Improved Infant Outcomes with Group Prenatal Care in Puerto Rico

OBJECTIVES: To evaluate the impact of group prenatal care (Centering Pregnancy) on the rate of Preterm Birth (PTB) and low birth weight. Women were enrolled into Centering Pregnancy (Transformación Prenatal) if they fell in the category of poverty, and had at least one risk for PTB according to known risk factors for low birth weight or PTB. METHODS: Mother’s age, parity, risk factors, prenatal/delivery complications, infants’ Gestational Age (GA), birth weight, Apgar scores, delivery route, indications for delivery, and use of Neonatal Intensive Care Unit (NICU) were abstracted from charts of mothers who received group or traditional care at the University Hospital in San Juan, PR. RESULTS: More infants were born at term if the mothers received Centering Pregnancy. The mean birth weight and gestational age of the infants were higher (6.59 vs. 6.33 lbs. and 37.8 vs. 36.8 weeks) than for those in traditional care. Centering Pregnancy also had lower rates of preterm birth (27.7% vs. 34.1%) and births earlier than 31 weeks (2.8% vs. 9.9%). All were statistically significant (P<0.05). CONCLUSIONS: We successfully implemented group prenatal care (Centering Pregnancy) for the first time in PR in a complex environment: tertiary care hospital with a high-risk prenatal clinic. Despite having known risk factors for preterm birth, the mothers in Centering Pregnancy had better outcomes. In an environment of adverse determinants of health, the program was effective in reducing the odds for adverse infant outcomes early in life and demonstrating that innovative models of health care can improve such outcomes.
