The problem
Intervention: Community-based midwife continuity of care (CBMCOC) model
Who it was tested with: Pregnant women living in ethnically diverse and socially disadvantaged areas of South London between 2018 and 2020, including subgroups of ethnic minority women and those in highly deprived areas.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"We conducted a prospective cohort study using the eLIXIR, Born in South London, maternity-child data linkage" and "Propensity score matching (1:4) was used to account for differences between CBMCOC and standard care cohorts and control for confounding bias." This quasi-experimental approach with comparison groups and statistical matching provides stronger evidence than pre-post designs, though not as robust as randomised trials.
Observational design using propensity score matching rather than randomisation; potential for unmeasured confounding; limited detail on CBMCOC model components; outcomes limited primarily to preterm birth.
