Real-world outcomes of a dedicated fast-track polymyalgia rheumatica clinic.

Objective: To examine the clinical impact of a fast-track PMR clinic to enable early diagnosis and treatment, and to define both patient and disease characteristics in newly diagnosed PMR.

Methods: Primary care physicians were invited to refer patients with new PMR to our fast-track clinic. Referral criteria included new onset shoulder or pelvic girdle pain and/or stiffness with elevated inflammatory markers in patients over 50 years. All patients were seen within 72 h of referral. Patients with a rheumatology diagnosis of PMR had an US of their temporal and axillary arteries.

Results: 172 patients were referred from primary care over 12 months. 39% of patients referred with suspected PMR had an alternative diagnosis for which PMR regimen glucocorticoids was inappropriate. 55% of the non-PMR diagnoses were other inflammatory rheumatological conditions requiring follow-up. Only 20% of patients referred from primary care already on glucocorticoids were commenced on bone protection. PMR patients were comorbid, with a mean of 2.5 other conditions. 75% of PMR patients experienced a glucocorticoid-related adverse event in the first 12 months of treatment. 17% of patients with new PMR had US features of subclinical GCA.

Conclusions: The commencement of glucocorticoid therapy should be deferred until after specialist evaluation to enable an accurate clinical diagnosis. A delay in treatment can only realistically be avoided if general practitioners have access to a fast-track PMR clinic. We believe that rheumatologists should consider establishing fast-track PMR clinics and this study provides a strong case for and a template to support this practice innovation.
