Purpose: The purpose of this study was to determine whether, in patients with acute coronary syndrome (ACS), according to the mode of arrival affect the emergency medical process.
Methods: The participants of this study were 118 adult patients (46 patients admitted by emergency medical services (EMS), 48 walk-in patients, and 24 transferred from other hospitals) admitted to the emergency departments at one regional-level medical center who underwent coronary angiography between January 1, 2016 and December 31, 2017. To compare treatment courses, the median values of the following variables were compared among groups: symptom to door time; door to triage time; and door to ECG time. All data were analyzed using SPSS program.
Results: Based on the initial assessment at triage, there was a significantly greater proportion of Korean Triage and Acuity Stage (KTAS) Level 1 or 2 among patients admitted by EMS than among walk-in patients. All three analyzed variables were lower in patients admitted by EMS than in the other two groups.
Conclusion: Our results show that ACS patients who accessed EMS reached the emergency center faster after symptom onset, received initial triage assessment at earlier stages, and underwent sooner important examinations (i.e., the 12-lead ECG).
