The combined shoulder assessment: a convenient method for obtaining equivalent outcome scores:

BackgroundOutcome 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.MethodsOutcome 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).ResultsAgreement was achieved between t...
