Cost-effectiveness analysis of natural birth and elective C-section in supplemental health

OBJECTIVE  To conduct a cost-effectiveness analysis of natural childbirth and elective C-section for normal risk pregnant women.

METHODS  The study was conducted from the perspective of supplemental health, a health subsystem that finances private obstetric care, represented in Brazil by health plan operators. The reference populations were normal risk pregnant women, who could undergo natural childbirth or elective C-section, subdivided into primiparous and multiparous women with previous uterine scar. A decision analysis model was constructed including choice of delivery types and health consequences for mother and newborn, from admission for delivery to maternity hospital discharge. Effectiveness measures were identified from the scientific literature, and cost data obtained by consultation with health professionals, health plan operators’ pricing tables, and pricing reference publications of health resources.

RESULTS  Natural childbirth was dominant compared with elective C-section for primiparous normal risk pregnant women, presenting lower cost (R$5,210.96 versus R$5,753.54) and better or equal effectiveness for all evaluated outcomes. For multiparous women with previous uterine scar, C-section presented lower cost (R$5,364.07) than natural childbirth (R$5,632.24), and better or equal effectiveness; therefore, C-section is more efficient for this population.

CONCLUSIONS  It is necessary to control and audit C-sections without clinical indication, especially with regard to primiparous women, contributing to the management of perinatal care.
