Drug Standard

Drug Standards provide physicians, pharmacists and other health care providers with an improved ability to manage complete patient medication profiles across the continuum of care through a jurisdictional Drug Information System.

* 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.
