Background: Outcome scores are useful tools with respect to quantifying how pain and limitations in strength and movement affect the patient’s functionality and lifestyle. Three shoulder outcome methods [Oxford, Constant and QuickDASH (Disability of the Arm, Shoulder and Hand)] are commonly used in practice but collectively consist of 34 questions, taking approximately 7 min to complete. We have developed a concise shoulder assessment to derive three equivalent outcome scores in a 12-item patient-reporting questionnaire. Methods: Outcome scores from 1285 outpatients of an upper limb clinic were collected. The patient cohort consisted of 462 females and 823 males with a mean (SD) age of 47.2 (16.79) years (range 13 years to 90 years). Using a correlation matrix, a 12-item questionnaire was drafted. The combined shoulder assessment was validated by 227 patients; consisting of 101 females and 126 males with a mean (SD) age of 47.91 (16.63) years (range 13 years to 88 years). Results: Agreement was achieved between the two methods, with an equivalent Oxford Shoulder Score intraclass correlation (ICC) of 0.930, equivalent Constant Shoulder Score ICC of 0.942 and equivalent QuickDASH ICC of 0.869. Bland–Altman analyses showed no systematic differences. Large effect sizes highlighted the responsiveness to change. Conclusions: The new combined shoulder assessment is a more convenient and patient-friendly method to obtain equivalent Oxford, Constant and QuickDASH shoulder outcome scores.
