Abstract
There have been significant advancements in perioperative care for total knee arthroplasty (TKA). It is essential to quantify the impact of efforts to better optimize patients and deliver care. The purpose of this study is to assess trends in discharge destination, length of stay (LOS), and complications.
Patients undergoing primary TKA were identified in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and Humana claims databases using procedural codes. Patients were classified as being discharged home or not home (skilled nursing facility, acute rehab, other non-home destinations). Changes in discharge destination, LOS, comorbidity burden, readmissions, and reoperation were assessed.
In total, 254,195 ACS NSQIP patients underwent TKA, with an increase in home discharge from 67.2% in 2011 to 85.3% in 2017 (P < .0001). There were 178,071 TKA patients in the Humana database and home discharge increased from 62.1% in 2007 to 74.7% in 2016 (P < .0001). LOS decreased and proportion of patients with an American Society of Anesthesiologists score ≥3 or Charlson Comorbidity Index ≥2 increased significantly for both home and non-home going patients. Home going patients had a decrease in 30-day readmissions (ACS NSQIP: 2011: 3.6%, 2017: 2.7%, P = .001; Humana: 2007: 4.0%, 2016: 2.4%, P < .0001).
Patients undergoing TKA were discharged home more often, had shorter LOS, and had significantly lower readmission rates, despite an increasingly comorbid patient population. It is likely that these improvements in postoperative care have resulted in significant cost savings, for both payers and hospitals. The efforts necessary to create and maintain such improvements, as well as the source of data, should be considered when changes to reimbursement are being evaluated. The metrics studied in this paper should provide a comparison for further improvement with continued transition to bundle payments and transition to outpatient surgery with removal of TKA from the inpatient-only list.
