This document is a letter published in the journal Intensive Care Medicine. The authors conducted a study to determine the association between sepsis in intensive care unit (ICU) patients and long-term mortality and causes of death. They analyzed data from the Swedish Intensive Care Registry from 2005 to 2016 and extracted cause of death registry data until June 2020. The study included 33,994 patients with sepsis and 280,635 patients without sepsis. The results showed that sepsis was associated with a slightly increased risk of death compared to non-sepsis patients, particularly in the elderly age group. Sepsis was also associated with an increased risk of mortality from infectious, tumors, urogenital, and other causes of death. The risk of infectious causes of death in sepsis patients was consistently higher over the 15.5 years of observation. The authors suggest further research on long-term infection prevention for sepsis survivors. [Extracted from the article]
