HANDROM is an executable clinical decision-support skill that estimates hand impairment from range-of-motion loss, grip and pinch weakness, inflammatory burden, pain/stiffness, and functional difficulty. It returns a severity category, uncertainty interval, referral recommendation, and red-flag notes for rheumatic disease care.
RA-MODEL is an executable Python skill that consolidates standard rheumatoid arthritis disease-activity and function indices into one transparent longitudinal workflow. It computes DAS28-CRP, DAS28-ESR, CDAI, SDAI, Boolean remission, HAQ-DI, RAPID3, and a treat-to-target summary across serial visits.
MTX-PNEUMO is an executable Python clinical skill for transparent methotrexate-associated pneumonitis risk stratification in rheumatic and autoimmune disease. The model integrates age, time since methotrexate initiation, weekly dose, pre-existing ILD/fibrosis, abnormal baseline chest imaging, prior DMARD lung toxicity, diabetes, hypoalbuminemia, CKD, dyspnea, dry cough, fever, hypoxemia, eosinophilia, diffuse interstitial or ground-glass imaging pattern, and whether infection has been excluded.
Leflunomide-associated interstitial lung toxicity is uncommon but clinically important because presentations can be abrupt, severe, and difficult to separate from rheumatoid arthritis-associated interstitial lung disease or pulmonary infection. The bedside problem is not merely whether the adverse event is rare.
Fibromyalgia overlap commonly inflates composite disease activity measures in rheumatoid arthritis and related inflammatory rheumatic disease, creating risk of unnecessary biologic or immunosuppressive escalation. We present FIBRO-OVERLAP, an executable transparent clinical skill that integrates subjective symptom burden, objective inflammatory markers, tender-to-swollen joint mismatch, optional 2016 fibromyalgia criteria support, and imaging context to estimate likely fibromyalgia-driven inflation of apparent inflammatory activity.
Executable RA disease model: DAS28-CRP/ESR (Prevoo 1995), CDAI/SDAI (Aletaha 2005), Boolean Remission (Felson 2011), RAPID3, HAQ-DI, and EULAR Treat-to-Target (Smolen 2023 DOI:10.1136/ard-2022-223356).
Autoimmune diseases encompass a spectrum of disorders characterized by loss of immune tolerance and immune-mediated tissue damage.
