Abstract

Background: Severe sepsis is a condition with a high mortality rate, and the majority of patients are first seen by Emergency Medical Services (EMS) personnel.

Objective: This research sought to determine the feasibility of EMS providers recognizing a severe sepsis patient, thereby resulting in better patient outcomes if standard EMS treatments for medical shock were initiated.

Methods: We developed the Sepsis Alert Protocol that incorporates a screening tool using point-of-care venous lactate meters. If severe sepsis was identified by EMS personnel, standard medical shock therapy was initiated. A prospective cohort study was conducted for 1 year to determine if those trained EMS providers were able to identify 112 severe sepsis patients before arrival at the Emergency Department. Outcomes of the sample of severe sepsis patients were examined with a retrospective case control study.

Results: Trained EMS providers transported 67 severe sepsis patients. They identified 32 of the 67 severe sepsis patients correctly (47.8%). Overall mortality for the sample of 112 severe sepsis patients transported by EMS was 26.7%. Mortality for the sample of severe sepsis patients for whom the Sepsis Alert Protocol was initiated was 13.6% (5 of 37), crude odds ratio for survival until discharge was 3.19 (95% CI 1.14-8.88; p = 0.040).

Conclusions: This pilot study is the first to utilize EMS providers and venous lactate meters to identify patients in severe sepsis. Further research is needed to validate the Sepsis Alert Protocol and the potential associated decrease in mortality.
