MICA · FIRST-LINE LEARNING NOTES
Understand, prioritise and organise follow-up
In first-line care, distinguish joint pain without objective inflammation, persistent synovitis and an acutely inflamed joint that may be infected.
Describe the pattern and confirm synovitis
Document distribution, joint count, symmetry, duration, stiffness and relation to activity. Look for swelling, warmth, effusion and restricted movement, distinguishing joint, tendon and muscle pain. Examine skin, nails and other systemic features. An acutely red, hot single joint requires immediate consideration of infection even in someone with known gout.
[1][2]Link testing to examination
Suspected rheumatoid arthritis starts with clinical synovitis; rheumatoid factor and anti-CCP may support it, but negative results do not exclude it. Suspected septic arthritis requires an urgent pathway for aspiration and microbiology. Serum urate alone does not establish the cause of joint inflammation. Typical osteoarthritis may be diagnosed clinically; atypical findings or competing diagnoses justify imaging.
[1][2][3]Distinguish joint pain from synovitis through swelling, warmth, limitation and distribution. An acutely hot painful joint raises concern for infection even with known gout; serum urate alone does not decide the diagnosis. Persistent small-joint or multiple-joint synovitis warrants early referral despite normal inflammatory markers or negative autoantibodies.
[1][2]Preserve timely diagnosis
Refer promptly for unexplained persistent synovitis, especially with multiple joints or small hand and foot joints involved. Do not wait for all immunology results before referral. Analgesic decisions should account for kidney function, gastrointestinal risk, anticoagulants and comorbidities. Severe pain with fever, systemic illness or major functional loss strengthens the need for immediate assessment.
[1][2][3]- Suspected septic arthritis requires urgent assessment and joint sampling through the appropriate pathway.
- Do not postpone rheumatology assessment while awaiting abnormal radiographs or every antibody result.
- Document stiffness, swelling and functional effects to compare findings across consultations.
Assess function and objective evolution
Record swollen joints, pain, independence and effects on work or walking. Review the course and whether specialist assessment actually occurred. Normal CRP does not negate persistent synovitis; minimal radiographic change does not exclude early inflammatory arthritis. Explain reasons to seek assessment before the appointment, including a suddenly hotter, more painful joint or associated fever.
[1][2]A learning situation
FICTIONAL CASE · SELF-REFLECTION WITHOUT A SCORE
A 42-year-old woman has had swollen wrists and metacarpophalangeal joints for several weeks with prolonged morning stiffness. Rheumatoid factor is negative and CRP normal. She is waiting for another blood test before rheumatology referral.
Do these results justify postponing referral?
Read the reasoning
No. Persistent synovitis and its distribution warrant prompt specialist assessment despite negative markers. Further investigations can proceed in parallel, with documentation of affected joints and functional impact. The aim is early recognition of inflammatory arthritis, not diagnosis based on one antibody alone.
