SEPSIS Projects

Evaluation and Comparison of Sepsis Definitions (PIs: Chanu Rhee, MD, MPH; Michael Klompas, MD, MPH

The aims of this multicenter project (conducted in collaboration with University of Washington in St. Louis and Duke University) were to: 1) Evaluate and compare the clinical characteristics, associated morbidity and mortality, and overlap of the Sepsis-3 clinical definition with the proposed Epicenters’ EHR-based sepsis surveillance definition and sepsis administrative claims definitions, 2) Determine the attributable mortality of hospital-onset sepsis and identify the associated clinical characteristics and comorbidities of patients who die from sepsis, and 3) Quantify interobserver variability in assessing compliance with the CMS sepsis measure.

Sepsis Time Zero

A major barrier to providing appropriate sepsis care is our limited understanding of which specific clinical presentations are most likely to benefit from immediate antibiotics and fluids and which can safely be managed more conservatively. Additionally, we have an imperfect understanding of which care processes are critical to optimizing patient outcomes. To address these gaps, we are researching better ways to define sepsis “time zero,” a concept that embodies both the criteria that should trigger immediate interventions when infection is suspected and the point from which timeliness of care is measured. In this project, we are leveraging detailed EHR data from millions of encounters across 167 hospitals in two datasets  in support of the following aims: 1) Develop evidence-based, objective, and electronically computable definitions of sepsis time zero by using electronic health record data to identify the clinical signs that are associated with higher mortality when antibiotics are delayed, 2) Systematically evaluate the associations between each sepsis bundle component and mortality and compare the full bundle to simpler, streamlined versions, and 3) Assess whether and how optimal treatment strategies differ for commonly encountered and easily recognizable sepsis phenotypes based on infection site, comorbidities, and clinical signs.
