We advise the implementation of a structured, repeated medication review with the essential roles of pharmacist, physician and nurse, into daily practice. This work was supported and funded by the Netherlands Organisation for Health Research and Development (ZonMw). Netherlands Trial Register (NTR3569).

Objectives: To evaluate the effect of the PROPER intervention in nursing home residents with dementia on the prevalence of psychotropic drug use and neuropsychiatric symptoms. Design: A cluster-randomized controlled design with two parallel groups (intervention versus usual care) and assessments at 0, 6, 12, and 18 months. Setting: Thirty-one dementia special care units within 13 long-term care organizations in the Netherlands. Participants: Three hundred eighty nursing home residents with dementia Intervention: The PROPER intervention consisted of a structured and repeated multidisciplinary medication review, supported by education and continuous evaluation. Measurements: Prescriptions of antipsychotics, antidepressants, anxiolytics, and hypnotics, and occurrence of neuropsychiatric symptoms. Results: The prescription of any type of psychotropic drugs increased in the intervention group, and decreased in the control group, with an estimated difference of 3.9 percentage points per 6 months (p = 0.01). Effects for the individual drug groups were minor (differences of 1.6 percentage points and below per 6 months) and not statistically significant. The occurrence of neuropsychiatric symptoms remained stable in both the intervention and control groups during the follow-up of 18 months. Conclusions: The PROPER intervention failed to demonstrate effectiveness in reducing the prevalence of psychotropic drugs. It may be interesting to enrich the intervention with components that address personal attitudes and communication between nursing home professionals, not only with respect to the prescription of psychotropic drugs, but also to neuropsychiatric symptoms. The study has been registered in The Netherlands Trial Register (NTR3569).

The minority of the PD use was fully appropriate. The results imply that PD use for NPS in dementia can be improved; the appropriateness should be optimized with a clinical focus on the appropriate indications, evaluations, and therapy duration.

BackgroundNeuropsychiatric symptoms are highly prevalent in nursing home patients with dementia. Despite modest effectiveness and considerable side effects, psychotropic drugs are frequently prescribed for these neuropsychiatric symptoms. This raises questions whether psychotropic drugs are appropriately prescribed. The aim of the PROPER (PRescription Optimization of Psychotropic drugs in Elderly nuRsing home patients with dementia) II study is to investigate the efficacy of an intervention for improving the appropriateness of psychotropic drug prescription in nursing home patients with dementia.Methods/designThe PROPER II study is a multi-center cluster randomized controlled, pragmatic trial using parallel groups. It has a duration of eighteen months and four six-monthly assessments. Six nursing homes will participate in the intervention and six will continue care as usual. The nursing homes will be located throughout the Netherlands, each participating with two dementia special care units with an average of fifteen patients per unit, resulting in 360 patients. The intervention consists of a structured and repeated multidisciplinary medication review supported by education and continuous evaluation. It is conducted by pharmacists, physicians, and nurses and consists of three components: 1) preparation and education, 2) conduct, and 3) evaluation/guidance. The primary outcome is the proportion of patients with appropriate psychotropic drug use. Secondary outcomes are the overall frequency of psychotropic drug use, neuropsychiatric symptoms, quality of life, activities of daily living, psychotropic drug side effects and adverse events (including cognition, comorbidity, and mortality). Besides, a process analysis on the intervention will be carried out.DiscussionThis study is expected to improve the appropriateness of psychotropic drug prescription for neuropsychiatric symptoms in nursing home patients with dementia by introducing a structured and repeated multidisciplinary medication review supported by education and continuous evaluation.Trial registrationNetherlands Trial Registry (NTR): NTR3569.
