- Abstract
Background: We sought to develop mapping functions that use EORTC responses to approximate health utility (HU) scores for patients with head and neck cancer (HNC). Methods: In total, 209 outpatients with HNC completed the EORTC QLQ‐C30 & QLQ‐H&N35 (EORTC), EQ‐5D‐5L and the HUI‐3. Results of the EORTC were mapped onto both EQ‐5D‐5L and HUI‐3 scores using ordinary least squares regression and two‐part models. Results: The OLS model mapping EORTC onto the EQ‐5D‐5L performed best (adjusted R2 =.75, 10‐fold cross‐validation RMSE = 0.064, MAE 0.050). The HUI‐3 model mapping onto EORTC through OLS was more limited (adjusted R2 =.5746, 10‐fold cross cross‐validation RMSE = 0.168, MAE 0.080). The EQ‐5D‐5L model was able to discriminate between certain clinical indices of disease severity on subgroup analysis. Conclusion: The EORTC to EQ‐5D‐5L mapping algorithm has good predictive validity and may enable researchers to translate EORTC scores into HU scores for head and neck patients with cancer.
