Implementation of an antibiotic allergy evaluation and testing program has been shown to increase the use of first-line antibiotics and can be cost saving.

Antibiotic allergies have significant clinical consequences, especially in immunocompromised populations. Evaluation of these allergies to prevent the avoidance of first-line antibiotics should be a standard part of the workflow for these patients, prior to transplant. Programs can be tailored to the available personnel and resources of the organization.

We aimed to review the current state, challenges, and needs of antimicrobial stewardship programs (ASPs) in adult solid organ transplantation (SOT) centers in Israel.

We conducted a survey using electronic questionnaires sent during February 2022 to infectious disease (ID) consultants of SOT centers, encompassing general and organ-specific ASP issues.

All six centers performing adult SOTs in Israel participated. The institutional ASPs in all centers included SOT recipients, and five centers had specific stewardship activities targeting SOT recipients. ASP activities were performed by ID consultants in all centers, with clinical pharmacists in most. ASP protocols and activity scope were highly variable. Formulary restriction with pre-authorization was used in all centers. Antibiotic allergy was addressed in ASP guidelines in half of the centers. Peri-transplantation antibiotic, antifungal, and antiviral prophylactic regimens varied based on center, transplanted organ, and patient risk group. Approaches tational collaborative program including all SOT centers.

Prolonged antibiotics are associated with toxicity, selection for resistant organisms, and secondary infections such as Clostridioides difficile colitis. Emerging clinical data suggest that short courses of antibiotics can be used for common bacterial infections among immune competent patients, but for many randomized controlled trials (RCTs), immunocompromised patients, including solid organ transplant recipients (SOTRs), have been excluded.

Peer-reviewed publications were identified through PubMed and Embase searches.

We review data examining shorter antibiotic courses among immunocompetent and immunocompromised patients and the rationale for use of short antibiotic courses in SOTRs.

There are known harms associated with antibiotics and, when studied, existing data do not demonstrate harm associated with shorter courses of antibiotics among SOTRs. Furthermore, several RCTs did include some immune compromised patients and found shorter therapy to result in similar clinical efficacy with diminished adverse effects. Shorter antibiotic durations should be considered in SOTRs, and questions of antibiotic duration among SOTRs should be prioritized for study in clinical trials.

The incidence of multidrug resistant organisms (MDROs) infections among solid organ transplant (SOT) patients is very high in Brazil.

This review will discuss antimicrobial use and resistance in SOT in Brazil, highlighting the main barriers and facilitators for implementation of an antimicrobial stewardship programme (ASP).

The most common group of MDROs is carbapenem-resistant Gram-negative bacteria and vancomycin-resistant Enterococcus. Carbapenem-resistant Enterobacterales (CREs) are the most frequent MDROs and have been reported as donor-derived as well. Although ASPs are mandatory in the country, there is a lack of information regarding ASPs in SOT recipients. The main barriers for the implementation of ASPs in Brazilian hospitals are lack of electronic medical records, absence of national guidelines specific to SOT recipients, lack of recommendations on surveillance culture to evaluate colonization and transmission of donor-derived MDROs, limited availability of rapid diagnostic tests, and insufficient pharmacist and clinician time allocated to ASP activities in some SOT centers.

The incidence of MDRO infections caused mainly by VREs and CREs is very high in the country. There is limited data regarding antimicrobial use among SOT recipients in Brazil. The absence of antimicrobial stewardship national guidelines specific to SOT recipients is one of the main barriers for the implementation of ASPs in Brazilian hospitals.

Diagnostic stewardship in solid organ transplant (SOT) recipients has the potential to help these vulnerable patients at risk for over-testing and overtreatment.

Herein, we review potential targets for diagnostic stewardship in SOT, such as Clostridioides difficile testing, urine cultures, molecular diagnostics, as well as novel areas of diagnostic stewardship.

Bundled interventions focused on appropriate C. difficile testing can result in a significant decrease in testing and clinical diagnosis of C. difficile infection without any harms related to delay in diagnosis. In otherwise stable renal transplant recipients after the first month of transplant, screening urine cultures have not been shown to improve outcomes. Novel targets that require additional study in the SOT population include noninvasive fungal diagnostics and cytomegalovirus testing strategies CONCLUSIONS Diagnostic stewardship is an innovative approach to improve diagnosis and limit unnecessary antimicrobial use. While there has been lithile there has been little direct exploration of diagnostic stewardship in the SOT population, there is great potential for benefit given frequent testing with diagnostics that have imperfect sensitivity and specificity, and sometimes great cost. Diagnostic stewardship in the SOT population is indeed possible but will require a multidisciplinary effort to ensure that appropriates tests and benefits are realized.

Antimicrobial stewardship (AMS) is a coherent set of actions to optimize antimicrobial use, improve patient outcomes, and reduce antimicrobial resistance (AMR). Thailand's national strategic plan has included AMS since 2017. Due to an increased risk of infection and AMR, solid organ transplant (SOT) recipients can benefit from antimicrobial stewardship programs (ASPs). However, the AMS in SOT has not been well defined. Balancing ASPs with the need for early and frequent antimicrobial treatment in this population is challenging. This review assesses the barriers and potential strategies of AMS in SOT in the setting of Thailand.

We used PubMed to identify published articles on AMS in organ transplantation in Thailand from January 2013 to January 2022. We also searched local literature and local data from Google Scholar and Google. Finally, we described the AMS experience at Ramathibodi hospital as a proxy for transplant centers in Thailand.

There was no specific article on AMS in SOT in Thailand. At our hospital, ASPs have been part of the hospital's routine patient care, including the practice in the transplant unit. Modifiable challenges to AMS in SOT include prescriber opposition, diagnosis uncertainty, and lack of high quality. Both systems and individualized approaches should be implemented to overcome these barriers. ML264 price The potential interventions include shortening antibiotic time-out, updating clinical guidelines, continuing education, handshake ASP, adopting new technology, and further research.

There are limited data on AMS in organ transplantation in Thailand. Strategic priorities should focus on modifiable barriers tailored to organ transplantation. Quality improvement should be ensured by process and outcome measures.

ASPs have largely been underutilized in solid organ transplant programs, and the current state of ASPs in transplantation is reviewed. Continued implementation of ASPs would likely significantly benefit transplant patients. Furthermore, coupling ASPs with robust programmatic metrics (such as transplant-specific NSQIP) will hopefully lead to improved outcomes including morbidity and mortality of solid organ transplant recipients.

Antimicrobial stewardship in solid organ transplant (SOT) recipients is important to prevent antimicrobial-associated complications, but traditional stewardship principles are challenging to implement for SOT patients. Newer methodologies to optimize stewardship efforts are needed.

PubMed was searched using the keywords "cell free DNA," "metagenomic sequencing," "host biomarker," "antimicrobial stewardship," and "SOT."

Metagenomic sequencing of cell free DNA has the potential to be a stewardship tool for SOT recipients. Various studies have shown its use for antimicrobial de-escalation and duration shortening. Host gene expression profiles can differentiate between infectious and noninfectious syndromes and may assist in stewardship efforts. However, information in immunocompromised hosts is conflicting.

Microbial cell free DNA sequencing and host gene expression profiling show promise as stewardship tools in SOT recipients. Future studies on antimicrobial stewardship in SOT recipients should focus on their clinical use and feasibility.

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.

A literature search for the terms "antifungal stewardship" and "solid-organ transplant" revealed a small evidence base to support AFS programs in this patient group.

There is significant overlap in the methodology used in AMS and AFS programs, with notable differences in diagnostics, which are discussed in detail. The primary AFS interventions tested in SOT recipients are implementation of clinical guidelines and care bundles, digital enablers of AFS, and post-prescription review/audit and feedback.

There is an urgent need for further research to support effective AFS strategies in this highly susceptible population.
