At the end of the data collection period, a panel compromising of a pharmacy resident, antimicrobial stewardship pharmacist, nephrology pharmacist, nurse practitioner and nephrologist will adjudicate each antimicrobial prescription with a presumed indication for congruence with available clinical guidelines and antimicrobial principles described by CDC. Each antimicrobial regimen will be categorized as congruent or non-congruent; any regimen for which there is inadequate or unavailable documentation in support of congruence will be classified as unknown congruence. The primary tool for assessing antimicrobial therapy will be against antimicrobial stewardship best practices guiding principles established by CDC, supplemented by applicable guidelines for each site of suspected infection published by major infectious disease and nephrology societies. Evidence-based resources for drug dosing in renal failure will be used to determine whether the prescribed antimicrobial regimen is consistent with literature-based dosing recommendations. The prescription will be assessed for types of stewardship-discordant prescribing that will be defined based on general stewardship principles a priori such as the following:
