The Canadian Triage & Acuity Scale (CTAS) is a tool that enables Emergency Departments (ED) to:
- Prioritize patient care requirements
- Examine patient care processes, workload, and resource requirements relative to case mix and community needs
The CTAS allows ED nurses and physicians to:
- Triage patients according the type and severity of their presenting signs and symptoms
- Ensure that the sickest patients are seen first when ED capacity has been exceeded due to visit rates or reduced access to other services
- Ensure that a patient's need for care is reassessed while in the ED
The CTAS allows ED managers to:
- Measure the case mix (volume and acuity) of patients who visit the ED
- Determine whether the ED has an operational plan and the resources to meet patient needs
- Assess the ED's role within the hospital and health care region
The triage level assigned using the CTAS criteria is a mandatory data element to be used in all Canadian Hospital Emergency Departments for reporting to the Canadian Institute for Health Information.

- CTAS 2nd Order Modifiers
- Paediatric CTAS 1st Order Modifiers
- Desktop Reference
- The CTAS Desktop reference is a 45 page coil bound, water resistant book, sized to fit a lab coat pocket, which contains the CEDIS complaint list, Adult and Paediatric first order modifiers and their definitions, as well as the key special consideration complaints and relevant second order modifiers. This offers a quick and comprehensive reference for nurses not having access to computer decision support. Posters are 36 inches wide by 24 inches long.

2008 Revised Paediatric CTAS Implementation Guidelines
Since the original Paeds CTAS Implementation guidelines published in 2001 a standardized CEDIS complaint list was published. A revised CEDIS version in 2008 was published to be more inclusive of the diversity of adult and paediatric presentations and the paediatric complaints were included in the system based list rather than separated. The new implementation guideline clarifies the similarity of the process for adult and paediatric triage while recognizing some of the unique aspects of children's presentations. The revised guidelines will be incorporated into the new CTAS NWG teaching package and will make it easier to incorporate in a single education format and to implement in emergency department electronic information systems.

2008 Revised Adult CTAS Implementation Guidelines
In conjunction with the 2008 CEDIS presenting complaint list revisions, the Adult CTAS guidelines have also been revised based on research and stakeholder feedback. To understand the current content and implementation of adult CTAS readers need to include the 2004 guideline revisions as the 2008 manuscript only identifies modifications to the 2004 paper, but does not repeat any of the content that is unchanged. This updated material will be included in the CTAS updated educational package by summer 2008. The supplement (see below under support documents) has also been revised to maintain the link between the CEDIS complaints and the standardized 1st and 2nd order CTAS modifiers in a format supportive of computerization.

2004 Revised Adult CTAS Implementation Guidelines
Following the publication of the CEDIS presenting complaint list in 2003, experimentation with CTAS electronic decision support, and results of CTAS research the adult guidelines were revised to combine the complaints and standardized CTAS modifiers in a format compatible with computerization.

2001 Paediatric Implementation Guidelines
Recognizing the special challenges the assessment of children posed CAEP, NENA, and AMUQ combined with the Canadian Paediatric Society to develop the first Paeditric specific guidelines.

2013 Content Standards linking CEDIS Complaints to related CTAS Modifiers
Excel spreadsheets (Adult and Paediatric) organized into the 17 CEDIS Presenting Complaint categories with individual Complaints listed in alphabetical order by group. The relevant 1st and 2nd order modifiers are provided for each complaint along with the relevant score, codes, and action notes. The 1st order modifiers are defined along with the majority of terms. In addition there is a rule reference key and an abbreviations key. The goal of these documents is to assist programmers wishing to create CTAS clinical decision support within their EDIS product. The pdf document instructs the reader how to use the excel spreadsheets.

CTAS Complaint Oriented Triage (COT) teaching/reference tool
This Microsoft Powerpoint file transforms the updated Adult and Paediatric CTAS and the CEDIS chief complaints into a single tool that allow users to better understand how to operationalize the revised CTAS. As a user, just choose the complaint category, select the complaint, and then review the relevant modifiers to assign the appropriate triage score. This can be used as an adjunct to teach CTAS or as a user friendly tool in triages that lack informatic resources. The Adult COT has a red background while the Paediatric COT has blue background. This was done in order to avoid confusion between the triage modifiers.
To use the slides properly, view in "slide mode" or Shift+F5. Many of the squares have underlying hyperlinks. MAC users see below.
There will be 4 versions, English Canada and French Canada versions using the numeric coding based on the National Ambulatory Care Reporting System (NACRS) plus English Quebec and French Quebec versions using the Ministère de la Santé et des Services sociaux (MSSS) numeric codes. Below you will find the links for the English Canada version and the Quebec French version. The other versions will be completed soon.
If you use PowerPoint and receive many presentations from coworkers who use PowerPoint on PCs, you're probably familiar with the (sometimes agonizingly slow) process of "graphic metafile conversion." This is something that PowerPoint on the Mac must do to allow you to view and use any graphics embedded by PC users. The problem is that if you do the natural thing -- open the presentation and start looking through it slide by slide -- this conversion process happens every time you advance to the next slide.
Here are a couple of handy timesavers to spare yourself the annoyance of waiting for the conversion on every slide. Note that these won't make the process any shorter (the conversion still has to take place), but they will make it much less annoying.
***The first, and simplest, thing to do is to just save the presentation. When you save it, PowerPoint will convert all the graphic metafile at once, during the save operation. Opening the newly-saved presentation will allow you to breeze through all the slides, as the conversion has been done.***
The second option is to switch to the slide sorter view (View -> Slide Sorter), which also forces an all-at-once conversion of the graphics metafiles.
The third method is to hit File -> Print after opening the presentation. Again, the metafile data will all be converted, and you can cancel out of the Print dialog box when it's done.
If you use the second two options, remember to save the presentation when you're done, so you won't have to wait through the conversion again.
Non urgent patient implications
This article concludes that while non urgent patients are not a strain on ED resources as they often don’t require stretchers, it would be unsafe to use triage score to divert patients away as there was a 7.6% admission rate among these patients.
The CTAS has been approved by the following organizations:
