Introduction: The QuickDASH is a valid and reliable outcome measure widely used to assess the function and pain in arm, shoulder, and hand disabilities. A recent study introduced a QuickDASH 80% cut point test to gauge patients at risk of poor outcomes. However, the utility of this test has not been validated.

Purpose: To determine typical QuickDASH scores for three upper limb conditions and to test the sensitivity and specificity of the QuickDASH 80% cut point test in predicting patients at risk of poor outcomes.

Methods: This is a retrospective study with a total of 406 patient records for whom QuickDASH scores were examined. The sensitivity and specificity of the QuickDASH 80% cut point test was investigated for three acute upper limb conditions seen in hand therapy: surgical distal radius fracture, nonsurgical lateral epicondylitis, and carpal tunnel release.

Results: Typical scores were determined for three upper limb conditions. The QuickDASH 80% cut point test per upper limb condition returned poor sensitivity between 28.57% and 41.67%.

Conclusion: The results did not support the QuickDASH 80% cut point test as a predictor of final outcome in these three patient populations. Patients with the worse initial 20% scores were not correctly classified as worse 20% final scores. This study provides summary data from three upper limb conditions to provide clinicians with comparison data to establish goals and educate patients.
