Health utility is a quantitative global measure of patients’ health status. This retrospective cohort study aimed to compare health utilities of patients with mild to moderate versus severe carpal tunnel syndrome and determine inter-instrumental agreement. Health utilities of 29 patients with varying severity of carpal tunnel syndrome were measured indirectly by Short-Form Sixth Dimension and EuroQol 5D questionnaire and directly by Chained Standard Gamble and a visual analogue scale. Health utility was 0.69 for Short-Form Sixth Dimension, 0.78 for EuroQol 5D Questionnaire, 0.98 for Chained Standard Gamble, and 0.76 for the visual analogue scale. There was a significant inter-instrumental agreement between three of the instruments, but not the Chained Standard Gamble. The difference in health utilities between patients with mild or moderate versus severe carpal tunnel syndrome was significant only for the EuroQol 5D questionnaire. We conclude based on our results that there are no clear indications on how health utilities can be integrated into decision analysis models and economic evaluation regarding carpal tunnel syndrome of various severities . Level of evidence: IV

Health preferences have not previously been investigated among patients with tuberculous infection or disease. The authors assessed the reliability of visual analogue scale (VAS) and standard gamble (SG) measurements in this patient population. Participants were interviewed 3 times in English or French, at weekly intervals. They evaluated their own health status, as well as 3 marker health states, derived by consensus among tuberculosis (TB) practitioners. For the VAS, health states were assigned a duration of 6 months, whereas for the SG, the duration was 10 years. One hundred eighty-six potentially eligible individuals were identified from the TB clinic database of the Montreal Chest Institute. One hundred twelve (60%) were successfully located; of these, 106 were confirmed eligible. Sixty-seven (63%) agreed to participate, and 50 completed all study measurements (25 treated for latent TB, 17 treated for active TB, and 8 with previous active TB); 38 out of 50 were foreign-born. Intraclass correlation coefficients for the marker states were 0.57 to 0.81 for the VAS, and 0.75 to 0.87 for the SG. For respondents’ own health, the coefficients were 0.60 and 0.87, respectively. Median VAS scores for respondents’ own health were 85.0 to 88.0 for the 3 interviews, whereas the median utility score was 97.5 for all 3. Administration of the visual analogue scale and standard gamble instruments appeared reliable in a selected group of tuberculosis patients. Major barriers to recruitment were language and mobility in this largely foreign-born population.
