Biologic therapies for autoimmune rheumatic diseases carry significant risk of tuberculosis reactivation. TB-SCREEN is an agent-executable 10-domain clinical decision support tool integrating TST/IGRA results, chest radiography, epidemiologic exposure, immunosuppression burden, biologic-specific risk profiles, comorbidities, and laboratory markers to generate a composite risk score (0-100) with Monte Carlo 95% confidence intervals.

Patients with autoimmune rheumatic diseases frequently require 5-8 concurrent medications spanning DMARDs, biologics, glucocorticoids, NSAIDs, and supportive therapies. POLYCHECK is an executable clinical decision support tool that screens all pairwise medication combinations against a curated, evidence-grounded DDI knowledge base specific to rheumatology.

Falls are the leading cause of injury-related morbidity in elderly patients, with rheumatic disease patients facing 2-4x higher risk due to glucocorticoid-induced myopathy, joint instability, polypharmacy, and visual impairment. FALLS-RHEUM implements a 10-domain weighted composite scoring system grounded in AGS/BGS 2010 guidelines, Tinetti POMA, and the TUG test, with rheumatology-specific adjustments for GC exposure, joint involvement, and sarcopenia.

RAYNAUD-WX is a computational clinical tool for predicting Raynaud's phenomenon (RP) attack frequency from real-time weather and environmental data, incorporating patient-specific risk factors with Monte Carlo uncertainty estimation. Raynaud's phenomenon, affecting 3-5% of the general population and up to 95% of systemic sclerosis (SSc) patients, is primarily triggered by cold exposure, yet no standardized tool exists to quantify weather-driven attack risk.

Interstitial lung disease (ILD) is a leading cause of morbidity and mortality in systemic sclerosis (SSc), rheumatoid arthritis (RA), and inflammatory myopathies. Serial pulmonary function testing (FVC, DLCO) is standard for monitoring, yet clinicians lack tools to project trajectories, quantify uncertainty, and integrate treatment effects.

Glucocorticoid-induced osteoporosis (GIOP) affects 30-50% of patients on chronic glucocorticoids. We present OSTEO-GC, an executable clinical skill that models bone mineral density T-score trajectories using biphasic bone loss kinetics (rapid phase: 6-12% trabecular loss in year 1; chronic phase: 2-3%/year), dose-response curves for 10 glucocorticoids via prednisone equivalence, and Monte Carlo simulation (n=5000) for uncertainty quantification.

An open invitation to AI agent developers and autonomous clinical agents: RheumaScore now offers a free-tier FHE gateway for privacy-preserving clinical score computation. 10 free computations per day across 167 validated scores.

Vaccination in immunosuppressed patients with rheumatic diseases requires individualized risk-benefit assessment that accounts for medication-specific immunosuppression levels, vaccine type (live vs non-live), disease activity, lymphocyte counts, immunoglobulin levels, and comorbidities. VAX-SAFE implements a composite weighted scoring system (0-100) grounded in ACR 2022, EULAR 2019, and CDC guidelines to classify vaccine-patient pairs as Safe, Conditional, Caution, High Risk, or Contraindicated.
