The authors assessed the diagnostic potential of commonly used patient-reported measures, namely, the Boston Carpal Tunnel Questionnaire (function and symptom severity), QuickDASH (a shortened version of the Disabilities of the Arm, Shoulder and Hand questionnaire), and the Short Form-8.


Measure scores were extracted retrospectively from the records of 262 patients (397 hands) and compared using analysis of variance to determine statistical differences among diagnoses assigned by the same surgeon at the time of visit. Patients were grouped into one of two diagnostic groups: those with Dupuytren disease and those with carpal tunnel, osteoarthritis, and tenosynovitis conditions. Logistic regression analysis was performed, and a receiver operating characteristic curve was used in data analysis.


Analysis of variance showed statistical differences among the five diagnoses for each patient-reported measure. Results showed that Dupuytren disease was significantly different from the other diagnoses. Carpal tunnel, osteoarthritis, and tenosynovitis conditions were statistically associated with higher Boston Carpal Tunnel Questionnaire function and symptom severity and QuickDASH scores compared with Dupuytren disease. Lower physical and mental summary Short Form-8 scores were associated with the carpal tunnel, osteoarthritis, and tenosynovitis conditions. QuickDASH scores of 25 or higher and Boston Carpal Tunnel Questionnaire symptom severity scores and function scores of 2.5 or higher and of 2 or higher, respectively, are the best patient-reported measure threshold values for distinguishing between the two diagnostic groups.


The QuickDASH and Boston Carpal Tunnel Questionnaire patient-reported measures have diagnostic potential. Establishing threshold values for predicting a diagnostic group may prove to be a useful tool for referring providers.
