Chronic Multisymptom Illness S025
Current RMA Instruments:
|Reasonable Hypothesis SOP||55 of 2014|
|Balance of Probabilities SOP||56 of 2014|
Chronic multisymptom illness is not a disease in a conventional sense.
This SOP has been created by the RMA to cover: particular groupings of symptoms; that result in distress and severe disruption of functioning; and that are not better explained by another medical or psychiatric condition. The symptom sets potentially covered by this condition come from the following list:- fatigue, feeling depressed, difficulty remembering or concentrating, feeling moody, feeling anxious, trouble finding words, difficulty sleeping, joint pain, joint stiffness and muscle pain. See the SOP definition for further details. The presence of another condition that would account for the symptoms precludes a diagnosis of chronic multisymptom illness. Similar symptom sets may occur in psychiatric disorders, brain pathology, terminal cancers, immunodeficiency disorders, cardiac disease, respiratory disease, blood disease, rheumatological disorders and chronic fatigue syndrome.
Is specific diagnostic evidence required to apply the SOP? – Yes.
This diagnosis is complex and is a diagnosis of exclusion. A business line is available that details the steps that should be taken to investigate claims.
Are there sub-factors that require specific information? – No.
Additional diagnoses that may be covered by SOP
Gulf war syndrome – gulf war syndrome is not a disease or injury for the purposes of the VEA (or MRCA). A claim for gulf war syndrome should be rejected on that basis, but such a claim should also be investigated to see if there is any other diagnosis that may be made. In that situation a diagnosis of chronic multisymptom illness may warrant investigation.
