Severity and management of drug-drug interactions in acute geriatric patients.

Background: Previous studies have investigated the prevalence of drug-drug interactions (DDIs) among the elderly in different care settings, but data describing the frequency and management of DDIs among acute geriatric patients appear to be absent.

Objective: The aim of this study was to investigate the severity and interdisciplinary management of DDIs in patients admitted to an acute geriatric ward.

Methods: The study was conducted at Oslo University Hospital, Norway, over a period of 19 weeks in 2010/11.
