COVID-19 Outcomes Among Hematopoietic Cell Transplant and Chimeric Antigen Receptor T-Cell Recipients in the Era of SARS-CoV-2 Omicron Variants and COVID-19 Therapeutics.

Recipients of cellular therapies, including hematopoietic cell transplant (HCT) and chimeric antigen receptor T-cell (CART) therapy, are at risk for poor outcomes from coronavirus disease 2019 (COVID-19). There are limited data describing outcomes among patients in the pre- and early post-cellular therapy period during the Omicron era when multiple antiviral therapeutics were widely available. The objective of this study is to describe COVID-19 treatment and outcomes in patients diagnosed with COVID-19 during the pre- or early post-cellular therapy period.

Clinical outcomes and frequency of persistent infection among immunosuppressed patients treated with bebtelovimab for COVID-19 infection at an ambulatory cancer center.

Background: There are limited data on clinical outcomes associated with the use of bebtelovimab for the treatment of coronavirus disease 2019 (COVID-19) among cancer patients. We aimed to define the clinical characteristics and outcomes among patients receiving bebtelovimab as part of the COVID-19 therapeutics program at our cancer center.

Methods: This is a retrospective cohort study of immunosuppressed adult patients who received bebtelovimab at Fred Hutchinson Cancer Center between March 2022, and November 2022.

Analysis of health care facility-onset Clostridioides difficile infection (CDI) in a hematopoietic cell transplant (HCT) unit: A call for diagnostic stewardship in a complex patient population.

Nearly half the patients identified as having health care facility-onset Clostridioides difficile infections on a hematopoietic cell transplant unit had an alternative clinical explanation for diarrhea, including conditioning regimen toxicity or other medications. Our study supports that targeted diagnostic stewardship interventions should be explored and that additional risk-adjustments considered for facilities with oncology hematopoietic cell transplant wards in the National Healthcare Safety Network LabID Clostridioides difficile infection standardized infection ratio model.

Improving antimicrobial use through better diagnosis: The relationship between diagnostic stewardship and antimicrobial stewardship.

Antimicrobial stewardship programs (ASPs) exist to optimize antibiotic use, reduce selection for antimicrobial-resistant microorganisms, and improve patient outcomes. Rapid and accurate diagnosis is essential to optimal antibiotic use. Because diagnostic testing plays a significant role in diagnosing patients, it has one of the strongest influences on clinician antibiotic prescribing behaviors.

A single-institution experience with a brucellosis outbreak in the United States.

Human cases of brucellosis in the United States are primarily limited to imported infections or reservoirs. We describe a brucellosis outbreak involving 8 patients treated at a single hospital in the United States. Standardized precautionary microbiology processes and coordinated collaboration among hospital departments and local health departments assisted in optimally managing this disease at our institution.
