Objetivo Valorar el impacto economico del Gas Natural Domiciliario -GND- como tecnologia sanitaria sobre la enfermedad respiratoria asociada al humo de biomasa en localidades del caribe colombiano. Metodos Tres estudios combinados: a) carga de enfermedad respiratoria asociada al uso de combustibles de biomasa; b) costos de la enfermedad (Infeccion Respiratoria Aguda -IRA- y Enfermedad Pulmonar Obstructiva Cronica-EPOC); y c) analisis de costo efectividad del GND para reducir morbilidad por enfermedades respiratorias. Resultados En las localidades se esperarian anualmente 498 (477-560) casos de IRA que generaria 149 (119-196) hospitalizaciones, 6 (4-10) muertes y 7 291 (5 746 -9 696) AVAD. Tambien se esperarian 459 (372-684) casos de EPOC, 138 (93-239) hospitalizaciones, 11 (5-26) muertes y 1 500 (973-2 711) AVAD. Los costos de esta carga de enfermedad en ausencia del GND son anualmente de 5,2 (3,8-8,3) millones de dolares. De estos, la mayoria son costos de EPOC (cerca del 85 %). Los costos por IRA y EPOC, luego de instalado el GND, ascienden a 3,5 (2,5-5,7) millones de dolares. Los costos evitados serian 1,6 (1,2-2,6) millones de dolares, (30 % de los costos de la carga). El costo efectividad incremental de introducir el GND seria un poco mas de 56 (22-74) mil dolares por muerte evitada y entre 43 y 66 dolares evitar un AVAD. Conclusiones Frente a la no intervencion, la instalacion del GND resulta ser una tecnologia costo efectiva para la reduccion de las enfermedades respiratorias asociadas al consumo de combustibles de biomasa. Palabras Clave: Gas natural, neumonia, EPOC, costo efectividad (fuente: DeCS, BIREME). The cost-effectiveness of installing natural gas as a sanitary alternative for rural communities on the Colombian Caribbean coast burning biomass fuels Objective Evaluating the economic impact of natural gas as a sanitary technology regarding respiratory disease associated with indoor air pollution in rural localities on the Colombian Caribbean coast. Methods Three studies were carried out: the burden of respiratory disease was evaluated (acute lower respiratory infection-ALRI and chronic obstructive pulmonary disease - COPD), disease costs were studied and the cost effectiveness of natural gas was analysed in terms of reducing indoor air pollution. Results Without natural gas in these localities, it would be expected that 498 (477560) cases of ALRI per year would lead to 149 (119-196) hospitalisations, 6 (4-10) deaths and 7 291 (5,746-9,696) disability adjusted life years (DALY) annually. Furthermore, it is expected that 459 (372-684) cases of COPD per year would lead to 138 (93-239), hospitalisations, 11 deaths (5-26) and 1 500 (973-2 711) DALY annually. Annual disease burden cost was 5,2 (3,8-8,3) million dollars before installing domiciliary natural gas (DNG); most of such cost arose from COPD (around 85 %). ARI and COPD costs after installing DNG would rise to 3,5 (2,5-5,7) million dollars; avoided costs would be 1,6 (1,2-2,6) million dollars, (30 % of disease burden cost without DNG). The incremental cost-effectiveness (ICER) of installing DNG would be 56 (22-74) thousand dollars per life saved and ICER per DALY saved would be 43-66 dollars. Conclusion DNG is a sanitary technology which reduces the burden of indoor air pollution-associated respiratory diseases arising from burning biomass fuel in rural localities in a cost-effective way. Key Words: Natural gas, COPD, cost effectiveness (source: MeSH, NLM).
