PurposeWe sought to measure inpatient healthcare utilization among U.S. Veteran Affairs beneficiaries surviving sepsis hospitalization, and to examine how post-sepsis utilization varies by select patient characteristics.
Materials and methods
Retrospective cohort study of 26,561 Veterans who survived sepsis hospitalization in 2009. Using difference-in-differences analysis, we compared changes in healthcare utilization in one year before and one year after sepsis hospitalization by Veteran age, illness severity, and recent nursing facility use.
Median days in a healthcare facility increased from 5 to 10. Veterans with recent nursing facility use spent a median 65 days (or 86% of days alive) in a healthcare facility in the year after sepsis. Older age, greater illness severity, and recent nursing home use were each associated with spending more days, and a greater proportion of days alive, in a healthcare facility during the year after sepsis. However, none of these characteristics was associated with a greater rise in utilization after sepsis.
Veterans surviving sepsis experience high rates of post-sepsis mortality and significant increases in healthcare facility use. Recent nursing facility use is strongly predictive of greater post-sepsis healthcare utilization.
