OBJECTIVES: High rates of preterm birth and limited access to evidence-based, cost-effective interventions unsupported by fragmented and unsystematic financing hinder child mortality reduction locally. We aimed to cost a full spectrum of care for prematurity complications, to develop a comprehensive benefit package to ensure financial risk protection through the National Health Insurance Program. METHODS: Two frameworks of standard care algorithms and outcomes were developed in two birthweight categories (500-<1,500g; 1500-<2500g) and for women at <37 weeks using literature- and expert-panel-based data. Valuation of cost components was done. Gross costing was used for accommodation-related costs, where general service components were aggregated; modified microcosting for clinical-related costs, with patient and hospital specific costs identified; and modified bottom-up approach for patient-specific unit costs per service. Component costs from  11 hospitals and 3 maternity clinics surveyed nationwide were entered into a configured spreadsheet. RESULTS:
