Early Warning of Intraoperative Adverse Events via Transformer-Driven Multi-Label Learning
Intraoperative adverse events pose significant risks to patient safety and long-term prognosis. This cutting-edge research introduces IAENet, a novel Transformer-based multi-label learning framework, capable of providing accurate early warnings for six critical adverse events during surgery. By addressing challenges in data heterogeneity, class imbalance, and inter-event dependencies, IAENet significantly improves prediction accuracy, paving the way for proactive clinical interventions and enhanced patient outcomes.
Executive Impact: Enhancing Patient Safety & Operational Efficiency in Healthcare
Leveraging advanced AI, our system identifies high-risk patients for proactive interventions, reducing preventable harm and improving surgical outcomes. This translates into tangible benefits for healthcare enterprises by minimizing complications, optimizing resource allocation, and ultimately delivering superior patient care.

Pioneering Multi-Label Adverse Events Dataset (MuAE)
The MuAE dataset, the first of its kind, comprises six critical intraoperative adverse events (Hypotension, Low DoA, Arrhythmia, Hypoxemia, Hypothermia, Hypocapnia). It was meticulously constructed from the VitalDB dataset, involving rigorous data cleaning and preprocessing from 873 non-cardiac surgeries. This dataset addresses a crucial gap in multi-adverse event prediction research, providing a rich foundation for developing robust early warning systems.

Time-Aware Feature-wise Linear Modulation (TAFILM)
The Time-Aware Feature-wise Linear Modulation (TAFILM) module is a novel component inspired by FiLM, adapted for time series data. It dynamically modulates static covariates and dynamic vital signs through learnable affine transformations. This approach effectively fuses heterogeneous clinical data, reducing redundancy and noise, thereby enhancing feature quality within the Transformer encoder for improved temporal dependency modeling.
By leveraging TAFILM, IAENet ensures that crucial static patient information (like age, weight, ASA class) is intelligently integrated with real-time physiological signals (like blood pressure, heart rate, SpO2), allowing the model to adapt its feature processing based on the unique context of each patient's condition throughout surgery.
Label-Constrained Reweighting Loss (LCRLoss)
Addressing the inherent class imbalance and inter-label dependencies in medical datasets, IAENet introduces the Label-Constrained Reweighting Loss (LCRLoss). This innovative loss function dynamically reweights prediction outputs based on batch-wise label frequency and incorporates a co-occurrence regularization term. This dual approach ensures structured consistency among frequently co-occurring events, mitigating imbalance and improving model robustness and generalization.
