Background. To differentiate acute coronary syndrome (ACS) from other causes in patients presenting with chest pain at the\nemergency department (ED) is crucial and can be performed by the nurse triage. We evaluated the effectiveness of the ED nurse\ntriage for ACS of the tertiary care hospital. Methods.We retrospectively enrolled consecutive patients who were identified as ACS\nat risk patients by the ED nurse triage. Patients were categorized as ACS and non-ACS group by the final diagnosis. Multivariate\nlogistic analysis was used to predict factors associated with ACS. An online model predictive of ACS for the ED nurse triage was\nconstructed. Results.There were 175 patients who met the study criteria. Of those, 28 patients (16.0%) were diagnosed with ACS.\nPatients with diabetes, patients with previous history of CAD, and those who had at least one character of ACS chest pain were\nindependently associated with having ACS by multivariate logistic regression. The adjusted odds ratios (95% confidence interval)\nwere 4.220 (1.445, 12.327), 3.333 (1.040, 10.684), and 12.539 (3.876, 40.567), respectively. Conclusions. The effectiveness of the ED\nnurse triage for ACS was 16%. The online tool is available for the ED triage nurse to evaluate risk of ACS in individuals.
