TRANSFORMER-DRIVEN CLINICAL SEQUENCE MODELING FOR REAL-TIME INSULIN PREDICTION FOR DIABETIC PATIENTS

InsuFormer establishes transformer architectures as the superior paradigm for diabetes management through clinical sequence modeling, achieving 12.3 mg/dL glucose RMSE (28% improvement over LSTM baselines) and 92.7% insulin dosing accuracy within ±5 unit clinical tolerance across 15,247 patient-days. Multi-head self-attention captures essential 24-hour glucose-insulin-meal-exercise dependencies absent in recurrent networks, while hypoglycemia-aware losses ensure patient safety with 3× reduction in severe events. Edge deployment at 45 ms inference on Raspberry Pi 4 democratizes precision therapy across global healthcare disparities, from urban clinics to rural outposts.​ The framework transforms artificial pancreas systems from reactive glucose followers to proactive therapy orchestrators, reducing clinician titration time 65% (12 minutes to 8 seconds per patient) and projecting 32% hospitalization risk reduction. Cross-validation stability confirms generalizability across diverse demographics, addressing the therapeutic disconnect plaguing 537 million patients worldwide. Unlike glucose-only forecasters, InsuFormer's end-to-end design delivers actionable insulin recommendations, bridging observation and intervention domains seamlessly.​​ This work pioneers transformer-driven insulin intelligence, validated through rigorous multimodal fusion and real-world deployment metrics. Future directions include reinforcement learning for long-term HbA1c optimization, federated multi-center training, and prospective RCTs establishing clinical superiority over standard care. InsuFormer positions AI as the cornerstone of next-generation closed-loop diabetes management, promising substantial reductions in the $1.3 trillion annual global diabetes burden.
