Trial of labour versus elective repeat caesarean section: a cost-effectiveness analysis
Summary
For women with a prior caesarean section, choosing a trial of labour for subsequent births is 30% less expensive than an elective caesarean section. This cost-effectiveness holds true as long as fewer than 68% of women require an emergency caesarean section.
Area of Science:
- Obstetrics and Gynaecology
- Health Economics
- Public Health
Background:
- Women with a previous caesarean section face a critical decision for future pregnancies: elective repeat caesarean section or trial of labour.
- Understanding the comparative health system costs and birth outcomes of these two pathways is crucial for informed clinical and policy decisions.
Purpose of the Study:
- To compare the birth outcomes and health system costs associated with elective caesarean section versus trial of labour for subsequent births in Australia.
- To determine the cost-effectiveness threshold for trial of labour success rates.
Main Methods:
- Utilisation of Australian hospital data to analyse birth outcomes and associated health system costs.
- Comparative economic analysis of two birth pathways: elective caesarean section and trial of labour.
Main Results:
- Trial of labour is 30% less expensive overall compared to elective caesarean section, despite higher costs in cases of emergency caesarean section.
- Trial of labour remains the most cost-effective strategy provided that the rate of emergency caesarean section following a trial of labour is below 68%.
Conclusions:
- Trial of labour presents a more cost-effective option than elective caesarean section for women with a prior caesarean section.
- Accurate data on a wider spectrum of costs and outcomes is essential for robust conclusions regarding the optimal birth pathway.
