BackgroundIt 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.AimTo 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.MethodA 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).ResultsData 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.ConclusionFuture RCTs should focus on specifically improving D-RP, as this was not the primary aim for many interventions.© British Journal of General Practice 2024.
