Early intervention by EMS personnel in acute cardiovascular disease improves outcomes in cardiac arrest, stroke, and ST elevation myocardial infarction. However, the definition, risk stratification, and treatments for field shock are unclear. This project seeks to develop classification models by shock etiology for high risk emergency patients, and test the effectiveness of field resuscitation on patient outcomes. We hypothesize that the benefit for early fluid resuscitation may be most compelling for non-cardiovascular shock, while potentially harmful for those with acute cardiovascular compromise. We will use advanced comparative effectiveness estimators to determine treatment effects across shock etiology.
