Narrative Opinion Summary

In a medical malpractice case adjudicated by the Supreme Court of Tennessee, the plaintiff alleged that a physician assistant, under the supervision of a physician, failed to diagnose her cardiomyopathy, resulting in injury. The plaintiff sued the clinic and the supervising physician, not the assistant directly, asserting a breach of the standard of care. The trial court granted summary judgment for the defendants, finding no breach of standards, a decision initially reversed by the Court of Appeals, which equated the physician assistant's standard of care to that of a physician. The Supreme Court overturned the appellate decision, affirming the distinct standard of care applicable to physician assistants. The case underscores the necessity for plaintiffs in medical malpractice claims to produce expert testimony establishing the relevant standard of care and proving a breach thereof. The court emphasized the supervising physician's potential vicarious liability due to the agency relationship with the assistant. However, the plaintiff's evidence, primarily the testimony of a cardiologist unfamiliar with physician assistant standards, failed to meet the required burden of proof, leading to the dismissal of the case. The ruling clarifies the differentiated standards of care and the stringent requirements for expert testimony in Tennessee medical malpractice litigation, ultimately reinstating summary judgment for the defendants.

Legal Issues Addressed

Burden of Proof in Medical Malpractice

Application: The burden of proof in medical malpractice cases lies with the plaintiff to demonstrate a breach of the applicable standard of care through competent expert testimony.

Reasoning: The court emphasized that in medical malpractice cases, the primary issue regarding expert testimony is the expert's competence under the medical malpractice statute.

Standard of Care for Physician Assistants

Application: The Supreme Court of Tennessee ruled that physician assistants are held to a distinct standard of care separate from that of physicians, contrary to the Court of Appeals' assertion.

Reasoning: The Supreme Court reversed the Court of Appeals, confirming that the standard of care for physician assistants is distinct from that for physicians.

Summary Judgment in Medical Malpractice

Application: The court granted summary judgment in favor of the defendants, concluding that the plaintiff failed to establish the necessary elements of medical malpractice due to insufficient expert testimony.

Reasoning: The trial court granted summary judgment in favor of the Defendants, ruling that the Plaintiff did not establish the relevant standard of care or causation.

Vicarious Liability of Supervising Physicians

Application: Under Tennessee law, a supervising physician may be vicariously liable for the actions of a physician assistant if an agency relationship is established.

Reasoning: Dr. Adams served as the supervising physician for Maddox, establishing an agency relationship between them, despite the absence of a written agreement outlining their specific relationship.
