EVALUATION OF THE COSTS AND BENEFITS OF REDUCING HOSPITAL INFECTION

The techniques of economic evaluation have now been widely applied in health care. These techniques assess the value for money from interventions by comparing their costs and consequences. Since measures to reduce hospital infection normally result in costs they should, in principle, be subjected to economic evaluation. This paper outlines the essential elements of economic evaluation and distinguishes between different forms of analysis. It also discusses a number of evaluations of infection control measures undertaken to date. The recurring methodological weaknesses in current studies are identified and improvements suggested. Finally, the practical relevance of such studies in the current cost-conscious health care environment is discussed. © 1991.
