Evidence Checklist: Rheumatoid Arthritis

Rheumatology evaluation with ACR/EULAR diagnostic criteria documentationCritical

Evaluation by a rheumatologist documenting swollen and tender joint counts, disease activity scores (DAS28, CDAI), and classification per ACR/EULAR 2010 criteria.

Nexus opinion linking rheumatoid arthritis to service ("at least as likely as not")Critical

A medical opinion connecting RA to military service, including environmental exposures (silica, combustion products), physical stress, or immune dysregulation triggered by service conditions.

Rheumatoid factor (RF) and anti-CCP antibody resultsCritical

Serological tests including rheumatoid factor and anti-cyclic citrullinated peptide (anti-CCP) antibodies, along with inflammatory markers (ESR, CRP) documenting active disease.

Imaging showing joint erosions, synovitis, or joint space narrowing

Radiographs or MRI demonstrating periarticular erosions, joint space narrowing, or synovial thickening characteristic of rheumatoid arthritis. Ultrasound can show synovial hyperemia.

Documentation of systemic manifestations (anemia, fatigue, nodules)

Records documenting extra-articular manifestations including rheumatoid nodules, anemia of chronic disease, pericarditis, pleuritis, Sjogren's overlap, or eye involvement.

Treatment records (DMARDs, biologics, steroids)

Records documenting DMARD therapy (methotrexate, hydroxychloroquine, sulfasalazine), biologic agents (TNF inhibitors, IL-6 inhibitors), and corticosteroid use with disease activity assessments.

Buddy statement from spouse, family, or fellow service member

A written statement from someone who can describe observable symptoms and how your condition affects daily life.

Personal statement describing symptoms and functional impact

Your own written account of how this condition affects your daily activities, work, and relationships. Describe your worst days.

Completed DBQ Joint ConditionsCritical

Standardized form capturing range of motion of all affected joints, pain, inflammation, and functional limitations.

Service treatment records (STRs)Critical

Military medical records showing in-service treatment, complaints, or injuries related to this condition.
