We compared total charges for obstetric care at a major teaching hospital and faculty group practice with those at 3 nonteaching centers in western Washington. The patients were all enrollees of an employee-based health maintenance organization. Charges were used as a proxy for costs and included all outpatient, inpatient, and physician charges. In the teaching system, patients were cared for by faculty and house staff; in the nonteaching settings, they received care from private physicians. No significant differences in total charges were found between the teaching and the nonteaching settings for all deliveries ($4,652 [N = 90] versus $4,530 [N = 335], P greater than .5). In the teaching setting, vaginal deliveries were slightly more expensive ($4,178 [n = 75] versus $3,768 [n = 250], P = .15), as were cesarean deliveries ($7,024 [n = 15] versus $6,771 [n = 85], P greater than .5). The rate of cesarean deliveries was lower in the teaching setting (17% versus 25%, P = .10), partially accounting for the similarity in total charges. The length of stay was similar in the teaching hospital (3.29 versus 3.14 days, P greater than .5). We conclude that the academic medical center as a total system of care can provide obstetric care as cost-effectively as nonteaching systems under the constraints of prepaid care.
