Strengths and Limitations of the Study
Both intervention and comparison districts had some components of CHPS functioning before GEHIP was implemented (about 25% and 35% respectively). By the end of GEHIPs implementation, CHPS covered was about 85% and 55% of the population in intervention and comparison districts respectively. This means the effect of the community-based care may have been underestimated given that both arms of the study had CHPS running. The above notwithstanding, major strengths in this study include its used of data with both intervention and control groups. Also, the use of a rigorous statistical analysis to partial out the group’s differences enhances the quality of evidence generated by this study.
