The Effect of Competency-Based Triage Education Application on Emergency Nurses' Triage Competency and Performance.

The Korean Triage and Acuity Scale (KTAS) is used to determine emergency patient priority. The purpose of this study was to develop the Competency-Based Triage Education Application (CTEA) using KTAS and evaluate its effectiveness on emergency nurses' triage competency and performance. The developed CTEA mobile application comprised 4 lectures, 12 text-based cases, and 8 video-based triage scenarios. A quasi-experimental pre-post design with a comparison group (CG) was used to evaluate the effectiveness of the CTEA. Thirty-one participants were assigned to an intervention group (IG) and used the application for at least 100 min over one week. Thirty-five participants were assigned to a CG and underwent book-based learning, which covered the same content as the CTEA. Triage competency (t = 2.55, = 0.013) and performance (t = 2.11, = 0.039) were significantly improved in the IG. The IG's undertriage error was significantly reduced compared to that of the CG (t = 2.08, = 0.041). These results indicated that the CTEA was effective in improving the emergency nurses' triage competency and performance. This application will be useful as a program for providing repeated and continuous triage education.
