What Is Mirth In Healthcare
“Open source operating systems, databases, web servers, and system utilities are slowly making inroads into hospital data centers that formerly housed only proprietary technology products. Add another category in which an open source alternative is available: integration engines.” Tim Dotson Inside Healthcare Computing The Mirth Project is an open source healthcare interface engine and interface repository created and professionally supported by WebReach,

Mirth provides standards-based tools to develop, test, and deploy interoperability solutions for healthcare information systems and information exchanges. This article provides an overview of healthcare interface engines. It discusses Mirth and the healthcare and connectivity standards it supports. Lastly, the article compares Mirth to other interface engines.

Introduction to Healthcare Interface Engines Healthcare interface engines, also known as healthcare integration engines, solve the problem of sharing and exchanging data between healthcare applications. Data interchange is a significant problem in healthcare.

  • There are numerous vendors, data providers, and custom applications that need to exchange information using evolving standards.
  • To make things worse, many legacy healthcare applications do not support a standard, yet they are required to intercommunicate with other standards-based applications.
  • Healthcare interface engines connect applications by mapping and transferring data between the applications using standards and data definitions understood natively by each application.

Interface engines have been available for many years and there are many engines available in the market. The cost of proprietary engines range from the low hundreds of dollars to hundreds of thousands of dollars for organization-level licenses. A review of interface engines is available from KLAS, an independent market intelligence research firm.

  • The KLAS Interface Engines Market Review collects data about leading interface engines and ranks them by several criteria.
  • This article will discuss an open source interface engine called Mirth.
  • Even though Mirth is not ranked by the KLAS review, many people in the Mirth community claim Mirth is functionally equivalent to high-end proprietary interface engines.

Introduction to Mirth Mirth is middleware that connects health information systems so they can exchange clinical and administrative data. Mirth is released under the Mozilla Public License v1.1 and is professionally supported by WebReach, a Health information technology (IT) solutions company based in California.

There are many standards in healthcare, with a diverse range of protocols and types of data. There are different health information systems such as labs, pharmacies, clinics, hospitals, and many others. Each of these systems might have different protocols, mismatched versions, and incompatible data. Some systems might actively use HL7, X12, and DICOM images, while others simply have a database to read from or communicate with XML and comma separated values.

Add to that the lack of control administrators have over current and legacy applications, and the healthcare interoperability problem becomes apparent. This is where Mirth steps in as the easy to use and deploy middleware solution. Mirth can lie between any number of health information systems, whether they speak a standard healthcare language or not, and help them communicate.

Mirth is a flexible health IT infrastructure component and can serve many roles. It can provide central integration exchange at a hospital, an information gateway for a clinic or reference lab, or an information exchange for a Health Information Exchange ( HIE ) or Local Health Integration Network ( LHIN ).

It can also act as the integrated interface engine for an electronic health record ( EHR ) or as an extract, transform, and load ( ETL ) tool. By using a point-and-click interface and JavaScript to map data elements, Mirth speeds the development of interfaces for secure exchange of data across formats.

  • For example, one can exchange data from a delimited file to HL7 or vice versa.
  • This ease-of-use reduces barriers to the formation of health information exchanges involving diverse information systems and advances initiatives aimed at improving patient safety and continuity of care.
  • Figure 1 provides a screenshot of this interface.

In this example, Mirth is receiving input from a database and has converted the data to HL7 format: Figure 1: Database Reader Channel – Source Transformer The Mirth Reference Guide provides many more examples and screenshots for using Mirth. Mirth also provides an open framework and repository for creating and sharing Mirth channels, A Mirth channel is an interface that routes, filters, and transforms messages from one source to one or many destinations.

These channels can also be chained together for more complex logic. Sharing channels enables those in the healthcare IT community to benefit from the work of others and eliminates the redundancy inherent in current processes that require each organization to develop the data mappings between systems.

An ideology that focuses on sharing and openness is a major leap forward over the closed and proprietary system the healthcare IT community is used to. This community-based, open approach has been demonstrated to speed innovation in other industries and is now available for the first time in healthcare.

Supported Healthcare and Connectivity Standards Mirth supports healthcare standards such as HL7 for the exchange, integration, sharing and retrieval of electronic health information, DICOM for medical imaging, X12 for the transmission of electronic data, NCPDP for pharmacy data, and XML to facilitate information flow for lab results, medical records, radiology data, transcription information, claims data, and so on.

These standards are further described below. Supported healthcare data standards include: HL7 v2 & v3: Health Level 7 is a widely recognized standard for exchanging healthcare information between healthcare applications and systems. More information can be found here. DICOM: Digital Imaging and Communications in Medicine is a standard that supports messaging and imaging between imaging devices and systems.

More information can be found at http://medical.nema.org/, NCPDP: Mirth supports the National Council for Prescription Drug Programs Script standard which facilitates ePrescribing ( http://en.wikipedia.org/wiki/Eprescribing ). More information can be found here.

Project Comparison Although Mirth is in the very specific domain of open source software (OSS) integration engines that focus on healthcare, there are other OSS integration engines in the same domain. JEngine is another open source enterprise integration engine implemented in Java.

JEngine is deployed inside the JBoss application server, and uses XML configuration files and BeanShell in order to set up interfaces. The latest version of JEngine was released more than 5 years ago, in October of 2003. ChainBuilder is an open source integration engine that uses its own Enterprise Service Bus (ESB).

The ChainBuilder ESB components are Java Business Integration (JBI) compliant, supporting common protocols and the parsing of healthcare standards like HL7 and X12. Interfaces are configured using plugins for the Eclipse integrated development environment (IDE), and it might take some previous development experience to get started.

  • XAware is a Spring based integration engine that was recently open sourced.
  • Like ChainBuilder, XAware uses the Eclipse IDE for creating and deploying interfaces through plugins.
  • Though XAware does not specifically target healthcare, it is a generic integration engine that supports many endpoints and protocols, including X12.

Mirth separates itself from other competitors and open source tools by its ease of use. Mirth can be downloaded, installed, and configured to have a custom interface running in a matter of minutes. After a few simple steps, any system can be configured to receive and/or send HL7 and many other healthcare standards.

Although Mirth is open source, it is widely recognized to be feature comparable to commercial healthcare integration tools. Mirth now has over 50,000 downloads and is seen by many as one of the top competitors in the healthcare integration engine space. Conclusion The combination of open source and a standards-based approach to healthcare interoperability has resonated with the global health information technology community.

Healthcare executives welcome Mirth to their tooling portfolio because it is feature-comparable to commercial tools, accelerates interface development, and is professionally supported. Consequently, Mirth has been adopted by numerous hospitals, clinics, information exchanges, integrators, and application developers.

Is Mirth Java or Javascript?

JavaScript in Mirth Connection I feel the qestion is very broad. I try my best to make u understand shortly. Yes mirth uses javascript. It is made with Rhino engine. Which also means you can write your program in JAVA as well as Javascript. Tool provides very effective functionality to connect from one end system to another, parse incoming data, receives acknowledgement from the end system etc.

  1. We need to use javascript for other interoperability/storing/retriving functionality.
  2. The Javascript used is not unobtrusive javascript or framework driven javascript.
  3. You will be given much liberty to write functions, that can be used in multiple channels, or for single channel and execute whatever you do in Java the same can be implemented via Javascript inside Mirth as well.

Here are some of tutorials to start learning how to use javascript and Mirth Tool: http://www.mirthcorp.com/community/wiki/display/mirth/Mirth+for+Dummies http://www.mirthcorp.com/community/wiki/pages/viewpage.action?pageId=4358193 https://amarnathks.wordpress.com/tag/mirth-beginner-tutorial/ http://wiki.patesco.ca/doku.php?id=hl7:mirth:tutorial https://hl7engine.wordpress.com/category/mirth-tool/ : JavaScript in Mirth Connection

Introduction to Healthcare Interface Engines Healthcare interface engines, also known as healthcare integration engines, solve the problem of sharing and exchanging data between healthcare applications. Data interchange is a significant problem in healthcare.

There are numerous vendors, data providers, and custom applications that need to exchange information using evolving standards. To make things worse, many legacy healthcare applications do not support a standard, yet they are required to intercommunicate with other standards-based applications. Healthcare interface engines connect applications by mapping and transferring data between the applications using standards and data definitions understood natively by each application.

Interface engines have been available for many years and there are many engines available in the market. The cost of proprietary engines range from the low hundreds of dollars to hundreds of thousands of dollars for organization-level licenses. A review of interface engines is available from KLAS, an independent market intelligence research firm.

  1. The KLAS Interface Engines Market Review collects data about leading interface engines and ranks them by several criteria.
  2. This article will discuss an open source interface engine called Mirth.
  3. Even though Mirth is not ranked by the KLAS review, many people in the Mirth community claim Mirth is functionally equivalent to high-end proprietary interface engines.

Introduction to Mirth Mirth is middleware that connects health information systems so they can exchange clinical and administrative data. Mirth is released under the Mozilla Public License v1.1 and is professionally supported by WebReach, a Health information technology (IT) solutions company based in California.

  1. There are many standards in healthcare, with a diverse range of protocols and types of data.
  2. There are different health information systems such as labs, pharmacies, clinics, hospitals, and many others.
  3. Each of these systems might have different protocols, mismatched versions, and incompatible data.
  4. Some systems might actively use HL7, X12, and DICOM images, while others simply have a database to read from or communicate with XML and comma separated values.

Add to that the lack of control administrators have over current and legacy applications, and the healthcare interoperability problem becomes apparent. This is where Mirth steps in as the easy to use and deploy middleware solution. Mirth can lie between any number of health information systems, whether they speak a standard healthcare language or not, and help them communicate.

Mirth is a flexible health IT infrastructure component and can serve many roles. It can provide central integration exchange at a hospital, an information gateway for a clinic or reference lab, or an information exchange for a Health Information Exchange ( HIE ) or Local Health Integration Network ( LHIN ).

It can also act as the integrated interface engine for an electronic health record ( EHR ) or as an extract, transform, and load ( ETL ) tool. By using a point-and-click interface and JavaScript to map data elements, Mirth speeds the development of interfaces for secure exchange of data across formats.

  • For example, one can exchange data from a delimited file to HL7 or vice versa.
  • This ease-of-use reduces barriers to the formation of health information exchanges involving diverse information systems and advances initiatives aimed at improving patient safety and continuity of care.
  • Figure 1 provides a screenshot of this interface.

In this example, Mirth is receiving input from a database and has converted the data to HL7 format: Figure 1: Database Reader Channel – Source Transformer The Mirth Reference Guide provides many more examples and screenshots for using Mirth. Mirth also provides an open framework and repository for creating and sharing Mirth channels, A Mirth channel is an interface that routes, filters, and transforms messages from one source to one or many destinations.

These channels can also be chained together for more complex logic. Sharing channels enables those in the healthcare IT community to benefit from the work of others and eliminates the redundancy inherent in current processes that require each organization to develop the data mappings between systems.

An ideology that focuses on sharing and openness is a major leap forward over the closed and proprietary system the healthcare IT community is used to. This community-based, open approach has been demonstrated to speed innovation in other industries and is now available for the first time in healthcare.

Supported Healthcare and Connectivity Standards Mirth supports healthcare standards such as HL7 for the exchange, integration, sharing and retrieval of electronic health information, DICOM for medical imaging, X12 for the transmission of electronic data, NCPDP for pharmacy data, and XML to facilitate information flow for lab results, medical records, radiology data, transcription information, claims data, and so on.

These standards are further described below. Supported healthcare data standards include: HL7 v2 & v3: Health Level 7 is a widely recognized standard for exchanging healthcare information between healthcare applications and systems. More information can be found here. DICOM: Digital Imaging and Communications in Medicine is a standard that supports messaging and imaging between imaging devices and systems.

More information can be found at http://medical.nema.org/, NCPDP: Mirth supports the National Council for Prescription Drug Programs Script standard which facilitates ePrescribing ( http://en.wikipedia.org/wiki/Eprescribing ). More information can be found here.

Project Comparison Although Mirth is in the very specific domain of open source software (OSS) integration engines that focus on healthcare, there are other OSS integration engines in the same domain. JEngine is another open source enterprise integration engine implemented in Java.

JEngine is deployed inside the JBoss application server, and uses XML configuration files and BeanShell in order to set up interfaces. The latest version of JEngine was released more than 5 years ago, in October of 2003. ChainBuilder is an open source integration engine that uses its own Enterprise Service Bus (ESB).

The ChainBuilder ESB components are Java Business Integration (JBI) compliant, supporting common protocols and the parsing of healthcare standards like HL7 and X12. Interfaces are configured using plugins for the Eclipse integrated development environment (IDE), and it might take some previous development experience to get started.

  • XAware is a Spring based integration engine that was recently open sourced.
  • Like ChainBuilder, XAware uses the Eclipse IDE for creating and deploying interfaces through plugins.
  • Though XAware does not specifically target healthcare, it is a generic integration engine that supports many endpoints and protocols, including X12.

Mirth separates itself from other competitors and open source tools by its ease of use. Mirth can be downloaded, installed, and configured to have a custom interface running in a matter of minutes. After a few simple steps, any system can be configured to receive and/or send HL7 and many other healthcare standards.

  1. Although Mirth is open source, it is widely recognized to be feature comparable to commercial healthcare integration tools.
  2. Mirth now has over 50,000 downloads and is seen by many as one of the top competitors in the healthcare integration engine space.
  3. Conclusion The combination of open source and a standards-based approach to healthcare interoperability has resonated with the global health information technology community.

Healthcare executives welcome Mirth to their tooling portfolio because it is feature-comparable to commercial tools, accelerates interface development, and is professionally supported. Consequently, Mirth has been adopted by numerous hospitals, clinics, information exchanges, integrators, and application developers.

Why is Mirth Connect the number 1 preferred interface engine NextGen Connect or Mirth connect is a cross-platform interface engine used in the that enables the using bi-directional sending of many types of messages. The primary use of this interface engine is in healthcare. What Is Mirth In Healthcare On September 9th, 2013 Mirth Corporation announced they were acquired by, Mirth Connect has since been rebranded as NextGen Connect. Mirth Connect was born out of a desire to develop an internal integration engine. At first, the Mirth® R&D team only wanted to figure out how to parse HL7 messages.

  • Gerald Bortis, vice president of R&D, said he tried to get access to competitive demo tools, but there was no way to quickly get a demo version to play with.
  • Along with Jacob Brauer, now the director of software engineering for R&D, they decided to build a demo version that solved R&D’s needs.
  • After developing their own HL7 message parser and router, they decided to turn their project into an open source program so any developer working in health IT could use it.

What HL7 means?

Active Learning of the HL7 Medical Standard Department of Electrical Engineering, École de Technologie Supérieure, 1100 Notre-Dame West, Montreal, QC H3C 1K3 Canada Find articles by © The Author(s) 2018 Open Access This article is distributed under the terms of the Creative Commons Attribution 4.0 International License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

Health Level Seven (HL7®) is a standard for exchanging information between medical information systems. It is widely deployed and covers the exchange of information in several functional domains. It is very important and crucial to achieve interoperability in healthcare. HL7 competences are needed by all professionals touching information technology in healthcare.

However, learning the standard has always been long and difficult due to its large breadth as well as to large and complex documentation. In this paper, we describe an innovative active learning approach based on solving problems from real clinical scenarios to learn the HL7 standard, quickly.

We present the clinical scenarios used to achieve learning. For each scenario, we describe and discuss the learning objectives, clinical problem, clinical data, scaffolding introduction to the standard, software used, and the work required from the students. We present and discuss the results obtained by implementing the proposed approach during several semesters as part of a graduate course.

Our proposed method has proven that HL7 can be learned quickly. We were successful in enabling students of different backgrounds to gain confidence and get familiar with a complex healthcare standard without the need for any software development skill.

Eywords: Active learning, Healthcare, Medical informatics, HL7 standard, Problem based, Learning, Interoperability The Health Level Seven (HL7®) standard is very important to achieve interoperability in healthcare. It is widely used for communicating medical information between various information systems ; it is therefore a cornerstone to implement the Electronic Health Record (EHR).

EHR improves healthcare decisions by allowing access to the patient’s relevant clinical information at the decision-making point. EHR is a distributed system that results from the interactions and cooperation of various independent information systems to achieve a specific healthcare process.

Therefore, deploying EHR requires the successful exchange of information between several systems. Without HL7, there is no interoperability and no EHR. Although HL7 is crucial for achieving EHR, learning it has been achieved ad hoc, after long exposure to interoperability problems, sometimes combined with specialized training provided outside of the academic structure.

By introducing HL7 in a graduate course on distributed systems in healthcare, we have faced several problems. These problems are the following: (1) the domain is multidisciplinary, (2) the breadth of required healthcare processes knowledge is large, (3) the standard documentation is huge and formal introductory texts are not available, (4) the students’ background is extremely diversified.

HL7 is at the intersection of healthcare, engineering, and Information Technology (IT). It covers almost all functional domains encountered in healthcare including patient management and administration, order management, and observation reporting. In order to achieve interoperability, many other standards are needed.

Some are not specific to healthcare such as the ones that pertain to security or to indexing. Others are specific to healthcare such as the Digital Imaging and Communication in Medicine (DICOM). All these standards are used in practice. Their cooperation is defined either site-specifically, or according to formal international integration profiles described by the Integration Healthcare Enterprise (IHE),

  • Several versions of the HL7 standard exist.
  • HL7 v2 is largely implemented and deployed in almost every healthcare hospital or clinic.
  • HL7 v3 is adopted by many governments and agencies as a standard required for EHR and is used in many of the IHE integration profiles,
  • HL7 has very recently proposed a new framework, the Fast Healthcare Interoperability Resources (FHIR®), which combines features of HL7 v2 and HL7 v3 with the latest web technologies such as the Representational State Transfer (REST) architecture to facilitate implementation.

All versions co-exist and it is common to have several versions of the standard deployed simultaneously and cooperating at the same institution. HL7 is needed by almost every professional involved with healthcare processes. Knowing HL7 is needed by engineers not only to design and implement interoperable medical systems but also to maintain them.

  1. It is needed by clinicians and IT specialists to implement healthcare workflows.
  2. Administrators need HL7 to manage the purchase processes of such systems.
  3. Companies need HL7 to develop, test, and deploy healthcare systems.
  4. It is needed by hospitals and clinics to purchase their clinical applications and to manage and maintain them.

HL7 is also needed by governmental agencies so they can provide specifications and regulations to enable the integration of healthcare information at the regional and national levels. This large range of dependence on HL7 is reflected in the students’ background.

  • Their prior experience and training include engineering, IT, medical technologies, biology, nursing, and medical practice.
  • All rely on HL7 to accomplish a specific purpose whether system design or writing a request for purchase.
  • Some students have extensive programming skills while others have limited computer skills.

All have the same objective to achieve better healthcare and mastering HL7 is a must for all of them. We are interested in enabling students with diversified backgrounds to quickly learn and use HL7. The standard documentation is written to be a complete reference, but not necessarily to be easy to read or to be used for quick learning.

  1. The HL7 v3 documentation is structured and constructed to be mainly navigated using a browser.
  2. The message names as well as the names of the other artifacts are very hard to be remembered by a human.
  3. The presence of hyperlinks allows non-sequential navigation; however, it is very common to get lost especially for a novice reader.

Other resources and documentations, such as the primer book, concentrate on the information model along with some general concepts. They are not very helpful for quickly implementing something useful with the standard, such as exchanging information.

  1. On the other hand, active learning is increasingly attracting interest as it enhances learning,
  2. Amongst the various active learning strategies, problem-based learning appears to be well adapted to help us achieve our pedagogical goals in a short time, mitigating the difficulties discussed above.
  3. In this paper, we describe a problem-based strategy to learn the HL7 standard.

Following the method of to guide the design of the learning activities, we present and discuss the problem definition, and the support provided to the students. In the next section, we present our method: problem definition in terms of learning objectives, clinical scenarios, and required work as well as resources to support the learning activities such as clinical data, scaffolding documentation to navigate the standard text, and validation software.

  1. The software used by the students was developed specifically to help those with no software development experience, get familiar and use HL7 v2 and v3 in a short time.
  2. Results from our experience teaching both versions of the HL7 standard are presented and discussed in the “” section.
  3. We also describe students’ interests and results.

First, we defined the problems that enable achieving the learning outcomes and engage the students in activities presenting challenges from the real world. We defined two complex problems articulated around clinical scenarios. The first scenario is taken from a radiology environment and is used to learn HL7 v2.

The second scenario is taken from an EHR environment and is used to learn HL7 v3. In addition to the main learning outcome, which is getting familiar with the HL7 standard, we articulated the problems to achieve secondary larger objectives: (1) introducing interoperability, (2) and getting familiar with EHR workflows.

Second, we developed the support material to enable active learning. Several criteria have guided this development: (1) the learning objectives need to be achieved by students with no programming skills; therefore, we have developed a complete software infrastructure allowing students to concentrate strictly on data and information.

  • 2) Students’ confidence regarding the navigation of the complex and large standard documentation needs to be increased; therefore, we have developed a scaffolding document describing how to read and navigate strictly those parts of the standard needed to successfully solve the problems.
  • This is the opposite of how normally HL7 is presented as we did not cover the complete data model.

(3) Students’ confidence regarding their ability to successfully complete the educational work needs to be increased; therefore, we developed validation software that provided feedback to students and helped them self-assess their work. In the following sub-sections, we present the clinical scenarios.

For each scenario, we describe and discuss (1) the learning objectives, (2) the clinical data provided to the students, (3) the scaffolding introduction to the HL7 standard, (4) the work required from the students, and (5) the software that was provided to the students to help them achieve their work.

A typical scheduled radiology image acquisition is performed upon receiving an order from an order placer system. The order message is an HL7 Order Message (ORM) that communicates the patient demographics and the ordering physician information, as well as information about the imaging procedure to be performed.

The ORM is received by the Radiology Information System (RIS) that generates a modality work item on its worklist. When the imaging acquisition equipment is integrated with the RIS, a modality worklist query, using the DICOM standard, is sent from the acquisition equipment to the RIS in order to obtain a list of imaging acquisition steps to perform.

The human operator at the acquisition equipment console typically chooses one item from the list and performs the imaging acquisition on the patient. It results in the generation of a DICOM image whose patient’s demographic and procedure information are automatically copied from the modality worklist fields into the DICOM image header.

  • The worklist fields are initially copied from the received ORM.
  • The mapping between the ORM fields and the image DICOM header fields are detailed in the IHE technical framework,
  • After the acquisition is completed, the radiologist interprets the image and generates a diagnostic report that may be communicated to a third-party system by means of an HL7 Observation Result (ORU) message.

In addition to the patient’s demographic and procedure fields, the ORU message contains the impressions and interpretation of the radiologist. The data flow of this simplified radiology process is depicted in Fig. The acquisition step needs the patient’s demographics and procedure information in order to generate an image.

What is HL7 explained?

Health Level-7 (HL7) was created by Health Level Seven International, a non-profit organization dedicated to developing standards for the exchange of electronic health care data. HL7 is a set of international standards used to transfer and share data between various healthcare providers.

  1. More specifically, HL7 helps bridge the gap between health IT applications and makes sharing healthcare data easier and more efficient when compared to older methods.
  2. Most healthcare providers use a variety of applications for everything from billing to keeping up with patient information.
  3. The problem is that communication between these different types of software is hard to achieve, even though they often need to talk to each other.

Another layer of problems arises when two healthcare providers need to share information. HL7 provides several standards and guidelines to help software vendors and healthcare providers store and uniformly move data. This way, applications can use the data without using special software for conversions or needing to send paper copies.
