Use of primary health care and radiological imaging preceding a diagnosis of rheumatoid arthritis: a nationwide cohort study in Denmark.

Increased contacts to general practitioners and physiotherapists were seen in all 12 months preceding the RA diagnosis, intensifying in the last 6 to 8 months. Imaging increased from 3 months before the diagnosis. This indicates an opportunity to expedite referral to specialist care and ensure earlier diagnosis of RA.
