aceAugmenting electronic health records for adverse event detection
Objective Adverse events (AEs) resulting from medical interventions are significant contributors to patient morbidity, mortality, and healthcare costs. Detection of these events using electronic health records (EHRs) can facilitate timely clinical interventions. However, effective detection remains challenging due to severe class imbalance, missing labels, and the complexity of EHR records. Classical machine learning approaches frequently underperform due to insufficient representation of minority adverse event…
TASER-AE, a tokenized augmentation method paired with a transformer classifier, reached minority-class F1 scores up to 0.67 for adverse event detection, outperforming classical machine-learning baselines and generative augmentation.
The source reports only dataset experiments and describes patient safety benefits as potential, so real-world clinical impact is not demonstrated.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-1938 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
