Transforming healthcare data using medallion architecture: How CareEvolution turns raw data into analytically-ready gold

In the world of modern data engineering, the medallion architecture has emerged as a powerful paradigm for organizing and refining data. By structuring data across Bronze, Silver, and Gold layers, organizations can progressively improve data quality and usability, enabling high-value insights and decisions.

CareEvolution® understands the critical importance of this architecture and its role in healthcare data management.

The words data quality and data enrichment are used very liberally across healthcare but most data quality and enrichment would not win any medal, much less bronze. Putting all of the data in one place with minor formatting and organizing is not enough to support any healthcare organization’s true data quality and enrichment needs.

The Orchestrate APIs transform data at each step of the curation and enrichment process.

Data is logically organized to incrementally and progressively improve in structure and quality as it flows through each layer of the architecture.

Orchestrate APIs enable medallion architecture for healthcare data

The Orchestrate APIs transform data at each step of the curation and enrichment process. Data is logically organized to incrementally and progressively improve in structure and quality as it flows through each layer of the architecture. Each Orchestrate API endpoint serves a narrow, targeted use case- services can be employed as/when needed in a high performance pipeline.

What is medallion architecture?

Medallion architecture is a tiered approach to organizing data:

Bronze layer: Raw, unprocessed data as ingested from various sources. Think of this as your “data lake.”
Silver layer: Cleaned and standardized data, ready for analysis or basic applications.
Gold layer: Highly curated, enriched, and often aggregated data optimized for downstream analytics, machine learning, or business intelligence.

This progression ensures that data quality and structure improve as it moves through the pipeline, aligning with the organization’s goals and compliance requirements.

CareEvolution’s approach to medallion architecture

CareEvolution’s platform is uniquely positioned to support and enhance medallion architecture in healthcare contexts. Here’s how we help transform raw data into gold:

Bronze layer: Ingesting diverse healthcare data sources

The Bronze layer is all about handling raw data. CareEvolution’s platform excels at integrating data from a wide range of sources:

Electronic Health Records (EHRs)
Claims systems
Wearables and remote monitoring devices
Patient-reported outcomes (PROs)
Clinical trial platforms

Key benefits:

Seamless ingestion of structured, semi-structured, and unstructured data.
Flexibility to work with industry-standard formats like HL7, FHIR, and CSV, as well as custom schemas.
Secure, scalable handling of large datasets.

Silver layer: Cleaning and standardizing data

The transition from Bronze to Silver is where raw data becomes reliable. CareEvolution’s APIs allow automated data enrichment at this crucial step:

De-duplication and Reconciliation: Resolving duplicate patient records and normalizing data across sources.
Standardization: Mapping diverse data formats to standardized models like FHIR and OMOP.
Quality validation: Identifying gaps, errors, and inconsistencies to ensure clean, trustworthy data.

How it helps:

Automate & integrate admin workflows
Improved care coordination among providers
Accurate information for risk adjustment
Actionable data for value based care
Improve quality performance CMS STARS
Compliance with interoperability mandates

Gold layer: Enrichment and high-value insights

In the Gold layer, data is no longer just clean—it’s enriched, contextualized, and optimized for action. CareEvolution provides tools to:

Enhance data context: Add clinical, demographic, and social determinants of health (SDOH) insights to datasets.
Aggregate and curate: Create purpose-built datasets tailored to specific use cases like health plan risk adjustment or quality reporting (e.g., CMS Stars), clinical trials, or population health analytics.
Enable advanced analytics: Deliver data ready for machine learning models, predictive analytics, or business intelligence platforms.

Example in action: A health plan can use enriched Gold-layer data to identify at-risk populations, target interventions, and optimize care delivery—directly improving metrics like Star ratings and CMS Stars scores.
