Prevention of CR-BSI during long-term use of indwelling central venous catheters is important.
OBJECTIVE: To evaluate whether using a closed-hub system and waterproofing catheter hub connections reduces the rate of CR-BSI per 1,000 catheter-days.
DESIGN: Single-center open observational study (January 2003-December 2008).
PATIENTS: Pediatric patients with pulmonary arterial hypertension who received intravenous prostanoids.
METHODS: In July 2007, CR-BSI preventive measures were implemented, including the use of a closed-hub system and the waterproofing of catheter hub connections during showering. Rates of CR-BSI before and after implementing preventive measures were compared with respect to medication administered and type of bacterial infection.
RESULTS: Fifty patients received intravenous prostanoid therapy for a total of 41,840 catheter-days. The rate of CR-BSI during the study period was 0.51 infections per 1,000 catheter-days for epoprostenol and 1.38 infections per 1,000 catheter-days for treprostinil, which differed significantly (P < .01). CR-BSIs caused by gram-negative pathogens occurred more frequently with treprostinil than with epoprostenol (0.91 infections per 1,000 catheter-days vs 0.08 infections per 1,000 catheter-days; P < .01). Patients treated with treprostinil after the implemented changes had a significant decrease in CR-BSI rate (1.95 infections per 1,000 catheter-days vs 0.19 infections per 1,000 catheter-days; P < .01).
CONCLUSION: The closed-hub system and the maintenance of dry catheter hub connections significantly reduced the incidence of CR-BSI (particularly infections caused by gram-negative pathogens) in patients receiving intravenous treprostinil. | | Language | eng | | Pub Type(s) | Journal Article
