Aim The purpose of this study was to better understand the effects of introducing the Japan Triage and Acuity Scale ( JTAS ) in the emergency room for walk‐in patients. Methods A simple triage was used in Term A (from April 2006 to December 2010, 4 years and 9 months) and the JTAS was introduced in Term B (from January 2011 to September 2015, 4 years and 9 months). The number of patients who had a sudden turn for the worse after arrival in the emergency room and the time between attendance and emergency catheterization ( TBAEC ) due to acute coronary syndrome were reviewed. Results There were 653 patients in Term A and 626 patients in Term B who were finally diagnosed as having serious causes. There was no significant difference in the frequency of a sudden turn for the worse between the two terms. There were 182 patients in Term A and 167 patients in Term B who underwent emergency catheterization due to acute coronary syndrome. When ST elevation was recognized in the first electrocardiogram, the median time between attendance and medical attention during Term B improved significantly, by 4.5 min. However, there was no significant difference in medians for TBAEC . When ST elevation was not recognized, there was no significant difference between the two terms, neither in terms of median time between attendance and medical attention, nor TBAEC . Conclusion The data suggests that the effects of introducing the JTAS in the emergency room were restrictive in these two aspects.
