Surgeon Distress as Calibrated by Hours Worked and Nights on Call

BACKGROUND: The relationships of working hours and nights on call per week with various parameters of distress among practicing surgeons have not been previously examined in detail. STUDY DESIGN: More than 7,900 members of the American College of Surgeons responded to an anonymous, cross-sectional survey. The survey included self-assessment of their practice setting, a validated depression screening tool, and standardized assessments of burnout and quality of life. RESULTS: There was a clear gradient between hours and burnout, with the prevalence of burnout ranging from 30% for surgeons working <60 hours/week, 44% for 60 to 80 hours/week, and 50% for those working >80 hours/week (p < 0.001). When correlated with number of nights on call, burnout exhibited a threshold effect at >= 2 nights on call/week (<= 1 nights on call/week 30%; >= 2 nights on call/week, 44% to 46%; p < 0.0001). Screening positive for depression rate also correlated strongly with hours and nights on call (both p < 0.0001). Those who worked >80 hours/week reported a higher rate of medical errors compared with those who worked <60 hours/week (10.7% versus 6.9%; p < 0.001), and were twice as likely to attribute the error to burnout (20.1% versus 8.9%; p = 0.001). Not surprisingly, work and home conflicts were higher among surgeons who worked longer hours or had >= 2 nights on call. A significantly higher proportion of surgeons who worked >80 hours/week or had >2 nights on call/week would not become a surgeon again (p < 0.0001). CONCLUSIONS: Number of hours worked and nights on call per week appear to have a substantial impact on surgeons, both professionally and personally. These factors are strongly related to burnout, depression, career satisfaction, and work and home conflicts. (J Am Coll Surg 2010;211: 609-619. (C) 2010 by the American College of Surgeons)
