The Heart-Failure Feature Kept Its Evidence Trail
An automated pipeline built structured and rubric-scored variables from nine EHR tables, then linked each output back to its support.
Summary
An automated pipeline built structured and rubric-scored variables from nine EHR tables, then linked each output back to its support.
The Nimblemind Multi-Agent System generated 132 structured and 70 rubric-scored aggregate features from nine electronic-health-record tables and attached evidence and rubric provenance. On 500 dummy patient records from one institution, adding the aggregates raised held-out AUROC from 0.895 to 0.963 for reduced-ejection-fraction phenotyping and from 0.870 to 0.910 for preserved-ejection-fraction phenotyping. The authors call for external validation; this was feature-engineering research, not a clinical diagnostic trial.
