In this episode, I’ll discuss an abstract by a pharmacy resident about the use of a combination antibiotic bag (CAB) in severe sepsis and septic shock.
At the NYSCHP annual assembly, I saw a presentation about a novel way to increase compliance with the sepsis core measure bundle of antibiotics and 30 ml/kg of crystalloid fluids for septic shock.
The primary author of this investigation is Michael Lorenzo, and he agreed to join me on the podcast to discuss his intervention. Pharmacy Mike is a Doctor of Pharmacy and PGY-1 resident at Upstate University Hospital in Syracuse, NY.
Below is a summary of his abstract – listen to the episode to hear the full interview!
Impact of a Combination Antibiotic Bag on Compliance with Surviving Sepsis Campaign Goals in Emergency Department Patients with Severe Sepsis and Septic Shock
Lorenzo M, MacConaghy L, Meola G, Miller C, Pratt B, Steele J, Probst L, Seabury R
The authors sought to determine whether the use of a combination antibiotic bag (CAB) of 2 grams cefepime plus 1 gram vancomycin mixed in 1 liter of normal saline impacts compliance with quality measures related to antibiotics and fluids within 3 hours of presentation for patients with severe sepsis or septic shock.
This was a retrospective chart review in the ED of a single academic medical center. Patients receiving > 1 antibiotic were included if they met criteria for severe sepsis or septic shock.
The primary endpoint was the administration of two antibiotics and a 30 mL/kg crystalloid challenge within three hours of ED triage. The secondary endpoint was 14-day in-hospital mortality.
80 patients in the CAB group and 80 patients in the non-CAB group were included in this analysis. The CAB group met the primary outcome more frequently than the non-CAB group (63.8% vs. 22.5%). No difference in 14-day in-hospital mortality was noted although the CAB group trended towards a lower mortality rate compared to the non-CAB group (25% vs. 32.5%). The median time to administration of two antibiotics and the median time to administration of a 30 mL/kg crystalloid challenge were also shorter in the CAB group.
The authors concluded:
The CAB improved the proportion achieving guideline recommendations for crystalloid and antibiotic administration in a cohort of ED patients with severe sepsis or septic shock. Such an intervention has not been previously reported and could play a meaningful role in the management of severe sepsis and septic shock.
