Predictors of Postoperative Patient-Reported Outcome Measure Response Rates Among Patients With Rotator Cuff Repair.

ABSTRACT

BACKGROUND: Patient-reported outcome measures (PROMs) contribute to evaluating and improving the quality of patient care. Patient outcomes after rotator cuff repair (RCR) have been researched; however, the relationship between PROM response rates and individual and health care correlates has not been thoroughly investigated. PURPOSE: To examine differences in individual and health care factors among patients who had undergone RCR based on their PROM response rates. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Shoulder-specific and general PROMs were solicited via email and text message of all patients who underwent RCR between 2016 and 2020. Three subgroups were classified (1) complete responders completed all 1-year postoperative PROMs, (2) partial responders answered enough questions to produce ≥1 usable score, and (3) nonresponders did not respond to a single measure. Correlates were assessed using analysis of variance and chi-square tests. Adjusted multinomial logistic regression models identified predictors of 1-year PROM response. RESULTS: Of 2195 patients included at the 1-year follow-up, 34% were complete responders; 11%, partial responders; and 55%, nonresponders. Patients had a mean age of 61.8 years, 63% were men, and 90% were White. Pre- and postoperative PROM scores were similar across responder groups. In stepwise selection, 1-year responses (complete or partial) were associated with older age, later year of surgery, White race, and having workers' compensation insurance. The strongest predictor of PROM response was having workers' compensation insurance. CONCLUSION: Patients with workers' compensation insurance compared with other insurance types responded to PROMs at disproportionately higher rates. This could distort postoperative PROM scores in the population studied because there are known differences among patients with this insurance status.
