Hospital Network Centralization of Primary Total Joint Arthroplasty Is Associated With Reduced Early Complication Rates But Not Reduced Readmission or Reoperation Rates: A Retrospective Database Study

This retrospective database study found that increased centralization of primary TJA within a hospital network was associated with lower 90-day complication rates but not with 90-day readmission or 1-year revision rates. This suggests that structural changes within hospital networks may be beneficial to reduce early complications in this patient population. In addition, our findings suggest that risk adjustment in assessing non-modifiable patient and hospital risk factors may be important when assessing TJA outcomes.
