Abstract

BACKGROUND:

The Patient-Reported Outcomes Measurement Information System (PROMIS) has recently been validated in orthopedic patients with upper-extremity disease. The purpose of this study was to describe preoperative and postoperative PROMIS scores in total shoulder arthroplasty (TSA) patients, compare PROMIS physical function (PF) scores with clinical functional measurements, and determine whether preoperative PROMIS scores could predict achievement of the minimal clinically important difference (MCID) postoperatively.

METHODS:

Preoperative and postoperative (>3 months) PROMIS scores in patients who underwent primary anatomic TSA were reviewed. Preoperative and postoperative shoulder forward flexion and external rotation were also collected. PROMIS PF, pain interference (PI), and depression scores were compared. Accuracy analyses determined whether preoperative PROMIS scores from each domain could predict postoperative achievement of the MCID in the same domain.

RESULTS:

The study included 62 patients. Significant improvements in PROMIS PF, PI, and depression scores, as well as forward flexion and external rotation, were found postoperatively (P < .001). The multivariate model demonstrated that preoperative PROMIS PF, PI, and depression scores were predictive of postoperative achievement of the MCID (area under the receiver operating characteristic curve, 0.70-0.87). Ninety percent cutoff scores showed that patients with a preoperative PF score lower than 31.7, PI score greater than 66.9, and depression score greater than 55.5 were more likely to achieve the MCID.

CONCLUSIONS:

In TSA patients, preoperative PROMIS PF, depression, and PI scores demonstrated strong to excellent abilities to predict postoperative achievement of the MCID. PROMIS PF scores were responsive to the functional improvements observed clinically. The reported cutoff scores allow surgeons to identify patients with increased or decreased probabilities of achieving a clinically meaningful improvement after TSA.
