How Retrieval Works

When you submit a query, Health Gorilla connects to national and regional health networks, retrieves the latest records, and normalizes them before delivery. Returned data depends on the source—for example, a hospital may provide a CCD summary and lab results, while a diagnostic lab may return only test results.

You don’t need to select networks or configure routing; the platform automatically handles endpoint discovery, patient matching, and document aggregation.

Connected Networks

Health Gorilla participates in major interoperability frameworks, including:

• Carequality: Query-based record retrieval from hospitals, health systems, and EHR vendors
• CommonWell: Bidirectional exchange with ambulatory and specialty practices
• eHealth Exchange: Broad network of health information exchanges (HIEs) and federal agencies
• TEFCA QHINs: Nationwide interoperability under federal rules
• California QHIOs: State-designated health information organizations that extend TEFCA connectivity and enable regional data exchange under the DxF framework
• State and Regional HIEs: Local networks that provide access to hospitals, community practices, and public-health agencies not covered by national frameworks
• Diagnostic Networks: National laboratories such as Quest Diagnostics and Labcorp, along with specialty labs, that deliver test ordering and results

The platform uses a federated query model to retrieve the most current information and return normalized, deduplicated records.

Routing and Record Discovery

You submit one API call, and Health Gorilla manages the entire process:

1. Match patient demographics using entity-resolution and referential data
2. Identify record locations through the Record Locator Service (RLS)
3. Dispatch queries using FHIR, HL7, or other supported protocols
4. Normalize and return results as FHIR resources in a consistent structure

Patient Identity Resolution

To support cross-network queries, Health Gorilla applies multiple identity-resolution methods:

• Internal algorithms that evaluate patient attributes
• Connected RLS services from TEFCA and other networks
• Referential matching through participating partners

These techniques enable high-confidence retrieval even when demographic data varies or is incomplete.

Data Contribution and Reciprocity

Your organization can also contribute structured clinical data back to these networks using FHIR write or $merge operations. Contributed records become available to authorized participants and support:

• Continuity of care
• TEFCA and other regulatory data-sharing requirements
• Collaborative documentation models across care teams

Health Gorilla routes submitted data through the same discovery and trust channels used for retrieval, so you don’t need to manage endpoint credentials or document packaging.

Delegation of Authority

Organizations participating through Health Gorilla can delegate data-sharing authority to affiliated entities—such as EHR vendors, health systems, or service providers—under an approved agreement. Delegation enables those entities to query or contribute data on the organization’s behalf while maintaining compliance with network and TEFCA policies.

Health Gorilla enforces this delegation at the platform level, ensuring all delegated actions are traceable, auditable, and governed by the principal organization’s permissions.
