262 So. 3d 520
Miss.2019Background
- Charles Norman Sr. suffered an ischemic stroke while an inpatient after cardiac catheterization; nursing staff documented symptoms but did not timely notify physicians, delaying recognition for at least 7.5 hours and precluding timely tPA administration.
- Anderson Regional admitted the nurses breached the standard of care and that the delay prevented possible tPA administration but disputed that Norman would have been a tPA candidate or that tPA would more likely than not have produced a substantially better outcome given his comorbidities.
- Plaintiffs' experts (notably Dr. Uschmann) opined that timely tPA would, to a reasonable medical probability, have given Norman a >50% chance of a substantially better outcome; defendants moved to exclude expert testimony and for summary judgment.
- The trial court excluded plaintiffs’ experts for lacking a reliable medical-literature foundation and granted summary judgment, concluding plaintiffs failed Mississippi’s ‘‘loss-of-chance’’ (>50%) causation requirement.
- The Supreme Court affirmed, holding expert opinions were not supported by the medical literature (which shows an absolute tPA benefit well below 50%) and therefore no genuine issue of material fact existed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of expert causation testimony | Dr. Uschmann provided a reasonable-medical-probability opinion that timely tPA would more likely than not (>50%) improve outcome | Experts lack support in peer-reviewed literature; opinions contradict established study data | Court excluded experts under Miss. R. Evid. 702 for lack of reliable literature foundation |
| Causation (loss-of-chance standard) | Loss of chance satisfied because tPA could have substantially improved outcome | Medical literature shows only an 8–12% absolute benefit from tPA—insufficient to meet >50% threshold | Plaintiff failed to show >50% chance; causation not met; summary judgment affirmed |
| Breach-of-contract claim | Conditions of Admission created contractual duty; breach deprived Norman of tPA opportunity | Claim is not distinct from malpractice; causation still required | Court treated claim as tort in substance and granted summary judgment for same reasons |
| Whether to replace loss-of-chance with reduced-likelihood approach | Argues fairness and proportional recovery for lost chance below 50% (adopt reduced-likelihood) | Mississippi precedent and comparative negligence framework support retaining all-or-nothing loss-of-chance rule | Court declined to overturn precedent and retained Mississippi’s loss-of-chance (>50%) rule |
