          Abstract

          OBJECTIVE: To estimate the health and economic burden of rotavirus gastroenteritis in hospital and outpatient settings in eight Latin American and Caribbean countries (Argentina, Brazil, Chile, Dominican Republic, Honduras, Mexico, Panama, and Venezuela). METHODS: An economic model was constructed using epidemiological data from published articles, national health administration studies, and country-specific cost estimates. For each of the eight countries, the model estimated the rotavirus outcomes for the 2003 birth cohort during the first five years of life. The main outcome measures included health care costs, transportation costs, lost wages, and disease burden expressed in disability-adjusted life years. Estimates were expressed in 2003 US dollars. All future costs and disability-adjusted life year estimates were discounted at a rate of 3%. Sensitivity analyses evaluated the impact of specific variables on the medical cost of treating rotavirus. RESULTS: For every 1 000 children born during 2003 in the eight Latin American and Caribbean countries studied here, we estimated that rotavirus gastroenteritis would result in an average of 246 outpatient visits, 24 hospitalizations, 0.6 deaths, and US\(7 971 in direct medical costs during their first five years of life. The incidence of rotavirus-associated outpatient visits and the cost of outpatient visits were predicted to have the largest impact on the total medical cost per child. CONCLUSIONS: Rotavirus gastroenteritis is likely to result in substantial disease and economic burden to health systems in Latin American and Caribbean countries, and the foreseeable burden should be an important consideration in evaluating the cost-effectiveness of vaccination.

          OBJETIVO: Estimar la carga económica y de morbilidad de la gastroenteritis por rotavirus en hospitales y servicios ambulatorios de ocho países de América Latina y el Caribe (Argentina, Brasil, Chile, Honduras, México, Panamá, República Dominicana y Venezuela). MÉTODOS: Se elaboró un modelo económico a partir de datos epidemiológicos de artículos publicados, estudios de autoridades sanitarias nacionales y los estimados de costos específicos de cada país. El modelo calculó las consecuencias de la infección por rotavirus en los primeros cinco años de vida de la cohorte de nacidos en 2003 en cada uno de los ocho países estudiados. Las principales medidas de valoración fueron los costos de la atención sanitaria, los costos de transportación, los salarios perdidos y la carga de morbilidad expresada en años de vida ajustados por discapacidad. Los estimados se expresaron en dólares estadounidenses del año 2003. Se empleó una tasa de descuento de 3% para los cálculos de costos y años de vida ajustados por discapacidad de los años siguientes. El impacto de las variables específicas sobre los costos clínicos del tratamiento de la infección por rotavirus se realizó mediante análisis de sensibilidad. RESULTADOS: Se estimó que durante los primeros cinco años de vida, la gastroenteritis por rotavirus provoca en promedio 246 consultas externas, 24 hospitalizaciones, 0,6 muertes y gastos médicos directos por US\) 7 971,00 por cada 1 000 niños nacidos en 2003 en los ocho países estudiados de América Latina y el Caribe. Se prevé que la frecuencia de visitas médicas asociadas con la infección por rotavirus y los costos por consultas externas tengan el mayor impacto en los costos clínicos totales por niño. CONCLUSIONES: La gastroenteritis por rotavirus puede representar una considerable carga económica y de morbilidad para los sistemas sanitarios de los países de América Latina y el Caribe. Se debe prestar una especial atención a la carga previsible al evaluar la efectividad en función del costo de la vacunación contra rotavirus.

          Safety and efficacy of an attenuated vaccine against severe rotavirus gastroenteritis.

          The safety and efficacy of an attenuated G1P[8] human rotavirus (HRV) vaccine were tested in a randomized, double-blind, phase 3 trial. We studied 63,225 healthy infants from 11 Latin American countries and Finland who received two oral doses of either the HRV vaccine (31,673 infants) or placebo (31,552 infants) at approximately two months and four months of age. Severe gastroenteritis episodes were identified by active surveillance. The severity of disease was graded with the use of the 20-point Vesikari scale. Vaccine efficacy was evaluated in a subgroup of 20,169 infants (10,159 vaccinees and 10,010 placebo recipients). The efficacy of the vaccine against severe rotavirus gastroenteritis and against rotavirus-associated hospitalization was 85 percent (P<0.001 for the comparison with placebo) and reached 100 percent against more severe rotavirus gastroenteritis. Hospitalization for diarrhea of any cause was reduced by 42 percent (95 percent confidence interval, 29 to 53 percent; P<0.001). During the 31-day window after each dose, six vaccine recipients and seven placebo recipients had definite intussusception (difference in risk, -0.32 per 10,000 infants; 95 percent confidence interval, -2.91 to 2.18; P=0.78). Two oral doses of the live attenuated G1P[8] HRV vaccine were highly efficacious in protecting infants against severe rotavirus gastroenteritis, significantly reduced the rate of severe gastroenteritis from any cause, and were not associated with an increased risk of intussusception.

            Econometric estimation of country-specific hospital costs

            Information on the unit cost of inpatient and outpatient care is an essential element for costing, budgeting and economic-evaluation exercises. Many countries lack reliable estimates, however. WHO has recently undertaken an extensive effort to collect and collate data on the unit cost of hospitals and health centres from as many countries as possible; so far, data have been assembled from 49 countries, for various years during the period 1973–2000. The database covers a total of 2173 country-years of observations. Large gaps remain, however, particularly for developing countries. Although the long-term solution is that all countries perform their own costing studies, the question arises whether it is possible to predict unit costs for different countries in a standardized way for short-term use. The purpose of the work described in this paper, a modelling exercise, was to use the data collected across countries to predict unit costs in countries for which data are not yet available, with the appropriate uncertainty intervals. The model presented here forms part of a series of models used to estimate unit costs for the WHO-CHOICE project. The methods and the results of the model, however, may be used to predict a number of different types of country-specific unit costs, depending on the purpose of the exercise. They may be used, for instance, to estimate the costs per bed-day at different capacity levels; the "hotel" component of cost per bed-day; or unit costs net of particular components such as drugs. In addition to reporting estimates for selected countries, the paper shows that unit costs of hospitals vary within countries, sometimes by an order of magnitude. Basing cost-effectiveness studies or budgeting exercises on the results of a study of a single facility, or even a small group of facilities, is likely to be misleading.
