Background
After her discharge from Saint Elizabeth Medical Center, Christina Swofford received a one-time intravenous dose of the antibiotic Dalbavancin at an Option Care outpatient facility. She alleged that the provider mistakenly inserted the intravenous line into an artery rather than a vein, causing an arterial occlusion that required multiple surgeries and the eventual amputation of her right ring finger and fingertips.
Swofford sued Option Care for medical malpractice and designated registered nurse Gayle Coulter as her expert. The circuit court initially ruled that Coulter’s experience in infusion therapy qualified her to address the standard of care and its breach. On reconsideration, however, the court concluded that Coulter was not qualified to establish that the alleged arterial insertion probably caused Swofford’s blood clot, treatments, and amputations. Because Swofford offered no other causation expert, the court entered summary judgment for Option Care.
The Court’s Holding
The Kentucky Court of Appeals affirmed. It explained that Kentucky does not categorically bar a nonphysician from giving expert testimony in a medical-malpractice case. Qualification instead depends on whether the witness’s knowledge, skill, experience, training, or education satisfies Kentucky Rule of Evidence 702 and will assist the factfinder on the particular issue presented.
Coulter’s credentials and experience qualified her to testify about the standard of care for intravenous placement and whether placing the line in an artery breached that standard. Her affidavit, however, did not show specialized knowledge or experience in diagnosing or treating injuries caused by arterial placement of an intravenous line. The circuit court therefore did not abuse its discretion by excluding her causation opinion. Because neither recognized exception to the expert-testimony requirement applied and Swofford presented no qualified expert evidence of causation, summary judgment was proper.
Key Takeaways
- Kentucky applies no bright-line rule preventing a properly qualified nonphysician from offering expert testimony in a medical-malpractice case.
- An expert may be qualified to address the standard of care and breach but unqualified to address medical causation.
- Without qualified causation testimony, a malpractice plaintiff cannot survive summary judgment when causation is beyond common knowledge and the defendant has made no admission establishing negligence.
Why It Matters
The decision underscores that expert qualifications must be matched to each element of a malpractice claim. Extensive nursing and infusion-therapy experience may support opinions about proper intravenous technique without establishing expertise in the medical mechanisms connecting an alleged error to vascular injury and amputation.
Attorneys designating nonphysician experts should ensure that the record specifically establishes the expert’s training and experience on causation, not merely on the relevant standard of care.
