Product
Marqi Index
A peer-reviewed, deployable risk score for 30-day readmission. Built on real clinical cohorts, validated against published benchmarks, and designed for EHR integration.
What Marqi Index Does
End-to-end risk stratification from data ingestion to clinical workflow integration.
Ingests Data You Have
Structured EHR fields and closed claims data. No clinical notes required for the current product. No new data collection or workflow change.
Predicts 30-Day Risk
A risk score for the six conditions in the CMS Hospital Readmissions Reduction Program, with an all-cause expansion in clinical validation.
Calibrated & Auditable
Every prediction includes a calibrated probability, a confidence interval, and a longitudinal patient view surfacing clinical signals.
Workflow Integration
Risk scores delivered to discharge planning, case management, and care coordination. Epic, Cerner, and FHIR-compatible environments.
Technical Architecture
Marqi Index is built on a 15-seed transformer ensemble with an XGBoost out-of-fold meta-learner. The architecture is designed for reproducibility, auditability, and deployment at scale.
15-Seed Ensemble
Multiple random seeds for training stability and uncertainty quantification.
Transformer + XGBoost
Deep learning feature extraction with gradient boosting meta-learner.
No PHI in Features
Model uses only structured fields. No clinical notes for Paper 1.
Full Calibration
Calibration plot, intercept, slope, and Brier score reported per validation.
