AB BACKGROUND: Frailty is a state of vulnerability to diverse stressors. We assessed the impact of frailty on outcomes after discharge in older surgical patients.METHODS: We prospectively followed patients 65 years of age or older who underwent emergency abdominal surgery at either of 2 tertiary care centres and who needed assistance with fewer than 3 activities of daily living. Preadmission frailty was defined according to the Canadian Study of Health and Aging Clinical Frailty Scale as “well” (score 1 or 2), “vulnerable” (score 3 or 4) or “frail” (score 5 or 6). We assessed composite end points of 30-day and 6-month all-cause readmission or death by multivariable logistic regression.RESULTS: Of 308 patients (median age 75 [range 65–94] yr, median Clinical Frailty Score 3 [range 1–6]), 168 (54.5%) were classified as vulnerable and 68 (22.1%) as frail. Ten (4.2%) of those classified as vulnerable or frail received a geriatric consultation. At 30 days after discharge, the proportions of patients who were readmitted or had died were greater among vulnerable patients (n = 27 [16.1%]; adjusted odds ratio [OR] 4.60, 95% confidence interval [CI] 1.29–16.45) and frail patients (n = 12 [17.6%]; adjusted OR 4.51, 95% CI 1.13–17.94) than among patients who were well (n = 3 [4.2%]). By 6 months, the degree of frailty independently and dose-dependently predicted readmission or death: 56 (33.3%) of the vulnerable patients (adjusted OR 2.15, 95% CI 1.01–4.55) and 37 (54.4%) of the frail patients (adjusted OR 3.27, 95% CI 1.32–8.12) were readmitted or had died, compared with 11 (15.3%) of the patients who were well.INTERPRETATION: Vulnerability and frailty were prevalent in older patients undergoing surgery and unlikely to trigger specialized geriatric assessment, yet remained independently associated with greater risk of readmission for as long as 6 months after discharge. Therefore, the degree of frailty has important prognostic value for readmission.Trial registration for primary study ClinicalTrials.gov, no.
