Mirth Connect Healthcare Integration Engine
Mirth Connect (NextGen Connect) is the world's most widely deployed open-source healthcare integration engine. We design, build, and manage Mirth Connect channels that seamlessly exchange HL7 v2, FHIR, X12 EDI, DICOM, and proprietary format messages between any combination of healthcare systems — reliably, securely, and at scale.

Seamless, Integrated, and Patient-Centered Data Exchange
Modern healthcare delivery requires real-time data exchange between dozens of systems — EMR, lab, pharmacy, imaging, billing, population health, and patient engagement. Mirth Connect is the integration middleware that makes it possible without building point-to-point integrations for every pair of systems.
HL7 Message Processing
Ingest, parse, transform, filter, and route HL7 v2.x messages (ADT, ORM, ORU, SIU, MDM, DFT) with custom JavaScript and Mirth transformers — handling the messiest real-world HL7 feeds from legacy hospital systems.
Healthcare Interoperability
Connect disparate systems — EMR, LIMS, pharmacy, PACS, population health, HIE, and insurance — through a centralized integration hub that eliminates the n² problem of point-to-point interfaces.
Mirth Connect Administration
Full-lifecycle Mirth Connect services: installation, cluster configuration, channel development, monitoring dashboards, error alerting, certificate management, upgrade planning, and tier-2/3 operational support.
Mirth Connect Capabilities We Deploy
From simple HL7 feed transformations to complex multi-system integration hubs, Mirth Connect handles it all.
Why Healthcare IT Teams Choose Woltrio for Mirth
Mirth Connect expertise is rare. Our engineers have built hundreds of integration channels across every major EHR platform and clinical system in production environments.
Deep HL7 & FHIR Expertise
We understand HL7 v2's quirks — Z-segments, non-standard separators, legacy vendor deviations — and FHIR's nuances across R4, STU3, and DSTU2. We fix the edge cases that break other integration teams.
Production-Proven Channels
Our channels are built for 24/7 production reliability with proper error handling, dead-letter queues, retry logic, and message reprocessing capabilities — not just demo-quality proof-of-concepts.
Ongoing Operational Support
We offer 24/7 Mirth Connect operational support with defined SLAs — including on-call escalation for channel outages that affect patient care workflows.

Frequently
Asked Questions
Seeking basic information? Our FAQ section is a ready reckoner with precise answers to the most probable queries.
What is Mirth Connect?
Mirth Connect (originally developed by Mirth Corporation, now marketed as NextGen Connect) is an open-source healthcare integration engine — also known as an interface engine or middleware — that processes, transforms, and routes healthcare messages between clinical systems. It supports all major healthcare messaging standards including HL7 v2, HL7 FHIR, X12 EDI, DICOM, and ASTM. Mirth Connect operates on a channel-based architecture where each channel defines an inbound listener, a set of transformation rules, and one or more outbound destinations.
Who uses Mirth Connect?
Mirth Connect is used by hospitals, health systems, ambulatory care networks, clinical laboratories, health information exchanges (HIEs), health insurance companies, digital health vendors, and healthcare IT integrators worldwide. It is particularly popular for connecting Epic, Cerner, Meditech, Allscripts, and other major EHRs to laboratory, pharmacy, imaging, billing, and population health systems. With over 10,000 production deployments globally, it is the most widely used open-source healthcare integration engine.
What is the difference between Mirth Connect and Mirth Enterprise?
The open-source Mirth Connect (NextGen Connect Community Edition) is free to use and includes all core integration capabilities. NextGen Connect Enterprise (formerly Mirth Fully Managed) adds enterprise features including enhanced monitoring dashboards, clustering support, technical support SLAs, FIPS compliance, advanced audit logging, and managed cloud hosting. For organizations with high message volumes, strict uptime requirements, or limited internal IT resources, the Enterprise edition or a managed service from a Mirth Connect partner like Woltrio is typically worth the investment.
Can Mirth Connect handle FHIR?
Yes. Mirth Connect supports FHIR through its HTTP Listener/Sender connectors and the JavaScript transformer engine. Channels can receive FHIR REST API calls, parse FHIR resource bundles, transform them into other formats (HL7 v2, database records, flat files), and route them to target systems. Conversely, Mirth can receive HL7 v2 feeds and produce FHIR resources as output. For complex FHIR workflows, we often pair Mirth Connect with a FHIR server (HAPI FHIR, Smile CDR, Azure API for FHIR) for persistent resource storage.
How do you monitor Mirth Connect in production?
We implement a multi-layer Mirth monitoring stack: (1) Mirth's built-in channel dashboard for per-channel message counts, error rates, and status; (2) custom alerting channels that fire on channel errors, queue backlog thresholds, or processing latency breaches — sending alerts via PagerDuty, Opsgenie, Slack, or email; (3) external APM tools (Datadog, New Relic, Prometheus + Grafana) for JVM heap, CPU, database connection pool, and network metrics; (4) log aggregation in CloudWatch, ELK Stack, or Splunk for message-level audit trails.
Is Mirth Connect free to use?
The Mirth Connect Community Edition (now NextGen Connect Community Edition) is open-source and free to download and use under the Mozilla Public License. There are no per-message or per-channel licensing fees. However, organizations typically incur costs for server infrastructure, professional services (channel development, integration design), and support. For production deployments, most organizations budget for either an enterprise support agreement with NextGen Healthcare or a managed services arrangement with a Mirth Connect integration partner.
