About

Nursing home residents are among the frailest patient groups with a high number of co-morbidities and a high use of medicines. Inappropriate polypharmacy (i.e. often overprescribing) is one of the major problems in the nursing home population increasing the number of adverse drug reactions, falls, hospital admissions, mortality as well as having an impact on health care utilization. Multidisciplinary medication reviews have a great potential to reduce inappropriate medication use. The purpose of this study is to determine the efficacy of a multidisciplinary medication review model focussing on discontinuing inappropriate medication in a cluster randomized controlled trial in 600 nursing home residents. The primary outcome measure is the difference in proportion of residents who successfully discontinued medication between intervention and control group after four months. Secondary outcome measures will be the drug burden index, adverse drug withdrawal events related to the discontinued medication, death, referral to hospitals and quality of life.

Multidisciplinary medication review

Experimental group

Description:

The multidisciplinary medication review consists of 5 steps: Step #1: Assessing patients' experiences and preferences regarding medicine use en assessing their medical history, allergies and lab results Step #2: Drug reviewing to assess contra-indicated medication and duplicate medication using consensus criteria e.g. START STOPP Beers criteria Step #3: Reflecting on results of drug reviewing Step #4: Setting up a pharmacotherapeutical action plan Step #5: Execution of pharmacotherapeutical action plan

Treatment:

Procedure: Multidisciplinary medication review

usual care

No Intervention group

Description:

Includes medication safety monitoring and ad hoc medication reviews on clinical indication that differ in quality and frequency, but no standardized multidisciplinary multistep medication reviews in the way as described for the intervention arm
