Interventions to reduce the cesarean delivery rate in a tertiary hospital in China.

ABSTRACT

INTRODUCTION: High cesarean delivery rate has been a global public health concern. This study assesses the effect of medical interventions and societal changes on cesarean delivery rates in a Chinese tertiary hospital. MATERIAL AND METHODS: A retrospective study including all live births ≥34-week gestation between 2008 and 2016 from Guangzhou Women and Children's Medical Center was divided into 5 stages (1) no interventions; (2) patient-controlled epidural analgesia; (3) episiotomy restriction; (4) new labor management; (5) universal two-child policy. An interrupted time series design was used to measure the effect of interventions on overall cesarean rate, primary cesarean rate, maternal and neonatal outcomes. RESULTS: There were 126,609 deliveries including 49,092 cesarean deliveries and 77,517 vaginal deliveries in this period. Overall cesarean delivery rate declined after implementing patient-controlled epidural analgesia, episiotomy restriction and universal two-child policy. Primary cesarean rate decreased after implementing episiotomy restriction. Cesarean rate with previous cesarean dramatically increased, and maternal request cesarean rate decreased gradually. Low Apgar rate (score ≤7 at 5 min) increased after episiotomy restriction and maternal postpartum hemorrhage rate increased after new labor management. CONCLUSIONS: Patient-controlled epidural analgesia, episiotomy restriction and the universal two-child policy showed the most significant effects to reducing the cesarean rate.
