Impact of work hour restrictions on resident case experience in an obstetrics and gynecology residency program

Objective: The purpose of this study was to evaluate senior resident case experience before and after enactment of work hour restrictions. Study design: Obstetrics and gynecology experience from 2 postgraduate year 4 classes were evaluated before and after adoption of work hour restrictions. Data were limited to experience obtained during the fourth year of residency. Data were analyzed with the 2-sample t test and Wilcoxon rank sum test, and adjusted for changes in institutional procedural volume. Results: There were significant decreases in resident experience in total abdominal hysterectomy (P = .018); procedures for genuine stress urinary incontinence (P = .004), and hysteroscopy (P = .006): Decreases were seen in resident experience in vaginal birth after cesarean section (P = .011), primary cesarean section (P = .31), and vacuum delivery (P = .007), despite increase in institutional volume. Conclusion: Work hour restrictions have had impact on resident case experience in obstetrics and gynecology. Variance in institutional case numbers account for only some of these changes.
