C10D Utility Value Assessment in a Follow-Up Study of Patients

A follow-up study was conducted to assess the utility value of the C10D questionnaire. Healthcare professionals contacted 47 patients by phone after 7 days to collect data for retesting analysis. Three months later, data was collected from 177 patients to measure responsiveness. The utility values of C10D were measured three times, resulting in values of 0.68±0.20, 0.74±0.18, and 0.82±0.19. A 5L questionnaire was administered at baseline as a scale, producing a utility value of 0.75±0.22 (Fig. 1).
