BLOOM: Pragmatic Feasibility Trial
Mayo Clinic
Summary
The goal of this study is to compare two different ways of dosing cefepime, an antibiotic for very sick patients - the usual approach to dosing or a new dosing method. The new dosing method uses only doses that are available in normal care, but choosing between the different doses is based on more information about the patient's body including their kidney function. The primary purpose of this study is to test how easy it is for healthcare professionals to use the new dosing method and how best to conduct the trial. The study will also assess if the new dosing method helps patients recover faster and reduces side effects.

Interventions
- OtherUp-front individualized dosing algorithm
An individualized cefepime dosing algorithm will be used to determine the cefepime dose and interval. The dose recommendation will be provided using the EHR-prompts to the clinical care team and ordered and/or verified by the ICU pharmacist using an established collaborative practice agreement. As a pragmatic trial, at any point care teams may modify the empiric or subsequent dose based on their clinical judgement.
- OtherUsual Care
The standard of care group will receive empiric dosing guided by an institutional antimicrobial guide. Cefepime is typically dosed at 0.5-2 g every 8-24 h according to categorical thresholds of estimated creatinine clearance (eGFRcr). Cystatin C and eGFRcr-cys can be calculated and used at clinicians' discretion to aid in drug dose determination.
