What we need

We need evidence from the areas listed below for the guideline we are developing on Myalgic encephalomyelitis (or encephalopathy)/chronic fatigue syndrome: 

1. Studies that evaluate: 

  • Management strategies that are adopted while someone is being assessed for a diagnosis of ME/CFS.
  • Methods of monitoring and/or reviewing people with a diagnosis of ME/CFS

We are looking for trials that compare different strategies or different methods of monitoring and review. Systematic reviews, randomised controlled trials, non- randomised trials that are prospective or retrospective cohort studies will be considered for inclusion in the guideline.

We would like studies that report measurable outcomes on:

  • Mortality
  • Quality of life
  • Fatigue /fatiguability
  • Physical functioning
  • Cognitive function
  • Psychological status
  • Pain
  • Sleep quality
  • Treatment-related adverse effects
  • Activity levels
  • Return to school or work
  • Exercise performance measures.
  • Care needs
  • Impact on families and carers

We cannot accept non comparative studies, promotional material, non-evidence-based assertions of effectiveness or opinion pieces.

  1. Evidence on the experience of people who have had interventions for ME/CFS.

We are looking for evidence that explores and evaluates people’s experience of interventions for ME/CFS. Qualitative studies evaluating focus groups and interviews and surveys will be considered for inclusion in the guideline.

We cannot accept case series, case studies, individual accounts of experience, promotional material, non-evidence-based assertions of effectiveness or opinion pieces.

We are particularly interested in information promoting equality of opportunity relating to age, disability, gender, gender identity, ethnicity, religion and belief, sexual orientation or socio-economic status.
