Abstract

Background The clinical frailty scale (CFS) score has been validated as a predictor of adverse outcomes in community-dwelling older people. Older people are at a higher risk of sepsis and have a higher mortality rate. However, the association of frailty on outcomes in patients with sepsis has not been completely examined. Objective This study evaluated the association between CFS and outcomes in patients with sepsis. Design This was a multicenter prospective cohort substudy. Settings and participants The study included 37 emergency departments from across Japan. The patients (age ≥16 years) were included in this study if they had suspected infection at an emergency department during December 2017-February 2018. Outcome measure and analysis The primary outcome was 28-day mortality, stratified by the CFS score categories. The secondary outcomes were the duration of hospital stay, number of ICU-free days (ICUFDs) and number of ventilator-free days (VFDs). Main results A total of 917 patients were included. The median age was 79 years. The CFS score was associated with an increased risk of 28-day mortality and with a higher likelihood of long-term hospital stay and short-term VFDs and ICUFDs. Multivariate logistic regression analysis indicated that the CFS score was a predictor of 28-day mortality [odds ratio (OR), 1.26; 95% confidence interval (CI), 1.11-1.42]. Conclusions This study reported that in patients with suspected sepsis in the emergency department, frailty may be associated with poor prognosis and length of hospital stay.
