Among an average of 2,210 facilities reporting per month (range, 1,341-2,791), most (56%) were Health Centre IIs. There were seasonal peaks in stockouts of ACTs and RDTs, with small peaks in December through February and sharp peaks in June through September. At the national level, we observed a significant increase in the monthly ACT (S=474, p&amp;lt;0.001; Sen’s slope=+0.59) and RDT (S=444, p&amp;lt;0.001; Sen’s slope=+0.616) stockouts over the study period. Monthly ACT stockouts increased significantly across all facility levels, with Health Centre IIs having the largest increase (S=472, p&amp;lt;0.001; Sen’s slope=+0.697) while general hospitals reported the smallest increase (S=198, p=0.026; Sen’s slope=+0.201). Among 136 districts, the number of districts experiencing ACT stockouts increased steadily, from 5 in 2017 to 85 in 2022.
