Cost of Mass Drug Administration for Filariasis Elimination in the province of Sorsogon, Philippines

Objective. Elimination efforts for lymphatic filariasis are underway in the Philippines using mass drug administration (MDA) of diethylcarbamazine and albendazole as one of the main strategies. This cost analysis was done to determine the MDA implementation cost and provide useful information to the control programme on how to best utilize limited resources. Methods. This cost analysis study was conducted in the province of Sorsogon, Philippines in 2004. The study was done from a program perspective. Cost data for 2003 was obtained retrospectively viakey informant interviews and records review using a standardized guide from a multi-country cost analysis study of filariasis elimination programs. Cost figures were classified as either economic or financial costs and expressed in real terms using 2002 as base year. Sensitivity analysis was likewise performed. Results. The total economic cost and cost per person treated with MDA were estimated at US$223,549.55 (Php12,116,385.48) and US$0.40, respectively. The financial costs were less than half ofthe economic costs. The main cost driver was drug distribution. The highest economic and financial costs were incurred at the national (54.5%) and municipal (74.4%) levels, respectively. High variation in costs of MDA activities was observed. Conclusion. This cost analysis provides reasonable estimates which may be used to assist government and other stakeholders in program planning and resource generation for filariasis elimination programs in endemic areas.
