Objectives: This study was used to test the effect on planned safe use of over-the-counter (OTC) analgesics of adding information about the potential for nonsteroidal anti-inflammatory drug (NSAID) interaction with antihypertensive medications, the potential for interaction of alcohol and acetaminophen, and NSAID ceiling effects to the Federal Drug Administration's (FDA's) OTC analgesics pamphlet.
Design: A randomized posttest-only double-blind experimental design was used to test an intervention with a comparison group reading the FDA pamphlet, and treatment group reading the pamphlet with added information.
Sample: Participants included 137 adults.
Percutaneous coronary intervention for patients with ST-segment elevation myocardial infarction (STEMI) decreases morbidity and mortality if performed within the first 2 hours of symptom onset. However, the American College of Cardiology/American Heart Association guideline for percutaneous coronary intervention door-to-balloon time (<90 minutes) in patients with STEMI is a infrequently accomplished goal. This study enrolled 277 patients with STEMI who were self-transported or transported by emergency medical services to NorthEast Medical Center for primary percutaneous coronary intervention.

Further delays in the time to treatment typically lead to reduced benefits and poorer outcomes.
Methods: Cabarrus County Emergency Medical Service personnel complete an acute myocardial infarction case report form and assess a 12-lead electrocardiogram (ECG) to determine if ST elevation of at least 1 mV in at least 2 contiguous leads is present and then to transmit the ECG wirelessly to the emergency department (ED).
