Purpose: To determine the degree of concordance between thrombolytic checklists completed by emergency medical technicians (EMTs) in the field and corresponding checklists completed by emergency physicians in the emergency department (ED).

Methods: This was a comparative analysis of matched pairs of thrombolytic checklists. Subjects included patients 35 years or older with clinical signs or symptoms of cardiac origin who were transported to the ED by ambulance. The checklist contained 12 items and was completed by EMTs during transport of eligible patients. An identical checklist was completed in the ED by an emergency physician upon arrival of the patient. The main outcome measurement was concordance between the matched pairs.
