A cost analysis of inpatient compared with outpatient prostaglandin E2 cervical priming for induction of labour: results from the OPRA trial.

Objective: To compare the costs of inpatient (usual care) with outpatient (intervention) care for cervical priming for induction of labour in women with healthy, low-risk pregnancies who are being induced for prolonged pregnancies or for social reasons.

Methods: Data from a randomised controlled trial at two hospitals in South Australia were matched with hospital financial data. A cost analysis comparing women randomised to inpatient care with those randomised to outpatient care was performed, with an additional analysis focusing on those who received the intervention.
