We estimated that ACs in 58% of fokontany were located more than 2 hours from their supporting health facility, and the proportion of fokontany with ACs more than 2 hours away from their assigned supply point was 61%. Reassigning ACs to the closest facility or supply point led to modest improve- ments in those figures (7 and 4 percentage points, respectively). Conclusion: Findings allow visualizing the practical implications of coverage ratios for ACs to assess whether current demands are realistic. The physical access between ACs and the health sys- tem warrants significant attention due to challenges in transport and logistics. Analyses are timely to inform the Ministry of Public Health’s strategic thinking in the context of the development of the National Strategic Plan on Strengthening Community Health.
