<p>Quality care outcomes.</p>

We surveyed 22,315 female respondents about 32,743 children <5 who contributed person-time to the analysis. We found no difference in <5 mortality between the before- and under-intervention periods (unadjusted U5MR under intervention was higher at 62.0 versus 56.3 deaths per live births; adjusted hazard ratio 1.03 (95%CI 0.82-1.31). Care-seeking from a qualified healthcare provider for fever, diarrhea, or acute respiratory infection increased (27.0% to 53.7%; p < 0.001); and care-seeking decreased from drugstores (16.4% to 4.9%, p < 0.001) and black-market providers (42.4% to 22.7%, p < 0.001).

Full vaccination among 12–23-month-olds decreased (16.2% in 2018 to 3.5% in 2022 (p < 0.001)) while facility-based delivery increased (41.0% to 57.1% (p < 0.001)). We detected no reduction in under-five mortality during initial implementation of the national CHA program in one Liberian county. Coverage of childhood treatment for high-priority conditions improved, and we observed a shift in care-seeking to trained providers.

These results suggest potential program benefits, but additional interventions, some of which are already underway, will be needed to reduce under-five mortality.</p></div>
