Mitigating clinical waste in the trauma intensive care unit: Limited clinical utility of cardiac troponin testing for trauma patients with atrial fibrillation.

Background: The clinical significance of obtaining cardiac troponin (cTn) levels among trauma patients with new onset arrhythmias is unknown. We aimed to assess whether cTn levels actually influence clinical decision making or represent an inappropriate use of resources.

Methods: Trauma patients admitted from 2013 to 2014 diagnosed with atrial fibrillation (AF) were retrospectively reviewed using the institutional trauma database.
