Intervention: Community engagement interventions to improve routine child immunisation
Who it was tested with: Children in low-income and middle-income countries.
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 included experimental and quasi-experimental impact evaluations of community engagement interventions considering outcomes related to routine child immunisation in LMICs," with systematic review and meta-analysis methodology that examined effectiveness across 94 studies. The design allows for causal inference about intervention effectiveness across diverse settings and implementations.
The meta-analysis did not provide a single pooled effect size figure in the extracted text, and outcomes were primarily measured through caregiver report rather than objective verification records. Heterogeneity among studies and specific intervention components were not detailed in the provided excerpt.
