- Having possible palliative care needs. Referrers were encouraged to identify people as severely affected with MS based on their clinical need, rather than relying on any standardised measures of disability. However, since a large Canadian population study identified that approximately 15% of people with MS have an Expanded Disability Scale Score of 8 or more (out of a possible 10)23, this was also suggested to referrers as a benchmark for disability that would prompt consideration of referral. Examples of palliative care needs were given as unresolved symptoms, psychosocial concerns, and end of life issues, progressive illness or complex needs.
