Association Between Quality of Life of Demented Patients and Professional Knowledge of Care Workers

Abstract

Professional knowledge about dementia and care methods is necessary for the appropriate care of demented people. In this study, the quality of life of 91 demented people staying at 12 care institutions was evaluated with the Quality of Life Questionnaire for Dementia (QOL-D). The amount of professional knowledge was evaluated in 140 staff members who took care of the patients using the professional knowledge test (PKT), and the mean PKT score was calculated for each institution (professional knowledge of institution). A positive significant correlation was observed between the QOL-D score and the professional knowledge of institution. The correlation remained significant when age, sex, and severity of dementia of demented patients were partialled out. This result indicated that the quality of life of demented people was better at institutions with staff members having more professional knowledge, indicating the importance of education of staff members and the possibility that such education improves the quality of life of the demented people.
