Implementation of an EMS protocol to improve prehospital sepsis recognition.

ABSTRACT

PURPOSE: Optimal sepsis outcomes are achieved when sepsis is recognized early. Recognizing sepsis in the prehospital, EMS setting can be challenging and unreliable. The purpose of this study is to evaluate whether implementation of an EMS sepsis screening and prehospital alert protocol called PRESS (PREhospital SepsiS) is associated with improved sepsis recognition by EMS providers. DESIGN: We conducted a 12-month, before-after implementation study of the PRESS protocol in a large, public EMS system. The study intervention was a PRESS training program delivered to EMS providers. EMS patient inclusion criteria included age ≥ 18 years, EMS systolic blood pressure < 110 mmHg, EMS heart rate > 90 bpm, and EMS respiratory rate > 20 bpm. Study exclusion criteria included the presence of any of following EMS conditions trauma, cardiac arrest, pregnancy, toxic ingestion, or psychiatric emergency. Retrospective chart review was performed on all eligible EMS encounters during the study period. The primary outcome variable was the proportion of patients with sepsis who were identified by EMS providers. RESULTS: Approximately 300 EMS providers were trained to use PRESS. A total of 498 patient encounters met criteria for study inclusion; 222 were excluded, primarily due to trauma. A total of 276 patient encounters were analyzed. Sepsis recognition by EMS providers increased from 12% pre-PRESS protocol to 59% post-PRESS protocol (p < 0.001). In a post-hoc analysis of the post-PRESS cohort, septic patients who were identified by EMS received antibiotics 24 min faster than septic patients who were not identified by EMS [28 min (IQR 18-48) vs 52 (IQR 27-98), respectively, p = 0.021]. CONCLUSION: Implementation of an EMS sepsis screening and prehospital alert protocol was associated with an increase in sepsis recognition rates by EMS providers and a decrease in time to first antibiotic administration in the emergency department. Further studies are needed to evaluate the impact of this protocol in other populations.
