Abstract

BACKGROUND:

The Patient-Reported Outcomes Measurement Information System (PROMIS) is being used to assess outcomes in many patient populations despite limited validation. The purpose of this study was to investigate the relationship between American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) scores and PROMIS Physical Function (PF) and Upper Extremity (UE) function scores collected preoperatively in patients undergoing rotator cuff repair.

METHODS:

This cross-sectional study analyzed 164 consecutive patients undergoing arthroscopic rotator cuff repair. Study inclusion required preoperative completion of the ASES and SST evaluations, as well as the PROMIS PF, UE, and Pain Interference computerized adaptive tests. Descriptive statistics were produced, and Pearson correlation coefficients were calculated between each of the outcome measures.

RESULTS:

Average PROMIS UE scores indicated greater impairment than PROMIS PF scores (34 vs 44). Three percent of patients reached the PROMIS UE ceiling score of 56. PROMIS PF scores demonstrated a weak correlation with ASES scores (r = 0.43, P < .001) and a moderate correlation with SST scores (r = 0.51, P < .001). PROMIS UE scores demonstrated a moderate correlation with both ASES scores (r = 0.59, P < .001) and SST scores (r = 0.62, P < .001). PROMIS Pain Interference scores demonstrated weak negative correlations with both ASES scores (r = -0.43, P < .001) and SST scores (r = -0.41, P < .001). Patients answered fewer questions on average using the PROMIS PF and UE instruments as compared with the ASES and SST instruments.

CONCLUSION:

PROMIS UE scores indicate greater impairment and demonstrate a stronger correlation with the legacy shoulder scores than PROMIS PF scores in patients with symptomatic rotator cuff tears. PROMIS computerized adaptive tests allow for more efficient patient-reported outcome data collection compared with traditional outcome scores.
