OBJECTIVES: This study aimed to estimate the frequency of hospitalizations due to @entity4091 ( @entity4091 ) and to describe their clinical characteristics by sex and age group. METHODS: Descriptive population-based cross-sectional study of hospital admissions due to @entity4091 from 2003 to 2013 among residents in the Autonomous Community of Madrid. Sex, age, comorbidities, length of stay and outcomes were collected and described. Crude and age-adjusted cumulative incidence rates, and stratified by sex and age, were estimated. Robust Poisson regression analysis was used to calculate the incidence rate ratios by age group. RESULTS: 2039 hospitalizations were identified (51.0% in @entity1 ). Complicated @entity4091 caused 48.7% of them (50.9% in @entity1 ). The hospitalization rate was 2.98/100,000 @entity1 -years and 7.19/1000 cases of @entity4091 in primary care. Both rates were significantly higher in @entity1 , except in the extreme age groups. An immunosuppression-associated comorbidity was identified in 32.8% of the cases and was less common in @entity1 >=  75 years of age. The median length of stay was 6 days, and in-hospital mortality was 1.4%. CONCLUSIONS: Hospitalization rates due to @entity4091 were higher in @entity1 and increased with age. In two out of every three cases, a comorbidity that potentially caused immunosuppression could not be identified. These cases could benefit from vaccination.
