ENTRINGER, Aline Piovezan; PINTO, Márcia; DIAS, Marcos Augusto Bastos  e  GOMES, Maria Auxiliadora de Souza Mendes. Cost-effectiveness analysis of spontaneous vaginal delivery and elective cesarean for normal risk pregnant women in the Brazilian Unified National Health System. Cad. Saúde Pública [online]. 2018, vol.34, n.5, e00022517.  Epub 10-Maio-2018. ISSN 0102-311X.  https://doi.org/10.1590/0102-311x00022517.

The purpose of this study was to conduct a cost-effectiveness analysis of spontaneous vaginal delivery and elective cesarean (with no clinical indication) for normal risk pregnant women, from the perspective of the Brazilian Unified National Health System. An analytical decision model was developed and included the choice of delivery mode and clinical consequences for mothers and newborns, from admission for delivery to hospital discharge. The reference population consisted of normal risk pregnant women with singleton, at-term gestations in cephalic position, subdivided into primiparas and multiparas with prior uterine scar. Cost data were obtained from three public maternity hospitals (two in Rio de Janeiro, one in Belo Horizonte, Minas Gerais State, Brazil). Direct costs were identified with human resources, hospital inputs, and capital and administrative costs. Effectiveness measures were identified, based on the scientific literature. The study showed that vaginal delivery was more efficient for primiparas, at lower cost (BRL 1,709.58; USD 518.05) than cesarean (BRL 2,245.86; USD 680.56) and greater effectiveness for three of the four target outcomes. For multiparas with prior uterine scar, repeat cesarean was cost-effective for the outcomes averted maternal morbidity, averted uterine rupture, averted neonatal ICU, and averted neonatal death, but the result was not supported by probabilistic sensitivity analysis. For maternal death as the outcome, there was no difference in effectiveness, and labor showed the lowest cost. This study can contribute to the management of perinatal care, expanding measures that encourage adequate delivery according to the population’s characteristics.
