We aim to evaluate potential cost of OP versus inpatient (IP) ripening with transcervical balloon catheters in term patients with unfavorable cervix, and determine the circumstances in which OP ripening could be cost-neutral or even cost-saving. STUDY DESIGN: We created a decision model to compare OP and IP ripening with transcervical balloon catheters in a population of term (>37 weeks) patients with singleton pregnancies, unfavorable cervix, and no contraindications to labor. We performed a cost-minimization analysis and threshold analyses comparing the two
