Factors influencing quality of life of elderly people with dementia and care implications: a systematic review

Abstract

Background: Identifying factors associated with Quality of Life (QoL) of elderly people with dementia could contribute to finding pathways to improve QoL for elderly people in dementia.

Aim: This paper systematically reviews all possible factors that influence QoL of elderly people with dementia, identifies how these factors are different by different stages of dementia and living settings, and explores how the influencing factors could be perceive differently by elderly people with dementia, family members, and caregivers.

Method: PubMed, PsycINFO, Web of Science and DelphiS searches from 2000 to 2015 and hand searches of publication lists, reference lists and citations were used to identify primary studies on ‘quality of life’ and ‘dementia’ elderly people.

Results: The results suggest that there are a complex variety of factors influencing QoL of elderly people with dementia, and the factors cover demographic, physical, psychological, social, and religious aspects. And the factors influencing QoL of elderly people with dementia are different in different living settings (care institutions and communities) as well as different people’s perspectives (elderly people with dementia, family members and care staff). Environmental factors and quality of care are important for elderly people in care institutions; while religious seem to only affect QoL of those living in communities. However, this review fails to comprehensively identify unique or common factors associated QoL in dementia across three stages. Further study should pay more attention to comparing factors associated with QoL in dementia across three stages of dementia.
