Objectives: The purpose of this study was to compare the mode of delivery and utilization of ambulatory care by women at 60-days postpartum. Methods: Claims data between 1996 and 2003 for a representative sample of 200,000 people randomly selected from all beneficiaries enrolled in Taiwan's NHI program in 2000 were analyzed. A total of 4,995 women were included to estimate ambulatory care utilization 60-days postpartum with the different modes of delivery using a two part model. Results: Women at 60-days postpartum with Caesarean delivery had higher average numbers of outpatient visits and expenditures with shorter intervals between visits, than women with vaginal births. Conclusions: The findings indicated that ambulatory care utilization may increase among women with Caesarean delivery at 60-days postpartum.
