right down to the anus
    where it opens up into the anus to create the fistula
    tract.’’ He also opined that the anal sphincter separation
    was not a result of a fourth degree episiotomy extension
    but, rather, occurred because the anal sphincter is a
    muscle that is difficult to repair as the muscle causes
    the sutures to stretch and fail over time.
    Flynn further opined that it was very unlikely that
    an undiagnosed fourth degree extension would have
    caused the plaintiff’s rectovaginal fistula. First, the fis-
    tula did not occur in the area of the episiotomy repair
    but, rather, in the posterior fourchette. Second, if there
    had been a fourth degree laceration, it would have been
    difficult not to diagnose the rectovaginal fistula by
    visual inspection once the sphincter was separated,
    splaying the vagina open. Third, because the hole in
    the rectal mucosa was so small, if it had been present
    right after the delivery, it would have healed on its
    own once the other layers of the laceration had been
    repaired. Fourth, due to the small size of the hole in
    the rectal mucosa, only liquid stool, but not solid stool,
    would have been able to pass through it—contrary to
    the plaintiffs’ allegations. If liquid stool had been pass-
    ing through this hole since the day of delivery, the
    bacteria would have permeated the entire repair, and
    the repair would have opened up completely within two
    to five days. Additionally, the hole would have grown
    in size over time. Instead, the episiotomy repair was
    found to be intact.
    During closing argument, neither party referred to
    the acceptable alternatives doctrine, despite the fact
    that the defendants had requested an acceptable alter-
    natives charge. Rather, both parties argued that there
    was only one proper method of conducting the digital
    rectal exam—the plaintiffs argued that it had to occur
    prior to the repair, and the defendants argued that it
    had to occur after the repair. Moreover, although both
    parties discussed Girard’s inspection technique, both
    argued that the crux of the case came down to whether
    there was a third degree or a fourth degree episiotomy
    extension. The plaintiffs’ counsel described the case as
    follows: ‘‘So, the issue in this case is, was there a fourth
    degree laceration, right? That’s the whole issue.
    Because if it’s there, we know she missed it. . . . Third
    degree is the defendants’ case. . . . Fourth degree is
    the plaintiffs’ case.’’ Similarly, the defendants’ counsel
    summarized the case as ‘‘revolv[ing] around [whether
    there was] a third degree laceration that was properly
    repaired or a fourth degree laceration . . . .’’
    The trial court then instructed the jury that the plain-
    tiffs had alleged that Girard breached the standard of
    care by failing to identify a fourth degree extension
    of the median episiotomy, and by failing to properly
    examine and to adequately repair a fourth degree exten-
    sion. The trial court also charged the jury on the accept-
    able alternatives doctrine.6
    After being instructed, the jury sought clarification
    as to whether it could ‘‘use the total testimony of all
    witnesses to ascertain the plaintiffs’ definition of [the]
    standard of care or only Dr. Young’s testimony . . . .’’
    The trial court responded by instructing the jury that
    it was ‘‘permitted to look at all of the evidence, including
    testimony, to determine the standard of care, and it is
    your obligation to determine the standard of care.’’ The
    trial court then reread the standard charge on medical
    malpractice and the charge on reasonable alternatives.
    The plaintiffs’ counsel again objected to the inclusion
    of the reasonable alternatives charge.

    This court addressed the propriety of an acceptable
    alternatives instruction in Wasfi v. Chaddha, 
    218 Conn. 200
    , 
    588 A.2d 204
    (1991). In Wasfi, a medical malprac-
    tice case, the central issue was whether a computerized
    axial tomography (CAT) scan should have been ordered
    before or after attempting to treat the plaintiff with
    carbogen inhalation therapy. 
    Id., 202–203. ‘‘At
    the trial,
    experts on both sides testified concerning, inter alia,
    the propriety of [the defendant physician’s] prescription
    of carbogen [inhalation] therapy prior to ordering a
    CAT scan. . . . [The physician’s] counsel elicited
    expert testimony to the effect that the timing of the
    CAT scan—before . . . or after carbogen [inhalation]
    therapy—was a matter of professional opinion as to
    which physicians differed.’’ 
    Id., 203. On
    the basis of this
    testimony, this court held that the trial court properly
    instructed the jury on the acceptable alternatives doc-
    trine, which we described as ‘‘the settled principle that
    where the treatment or procedure is one of choice
    among competent physicians, a physician cannot be
    held guilty of malpractice in selecting the one which,
    according to his best judgment, is best suited to the
    patient’s needs.’’ (Internal quotation marks omitted.)
    
    Id., 208. Unlike
    the present case, Wasfi did not involve two
    experts with dueling opinions regarding the proper pro-
    cedure, with neither expert agreeing that the alternative
    procedure was acceptable in the medical community.
    This court in Wasfi, therefore, did not address whether
    the acceptable alternatives charge could be supported
    by experts with differing opinions. Rather, in Wasfi,
    an expert specifically testified that both procedures—
    ordering the CAT scan before or after the carbogen
    inhalation therapy—were acceptable in the medical
    community. 
    Id., 210–11. Since
    Wasfi, this court has not addressed this issue.
    We find instructive, however, this court’s decisions
    regarding the schools of thought doctrine. Although that
    doctrine is separate and distinct from the acceptable
    alternatives doctrine, it is similar in that both doctrines
    recognize that there may be more than one acceptable
    approach to treating a patient. Under this doctrine, ‘‘the
    law will not judge between different medical schools
    of thought so long as a physician acts according to the
    standards within that school. . . . [This charge is
    proper only if there is evidence that the practitioner]
    adhered to a recognized school of good standing, which
    has established rules and principles of practice for the
    guidance of all its members, as respects diagnosis and
    remedies, which each member is supposed to observe
    in any given case.’’ (Citation omitted; internal quotation
    marks omitted.) 
    Id., 207–208. In
    determining whether there is sufficient evidence
    to support a schools of thought instruction, this court
    has held that ‘‘a conflict in the evidence of the experts,
    as is to be expected in [medical malpractice] cases,’’ is
    not sufficient to support the charge. Geraty v. Kauf-
    man, 
    115 Conn. 563
    , 571, 
    162 A. 33
    (1932); see also
    Katsetos v. Nolan, 
    170 Conn. 637
    , 653, 
    368 A.2d 172
    (1976) (schools of thought instruction is proper when
    there is evidence of more than one school of thought
    recognized in medical community and defendant fol-
    lowed different school of thought than plaintiff’s
    expert). Rather, there must be testimony that different
    schools of thought exist and what each school of
    thought requires regarding procedure and treatment.
    Geraty v. 
    Kaufman, supra
    , 571; see also Savoie v.
    Daoud, 
    101 Conn. App. 27
    , 38–39, 
    919 A.2d 1080
    (2007)
    (proper to instruct on schools of thought doctrine when
    expert testified about existence of two schools of
    thought).
    It is the nature of medical malpractice cases that there
    often will be conflicting expert testimony regarding the
    standard of care. Wasfi makes clear that, similar to the
    schools of thought doctrine, the acceptable alternatives
    doctrine does not apply in every medical malpractice
    case but, rather, applies only when there is evidence
    of more than one acceptable method of inspection, diag-
    nosis, or treatment. See Wasfi v. 
    Chaddha, supra
    , 
    218 Conn. 211
    (‘‘the defendant physician who claims that he
    employed one of several alternative methods accepted
    within his profession has no less a task than any defen-
    dant physician: to offer credible expert evidence that
    his conduct was accepted within the profession, and
    to persuade the jury to believe that evidence’’ (empha-
    sis omitted)).
    Consequently, as with the schools of thought doc-
    trine, competing expert testimony by itself is not suffi-
    cient to support the acceptable alternatives charge. For
    example, if expert A testifies that the standard of care
    requires diagnosis to be made using the X method, and
    expert B testifies that the standard of care requires
    diagnosis to be made using the Y method, the jury must
    decide between the two alternatives, with only one
    option satisfying the standard of care. There would be
    no evidence that both methods were acceptable alterna-
    tives because both experts testified that only one
    method would satisfy the standard of care. Rather, to
    justify the charge, a qualified expert must testify that
    there is more than one acceptable method of inspection,
    treatment, or diagnosis.
    The evidence in the present case played out like the
    hypothetical just described: no expert testimony estab-
    lished that conducting the digital rectal exam either
    before the episiotomy repair or after the episiotomy
    repair was an acceptable method of diagnosing the level
    of degree of extension. Rather, the plaintiff’s expert,
    Young, testified that the only acceptable method was to
    conduct this examination prior to the repair. In contrast,
    one of the defendants’ experts, Ling, testified that this
    examination should be performed after the repair, to
    prevent contamination and infection. Additionally,
    Girard herself never testified that she made a choice
    regarding when to conduct the digital rectal exam but,
    rather, testified that she was trained to conduct this
    exam only after the episiotomy repair.
    The defendants respond that there was evidence that
    both methods were acceptable alternatives because
    Ling never testified that a prerepair examination was
    a deviation from the standard of care; he merely testified
    that a prerepair examination was not required. The
    defendants focus on Ling’s testimony that a prerepair
    digital rectal examination was ‘‘going beyond what the
    standard of care would require . . . .’’ The defendants
    take Ling’s statement out of context, however. Ling did
    not testify that a prerepair examination went beyond
    the standard of care in that it satisfied the standard of
    care by doing more than the standard of care required
    and, thereby, was an acceptable alternative to a postre-
    pair examination. Rather, Ling testified that the stan-
    dard of care does not require a prerepair examination
    because it ‘‘is actually frowned upon’’ and ‘‘discour-
    age[d]’’ due to the increased likelihood of contamina-
    tion and infection. Ling further testified that, because
    a prerepair examination can even create an opening in
    the rectum, ‘‘we don’t encourage doing it unless it’s
    absolutely necessary.’’ Ling disagreed with Young that
    the standard of care required a prerepair examination,
    explaining that ‘‘[t]hat’s going beyond what the stand-
    ard of care would require, and it brings in the additional
    risks [of infection and creating an opening] by exam-
    ining [the plaintiff] before the repair is done . . . .’’
    Ling never opined that a prerepair examination was
    an acceptable alternative to a postrepair examination
    approved by the medical community. Rather, Ling tes-
    tified that prerepair examination was a disapproved
    method of diagnosis unless ‘‘absolutely necessary.’’
    Additionally, the defendants rely on Young’s testi-
    mony to support the acceptable alternatives charge.
    Specifically, they point to Young’s testimony that,
    although she opined that the standard of care required a
    prerepair examination, a postrepair examination could
    identify a fourth degree episiotomy extension. Again,
    the defendants take this testimony out of context. On
    cross-examination, Young testified that, in a previous
    deposition, she had testified that, after a repair is per-
    formed, a digital rectal exam can establish the existence
    of a fourth degree extension. Young clarified at trial
    that a tear of the rectum would be noticeable only
    during a digital rectal examination postrepair if the
    repair had been done improperly so that the three layers
    above the rectal mucosa remained torn, allowing the
    physician to see from the vagina through the tear to
    the rectal mucosa. In essence, Young’s testimony was
    that a postrepair digital rectal exam was an acceptable
    alternative only if the physician was negligent in per-
    forming the repair. Accordingly, this record did not
    support an acceptable alternatives charge.
    Moreover, neither party at trial argued that the expert
    testimony established that Girard chose between two
    acceptable alternatives in performing the digital rectal
    examination postrepair. Both parties argued during
    summation that there was only one proper method of
    examination to properly diagnose the degree of the
    episiotomy extension—the plaintiffs’ counsel argued
    that the exam had to occur prerepair, whereas the
    defendants’ counsel argued that the exam had to occur
    postrepair. The defendants’ counsel even went so far
    as to argue that she ‘‘couldn’t believe [that] . . . Young
    would even suggest that [a prerepair examination] was
    a good idea, much less the standard of care.’’ Similarly,
    the plaintiffs’ counsel noted that there was ‘‘no agree-
    ment on the alternatives. . . . Young was very clear
    [that] the examination has to be done before you do
    the repair; [Ling] was very clear [that] you do the exami-
    nation after the repair. There is no agreement on that.’’
    Although closing argument is not evidence itself, it is
    noteworthy that, at trial, not even the parties thought
    the evidence established that the competing inspection
    methods were acceptable alternatives.
    In light of the evidence presented at trial, the trial
    court improperly instructed the jury on the acceptable
    alternatives charge.
    C
    The plaintiffs contend that this instructional error
    was harmful because merely injecting an inapplicable
    doctrine into the case creates a ‘‘substantial’’ likelihood
    of prejudice. More specifically, they argue that the
    charge ‘‘ ‘exculpate[d]’ ’’ the defendants and interfered
    with the jury’s assessment of credibility by suggesting
    that both methods of inspection were reasonable as
    long as Girard used her ‘‘best judgment.’’ The plaintiffs
    argue that the harm of this charge is evident from the
    jury’s request for additional guidance regarding the
    standard of care, the trial court’s repetition of the
    charge in response to the jury’s clarifying questions,
    and the fact that this charge was the last charge the
    jury heard.7
    The defendants respond that the improper charge
    was harmless because the dispositive issue at trial was
    not whether Girard breached the standard of care by
    performing the digital rectal examination after the episi-
    otomy repair but, rather, whether a fourth degree exten-
    sion of the episiotomy existed. To establish liability,8
    the plaintiffs had to prove that Girard failed to identify
    a fourth degree episiotomy extension and failed to prop-
    erly examine and repair that fourth degree extension.
    The defendants contend that, because the jury found
    that Girard did not breach the standard of care, it neces-
    sarily found that no fourth degree extension existed,
    and, thus, the acceptable alternatives charge did not
    taint the verdict because whether Girard performed the
    proper exam mattered only if there was a fourth degree
    extension. The defendants contend that the instruction
    did not interfere with the jury’s credibility determina-
    tion or improperly exculpate Girard. We agree with
    the defendants.
    ‘‘[N]ot every error is harmful. . . . [B]efore a party
    is entitled to a new trial . . . he or she has the burden
    of demonstrating that the error was harmful. . . . An
    instructional impropriety is harmful if it is likely that
    it affected the verdict. . . . [W]e consider not only the
    nature of the error, including its natural and probable
    effect on a party’s ability to place his full case before
    the jury, but the likelihood of actual prejudice as
    reflected in the individual trial record, taking into
    account (1) the state of the evidence, (2) the effect of
    other instructions, (3) the effect of counsel’s arguments,
    and (4) any indications by the jury itself that it was
    misled.’’ (Internal quotation marks omitted.) Allison v.

    The inclusion of an inapplicable doctrine may be
    harmful if it confuses and misleads the jury, which may
    be evidenced by the jury’s having requested additional
    guidance from the court on the doctrine; see, e.g., State

    Despite an instructional error, if the error did not
    affect the jury’s verdict, courts of this state have found
    the error to be harmless. See, e.g., Burke v. Mesniaeff,

    was not misleading and, thus, not harmful when error
    did not affect principal issue in case); see also State v.

    tional error, ‘‘[a] verdict should not be set aside where
    the jury reasonably could have based its verdict on the
    evidence’’). Cases in which the inclusion of an inapplica-
    ble doctrine have been held harmful have involved the
    submission of an issue or doctrine that affected the
    jury’s determination of liability. See Faulkner v. Reid,
    
    176 Conn. 280
    , 281, 
    407 A.2d 958
    (1978) (instructing on
    inapplicable special defense that affected determina-
    tion of liability); Miller v. Porter, 
    156 Conn. 466
    , 470,
    
    242 A.2d 744
    (1968) (same).
    In the present case, all the experts agreed that, if
    there had been a fourth degree extension of the episiot-
    omy, the standard of care would require Girard to diag-
    nose it and to repair it as a fourth degree extension
    regardless of whether the digital rectal exam was per-
    formed before or after the episiotomy repair. Addition-
    ally, Young conceded that, if there was only a third
    degree extension, the repair was properly done and
    Girard did not breach the standard of care. Thus, regard-
    less of whether the jury found either or both methods
    of inspection acceptable, there would be a breach of
    the standard of care only if the plaintiff had sustained
    a fourth degree episiotomy extension and Girard had
    failed to properly repair it. In other words, even if a
    prerepair exam was required for a fourth degree exten-
    sion, if there was only a third degree extension, there
    would be no breach. If there was a fourth degree exten-
    sion, regardless of whether a digital rectal exam was
    required before or after the repair, there would be a
    breach of the standard of care because the fourth degree
    extension was not diagnosed and repaired. The timing
    of the exam was relevant to the issue of breach only
    if the jury found there was a fourth degree episiot-
    omy extension.
    This is made clear by the court’s recitation of the
    plaintiffs’ allegations in its jury instruction, to which
    the plaintiffs did not take exception. See footnote 8 of
    this opinion. The trial court instructed that the plaintiffs
    had alleged that Girard breached the standard of care
    by failing ‘‘to identify a fourth degree extension of the
    median episiotomy’’ and by failing ‘‘to properly examine
    and adequately repair a fourth degree extension of the
    episiotomy.’’ The allegations were premised on the exis-
    tence of a fourth degree extension. Only if there had
    been a fourth degree extension would Girard have failed
    to properly inspect, diagnose, and repair it. In the
    absence of a fourth degree extension, there was no
    breach of the standard of care.
    The jury interrogatories establish that the jury found
    that the plaintiffs had established the standard of care
    but that there was no breach of that standard of care.
    This necessarily means that the jury found that the
    plaintiff sustained a third degree, not a fourth degree,
    episiotomy extension. As explained, applying the plain-
    tiffs’ alleged standard of care, there would be a breach
    in the present case only if there had been a fourth
    degree extension, and there would be no breach only
    if there had been a third degree extension. Accordingly,
    whether Girard properly conducted the digital rectal
    exam did not affect the jury’s verdict. As a result, the
    inapplicable acceptable alternatives charge, which was
    premised on the proper inspection technique, did not
    taint the jury’s verdict. Because the jury’s finding cen-
    tered on whether there was a third or fourth degree
    episiotomy extension, the inclusion of this charge,
    which had no bearing on the degree of the extension,
    would not have confused or misled the jury and, there-
    fore, was harmless. See State v. 
    Torrence, supra
    , 
    196 Conn. 438
    (holding that instructional error was not mis-
    leading, and thus not harmful, when error did not affect
    verdict, which was premised on different issue); State
    v. 
    Acklin, supra
    , 
    9 Conn. App. 666
    (same).
    The out-of-state cases on which the plaintiffs rely in
    support of their argument that an inapplicable accept-
    able alternatives charge necessarily confuses and mis-
    leads the jury are distinguishable. In those cases, the
    erroneous acceptable alternatives charge was deemed
    harmful on the ground that it was reasonably probable
    that it affected the jury’s verdict because the primary
    issue in each case was the propriety of the defendant
    physician’s decision to use a certain inspection, diagno-
    sis, or treatment method. See Hirahara v. Tanaka, 
    87 Haw. 460
    , 464–65,

    The plaintiffs respond that harm is evident in the
    present case because the improper charge was repeated
    and it was the last charge presented to the jury. We have
    considered these factors in determining the prejudice
    of an inapplicable charge and have found them persua-
    sive in cases in which the inapplicable charge tainted
    the jury’s verdict and, thus, served to confuse and mis-
    lead the jury. See Velardi v. 
    Selwitz, supra
    , 
    165 Conn. 639
    (instructional error was harmful when it involved
    jury’s determination of liability); Conlon v. G. Fox &
    
    Co., supra
    , 
    165 Conn. 113
    (‘‘[the inapplicable charge]
    clearly was involved in [the jury’s] deliberations’’). As
    discussed, the acceptable alternatives charge did not
    taint the verdict in the present case because it did not
    affect the basis of the jury’s verdict—the degree of
    the episiotomy extension. See, e.g., Burke v. 
    Mesniaeff, supra
    , 
    334 Conn. 121
    –22 (holding that improper instruc-
    tion was harmless when it did not taint jury’s verdict).
    Additionally, although the trial court repeated the
    acceptable alternatives charge in response to the jury’s
    request for clarification, the court first reread the stan-
    dard charge on medical malpractice, which was based
    on the model medical malpractice jury instructions on
    the Judicial Branch website. The court then reread the
    acceptable alternatives charge. The court continued its
    supplemental charge by reminding the jury that ‘‘the
    plaintiffs have the burden of proving by a fair prepon-
    derance of the evidence that [Girard’s] conduct repre-
    sented a breach of the standard of care. Under our law,
    the plaintiffs must prove this by expert testimony. More
    specifically, they must establish through expert testi-
    mony both what the standard of care is and their allega-
    tion that [Girard’s] conduct represented a breach of
    that standard. . . . Specifically . . . the plaintiffs
    have alleged that [Girard] . . . [breached the standard
    of care] in that she failed to identify a fourth degree
    extension of the median episiotomy and failed to prop-
    erly examine and adequately repair a fourth degree
    extension of the episiotomy.’’ Although the trial court
    repeated the acceptable alternatives charge, the court
    put it into context by reemphasizing that the plaintiffs’
    allegations were premised on a fourth degree extension,
    which must exist for the inspection technique issue to
    be material, thus diminishing any harm caused by the
    repetition of the inapplicable charge.9
    The plaintiffs further argue that harm is evidenced by
    the jury’s having sought clarification on the inapplicable
    charge. Although the jury sought clarification on the
    instruction, it did not seek clarification on the accept-
    able alternatives charge. Rather, the jury sought clarifi-
    cation on what evidence it could consider in determin-
    ing whether the plaintiffs satisfied their burden of
    establishing the standard of care. The jury also sought
    clarification on whether the plaintiffs were asserting
    that a digital rectal exam had to be conducted before
    the repair to comply with the standard of care.
    The plaintiffs argue that, although these questions
    were not specifically about the acceptable alternatives
    charge, they show that the jury was focused on the
    method of examination—the subject of the acceptable
    alternatives charge. We are not persuaded. These ques-
    tions show that the jury was focused on the standard
    of care. As discussed, the standard of care involved the
    inspection technique only if the jury first found that a
    fourth degree extension had existed, which it did not
    find on the basis of its finding that there was no breach
    of the standard of care. Thus, the jury’s focus on the
    standard of care did not necessarily suggest a focus on
    the acceptable alternatives charge.
    Finally, the plaintiffs argue that the acceptable alter-
    natives charge was harmful because it exculpated
    Girard and improperly interfered with the jury’s deter-
    mination of the experts’ credibility by suggesting that
    both inspection methods were reasonable as long as
    Girard used her ‘‘best judgment.’’ We disagree.
    It is true that, if a jury finds that expert testimony
    establishes that there were acceptable alternative meth-
    ods for conducting an inspection and that a defendant
    reasonably chooses from among those options, the
    defendant avoids liability. See Wasfi v. 
    Chaddha, supra
    ,
    
    218 Conn. 209
    (‘‘physicians may choose between alter-
    native acceptable methods without incurring liability
    solely because that choice may have led to an unfortu-
    nate result’’). This does not mean, however, that charg-
    ing the jury on the acceptable alternatives doctrine
    exculpates the defendant. As this court in Wasfi
    explained, the doctrine does not ‘‘[shield] a defendant
    physician from liability every time experts differ con-
    cerning his choice of techniques.’’ 
    Id., 211. Rather,
    the
    jury still must determine whether both of the competing
    methods were acceptable in the medical community
    and whether the defendant’s use of a particular method
    breached the standard of care.
    Despite its flaws, the acceptable alternatives charge
    did not require the jury to exculpate Girard. Rather, the
    charge informed the jury that it must decide whether
    there was more than one recognized method of inspec-
    tion and, if there was, then determine whether the
    ‘‘method [used] was consistent with the skill, care, and
    diligence ordinarily had and exercised by other special-
    ists in her field in like cases at the time that she provided
    treatment.’’ Similarly, the charge did not interfere with
    the jury’s determination of credibility by suggesting that
    both methods of inspection were reasonable. The
    charge properly left the jury to determine whether the
    expert testimony established that both methods of
    inspection were accepted in the medical community.
    Moreover, the jury did not need to reach this issue
    unless it found that a fourth degree episiotomy exten-
    sion had existed. It did not.
    Accordingly, on the basis of this record, the trial
    court’s improper inclusion of the acceptable alterna-
    tives charge was harmless.10
    II
    The plaintiffs’ final claim of instructional error is that
    the trial court’s supplemental charge to the jury improp-
    erly limited their allegations of breach of the standard
    of care to improper inspection, rather than more
    broadly to improper inspection, diagnosis, and repair
    of a fourth degree episiotomy extension.11 According
    to the plaintiffs, even if Girard properly conducted the
    inspection, she still could have breached the standard
    of care by failing to diagnose and repair a fourth degree
    episiotomy extension. The plaintiffs argue that this
    improper supplemental instruction was harmful
    because, by narrowing the allegations of breach to the
    inspection technique, the trial court focused the jury’s
    attention on the improper acceptable alternatives
    charge, which was based on the inspection technique.
    The defendants respond that the trial court’s supple-
    mental instruction was proper because, although the
    plaintiffs alleged that Girard improperly inspected, diag-
    nosed, and repaired the episiotomy extension, the
    improper diagnosis and repair were premised on the
    improper inspection. In other words, the only evidence
    of breach of the standard of care was that Girard
    improperly conducted the digital rectal examination
    postrepair, causing her not to be able to visualize the
    tear in the rectal mucosa, and thereby causing her not
    to be able to diagnose and repair that tear. We agree
    with the defendants.
    The following additional procedural history is rele-
    vant to this claim. After being instructed, the jury sought
    clarification on whether ‘‘the plaintiff[s] assert that an
    internal rectal exam must be completed before repair
    as a required component of the standard of care.’’ The
    trial court proposed to respond that ‘‘[t]he plaintiffs’
    expert, [Young], testified that an internal rectal exam
    must be performed before a repair in order to comply
    with the standard of care.’’ The plaintiffs’ counsel
    objected, arguing that the jury did not ask what the
    expert had testified to but what the plaintiffs were
    asserting, which was broader—that the standard of care
    required Girard to properly inspect, diagnose and repair
    the fourth degree extension. The plaintiffs’ counsel rec-
    ognized the specifics of Young’s testimony but argued
    that the trial court’s response was too narrow. The trial
    court disagreed and gave the supplemental instruction
    that it had proposed.
    ‘‘In evaluating a claim that a supplemental charge is
    erroneous we must examine both the main and supple-
    mental charge as a whole to determine whether the
    jury could reasonably have been misled. . . . We must
    recognize, however, that [a] supplemental charge . . .
    enjoy[s] special prominence in the minds of the jurors
    because it is fresher in their minds when they resume
    deliberation.’’ (Citation omitted; internal quotation

    given in immediate response to a request are more
    informal and expressed with less exactness than are
    studiously prepared formal charges’’; (internal quota-
    tion marks omitted)

    , 537, 
    316 A.2d 387
    (1972).
    The trial court’s response to the jury’s question
    regarding the plaintiffs’ allegations was consistent with
    the evidence presented at trial and how the plaintiffs’
    counsel had argued the plaintiffs’ case to the jury. See
    Blatchley v. Mintz, 
    81 Conn. App. 782
    , 787–88, 
    841 A.2d 1203
    (‘‘court properly tailored its instructions to reflect
    the issues actually before the jury’’), cert. denied, 
    270 Conn. 901
    , 
    853 A.2d 519
    (2004); see also Stokes v. Nor-
    wich Taxi, 
    LLC, supra
    , 
    289 Conn. 476
    , 485 (charge
    must be supported by evidence and adapted to issues in
    case). The evidence offered in support of the plaintiffs’
    theory that Girard breached the standard of care came
    from Young, who testified that Girard improperly failed
    to conduct the digital rectal exam before the episiotomy
    repair, which caused her to misdiagnose and improperly
    repair the fourth degree extension as a third degree
    extension because a fourth degree extension can be
    identified only before the repair. The plaintiffs’ allega-
    tions that Girard breached the standard of care by fail-
    ing to diagnose and repair a fourth degree extension
    were premised on a failure to conduct the digital rectal
    exam prior to the repair. The plaintiffs’ counsel argued
    in summation that the plaintiff sustained a fourth degree
    episiotomy extension and that, because there was a
    fourth degree episiotomy extension, the standard of
    care required a prerepair digital rectal exam, without
    which Girard could not properly diagnose and repair the
    degree of the extension.12 Under the plaintiffs’ theory
    of the case, the jury first had to find that a fourth degree
    episiotomy existed and then had to find that Girard
    failed to properly diagnose and repair it, which was
    caused by Girard’s failure to conduct a prerepair digital
    rectal exam. In light of this and the more informal nature
    of supplemental instructions, it was proper for the trial
    court to instruct the jury that the plaintiffs were
    asserting that a prerepair digital rectal exam was a
    component of the standard of care.
    The crux of the plaintiffs’ argument appears to be
    that, in light of the trial court’s improper charge on
    the acceptable alternatives doctrine, its supplemental
    charge was improper because, when looking at those
    two portions of the jury instructions together, the jury
    could have improperly found that, although there was
    a fourth degree episiotomy extension, insofar as both
    inspection methods were reasonable, there was no
    breach of the standard of care, which was limited to
    the inspection technique. We are not persuaded that
    the supplemental instruction improperly limited the
    allegations and had this effect.
    The jury asked if a prerepair exam was a component
    of the plaintiffs’ alleged standard of care. The trial court
    responded in the affirmative. Nothing about this
    response negates the plaintiffs’ allegation that, as a
    result of breaching the standard of care by failing to
    perform a prerepair inspection, Girard failed to diag-
    nose and repair a fourth degree extension. Under the
    plaintiffs’ theory of the case, assuming there was a
    fourth degree episiotomy extension, a failure to perform
    the prerepair exam was a necessary first component
    in a breach of the standard of care.
    Furthermore, this charge must be read in context
    as part of the entire instruction. See, e.g., Stewart v.
    Federated Dept. Stores, Inc., 
    234 Conn. 597
    , 606, 
    662 A.2d 753
    (1995). In its original charge, the trial court
    stated that the plaintiffs had alleged that Girard
    breached the standard of care ‘‘in that she, [a], failed
    to identify a fourth degree extension of the median
    episiotomy or, [b], failed to properly examine and ade-
    quately repair a fourth degree extension of the episiot-
    omy.’’ After the supplemental charge at issue, the jury
    requested clarification on what evidence it could con-
    sider in determining if the plaintiffs established the
    standard of care, in response to which the trial court
    again stated the plaintiffs’ allegations regarding breach
    of the standard of care as ‘‘[a failure] to identify a fourth
    degree extension of the median episiotomy and [a fail-
    ure] to properly examine and adequately repair a fourth
    degree extension of the episiotomy.’’ This charge, which
    was nearly identical to the language that the plaintiffs
    sought to have the court include in the first supplemen-
    tal charge, was the last charge the jury heard. See foot-
    notes 9 and 11 of this opinion. Thus, to the extent that
    the first supplemental charge did limit the plaintiffs’
    allegations, the second supplemental charge cured any
    error. See State v. Snook, 
    210 Conn. 244
    , 271, 
    555 A.2d 390
    , cert. denied, 
    492 U.S. 924
    , 
    109 S. Ct. 3258
    , 106 L.
    Ed. 2d 603 (1989). When we examine the charge as a
    whole, as we must, we conclude that it is clear that
    the trial court instructed the jury that the plaintiffs’
    allegations regarding breach of the standard of care
    included insufficient inspection, diagnosis, and repair
    of a fourth degree episiotomy extension. The jury
    instructions as a whole would not have confused and
    misled the jury into determining that, even if a fourth
    degree episiotomy extension had existed, Girard did
    not breach the standard of care.
    Accordingly, we conclude that the trial court did not
    improperly limit the plaintiffs’ allegations regarding
    breach of the standard of care in responding to the
    jury’s request for clarification of the jury instructions.
    The judgment is affirmed.
    In this opinion the other justices concurred.
    1
    Because Michael Kos’ loss of consortium claims are derivative of Laura
    Kos’ medical malpractice claims, we refer to Laura Kos as the plaintiff, to
    Michael Kos by his name, and to them collectively as the plaintiffs.
    2
    Lawrence + Memorial Hospital and Thameside OB/GYN Center, P.C.,
    also were named as defendants, but the plaintiffs withdrew the action as
    to those defendants prior to trial. We therefore refer in this opinion to Girard
    and Physicians for Women’s Health, LLC, as the defendants.

    A first degree episiotomy extension is a superficial laceration involving
    the vaginal mucosa—the lining of the vagina—and the perineal body. A
    second degree episiotomy extension is a deeper tear into the tissue, going
    beyond the vaginal mucosa and perineal body into the bulbocavernosus
    muscles, as well as extending into the perineal body—the area between the
    anus and the vagina. A third degree episiotomy extension includes a second
    degree extension and extends to the perineal muscles and anal sphincter
    but does not include the rectal mucosa—the lining of the rectum. A fourth
    degree episiotomy extension includes a third degree extension and extends
    to the rectal mucosa.
    4
    The plaintiffs also contend that the acceptable alternatives charge was
    improper because it included language regarding ‘‘schools of thought’’ and
    ‘‘best judgment.’’ The plaintiffs argue that the ‘‘schools of thought’’ wording
    improperly conflates the acceptable alternatives doctrine with the schools
    of thought doctrine, two separate and distinct doctrines. The plaintiffs also
    argue that the ‘‘best judgment’’ wording improperly injects a subjective
    standard into a medical malpractice action, excusing Girard from liability
    and interfering with the jury’s credibility determination. The plaintiffs did
    not object to the wording of the charge at the time of trial. Rather, they
    took a general exception to the charge being given at all, arguing that
    no evidence supported it and that it improperly interfered with the jury’s
    credibility determination because this kind of charge suggested that both
    methods of inspection were reasonable. At no time did the plaintiffs request
    that the trial court modify the language of the charge in any way. Although
    the plaintiffs mentioned the phrase, ‘‘schools of thought,’’ they did not do
    so to object to the inclusion of this language in the charge but, in passing,
    in summarizing the holding of Wasfi v. Chaddha, 
    218 Conn. 200
    , 
    588 A.2d 204
    (1991).
    An objection to the giving of a jury instruction does not preserve an
    objection to the specific wording of the instruction. See State v. Coleman,
    
    304 Conn. 161
    , 174, 
    37 A.3d 713
    (2012); 
    id., 173–74 (defendant
    failed to
    preserve specific objection to wording of charge when he objected at trial
    to charge on different ground); State v. Johnson, 
    288 Conn. 236
    , 287–88,
    
    951 A.2d 1257
    (2008) (same); State v. Melendez, 
    74 Conn. App. 215
    , 229, 
    811 A.2d 261
    (2002) (‘‘although defense counsel objected to giving the jury an
    instruction on consciousness of guilt, he did not object at any time to the
    wording of the instruction as given and therefore failed to preserve that
    issue for review’’), cert. denied, 
    262 Conn. 951
    , 
    817 A.2d 111
    (2003).
    Although we hold that the claim was not properly preserved, we note
    that this court in Wasfi indicated that the phrase, ‘‘schools of thought,’’
    should not be included as part of the acceptable alternatives charge; Wasfi
    v. 
    Chaddha, supra
    , 
    218 Conn. 208
    –209; see also 
    id., 208 (noting
    ‘‘unfortunate
    use’’ of schools of thought language); but nonetheless concluded that the
    inclusion of this phrase in the acceptable alternatives charge, which was
    otherwise substantively correct, did not constitute instructional error or
    confuse the jury, which would not have been aware of the legal difference
    between the two doctrines. 
    Id., 209. We
    also rejected the argument that the
    acceptable alternatives doctrine opened a ‘‘Pandora’s Box’’ by injecting a
    subjective standard into the objective medical malpractice test. 
    Id., 211. Specifically,
    we disagreed that the doctrine would shield a defendant from
    liability when experts have differing opinions or would take credibility
    determinations away from the jury because the doctrine requires defendants
    to offer expert evidence that acceptable alternatives exist and to persuade
    the jury to credit this evidence. 
    Id. 5 Flynn
    testified that, even if Girard had breached the standard of care
    by diagnosing and repairing a fourth degree episiotomy extension as a third
    degree extension, the plaintiff would not have necessarily sustained any
    damages because such a small hole would have healed on its own.
    6
    The trial court instructed the jury as follows: ‘‘In this case, you have
    heard testimony from different physicians as to different ways to inspect and
    diagnose an episiotomy extension. Where there is more than one recognized
    method of treatment and not one of them is exclusively and uniformly used
    by all physicians in good standing, a health care provider is not negligent
    in selecting one, which, according to his or her best judgment, is best suited
    for the patient’s needs, even if it turns out to be a selection not favored by
    another physician. Now, there may be more than one established system
    of treatment. The law does not favor or give exclusive recognition to any
    particular system of treatment over another. The law is that a physician is
    not bound to use any particular method or medical school of thought in
    treating a patient. When a physician of ordinary skill and learning recognizes
    more than one method of treatment as proper, the physician may adopt
    any such method without subjecting himself or herself to liability for an
    unfortunate result, so long as such method was consistent with the skill,
    care, and diligence ordinarily had and exercised by other specialists in her
    field in like cases at the time that she provided the treatment. Thus, if there
    was more than one established method of treatment recognized at the time,
    the test is not whether the physician adopted a method someone else might
    have adopted but, rather, whether the method adopted was one that was
    in compliance with reasonable skill, care, and diligence required of the
    particular school of thought embracing the method.’’
    7
    The plaintiffs further argue that the harm caused by the improper charge
    was worsened by the improper wording of the charge, confusing the accept-
    able alternatives doctrine with the schools of thought doctrine and injecting
    a subjective ‘‘best judgment’’ standard into the objective medical malpractice
    standard. As explained in footnote 4 of this opinion, the merits of these
    claims are unpreserved. Nevertheless, we note that, in Wasfi, we held that the
    inclusion of the phrase, ‘‘schools of thought,’’ in an acceptable alternatives
    charge, although incorrect, does not confuse or mislead the jury. See footnote
    4 of this opinion. The charge at issue in the present case is nearly identical
    to the charge in Wasfi, and, as in that case, we fail to discern how the
    inclusion of this phrase would create any additional confusion for the jury.
    Moreover, to the extent that the plaintiffs contend that the ‘‘best judgment’’
    language was harmful, we address that argument, but, to the extent that
    the plaintiffs attempt to raise their unpreserved claim regarding whether
    the inclusion of the ‘‘best judgment’’ language was improper, we decline to
    review that issue.
    8
    In the operative fifth amended complaint, the plaintiffs allege that Girard
    breached the standard of care by failing ‘‘to identify a [fourth] degree exten-
    sion of the median episiotomy’’; failing ‘‘to perform a proper and adequate
    episiotomy repair’’; and failing ‘‘to properly examine the episiotomy repair
    after it was complete.’’ To conform the allegations to the evidence presented
    at trial, the plaintiffs proposed to amend the complaint to allege that Girard
    breached the standard of care by failing ‘‘to identify a [fourth] degree exten-
    sion of the median episiotomy’’ and by failing ‘‘to properly examine and
    adequately repair the [fourth] degree extension of the episiotomy.’’ The trial
    court denied the plaintiffs’ request to amend the complaint, but the trial
    court’s instruction regarding the plaintiffs’ allegations nevertheless tracked
    how the plaintiffs had set forth those allegations in their proposed sixth
    amended complaint.
    9
    Additionally, contrary to the plaintiffs’ contention, the acceptable alterna-
    tives charge was not the last charge that the jury heard, but, rather, the last
    charge was on the burden of proof and a summary of the plaintiffs’ allegations
    centering on the disputed existence of a fourth degree extension. See State
    v. 
    Torrence, supra
    , 
    196 Conn. 437
    –38 (‘‘trial court’s concluding instruction
    . . . refocused the jury’s attention on the key concept [at issue] . . . and,
    in effect, acted as a curative instruction’’).
    10
    Alternatively, the plaintiffs ask this court to abolish the acceptable
    alternatives doctrine because it is unnecessary in light of the standard jury
    instruction regarding medical malpractice, and because it misleads the jury
    and interferes with its credibility determination by suggesting that a physi-
    cian is not liable if the physician’s methods were subjectively reasonable.
    In light of this court’s stare decisis jurisprudence and our holding that the
    acceptable alternatives charge in this case was harmless, we decline to
    take this opportunity to abolish the acceptable alternatives doctrine. ‘‘The
    doctrine [of stare decisis] requires a clear showing that an established rule
    is incorrect and harmful before it is abandoned.’’ (Emphasis added; internal
    quotation marks omitted.) Conway v. Wilton, 
    238 Conn. 653
    , 660–61, 
    680 A.2d 242
    (1996). Moreover, because we conclude that the acceptable alternatives
    doctrine was not applicable in this case, we determine that this is not the
    appropriate case for deciding whether the doctrine should be abolished.
    11
    Specifically, after the plaintiffs’ counsel objected to the trial court’s
    proposed supplemental instruction as being too narrow, counsel requested
    that the trial court respond to the jury’s question that the plaintiffs’ allega-
    tions were that Girard breached the standard of care by failing to ‘‘carefully
    inspect and properly diagnose a fourth degree laceration.’’
    12
    The plaintiffs’ counsel argued: ‘‘So, step one is, was it a fourth degree
    [laceration]? . . . It was clearly a fourth degree laceration. [Step two is,
    was] it properly repaired? Well, no, it wasn’t because [Girard] diagnosed
    what she thought and repaired what she thought was a third degree because
    she didn’t properly examine the perineum for the laceration. So, that gets
    you through the standard of care. Properly examine, properly diagnose,
    properly repair. She didn’t see the fourth degree because she didn’t do the
    examination, [so] she didn’t repair the fourth degree because she thought
    it was a third degree.’’
