[Infectious complications rate from hemodialysis catheters: experience from the French Polynesia]

The arterio-venous fistula (AVF) is the most common vascular access to perform hemodialysis (HD). The HD venous central catheter use should only be proposed to old patients and/or patients without vascular access construction feasibility. These HD catheters are often responsible of infectious and thrombosis complications. We performed, for the first time in French Polynesia, a retrospective study based on 214 patients receiving 618 HD catheters, to evaluate the infectious complication rate due to HD catheters. We showed that 17.4% of HD catheters present with infection. The number of bacteraemia due to HD catheters is 2.57/1000 days-catheters and the number of infection due to HD catheter is 1.43/1000 days-catheters. Eighteen percent of patients requiring an emergency HD without AVF access are transferred in intensive care unit due to infectious HD catheter complications. We observed a similar bacteriological environment than in literature. However, the number of tunneled HD catheter is really lower to that of the number required in European recommendations and we observed an abnormal number of non-functional AVF 1 month after creation. These results involve our nephrology unit to increase the number of tunneled catheters to limit the infectious risk and also to fit with the best practices guidelines.
