    "abstract": "Compare complication rates of second trimester induction for abortion or fetal demise for patients with and without prior cesarean delivery.\nRetrospective cohort study examining induction for abortion or fetal demise for pregnancies from 14w0d to 23w6d gestation at 2 urban academic medical centers from 2009 to 2019. Exclusion criteria included preterm labor or cervical insufficiency, neonatal interventions, or if misoprostol was not the primary induction method. Complication rates were compared between those with no prior, 1 prior, and 2 or more (2+) prior cesarean deliveries. Complications analyzed were retained placenta, failed induction, infection, hemorrhage, blood transfusion, uterine rupture, intensive care unit admission, death, and readmission. Secondary analysis included cumulative misoprostol dosages and complete abortion rate within 24 hours.\nOf 520 patients, 411 patients had no prior cesarean delivery, 77 had 1 prior cesarean delivery, and 32 had 2+ prior cesarean deliveries. Eleven patients had a prior vertical uterine incision. About 26.5% of all patients received mifepristone. The 2+ prior cesarean delivery group was significantly older (35 vs 32 vs 32, p < 0.001) and more likely to be induced for fetal demise (62.5 vs 41.56 vs 39.17%, p\u00a0=\u00a00.04). Both cesarean groups were more likely to be obese (58.62 vs 49.35 vs 34.26%, p\u00a0=\u00a00.003). Patients with 2+ prior cesarean deliveries were more likely to experience uterine rupture (6.25 vs 0 vs 0%, p\u00a0=\u00a00.004), and require ICU admission (6.45 vs 1.3 vs 0.49%, p\u00a0=\u00a00.02). Secondary analysis outcomes were similar. Logistic regression showed patients with 2+ prior cesarean deliveries were more likely to experience a complication than those with 1 prior (adjusted odds ratio [aOR] 2.71, confidence interval [CI] 1.09-6.86, p\u00a0=\u00a00.03) or 0 prior cesarean deliveries (aOR 3.00, CI 1.30-7.02, p\u00a0=\u00a00.01). Patients with 1 prior or no prior cesarean deliveries had a similar risk of experiencing a complication (aOR 1.11, CI 0.64-1.89, p\u00a0=\u00a00.7).\nMost patients with prior cesarean deliveries can safely undergo induction in the second trimester for abortion or fetal demise. Patients with 2+ prior cesarean deliveries had a higher rate of at least 1 complication when compared to those with one or no prior cesarean delivery, despite similar misoprostol dosages and rates of complete abortion.\nThis large 10-year retrospective study examines the impact of prior cesarean delivery on the safety of second trimester induction. While second trimester labor induction abortion remains an option for all patients, specialized counseling for patients with 2 or more prior cesarean deliveries may be warranted.",
