Abstract
Background: In 2015, a quality improvement project of childbirth care called Adequate Childbirth Project ("Projeto Parto Adequado"- PPA) was implemented in Brazilian public and private hospitals, aiming to improve the quality of childbirth care and to reduce caesarean sections without clinical indications. The objective of this study is to conduct an economic analysis of two models of care existing in a private Brazilian hospital—the model following the recommendations of the PPA and the standard of care model—in reducing the proportion of caesarean sections. Methods: We conducted a cost-effectiveness analysis using data from one of the private hospitals included in the PPA project. The main outcome was the proportion of caesarean section. We used total cost of hospitalization for women and newborns, from the health care sector perspective, during the length of the observed hospital stay. We did not apply discount rates and inflation rate adjustments due to the short time horizon. We conducted univariate sensitivity analysis using the minimum and maximum costs observed in hospitalizations and variation in the probabilities of caesarean section and of maternal and neonatal complications. Results: 238 puerperal women were included in this analysis. The PPA model of care resulted in a 56.9 percentage point reduction in the caesarean section probability (88.6% vs 31.7%, p < 0.001) with an incremental cost-effectiveness ratio of US$1,237.40 per avoided caesarean section. Women in the PPA model of care also had a higher proportion of spontaneous and induced labor and a lower proportion of early term births. There were no maternal, fetal or neonatal deaths and no significant differences in cases of maternal and neonatal near miss. The cost of uncomplicated vaginal births and caesarean sections was the parameter with the greatest impact on the cost-effectiveness ratio of the PPA model of care. Conclusion: The PPA model of care was cost-effective in reducing caesarean sections in women assisted in a Brazilian private hospital. Moreover, it reduced the frequency of early term births and did not increase the occurrence of severe negative maternal and neonatal outcomes. Plain English summary: Caesarean section is a safe intervention to save the lives of women and newborns. However, it is associated with negative health consequences for women and children in the short, medium and long term. Therefore, its harmful effects can outweigh its benefits when used excessively. Caesarean rates are increasing globally. In Brazil, caesarean section is the most frequent type of birth since 2009. In 2015, a quality improvement project, called "Adequate Childbirth Project" (PPA), was implemented in Brazilian public and private hospitals with the aim of improving the quality of childbirth care and reducing caesarean sections without clinical indications. In this study, we compared the caesarean rate and the hospitalization costs of women assisted in this new model of care and in the standard of care model. The women attended in the PPA model of care had a lower rate of caesarean section (31.7% vs 88.6% in the standard of care model), with no differences in severe negative maternal and neonatal outcomes. Women in the PPA model of care also had a higher frequency of spontaneous or induced labor and a lower frequency of early term births, that is, less than 39 weeks of gestation. The PPA model of care was considered cost-effective, that is, it produced good results for the amount of money spent. This is a promising result for services that face the problem of increasing numbers of caesarean sections and are looking for strategies to improve the quality of childbirth care.
