Preoperative PROMIS Scores Predict Postoperative Improvements Following Rotator Cuff Repair

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) has emerged as a valid and efficient means of collecting patient outcomes in patients with rotator cuff tear. The purpose of this study was to examine the role of pre-operative PROMIS computer adaptive test (CAT) scores in predicting post-operative PROMIS CAT scores as well as likelihood of achieving minimal clinically important difference (MCID) following rotator cuff repair. We hypothesize that pre-operative PROMIS CAT scores will directly impact both post-operative PROMIS CAT scores and likelihood of achieving MCID.Methods: Patients undergoing arthroscopic rotator cuff repair by one of three fellowship-trained surgeons were identified over a 12-month period. Only patients that completed pre-operative and 6-month post-operative PROMIS CAT assessments were included in this cohort. PROMIS CAT forms for upper extremity physical function (PROMIS-U), pain interference (PROMIS-PI), and depression (PROMIS-D) were utilized. MCID was calculated according to the distribution methodology, and receiver operating characteristics (ROC) were utilized to determine if pre-operative scores were predictive of post-operative outcomes. Preoperative cutoffs were used to predict which patients would likely meet MCID using 95% specificity. Results: A total of 80 patients met our inclusion criteria. PROMIS-UE, PROMIS-PI and PROMIS-D improved 6 months after surgery (p
