Title: Abnormal pre-hospital SI is a poor predictor even with a normal arrival SI<br/>Author: Robert Flint<br/><a href='http://umem.org/profiles/faculty/2561/'>[Click to email author]</a><hr/><p>
Shock index (heart rate/systolic blood pressure) has been used to predict trauma outcomes. This study from <em>American Journal of Emergency Medicine</em> 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.</p>
<p>
<strong>Bottom line</strong>: 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.</p>
