ABSTRACT

RESUMEN Objetivo Evaluar los costos de las terapias de rehidratación oral (TRO) y de rehidratación nasogástrica (TRN) comparadas con la terapia de rehidratación endovenosa (TRE) para corregir la deshidratación por diarrea en niños. Metodología Análisis de minimización de costos desde la perspectiva del Sistema de Salud colombiano comparando TRO (seguida de TRN ante falla de la TRO), con la TRE. El horizonte temporal fue la duración de la rehidratación. La medida de efectividad se extrajo de una revisión sistemática de literatura. Para determinar costos, se construyó un caso típico y un árbol de decisiones, a partir de revisión de guías e historias clínicas, validado con expertos. Los costos unitarios se obtuvieron de bases de datos colombianas. Costos fueron calculados en pesos colombianos (COP) y dólares americanos (USD). Se realizaron análisis de sensibilidad de una y dos vías. Resultados La TRO y la TRE son similares en efectividad para prevenir hospitalización y lograr rehidratación. En el caso base, el costo de la TRO fue $91,221COP (40.5 USD) y para TRE $112,944COP (50.14USD), es decir, un ahorro de $21,723 COP (9.64 USD). En los análisis de sensibilidad por regímenes de aseguramiento y complejidad del hospital, la TRO suele ser la estrategia menos costosa. Discusión Ambas intervenciones son similares en efectividad, pero la TRO, seguida de TRN ante falla de la primera resulta menos costosa que la TRE. La TRO es recomendable como primera opción para corregir la deshidratación. Deberían continuarse esfuerzos por implementar TRO y TRN en los servicios de salud en Colombia.(AU)


ABSTRACT Objective To evaluate the costs of oral rehydration therapy (ORT) and nasogastric rehydration therapy (NRT) compared with intravenous rehydration therapy (IRT) to treat dehydration in children under 5 years of age with diarrhea. Methodology Cost-minimization analysis from the perspective of the Colombian Health System, comparing ORT, (followed by NRT when ORT fails), with IRT. The time horizon was the duration of rehydration. The effectiveness measure was obtained from a systematic review of the literature. To determine costs, a typical case was created based on current guidelines and medical records; this case was validated by experts. Unit costs were obtained from Colombian databases and were provided in Colombian pesos (COP) and US dollars (USD) for 2010. One- and two-way sensitivity analyzes were performed. Results ORT and ERT are similarly effective to prevent hospitalization and to achieve rehydration. In the base case, the expected cost of ORT was $91,221 COP (40.5 USD) and for IRT was $112,944 COP ($50.14 USD), saving $21,723 COP ($9.64 USD) per case. In the sensitivity analyzes by health insurance and hospital level, ORT is often the least costly strategy. Discussion Both interventions are similarly effective, but ORT, followed by NRT when ORT fails, is less costly than IRT. ORT is recommended as the first option to treat dehydration since it is effective and less expensive. Efforts should be continued to implement TRO and NRT in the health services of Colombia.(AU)

ABSTRACT

Objectives: To determine the relative cost-effectiveness of zinc supplementation for the treatment of acute diarrhoea in children under five years in Colombia. Methods: Cost-effectiveness analysis from the perspective of the Colombian Health System. We evaluated standard treatment with addition of zinc versus standard treatment without zinc supplement for children from birth to five years. The time horizon was the duration of the diarrhoea. Effectiveness information was extracted from a Cochrane systematic review and Colombian databases and observational studies. Identification and measurement of resource use was based in clinical guidelines, protocols and expert opinion. Unit costs were obtained from Colombian tariff manuals. We performed deterministic sensitivity analysis to assess the impact of changes in the cost and effectiveness of the strategies on the results of the model. Results: The average treatment cost of one diarrhoea episode in Colombia is USD $40.77 using standard treatment, and USD $32.96 with zinc supplementation, a reduction of $7.81 USD. Additionally, zinc supplementation is more effective than standard treatment without zinc: it reduces diarrhoea-related mortality and incidence of persistent diarrhoea. The results are sensitive to changes in the probability of hospitalization and persistent diarrhoea, but conclusions do not change substantially. Conclusions: Zinc for the treatment of acute diarrhoea is a highly cost-effective strategy from the perspective of the Colombian Health System. It is more cost-effective in children with higher risk of persistent diarrhoea and hospitalization.
