The National ME/FM Action Network of Canada spearheaded the drive for the development of an expert consensus document for Myalgic Encephalomyelitis / Chronic Fatigue Syndrome (ME/CFS). In response to increasing numbers of patients inquiring about doctors knowledgeable about ME/CFS, the Network sent a questionnaire to doctors across Canada asking what items would be most helpful in assisting them with their ME/CFS patients. The physicians concurred that a clinical definition, as well as diagnostic and treatment protocols were of prime importance.
Here is the full version Canadian Consensus Document (CCD) (2003) . An overview of the full document was developed in 2005: Overview, Canadian ME:CFS Clinical Case Definition and Guidelines for Medical Practitioners (2005).
