Factors associated with severity of accidental hypothermia: A cohort retrospective multi-institutional study.BACKGROUND
 Frequently it is difficult to determine illness severity in hypothermic patients.  Our goal was to determine if there are factors associated with illness severity of hypothermic emergency department (ED) patients.


 Hypothermic patients (≤35 °C) were identified using ICD codes.  There were 2094 visits with hypothermia ICD code.  For hypothermic ED patients increased severity of illness was associated with older age and found indoors but not associated with initial temperature, gender, alcohol or trauma.
