Appraisal of Clinical Practice Guideline: National Institute for Health and Care Excellence (NICE) clinical practice guideline for myalgic encephalomyelitis (or encephalopathy)/chronic fatigue syndrome: diagnosis and management

The guideline aims to improve awareness and understanding of the diagnosis and management of ME/CFS in adults and children. It revised the previous guideline with a paradigm shift away from the belief that ME/CFS is a psychogenic condition.

It covers multidisciplinary, person-centred care involving: family/carers; joint decision-making; effective communication; diagnosis and assessment; provision of a support plan; self-management; managing comorbidities and illness fluctuations; long-term support and review; educational and vocational support; and the need for a skilled and knowledgeable workforce.

The most important and relevant change for physiotherapists is rejection of the notion that ME/CFS is caused by deconditioning, ‘dysfunctional illness beliefs’ or ‘exercise avoidance’.

Specifically, the guidelines state that people with ME/CFS should not be offered exercise-based treatments, unless the person feels ready to progress. If so, exercise should be overseen by a specialist ME/CFS physiotherapist and include regular review, information about the potential risks, how to recognise and manage a flare-up, and very careful flexible adjustments to activity levels within the individual’s energy limits.

The 2021 NICE guidelines for ME/CFS heralded a paradigm shift in the understanding and management of ME/CFS. It recognised ME/CFS as a complex multi-system disease, rather than a psychogenic disorder, and rejected cognitive behavioural therapy and graded exercise therapy as curative treatments.

This acknowledged the ‘patient’s voice’, which had been highlighting the harm done by these treatments for many years. The recommendations in the guidelines were drawn from 10 evidence reviews, which downgraded the quality of most trial evidence that had been the foundation of previous guidance.

The guideline committee had strong representation from people with lived experience of ME/CFS (both lay and professional representatives) and sought to integrate people’s lived experience by including evidence from qualitative research within best-evidence reviews.

NICE’s guidance, policies and processes were meticulously followed and closely scrutinised at every stage, as the content was considered controversial by those who were reluctant to accept that ME/CFS was not psychosomatic.

To better understand the needs of two particularly underserviced groups, NICE commissioned studies to examine the experiences of children and young people with ME/CFS, and people with severe/very severe ME/CFS when seeking healthcare. This supplemented the limited evidence in these areas. NICE also took three expert testimonials to better understand specific issues and led extensive stakeholder consultations.

The result is a high-quality guideline that has changed the understanding of ME/CFS and its management. This guideline has been welcomed by people with ME/CFS, ‘patient’ organisations and most clinicians and services. Useful resources have been produced to guide implementation of the guidelines, support service improvement and structure audit.
