AbstractBackgroundThere is often a `care gap` where people are given a clinical diagnosis of dementia but receive no useful support. (Foley, T. et al., 2019) However, the early stages of dementia are a crucial time for supportive interventions such as advice and strategies to cope with impairments and improve wellbeing and signposting through complex healthcare systems to access key supports and services. In February 2018 the National Dementia Office (NDO) commissioned the Dementia Services Information and Development Centre (DSIDC) to develop a guidance document to support health and social care professionals (HSCPs) establish, organise and facilitate evidence-based post-diagnostic pyschoeducatonal interventions in the community.MethodsThe DSIDC undertook an extensive literature review examining the evidence for multi-component psychoeducational interventions. An experienced group of health and social care professionals provided additional material and expertise resulting in the development of the final guidance document. Members of the Irish Working Group of People with Dementia and the Dementia Carers Campaign Network also reviewed the document.ResultsThe literature review found a growing evidence base for dyadic interventions. These interventions, directed at the person with dementia and their care partner, were diverse in their content, outcomes, the measures they used, their frequency and the professional background of the facilitators. They were flexible and cost-effective and drew on the HSCP`s own professional knowledge, service resources and experiences of what works and what doesn`t.ConclusionDyadic interventions (and psychoeducational programmes in particular) have the potential to benefit both people with dementia and their care partners by decreasing depression and anxiety, increasing knowledge and coping skills and helping improve cognitive function. (Moon and Betts Adams, 2012) The practical guidance document developed from this review provides HSCPs with useful advice and information to facilitate the setting up and running of post-diagnostic psychoeducational support programmes.
