PK –PD Compass: bringing infectious diseases pharmacometrics to the patient’s bedside

AbstractAntimicrobial stewardship programs face many challenges, one of which is a lack of guidance regarding antimicrobial dose, interval, and duration. There is no tool that considers patient demographic, pathogen susceptibility, and pharmacokinetic –pharmacodynamic (PK–PD) targets for efficacy in order to evaluate appropriate antimicrobial dosing regimens. The PK–PD Compass, an educational mobile application, was developed to address this unmet need. The application consists of a Monte Carlo simulation algorithm which integrates pharmaco kinetic (PK) and PK–PD data, patient-specific characteristics, and pathogen susceptibility data. Through the integration of these data, the application allows practitioners to assess the percent probability of PK–PD target attainment for 35 intravenous antimicrobial agents across 29 infection ca tegories. Population PK models for each drug were identified, evaluated, and refined as needed. Susceptibility breakpoints were based upon FDA and CLSI criteria. By incorporating these data into one interface, clinicians can select the infection, pathogen, and antimicrobial agents of interest and ob tain the percent probability of PK–PD target attainment for each regimen based upon patient-specific characteristics. The antimicrobial dosing regimens provided include those recommended by standard guidelines and reference texts. However, unlike these references, potential choices are prioritized based on percent probabilities of PK–PD ta...
