When we initiate the sepsis bundle in the ED for patients with suspected sepsis, what probability that those patients who received broad spectrum antibiotics in the ED would have bacterial infection.
This study (Shappell et al) provides us with a glimpse of those number.
Settings: Retrospective study of adults presenting to 4 EDs in Massachusetts.
Patients: patients with suspected serious bacterial infection in ED, defined as blood cultures and initiation of at least one broad spectrum antibiotics. Random selection of 75 patients per hospital.
Patients were categorized in 4 groups:
Outcome: Prevalence of each category.
Study Results: 300 patients who received broad spectrum antibiotics.
3. For patients who were admitted to the ICU (P = 0.26)
a. Definite 16.5%
b. Likely 8.6%
c. Unlikely 16.4%
d. Definitely no 20.4%
4. Source of infection
Approximately 30% of patients who had blood cultures drawn and received broad spectrum antibiotics in ED have low likelihood of bacterial infection.
