C10D Utility Value Assessment in a Longitudinal Study

A longitudinal study was conducted to assess the utility value of the C10D instrument. Healthcare workers conducted a follow-up phone survey after 7 days, collecting data from 47 patients for retesting analysis. Three months later, data was collected from 177 patients to estimate reaction time. The C10D utility values were measured at three time points, resulting in the following values: 0.68±0.20, 0.74±0.18, and 0.82±0.19. Additionally, a 5L questionnaire was administered at baseline, yielding a utility value of 0.75±0.22 (Fig. 1).
