Historical Trajectory and Implications of Duty-Hours in Graduate Medical Education.

Duty-hours policies continue to be debated. Most know the pro and con arguments, but many may not be aware of background information preceding and intertwining the development and implementation of these policies. Interestingly, several aspects of law were involved or potentially correlated with policies enacted. This review updates new generations of physicians and scholars on the historical trajectory of duty-hour policies and highlights policy implications and the current state of evidence. In reviewing the historical and legal trajectory of duty-hours, many updates seemed to be a reaction to potential federal entanglement. Additionally, the review of the postimplementation literature revealed minimal empirical evidence. Instead, the majority of the positive findings were perception based. These summaries demonstrate a need for further outcomes evidence to validate policies.
