Predictors of patient satisfaction after reverse shoulder arthroplasty

© 2019 Journal of Shoulder and Elbow Surgery Board of Trustees Hypothesis: The aims of this study were to determine patient satisfaction and to identify predictors of satisfaction after reverse shoulder arthroplasty (RSA). We hypothesized that the majority of patients would be satisfied after RSA and that patients with worse preoperative mental and physical health would be less satisfied. Methods: Satisfaction was assessed 2 years after primary RSA with domains for pain, work, activities, quality of life, and overall satisfaction. Preoperative and postoperative patient-reported factors were measured using the American Shoulder and Elbow Surgeons (ASES) shoulder score, Shoulder Activity Scale score, Short Form 12 (SF-12) mental and physical component summary scores, and visual analog scale (VAS) pain, fatigue, and general health scores. Pearson correlations were used to determine the relationship between patient-reported factors and satisfaction. Multivariate regression was performed to control for potential confounding variables. Results: A total of 161 patients were evaluated at 2 years postoperatively. Patients were “very satisfied” in an average of 3.3 of the 5 domains. Improvements in ASES, Shoulder Activity Scale, VAS pain, and SF-12 physical component summary scores were associated with higher satisfaction, with correlation coefficients ranging from 0.27 to 0.49. On multivariate analysis, patients with higher preoperative ASES scores were less satisfied after surgery (P = .005). In addition, patients with worse VAS fatigue (P = .011) and SF-12 mental (P = .034) and physical (0.011) component summary scores preoperatively had lower satisfaction. Conclusion: Improvements in pain and outcome scores are associated with increased satisfaction. Patients with higher shoulder function, worse physical health, and worse mental health prior to surgery are more likely to have lower satisfaction after RSA.
