We assessed the patient pathway to rheumatology referral, including HCP recognition of inflammatory back pain (IBP) and other features suggestive of AS, diagnostic workup, treatment, and referral to a specialist with the goal of identifying barriers to patient referral to a rheumatologist.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>US HCPs from 10 specialties were invited to participate in a cross\u2010sectional web\u2010based survey on clinical characteristics and diagnostic measures leading to IBP suspicion and the subsequent referral process.

Nearly two\u2010thirds of primary care HCPs reported that they were the first HCPs consulted by patients with suspected IBP. Among HCPs ordering diagnostic blood work, approximately\u00a090% selected antinuclear antibody and rheumatoid factor, whereas 76% selected human leukocyte antigen B27. Almost 40% would treat patients with suspected IBP themselves.
