Abstract
OBJECTIVE: To derive the health utility scores of type 2 diabetes (T2D) patients using basal insulin (BI) with diverse characteristics in China. METHODS: The study used the data of insulin-using T2D patients on BI treatment enrolled in the BEYOND II study, which is a multi-center, observational study from 78 hospitals nationwide. The 3-level EQ-5D (EQ-5D-3L) questionnaire was administered to each patient to derive their health utility scores using the EQ-5D-3L value set for China. Patients' clinical and sociodemographic information were retrieved from their electronic case report form (eCRF). Ordinary least-square models with different specifications were explored to identify the best-fitting model to predict the utility scores. RESULTS: The sample (n = 12,583) achieved a mean (standard deviation) EQ-5D-3L utility score of 0.936 (0.120). According to the model, a Chinese male who was younger than 59 years, not underweight, diagnosed with T2D shorter than 10 years, with controlled plasma glucose and free of diabetes complications/comorbidities, would have a mean utility of 0.993. Being female, older age, underweight, and higher plasma glucose, longer diabetes duration was negatively related to EQ-5D-3L scores. Comorbidities and seven of eleven complications were associated with utility decrement. Interactions between some complications were also discovered. CONCLUSIONS: The derived health utility scores for diabetes complications could facilitate the assessment of the cost-effectiveness of health interventions for Chinese insulin-using T2D patients.
