  1. 1. Steven A. Green, Gary D. Poole, PhD Resident work hours: Examining attitudes toward work-hour limits in general surgery, orthopaedics, and internal medicine Surgical and nonsurgical residents who were surveyed about their work hours expressed different opinions about restricting their hours, with surgical residents favoring fewer restrictions than non- surgical residents.
