ABSTRACT: Purpose
Previous research suggests that treatment process can have an influence on patient preference and health state utilities. This study examined preferences and estimated utilities for treatment processes of two daily oral treatment regimens and two weekly injectable regimens for treatment of type 2 diabetes (T2D).Methods
Participants with T2D in the UK reported preferences and valued four health state vignettes in time trade-off utility interviews. The vignettes had identical descriptions of T2D but differed in treatment process: (1) daily simple oral treatment (tablets without administration requirements), (2) daily oral semaglutide (with administration requirements per product label), (3) weekly dulaglutide injection, (4) weekly semaglutide injection.Results
Interviews were completed by 201 participants (52.7% male; mean age = 58.7). Preferences between treatment processes varied widely. Mean utilities were 0.890 for simple oral, 0.880 for oral semaglutide, 0.878 for dulaglutide injection, and 0.859 for semaglutide injection (with higher scores indicating greater preference). All pairwise comparisons found statistically significant differences between utilities (p < 0.01), except the comparison between oral semaglutide and the dulaglutide injection (p = 0.49).Conclusions
Results suggest that routes of administration cannot be compared using only the simplest descriptions (e.g., oral versus injectable). Dose frequency and specific details of the treatment process administration had an impact on patient preference and health state utilities. The utilities estimated in this study may be useful in cost-utility models comparing these treatments for T2D. Results also suggest that it may be helpful to consider patient preferences for treatment process when selecting medications for patients in clinical settings.
