A pharmacist-conducted medication review in nursing home residents: impact on the appropriateness of prescribing

Medication use in nursing homes is often suboptimal. This study investigated the impact of a pharmacist-conducted medication review on the appropriateness of prescribing for Belgian nursing home residents. We conducted a 6-month controlled, non-randomized study in two nursing homes (one intervention and one control nursing home). Sixty-nine residents completed the study in the intervention group (92 residents were included). For the control group, that were 79 residents (100 residents were included). Primary outcome was the appropriateness of prescribing, assessed by a set of validated quality indicators. At baseline, this study detected three main problems associated with the appropriateness of medication use: (i) the Medication Appropriateness Index (MAI) could be improved (continuation of no longer indicated medication was the most common problem), (ii) potential overuse was present in about half of the group, and (iii) potential underuse was present in about 30% of the sample. Despite this, our pharmacist-conducted medication review only modestly improved the appropriateness of prescribing. This may be attributed to the low implementation rate of the pharmacist recommendations
