By using the official application, nurses and physicians can be assured that they are using the most current and accurate scale as developed and revised by the National Working Group. Triage accurately! It helps patients receive the care and measures your acuity and volume against other facilities with reliability. The CTAS is used in many countries around the world for setting patient priority. 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 (CIHI). Training in the use of the CTAS in the clinical context is recommended before using this application to assist in clinical decision-making.
