Clinical Document Architecture (CDA): An Overview
Clinical Document Architecture (CDA) is an XML-based standard for encoding clinical documents for easy data exchange.
Integration engines: Build, Buy or Outsource?
Whether you are looking to create a simple HL7 integration with your EHR or exchange more complex data formats, most organizations will eventually find themselves at an inevitable crossroad. Do you build, buy or outsource your integration engine?
3 signs it’s time to migrate to a modern integration engine
Migration to a modern integration engine can be one of the most important decisions you make to help optimize your organization.. Modern integration engines have become more important than ever before, as interoperability has expanded to include a growing number of applications and devices.
Does HL7 software compliance actually exist?
When searching for a medical software vendor, you will find that many providers offer HL7 compliant software. HL7 compliance means that the vendor is adhering to the requirements of the HL7 standard. However, in practice, true HL7 compliance does not exist, as the standardization becomes a challenge depending on the data structure.
Understanding HL7 Segment Grammar Notation
By convention, a standard segment grammar notation is defined to provide a convenient way to indicate the segments that can be included in a particular type of HL7 message.
Many vendors use this segment grammar notation to specify what segments may be included with each type of HL7 message that they send.
Understanding HL7 Delimiter Redefinitions
The HL7 Delimiter Characters shown in the table below lists the default delimiter characters that are normally used in HL7 messages.
An HL7 message can choose to employ HL7 delimiter redefinitions.
If the standard characters are not convenient to use, the HL7 message can use different delimiter characters.
How to replace an interface engine
“The only thing constant in life is change.” – Francoise de la Rochefoucauld 1613 – 1680 Traditionally, upgrading or replacing an interface engine employs the “Test, Switch, Pray” methodology. This means running the new interface engine through a battery of tests to attempt to cover all of the possible use and test cases it may […]
Understanding HL7 Messages: HL7 Composites
Each segment of an HL7 message consists of one or more composites (also known as fields). By default, the | (pipe) character is used to separate one composite from another.
A composite can be a primitive data type (such as a character string or a number), or can contain other composites.
If a composite contains other composites, these sub-composites (or sub-fields) are normally separated by ^ characters.
HL7 Standard: The ACKnowledgment Protocol
An important part of the HL7 standard is the ACKnowledgment protocol.
Every time an application accepts a message and consumes the message data, it is expected to send an ACKnowledgment message back to the sending application.
The sending application is expected to keep on sending a message until it has received an ACK message.
If you do not follow this rule, data may be lost in transmission.
Why HL7 Message Throughput Is a Critical Metric for Interface Engines [White Paper]
The Iguana HL7 interface engine demonstrates high throughput far exceeding the most demanding integration applications.
Iguana® provides you with the necessary tools to develop, test, deploy and monitor your interfaces to integrate your EMR, EHR, HIS, PACS or any other healthcare information systems.
