High-volume hospitals do not perform better than low-volume hospitals in septic and aseptic revision total hip arthroplasty: an analysis of re-revision risk and mortality based on the Dutch Arthroplasty Register.

ABSTRACT:

Background and purpose

 Revision total hip arthroplasty (rTHA) is a complex procedure that may benefit from centralization. We examined the association between annual hospital volume of rTHA and re-revision risk and mortality.

Methods

 We included all rTHAs between 2007 and 2022 in general hospitals, registered in the Dutch Arthroplasty Register (LROI; n = 12,515). Hospitals were categorized into low (< 25 rTHA/year) or high volume (≥ 25 rTHA/year). Competing-risk analyses and Cox proportional hazard regression analyses were performed to assess implant re-revision and Kaplan-Meier survival analysis for mortality. Results were stratified into septic (permanent Girdlestone, 1-stage, and 2-stage revisions) and aseptic first revisions.

Results
