Factors Affecting the Time to First Dose Antibiotic in Sepsis in Acute Emergency

BACKGROUND: The Surviving Sepsis Campaign recommends the administration of antibiotics within 1 hour of triage time in sepsis patients. The purpose of this study was to determine the factors affecting the time to first dose antibiotics in sepsis patients presenting to the emergency department (ED). METHODS: We conducted a prospective observational study on factors affecting the time to first dose antibiotics in patients with sepsis presenting to the ED over a period of 7 months (July 2019 to January 2020). The purpose of this study was to determine the factors affecting the time to first dose antibiotics in sepsis patients. RESULTS: During the study period, a total of 410 patients with a mean age of 51.6 years were presented to the ED with sepsis. Majority was triaged to priority 1 (84.8%). The median door to antibiotic time was 50 minutes (IQR, 40–90). Two-thirds (68%) of the patients (279) received antibiotics within 60 minutes. The blood culture positivity rate was 22.9%, and the contamination rate was 6%. The most common factors for the delay were atypical presentation (36.6%) and unknown focus of infection (36.6%). Triage to non-acute areas of the ED (priority 2) was associated with delayed antibiotic administration [odds ratio (OR), 7.3; 95% confidence interval (CI), 4.03–13.36; p-value <0.001]. Patients presented with cellulitis and necrotizing soft tissue infection (NSTI) had received antibiotics within an hour compared to other diagnoses (18.3 vs 8.4%; OR, 2.4; 95% CI, 1.2–4.9; p = 0.009). CONCLUSION: Two-thirds of our patients received their first dose of antibiotics within an hour of presentation to the ED. Triage to lower priorities was an independent risk factor for delay in first-dose antibiotic administration, and patients presented with an obvious focus of infections like cellulitis and NSTI received their first dose of antibiotic much earlier when compared to other diagnoses.
