Correlation of Patient Reported Outcome Measurement Information System (PROMIS) with American Shoulder and Elbow Surgeon (ASES), and Constant (CS) scores in Idiopathic Adhesive Capsulitis.

PURPOSE To correlate the Patient Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE) score with preexisting validated outcomes scores, American Shoulder and Elbow Surgeons score (ASES), and Constant score (CS) in patients with idiopathic adhesive capsulitis (AC). METHODS Patients with a clinical diagnosis of idiopathic AC ("freezing" or "frozen" phases) who agreed to complete the ASES, CS, and PROMIS UE scores during their office visit were included in this study. Trained researchers performed the objective clinical assessments on the included patients. Responses to the 3 outcomes scores were statistically analyzed and compared utilizing Pearson correlation coefficients. Floor and ceiling effects were calculated. RESULTS The final cohort included 100 patients with AC of which there were 72% female and 87% right hand dominant, with a mean age of 55 years. The PROMIS UE required fewer question responses (5.02 ±1.84) compared to the fixed questions burden with ASES (12) and CS (9). The mean outcome scores were 34.6 ± 2.5 (PROMIS UE), 55 ± 22 (ASES), and 51 ± 16 (CS). The PROMIS UE displayed excellent correlation with both the ASES (r = 0.80, 95% [CI: 0.72, 0.86], p < 0.001) and CS (r = 0.76, 95% CI [0.67, 0.83], p < 0.001). Neither ceiling nor floor effects were present. CONCLUSION The PROMIS UE displayed comparable efficacy to commonly used legacy outcome scores (ASES and CS) in adhesive capsulitis. A lower question burden with the PROMIS UE carries a potential for wider acceptibility with the researchers and patients with shoulder pathology.
