According to results, a significantly higher risk of infection was seen in patients on hemodialysis compared with patients on peritoneal dialysis after total hip or total knee arthroplasty.
Using Medicare files, researchers identified 531 patients who underwent TKA and 572 patients who underwent THA and were on peritoneal dialysis. Patients were matched 1:1 to patients on hemodialysis and 1:3 with patients who were not on either form of dialysis. Adverse events, which included prevalence of infection at 1 year and hospital readmission at 30 days, were determined with multivariate regression analysis.
Results showed the infection rate at 1 year after THA was 1.5% in patients on peritoneal dialysis and was 4.2% in those on hemodialysis, with an odds ratio of 0.3. At 1 year, the infection rate for patients who underwent TKA was 3.39% for those on peritoneal dialysis and was 6.03% for those on hemodialysis. Investigators noted patients on peritoneal dialysis had a similar infection rate compared with matched control patients. The rates of hospital readmission, emergency room visits, and mortality were similar in patients on peritoneal dialysis vs. hemodialysis; however, these rates were significantly higher than those of patients not on dialysis. – by Monica Jaramillo
