Obstetricians’ perspectives on trial of labor after cesarean (TOLAC) under the two-child policy in China: a cross-sectional study

Abstract

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. Conclusion 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.

The 12-year Experience - A Retrospective and Hospital-based Study of Gestational Trophoblastic Neoplasia in the Northwest of China

“…GTN patients in the northwest of China were treated at different hospitals rather than in designated disease centers. Before patients getting GTN, the two-child policy in China that introduced in recent years may be a reason for increased parity among patients in 2015-2020 group [27]. After disease remission, scienti c guidance regarding effects of chemotherapy regimen on pregnancy and timing of another pregnancy may increase opportunities for patients to successfully become pregnant.…”

Evaluation of factors that predict the success rate of trial of labor after the cesarean section

“…However, currently, concerns about the risks of TOLAC have left only a small number of obstetricians and pregnant women to conduct TOLA C willingly. Therefore, effective measures need to be taken to help obstetricians predict and reduce the risks associated with TOLAC [ 10 ].…”

The urological complications of vaginal birth after cesarean (VBAC) – a literature review

“…The regulatory organizations are trying to compensate by promoting vaginal birth after cesarean section (VBAC), which is in its infancy in less developed countries. Achieving this goal is hampered by several restrictions on the reluctance of both physicians and patients regarding VBAC [ 9 ]. Despite this, VBAC was considered by many patients a good method to avoid repeated cesarean deliveries [ 10 ].…”

“…Trial of labor after cesarean (TOLAC) is a planned or tried VBAC, being a safe option for many women in trying to reduce cesarean birth after cesarean (CBAC) [ 9 ].…”
