Comparison of obstetric outcome of a primary-care access clinic staffed by certified nurse-midwives and a private practice group of obstetricians in the same community.

OBJECTIVE

The purpose of this study was to compare the obstetric outcome of a primary-care access clinic staffed by certified nurse-midwives, supervised by a private practice group of four obstetricians, with the obstetric outcome of that group's private practice patients.

STUDY DESIGN

A retrospective cohort study was performed. Obstetric outcome of 496 clinic patients was compared with that of 611 private patients in the same community from Aug. 1, 1991, to March 31, 1994.

RESULTS

Obstetric outcomes as measured by (1) perinatal morbidity and mortality, (2) Apgar score, (3) birth weights, and (4) prematurity rates were comparable between the two groups. Significant was the cesarean section rate of 13.1% (10.5% primary) for the clinic patients and 26.4% (18.5% primary) for the private patients and the high percentage (81.8%) of private patients who elected to have repeat cesarean sections.

CONCLUSIONS

(1) Low-income, uninsured, and underinsured women who have access to excellent prenatal care with supervised certified nurse-midwives can have obstetric outcomes similar to women having prenatal care with private obstetricians. (2) Prenatal care with supervised certified nurse-midwives can reduce the cesarean section rate without compromising infant outcome. (3) Utilization of certified nurse-midwives supervised by obstetricians may provide the optimum model for perinatal care, particularly for those women who are at high risk because of social and economic factors and who are currently underserved.
