The Green Bay cesarean section study. II. The physician factor as a determinant of cesarean birth rates for failed labor.

St. Vincent Memorial Hospital, Green Bay, WI.

OBJECTIVE: Our study was designed to develop a profile of specific labor management characteristics generally used by physicians with low versus those with high rates of cesarean sections in the care of nonprogressive labor in nulliparous patients. STUDY DESIGN: A 4-year retrospective data set was used to analyze all patients with nonprogressive labor cared for by 11 board-certified obstetricians and gynecologists practicing full-time at two Green Bay hospitals. Variations in labor management are analyzed and tested for their effect on the rate of cesarean section for failure of labor to progress. RESULTS: Cesarean section in nulliparous women for nonprogressive labor varied from 4.3% of all deliveries in the low group to 12.3% in the high group. Through multivariate analysis we developed a profile of specific labor management characteristics used by physicians with low versus those with high rates of cesarean section. CONCLUSION: These techniques can be used to definitively identify management strategies that result in a decrease in cesarean rates for nonprogressive labor.
