At-Point Clinical Frailty Scale as a Universal Risk Tool for Older Inpatients in Acute Hospital: A Cohort Study
Abstract
BackgroundWhile the Clinical Frailty Scale (CFS) has been extensively validated for predicting health outcomes in older adults, the role of the at-point CFS at the time of examination is unclear. We aimed to examine the ability of the at-point CFS for predicting clinical outcomes of older inpatients.MethodsAs a single-center and prospective cohort study, we enrolled 1,016 older adults who were 65 years or older and were admitted to one of 9 medical or surgical units from May 2021 to September 2021. The associations of the at-point CFS with outcomes of falls, delirium, pressure ulcers, 30-day unplanned readmission and/or emergency department (ED) visits, institutionalization, and a composite outcome were analyzed.ResultsIn the study population (n = 1,016), 26 patients had incident pressure ulcers, 6 patients had falls, 50 patients experienced delirium, and 13 patients died during hospitalization. Also, 37 patients experienced an ED visit and 22 patients had an unplanned readmission within 30 days after discharge. The composite outcome was 1.7% among patients with the CFS < 5 and 28.5% among patients with the CFS ≥ 5. The higher CFS was associated with an increased risk of a fall [odds ratio (OR) 1.74 (1.01–3.01)], pressure ulcers [OR 3.02 (2.15–4.23)], delirium [OR 2.72 (2.13–3.46)], 30-day readmission [OR 1.94 (1.44–2.62)], ED visit [OR 1.81 (1.47–2.23)], death [OR 3.27 (2.02–5.29)], and institutionalization after discharge [OR 1.88 (1.62–2.18)].ConclusionThe at-point CFS assessed in older inpatients can screen high-risk individuals who might experience adverse geriatric conditions and in-hospital outcomes.
