Impact of specific beers criteria medications on associations between drug exposure and unplanned hospitalisation in elderly patients taking high-risk drugs: A case-time-control study in Western Australia

Abstract

Background: Certain broad medication classes have previously been associated with high rates of hospitalisation due to related adverse events in elderly Western Australians, based on clinical coding recorded on inpatient summaries. Similarly, some medications from the Beers Criteria, considered potentially inappropriate in older people, have been linked with an increased risk of unplanned hospitalisation in this population. Objective: Our objective was to determine whether risk estimates of drug-related hospitalisations are altered in elderly patients taking 'high-risk drugs' (HRDs) when specific Beers potentially inappropriate medications (PIMS) are taken into consideration. Methods: Using ..
