Análisis de costo efectividad de la vitamina A en niños menores de 5 años en Colombia / Cost-effectiveness analysis (CEA) regarding vitamin A in children aged less than 5 years-old in Colombia

Objetivo evaluar la costo-efectividad relativa del uso de vitamina a en los niños menores de 5 años en la disminución de eventos de diarrea, malaria y la mortalidad, bajo la perspectiva del sistema de salud colombiano (SGSSS). Materiales y Métodos se construyó unárbol de decisión con muertes evitadas como desenlace. Las probabilidades se extrajeron de la literatura y los costos de fuentes oficiales. El umbral de costo-efectividad fue tres veces el producto interno bruto (PIB) per cápita colombiano de 2012. Se realizaron análisis de sensibilidad determinísticos, probabilísticos y curva de aceptabilidad. Resultados En una cohorte de cien mil niños, la administración de vitamina a, frente no hacerlo, representaría un ahorro en costos de atención médica de $ 340.306.917, debido a que reduce el número de eventos de diarrea (4.268) y de malaria (76), así como los casos en los que se requiere hospitalización. En todos los análisis de sensibilidad se obtuvo un ahorro para el sistema. Conclusión Dentro del sistema de salud colombiano, la suplementación con vitamina a para niños menores de 5 años, comparado con no hacerlo, es la estrategia menos costosa y más efectiva (dominante).

Objective Evaluating the relative cost-effectiveness of using vitamin A in children aged less than 5-years-old regarding the reduction of events involving diarrhoea, malaria and mortality from the Colombian health-related social security system (CHSSS). Materials and Methods A decision tree was constructed, using deaths averted as outcome. Probabilities were taken from the pertinent literature and costs from official sources. The cost-effectiveness threshold was three times greater than the per capita Colombian gross domestic product (GDP) in 2012. Probabilistic and deterministic sensitivity analyses were made and cost effectiveness acceptability curves were drawn. Results Providing a cohort of 100,000 children with vitamin A (as opposed to not doing so) would represent a saving regarding medical attention costs of $ 340,306,917 due to the number of events involving diarrhea (4,268) and malaria (76), having become reduced, as well as cases requiring hospitalization. A saving for the CHSSS was consistently obtained in sensitivity analysis. Conclusion Providing vitamin supplements for children aged less than 5 years-old would seem to be the least costly and most effective (dominant) strategy for the CHSSS, i.e. compared to not doing so).

Cost of vitamin A and iron supplementation to "at risk" population.

This is a cost descriptive study which estimates the cost of providing iron and vitamin A supplementation through the primary health care system in India. The norms for the primary health care workers were taken as per national norms. The costs included the proportionate cost of the building, workers' salary and the cost of the supplements. The total cost of providing iron supplementation through the PHC was estimated at Rs. 43,800. The cost per beneficiary for adult folifer was Rs. 3.60, for paediatric folifer was Rs. 2.90 and for syrup folifer, it was Rs. 15.50. The overall cost of providing iron and folic acid supplements to the "at risk" population was estimated as Rs 4.40 per beneficiary per year. The cost of vitamin A supplementation to under three through the PHC system was estimated at Rs. 3.20 per beneficiary per year. Both iron as well as vitamin A supplementation through the PHC system appear to be low cost interventions.
