Objective: Preventing the first cesarean delivery (CD) is important as CD rates continue to rise. During the novel coronavirus disease 2019 (COVID-19) pandemic, quality improvement metrics at our hospital identified lower rates of CD. We sought to investigate this change and identify factors that may have contributed to the decrease., Study Design: We compared nulliparous singleton deliveries at a large academic hospital during the COVID-19 pandemic (April through July 2020 during a statewide "stay-at-home" order) to those in the same months 1 year prior to the pandemic (April through July 2019). The primary outcome, mode of delivery, was obtained from the electronic medical record system, along with indication for CD., Results: The cohort included 1,913 deliveries: 892 in 2019 and 1,021 in 2020. Patient characteristics (age, body mass index, race, ethnicity, and insurance type) did not differ between the groups. Median gestational age at delivery was the same in both groups. The CD rate decreased significantly during the COVID-19 pandemic compared with prior (28.9 vs. 33.6%; p  = 0.03). There was a significant increase in the rate of labor induction (45.7 vs. 40.6%; p  = 0.02), but no difference in the proportion of inductions that were elective (19.5 vs. 20.7%; p  = 0.66). The rate of CD in labor was unchanged (15.9 vs. 16.3%; p  = 0.82); however, more women attempted a trial of labor (87.0 vs. 82.6%; p  = 0.01). Thus, the proportion of CD without a trial of labor decreased (25.1 vs. 33.0%; p  = 0.04)., Conclusion: There was a statistically significant decrease in CD during the COVID-19 pandemic at our hospital, driven by a decrease in CD without a trial of labor. The increased rate of attempted trial of labor suggests the presence of patient-level factors that warrant further investigation as potential targets for decreasing CD rates. Additionally, in a diverse and medically complex population, increased rates of labor induction were not associated with increased rates of CD., Key Points: · Primary CD rate fell during COVID-19 pandemic.. · Decrease was driven by more women attempting labor.. · Higher rate of induction without rise in CD rate was found.., Competing Interests: None declared., (Thieme.

Objective: Identify risk factors for poor perineal outcome after operative vaginal delivery., Study Design: A retrospective cohort study was performed including operative vaginal deliveries during 2015 through 2016., Results: Of 529 operative vaginal deliveries, 79 (14.9%) had higher order perineal lacerations and 14 (2.7%) had a wound breakdown. The only significant risk factor for higher order lacerations was chorioamnionitis (aOR 2.2; 95% CI 1.09-4.44). Risk factors for perineal wound breakdown included episiotomy (5.2 vs. 1.2%; p < 0.01), type of operative delivery (5.5% after forceps vs. 1.4% after vacuum; p < 0.01) and postpartum narcotic use. Overall, 9.3% of those using narcotics subsequently had a perineal breakdown as compared to 0.7% (p < 0.01). Narcotic use postpartum remained strongly associated in multivariable logistic regression (aOR 21.29; 95% CI 5.43-83.47). Patients with forceps deliveries, episiotomy, and narcotic use had a 38% risk of breakdown., Conclusion: Women at highest risk of perineal wound breakdown benefit from close follow-up.

Objective: The objective of this study was to compare spontaneous labor outcomes in women undergoing trial of labor after cesarean (TOLAC) and nulliparas to better counsel women., Study Design: A 4-year retrospective cohort. We included women at term in spontaneous labor with vertex singletons and no more than one prior cesarean delivery. In planned secondary analysis, we focused on a subset of women with a prior cesarean and a predicted likelihood of a successful vaginal delivery of 70% or more based on the Maternal-Fetal Medicine Units-vaginal birth after cesarean (VBAC) calculator., Results: Our cohort included 606 TOLACS and 606 nulliparas. Women undergoing TOLAC were more likely to undergo cesarean delivery (25.7 vs. 14.7%; p  < 0.001). Severe maternal hemorrhage (1.5 vs. 0.2%; p  = 0.02) and uterine rupture (1.9 vs. 0.0%; p  < 0.01) were more likely in the TOLAC group. For the subset of women with a predicted likelihood of VBAC of 70% or more, there were no differences in cesarean delivery (16.7 vs. 14.7%; p  = 0.51), maternal, or immediate neonatal complications., Conclusion: Women undergoing TOLAC were more likely to have a cesarean delivery, hemorrhage, or uterine rupture. Those with more than 70% predicted likelihood of VBAC were no more likely to experience these outcomes. These findings help contextualize the risks of TOLAC for women considering this option., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)
