AIM: To study whether health utility scores can be derived from shoulder-specific scores.METHODS: Authors investigated two questions:(1) do the American Shoulder and Elbow Surgeons(ASES) score and the Constant score correlate with the EuroQo L(EQ-5D), a measure of health utility?(2) can the ASES and Constant scores be obtained from a complete study sample without bias? Thirty subjects with various shoulder diagnoses completed ASES, Constant, and EQ-5D instruments. Pearson correlations were calculated to assess the associations between EQ-5D score and ASES and Constant scores.RESULTS: The correlation between EQ-5D score and ASES score was 0.60(P < 0.001); it was 0.54 for EQ-5D and Constant scores(P < 0.003). A multiple regression model containing ASES score, Constant score, age, and gender failed to adequately predict EQ-5D. Moreover, 25% of patients meeting the inclusion criteria did not complete the ASES questionnaire because they did not feel that specific questions, such as “do usual sport-list” and “throw ball overhand,” applied to them.CONCLUSION: Authors’ results do not support the use of the ASES and Constant scores in predicting EuroQ ol health utility values. However, the Constant score was more suitable for this patient population because all patients were able to complete it.
