BackgroundHealth-related quality-of-life (HRQoL) scores are required for cost-effectiveness and health-care value analysis. We evaluated HRQoL scores and patient-reported outcome measures (PROMs) in patients with advanced glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty to establish values of HRQoL scores that can be used for cost-effectiveness and value analysis and to assess relationships between HRQoL scores and shoulder and upper-extremity PROMs.MethodsWe analyzed 143 patients (143 shoulders) with glenohumeral osteoarthritis treated with anatomic total shoulder arthroplasty; 92 patients had 1-year follow-up. Preoperative and postoperative functional outcomes were assessed with the Disabilities of the Arm, Shoulder and Hand (DASH) score, the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST), and a visual analog scale (VAS) for shoulder pain and function. Health utility was assessed with the EuroQol-5 Dimensions (EQ-5D), Short Form-6 Dimensions (SF-6D), and VAS Quality of Life (VAS QoL). HRQoL score validity was determined through correlations between the PROMs and HRQoL scores. The responsiveness of HRQoL scores was measured through the effect size and the standardized response mean.ResultsThere were significant improvements in all PROMs and HRQoL scores (p < 0.001) at 1 year after the surgical procedure. The changes in VAS QoL (very weak to moderate), EQ-5D (weak), and SF-6D (weak) were significantly correlated (p < 0.05) with the changes in PROMs, demonstrating comparably acceptable validity. There were large effect sizes in the VAS QoL (1.843), EQ-5D (1.186), and SF-6D (1.084) and large standardized response mean values in the VAS QoL (1.622), EQ-5D (1.230), and SF-6D (1.083), demonstrating responsiveness. The effect sizes of all PROMs were larger than those of the HRQoL scores.ConclusionsPROMs and HRQoL scores are not interchangeable, and studies of the cost-effectiveness and value of shoulder arthroplasty should incorporate both shoulder and upper-extremity PROMs and HRQoL scores. The findings of this study provide data on HRQoL scores that are specific to the treatment of advanced glenohumeral osteoarthritis with anatomic total shoulder arthroplasty and can be used for future cost-effectiveness and value analysis studies.Level Of EvidenceTherapeutic Level IV.
