The Countess of Mar tabled a question asking the Government how many NHS chronic fatigue syndrome service centres are fully functional; what percentage of patients referred with ME/CFS are subsequently found to have fatigue associated with other chronic conditions; and what measures are in place to ensure that patients with chronic fatigue are effectively screened for other relatively rare diseases before they are given a diagnosis of ME/CFS.
In a written answer supplied on 10 February 2011, Parliamentary Under Secretary for Health Earl Howe replied:
Information on the number of fully functioning National Health Service *chronic fatigue* services centres is not collected centrally.
The department does not collect the requested information on those people attending *chronic fatigue syndrome* centres.
The guidelines published by the National Institute for Health and Clinical Excellence states that a positive diagnosis of *chronic fatigue syndrome/myalgic encephalomyelitis* should be made after other known causes for the symptoms have been excluded.
