Epidemiología de las hospitalizaciones por tuberculosis en España: análisis del conjunto mínimo básico de datos 1999-2009 / Epidemiology of hospitalizations for tuberculosis in Spain: analysis of minimum data set 1999-2009

INTRODUCCIÓN: El conjunto mínimo básico de datos es una base clínico-administrativa sobre altas hospitalarias, de mucha utilidad en el nivel autonómico como fuente complementaria a la vigilancia. Existen escasos estudios de ámbito nacional sobre tuberculosis (TB) con el conjunto mínimo básico de datos, por lo que se consideró de interés estudiar las características y la tendencia de los casos hospitalizados por tuberculosis en España. MÉTODOS: Estudio descriptivo de las principales variables del conjunto mínimo básico de datos (sexo, edad, diagnóstico principal, tipo de alta, tiempo de estancia), y análisis de tendencia de las tasas de hospitalización por 100.000 habitantes, según diagnóstico principal, por sexo, grupo de edad y tipo de TB (TB pulmonar [TBP]/TB extrapulmonar [TBEP]), para el periodo 1999-2009 en España. RESULTADOS: Se incluyeron en el estudio 65.609 hospitalizaciones (66% hombres, 66% TBP, 52% entre 15-44 años). La tasa global de TB para todo el periodo fue de 13,93 hospitalizaciones por 100.000 habitantes, siendo de 18,83 en hombres y de 9,18 en mujeres. Las tasas de hospitalización por TBP y TBEP disminuyeron en el periodo 1999-2009 en ambos sexos (TBP en hombres, de 18 a 13, y en mujeres, de 8 a 6; TBEP en hombres, de 4 a 3, y en mujeres, de 3 a 2 hospitalizaciones/100.000 habitantes). En TBP, los niños son los que presentan un menor descenso, y en la TBEP, en hombres hay un incremento en todos los grupos de edad desde 2005. CONCLUSIONES: Los resultados obtenidos son coherentes con los procedentes de la vigilancia. La lenta disminución de las tasas en niños y el aumento de las formas extrapulmonares en hombres podrían estar relacionados con la inmigración, por lo que es necesario mejorar el control de la TB en estos grupos

INTRODUCTION: The National Hospital Discharge Registry is a clinical-administrative database on hospital discharges, which is very useful at a regional level as a complementary source for surveillance. There are few national studies on tuberculosis (TB) using the National Hospital Discharge Registry, thus it was considered of interest to study the characteristics and trends of hospital discharges for TB in Spain. METHODS: A descriptive study was performed using the main variables in the National Hospital Discharge Registry (sex, age, main diagnosis, type of discharge, length of stay), and trend analysis of hospitalization rates per 100,000 population, as well as primary diagnosis, by sex, age group, and type of TB (pulmonary [TBP]/extrapulmonary [TBEP]), for the period 1999-2009 in Spain. RESULTS: A total of 65,609 hospital discharges were included in the study (66% male, 66% TBP, and 52% between 15-44 years). The overall rate of TB for the entire hospitalization period was 13.93 per 100,000 inhabitants, being 18.83 in males and 9.18 in females. The hospitalization rates for TBP and TBEP decreased in the period 1999-2009 in both sexes (TBP in males, from 18 to 13, and in females, from 8 to 6; TBEP in males from 4 to 3, and from 3 to 2 in female hospitalizations/100,000 habitants). In TBP, children are those with a smallest decline, and in TBEP there is an increase in males in all age groups from 2005. CONCLUSIONS: The results are consistent with those from surveillance. The slow decline in rates in children and the increase in extrapulmonary forms in males may be related to immigration, so it is necessary to improve TB monitoring in these groups
