Outcomes Following Revision Joint Arthroplasty Among Hemodialysis-Dependent Patients.

Abstract

BACKGROUND:

Hemodialysis (HD) dependence is known to impact the integrity of bone and has long been associated with metabolic bone disease and other adverse events postoperatively. The aim of this study is to analyze postoperative outcomes following revision hip and knee arthroplasty in hemodialysis-dependent (HDD) patients and to characterize the common indications for revision procedures among this patient population.

METHODS:

A total of 1779 HDD patients who underwent a revision joint arthroplasty (930 revision total knee arthroplasty [TKA] and 849 revision total hip arthroplasty [THA]) between 2005 and 2014 were identified from a retrospective database review. Our resulting study groups of revision TKA and THA HDD patients were compared to their respective matched control groups for hospital length of stay (LOS), 90-day mean total cost, hospital readmission, and other major medical and surgical complications.

RESULTS:

HD was significantly associated with increased LOS (7.7 ± 8.3 vs 4.8 ± 4.5; P < .001), mean 90-day total cost ($47,478 ± $33,413 vs $24,286 ± $21,472; P < .001), hospital readmission (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.96-2.58; P < .001), septicemia (OR, 3.18; 95% CI, 2.70-3.74; P < .001), postoperative infection (OR, 1.72; 95% CI, 1.50-1.98; P < .001), and mortality (OR, 3.99; 95% CI, 3.12-5.06; P < .001) following revision TKA. Among revision THA patients, HD was associated with increased LOS (9.4 ± 9.5 vs 5.7 ± 5.7; P < .001), mean 90-day total cost ($40,182 ± $27,082 vs $26,519 ± $22,856; P < .001), hospital readmission (OR, 2.33; 95% CI, 2.02-2.68; P < .001), septicemia (OR, 3.61; 95% CI, 3.05-4.27; P < .001), and mortality (OR, 3.55; 95% CI, 2.86-4.37; P < .001).

CONCLUSION:

HD remains a significant risk factor for increased LOS, mean total cost, hospital readmission, septicemia, and mortality following revision joint arthroplasty.
