Abstract
The purpose of this study was to correlate the Patient-Reported Outcomes Measurement Information System (PROMIS) computer adaptive testing (CAT) domains with commonly used legacy patient-reported outcome measures (PROMs) preoperatively in a population of patients presenting to a tertiary care orthopedic center for biceps and labral pathology. Prospective data were collected on 175 patients scheduled to undergo isolated biceps tenodesis at a tertiary center. Enrollees completed legacy scores (Veterans RAND 12-Item Health Survey, Short Form 12, American Shoulder and Elbow Surgeons [ASES] Assessment Form, Single Assessment Numeric Evaluation, and Constant-Murley score) and PROMIS CAT questionnaires (Upper Extremity [UE], Pain Interference [PIF], and Depression). In addition, patients were asked to provide an assessment of the strength, function, and pain of the affected shoulder using a custom visual analog scale (VAS) questionnaire. Spearman rank correlations of the PROMIS CAT with legacy measures and the custom VAS were calculated. Floor and ceiling effects were assessed. The UE CAT yielded moderate correlations with the ASES score (r = 0.57) and the custom VAS strength score (r = 0.50-0.57). The PIF CAT demonstrated moderate correlations with the VAS pain score (r = 0.45) and high-moderate correlations with the ASES score, VR6D score, and UE CAT (r = 0.61-0.66). The Depression CAT demonstrated high-moderate correlations with the mental health legacy measures (r = -0.64 to -0.61). There was a significant relative floor effect for the Depression CAT at a score of 34.2 (19%). The PIF CAT was comparable to the ASES score, the current gold standard. Compared with legacy measures, both the UE CAT and PIF CAT are less burdensome and have few floor or ceiling effects. The PIF CAT may be a viable alternative to describe the physical and psychosocial impact of pain in biceps tenodesis patients.
