The problem
Intervention: The Routine Immunisation Wheel, a low-cost visual tool to improve knowledge of vaccination schedules, benefits, and session sites among caregivers and frontline health workers
Who it was tested with: 384 caregivers per arm and more than 60 frontline health workers (ANMs, ASHAs, Anganwadi Workers, mobilizers) in Madhya Pradesh, India.
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.
"Using a mixed-methods approach, we conducted a quasi-experimental pilot comparing intervention and control districts with 384 caregivers per arm and more than 60 FLWs" with "independent samples t-tests for group comparisons, chi-square tests for proportions". The study used baseline-endline measurements in both intervention and control groups to evaluate the effectiveness of the visual tool on immunisation knowledge outcomes.
Quasi-experimental design without randomisation; conducted as a pilot in one state only; no data on whether knowledge gains translated to improved immunisation coverage rates or long-term sustainability of tool use
