Given the implementation of the Hamilton Early Warning Score (HEWS) and the use of capnography by paramedics, this study will involve a large multi-site retrospective evaluation (before vs after implementation) of the HEWS score and comparison of the HEWS to systemic inflammatory response syndrome (SIRS), quick Sepsis Related Organ failure Assessment (qSOFA) and Modified Early Warning Score (MEWS) when applied retrospectively for the identification of sepsis in the prehospital setting.
1. To determine the accuracy of the HEWS score, compared to qSOFA, and SIRS for early sepsis recognition when used in the prehospital setting by paramedics for the identification of patients with sepsis or suspected sepsis. 2. To evaluate the addition of ETCO2 values to predict mortality in patients who screen positive for sepsis. 3. To identify the before and after healthcare outcomes of a prehospital sepsis alert program.
