[Burden of hospitalizations attributable to rotavirus infection in children in the Autonomous Region of Madrid, Spain, period 1999-2000]. / Ingresos hospitalarios atribuibles a rotavirus en niños de la Comunidad de Madrid, período 1999-2000.

OBJECTIVE: To assess rotavirus infection requiring hospitalization in children aged < or = 5 years between 1999 and 2000 in the Autonomous Region of Madrid (Spain). MATERIAL AND METHOD: A retrospective study was conducted, based on the hospital data surveillance system (Conjunto Mínimo Básico de Datos [CMBD]) and on the Spanish national microbiological information system (Sistema de Información Microbiológica [SIM]). CMBD data for all hospital admissions in children aged < or = 5 years with a first-listed diagnosis of intestinal infectious disease (ICD-9-CM codes: 001-009) or non-infective gastroenteritis (ICD-9-CM code: 558) and the reports to the SIM of the major pathogen groups responsible for acute gastroenteritis were analyzed. RESULTS: The annual incidence of hospitalizations for acute gastroenteritis was 69 cases per 10,000 children aged < or = 5 years. Fourteen percent of the 32,541 infections produced by pathogens responsible for acute gastroenteritis reported to the SIM were rotavirus. The estimated annual incidence of hospitalizations due to rotavirus infections was 12 cases per 10,000 children aged (3/4) 5 years. The mean length of stay was 4.0 days, the annual mean number of days of hospitalization was 1,382 days, and the annual cost was 565,907 J. During the rotavirus epidemic months (December and January), the percentage of excess hospitalizations was 67 %. CONCLUSIONS: Rotavirus causes a significant proportion of hospital admissions due to acute gastroenteritis in children aged < or = 5 years in the Autonomous Region of Madrid.

Objetivo Estudiar las hospitalizaciones atribuibles a infecciones por rotavirus en niños de hasta 5 años durante el período 1999-2000 en la Comunidad de Madrid. Material y método Estudio retrospectivo, utilizando como fuentes de información la base de datos hospitalaria Conjunto Mínimo Básico de Datos (CMBD) y el Sistema de Información Microbiológica (SIM). Se analizaron los datos del CMBD correspondientes a hospitalizaciones en niños de hasta 5 años con un diagnóstico principal al alta de enfermedad intestinal infecciosa (códigos CIE-9-MC 001-009) o gastroenteritis no infecciosa (código CIE-9-MC 558) y las notificaciones al SIM de los principales patógenos causantes de gastroenteritis aguda. Resultados La incidencia anual de hospitalizaciones por gastroenteritis aguda fue de 69 casos por 10.000 niños de hasta 5 años. El 14 % de los 32.541 casos de infección producidos por patógenos responsables de gastroenteritis agudas notificados al SIM fueron producidos por rotavirus. La proporción de casos de infección por rotavirus confirmada en laboratorio, extrapolada al número de hospitalizaciones por gastroenteritis aguda da como resultado una incidencia anual de hospitalizaciones atribuibles a rotavirus de 12 casos por 10.000 niños de hasta 5 años. La estancia media hospitalaria fue de 4,0 días, el número medio anual de días de hospitalización fue de 1.382 días y el coste de 565.907 euros. El exceso de hospitalizaciones durante los meses epidémicos para rotavirus (diciembre y enero) fue del 67 %. Conclusiones El rotavirus ocasiona una parte importante de los ingresos hospitalarios por gastroenteritis aguda en niños de hasta 5 años en la Comunidad de Madrid

Fourteen percent of the 32,541 infections produced by pathogens responsible for acute gastroenteritis reported to the SIM were rotavirus. The estimated annual incidence of hospitalizations due to rotavirus infections was 12 cases per 10,000 children aged ¾ 5 years. The mean length of stay was 4.0 days, the annual mean number of days of hospitalization was 1,382 days, and the annual cost was 565,907 J. During the rotavirus epidemic months (December and January), the percentage of excess hospitalizations was 67 %.
