An artificial intelligence-based gout management system reduced chronic kidney disease incident and improved target serum urate achievement.

Abstract

Stage ≥3 chronic kidney disease (CKD) affects ∼25% of people with gout. The effects of urate-lowering therapy (ULT) on CKD incidence and progression have remained inconclusive. Here, we assessed the impact of a gout ULT clinic intervention using artificial intelligence (AI) on CKD incidence and achievement of serum urate (SU) target. An observational study compared propensity score (PS)-matched gout cohorts from an AI-based Gout Intelligent Management System (GIMS) and a standard Electronic Medical Records system (EMRS) clinic database. The GIMS included a mobile application, data fusion interface and modules for expert consultation and laboratory results management. All patients had gout and a starting estimated glomerular filtration rate >60 ml/min. Using a 1:2 PS-matched cohort study design, we assessed the impact of the AI-based system on CKD outcomes and ULT effectiveness over 4 years of follow-up. Compared with EMRS, GIMS was associated with reduced incidence of CKD stage ≥3. Specifically, 169/4117 new-onset CKD stage ≥3 (incidence 4.1 per 100 person-years) with GIMS compared with 164/2128 with EMRS (incidence 7.7 per 100 person-years) during follow-up. More participants achieved SU <6.0 mg/dl with GIMS versus EMRS during follow-up (49.8% vs 25.9%, P < 0.001). Application of the artificial intelligence-based Gout Intelligent Management System was associated with lower incidence of chronic kidney disease stage ≥3 and superior target serum urate achievement in people with gout. The Gout Intelligent Management System represents a novel approach to improve real-world renal outcomes and urate-lowering therapy success in gout.
