[Incidence, prevalence and risk factors for a first infectious complication on a totally implantable venous-access port]. / Incidence, prévalence et facteurs de risque de survenue d'une première complication infectieuse sur chambres à cathéter implantables.

ABSTRACT

BACKGROUND: Totally implantable venous-access ports (TIVAP) should present less risk of complications than central venous catheters over a long time period. AIMS: Firstly, the study's objective was to assess the prevalence and incidence of a first infectious complication on a TIVAP and secondly, to assess the risk factors associated with this first infection. METHODS: The authors made a longitudinal historical cohort study of patients with a TIVAP in 2003, in the Dijon University Hospital. RESULTS: Two hundred and nineteen patients (sex-ratio 1.9) were included, with a total follow-up of 92,773 patients-days. Ninety percent of the TIVAP were used for chemotherapy, 5% for antibiotic drug administration, 2% for parenteral nutrition and 3% for other reasons (recurrent blood transfusions, etc.). Overall, 34 (16.3%) out of 209patients presented with at least one infectious complication, with an incidence rate of 0.37infection/1,000patients-days. The 5-year cumulative probability to be free of infectious complication was only 62.8%. In multivariate analysis, only underlying hematological neoplasia (by contrast with solid tumors) was significantly associated to a higher risk of infectious complication. CONCLUSIONS: The infectious risk linked to the use of TIVAP is significant, higher in case of underlying hematological neoplasia and during the first months of use.
