Appellants sued the appellee-doctors for medical malpractice, alleging that appellant Gubbins had suffered nerve damage as a result of flawed treatmеnt she received during otherwise routine surgery at Sibley Memorial Hospital. 1 Appellants asserted liability based on traditional negligence and res ipsa loquitur. The jury found for the defendants on both allegations. 2 On appeal, appellants claim that the trial judge’s instructions and evidentia-ry rulings were in error. We affirm.
I.
Appellants first argue that the trial judge erred in giving the jury instruction on “bad result” of treatment.
See
Standard Civil Jury Instructions for the District of Columbia, No. 9.06 (2009 rev.
*468
ed.). We find no error in the giving of the instruction, and certainly none that warrants reversal. The instruction, in its standard form, informs the jury that a doctor “is not negligent simply because [his][her] efforts аre not successful,”
3
but that, while “[ujnsatisfactory results from treatment or care alone do not determine whether the defendant ... was negligent in treating the plaintiff, ... if the doctor’s perfоrmance fell below the standard of care and thereby proximately caused the patient’s injuries, then the doctor was negligent.”
Id.
As we recently pointed out, the instruction “reflеcts a principle established by rulings of this court.”
Aikman v. Kanda,
Appellants also argue that the instruction undermined their case for liability based on res ipsa loquitur, but that is not so. First, in the oral instructions on res ipsa, after telling the jury that it could “conclude from the fаct that an injury occurred that a [defendant was negligent” if certain then-specified conditions were met, the judge added that the bad-result instruction given earlier “does not apply in regard to [p]laintiff[s’] theory [of] res ipsa loquitur.” 4 Moreover, the res ipsa instruction as a whole, as well as the jury verdict form, carefully focused the jury’s attention on the findings necessary to make out that theory, including when, and when nоt, “the ... occurrence of an injury” may be sufficient to prove negligence. On this record, we have no reason to conclude that the bad-result instruction prejudiced apрellants’ case for either traditional negligence or res ipsa liability. 5
II.
Appellants argue that the trial court erred in admitting the testimony of appellees’ experts, Dr. Kelly and Dr. Anderson. Both testified that Ms. Gub-bins’s injury was due to a chemical reaction resulting from the epidural she received. According to Dr. Anderson, “Mrs. Gubbins’fs] nerves were sensitive to those particular chemicals and ... it caused some damage.... [I]t [is] not unusual for human beings to be sometimes very sensitive to medi[c]ations that other human beings aren’t .... ” —an opinion he said was based on his “education, knowlеdgef,] and experience.” Dr. Kelly held a similar opinion, which he said was based on “a combination of experience in previous
*469
cases like this, [and] reviewing the literature, that sort of thing.” Appellants argue that this testimony was inadmissible because it was based only on “prior experience” and not on “scientific methodology.” We have held, however, that an expert may base his or her opinion on clinical judgment and specialized knowledge.
See Drevenak v. Abendschein,
III.
Appellants contend that having allowed the testimony by the defendants’ experts that Ms. Gubbins may have been “susceptible” to an injury that was otherwise unexplainable — and certainly not explainable by negligence — the trial judge erred in refusing to instruct the jury, in accordance with standard civil instruction No. 13.08, 6 on the theory of “special susceptibility.”
Appellees counter that no prejudice to appellants flowed from the refusal to give the instruction because the special susceptibility theory relates only tо a plaintiff’s damages, and the jury never reached that issue; instead it found no liability on the part of either defendant. Support for ap-pellees’ position comes from authorities that view a plaintiffs special condition or susceptibility as merely
increasing
the liability — in terms of damages — of a defendant whose negligence has injured the plaintiff. An illustration is Judge Levеn-thal’s opinion for the court in
Bourne v. Washburn,
142 U.S.App. D.C. 332,
can recover for pains resulting frоm that injury that ... are not due to organic ailment but [rather] are psychosomatic in origin, and are due to the impact of the injury upon or in aggravation of a pre-existing neurotic or psychic weakness.
Id.
at 336,
But, while these authorities appear to view a plaintiffs susceptibility as related only to the issue of (augmented) damages, there is case authority holding that a requested instruction on that theory, when supported by evidence, must be given in regard to the issue of proximate causation, a component of liability.
See, e.g., Primm v. U.S. Fid. & Guar. Ins. Corp.,
Accordingly, appellants can claim no legally cognizable prejudice frоm the judge’s refusal to give the susceptibility instruction. 9
Affirmed.
Notes
. Sibley Memorial Hospital was also a named defendant, but is not a party to this appeal.
. A previous judgment for the defendants was reversed in
Gubbins v. Hurson,
. Here, the trial judge instructed the jury that "[a] doctor is not negligent simply because there was a bad result.” The difference between this instruction and the form instruction, quoted above, is not significant.
. This statement does not appear in the written instruction the jury also received.
. The standard bad-result instruction concludes with a sentence pointing out that in circumstances where the defendant-doctor was negligent "it is no defense ... that the doctor did the best that [he][she] could and that those efforts simply were not successful.” Standard Civil Jury Instructions, supra, No. 9.06. The judge did not include this sentence in the instruction given, apparently accepting the defendants’ contention that it had no place because "having done their best” was not their defense in the case. Merely having "tried one’s bеst,” however, is never a defense to negligence, and if the bad-result instruction is otherwise unobjectionable in a case, there is no reason to omit the final sentence. Nonethelеss, we can find no more prejudice to the appellants in this omission than in the judge's decision to give the bad-result instruction in the first place.
. The standard instruction provides:
If the plaintiff, because of a prior injury, disability or other condition, was more likely to suffer injury because of the defendant’s negligence than a normal person would, then the defendant is responsible for that injury. A defendant may nоt avoid responsibility for his or her negligent actions by showing that the injury would have been less serious if it had happened to someone else.
Standard Civil Jury Instructions, supra, No. 13.08.
. In
Primm,
for example, the court wrote: ''[W]e аre not convinced that [the proffered special susceptibility instruction] is merely a damage instruction. Rather, it embraces definite aspects of proximate causation when it discusses aggravation of an existing condition and predisposition of the plaintiff to injury to a greater extent than another person.”
Primm,
. This is not to say a defendant is not resрonsible for all of a plaintiff’s resultant injuries once res ipsa liability is found, even taking account of susceptibility; but, as indicated, the jury never reached the issue of damages here.
.We reject appellants’ remaining argument that the res ipsa loquitur instruction itself was erroneous or confusing as given — an argument resting on an apparent mistranscription of the oral instruction that is not reflected in the written instructions the jury also had.
