The Workshop

The workshop agenda consisted of three major components: (1) resistance as a phenomenon and the major factors contributing to its increasing prevalence; (2) surveillance activities and needs; and (3) options for response. Its primary objectives were to extract those aspects of resistance that seemed most pressing, to inspect the potential of new scientific advances to spur needed diagnostic and therapeutic advances, and to examine areas of intervention most likely to return the biggest payback to investments of funding, research, advocacy, and education. A compendium of currently active systems that include surveillance of antimicrobial resistance is provided in Appendix A. Appendix B presents the outline of the global and national resistance surveillance system proposed in 1995 by the American Society for Microbiology (ASM) Task Force. Appendix C is a glossary. Appendix D contains the workshop agenda and participants list.

THE COSTS OF ANTIMICROBIAL RESISTANCE*

Background

Before proceeding to discuss the major categories of concern relative to antimicrobial resistance—that is, issues of surveillance, the potential offerings of new scientific developments, and the range of possible responses to the problem—workshop participants considered the costs of resistance. These costs can include such factors as the direct cost of time in a hospital, extra physicians' visits when antibiotics are ineffective, extra hospital days and hospitalizations due to community-acquired resistant infections, the costs of newer antibiotics to replace antibiotics to which bacteria have become resistant, and lost workdays and deaths.

The one study to date that has taken all of these factors into account used mathematical models to estimate the costs of resistance, including the effect of a resistant infectious agent that appears in one year on the cost to society in later years.3 Depending on whether or not death was a consequence, this study determined that in then-current dollars, the total societal costs of antibiotic resistance ranged from $150 million (without deaths) to $3 billion (with deaths) annually in the United States.

In 1990, the National Foundation for Infectious Disease estimated that the costs only of nosocomial (hospital-acquired) infections caused by antibiotic-resistant bacteria could be as high as $4 billion annually. The Centers for Disease Control and Prevention (CDC) estimated these costs at $4.5 billion when costs from both antibiotic-resistant and susceptible infections were included. In 1992,
