Integration Engine 50
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.
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.
An integration engine (and seriously, let’s stop calling it an interface engine. it does so much more) is an essential piece of healthcare’s technology infrastructure.
Today, during this unprecedented global pandemic we need a highly reliable solution to integrate our data seamlessly.
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.
This section describes the most common HL7 transport method used to send HL7 messages, called the Lower Layer Protocol (LLP). A less common HL7 transport called the Hybrid Lower Layer Protocol (HLLP) is also briefly discussed. Although HL7 messages are sent via a variety of TCP/IP transports, including FTP, SOAP and SMTP, LLP is the most common method.
n an HL7 message, each segment of the message contains one specific category of health information, such as patient information or patient visit data. The name of each segment in the message is specified by the first field of the segment, which is always three characters long.
What is data accessibility in healthcare? Data accessibility plays an important role in delivering high quality patient care as it provides clinicians with immediate access to patient records, including medical history, test results and relevant information provided by other clinicians. Access to the right amount of data at the right time improves clinical workflow by […]
