COVID-19 Public Health HL7 Reporting Integration

For healthcare organizations, HL7 is more than a standard — it is the backbone of clinical interoperability. Yet implementing HL7 across multiple systems, vendors and workflows often becomes complex, resource-intensive and difficult to maintain.

This organization found itself at precisely that crossroads.

As patient volumes increased and new systems were introduced, the number of required HL7 interfaces expanded rapidly. Internal teams were spending more time troubleshooting brittle custom integrations than focusing on innovation. Leadership needed a sustainable, scalable integration strategy — not just another interface engine.

After careful evaluation, the organization selected PilotFish for its healthcare expertise, flexible architecture and hands-on, consultative implementation approach. What followed was not simply an HL7 deployment, but the creation of a long-term interoperability foundation.

Implementing HL7 is rarely just about moving messages from Point A to Point B. The real challenge lies in normalization, validation and adaptability.

The organization required:

• Reliable handling of multiple HL7 message types (ADT, ORM, ORU, SIU)
• Support for customized HL7 segments and local variations
• Automated validation and acknowledgment handling
• Secure, auditable transport mechanisms
• Reusable components to reduce development effort
• Minimal disruption to existing clinical workflows

Most importantly, the solution had to remain viable as standards evolved — including future expansion into FHIR and API-driven interoperability.

PilotFish engineers worked closely with the client’s technical team to review existing HL7 specifications and identify normalization opportunities. Instead of layering custom scripts on top of inconsistencies, PilotFish implemented a structured transformation model.

Using the eiPlatform’s graphical Data Mapper, the team built reusable transformations capable of:

• Parsing inbound HL7 messages
• Validating segments and required fields
• Normalizing data into a common internal format
• Constructing outbound HL7 messages tailored to each receiving system

Because the architecture supports transformation from virtually any format to any other, variations in HL7 structure no longer required separate hard-coded solutions.

Partnership Over Project

From the outset, PilotFish operated as an extension of the client’s team.

A senior Solutions Architect led the initial implementation, mentoring internal staff and ensuring knowledge transfer was embedded into every phase. Design decisions were explained, not simply delivered.

This collaborative model allowed the organization to:

• Quickly understand interface design principles
• Gain confidence in modifying mappings
• Build new interfaces independently
• Reduce long-term reliance on outside consultants

The result was empowerment, not dependency.

Operational Stability and Strategic Agility

From an operational standpoint, the organization experienced immediate improvements:

• More reliable HL7 message processing
• Fewer production errors
• Faster interface deployment
• Improved data accuracy across systems

From a leadership perspective, the value was even greater.

The PilotFish architecture created a sustainable integration layer capable of supporting:

• New clinical systems
• Additional facilities
• Expanding partner networks
• Emerging interoperability standards

Rather than reacting to integration challenges, the organization could now proactively plan for growth.
