One-year outcomes in sepsis: a prospective multicenter cohort study in Japan

Abstract Background Sepsis is a leading cause of death in intensive care units (ICU). Sepsis survivors are often left with significant morbidity, termed post-intensive care syndrome (PICS), impacting post-sepsis life. The aim was to present detailed data on the prognostic and functional long-term ou...

description Abstract Background Sepsis is a leading cause of death in intensive care units (ICU). Sepsis survivors are often left with significant morbidity, termed post-intensive care syndrome (PICS), impacting post-sepsis life. The aim was to present detailed data on the prognostic and functional long-term outcomes of ICU patients with sepsis in Japan, which is currently lacking and therefore prevents development of targeted solutions. Methods A multicenter prospective study, involving 21 ICUs in 20 tertiary hospitals in Japan, included all consecutive adult ICU patients between November 2020 and April 2022, and diagnosed with sepsis at ICU admission (Sepsis 3). Follow-ups were performed at 3, 6, and 12 months after hospital discharge by telephone and mail. Primary outcome was death or incidence of PICS, defined by any of physical dysfunction (Barthel Index ≤ 90), cognitive dysfunction (Short Memory Questionnaire < 40), or mental disorder (any subscales for anxiety or depression of Hospital Anxiety and Depression Scale ≥ 8, or Impact of Event Scale-Revised ≥ 25). Secondary outcomes included Quality of Life (QOL), employment, and use of hospital, emergency, rehabilitation, and psychiatric services. A multivariable analysis investigated independent factors associated with each dysfunction at each follow-up. Results A total of 339 patients were included (median age 74 [67–82] years, 60% male, 77% septic shock, and a median SOFA of 9 [6–12]). Mortality was 23% at hospital discharge, increasing to 37% at 12 months. The rate of death or those who met PICS Criteria at hospital discharge was 89%, with a death or PICS incidence of 73%, 64%, and 65% at 3, 6, and 12 months, respectively. Limited improvements in QOL and return to work (44%), high rates of hospital readmissions (40%), frequent emergency service usage (31%), and low utilization of rehabilitation and psychiatric services (15% and 7%) were identified over the first year. The incidence of any PICS-related dysfunction was consistently an independent factor for the incidence of the same dysfunction at the following follow-ups. Conclusions This multicenter study identified the distinct realities of post-sepsis life in Japanese ICU patients, highlighting the unique challenges in improving their functions and returning to daily life.
