Is Greater BSA Use for Sepsis, Bacteremia Affecting HO-CDIs?



Studying the impact of antibiotics for sepsis is difficult due to the multiple confounding factors, such as severity of illness, time to diagnosis, length of stay, and availability of adequate control groups. Current evidence suggests that antibiotic selection for sepsis can have a severe impact on the rate of CDIs. Vancomycin and piperacillin/tazobactam appear to be low-risk antibiotics for the development of CDIs, whereas cephalosporins and fluoroquinolones carry a much greater risk. Use of BSAs for sepsis requires a delicate balance between appropriate empiric therapy and prevention of CDIs. Further studies are needed to quantify the risks associated with antibiotic use in sepsis, identify patients at greatest risk of CDIs, and establish effective de-escalation practices.
