HABITAT System Architecture

The CBMI Research Data Warehouse is a secure, unified resource designed to support high-quality, data-driven biomedical and clinical research. HABITAT operates a secure, hybrid-cloud infrastructure across AWS and Snowflake, governed by an approved MU IRB and strict Standard Operating Procedures (SOP).

Data Governance

  • HIPAA & Institutional Compliance
  • IRB-approved data release workflows
  • Minimal data release policy
  • Role-based access & audit logging

Key Features

  • Standardized Common Data Models
  • Validated Privacy Pipeline
  • Longitudinal Care Sequences

1. Bronze Layer

Raw Ingestion: Direct nightly ingestion of source systems in original form to ensure data consistency.

2. Silver Layer

Standardization: Unified linkage via Master Patient Index and mapping to global common data models.

3. Gold Layer

Research Backing: This layer provides curated, analytics-ready tiers (Identified, Limited, and Anonymized) that directly support research initiatives.

Integrated Data Sources

MU Health Care EMR

Encounters, diagnoses, procedures, labs, vitals, medications, and clinical observations.

MUHC Billing & Pharmacy

Diagnosis/procedure codes (ICD, CPT, HCPCS) and structured medication orders and dispensing data.

CoPathPlus

Selected structured pathology variables.

External Data Sources
  • Socio-economic and Environmental Data
  • Genomics and Cancer Registry
Unstructured Data

Transforming clinical notes to support advanced NLP and LLM research workflows.

Privacy & Anonymization Pipeline

Identifier Handling

Direct identifiers are removed or transformed per institutional policy.

Anonymized Date Shifting

Dates are shifted backward (up to 365 days) to protect privacy while preserving temporal integrity.

Temporal Integrity

Consistent per-patient shifts ensure time-to-event studies remain accurate without exposing identifiable dates.

Security Controls

Aligned with NIST SP 800-53 moderate standards with continuous security monitoring.

Standardized Common Data Models

OMOP Data Model ↗

Maintained by OHDSI, supporting standardized analytics across global networks.
