Background
Rick Casteel went to Saint Elizabeth Medical Center’s emergency room with stomach pain and vomiting. Radiologist John Guluzian, who worked for Radiology Associates of Northern Kentucky and provided services to the hospital under contract, interpreted an abdominal CT scan as showing no acute findings. Casteel was discharged but died the following day from a gastric perforation related to a volvulus. His estate sued Guluzian, the radiology practice, and the hospital.
The circuit court granted summary judgment to the hospital on the estate’s claim that it was vicariously liable because Guluzian was its ostensible agent. The case proceeded to trial against Guluzian and his employer. The jury unanimously found that Guluzian breached the standard of care, but nine jurors found that his breach was not a substantial factor in causing Casteel’s death. The estate appealed both the resulting defense judgment and the hospital’s dismissal.
The Court’s Holding
The Court of Appeals affirmed. It held that the circuit court did not abuse its discretion by allowing defense expert Dr. Sean Harbison to testify about Casteel’s 2015 CT scan and the difficulty of vomiting through an obstructed stomach. The vomiting testimony rebutted testimony from the estate’s expert, and much of Harbison’s testimony about the earlier scan was elicited by the estate during cross-examination. His disclosed role as a gastrointestinal surgeon addressing causation also reasonably encompassed the limited testimony, and the estate failed to demonstrate prejudice warranting a new trial.
The jury’s causation finding made the hospital’s potential vicarious liability effectively moot. The court nevertheless found no error in the hospital’s dismissal: Casteel repeatedly signed an authorization explaining that certain practitioners, including radiologists, were independent contractors rather than hospital employees, and there was no evidence that the hospital induced him to believe Guluzian was its employee or that he selected the hospital in reliance on Guluzian’s employment status.
Key Takeaways
- A claimed failure to disclose expert testimony does not justify a new trial without an abuse of discretion and resulting prejudice.
- Rebuttal testimony may be admissible when the opposing party opens the door to the subject, and a party generally cannot establish prejudice from testimony it substantially elicited on cross-examination.
- A hospital’s clear, repeatedly signed notice that radiologists are independent contractors supported rejection of ostensible agency where the patient did not rely on the radiologist’s supposed employment status.
Why It Matters
The decision underscores that a medical-malpractice plaintiff must prove causation even when the jury finds a breach of the standard of care. It also illustrates the importance of specific expert disclosures, precise record citations on appeal, and a concrete showing that challenged testimony probably affected the verdict.
For hospitals and medical contractors, the opinion shows how clear patient-facing independent-contractor disclosures can defeat ostensible-agency claims, particularly when there is no evidence of deception or patient reliance.
