背景:随着中国的生育政策从独生子女一对夫妇调整为普遍的二胎一对夫妇,有越来越多的妇女在先前的剖宫产(CS)后再次怀孕.进行选择性重复CS(ERCS)已被视为理所当然,因此已成为中国CS率提高的主要原因。促进CS(TOLAC)后分娩试验可以降低CS率,而不会影响分娩结果。本研究旨在调查中国产科医生对TOLAC的看法,以及根据二胎政策向有CS病史的孕妇推荐TOLAC的决策相关因素。
方法:2018年5月至7月进行了横断面调查。二元逻辑回归用于确定与产科医生向有CS病史的孕妇推荐TOLAC的意向相关的因素。独立变量包括社会人口统计学因素和对TOLAC的看法(TOLAC的选择标准,TOLAC选择标准的基础,以及关于推广TOLAC的感知挑战)。
结果:共调查了426名产科医生,有效率≥83%。结果显示,31.0%的产科医生无意向有CS病史的孕妇推荐TOLAC。他们的决定与有CS病史的孕妇及其家人对接受TOLAC缺乏信心有关(比值比[OR]=2.31;95%CI:1.38-1.38);产科医生对有CS病史的孕妇使用TOLAC的安全性的不确定性(OR=0.49;95%CI:0.27-0.96),以及对不良分娩结果引起的医疗诉讼的担忧(OR=0.14;95%CI:0.07-0.31)。关于执行TOLAC的主要报告挑战是缺乏明确的指导方针来预测或避免与TOLAC相关的风险(83.4%)。产科医生对有CS病史的女性使用TOLAC的安全性不确定(81.2%),孕妇不愿接受与TOLAC相关的风险(81.0%)或对ERCS的需求(80.7%),以及孕妇及其家人对接受TOLAC的缺乏信心(77.5%)或理解(69.7%)。
结论:一部分中国产科医生不打算向有CS病史的孕妇推荐TOLAC。这种现象与产科医生对TOLAC安全性的担忧以及孕妇及其家人对TOLAC的感知态度密切相关。需要采取有效措施来帮助产科医生预测和降低与TOLAC相关的风险。明确规定TOLAC的适应症,改善劳动管理,并在中国推广TOLAC。此外,有必要对TOLAC进行公共卫生教育,以提高有CS病史的孕妇及其家人对TOLAC的了解,并改善他们与产科医生在共同决策方面的互动。
BACKGROUND: As the birth policy has been adjusted from one-child-one-couple to universal two-child-one-couple in
China, there is an increasing number of women undergoing a second pregnancy after a previous cesarean section (CS). Undertaking an elective repeat CS (ERCS) has been taken for granted and has thus become a major contributor to the increasing CS rate in
China. Promoting trial of labor after CS (TOLAC) can reduce the CS rate without compromising delivery outcomes. This study aimed to investigate Chinese obstetricians\' perspectives regarding TOLAC, and the factors associated with their decision-making regarding recommending TOLAC to pregnant women with a history of CS under the two-child policy.
METHODS: A cross-sectional survey was carried out between May and July 2018. Binary logistic regression was used to determine the factors associated with the obstetricians\' intention to recommend TOLAC to pregnant women with a history of CS. The independent variables included sociodemographic factors and perceptions regarding TOLAC (selection criteria for TOLAC, basis underlying the selection criteria for TOLAC, and perceived challenges regarding promoting TOLAC).
RESULTS: A total of 426 obstetricians were surveyed, with a response rate of ≥83%. The results showed that 31.0% of the obstetricians had no intention to recommend TOLAC to pregnant women with a history of CS. Their decisions were associated with the perceived lack of confidence regarding undergoing TOLAC among pregnant women with a history of CS and their families (odds ratio [OR] = 2.31; 95% CI: 1.38-1.38); obstetricians\' uncertainty about the safety of TOLAC for pregnant women with a history of CS (OR = 0.49; 95% CI: 0.27-0.96), and worries about medical lawsuits due to adverse delivery outcomes (OR = 0.14; 95% CI: 0.07-0.31). The main reported challenges regarding performing TOLAC were lack of clear guidelines for predicting or avoiding the risks associated with TOLAC (83.4%), obstetricians\' uncertainty about the safety of TOLAC for women with a history of CS (81.2%), pregnant women\'s unwillingness to accept the risks associated with TOLAC (81.0%) or demand for ERCS (80.7%), and the perceived lack of confidence (77.5%) or understanding (69.7%) regarding undergoing TOLAC among pregnant women and their families.
CONCLUSIONS: A proportion of Chinese obstetricians did not intend to recommend TOLAC to pregnant women with a history of CS. This phenomenon was closely associated with obstetricians\' concerns about TOLAC safety and perceived attitudes of the pregnant women and their families regarding TOLAC. Effective measures are needed to help obstetricians predict and reduce the risks associated with TOLAC, clearly specify the indications for TOLAC, improve labor management, and popularize TOLAC in
China. Additionally, public health education on TOLAC is necessary to improve the understanding of TOLAC among pregnant women with a history of CS and their families, and to improve their interactions with their obstetricians regarding shared decision making.
