Impact Of Place Of Residence On Relationship Between Quality Of Life And Cognitive Decline In Dementia

The aim of this descriptive study was to estimate and compare the association between cognitive decline and quality of life (QOL) for 2 groups of dementia patients differing by place of residence: home or institution. Each subject was placed within a specific subgroup according to their Mini-Mental State Examination (MMSE) score and was evaluated by a QOL proxy-assessment [Alzheimer Disease Related Quality of Life (ADRQL)] and a dependency assessment (Katz Activities of Daily Living classification). For the "at home" and "institution" groups, global and subscale ADRQL scores showed significant differences between the 5 MMSE subgroups. Place of residence and MMSE subgroups significantly affected global and subscale ADRQL scores. The MMSE 4 to 8, 9 to 13, and 14 to 18 Subgroups had ADRQL global scores significantly better in the institution group than the at home group. In contrast, the MMSE 19 to 23 and 0 to 3 subgroups ha similar ADRQL global scores in both places of residence. In Conclusion, there is no direct relationship between cognitive decline and QOL, and QOL does not seem to be better at home compared with the institution.
