Antibiotic Management Program

Infections are a major complication of cancer treatment, so timely and appropriate antimicrobial therapy is critical for optimal patient outcomes. However, the large number of anti-infectives and the growing problem of microbial resistance have complicated prescribing. Establishing an antimicrobial stewardship program that can provide guidance and oversight of these medications in acute-care hospitals and other healthcare settings is increasingly encouraged.

Memorial Sloan Kettering has had an antibiotic management program (AMP) since 2001, which has the distinction of being one of New York City’s oldest antimicrobial stewardship programs. Susan Seo, an infectious disease (ID) physician and the program’s founding director, continues to lead the program. Other key members include full-time ID clinical pharmacists and a data manager. The AMP strives to ensure the optimal selection, dose, and duration of antimicrobials for effective treatment or prevention of infection while minimizing side effects and risk for subsequent resistance.

Prior approval and post-prescription review: The primary goal of this process is to provide a system for rapid and rational antibiotic approval. Review guarantees that each patient receives the appropriate therapy, including dosing and duration. The AMP also performs targeted reviews to reevaluate antimicrobial therapy based on clinical, laboratory, and microbiologic data that are collected during a patient’s hospital stay.

AMP website: The AMP maintains a website on the MSK intranet, which serves as a repository for all evidence-based antibiotic and antifungal guidelines that have been developed for the institution. This site serves as a valuable resource for hospital staff. Some of the guidelines developed in partnership with various departments include Outpatient Fever & Neutropenia, Surgical Prophylaxis, Allogeneic and Autologous HSCT Prophylaxis, and Pediatric Antimicrobial Drug Dosing.

Education: Education is an important component of antimicrobial stewardship. ID fellows have an opportunity to work with the AMP during their microbiology/AMP/infection control rotation during their first year. The AMP also gives talks related to antimicrobial stewardship within the institution.

IDSNY Pre-Meeting Workshop for ID Fellows: Since 2013, AMP Director Susan Seo has been co-director for the Infectious Disease Society of New York (IDSNY) pre-meeting workshop on antimicrobial stewardship and infection control, which is held each spring. This is a half-day course created in partnership with Montefiore Medical Center for regional ID fellows. The program consists of interactive case-based learning in which solutions are discussed in an open forum among ID fellows and a local panel of experts from up to 12 area hospitals. The opportunity to supplement training in antimicrobial stewardship and infection control as well as to meet well-recognized experts in both fields has led to positive response from past attendees.

Research: The AMP works collaboratively with Infection Control, Clinical Laboratory Medicine, Pharmacy, IT, and various medical and surgical oncology services. Areas of clinical research include investigating stewardship methods to optimize antimicrobial use (such as a multicenter study evaluating post-prescription review and feedback), studying the relationship between antimicrobial exposure and clinical outcomes, and looking at the interplay between microbiologic testing and antimicrobial prescribing. Past ID fellows have worked with the AMP on stewardship-related projects and have presented their findings at local and national meetings. Incoming and current fellows, as well as other trainees, are welcome to engage in research projects with the AMP.
