Canadian Emergency Department Diagnosis Shortlist (CED-DxS)

The Canadian Emergency Department Diagnosis Shortlist (CED-DxS) enables national, standardized, reliable administrative reporting of Emergency Department (ED) diagnoses in Canada. The CED-DxS is a 'Health System Use' (HSU) standard. The list is a subset of the International Statistical Classification of Diseases and Health Related Problems, 10th Revision, Canada (ICD-10-CA) and contains 841 diagnosis codes, code descriptions and associated common terms.

Common terms are selected from a pick list by clinicians and mapped to ICD-10-CA. Common terms and ICD-10-CA code titles are provided in English and French in the CED-DxS.

Business Functions

The CED-DxS is designed to be used by emergency department clinical staff (physician or nurse) at the time of service. The list is best used in an emergency department information system (EDIS) but may be used in other systems such as a hospital admission-discharge-transfer (ADT) and/or abstracting system to facilitate collection of discharge diagnosis information.

The pick list allows structured input to be received and variation in data collection to be minimized. This facilitates comparative reporting to identify patient populations, workloads, staffing and resource needs. This information can also be used for clinical quality improvement, research and benchmarking at local, regional and national levels.

Supporting Organization

Established in 1994, the Canadian Institute for Health Information (CIHI) is an independent, not-for-profit corporation that provides essential information on Canada’s health system and the health of Canadians.

The CED-DxS can be ordered from the CIHI website. Learn more.


* Status Definitions

Canadian Draft for Use (CDFU) - The standard has been developed but it may or may not be implemented or be in use. The standard is considered ready to be used by early adopters: however, change is probable as stakeholders begin using the standard in implementations.

Canadian Approved Standards (CAS) - The standard is in use for the purpose(s) or context(s) for which it was intended. Only those parts of the standard that have been implemented or are in use can progress for consideration as CAS. This decision point signifies that the standard has reached a level of stability and is comprehensive enough such that major changes are not expected.
