Integrated care boards (ICBs) are responsible for commissioning specialist myalgic encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS), services that meet the needs of their population, subject to local prioritisation and funding. The process of commissioning services should take into account best practice guidance, such as the National Institute for Health and Care Excellence’s (NICE) guidance on ME/CFS diagnosis and management, published in October 2021. The Department funds research into ME/CFS through the National Institute for Health and Care Research (NIHR). The NIHR, together with the Medical Research Council, is funding the world’s largest genome-wide association study of ME/CFS. This £3.2 million study, termed DecodeME, will analyse samples from 25,000 people with ME/CFS to search for genetic differences that may indicate underlying causes or an increased risk of developing the condition. A decision on the next steps for ME/CFS at the national level will be taken in the coming weeks.
