The development of quality indicators for Taiwanese institutional dementia care

Abstract

This study is a mixed-method study that seeks to develop a set of institutional dementia care indicators to evaluate quality of care and inform the improvement of quality of life (QOL) for Taiwanese people with dementia living in care homes. It also uses comparative analysis to compare the different features of policy and its delivery in dementia care between Scotland and Taiwan, a comparison designed to aid the development of dementia care policy, and the establishment of quality indicators for institutional dementia care, in Taiwan.

This study employed the person-centred care approach at the micro perspective, and the total quality management (TQM) approach at the macro perspective, in order to inform a seamless care model for people with dementia living in care homes. Data were collected in two stages: comments from experts in dementia care were recorded in an exercise using “Delphi” methodology; subsequently the opinions of service receivers were recorded in a fieldwork exercise. The Delphi exercise (stage one) acted as the pre-test, involving 24 experts in dementia care in Scotland and Taiwan in evaluating the usefulness and applicability of proposed quality indicators for institutional dementia care. Quantitative and qualitative data from the Delphi panel were analyzed. The fieldwork (stage two) collected 237 questionnaires (from 122 residents with dementia and 115 family members) in 14 Taiwanese care homes for people with dementia (including special care units within care homes). The field test data were analyzed using reliability and item analysis, confirmatory factor analysis (CFA), and descriptive and inferential statistics.

Initially, 43 proposed quality indicators for institutional dementia care were identified through literature review. However, after two Delphi rounds, only six key dimensions (41 quality indicators) were identified by consensus as the important items for use in measurement of quality of care for people with dementia living in Taiwanese care homes. Through reliability and item analysis, and CFA, this research developed a model which is a three-factor structure (social care, health and personal care, and environment) with 18 quality indicators. The 18 quality indicators have high reliability, validity, and credibility and load onto a second order factor which represents quality of care for people with dementia living in care homes. Further analysis was then conducted to explore how relative ratings on these three factors differed according to measured characteristics of the residents and their family members. In general, only a few strong patterns of difference emerged and multiple linear regression analysis suggested that differences in ratings could not be attributed to influences of socio-economic and socio-demographic differences between respondents.

The study concludes that the Delphi method could be used as a methodology for health services research to integrate the opinions of multidisciplinary dementia experts and that CFA is an effective technique to study the empirical factor structure. The findings suggest that the 18 quality indicators could be suitable criteria for people with dementia and their family members to evaluate care quality and select an appropriate care home. The indicators also have important policy implications for the Taiwanese Government and regulations intended to ensure that care homes meet the requirements of service receivers.
