The problem
Intervention: Residential stability (not relocating; used as comparison group to understand the effect of relocation)
Who it was tested with: Children aged 9-59 months in Dhaka, Bangladesh; 3,795 recently relocated (< 12 months) and 4,713 residentially stable (> 24 months).
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Using vaccination cards with maternal recall, full vaccination was 80% among recently relocated children (n=3795) and 85% among residentially stable children (n=4713; χ2=37.2, p<0.001)... After adjusting for demographic and socioeconomic characteristics, recently relocated children were less likely to be fully vaccinated (prevalence ratio [PR] 0.97; 95% CI 0.95 to 0.99; p=0.016) and to have visited a qualified medical provider for ARI (PR 0.88; 95% CI 0.84 to 0.93; p<0.001)." This uses a comparison group design with statistical adjustment, making it an experimental-tier study examining the association between relocation and reduced health service use.
Cross-sectional design cannot establish causation. Uses maternal recall for some vaccination data. Cannot determine whether relocation itself causes lower utilisation or confounding factors explain both.
