Quasi-experimental analysis evaluates cost-effectiveness in district hospital systems, indicating methodological advancements.

The study presents a framework for quasi-experimental cost-effectiveness analysis focusing on district hospital systems.
Employed a difference-in-differences design comparing intervention and control districts.
Collected cost data from hospital financial records.
Measured effectiveness using disability-adjusted life years (DALYs) averted.
Applied a two-way fixed effects model for primary analysis.
The intervention showed a reduction in cost per DALY averted, with a 95% confidence interval of -15% to +5%.
Securing comparable control districts posed significant challenges, highlighting the importance of propensity score matching.
