Assessment of fitness for duty of underperforming physicians: The importance of using appropriate norms.

Objective: To determine whether population-specific normative data should be employed when screening neurocognitive functioning as part of physician fitness for duty evaluations. If so, to provide such norms based on the evidence currently available.

Methods: A comparison of published data from four sources was analyzed. Data from the two physician samples were then entered into a meta-analysis to obtain full information estimates and generate provisional norms for physicians.

Results: Two-way analysis of variance (Study x Index) revealed a significant main effect and an interaction. Results indicate differences in mean levels of performance and standard deviation for physicians.

Conclusions: Reliance on general population normative data results in under-identification of potential neuropsychological difficulties. Population specific normative data are needed to effectively evaluate practicing physicians.
