Fibromyalgia: Misdiagnosis Rates Are High


A study published in Arthritis Care & Research suggests there’s only a fair amount of agreement between fibromyalgia diagnoses in the United States and established diagnostic criteria for the condition — meaning that many people told by their health care provider they have fibromyalgia actually may not.

This study, led by a researcher from the National Data Bank for Rheumatic Diseases, involved 497 people who completed health assessment questionnaires and questionnaires assessing fibromyalgia diagnostic variables used by the American College of Rheumatology at a rheumatology clinic. Study participants were also evaluated and diagnosed by rheumatologists — doctors who specialize in musculoskeletal diseases and systemic autoimmune conditions.

According to the researchers, 121 of the study participants met the diagnostic criteria for fibromyalgia and 104 were diagnosed with the condition. While overall agreement was more than 79 percent, agreement beyond chance was just fair. Doctors failed to identify 60 people who met the diagnostic criteria for fibromyalgia and incorrectly diagnosed 43 others with fibromyalgia who didn’t meet the criteria.
