Researchers have developed OC-Distill, a novel two-stage framework designed for improved ICU risk prediction using machine learning. The first stage employs an ontology-aware contrastive objective that leverages the ICD hierarchy to learn clinically grounded patient representations by quantifying patient similarity. The second stage refines the pretrained encoder through cross-modal knowledge distillation, transferring information from clinical notes into the model. This approach allows the model to utilize vital signs for inference while benefiting from the rich context provided by clinical notes during training, achieving state-of-the-art performance on MIMIC datasets.
