Open or close this module Study Description
Brief Summary: The aim of this study is to evaluate the validity and the reproducibility of the canadian triage and acuity scale when applied by regular nurses for the triage of children in the Emergency Department.
Detailed Description: The role of triage in the Emergency Department (ED) is to assign high priority to patients who need urgent care while identifying patients that may be able to wait safely. The Canadian Triage and Acuity Scale (CTAS) is a triage tool constructed from a consensus of experts that is universally used in Canada. Until now, there has been no evaluation of the validity of the tool for children in a clinical context. Also, its inter-rater reproducibility has not been evaluated. The expected implementation of a revised version of the Canadian triage tool in 2008 would be an ideal moment to evaluate its validity and reproducibility. Specific objective: 1. To evaluate the validity of the CTAS for children visiting a pediatric ED and 2. To measure the inter-rater agreement for nurses using the CTAS in these settings.

Primary Outcome Measures:
1. The inter-rater agreement between the two nurses measured by the weighted Kappa score
[ Time Frame: 15 minutes ]

2. The correlation between triage level and the hospitalisation rate
[ Time Frame: 1 day ]

Secondary Outcome Measures:
1. The correlation between triage level and admission to the intensive care unit
[ Time Frame: 1 day ]

2. The correlation between triage level and length of stay in the ED after being seen by a physician
[ Time Frame: 1 day ]

3. The correlation between triage level and resources use
[ Time Frame: 1 day ]
