Summary
This study developed specific utility weights for the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 10 Dimensions (QLU-C10D) in Norway and Sweden. These weights will improve cancer care cost-utility analyses in these regions.
Area of Science:
- Health Economics
- Psychometrics
- Oncology
Background:
- Cancer care decision-making requires accurate health utility measures.
- Existing utility instruments may not reflect specific population preferences.
- The European Organization for Research and Treatment of Cancer (EORTC) QLU-C10D is a cancer-specific utility instrument.
Purpose of the Study:
- To develop population-specific utility weights for the EORTC QLU-C10D in Norway and Sweden.
- To support precise healthcare decision-making in cancer treatment and care within these national contexts.
Main Methods:
- A cross-sectional study involving 1019 Norwegian and 1048 Swedish participants.
- Discrete choice experiment with 960 choice sets evaluating EORTC QLU-C10D health states.
- Utility weights calculated using generalized estimation equation models.
Main Results:
- Physical functioning, pain, and role functioning showed the largest utility decrements in both populations.
- Specific decrements were observed for nausea and emotional functioning in Sweden.
- Norwegian participants showed larger decrements in physical functioning and pain compared to Swedes.
Conclusions:
- This study presents the first EORTC QLU-C10D utility weights tailored for Norwegian and Swedish populations.
- These weights reflect unique population health preferences, enhancing cost-utility analyses.
- Optimized resource allocation in cancer care is facilitated for the Norwegian and Swedish healthcare systems.
