The Impact of the Implementation of a Pharmacist-Driven Protocol of Second Dose Cefepime for Adult Patients With Sepsis in the Emergency Department at a Tertiary Care Academic Medical Center

Purpose: Prior literature evaluating the importance of timely second-dose antibiotics in patients with sepsis has led to better outcomes and a possible reduction in mortality, length of mechanical ventilation, and length of time requiring vasopressors. Objective: To evaluate the impact of a newly developed pharmacist-led two-dose cefepime protocol implemented within an emergency department (ED) service. Methods: This was a retrospective, single-center, pre-post observational cohort study. Institutional review board approval was obtained. The primary endpoint was a reduction in time between the first and the second doses of antibiotics for patients with sepsis who present to the emergency department. Secondary endpoints included length of vasopressor therapy, intensive care unit (ICU) length of stay, hospital length of stay, duration of mechanical ventilation, and mortality. Results: A total of 84 patients were included in the pharmacist-led two-dose hospital protocol and 79 patients were included in the historical control. In the control cohort, the median time between the first and second dose of antibiotics was 12 hours vs 8.5 hours in the tested cohort. The average time requiring vasopressors was 1.20 days for the control cohort vs.46 days for the post-implementation group. Lastly, the median hospital length of stay in days was 8 for the control group vs 7 for the tested cohort. Conclusion: Implementation of a pharmacist-led two-dose cefepime protocol was associated with a numerically lower duration between second-dose antibiotics, days requiring vasopressors, and a slight reduction in hospital length of stay.
