Reliability of the Swiss Emergency Triage Scale (SETS®) Used by Emergency Medical Service (EMS) Providers

Study Overview
=================
Brief Summary
-----------------
The Swiss Emergency Triage Scale (SETS) in used for triage in emergency departments in Switzerland, France and Belgium. No validated triage scale is actually used by Emergency Medical Service (EMS) providers. The objective of this project is to evaluate the reliability and performance of triage by EMS providers with the SETS.

Detailed Description
-----------------
The Swiss Emergency Triage Scale (SETS) in used for triage in emergency departments in Switzerland, France and Belgium. No validated triage scale is actually used by EMS providers. The objective of this project is to evaluate the reliability and performance of triage by EMS providers with the SETS. In order to perform this evaluation a cohort of 22 EMS providers will evaluate 28 standardized clinical scenarios using a computer simulator.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Emergency level (1 to 4) accordingly to the SETS | Each participant will attribute an emergency level (1 to 4) to all clinical vignettes accordingly to SETS criteria. Reliability will be evaluated by computing inter-rater reliability using Kappa statistics. | 1 day: all computeriez vignettes will be evaluated during a one-day session in November 2015. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Correct emergency triage level identification | Triage levels attributed by EMS providers will be compared with triage levels attributed by experts | 1 day: all computeriez vignettes will be evaluated during a one-day session in November 2015. | 
| Proper orientation | At the end of triage process, EMS providers have to decide in which hospitals the patients should be admitted. These orientations given by EMS providers will be compared with orientations attributed by experts | 1 day: all computeriez vignettes will be evaluated during a one-day session in November 2015. |
