In a large cohort study of 12,854 ICU survivors in Germany, patients who survived respiratory sepsis (RS) – mostly from bacterial pneumonia – had significantly worse long-term outcomes than those who survived SARS-CoV-2 sepsis (SS) or influenza-associated sepsis (IS).

One year after discharge, RS survivors showed markedly higher risks of death, rehospitalization, new cognitive impairment, and nursing-care dependency compared to the viral-sepsis groups.

RS patients were older, had more comorbidities, longer hospital stays, and far higher rates of septic shock (27% vs. 4–8% in viral cohorts), underscoring greater illness severity.

Even after adjustment, respiratory sepsis emerged as an independent driver of poor long-term prognosis, with survivors particularly prone to persistent fatigue, cognitive decline, and loss of independence.

The authors emphasize the urgent need for specialized post-ICU follow-up and rehabilitation programs tailored to bacterial/respiratory sepsis survivors, who appear to suffer more long-term damage than their viral-sepsis counterparts despite similar acute presentations.

Limitations include the use of claims data and applicability mainly to pre-Omicron COVID-19 waves.
