Mitchell, L. v. E. Shikora, D.O., Aplts.
209 A.3d 307
Pa.2019Background
- Plaintiff Lanette Mitchell underwent a laparoscopic hysterectomy during which her colon was severed on abdominal entry; an emergency loop ileostomy repaired the bowel.
- Mitchell sued Dr. Evan Shikora and affiliated defendants for medical negligence, alleging failure to identify the colon before incision (no informed-consent or battery claims pleaded).
- Trial court excluded evidence of Mitchell’s informed consent but admitted evidence that bowel perforation is a known risk/complication of laparoscopic entry; the jury returned defense verdicts.
- Superior Court reversed, holding risks/complications evidence irrelevant and prejudicial in a pure negligence case and remanding for a new trial.
- Pennsylvania Supreme Court granted review limited to whether Brady v. Urbas permits evidence of general risks/complications in negligence claims.
- Supreme Court reversed the Superior Court, holding that evidence of surgical risks and complications (distinct from evidence of a patient’s consent) may be admissible to inform the standard of care, breach, and causation, subject to relevancy and Rule 403 limits.
Issues
| Issue | Plaintiff's Argument (Mitchell) | Defendant's Argument (Shikora) | Held |
|---|---|---|---|
| Admissibility of informed-consent evidence in negligence action | Consent evidence should be excluded as irrelevant and confusing; it risks suggesting consent to negligence | Consent evidence is irrelevant to negligence; defendants do not seek to prove assent to negligence | Court: Evidence that a patient consented is generally irrelevant and should be excluded when lack of consent is not pleaded (following Brady) |
| Admissibility of general evidence that certain injuries are known risks/complications | Risks evidence is irrelevant here; telling jurors an injury is a known complication will mislead and distract from whether doctor breached the standard of care | Risks evidence is relevant to explain surgical decision-making, the standard of care, and to show injuries may occur absent negligence | Court: Risks/complications evidence may be admissible to help establish the standard of care, breach, or causation; Superior Court erred to bar it categorically |
| Prejudice and jury confusion from risks evidence | Probative value is substantially outweighed by danger of misleading jury; it invited the jury to excuse negligence | Any risk of confusion can be managed by gatekeeping, limiting testimony, and jury instructions | Court: Trial judges must guard against prejudice and confusion under Pa.R.E. 403, but potential for confusion does not warrant categorical exclusion of risks evidence |
| Weight and reliability of studies/expert reliance on complication data | Studies that do not separate negligent from non-negligent complications are unreliable and should be excluded | Challenges to studies go to weight, not admissibility; Frye/Freirelated challenges remain available | Court: Methodological attacks generally affect weight and credibility; Frye-type challenges remain appropriate when methodology is suspect |
