Using a retrospective cohort of 7,667 patient encounters diagnosed with AKI from the University of California San Diego Health, we compared traditional machine learning (ML) and temporal deep learning (DL) models to predict three AKI recovery outcomes: Recovery, Partial Recovery, and Non-Recovery. The ML models evaluated were Logistic Regression, Random Forest, and XGBoost; while, the DL models were Gated Recurrent Unit (GRU) and Long-Short Term Memory. On the test set, DL models consistently outperformed traditional ML approaches. The GRU model achieved the highest Macro-Area Under the Curve (AUC) (0.822) with strong discrimination for the Non-Recovery class (AUC 0.932).

Forty clinicians participated in a 60-day pilot during which the AI scribe generated draft notes from encounter audio. Pre- and post-implementation surveys included validated single-item burnout measure, workflow assessments, NASA Task Load Index (NASA-TLX) scores, and EHR-autologged data on after-hours documentation. Clinicians reported significant reductions in perceived documentation time and after-hours work (all p < 0.001), with large effect sizes (r = 0.73-0.80). NASA-TLX domains demonstrated significant decreases in mental demand, physical demand, effort, time pressure, and stress (all p ≤0.001; g = 0.76-1.54). In contrast, objective EHR documentation minutes did not change significantly (t (15) = 1.52, p = 0.15, g = 0.36).

In this study, we examine how enhancing fairness through bias mitigation techniques reshapes Shapley-based feature rankings. We quantify changes in feature importance rankings after applying fairness constraints across three datasets: pediatric urinary tract infection risk, direct anticoagulant bleeding risk, and recidivism risk. We also evaluate multiple model classes on the stability of Shapley-based rankings. We find that increasing model fairness across racial subgroups can significantly alter feature importance rankings, sometimes in different ways across groups.

Traditional computational models for HF read-mission often rely on expert-crafted rules, medical thesauri, and ontologies to interpret clinical notes, which are typically written under time pressure and may contain misspellings, abbreviations, and domain-specific jargon. We present ClinNoteAgents, an LLM-based multi-agent framework that transforms free-text clinical notes into (1) structured representations of clinical and social risk factors for association analysis and (2) clinician-style abstractions for HF 30-day readmission prediction. We evaluate ClinNoteAgents on 3,544 notes from 2,065 patients (readmission rate=35.16%), demonstrating high extraction fidelity for clinical variables (conditional accuracy ≥90% for multiple vitals), key risk factor identification, and preservation of predictive signal despite 60-90% text reduction.
