A Computational Audit of Demographic Association Encoding in ClinicalBERT Language Predictions
arXiv:2606.14460v1 Announce Type: new Abstract: Transformer-based clinical language models are increasingly integrated into high-stakes clinical decision support pipelines, yet the computational mechanisms through which demographic associations encoded in medical documentation propagate into model probability distributions remain empirically underspecified. We present a systematic computational audit of representational bias in ClinicalBERT (Alsentzer et al., 2019), a BERT-based model pretrained on MIMIC-III discharge summaries, employing two complementary probing methodologies: Log Probabilit
The increasing integration of transformer-based clinical language models into high-stakes decision support necessitates a deeper understanding of underlying biases before widespread deployment.
This research highlights the critical issue of demographic bias encoding in AI models within sensitive sectors like healthcare, impacting fairness, safety, and trust in AI-driven decisions.
There will be increased scrutiny on the representational biases in clinical AI models, leading to demand for more transparent, auditable, and ethically developed AI systems in healthcare.

- · Healthcare AI auditing firms
- · Developers of bias-mitigation techniques
- · Developers of unaudited clinical AI
- · Healthcare providers deploying biased models
- · Patients negatively impacted by biased AI decisions
Clinical AI models may face stricter regulatory hurdles and public skepticism due to identified demographic biases.
There will be an increase in funding and research dedicated to developing robust methods for identifying and mitigating bias in large language models for critical applications.
This could lead to a broader re-evaluation of deployment strategies for AI across other high-stakes domains, emphasizing 'ethics-by-design' principles from inception.
