The rate has since plateaued and was 31.9 percent in 2018 (Martin, 2019). Some indications for performing cesarean delivery are shown in Table 30-1. More than 85 percent of these operations are performed for four reasons—prior cesarean delivery, labor dystocia or arrest, fetal jeopardy, or abnormal fetal presentation. The latter three compose the main indications for primary cesarean delivery (Barber, 2011; Boyle, 2013). Efforts to lower these rates are outlined in Safe Prevention of the Primary Cesarean Delivery by the American College of Obstetricians and Gynecologists (2019b).
