A Nationwide Study of Emergency Nurses' Triage Decisions for Potential Acute Coronary Syndrome.

Introduction: This study aimed to identify the symptoms used to assess angina, determine how emergency nurses make triage decisions for potential acute coronary syndrome, and determine emergency nurses' initial actions.

Methods: This was a cross-sectional, survey-based design. Emergency nurses were recruited through a posting on the Emergency Nurses Association website and through postcards. Measures included demographic data, assessment of angina, and the Nurses' Cardiac Triage Instrument. Data were analyzed using descriptive statistics and ordinal logistic regression.

Results: A total of 414 registered nurses with a mean age of 41.7 (SD = 12.0) years participated. They were predominantly female (80.7%), had a baccalaureate degree (60.1%), and worked as a registered nurse for a median 10.0 years. Common terms used to assess angina were chest pain (79.5%), chest pressure (77.3%), chest tightness (72.9%), and chest discomfort (72.5%). The severity of chest pressure (median 5.0, interquartile range 1.0) and nature of chest pain (median 5.0, interquartile range 1.0) had the highest overall median scores to support initial cardiac triage decisions. Associated symptoms of diaphoresis, fatigue, and shortness of breath along with health history contributed to decision making.

Discussion: Emergency nurses primarily used chest symptoms and health history when deciding to evaluate for acute coronary syndrome in the emergency department. Associated symptoms of diaphoresis, fatigue, and shortness of breath, along with health history, also contributed to decision making. Initial registered nurse actions were to obtain an electrocardiogram, prepare the patient for the cardiac catheterization laboratory, and notify the emergency physician of the patient's admission.
