Overview

The client required their ECG platform to transmit reports directly to hospital systems such as Epic and DICOM repositories. However, the platform generated ECG reports in XML format and lacked support for interoperability standards such as HL7 and DICOM, preventing seamless integration with hospital IT infrastructure.

Dash Technologies implemented a healthcare interoperability integration framework enabling ECG reports to be transmitted to Epic and DICOM systems using HL7 standards.

About the Client 

The client develops an ECG diagnostic solution used by healthcare providers to capture and analyze cardiac data. Their platform enables clinicians to generate detailed ECG reports for cardiac diagnosis and monitoring. 

Eliminated 10–15 hours/week  of manual effort with an event-driven ECG integration engine

Business Challenges

Although the ECG platform generated detailed cardiac diagnostic reports, it could not transmit them directly to hospital systems such as Epic or diagnostic repositories using DICOM standards. This created several operational and business challenges.

  • ECG Data Silos

    Without interoperability support using HL7 and DICOM, ECG reports stayed within the diagnostic platform instead of becoming part of the hospital’s central patient record.

  • Delayed ECG reports

    Manual ECG report workflows meant reports could take 30–45 minutes to appear in hospital systems, slowing access to critical cardiac diagnostic data. 

  • Manual report sharing increased operational effort

    Healthcare teams often had to export and transfer ECG reports manually. For hospitals performing 100–150 ECG tests per day, this could require 10–15 hours of administrative effort per week.

  • Higher integration effort for hospitals

    Lack of HL7 and DICOM interoperability forced hospitals to build custom integrations—costing between $20,000 and $100,000.

Avoided $20K–$100K per integration by implementing a reusable HL7-DICOM interoperability framework

Our Solution - Enabling Standards-  Based ECG Interoperability

To address the interoperability gap, Dash Technologies implemented a standards-based integration framework that enables the ECG platform to automatically transmit reports to hospital systems using HL7 and DICOM protocols. 
Phase 1

Interoperability Mapping

Dash began by analyzing the ECG report structure generated by the diagnostic platform.

Since the system produced reports in XML format, the team mapped diagnostic data elements to healthcare standards to support HL7 ECG integration and downstream system compatibility.

Key activities included:

  • Analyzing ECG report schema and waveform data
  • Mapping XML report fields to HL7 message structures
  • Designing DICOM-compatible formats for DICOM ECG data transformation

This ensured that ECG reports generated by the system could be translated into formats accepted by hospital IT infrastructure.

Phase 2

Integration Processing Engine

Dash then developed a background processing service responsible for managing ECG report transmission.

This service continuously monitors newly generated ECG reports and automatically initiates the integration workflow.

The engine performs several functions:

  • Detects newly generated ECG reports
  • Parses XML diagnostic data
  • Triggers DICOM ECG data transformation and HL7 message creation
  • Securely transmits reports to hospital systems

This automation eliminates manual workflows and ensures consistent report delivery.

Phase 3

HL7 and DICOM Transformation

A transformation layer was implemented to convert ECG reports into standardized healthcare messaging formats.

The integration framework generates:

  • HL7 messages for Epic EHR integration and other hospital systems
  • DICOM objects for storing diagnostic reports in imaging repositories

This enables ECG data to be automatically interpreted and archived within hospital environments.

Phase 4

Epic & DICOM System Integration

Once the transformation framework was established, Dash enabled seamless communication with hospital systems.

ECG reports generated by the diagnostic platform can now be transmitted to:

  • Epic EHR integration, allowing clinicians to access reports within patient records
  • DICOM servers, enabling long-term archival of diagnostic data

This approach ensures standards-based ECG interoperability, making diagnostic data accessible across the clinical ecosystem.

From isolated ECG reports to real-time clinical visibility —Dash turned data silos into connected care.

The Dash difference

By enabling standards-based interoperability using HL7 and DICOM , the ECG platform evolved from a standalone diagnostic system into an interoperable solution capable of transmitting reports directly to hospital systems such as Epic.
