Our design followed the MRC Framework for the Evaluation of Complex Interventions. The investigators modelled a new palliative care and neurology service for patients affected by Multiple Sclerosis (MS) by conducting qualitative interviews with patients, families and staff, plus a literature review to model and pilot the service. Then the investigators started to offer the service and designed a delayed intervention randomised controlled trial to test its effectiveness as part of phase II of the MRC framework. Inclusion criteria for the trial were patients identified by referring clinicians as having unresolved symptoms or psychological concerns. A disability of scoring greater than 8 on the Expanded Disability Scale was identified as a benchmark. Consenting patients newly referred to the new service were randomised to either receive the palliative care service immediately (fast-track) or after a 12-week wait (standard best practice). Face to face interviews were conducted at baseline (before intervention), and at 4-6, 10-12 (before intervention for the standard-practice group), 16-18 and 22-24 weeks with patients and their carers using standard questionnaires to assess symptoms, palliative care outcomes, function, service use and open comments. The investigators choice of outcomes was based on a systematic literature review of outcome measures.
