Prognostic value of symptom burden as a simple patient-reported outcome measure in older patients with heart failure.

This study was performed to investigate the prognostic value of assessing symptom burden using the Edmonton Symptom Assessment System (ESAS) in older patients with Heart Failure (HF). This prospective cohort study was performed in consecutive patients ≥ 60 years old hospitalized with HF at a university hospital between September 2020 and June 2023. ESAS was used to assess nine common symptoms at hospital discharge (total score: 0-90) with higher scores indicating greater severity. The primary outcome was the combined event of HF readmission and all-cause mortality within 6 months. The median ESAS sum score in the study population consisting of 306 patients (median age, 79 years; 54.9% male) was 13 points. The commonly reported moderate-to-severe symptoms were impaired well-being (34.9%), anxiety (27.5%), drowsiness (25.8%), tiredness (24.9%), and depression (22.2%). In multivariate analyses, ESAS sum score was significantly associated with the combined event (adjusted hazard ratio for each 5-point increase, 1.10 (95% confidence interval: 1.04-1.17; p < 0.001). Inclusion of ESAS sum score in the risk model significantly increased both continuous net reclassification improvement (p = 0.028) and integrated discrimination improvement (p = 0.002) for the primary outcome. Comprehensive assessment of symptom burden with ESAS provided additional prognostic information to conventional risk factors in older patients with HF.
