title: Peritonitis and exit site infections in First Nations patients on peritoneal dialysis.
abstract: OBJECTIVE
  First Nations (FN) patients on peritoneal dialysis experience poor outcomes. Whether discrepancies exist regarding the microbiology, rate of infections, and outcomes between FN and non-FN peoples remains unknown. Design, setting, participants, & measures: All adult peritoneal dialysis patients (n = 727) from 1997 to 2007 residing in Manitoba, Canada, were included. Parametric and nonparametric tests were used as necessary. Negative binomial regression was used to determine the relationship of rates of exit site infections (ESIs) and peritonitis between FN and non-FN peoples.
  
  
  RESULTS
  A total of 161 FN and 566 non-FN subjects were included in the analyses. The unadjusted relative rates of peritonitis and ESIs in FN subjects were 132.7 and 86.0/100 patient-years compared with 87.8 and 78.2/100 patient-years in non-FN populations, respectively. FN subjects were more likely to have culture-negative peritonitis (36.5 versus 20.8%, P < 0.0001) and Staphylococcus ESIs (54.1 versus 32.9%, P < 0.0001). The crude and adjusted rates of peritonitis were higher in FN subjects for total episodes and culture-negative and gram-negative peritonitis. Catheter removal because of peritonitis was similar in both groups (42.9 versus 38.1% for FN and non-FN subjects, respectively; P = 0.261).
  
  
  CONCLUSIONS
  FN patients experience higher rates of peritonitis and similar rates of ESIs compared with non-FN patients. Interventions to improve outcomes and prevent infections should specifically be targeted to the FN population.
