Methodological Evaluation of Community Health Centre Systems in Tanzania: A Randomized Field Trial on Adoption Rates

Community health centers in Tanzania are pivotal for delivering healthcare services to underserved populations. However, their effectiveness and sustainability depend on community uptake and system adoption. A randomized field trial was conducted in three regions of Tanzania. Participants were randomly assigned to either an intervention group (receiving enhanced services) or a control group (standard services). Data on service utilization and satisfaction were collected using standardised surveys. Thirty percent of participants adopted the new system within six months, with higher adoption rates observed in urban areas compared to rural settings. The randomized field trial methodology effectively captured community health centre system adoption rates, providing a robust framework for future evaluations and policy implementation. Policy makers should prioritise funding and infrastructure development in underserved regions to enhance service utilization. Continuous monitoring of the adopted systems is recommended to ensure sustainability. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
