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

Le résumé fourni par la source

Purpose: The use of the Disability of the Arm, Shoulder and Hand (DASH) questionnaire and its shortened version, the Quick DASH, have been used to assess upper extremity function following a transradial percutaneous coronary intervention (TR-PCI). However, the use of these scores has not yet been validated for TR-PCI induced complications in the upper extremity. The aim of this study was to establish the validity of the DASH and the Quick DASH, for the assessment of upper extremity dysfunction following a transradial percutaneous coronary intervention (TR-PCI). Patients and Methods: This study was a diagnostic retrospective analysis of the ARCUS study, of whom 440 underwent TR-PCI and 62 control patients were treated via the transfemoral approach. All participants completed the DASH and Quick DASH questionnaire prior to the procedure and at each follow-up visit up to six months of follow-up. Receiver operating characteristics (ROC) were constructed to determine the validity of the questionnaires, using physical examinations to determine the occurrence of upper extremity dysfunction, according to the ARCUS study. Results: At each follow-up moment, the area under the curve (AUC) showed a poor ability of the DASH and Quick DASH to discriminate between patients with and without upper extremity dysfunction (AUC: 0.565– 0.586). There was no significant difference between the questionnaires (p > 0.05). Conclusion: The DASH and Quick DASH questionnaires are both equally incapable of discriminating between patients with and without upper extremity dysfunction following a TR-PCI. Study results suggest that the DASH and Quick DASH questionnaires are incapable of discerning changes in upper extremity function as a result of procedural complications following a TR-PCI vs cardiac induced activity cessation.
