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.

What Are Common HL7 Transport Methods?

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.

Inside HL7 Messages: What are HL7 Segments?

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.
