Initial Treatment for Arthritis in an Urgent Care Setting

Initial Assessment and Treatment Algorithm

The American College of Rheumatology suggests that arthritis is characterized by joint swelling associated with pain or stiffness, and clinical examination is the primary method for detecting synovitis in the urgent care setting, with initial laboratory tests including complete blood count, urinary analysis, transaminases, and antinuclear antibodies to exclude other conditions 4, 5, 6
Initial assessment should include evaluation of gastrointestinal, renal, and cardiovascular risks before considering NSAIDs as the first-line treatment for arthritis in an urgent care setting 1, 2, 3

The European League Against Rheumatism recommends NSAIDs as the recommended initial therapy for symptomatic relief of arthritis in the urgent care setting, with use at the minimum effective dose for the shortest time possible to minimize adverse effects 1, 2
For juvenile idiopathic arthritis with 4 or fewer affected joints and low disease activity, NSAID monotherapy is appropriate as initial treatment, according to the American Academy of Pediatrics 7
Intra-articular glucocorticoid injections should be considered for relief of local symptoms of inflammation, particularly for oligoarticular involvement, as suggested by the American College of Rheumatology 7, 2

Systemic glucocorticoids can be considered as a temporary adjunctive treatment to reduce pain and swelling, but should be limited to the lowest effective dose for the shortest duration possible (less than 6 months) to avoid cumulative side effects, according to the National Institute for Health and Care Excellence 1, 2
Intra-articular injections with triamcinolone hexacetonide are recommended and can provide clinical improvement for at least 4 months, as stated by the American Academy of Orthopaedic Surgeons 7

For patients with high disease activity and features of poor prognosis, consider initiating methotrexate without prior therapy, as recommended by the European League Against Rheumatism 7, 8
Following initial glucocorticoid joint injections, methotrexate should be considered for patients with high disease activity without poor prognostic features, according to the American College of Rheumatology 7

Disease activity should be assessed at 1-3 month intervals until treatment target is reached, including tender and swollen joint counts, patient and physician global assessments, ESR, and CRP, as suggested by the National Institute for Health and Care Excellence 2, 5, 8
Non-pharmacological interventions such as dynamic exercises and occupational therapy should be considered as adjuncts to drug treatment, according to the American College of Rheumatology 2, 5, 3

Continuing NSAID monotherapy for longer than 2 months in patients with active arthritis is inappropriate, as stated by the American College of Rheumatology 7
Failing to consider cardiovascular, renal, and gastrointestinal risks when prescribing NSAIDs is a common pitfall, according to the European League Against Rheumatism 1, 2
