As a heart transplant recipient for 34 years, I have been asked to write an experience-based opinion on antibiotic stewardship programs (ASPs) in the transplant setting. The aim of this piece is to provide real-life examples—the good, the bad, and the ugly—to help contextualize the potential impact of an effective transplant-specific ASP model. The exigency of transplant ASPs is illuminated, and suggested changes that can help patients right away are provided.

Antimicrobial stewardship programs (ASPs) have made immense strides in optimizing antibiotic, antifungal, and antiviral use in clinical settings. However, although ASPs are required institutionally by regulatory agencies in the United States and Canada, they are not mandated for transplant centers or programs specifically. Despite the fact that solid organ transplant recipients in particular are at increased risk of infections from multidrug-­resistant organisms, due to host and donor...

Background Antimicrobial stewardship (AMS) aims to optimize antimicrobial use. Auditing and reporting of antimicrobial prescribing are essential. Auditing tools for solid organ transplant (SOT) patients should tailor to their needs. Methods We reviewed published data describing auditing tools in the general and SOT population. Results We focused on three internationally or nationally available auditing tools. The National Antimicrobial Prescribing Survey (NAPS) is web-based tool to report...

Antimicrobial therapies are essential tools for transplant recipients who are at high risk for infectious complications. However, judicious use of antimicrobials is critical to preventing the development of antimicrobial resistance. Treatment of multidrug-resistant organisms is challenging and potentially leads to therapies with higher toxicities, intravenous access, and intensive drug monitoring for interactions. Antimicrobial stewardship programs are crucial in the prevention of...

Background Over 1000 solid-organ and close to 2000 stem-cell transplants are performed annually in Australia. Methods Antimicrobial stewardship activities in transplant units in Australia were reviewed. Results All health service organizations, and thus all transplant centers, in Australia are required to have an antimicrobial stewardship program. Despite this, in one recent survey, 23.5% of hospital antibiotic prescriptions were inappropriate. Vigorous efforts are being made to implement...

Background Several molecular platforms now exist for early detection of infectious pathogens. In this review, we present the currently available literature summarizing clinical outcomes using rapid diagnostic tests (RDTs) in the solid organ transplant (SOT) population. We also present potential benefits and drawbacks of these technologies for SOT patients. Methods We completed a PubMed search querying for 31 specific RDTs AND (“SOT”). We also queried PubMed for studies on RDT outcomes in the...

Antibiotic allergy labels (AALs) are commonly reported, with well-defined prevalence in the general population; several studies have now focused efforts on immunocompromised hosts. Understanding the prevalence of reported allergy labels and methods of antibiotic allergy evaluation and delabeling strategies has the potential to improve prescribing practices and clinical outcomes in this high-antibiotic use group. In this review, we will discuss the current literature on the prevalence,...

Background Antifungal stewardship (AFS) lags behind antimicrobial stewardship (AMS) in terms of implementation, evidence base, and workforce experience. Solid-organ transplantation (SOT) carries a significant risk of invasive fungal infection, with high associated mortality, and is therefore associated with significant opportunities to optimize antifungal use. Methods A literature search for the terms “antifungal stewardship” and “solid-organ transplant” revealed a small evidence base to...

Objective: To evaluate the change in vancomycin days of therapy (DOT) and vancomycin-associated acute kidney injury (AKI) after an antimicrobial stewardship program (ASP) intervention to decrease vancomycin use in stable patients after hematopoietic stem cell transplantation (HSCT). Design: Retrospective cohort study and quasi-experimental interrupted time series analysis. Change in unit-level vancomycin DOT per 1,000 inpatient days after the intervention was assessed using segmented Poisson...

SOT recipients are more vulnerable to infections with antimicrobial-resistant organisms, and therefore, it may be useful for transplant centers to create transplant-specific antibiograms to direct empirical antimicrobial regimens and monitor trends in antimicrobial resistance. SOT-specific antibiograms were created using antimicrobial susceptibility data on isolates from 2012 to 2018 at The Hospital for Sick Children, Toronto, Ontario, Canada. The CLSI guidelines were followed to generate...

Objective: Viruses are more common than bacteria in patients hospitalized with community-acquired pneumonia. Little is known, however, about the frequency of respiratory viral testing and its associations with antimicrobial utilization. Design: Retrospective cohort study. Setting: The study included 179 US hospitals. Patients: Adults admitted with pneumonia between July 2010 and June 2015. Methods: We assessed the frequency of respiratory virus testing and compared antimicrobial utilization,...

Antimicrobial stewardship is an essential component of transplant programs to improve patient outcomes, reduce the threat of antimicrobial resistance, and lower the risk of drug toxicity. A multidisciplinary approach that leverages the existing team-based infrastructure of transplant programs and encompasses partnership with pharmacy, infection prevention, and microbiology is important for successful implementation. This chapter outlines the importance of stewardship in transplantation,...

In recent years, the global public health community has increasingly recognized the importance of antimicrobial stewardship (AMS) in the fight to improve outcomes, decrease costs, and curb increases in antimicrobial resistance around the world. However, the subject of antifungal stewardship (AFS) has received less attention. While the principles of AMS guidelines likely apply to stewarding of antifungal agents, there are additional considerations unique to AFS and the complex field of fungal...

PURPOSE: Inappropriate vancomycin for febrile neutropenia (FN) is an ideal antimicrobial stewardship target. To improve vancomycin prescribing, we instituted a multifaceted intervention, including an educational guideline with audit for compliance; an antibiotic use audit; and an assessment of local burden of methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection. MATERIALS AND METHODS: We conducted a quasi-experimental pre-post intervention review of vancomycin...

These guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of post‐operative surgical site infections (SSIs) in solid organ transplantation. SSIs are a significant cause of morbidity and mortality in SOT recipients. Depending on the organ transplanted, SSIs occur in 3%‐53% of patients, with the highest rates observed in small bowel/multivisceral, liver, and pancreas transplant recipients....

Caring for immunocompromised patients is challenging. Despite significant advances, infection remains a major cause of morbidity and mortality, and as such, these patients are frequently exposed to antimicrobial agents. Antimicrobial stewardship programs (ASPs) can assist transplant centers in optimizing antibiotic usage, particularly in this age of growing microbial resistance and the scarcity of new anti-infective agents in development. The collaborative approach of antimicrobial...
