Predictive Value of the (Quick)DASH Tool for Upper Extremity Dysfunction Following Percutaneous Coronary Intervention

Area of Science:

• Cardiovascular Interventions
• Musculoskeletal Health
• Diagnostic Accuracy

Background:

• Transradial percutaneous coronary intervention (TR-PCI) is a common procedure.
• Assessing upper extremity function post-TR-PCI is crucial for patient recovery.
• Existing questionnaires like DASH and QuickDASH lack validation for TR-PCI complications.

Purpose of the Study:

• To validate the DASH and QuickDASH questionnaires for assessing upper extremity dysfunction after TR-PCI.
• To determine the diagnostic accuracy of these tools in identifying TR-PCI-related complications.

Main Methods:

• Retrospective analysis of the ARCUS study data.
• Included 440 patients who underwent TR-PCI and 62 controls (transfemoral approach).
• Utilized Receiver Operating Characteristic (ROC) curve analysis to assess questionnaire validity.

Main Results:

• Both DASH and QuickDASH showed poor discrimination ability (AUC: 0.565-0.586).
• No significant difference in performance between the two questionnaires.
• Questionnaires failed to reliably distinguish between patients with and without upper extremity dysfunction.

Conclusions:

• DASH and QuickDASH are not suitable for assessing upper extremity dysfunction specifically caused by TR-PCI complications.
• These tools are inadequate for discerning functional changes resulting from procedural issues versus other factors.
