The first retrospective cohort study of the #functional #medicine model has recently been published in the Journal of American Medical Association Network Open (#JAMA). The study saw researchers from the Cleveland Clinic’s Center for Functional Medicine examine 1,595 patients they had treated there, as well as 5,657 patients seen in primary care at a family health centre. All patients had their health-related quality of life (#QoL) assessed using a patient-reported outcomes measurement information system (#PROMIS). The National Institute of Health (#NIH) validated questionnaires, measured patients physical and mental health across a period of 12 months.
