RESUMO
The objective of this study was to assess the incidence and trends of sepsis hospitalizations in the active component U.S. military over the past decade. Between 1 January 2011 and 31 December 2020, there were 5,278 sepsis hospitalizations of any severity recorded among the active component. The overall incidence was 39.8 hospitalizations per 100,000 person-years (p-yrs). Annual incidence increased 64% from 2011 through 2019, then dropped considerably in 2020. Compared to their respective counterparts, rates were highest among female service members, the oldest and youngest age groups, and recruits. The gap in sepsis hospitalization rates between female and male service members increased over the surveillance period. Pneumonia was the most commonly co-occurring infection, followed by genitourinary infections. Among female service members, genitourinary infections were more commonly diagnosed compared to pneumonia. The most common non-infection co-occurring diagnoses were acute kidney failure and acute respiratory failure. This study demonstrates an apparent sex disparity in sepsis rates and further study is recommended to understand its cause.
