Health economic evaluations of non-pharmacological interventions for persons with dementia and their informal caregivers: a systematic review

BACKGROUND: This systematic review aims to review the literature on trial-based economic evaluations of non-pharmacological interventions directly targeted at persons with dementia as well as persons with mild cognitive impairment and their respective caregivers. METHODS: A systematic literature research was conducted for the timeframe from 2010 to 2016 in the following databases: Centre for Reviews and Dissemination, EconLit, Embase, Cochrane Library, PsycINFO and PubMed. Study quality was assessed according to the Drummond criteria. RESULTS: In total sixteen publications were identified. Health economic evaluations indicated the cost-effectiveness of physical exercise interventions and occupational therapy. There was also evidence to suggest that psychological and behavioral therapies are cost-effective. Health economic studies investigating psychosocial interventions mainly targeted towards informal caregivers showed inconsistent results. CONCLUSIONS: Due to the increasing prevalence of dementia non-pharmacological interventions and their health economic impact are of increasing importance for health care decision-makers and HTA agencies.
