Abstract
BACKGROUND The National Institute for Emergency Medicine uses the Emergency Severity Index (ESI) to classify the condition of patients who come the emergency room. The ESI has 5 levels of triage, but it requires a lot of experience on the human side to use this system. An alternate way to triage patients is the Canadian Triage and Acuity System (CTAS) that is completely computer based. In this study we want to compare ESI and CTAS in regards to accuracy of emergency triage system in an emergency room in Chiangrai Prachanukroh Hospital.
Objective: To study the accuracy of patient triage systems in patients presenting to the Emergency Department of Chiangrai Prachanukroh Hospital by comparing Emergency Severity Index (ESI) to Canadian Triage and Acuity Scale (CTAS).
Methods: This study is a descriptive cross-sectional study. Patients presenting to the Emergency Department of Chiangrai Prachanukroh Hospital from August to December 2018 in the hours 08:00am -04.00 pm., were enrolled. A total of 406 patients was included in the study.
RESULTS When comparing ESI to CTAS, ESI was found to have a high correlation to those of CTAS, rs = 0.7965 (p-value = 0.0000). ESI level I was found to have the highest correlation, rs = 0.8250 (p-value = 0.0000) and ESI level III was found to have the lowest correlation, rs = 0.0006 (p-value 0.9912).
CONCLUSIONS AND DISCUSSIONS Triage levels designated by the ESI triage scheme had a significant correlation to that of CTAS. Thus, ESI is another efficient and effective 5-level triage tool.
