Background: Potentially inappropriate prescriptions (PIPs), associated with adverse drug reactions, hospitalization, and wasteful healthcare spending, are common in elderly patients with comorbidities and multiple drugs.
Objective: Our objective was to develop and validate a new tool to reduce PIPs in a hospitalized geriatric population.
Methods: This was an observational cohort study of two cohorts (development [n = 100 subjects] and validation [n = 449 subjects]) of consecutive patients aged ≥65 years admitted to geriatric wards from April to December 2012.
