Interventions to improve enablers and/or overcome barriers to seeking care during pregnancy, birthing and postnatal period for women living with vulnerabilities in high-income countries: A systematic review and meta-analysis

Abstract

ObjectiveTo reduce maternal morbidity and mortality, World Health Organization recommendations include: commencing pregnancy care before 12-weeks’, at least eight antenatal and four postnatal visits, and attendance of skilled care at birthing. While lower adherence to the recommendation predominates in low- and middle-income countries, it also occurs in some settings in high-income countries. Globally, various strategies are used to optimise maternity care, in line with these recommendations. This systemic review aimed to determine if enhanced care improves maternal care-seeking, thus improving clinical outcomes for women and babies living with vulnerabilities, in high-income countries. Design, setting and participantsWe searched the Cochrane Central Registers of Controlled Trials and Cochrane Pregnancy and Childbirth, MEDLINE, CINAHL, Proquest Dissertation and Thesis and reference lists of relevant articles. The latest search was performed June 20, 2022. Randomised controlled trials, non-randomised intervention trials and cohort studies comparing effects of interventions designed to increase utilisation of maternal health services with routine care, for women at increased risk of maternal mortality and severe maternal morbidity in high-income countries were included. Two authors selected, extracted, assessed and analysed data. Additional information was sought from study authors. This systematic review and meta-analysis was registered with PROSPERO(CRD42021256811). FindingsNine studies with 5,729 participants were included. Interventions to enhance care significantly increased utilisation of health services, increasing attendance at antenatal classes (Odds Ratio[OR]=15·23, 95%Confidence Interval[CI] 10·73–21·61, p<0·0001) and postnatal visits by 6–8 weeks (OR=2·66, 95%CI 1·94–3·64, p<0·0001), compared to routine care. Infants in the intervention groups were significantly less likely to be: born preterm (OR=0·68, 95%CI 0·56–0·82, p<0·0001); low birthweight (OR=0·78, 95%CI 0·64–0·95, p = 0·01) or; require neonatal intensive care (OR=0·80, 95%CI 0·66–0·96, p = 0·02). Conclusions and Implications for practiceAmong women living with vulnerabilities in high-income countries, interventions to enhance care increases utilisation of maternal health services and improves outcomes.
