Abstract
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.
