Meta-analysis evaluates adoption rates of health surveillance systems in Kenya, suggesting improvements for future evaluations.

This meta-analysis aims to evaluate quasi-experimental studies measuring public health surveillance system adoption in Kenya.
Systematic review of published and grey literature
Extraction of data on design characteristics and adoption metrics
Applied a random-effects meta-regression model for synthesis of adoption proportions
Assessed methodological quality using difference-in-differences and propensity score matching designs.
Pooled adoption rate was 0.42 (95% CI: 0.35 to 0.49) with high variability (I² = 87%)
Difference-in-differences designs showed higher methodological quality scores (p < 0.01)
Frequent omission of fidelity measures for system implementation was noted.

Wanjiku Mwangi (2007) studied this question.
