208. Early Infectious Disease Consultation is Associated with Lower Mortality in Patients with Severe Sepsis or Septic Shock who Complete the 3-hour Sepsis Bundle

Abstract

BackgroundSevere sepsis and septic shock bundles have been shown to reduce mortality. Infectious Diseases (ID) consultation, particularly early in a hospital course, is associated with improved patient outcomes. Antibiotic Stewardship Program (ASP) decision support in the ED has also shown clinical benefit. We aim to examine the addition of early ID consultation to existing ASP decision support in the Emergency Department (ED) in patients with sepsis with organ dysfunction and/or shock (SODS) who completed the 3-hour bundle.MethodsThis is a retrospective study of 248 adult patients with clinical SODS who met inclusion criteria per Center for Medicare and Medicaid Services SEP-1 core measure in the ED and completed the recommended 3-hour sepsis bundle using ASP decision support tools. Patients who received ID consultation in the first 12 hours after ED triage (n = 111) were compared with patients who received standard care (n = 137). Pearson’s chi-square test was used to compare groups for all-cause 30-day readmissions and in-hospital mortality. Logistic regression was used to adjust for covariates (age, race/ethnicity, Charlson score, lactate level ≥4, hypotension, recent hospital admission, recent IV antibiotics, history of MDR organisms, intra-abdominal source of infection). Time from ED triage to death and time to hospital discharge alive were analyzed using Fine and Gray models for competing risks.ResultsIn-hospital mortality was lower among patients who received early ID consultation (24.3% vs. 38.0%, P = 0.0220). This association persisted after adjustment for covariates (odds ratio 0.49, 95% CI 0.26–0.91, P = 0.0236). There was no significant difference in 30-day readmissions between groups (22.6% vs. 23.5%, P = 0.8883). Early ID consultation was predictive of time to death (adjusted hazard ratio 0.58, 95% CI 0.35–0.98, P = 0.0406) and time to hospital discharge alive (adjusted hazard ratio 1.51, 95% CI 1.07–2.12, P-value 0.0174) after adjustment.ConclusionEarly ID consultation was associated with lower mortality and time to hospital discharge among patients receiving the 3-hour severe sepsis/septic shock bundle. Further investigation is needed to explore specific interventions by ID consultants that might reduce the risk of mortality in this population. Disclosures All authors: No reported disclosures.
