Valuing Chinese medicine quality of life-11 dimensions (CQ-11D) health states using a discrete choice experiment with survival duration (DCETTO)

Abstract

Objective To explore generating a health utility value set for the Chinese medicine Quality of life-11 Dimensions (CQ-11D), a utility instrument designed to assess patients’ health status while receiving TCM treatment, among the Chinese population. Methods The study was designed to recruit at least 2400 respondents across mainland China to complete one-to-one, face-to-face interviews. Respondents completed ten discrete choice experiment with survival duration (DCETTO) tasks during interviews. The conditional logit models were used to generate the health utility value set for the CQ-11D using the DCETTO data. Results A total of 2,586 respondents were invited to participate in the survey and 2498 valid interviews were completed (a completion rate of 96.60%). The modified conditional logit model with combing logically inconsistent levels was ultimately selected to construct the health utility value set for the CQ-11D instrument. The range of the measurable health utility value was -0.868 ~ 1. Conclusion The study provides the first utility value set for the CQ-11D among the Chinese population. The CQ-11D and corresponding utility value set can be used to measure the health utility values of patients undergoing traditional Chinese medicine interventions, and further facilitate relevant cost-utility analyses. The application of the CQ-11D can support TCM resource allocation in China.

Developing and testing culturally relevant bolt-on items for EQ-5D-5L in Chinese populations: a mixed-methods study protocol

“…Based on the evidence collected in the existing reviews and the above-mentioned qualitative study, we will conduct internal discussions to select potential candidate dimensions, which are widely mentioned or used in health description and measurement in China, for use in subsequent qualitative interviews with HRQoL experts and lay people. Because the TCM concepts reflect the understanding of health in the Chinese culture, 20 they will also be considered as potential bolt-on items.…”

“…However, these measures are not internationally recognised and, for example, CQ-11D is designed specifically for assessing disease impacts and health outcomes associated with traditional Chinese medicine (TCM) interventions. 20 Therefore, their usefulness in cross-country studies may be limited. The absence of value sets for most of these HRQoL measures also restricts their use, while both 3L and 5L have developed national value sets for use in China.…”
