Temporal and Provincial Variation in Ambulance Use Among Patients Who Present to Acute Care Hospitals With ST-Elevation Myocardial Infarction

摘要

Background: At the first sign or symptoms consistent with an ST-elevation myocardial infarction (STEMI), patients are encouraged to call 9-1-1 and activate emergency medical services immediately. We examined: (1) temporal trends and provincial variations in the proportion of STEMI patients who arrive by ambulance; and (2) the association between patient demographic and clinical characteristics and ambulance use.
