Improving the appropriateness of psychotropic prescribing for nursing home residents with dementia: an overview of reviews

Objectives: Psychotropic medications are commonly inappropriately prescribed for people with dementia (PwD) residing in nursing homes. This population is often multi-morbid, receiving multiple medications and therefore at an increased risk of mortality. This overview aimed to collate all synthesised quantitative, qualitative, and mixed-method evidence pertaining to the effectiveness of interventions aimed at reducing inappropriate psychotropic prescribing for nursing home residents with dementia; the perceived barriers and facilitators to the implementation of these interventions; and the attitudes and experiences of stakeholders toward prescribing. Method: An overview of reviews was conducted (PROSPERO protocol registration CRD42020187288). Five databases were systematically searched from January 2010 through June 2020, supplemented by grey literature searching. Reviews presenting evidence pertaining to either randomised controlled trials (RCT) aiming to reduce inappropriate prescribing or qualitative/mixed method studies of stakeholder views, were included. Results: Of 273 records identified, 11 systematic reviews were included. The quality of reviews ranged from critically low to moderate. There was mixed evidence for the use of education-only interventions. Multicomponent interventions (typically staff education combined with organisational and structural components), medication review, and interventions aimed at cultural change were evidenced as effective compared to care as usual. Stakeholders cited the importance of multidisciplinary collaboration and targeting organisational climate in changing psychotropic prescribing behaviours. Conclusions: The inappropriate use of psychotropic medications in nursing homes for PwD is a complex issue with many contextual factors. The evidence suggests a comprehensive approach, targeting organisational climate and multidisciplinary collaboration, along with staff education and training, may be an effective strategy.
