Non-Pharmacological Interventions in the Management of Dementia-Related Psychosis: A Systematic Review and Meta-Analysis.

OBJECTIVE: As populations age globally, there is an increasing prevalence of dementia, with an estimated 153 million living with dementia by 2050. Up to 70% of people with dementia experience dementia-related psychosis (D-RP). Antipsychotic medications are associated with many adverse effects in older people. This review aims to evaluate the evidence of non-pharmacological interventions in managing D-RP. METHOD: The search of Medline, EMBASE, Web of Science, CINAHL, PsycINFO, and Cochrane included randomised controlled trials that evaluated non-pharmacological interventions. Data extraction and assessment of quality were assessed independently by two researchers. Heterogenous interventions were pooled using meta-analysis. RESULTS: A total of 18 articles (n = 2040 participants) were included and categorised into: sensory-, activity-, cognitive- and multi-component-orientated. Meta-analyses showed no significant impact in reducing hallucinations or delusions but person-centred care, cognitive rehabilitation, music therapy, and robot pets showed promise in single studies. CONCLUSIONS AND IMPLICATIONS: Future interventions should be developed and evaluated with a specific focus on D-RP as this was not the aim for many of the included articles.

Non-pharmacological interventions in the management of dementia-related psychosis.

BACKGROUND: It is estimated 20-70% of those living with a dementia diagnosis experience dementia-related psychosis (D-RP). D-RP results in decreased quality of life, increased carer burden, increased rapid cognitive decline, increased need for primary care support, and earlier care/nursing home admission, all which come at a considerable cost to the NHS. Antipsychotic medications prescribed by primary care services are typically used as treatment but have short-term efficacy and dangerous side effects. Effective management with the use of non-pharmacological interventions could safely improve the quality of life of those living with dementia, as well as reduce burden on primary care services and GPs. AIM: To evaluate the effectiveness of non-pharmacological interventions in the management of D-RP. Studies that measure the effect of non-pharmacological interventions on patient or caregiver quality of life or determine the cost-effectiveness and safety of non-pharmacological interventions against antipsychotic medications will also be included. METHOD: A global systematic literature review was conducted in Medline, Embase, PsychInfo, CINAHL, Web of Science, and CENTRAL. Included studies were analysed using meta-analysis and narrative synthesis. The protocol is registered with PROSPERO (ID: CRD42022294750). RESULTS: Data extraction of 18 included papers revealed 4 interventions to show evidence of efficacy in improving D-RP in older adults. Person-centred care, robot pets, cognitive rehabilitation, and music therapy significantly decreased psychosis in care homes and in participants living at home. These results are discussed, and implications noted. CONCLUSION: Future RCTs should focus on specifically improving D-RP, as this was not the primary aim for many interventions.

Clinical effectiveness of pharmacological and non-pharmacological treatments for the management of anxiety in community dwelling people living with dementia: A systematic review and meta-analysis.

People living with dementia commonly experience anxiety, which is often challenging to manage. We investigated the effectiveness of treatments for the management of anxiety in this population. We conducted a systematic review and meta-analysis of randomised controlled trials, and searched EMBASE, CINAHL, MEDLINE and PsycInfo. We estimated standardised mean differences at follow-up between treatments relative to control groups and pooled these across studies using random-effects models where feasible. Thirty-one studies were identified. Meta-analysis demonstrated non-pharmacological interventions were effective in reducing anxiety in people living with dementia, compared to care as usual or active controls. Specifically, music therapy (SMD-1.92(CI:-2.58,-1.25)), muscular approaches (SMD-0.65(CI:-1.02,-0.28)) and stimulating cognitive and physical activities (SMD-0.31(CI:-0.53,-0.09)). Pharmacological interventions with evidence of potential effectiveness included Ginkgo biloba, probiotics, olanzapine, loxapine and citalopram compared to placebo, olanzapine compared to bromazepam and buspirone and risperidone compared to haloperidol. Meta-analyses were not performed for pharmacological interventions due to studies' heterogeneity. This has practice implications when promoting the use of more non-pharmacological interventions to help reduce anxiety among people living with dementia.

Models of care and the role of clinical pharmacists in UK primary care for older adults: A scoping review protocol.

INTRODUCTION: There has been global investment of new ways of working to support workforce pressures, including investment in clinical pharmacists working in primary care by the NHS in the England. Clinical pharmacists are well suited to support older adults who have multiple long-term conditions and are on multiple medications. It is important to establish an evidence base for the role of clinical pharmacists in supporting older adults in primary care, to inform strategic and research priorities. The aim of this scoping review is to identify, map and describe existing research and policy/guidance on the role of clinical pharmacists in primary care supporting older adults, and the models of care they provide. METHODS AND ANALYSIS: A scoping review guided by the Joanne Briggs Institute methodology for scoping reviews, using a three-step strategy. We will search Medline, CINAHL, Scopus, EMBASE, Web of Science, PSYCHInfo, and Cochrane for English language articles, from 2015 -present day. Grey literature will be searched using Grey Matters guidelines, the Index of Grey Literature and Alternative Sources and Resources, and Google keyword searching. References of all included sources will be hand searched to identify further resources. Using the Population, Concept and Context framework for inclusion and exclusion criteria, articles will be independently screened by two reviewers. The inclusion and exclusion criteria will be refined after we become familiar with the search results, following the iterative nature of a scoping review. Data will be extracted using a data extraction tool using Microsoft Excel and presented using a narrative synthesis approach. ETHICS AND DISSEMINATION: Ethical approval is not required for this review. Review findings will be disseminated in academic conferences and used to inform subsequent qualitative research. Findings will be published and shared with relevant local and national organisations.
