15 F.4th 436
6th Cir.2021Background
- April 4–13, 2016: Debra Chesnut experienced progressive right‑leg pain, numbness, and coolness beginning April 4; initial treating clinicians (ER physician and APRN) diagnosed sciatica and noted pulses.
- April 12, 2016: Debra was seen by Dr. Madden at a federally funded health center; he documented a dorsalis pedis pulse, performed osteopathic manipulative treatment, diagnosed musculoskeletal causes, and did not include vascular ischemia in his differential or refer for urgent vascular evaluation.
- April 13, 2016: Debra’s right foot turned blue; she was sent to the ER, transferred to University of Kentucky Medical Center, found to have no pulses and extensive arterial thrombosis; revascularization attempts failed and a below‑the‑knee amputation occurred on April 19.
- Procedural posture: Plaintiffs sued multiple providers; only the United States (substituted for Dr. Madden under the FTCA) remained. The district court (bench proceeding on submitted briefs and depositions) found Dr. Madden negligent but held Plaintiffs failed to prove proximate causation; judgment for the United States.
- Sixth Circuit disposition: The court reversed and remanded, holding the district court clearly erred in framing and applying Kentucky causation law and in assessing Plaintiffs’ experts’ testimony.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Standard of review for district court factual findings in a bench trial on the record | Clear‑error review is inappropriate because the trial judge never heard live testimony; de novo review appropriate | Causation/findings are mixed law/fact; Rule 52 requires clear‑error review | Clear‑error review applies to district court findings under Rule 52 despite decision on written record (Traylor, Anderson controls) |
| Whether Dr. Madden breached the standard of care | Dr. Madden negligently failed to include vascular causes in his differential and to refer for urgent vascular evaluation | Government did not contest negligence finding below | District court correctly found breach (failure to consider vascular ischemia) |
| Whether Plaintiffs proved proximate causation (substantial factor) | Experts (Drs. Kiehl and Roberts) opined it was more likely than not that timely referral/earlier heparin/earlier vascular care would have saved the leg or reduced the extent of amputation | District court: expert testimony equivocal or premised on mischaracterizations; progression of ischemia was such that earlier intervention would not have changed outcome | Sixth Circuit: district court misframed causation, misread and improperly discounted experts; clear error in finding causation not proven; remand required |
| Remedy on reversal | Remand for damages only (if causation established) | Full remand on causation and merits appropriate | Court declines immediate damages remand; reverses and remands for further proceedings on causation/merits consistent with opinion |
