Abstract

Treatment success in Dupuytren´s disease has traditionally been assessed by clinical examination and physical measures, but based on patient orientation, patient-reported outcome measures (PROMs) can be used to quantify treatment impacts and health-related quality of life. The aim of this study was to compare the most widely used PROMS in Dupuytren´s disease, their psychometric properties, and their association with objectively measured hand function. We show a prospective study in which two disease-specific questionnaires (URAM scale and SDSS) and two hand-specific questionnaires (briefMHQ and PEM) were administered before and a month after the treatment with collagenase. Psychometric properties (construct validity, internal consistency, test-retest reliability, internal and external responsiveness, reliability, and minimal clinically important difference (MCID)) were calculated for all the questionnaires. Ninety-two completed both sets of questionnaires. Pre- and post-treatment scores were strongly correlated (Spearman rho >0.6) for all questionnaires. High internal consistency (Cronbach alpha >0.88) was observed for all the questionnaires. Test-retest reliability was also significant, with an ICC of >0.50 in all cases. The MCID was similar for three of the questionnaires (URAM, 11.528/45=0.256; SDSS, 5.079/20=0.254; and PEM, 21.542/77=0.215) and somewhat lower for the briefMHQ (10.617/60=0.177). No correlations were observed between treatment outcome and treated hand (r = 0.107; p = 0.31), joint (r = 0.163; p = 0.12), or finger (r = -0.151; p = 0.15). In conclusion, we did not find that any one questionnaire performed better than the other in detecting perceived changes in health status among patients with Dupuytren´s disease treated with collagenase.
