The pre-transplant evaluation: Considerations for trainees and early career transplant infectious diseases clinician.

Transplant infectious disease (TID) clinicians are integral to the pre-transplantation evaluation. Pre-transplant evaluations allow clinicians to assess risk factors for latent infections and relevant exposures to potential pathogens, address immunizations, and optimize patients' health and understanding of life after transplant. However, there is not a standardized approach to the pre-transplant evaluation. This article reviews the details of performing successful pre-transplant evaluations, including updated recommendations on available vaccines and contemporary opinions on marijuana use. This resource can be used for teaching with trainees or for early career TID clinicians.

The nuts and bolts of transplant infectious disease training.

The number of transplant infectious disease (TID) fellowship programs has expanded rapidly in the past 5 years, with the creation of many new programs and the expansion of training tracks and dedicated years as the demand for TID physicians grows drastically. This editorial focuses on major factors and complexities that programs should consider in TID fellowship creation, as well as highlighting examples of formative experiences, programmatic structure, and fellow resources that trainees can use to identify their desired career path in TID.

Beginners guide to protocol writing in transplant infectious diseases.

Creating protocols surrounding the guidance of the prevention and treatment of infections in transplantation is an integral part of being a transplant infectious disease physician. This piece outlines the key components for success in developing a protocol, with an example protocol and protocol template available for readers. Collaborating effectively within the multi-disciplinary team to develop, implement, and assess the efficacy of a protocol is a skill that enhances the relationship with our transplantation colleagues and improves patient outcomes by standardizing the care delivered.

Road map to success: Advice for transplant infectious diseases job interviews, negotiation, and early career development.

"They paged me what?": A transplant infectious disease guide to donor calls.

Donor-derived infections in solid organ transplantation can be prevented by risk stratification of donors based on available information, and inquiries surrounding possible or diagnosed infection are common questions posed to transplant infectious disease subspecialists. This article outlines the five key steps in addressing a donor call from a transplant team in a systematic approach, focusing on donor and recipient-specific factors, transmissibility and treatment of possible infections, and the likelihood of a patient's future organ offers and mortality remaining on the waitlist. These principles are then applied to five donor call cases, in which we review the key takeaway points and supporting literature. These cases can be used as a resource for teaching with trainees.

Safety and value of pretransplant antibiotic allergy delabeling in a quaternary transplant center.

BACKGROUND: Self-reported antibiotic allergies, also known as antibiotic allergy labels, are common and may lead to worse patient outcomes. Within immunocompromized patients, antibiotic allergy labels can lead to inappropriate use of antimicrobials and may limit options for prophylactic and therapeutic options in the posttransplant period. While antibiotic allergy delabeling is considered an important aspect of antibiotic stewardship protocols, evidence and awareness of its application in transplant recipients is limited. METHODS: We describe our experience with an antibiotic allergy delabeling intervention in the pretransplant evaluation period and its impact on posttransplant antimicrobial utilization. This was a retrospective analysis of patients with an antibiotic allergy label who underwent evaluation for solid organ or stem cell transplantation between 2015 and 2020. Patients included in this analysis were those who completed pretransplant antibiotic allergy delabeling through our Drug Allergy Clinic and were retained in care for 6 months after transplant. RESULTS: Twenty-six of 27 patients underwent pretransplant antibiotic allergy delabeling and safely received the delabeled antibiotic posttransplant. There were no reported side effects to the delabeled antibiotic within 6 months posttransplant. Specific examination of sulfonamide (sulfa)-antibiotic delabeling showed cost savings of $254 to $2910 per patient in the posttransplant period compared to the use of alternative antibiotics for prophylaxis protocol. CONCLUSION: Antibiotic allergy delabeling prior to transplant is safe, is of high value, and should be considered in the pretransplant evaluation period. More resources are needed for the development of delabeling guidelines and support for broad implementation of pretransplant antibiotic allergy delabeling programs.

The impact of earthquakes in Latin America on the continuity of HIV care: A retrospective observational cohort study.

Objectives: As earthquakes occur frequently in Latin America and can cause significant disruptions in HIV care, we sought to analyze patterns of HIV care for adults at Latin American clinical sites experiencing a significant earthquake within the past two decades. Study design: Retrospective clinical cohort study. Methods: Adults receiving HIV care at sites experiencing at least a "moderate intensity" (Modified Mercalli scale) earthquake in the Caribbean, Central and South America network for HIV epidemiology (CCASAnet) contributed data from 2003 to 2017. Interrupted Time Series models were fit with discontinuities at site-specific earthquake dates (Sept. 16, 2015 in Chile; Apr. 18, 2014 and Sept. 19, 2017 in Mexico; and Aug. 15, 2007 in Peru) to assess clinical visit, CD4 measure, viral load lab, and ART initiation rates 3- and 6-months after versus before earthquakes. Results: Comparing post-to pre-earthquake periods, there was a sharp drop in median visit (incidence rate ratio [IRR] = 0.79, 95% confidence interval [CI]: 0.68-0.91) and viral load lab (IRR = 0.78, 95% CI: 0.62-0.99) rates per week, using a 3-month window. CD4 measurement rates also decreased (IRR = 0.43; 95% CI: 0.37-0.51), though only using a 6-month window. Conclusions: Given that earthquakes occur frequently in Latin America, disaster preparedness plans must be more broadly implemented to avoid disruptions in HIV care and attendant poor outcomes.

Opportunities for Antimicrobial Stewardship Interventions Among Solid Organ Transplant Recipients.

Although antimicrobial stewardship programs have excelled over the past decade, uptake and application of these programs to special populations such as solid organ transplant recipients have lagged. Here, we review the value of antimicrobial stewardship for transplant centers and highlight data supporting interventions that are ripe for adoption. In addition, we review the design of antimicrobial stewardship initiatives, targets for both syndromic and system-based interventions.

Development and implementation of "handshake rounds": An antibiotic stewardship intervention for hospitalized adult patients with hematologic malignancies.

Objective: To design and implement "handshake rounds" as an antibiotic stewardship intervention to reduce inpatient intravenous (IV) antibiotic use in patients with hematologic malignancies. Design: Quasi-experimental analysis of antibiotic use (AU) and secondary outcomes before and and after handshake rounds were implemented. Setting: Quaternary-care, academic medical center. Patients: Hospitalized adults with hematologic malignancies receiving IV antibiotics. Methods: We performed a retrospective review of a preintervention cohort prior to the intervention. A multidisciplinary team developed criteria for de-escalation of antibiotics, logistics of handshake rounds, and outcome metrics. Eligible patients were discussed during scheduled handshake rounds between a hematology-oncology pharmacist and transplant-infectious diseases (TID) physician. Prospective data were collected over 30 days in the postintervention cohort. Due to small sample size, 2:1 matching was used to compare pre- to and postintervention AU. Total AU in days of therapy per 1,000 patient days (DOT/1,000 PD) was reported. Mean AU per patient was analyzed using Wilcoxon rank-sum test. A descriptive analysis of secondary outcomes of pre- and postintervention cohorts was performed. Results: Total AU was substantially lower after the intervention, with 517 DOT/1,000 PD compared to 865 DOT/1,000 PD before the intervention. There was no statistically significant difference in the mean AU per patient between the 2 cohorts. There was a lower rate of 30-day mortality in the postintervention cohort and rates of ICU admissions were similar. Conclusions: Conducting handshake rounds is a safe and effective way to implement an antibiotic stewardship intervention among high-risk patient population such as those with hematologic malignancies.

Antimicrobial de-escalation in patients with high-risk febrile neutropenia: Attitudes and practices of adult hospital care providers.
