Deprescribing in Newly Admitted Psychogeriatric Nursing Facility Patients.

Abstract

Objective: To determine whether advised changes as a result of structured medication reviews in psychogeriatric patients were implemented and if the implemented changes were maintained.

Design: Prospective cohort study.

Setting: Three nursing facilities in The Netherlands.

Patients, participants: Newly admitted psychogeriatric residents.

Intervention: After admission, a structured medication review was performed by a pharmacist and physician resulting in a treatment plan that was approved by the patient's legal representative and implemented.

Main outcome measure(s): The percentage of advised changes approved (= approval rate) and the percentage of implemented medication changes still present 90 days after approval (= 90-day implementation rate).

Results: A total of 45 patients were included who used a total number of 333 drugs (mean ± standard deviation 7.4 ± 3.3 drugs). Changes were advised to 159 medications used by 42 patients. Of these changes, 150 were approved (approval rate 94.3%). Finally, 105 were implemented, and 89 were still implemented after 90 days (90-day implementation rate 84.8%). Overall, 59.7% of the advised changes concerned deprescribing (stopping or dose reduction). The proportion of advised changes implemented was similar for symptommodifying and risk-modifying drugs, namely, almost 85%. Overall, 55.3% of the recommended changes to deprescribe concerned 10 drug groups.

Conclusion: Medication could be successfully deprescribed from psychogeriatric patients after structured medication reviews performed by pharmacists and nursing facility physicians. More than 50% of the advised changes to deprescribe involved 10 drug groups, which raises the question whether the structured medication review can be performed more efficiently by focusing on the most common problems.
