Can physicians testify about nursing standards of care in Utah medical malpractice cases? De Adder v. IHC Explained

In De Adder v. IHC, the Utah Court of Appeals addressed when physicians can serve as expert witnesses regarding nursing standards of care in medical malpractice cases. This decision provides important guidance for practitioners handling medical negligence claims involving different healthcare specialties.

Background and Facts

Donalda De Adder underwent total right knee replacement surgery at an Intermountain Healthcare facility. Three days post-surgery, she developed permanent damage to her right peroneal nerve and foot drop. Her orthopedic surgeon, Dr. Jackson, concluded the injury resulted from improper use of a continuous passive motion (CPM) device ordered as post-surgical therapy. De Adder sued IHC, alleging negligent monitoring by nursing staff, and designated Dr. Jackson as her only expert witness regarding nursing standards of care.

Key Legal Issues

The central issue was whether Dr. Jackson, an orthopedic surgeon, was qualified to testify about the standard of care applicable to nurses administering CPM therapy. IHC moved for summary judgment, arguing that expert testimony was essential and that Dr. Jackson could not provide qualified testimony about nursing standards.

Court’s Analysis and Holding

The court of appeals affirmed the grant of summary judgment, holding that physicians cannot testify as experts regarding nursing standards of care unless they demonstrate specific qualifications. The court explained that practitioners from different medical specialties are ordinarily not competent to testify against each other due to “wide variation between schools in both precepts and practices.” While exceptions exist when the expert is knowledgeable about the applicable standard or when standards between specialties are the same, Dr. Jackson’s affidavit contained only conclusory statements without factual support demonstrating his familiarity with nursing protocols for CPM therapy.

Practice Implications

This decision underscores the importance of careful expert designation in medical malpractice cases. Practitioners must ensure their expert affidavits contain “specific evidentiary facts” supporting the expert’s qualifications, not merely conclusory assertions. When crossing specialty lines, experts must establish either substantial knowledge of the other specialty’s standards or demonstrate that the standards are identical. The court’s analysis reinforces that Rule 702 evaluations can occur at the summary judgment stage, making proper foundation critical from the outset.
