Abstract

Background: A fast and simple tool is needed to test for the risk of mortality and rehospitalization in older patients. Objective: The aim of this study was to construct and validate a prognostic index using specific items from the Comprehensive Geriatric Assessment (CGA) in a large population of older hospitalized adults. Method: This was a prospective study of a 24-month follow-up period, between 2005 to 2008 in 3,043 elderly patients (mean age, 81±6) discharged from three acute geriatric wards in the Marche region of Italy. Baseline predictors of demographics and 25 items from the CGA regarding functional and cognitive status, depression, co-morbidity, social isolation, and quality of life were used to build a summary score, the Hospitalized Older Patient Examination (HOPE) Index. The HOPE index was developed in 1,533 patients and validated in 1,510 consecutively hospitalized patients. Outcome measures were 24-month mortality and rehospitalization. Results: Three risk categories of HOPE based on the best sensitivity and specificity for mortality and rehospitalization were: Low (≤4), moderate (4-8), and high (≥8). Categorizing data across the HOPE index, mortality ranged from 7.9% to 14.5% in the development cohort and 6.2% to 14.0% in the validation cohort, whereas rehospitalization ranged from 68.3% to 79.4% and 69.8% to 79.8%, respectively. Kaplan-Meier survival curves demonstrated that risk for mortality increased with a worsening across the HOPE index (p
