Patent Pending · MIMIC-IV Validated · 17,000+ Disease Phenotypes

Decision-governance engine that surfaces clinically actionable signals.

The 9-layer GH-OS detects associations across 17,000+ disease phenotypes through federated knowledge graph inference and LLM reasoning. Fifteen MIMIC-IV classifiers are one layer of nine.

Designed to reduce alert fatigue — not amplify it.

9-Layer Decision Engine

Not a scoring model. DiviScan GH-OS is a decision-governance engine — layering biomarker ingestion, knowledge graph inference, ontology harmonization, and utility-weighted decision logic. Fifteen trained classifiers exist at one layer; the rest are rules, lookups, and structured reasoning.

Layer 01

Biomarker Ingestion

Multi-source lab and vitals intake with normalization across organ-system panels. Structured for downstream multi-omic inference.

Layer 02

Panel Analysis

Organ-system panel decomposition — hepatic, renal, cardiac, metabolic, hematologic — with cross-panel correlation mapping.

Layer 03

Federated KB Query

Parallel federated lookup across HPO, PrimeKG, Hetionet, PharmGKB, ClinVar, and DisGeNET. 11M+ relationships queried for differential enrichment.

Layer 04 — Multi-Ontology Integration (Sub-Layers 4a–4i)

Phenotype Mapping & Ontology Harmonization

Translates abnormal biomarker deviations into standardized phenotype terms across nine integrated ontology sub-layers, resolving cross-ontology conflicts into a unified inference representation.

Layer 05

Multi-Omic Inference

Fifteen MIMIC-IV-trained classifiers generate probability scores across conditions including Hepatic Failure, DIC, Acute MI, Cardiac Arrest, CKD, ARDS, Respiratory Failure, Heart Failure, Ischemic Stroke, Type 2 Diabetes, AKI, Sepsis, Electrolyte Disorders, Anemia, and Epilepsy/Seizures. This is the only trained-ML layer. All other disease associations are inferred via knowledge graph traversal, not trained models.

Layer 06

Utility Gate

Proprietary decision layer applying utility-weighted thresholds — not raw probability cutoffs. Context-sensitive alerting designed to reduce alert fatigue by filtering clinically non-actionable signals.

Layer 07

Cross-Organ Synthesis

Integrates signals across organ systems to detect multi-system deterioration patterns invisible to single-variable monitors or single-disease models.

Layer 08

Risk Stratification

Composite acuity scoring combining multi-omic inference outputs, utility gates, and temporal biomarker trajectories into actionable risk tiers across all three operational domains.

Layer 09

Intelligence Reporting

Structured output with organ-level breakdowns, confidence intervals, phenotype-gene evidence trails, cross-ontology reasoning chains, and domain-specific reporting for clinical, pharma, and population health consumers.

Three Domains, One Engine

Decision-governance across clinical, pharmaceutical, and population domains — delivering clinically actionable signals at each layer of the health infrastructure.

Clinical

Early Deterioration Detection

Move beyond NEWS/MEWS. The GH-OS processes routine lab panels and vitals through its 9-layer engine to surface multi-organ deterioration patterns before they become critical events.

  • Continuous multi-organ-system monitoring from existing lab data
  • Utility Gate alerting designed to reduce alert fatigue
  • Phenotype-backed evidence trails for decision support
  • MIMIC-IV validated across 15 disease classifiers (AUC 0.754–0.958)
Pharmaceutical

Trial Rescue Intelligence

Identify why trials fail before they fail. The simulation engine models biomarker trajectories across trial arms, detecting subpopulation signals and endpoint risks that traditional DSMB reviews miss.

  • Biomarker-driven enrollment stratification simulation
  • Subpopulation responder detection in failing Phase II/III trials
  • Endpoint sensitivity modeling across organ-system panels
  • $134,849,686 value demonstrated in 40-patient MIMIC-IV simulation
Population Health

Federated Learning Infrastructure

Population-scale knowledge graph inference without centralizing sensitive data. Federated architecture enables cross-institutional pattern detection across distributed health systems.

  • Federated knowledge-base inference across distributed nodes
  • Cross-institutional disease signal aggregation
  • Population-level phenotype frequency mapping
  • Privacy-preserving multi-omic pattern detection at scale

Infrastructure-Level, Not Tool-Level

Traditional early warning systems are single-domain scoring tools. EHR-embedded models apply raw probability thresholds. DiviScan GH-OS operates as a federated decision-governance engine spanning all three health domains simultaneously.

Capability Traditional EWS EHR-Embedded DiviScan GH-OS
Input Variables 6–7 vital signs EHR data fields Dozens of organ-system endpoints + federated KB
Scoring Method Aggregate threshold Single-model probability Utility-weighted decision governance
Knowledge Bases None None HPO, PrimeKG, Hetionet, PharmGKB, ClinVar, DisGeNET
Operational Domains Clinical only Clinical only Clinical + Pharmaceutical + Population Health
Disease Coverage General deterioration Single condition 17,000+ disease phenotypes (knowledge graph inference) + 15 AUC-validated ML classifiers
Alert Logic Fixed threshold Probability cutoff Utility Gate (designed to reduce alert fatigue)
Federated Learning No No Population-scale federated inference
Phenotype Inference No No 11M+ cross-ontology relationships

Clinical Utility Framework: Three-Condition Test

Signals are evaluated against three conditions before clinical deployment. Raw accuracy metrics alone do not determine clinical utility.

Condition 1 — Rightness

Rightness

Does the signal match known clinical truth? The output must be clinically coherent with established disease pathophysiology — not just statistically correlated.

Condition 2 — Novelty

Novelty

Does it surface signals beyond what standard alerting would catch? Utility requires detecting patterns invisible to NEWS/MEWS or single-variable monitors.

Condition 3 — Convincingness

Convincingness

Is the evidence trail interpretable by the clinician? Signals must be traceable to specific biomarker deviations and ontology relationships — not a black-box score.

Deployment Mode Utility Scoring
Mode Optimization Target Key Metric
Hospital Minimize alert fatigue, maximize actionability Sensitivity + Utility Gate pass rate
Pharma Subpopulation enrichment + endpoint risk detection Specificity + responder signal strength
Government Cross-institutional coverage + population signal breadth Coverage depth + phenotype frequency

What We Can Honestly Claim

Transparency is a design principle, not an afterthought.

Claim Status
17,000+ disease associations via knowledge graph inference YES
15 diseases with AUC-validated ML scores (MIMIC-IV) YES
9-layer decision-governance engine is operational YES
Provisional patent on Utility Gate methodology YES
MIMIC-IV retrospective validation (15 diseases) YES
LLM reasoning over biomedical ontologies for >17K diseases YES

Disclaimers: DiviScan GH-OS is not FDA cleared, has not been prospectively validated in live clinical settings, is not a replacement for clinical judgment, and not all disease associations are backed by trained ML — many are inferred via knowledge graph traversal.

Simulation-Backed Validation

AUC scores are secondary evidence for the 15 ML classifiers. Clinical utility is evaluated via the three-condition framework above. Transparent about stage — these are demonstration-level results with clear biological signal.

Scope: 15 diseases have AUC-validated ML scores (Hepatic Failure, DIC, Acute MI, Cardiac Arrest, CKD, ARDS, Respiratory Failure, Heart Failure, Ischemic Stroke, Type 2 Diabetes, AKI, Sepsis, Electrolyte Disorders, Anemia, Epilepsy/Seizures). All other disease associations — spanning 17,000+ phenotypes — are inferred through knowledge graph traversal and LLM reasoning over federated biomedical ontologies.
