Intervention service programmes for family caregivers of a relative with dementia: a systematic review

Abstract

Background: With the aging of the global population, the prevalence and incidence of Alzheimer’s disease or related dementia are increasing. Most mild or moderate dementia clients are taken care of at home by informal caregivers, which leave a heavy burden to the caregivers. Researchers have found out that with good intervention services and programmes for the caregivers, their burden, emotional distress and even the care recipients’ symptoms and institutionalization rates would be improved.

Objectives: This project is to review these researches to evaluate whether the interventions are effective and/ or cost-effective and how the decision-makers could use the results for evidence-based policy.

Methods: A literature search was performed on randomized controlled trials in education, information/ support intervention programmes published from October 2005 to July 2012. Electronic databases (EBSCO, PubMed and CNKI) were searched until July 2012. The Consolidated Standards of Reporting Trials (CONSORT) checklist for reporting randomized controlled trials was used as the guideline to evaluate the quality of identified papers.

Results: 16 papers (15 studies) were included in this review and classified into three groups, as home-based, individual-based and group-based interventions. This review found that the intervention programmes had various outcomes and showed some evidence of effectiveness. Most of the papers had good quality. The home-based programmes showed cost-effectiveness in the identified studies.

Conclusion: There was some evidence that the home- and group-based interventions were effective and the home-based interventions could be cost-effective. Further studies are recommended and a meta-analysis on the studies and more researches on economic analysis are needed. A community-based long-term dementia management should be built up for better outcomes.
