Labor induction is among the common and widely practiced obstetric interventions aiming at achieving vaginal delivery. However, cesarean section (CS) delivery incidences have been reported following its use. This study aimed at determining the prevalence and risk factors for caesarean delivery following labor induction among women who gave birth at a tertiary hospital in north-Tanzania. A hospital-based retrospective cohort study was designed using maternally-linked data from Kilimanjaro Christian Medical Centre (KCMC) birth registry among women who gave birth to singleton babies from the year 2000 to 2015. All induced deliveries done in this period were studied. Women with multiple pregnancy, missing information on delivery mode and those with history of CS delivery were excluded. Relative risk and 95% Confidence Interval for risk factors for CS delivery following labor induction were estimated using log-binomial regression models. Robust variance estimation was used to account for repeated deliveries from the same subject. A total of 1088 deliveries were analysed. The prevalence of CS following labour induction was 26.75%. Independent risk factors for CS delivery were; primiparity (RR = 1.46; 95% CI: 1.18–1.81), high birthweight (RR =1.28; 95% CI: 1.02–1.61), post-term pregnancy (RR = 1.45; 95% CI: 1.09–1.93), and urban residence (RR =1.29; 95%CI: 1.05–1.58). In patients undergoing labor induction, primiparity, high birthweight, post dates and urban residence were found to associate with an elevated risk of caesarean delivery. Assessment of these factors prior to labor induction intervention is warranted to reduce adverse pregnancy outcomes associated with emergency caesarean delivery.

坦桑尼亚北部一家三级医院引产后剖腹产的患病率和危险因素:一项回顾性队列研究(2000-2015年)

引产是旨在实现阴道分娩的常见且广泛实践的产科干预措施。然而,剖宫产(CS)的分娩发生率据报道使用后。这项研究旨在确定在坦桑尼亚北部北部一家三级医院分娩的妇女引产后剖腹产的患病率和危险因素。使用来自乞力马扎罗山基督教医学中心(KCMC)出生登记处的母体相关数据,设计了一项基于医院的回顾性队列研究,研究对象为2000年至2015年间单胎婴儿的妇女。在此期间,所有诱导分娩均得到了研究。排除了多胎妊娠,分娩方式信息缺失和有CS分娩史的妇女。使用对数二项回归模型估算了引产后CS分娩的危险因素的相对风险和95%置信区间。稳健的方差估计用于解释同一受试者的重复分娩。总共分析了1088架飞机。引产后CS的患病率为26.75%。CS传播的独立危险因素为;初产(RR = 1.46; 95%CI:1.18–1.81),高出生体重(RR = 1.28; 95%CI:1.02-1.61),足月妊娠(RR = 1.45; 95%CI:1.09–1.93)和城市居民(RR = 1.29; 95%CI:1.05-1.58)。在接受引产的患者中,发现初产,高出生体重,约会和城市居住与剖腹产的风险增加有关。
