Abstract: OBJECTIVE: To compare the costs of induction of labor and expectant management in women with preterm prelabor rupture of membranes (PPROM). DESIGN: Economic analysis based on a randomized clinical trial. SETTING: Obstetric departments of eight academic and 52 non-academic hospitals in the Netherlands. POPULATION: Women with PPROM near term who were not in labor 24 h after PPROM. METHODS: A cost-minimization analysis was done from a health care provider perspective, using a bottom-up approach to estimate resource utilization, valued with unit-costs reflecting actual costs. MAIN OUTCOME MEASURES: Primary health outcome was the incidence of neonatal sepsis. Direct medical costs were estimated from start of randomization to hospital discharge of mother and child. RESULTS: Induction of labor did not significantly reduce the probability of neonatal sepsis [2.6% vs. 4.1%, relative risk 0.64 (95% confidence interval 0.25-1.6)]. Mean costs per woman were €8094 for induction and €7340 for expectant management (difference €754; 95% confidence interval -335 to 1802). This difference predominantly originated in the postpartum period, where the mean costs were €5669 for induction vs. €4801 for expectant management. Delivery costs were higher in women allocated to induction than in women allocated to expectant management (€1777 vs. €1153 per woman). Antepartum costs in the expectant management group were higher because of longer antepartum maternal stays in hospital. CONCLUSIONS: In women with pregnancies complicated by PPROM near term, induction of labor does not reduce neonatal sepsis, whereas costs associated with this strategy are probably higher.
