This validation study establishes clinical significance thresholds for the PROMIS Upper Extremity v2.0 score in total shoulder arthroplasty patients. It calculates the MCID, SCB, and PASS using both anchor-based and distribution-based methods. The goal is to let clinicians interpret whether a change in PROMIS UE score is truly meaningful to patients.
When you read a shoulder arthroplasty paper reporting a mean PROMIS UE improvement, this study tells you how to judge it. A change below 8.05 points is unlikely to matter to the patient, even if the p-value is impressive. A change of 10 or more reflects the kind of result patients call "much better."
PASS works differently: it is an absolute postoperative score. A patient scoring 37.2 or higher is likely satisfied, which is useful for setting expectations and defining responders. The key teaching point is that these values are procedure-specific. The TSA MCID of 8.05 is nearly double the rotator cuff repair value of 4.87, so you cannot apply one procedure's threshold to another.
Also remember these are population benchmarks, not universal rules. The authors caution that clinically meaningful change should still be judged patient by patient.
