HL7 integration

Keystone Bi-Directional HL7 interface

The goal of Keystone Medical Technologies is to ensure all systems and applications within a healthcare system work smoothly together for organized, seamless data flow. The first step is to understand your current workflow.

Bi-Directional HLT

The technology used in imaging centers is always evolving and changing. The technology changes affect both the front-end and back-end workflows. The front-end workflows are affected by changing imaging and modality technology advancements while the back-end workflows are affected by advancements in information technology. For example, in the back-end of an imaging center the workflow might resemble the following:

• Schedulers manually enter orders on the radiology information system (RIS) or orders move into the RIS electronically from external referring physicians or hospital systems.
• Those orders flow to various internal systems such as the picture archiving and communication systems (PACS) and a voice recognition (VR) application.
• The images are acquired:
o Modalities query the modality work list manager.
o Once the procedure is completed, images are returned to PACS.
o A radiologist reads the images and dictates the results into a VR application.
o A radiologist self-corrects and approves the reports.
o The reports are distributed to RIS, PACS, Billing and the applicable referring locations.

In an imaging center, clinical data must move to and from multiple systems. Even though the workflow is unique for each imaging center, the need to transfer clinical data is not. The moving of data is where HL7 interfaces can make the most headway towards bridging the gap for interoperability and creating that organized and seamless data flow.

Using an HL7 integration approach to move clinical data between applications helps:

• Optimize information systems
• Reduce errors in multiple, manual entries
• Maximize radiology workflow
• Facilitate growth through an efficient workflow

With greater requirements for RIS-driven workflow and data exchanges with referring physicians, the HL7 Standard plays a prominent role now and into the future for automating workflow.
