491 P.3d 1088
Alaska2021Background
- Courtney Culliton was a severely disabled, terminally ill patient with a chronic seizure disorder and recurrent aspiration pneumonia; she received in‑home services from Hope Community Resources under a Medicaid waiver.
- Christine Culliton (Courtney’s mother) drafted an aspiration protocol (endorsed by Courtney’s physician) instructing caretakers to clear blockages, call 911 if Courtney was gasping or not coughing, and notify Christine and document any aspiration events.
- Hope received the protocol; a caregiver reported a suspected aspiration on August 25, 2015. Courtney was hospitalized September 10 with probable aspiration pneumonia and died September 16; hospital listed bilateral aspiration pneumonitis, chronic recurrent seizures, and cerebral palsy as causes/contributors.
- Christine (as personal representative) sued Hope for negligence alleging failures to monitor, notify, and obtain timely higher-level medical care; the superior court granted summary judgment for Hope because the estate presented no expert testimony.
- The Alaska Supreme Court reversed: expert testimony was not required to prove breach of the duty to notify because the claim alleged ordinary negligence (failure to follow the protocol), but expert medical opinion was needed on causation — and the treating physician’s deposition testimony sufficed to create a material factual dispute on causation.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether expert testimony was required to establish the standard of care/breach | Estate: No — claim is ordinary negligence (failure to notify per protocol); jurors can decide without expert | Hope: Yes — claims involve medical/professional judgment and thus require expert proof | Held: No — expert testimony not required because alleged breach did not involve professional judgment but failure to follow protocol |
| Whether expert testimony was required to prove causation between August 25 aspiration, delayed notification/treatment, and death | Estate: Causation can be shown; treating physician’s testimony supports that the Aug. 25 aspiration likely led to pneumonia and earlier treatment could have helped | Hope: Estate lacks expert proof on the complex medical links; summary judgment warranted | Held: Yes — causation requires medical expertise, but the treating physician’s deposition, viewed favorably to the estate, was sufficient to create a genuine issue of material fact |
| Whether treating physician may provide the necessary medical opinion at summary judgment | Estate: Treating physician is a hybrid witness and may offer expert opinions based on treatment/observations | Hope: Argues treating physician’s testimony is equivocal and insufficient to show causation more likely than not | Held: Treating physician may testify as a hybrid witness; her deposition, when construed in the estate’s favor, precludes summary judgment |
