Comparison of Triage Models of Suspected ACS Patients: A Case Study of the Far Eastern Memorial Hospital
This study aimed at evaluating four existing models, comprising he Zarich’s model , the flowchart model [2, 3], and the Heart Broken Index (HBI) model , for triaging potential acute coronary syndrome (ACS) patients who presented at the emergency department. The 793 clinical cases, randomly selected from 7,962 clinical cases that applied the HBI in the ED of the Far Eastern Memorial Hospital in Taiwan, were used for the model testing. The results showed that although the chest-pain and HBI models had high sensitivity (both 99.24%), they had very low specificity (3.93% and 4.08%), whereas the Zarch’s and flowchart models had relatively higher specificity (14.98% and 17.25%), but they had lower sensitivity (96.97% and 93.18%). To increase specificity and maintain high sensitivity while triaging suspected ACS patients, future research can focus on using systematic methods to develop more effective ACS triage models.
