Drivers of lower inpatient hospital costs and greater improvements in health-related quality of life for patients undergoing total shoulder and ream-and-run arthroplasty

Published:November 29, 2020DOI:https://doi.org/10.1016/j.jse.2020.10.030

      Background

      With increasing emphasis on value-based care and the heavy demands on the US health care budget, surgeons must be cognizant of factors that drive cost and quality of patient care. Our objective was to determine patient-level drivers of lower costs and improved health-related quality of life (HRQoL) in 2 anatomic shoulder arthroplasty procedures: total shoulder arthroplasty (TSA) and ream-and-run arthroplasty.

      Methods

      This study included 222 TSAs and 211 ream-and-run arthroplasties. Simple Shoulder Test, Single Assessment Numeric Evaluation, and Short Form 36 scores were collected preoperatively and 2 years postoperatively. Quality-adjusted life-years (QALYs) were calculated as a measure of HRQoL. Univariate and multivariate analyses determined factors significantly associated with decreased hospitalization costs and improved HRQoL.

      Results

      In the TSA group, female sex, lower American Society of Anesthesiologists class, diagnosis other than capsulorrhaphy arthropathy, lower pain score, and higher Single Assessment Numeric Evaluation score were associated with decreased total hospitalization costs; in addition, female sex was an independent predictor of lower total costs. Insurance other than workers' compensation, a diagnosis of chondrolysis, and higher optimism led to greater QALY gains, but a diagnosis of capsulorrhaphy arthropathy was the only independent predictor of greater QALY gains. In the ream-and-run arthroplasty group, older age, lower body mass index (BMI), lower American Society of Anesthesiologists class, insurance other than Medicaid, diagnosis other than capsulorrhaphy arthropathy, no history of surgery, higher preoperative Simple Shoulder Test score, and higher preoperative Short Form 36 Physical Component Summary score were associated with lower total costs; moreover, lower BMI was an independent predictor of lower costs. Higher preoperative optimism was an independent predictor of greater QALY gains.

      Conclusions

      Identifying factors associated with decreased costs and increased quality is becoming increasingly important in value-based care. This study identified fixed (sex and diagnosis) and modifiable (BMI) factors that drive decreased hospitalization costs and increased HRQoL improvements in shoulder arthroplasty patients. Higher preoperative patient optimism is a consistent predictor of improved HRQoL for both TSA patients and ream-and-run arthroplasty patients, and further study on optimizing the influence of patient expectations and optimism may be warranted.
