Case Study #3: Antimicrobial Resistance: Clinical Countermeasures

Faculty

Needs Statement

Drug resistant organisms have increased across the globe and represent a major threat to the health of hospitalized patients. Overuse and improper use of certain antibiotic drug classes as well as failure to take infection control measures in hospitals has led to a major nosocomial infection problem in the United States. Antimicrobials account for upwards of 30% of hospital pharmacy budgets. It has been recognized for several decades that up to 50% of antimicrobial use is inappropriate, adding considerable cost to patient care. In addition to direct pharmacy acquisition costs, numerous reports suggest that inappropriate and unnecessary antimicrobial use leads to increased selection of resistant pathogens. Once antimicrobial resistance emerges, it can have a significant impact on patient morbidity and mortality, as well as increased health care costs.

The emergence of infections with multidrug-resistant gram-negative organisms, combined with a paucity of new drug development, has unfortunately led to the resurgent use of colistin, a polymyxin antimicrobial previously abandoned because of its high rates of nephrotoxicity and neurotoxicity. In 1998, the Institute of Medicine estimated that the annual cost of infections caused by antimicrobial-resistant bacteria was $4–$5 billion. Reducing the risk of health care acquired infection is one of seven 2004 National Patient Safety Goals set by JCAHO.

Evaluation of the literature suggests certain knowledge gaps may exist among hospital-based practitioners regarding the magnitude and growth of antibiotic resistance within hospitals, how to effectively limit resistance, how to treat patients infected with resistant pathogens, following appropriate infection control practices, and choosing appropriate treatment options for patients with resistance risk factors. A recent physician survey concluded that although most physicians view antibiotic resistance as a serious national problem, perceptions about its local importance, its causes, and possible solutions vary more widely. Disparities in physician knowledge, beliefs, and attitudes may compromise efforts to improve antibiotic prescribing and infection control practices.

Objectives

1. Explain the foundation and components of the SCIP Partnership Initiative and National Goal;
2. Describe the impact of surgical care complications as it relates to postoperative infections for the nation’s healthcare patient population;
3. Discuss antibiotic recommendations, such as timing, selection, and duration, for patients undergoing select surgical procedures;
4. Describe the importance of the surgeon’s role in a successful antimicrobial stewardship program; and
5. Review the CDC’s 12 steps to prevent antimicrobial resistance among surgery patients.
