In 2012, the Centers for Disease Control and Prevention (CDC) initiated its multi-site clinical assessment of ME/CFS (MCAM) study, enrolling and following ME/CFS patients recruited from multiple specialized clinics in order to facilitate systematic collection of data on measures of their illness. MCAM helps “describe the differences and similarities among ME/CFS patients, which will be used to evaluate the ME/CFS case definition.” Ultimately, this study aimed to improve how ME/CFS is diagnosed and treated, as well as to shed more light on the underlying biology of the illness.”
A key feature of the study was reliance on the clinical experience of physicians who specialize in the identification and management of ME/CFS patients rather than on a prespecified case definition. Healthy people and those with other illnesses that share some features with ME/CFS were enrolled in comparison groups.
The CDC has published its first paper from the MCAM study, “Multi-Site Clinical Assessment of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (MCAM): Design and Implementation of a Prospective/Retrospective Rolling Cohort Study.” Co-authored by multiple ME/CFS experts, the paper provides detailed information on the design of this multisite clinical investigation of ME/CFS, as well as descriptive information about participants enrolled in stage 1 of the study, which was limited to participants with ME/CFS.

In March, Solve hosted Dr. Elizabeth Unger, chief of Chronic Viral Diseases Branch at Centers for Disease Control and Prevention, and her CDC colleagues to share updates and progress on The School-Based Active Surveillance Project (presented by Anindita Nanda Issa, MD), the Long Covid Fatiguing Illness Recovery Program (ECHO) (presented by Jennifer Cope, MD, MPH), and initial findings from the Multi-site Study of Post-COVID conditions (Medical chart abstraction project) (presented by Miriam Nji, MD, MPH)
