Research on the impact of diabetes on quality of life often focuses on understanding the effect of specific interventions. In a new publication, co-authors including Hasan Basarir, Director of Health Economics at RTI Health Solutions, present the valuation for a questionnaire that brings together the impact of diabetes on health and the associated self-management burden in a single descriptive system: Health and Self-Management in Diabetes (HASMID).
“In addition to focusing on the way diabetes impacts the day-to-day lives of people,” explains Dr. Basarir, “this study can potentially be used to compare different self-management interventions for diabetes using quality-adjusted life years (QALYs), which are based on the preference weights generated in the study, leading to a single utility value.” The results reported in the study can be used in relevant economic models to value the impact of the interventions on health and self-management. These could be combined with the impact of longer-term complications associated with diabetes on QALYs.
HASMID was developed to directly consider the impact of different self-management regimens on the quality of life of patients. The self-reported measure allows patients to reflect their own preferences on the regimens being evaluated and includes specific questions on both the health-related quality of life and the impact of self-management.
The authors argue that broadening the scope of QALYs beyond health could potentially have advantages in terms of comparability of assessments undertaken across different sectors (e.g., health and social care) and government agencies. However, it also raises issues of comparability with QALYs generated by other interventions, where the scope of the evaluation might have restricted the definition of QALYs to health alone.
