Retrospective evaluation of resuscitation medication utilization in hospitalized adult patients with cardiac arrest.

Background: Early medication administration in cardiac arrest improves outcomes. The primary objective was to evaluate the association between epinephrine administration in in-hospital cardiac arrest (IHCA) patients with non-shockable rhythm and the patient outcomes. The secondary objective was to assess the compliance of epinephrine and amiodarone administration in accordance with the advanced cardiovascular life support (ACLS) guideline.
