Abstract

The obstetrical landscape in the United States has changed over the past several decades, during which there has been a decline in the number of operative vaginal deliveries performed. Procedural cases of obstetrics and gynecology residents are tracked in the Accreditation Council for Graduate Medical Education database, with a minimum requirement of 15 operative vaginal deliveries before graduation. Nowadays, it is unknown whether the decreasing numbers of operative vaginal deliveries are affecting the delivery case volume and experience of obstetrics and gynecology residents. This study aimed to analyze the trends in the number and route of obstetrical deliveries, including operative vaginal deliveries, performed by graduating obstetrics and gynecology residents in the United States as logged within the Accreditation Council for Graduate Medical Education database. The Accreditation Council for Graduate Medical Education case log data were examined for graduating obstetrics and gynecology residents between 2003 and 2019. Delivery case volume numbers for spontaneous vaginal delivery, cesarean delivery, forceps-assisted vaginal delivery, and vacuum-assisted vaginal delivery were extracted and analyzed over time using linear regression. To compare the variability in logged cases, residents at the 70th percentile for number of cases logged were compared with residents at the 30th percentile for number of cases logged for each delivery type (spontaneous vaginal delivery, cesarean delivery, forceps-assisted vaginal delivery, and vacuum-assisted vaginal delivery). Overall, obstetrical delivery data for 20,268 obstetrics and gynecology residents were collected from 2003 to 2019. Over this period, the mean number of spontaneous vaginal deliveries significantly decreased over time by 20% from 320.8±138.7 to 256.1±75.6 (slope, -2.6; P<.001); however, no significant difference was noted in the reported cesarean delivery cases, with an 8% increase from 191.8±80.1 to 206.8±69.7 per graduating resident (slope, 0.136; P=.873). Notably, the mean reported cases of forceps-assisted vaginal deliveries decreased by 75% from 23.8±21.9 to 6±6.8 per graduating resident (slope, -0.851; P<.001). Similarly, the mean logs of vacuum-assisted vaginal delivery decreased by 37% from 23.8±17.1 to 15±9.5 (slope, -0.542; P<.001). The ratio of reported resident case logs comparing the volume at the 70th percentile with the volume at the 30th percentile demonstrated a significant decrease over time for spontaneous vaginal delivery (slope, -0.015; P<.001), cesarean delivery (slope, -0.015; P<.001), and vacuum-assisted vaginal delivery (slope, -0.033; P<.001) but was significantly increased for forceps-assisted vaginal delivery (slope, 0.07, P=.0065). In the reported Accreditation Council for Graduate Medical Education case logs, we identified that the reported number of obstetrical deliveries performed by obstetrics and gynecology residents in the United States is changing, with a significant decline recognized from 2003 to 2019 in logged numbers of spontaneous vaginal deliveries, vacuum-assisted vaginal deliveries, and forceps-assisted vaginal deliveries, without a difference in reported cesarean delivery cases per graduating resident. Furthermore, substantial variation is seen among resident volume nationwide, with the difference in high- and low-volume resident forceps-assisted vaginal delivery experience increasing over time. Awareness of these data should notify the Accreditation Council for Graduate Medical Education and educators about reasonable targets, increased need for simulation, and new ways to teach all modes of deliveries effectively in all residency programs.
