Introduction:As life expectancy increases, the incidence of shoulder arthroplasty continues to increase as well. There are few shoulder arthroplasty studies investigating perioperative complication, readmission, and mortality. Furthermore, with bundled payments on the horizon, the cost of shoulder arthroplasty has become a significant issue. Clarifying risk factors for the need for postdischarge acute care will be critical information due to the high cost of such care. The goal of this study was to compare discharge disposition, length of stay (LOS), perioperative complications, readmission, and mortality in elderly and nonelderly cohorts to determine whether age is a risk factor for shoulder arthroplasty.Materials and Methods:We retrospectively compared 89 elderly patients (80 years or older) and 86 nonelderly patients (79 years or younger) who underwent hemiarthroplasty, total shoulder arthroplasty, reverse total shoulder arthroplasty, or revision shoulder arthroplasty from 2007 to 2015. Baseline characteristics were compared between the 2 cohorts. We then compared discharge disposition, LOS, 90-day complication rate, readmission, and mortality between the 2 cohorts.Results:Average length of hospitalization and percentage of patients with greater than 2 days of hospitalization were significantly higher in the elderly cohorts. Forty-four percent of the elderly cohorts were discharged to a skilled nursing facility compared to 6% in the nonelderly cohorts (P < .0001). There were no significant differences found in 90-day major complication rate, readmission, or mortality.Discussion:Shoulder arthroplasty is a valuable surgery for various indications in the elderly population. However, the likelihood of a patient to need a prolonged hospitalization or skilled nursing facility care after surgery are important questions that need to be answered. Our study shows that age over 80 years is a risk factor for prolonged hospitalization and need for skilled nursing facility care after shoulder arthroplasty.Conclusion:We conclude that elderly patients who undergo shoulder arthroplasty are significantly more likely to have extended hospitalizations and to be discharged to skilled nursing facilities compared to nonelderly patients.
