OBJECTIVES: To assess symptoms in older intensive care unit (ICU) survivors and determine whether post-ICU frailty identifies those with the greatest palliative care needs. DESIGN: A prospective cohort study. SETTING: Urban tertiary care hospital and community hospital. PARTICIPANTS: Medical ICU survivors of mechanical ventilation aged 65 and older (N = 125). MEASUREMENTS: Baseline measurements of the Edmonton Symptom Assessment Scale (ESAS), categorized as mild (0-3), moderate (4-6), and severe (7-10), and the frailty phenotype were made during the week before hospital discharge. Functional recovery was defined as a return to a Katz activity of daily living dependency count less than or equal to the prehospitalization dependency count within 3 months. In the last 29 participants recruited, we made additional assessments of fatigue and ESAS both at baseline and 1 month after discharge. RESULTS: Fatigue was the most-prevalent moderate to severe symptom (74%), followed by dyspnea (53%), drowsiness (50%), poor appetite (47%), pain (45%), depression (42%), anxiety (36%), and nausea (17%). At 1-month follow-up, there were no significant differences in the proportions of participants with moderate to severe symptoms. Each increase in baseline ESAS fatigue severity category was associated with 55% lower odds of functional recovery (odds ratio = 0.45, 95% confidence interval = 0.24-0.84), independent of age, sex, comorbidities, and critical illness severity. Frail participants had a higher median baseline total ESAS symptom distress score (34, interquartile range (IQR) 23-44) than nonfrail participants (13, IQR 9-22) (P < .001). CONCLUSION: Older ICU survivors have a high burden of palliative care needs that persist 1 month after discharge. Fatigue is the most-prevalent symptom and may interfere with recovery. Post-ICU frailty may be a useful trigger for palliative care consultation and a treatment target.
