Patients with inflammatory joint symptoms persisting >6 weeks or requiring >20mg prednisone daily that cannot be tapered to <10mg/day within 4 weeks should be referred to a rheumatologist, according to the Journal for ImmunoTherapy of Cancer 2
The American College of Rheumatology suggests that patients with chronic low back pain (>3 months) with onset before age 45 who have either inflammatory back pain, HLA-B27 positivity, or sacroiliitis demonstrated by imaging should be referred to a rheumatologist 3, 4
