RESUMEN
OBJECTIVE: Our purpose was to assess the long-term results of established prematurity prevention programs. STUDY DESIGN: A population cohort of pregnant women from two major urban health care organizations were examined. Rates and cost-benefit analysis of prematurity and patient, system, or physician failures were analyzed. During 1990 1143 pregnant women were prospectively reviewed. RESULTS: A total of 11.8% of the mothers were high risk and responsible for 108 (50.2%) of the preterm deliveries. The preterm birth rate of all enrollees was 4.6%. One percent of the preterm neonates required level III care for complications. The average charge for a 35 week infant was 18 times, and a 36 week infant was five times more costly than a term infant. Patient, physician, and health care system failures occurred at different rates. CONCLUSIONS: This preterm prevention program resulted in low preterm birth rates. Potentially preventable preterm births most often occurred as a result of patient and physician failures.
