Abstract/OtherAbstract:
BACKGROUND: Hemodialysis (HD) tunneled cuffed catheters may be fitted with neutral-valve closed-system connectors. Such connectors, which are flushed with saline solution and used for 3 consecutive HD sessions, provide a mechanically closed positive-pressure barrier and potentially may be useful to prevent catheter-related bacteremia and dysfunction. STUDY DESIGN: Single-center randomized controlled trial. SETTING & PARTICIPANTS: 66 adult HD patients with a tunneled cuffed catheter. INTERVENTION: Neutral-valve closed-system connector (Tego Needlefree Hemodialysis Connector) versus trisodium citrate, 46.7%, locking solution (Citra-Lock; control group). OUTCOMES: Primary composite outcome was the incidence rate of catheter-related dysfunction or bacteremia. Secondary outcomes were the separate incidence rates of catheter-related dysfunction and bacteremia and the cost of both procedures. MEASUREMENTS: Catheter dysfunction was defined as the requirement of urokinase and/or a mean blood flow ≤250 mL/min during 2 consecutive HD sessions. Catheter-related bacteremia was defined as ≥2 positive blood cultures. Time of catheter use was calculated and the incidence rate of complications was expressed per 100 person-years. RESULTS: 66 patients were followed up for a median of 86 (IQR, 29-200) days. The composite primary outcome was not significantly reduced in the closed-system-connector intervention group versus the citrate-locking-solution control group (63.56 vs 71.51 per 100 person-years; P = 0.3). Catheter dysfunction in the intervention group was not decreased versus controls (59.59 vs 51.64 per 100-person-years; P = 0.9). Only 6 catheter-related bacteremia events were identified, one in the intervention group (3.97 vs 19.86 per 100 person-years; P = 0.06). LIMITATIONS: Small size of the patient population and single-center study. CONCLUSIONS: Superiority of the closed-system connector in terms of prevention of the primary efficacy end point compared to the standard locking solution was not observed. Further evaluation in a larger study is suggested.
