Systematic review: Effective home support in dementia care, components and impacts - Stage 2, effectiveness of home support interventions.

Aim: The aim of this study was to explicate the outcomes of home support interventions for older people with dementia and/or their carers to inform clinical practice, policy and research.

Background: Most people with dementia receive support at home. However, components and effectiveness of home support interventions have been little explored.

Design: Systematic review with narrative summary.

Data Sources: Electronic searches of published studies in English using PubMed, Cochrane Central Register of Controlled Trials, PsychINFO, CINAHL, Applied Social Science Index and CSA Social Services Abstracts. Databases and sources were searched from inception to April 2014 with no date restrictions to locate studies.

Review Methods: The PRISMA statement was followed and established systematic review methods used. Using 14 components of care for people with dementia and their carers, identified previously, data across studies were synthesized. Interventions were grouped and described and effectiveness ratings applied. Qualitative studies were synthesized using key themes.

Results: Seventy studies (four qualitative) were included. Most were directed to carers and of high quality. Seven interventions for carers and two for people with dementia were identified, covering 81% of studies. Those relating to daily living, cognitive training and physical activity for people with dementia were absent. Measures of effectiveness were influenced mainly by the intensity (duration and frequency) of interventions. Those containing education, social support and behaviour management appeared most effective.

Conclusion: These interventions reflect emergent patterns of home support. Research is required to identify effective interventions linked to the stage of dementia, which can be applied as part of routine clinical care.
