  • Title: Cost-effectiveness of antiseptic-impregnated central venous catheters for the prevention of catheter-related bloodstream infection.
    Author: Veenstra DL, Saint S, Sullivan SD.
    Journal: JAMA; 1999 Aug 11; 282(6):554-60. PubMed ID: 10450717.
    Abstract:
    CONTEXT: A recent randomized controlled trial and meta-analysis indicated that central venous catheters impregnated with an antiseptic combination of chlorhexidine and silver sulfadiazine are efficacious in reducing the incidence of catheter-related bloodstream infection (CR-BSI); however, the ultimate clinical and economic consequences of their use have not been formally evaluated. OBJECTIVE: To estimate the incremental clinical and economic outcomes associated with the use of antiseptic-impregnated vs standard catheters. DESIGN: Decision analytic model using data from randomized controlled trials, meta-analyses, and case-control studies, as well as safety data from the US Food and Drug Administration. SETTING AND PATIENTS: A hypothetical cohort of hospitalized patients at high risk for catheter-related infections (eg, patients in intensive care units, immunosuppressed patients, and patients receiving total parenteral nutrition) requiring use of a central venous catheter. INTERVENTION: Short-term use (2-10 days) of chlorhexidine-silver sulfadiazine-impregnated multilumen central venous catheters and nonimpregnated catheters. MAIN OUTCOME MEASURES: Expected incidence of CR-BSI and death attributable to antiseptic-impregnated and standard catheter use; direct medical costs for both types of catheters. RESULTS: In the base-case analysis, use of antiseptic-impregnated catheters resulted in a decrease in the incidence of CR-BSI of 2.2% (5.2% for standard vs 3.0% for antiseptic-impregnated catheters), a decrease in the incidence of death of 0.33% (0.78% for standard vs 0.45% for antiseptic-impregnated), and a decrease in costs of $196 per catheter used ($532 for standard vs $336 for antiseptic-impregnated). The decrease in CR-BSI ranged from 1.2% to 3.4%, the decrease in death ranged from 0.09% to 0.78%, and the costs saved ranged from $68 to $391 in a multivariate sensitivity analysis. CONCLUSION: Our analyses suggest that use of chlorhexidine-silver sulfadiazine-impregnated central venous catheters in patients at high risk for catheter-related infections reduces the incidence of CR-BSI and death and provides significant saving in costs. Use of these catheters should be considered as part of a comprehensive nosocomial infection control program.
