Aims

The aim of this study was to investigate the differences in 30-day outcomes between patients undergoing revision for an infected total hip arthroplasty (THA) compared with an aseptic revision THA.

Patients and Methods

This was a retrospective review of prospectively collected data from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database, between 2012 and 2017, using Current Procedural Terminology (CPT) codes for patients undergoing a revision THA (27134, 27137, 27138). International Classification of Diseases Ninth Revision/Tenth Revision (ICD-9-CM, ICD-10-CM) diagnosis codes for infection of an implant or device were used to identify patients undergoing an infected revision THA. CPT-27132 coupled with ICD-9-CM/ICD-10-CM codes for infection were used to identify patients undergoing a two-stage revision. A total of 13 556 patients were included; 1606 (11.8%) underwent a revision THA due to infection and there were 11 951 (88.2%) aseptic revisions.

Aims

The aim of this study was to compare the rate of perioperative complications following aseptic revision total hip arthroplasty (THA) in patients aged ≥ 80 years with that in those aged < 80 years, and to identify risk factors for the incidence of serious adverse events in those aged ≥ 80 years using a large validated national database.

Patients and Methods

Patients who underwent aseptic revision THA were identified in the 2005 to 2015 National Surgical Quality Improvement Program (NSQIP) database and stratified into two age groups: those aged < 80 years and those aged ≥ 80 years. Preoperative and procedural characteristics were compared. Multivariate regression analysis was used to compare the risk of postoperative complications and readmission. Risk factors for the development of a serious adverse event in those aged ≥ 80 years were characterized.

Introduction. The Comprehensive Care for Joint Replacement (CJR) initiative was implemented to address the two most commonly billed inpatient surgical procedures, total hip and knee arthroplasty. The primary purpose of this manuscript is to review the economic implications of one institution's mandatory involvement in CJR in comparison to prior involvement in Bundled Payment for Care Improvement (BPCI). Methods. The average cost per episode of care (EOC) was calculated using our institution's historical data. The target prices, projected savings or losses per EOC, and the projected annual savings for both BPCI and CJR were established and comparatively analyzed. Results. The CJR target prices will decrease in comparison to BPCI target prices by: 24% for MS-DRG 469 without fracture, 22.8% for 469 with fracture, 26.1% for 470 without fracture, 27.7% for 470 with fracture; resulting in a reduction in savings per EOC by: 92.8% for MS-DRG 469 without fracture, 166.0% for 469 with fracture, 94.9% for 470 without fracture, 61.7% for 470 with fracture (Table 1). This institution's projected annual savings under CJR will decrease by 83.3%. Conclusion. These results suggest that the margin for savings in CJR will be substantially reduced compared to those in BPCI. Hospitals resources previously devoted will have far less impact in CJR and hospitals new to CJR who have not made these investments previously, will require even greater resources for developing cost-reduction and quality control strategies to remain financially solvent.
