HL7 Monitoring: Interface Analytics

Today, nearly every healthcare organization relies on the HL7 messaging standard to exchange information between systems and applications. For this reason, each HL7 message is a critical link in healthcare workflows. If HL7 messages are not delivered or generate errors, then patient admission information, billing details, laboratory results, and other important data cannot be passed from one system to another.

Traditional methods of monitoring HL7 interfaces are limited in terms of functionality. HL7 operations teams must rely on inconsistent server logs and basic dashboards from interface engines to monitor the health and performance of HL7 communications. As a result of this piecemeal approach, these teams often do not know of an issue until they receive complaints from users.

Real-Time Visibility for All HL7 Interfaces

The ExtraHop platform analyzes wire data to automatically discover and classify all active sending and receiving interfaces. This non-invasive approach offers an elegant and quick way to gain holistic, vendor-agnostic visibility into all HL7 communications in an environment, unlike the limited visibility provided by discrete interface engines or interface logging.

HL7 Analytics for Business Intelligence and Clinical Informatics

Because of the flexibile nature of the HL7 standard, HL7 messages carry a tremendously rich trove of operational data. The ExtraHop platform can extract, analyze, and visualize any data field contained within an HL7 message in real time, from message IDs to valuable operational information such as admission time and symptoms. Through ExtraHop's Open Data Stream, these events and metrics can be streamed in real time to a non-proprietary datastore for correlation with other data sets and multidimensional analysis.

Healthcare IT and business leaders can now proactively discover and map HL7 communications across interfaces, analyze the performance and effectiveness of clinical workflows, and derive a wide range of valuable operational and business insights.

Troubleshoot HL7 Interface Problems Faster

With the ExtraHop platform, interface teams can start with the summary dashboard that provides an auto-discovered list of all the active sending and receiving interfaces with corresponding activity metrics. From there, you can drill down to the performance of each individual interface to get relevant insight to help with troubleshooting:

  • Counts for each message type and acknowledgement, including accepts, rejects, and errors
  • Errors sorted by application and message type, including message IDs and error details contained within the HL7 message
  • Round-trip time and processing time for HL7 messages
  • Tracking for duplicate messages

Dynamic Mapping of HL7 Interfaces

Operations teams and HL7 analysts can use the ExtraHop platform to easily keep track of and report on HL7 activity. ExtraHop automatically maps activity between all sending and receiving HL7 interfaces, as well as the applications dependent on those interface connections, all in real time.

Early-Warning Alerts for HL7 Interface Performance

Interface failures and performance issues can impact workflows and the quality of care provided to patients. With intelligent trend-based alerting, the ExtraHop platform equips interface teams to fix issues early. For example, if an interface is modified, and that modification causes a spike in errors, ExtraHop would alert on that. In addition, the ExtraHop platform can alert on the success or failure of high-priority orders, including Stat, ASAP, and others.


ExtraHop is a force multiplier for stretched healthcare IT teams, equipping them with real-time insights that they did not have before. The new HL7 analytics capabilities open up tremendous new possibilities in terms of HL7 efficacy and operational intelligence.
