Shock index (heart rate/systolic blood pressure) has been used to predict trauma outcomes. This study from American Journal of Emergency Medicine looked at 89,000 pre-hospital patients who had a normal shock index on arrival at an emergency department. They then looked for those with abnormal pre-hospital shock index vs. those without an abnormal shock index and compared outcomes. Those with an abnormal pre-hospital shock index had worse outcomes than those with normal pre-hospital shock index.
Bottom line: A good handoff from pre-hospital to emergency department staff is critical because any abnormal shock index predicts a worse outcome than those with a normal shock index.
