969 N.W.2d 311
Iowa2022Background:
- William McGrew underwent a right carotid endarterectomy after Dr. Otoadese (and the original radiologist) read a CT angiogram as ~65–70% stenosis; McGrew suffered a disabling right‑side stroke postoperatively.
- Plaintiffs promptly sought a second opinion: neurologist Dr. Ivo Bekavac read the CTA as ~40% stenosis and recorded that 40% ‘‘was not significant to justify endarterectomy’’; neuroradiologist Dr. John Halloran later over‑read the CTA as ~32% stenosis.
- McGrews sued Dr. Otoadese for medical negligence, designated Bekavac and Halloran as treating‑physician experts, and supplemented interrogatory answers summarizing their opinions and the contemporaneous medical records.
- The district court (relying on Hansen and rule 1.500(2)) barred Bekavac from testifying about standard of care/causation beyond treatment‑formed opinions, excluded Halloran’s record and his testimony about measurement method, and admitted Bekavac’s record only in redacted form; the jury returned a defense verdict.
- The Iowa Supreme Court held the court abused its discretion: Bekavac and Halloran were not ‘‘retained’’ experts so written reports under rule 1.500(2)(b) were not required; the 1.500(2)(c) disclosures sufficed for standard‑of‑care testimony (but not for causation); exclusion/redaction of contemporaneous records and Halloran’s testimony was erroneous and not harmless — reversed and remanded for new trial.
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether rule 1.500(2)(b) required written expert reports from treating physicians | McGrews: No — Bekavac and Halloran were not retained for litigation and thus need only comply with the lesser disclosure rule | Otoadese: Yes — when treating physicians offer opinions formed outside treatment they are effectively retained and must provide full reports | Court: 1.500(2)(b) applies only to experts actually retained/specially employed; no written reports required here |
| Adequacy of rule 1.500(2)(c) disclosures | McGrews: Supplemental interrogatory answers plus records provided a sufficient summary of facts and opinions on standard of care | Otoadese: Disclosures were vague and failed to state actual opinions on standard of care and causation | Court: Disclosures were adequate to support testimony on standard of care (surgery unnecessary given lower stenosis readings) but inadequate to disclose causation opinions |
| Admissibility of contemporaneous medical records and Halloran’s testimony about measurement method | McGrews: Records were timely disclosed in full and Halloran should be allowed to explain his 32% measurement and method | Otoadese: Records/opinions were litigation‑oriented and surprisal/prejudice warranted exclusion or redaction | Court: Excluding/redacting contemporaneous records and excluding Halloran was an abuse of discretion; those materials/opinions related to treatment‑formed views and should have been admitted (as to stenosis/standard of care) |
| Harmless‑error analysis | McGrews: Exclusion prejudiced their case because the dispute turned on degree of stenosis and the excluded evidence was material | Otoadese: Any error was harmless given plaintiffs’ retained expert testimony and other evidence | Court: Error was not harmless — excluded live testimony and records likely affected jury assessment; remand for new trial |
