Application of cost-effectiveness methodology to the consideration of needlestick-prevention technology

Data from the study of needlestick-prevention devices in 10 New York State hospitals enabled application of cost-effectiveness analysis techniques for determining relative benefits of various safety interventions. This article introduces to infection control practitioners several economic concepts related to cost-effectiveness methodology and provides two examples of how they may be applied for decision-making purposes. A critical aspect of the analysis described is the determination of a base cost of needlestick injury. By applying decision analysis to experience-based data aggregated from participating institutions, base expected cost of needlestick injury was determined to be $363.
