This study operationalizes the evaluation of provider payment reforms and outpatient health insurance (i.e., KONSULTA+ or the Comprehensive Outpatient Benefit Package) expansion under the UHC Act (2019). The Department of Health (DOH) and PhilHealth plan to pilot Disease Related Groups (DRGs) implementation and outpatient benefit package (which uses a capitation payment system) in select provinces in the country under the CATCH Program by the third to the fourth quarter of 2023. Hence, assessing whether these provider payment reforms will impact health sector goals (i.e., improve efficiency, quality, and equity of healthcare services), at least in pilot sites, is critical. The evaluation will be the basis of expanding the provider payment reforms nationwide. The UHC Act of 2019 mandates the DOH and PhilHealth to provide evidence of the effectiveness of these reforms to Congress by 2025 (Republic of the Philippines 2019:11223).
