EVALUATION OF THE CENTERING PREGNANCY PROGRAMS IN TENNESSEE

Assessment Intervention Learning Policy Training

Abstract

The CenteringPregnancy® (CP) program is a group prenatal care model widely implemented in the United States that provides a promising alternative to traditional forms of prenatal care. CP is delivered in 10 group sessions with approximately 8‐12 women per group. Obstetric providers teach women knowledge and skills related to pregnancy, childbirth, and parenting while promoting the growth of support networks among group members. The Centering model is in contrast to traditional prenatal care delivered in ndividual visits with obstetric providers that provide little to no opportunity for women to interact or create support networks with other pregnant women.

The Governor's Office of Children's Care Coordination (GOCCC) funds seven Centering programs in OBGYN clinics, health clinics, and birthing clinics located in various parts of Tennessee. GOCCC requested the Peabody Research Institute (PRI) to prepare a plan for conducting an evaluation of the effectiveness of these programs.

The plan for the evaluation is to compare birth outcomes for women enrolled in CP programs with otherwise equivalent women who have received traditional prenatal care. CP and non‐CP care patients will be compared on four key outcomes: gestational age at birth, birthweight, abnormal newborn conditions, and congenital anomalies. Samples of women in both CP and traditional prenatal care at each site will be drawn and de‐identified data from their medical records will be extracted. Matched CP and traditional care groups will be created and multivariate statistical analyses using propensity scores and additional covariates will be applied to estimate the effects of CP relative to traditional care on the selected outcomes
