![]() TRST/VIP fitted well but their discrimination power was poor (area under the curve=0.49 and 0.46, respectively). ![]() The activities for daily living that declined most frequently were toilet use, grooming, dressing and bathing. Basal/12-month BI was 85/70, respectively. Results: Nine hundred and fifty-eight patients from the 1632 included survived during follow-up. Development of the new score was performed by dividing into a derivation cohort (constructing the index by logistic regression), and a validation cohort (in which calibration/discrimination of the index were tested). Accuracy of TRST/VIP was assessed by calibration/discrimination tests. Functional decline was defined as loss of ≥20 points on Barthel’s index (BI). Methods: Prospective 12-month follow-up study of PPs from 36 hospitals. Our objective was to assess accuracy of the Triage Risk Screening Tool (TRST), the Variable Indicative of Placement risk (VIP) and to develop a specific functional prognostic index adjusted to this population in a multicenter cohort of hospital-based PP. Background: Little is known about the fitness of the available tools in predicting functional decline of polypathological patients (PPs).
