Hospitalization rates and prognosis of XXXX with anaphylactic shock in Denmark from 1995 through 2012.

@entity1 @entity56 @entity2021
BACKGROUND: @entity2021 ( @entity2021 ) is an acute, potentially life-threatening @entity56 . There are limited population-based data on changes in the hospitalization rate and prognosis of @entity2021 . OBJECTIVES: We sought to examine the proportion of @entity1 with @entity2021 admitted to an intensive care unit (ICU), the prognosis of @entity2021 , and time trends in @entity2021 hospitalization rates in Denmark from 1995 through 2012. METHODS: We performed a population-based cohort study in Denmark from 1995 through 2012 (cumulative population, 7.1 million) using the Danish National @entity1 Registry and the Danish Civil Registration System. Outcomes included time trends in first-time @entity2021 hospitalization rates, percentage admitted to an ICU, and 30-day mortality overall and stratified by year. RESULTS: We included 6,707 @entity1 with a first-time hospitalization for @entity2021 during 103,747,997 @entity1 -years of observation time. The average @entity2021 hospitalization rate was 64.6 (95% CI, 63.1-66.2) per 1,000,000 @entity1 -years. From 1995 to 2012, the annual @entity2021 hospitalization rate increased more than 2-fold (rate ratio, 2.6; 95% CI, 2.2-3.0). However, the annual hospitalization rate in @entity1 increased 10-fold (rate ratio, 10.75; 95% CI, 5.59-20.67). Only 0.7% of @entity1 died within 30  days after admission (50 deaths), and most fatal @entity2021 cases occurred among @entity1 aged 30  years or older. During the 2005-2012 period, 14.5% of @entity1 hospitalized with @entity2021 were admitted to an ICU. CONCLUSION: The @entity2021 hospitalization rate increased from 1995 to 2012; however, the 30-day mortality was less than 1%.
