The Electronic Canadian Triage and Acuity Scale (E-CTAS) is a popular system that categorizes patients into five levels to manage patient flow and prioritize patient access to health-care services.


 We assessed the factors that influence E-CTAS usage in emergency departments in Eastern Saudi Arabia.  Seventy-one nurses were included from two emergency departments that adopted E-CTAS.  All of the TAM domains were significantly related to the usage of E-CTAS: perceived ease of use, perceived usefulness, importance of training, social influence, behavior intention, and attitude.  We also showed that E-CTAS use significantly increased with years of experience and training.

We used the technology acceptance model (TAM) to assess the influencing factors.  The TAM was reliable in the study setting (Cronbach's α = 0.87).
