Duty hour restrictions, ambulatory experience, and surgical procedural volume in obstetrics and gynecology.
BACKGROUND: Prior studies of resident experience in gynecology looked only at the year before and after adoption of ACGME duty hour standards. This study sought to determine whether procedure volume differed after completion of a 4-year residency training program, before and after work hour reform. METHOD: Inpatient and outpatient procedures performed by MetroHealth Medical Center/Cleveland Clinic program residents from 1998 to 2006 were obtained from Annual Reports of Institutional and Resident Experience. Four-year experience before and after duty hour restrictions were compared: hours worked were collected from resident schedules, ambulatory hours and procedures were compared directly, surgical procedures and deliveries were compared using a 2-tailed t test. Data were also obtained for institutional volume changes, and a corrected value, based on the rates of resident cases per available cases, was analyzed. RESULTS: Ambulatory hours worked per resident decreased after implementing work hour reform from 674 to 366 hours. The types of ambulatory and surgical procedures performed varied over time. Overall, basic surgical and obstetrical volume per resident did not change before and after work hour reform (mean before reform, 723 ± 117, mean after reform, 781 ± 200, P = .58 for gynecologic procedures; mean before reform, 611 ± 107, mean after reform, 535 ± 73, P = .18 for basic obstetrics and vaginal and cesarean deliveries). Institutional volume did not change significantly, although the percentage of the institutions' cases performed by residents did decrease for some procedures. CONCLUSION: The ACGME duty hour restrictions do not limit the overall ambulatory or surgical procedural volume in an obstetrics and gynecology residency-training period.
