Est-il nécessaire d’évaluer à la fois les scores QuickDASH et PRWE?

Objective Hypothesis scoring systems are widely used in medicine and surgery. During the last decade, the reduced version of the disabilities of the arm, shoulder and hand score (QuickDASH) has established itself as the main patient reported outcome measures (PROMs) questionnaire used by hand surgeons. Another measurement tool can be used when the condition affects more precisely the wrist, the patient-rated wrist evaluation (PRWE). The aim of this study is to find out how correlated these two scores are. Materials and methods More than 2000 wrist clinical evaluations (including QuickDASH and PRWE) performed for any kind of condition the last two years, were gathered and analysed. Spearman's rank correlation coefficient was used to compare the visual analogic score for pain (VAS), QuickDASH and PRWE values. Results There is a high correlation between these three subjective scores. Spearman's rank correlation coefficient reaches 0.70 when assessing VAS and QuickDASH, 0.73 when assessing VAS and PRWE, and 0.86 when assessing PRWE and QuickDASH. Conclusions With the statistical power that provides a huge sample, it is proven that QuickDASH and PRWE scores are highly correlated. Thus, we can abandon one of them to spare time without losing relevant information.
