Vaginal delivery: how does early hospital discharge affect mother and child outcomes? A systematic literature review

Abstract

Abstract Background There is an international trend to shorten the postpartum length of stay in hospitals, driven by cost containment, hospital bed availability and a movement toward the ‘demedicalization’ of birth. The aim of this systematic literature review is to determine how early postnatal discharge policies from hospitals could affect health outcomes after vaginal delivery for healthy mothers and term newborns. Methods A search for systematic reviews, meta-analyses, and primary studies was carried out in OVID MEDLINE, Embase, CINAHL, Econlit and the Cochrane Library (Cochrane Database of Systematic Reviews, DARE and HTA databases). The AMSTAR checklist was used for the quality appraisal of systematic reviews. The quality of the retrieved studies was assessed by the Cochrane Collaboration’s tools. The level of evidence was appraised using the GRADE system. Results Seven RCTs and two additional observational studies were found but no comprehensive economic evaluation. Despite variation in the definition of early discharge, the authors of the included studies, concerning early discharge and conventional length of stay, reported no statistical difference in maternal and neonatal morbidity, maternal and neonatal readmission rates, infant mortality, newborn weight gain, neonatal hyperbilirubinemia, or breastfeeding rates. The authors reported conflicting results regarding postpartum depression and competence of mothering, ranging from no difference according to length of stay to better results for early discharge. The level of evidence of the vast majority of outcomes was rated as low to very low. Conclusions Because of the lack of robust clinical evidence and full economic evaluations, the current data neither support nor discourage the widespread use of early postpartum discharge. Before implementing an early discharge policy, Western countries with longer length of hospital stay may benefit from testing shorter length of stay in studies with an appropriate design. The issue of cost containment in implementing early discharge and the potential impact on the current and future health of the population exemplifies the need for publicly funded clinical trials in such public health area. Finally, trials testing the range of out-patient interventions supporting early discharge are needed in Western countries which implemented early discharge policies in the past.
