Objective
To estimate the effect of group prenatal care on perinatal outcomes compared with traditional prenatal care.
Data Sources
We searched MEDLINE through PubMed, EMBASE, Scopus, Cumulative Index of Nursing and Allied Health literature [CINAHL], the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects [DARE], the Cochrane Central Register of Controlled Trials [CENTRAL]) and clinicaltrials.gov.
Methods of Study Selection
We searched electronic databases for randomized controlled trials (RCT) and observational studies comparing group care with traditional prenatal care. The primary outcome was preterm birth. Secondary outcomes were low birthweight (LBW), neonatal intensive care unit (NICU) admission, and breastfeeding initiation. Heterogeneity was assessed using the Q test and I2 statistic. Pooled relative risks (RRs) and weighted mean differences were calculated using random-effects models.
Tabulations, Integration, and Results
Four RCTs and ten observational studies met inclusion criteria. The rate of preterm birth was not significantly different with group care compared with traditional care (11 studies: pooled rates 7.9% vs. 9.3%, pooled RR 0.87; 95% CI 0.70–1.09). Group care was associated with a decreased rate of LBW overall (9 studies: pooled rate 7.5% group care vs. 9.5% traditional care; pooled RR 0.81; 95% CI 0.69–0.96), but not among RCTs (4 studies: 7.9% group care vs. 8.7% traditional care, pooled RR 0.92; 95% CI 0.73–1.16). There were no significant differences in NICU admission or breastfeeding initiation.
Conclusion
Available data suggest that women who participate in group care have similar rates of preterm birth, NICU admission, and breastfeeding.
