# Context Management (CCOW) in CPRS

Clinical Context Management (sometimes referred to as "CCOW") is a way for graphical user interface (GUI) applications to synchronize their clinical context based on the Health Level 7 CCOW standard. In simple terms, this means that if CCOW-compliant applications are sharing context and one of the applications changes to a different patient, the other applications will change to that patient as well.

The VA purchased Sentillion's Vergence context management software to work with VistA.

To use the CCOW standard, VistA set up must include these two components:

· a context vault, which is a server on the VA LAN that tracks context for each clinical workstation

· desktop components installed on each workstation that will use CCOW

To allow VistA GUI applications to use context management, the developers must make the necessary changes to HL7 messages for each application to allow synchronization. Current plans call for the following applications to be CCOW-compliant:

· CPRS *

· Health e Vet Desktop (Care Management) *

· Imaging *

· Clinical Procedures

· BCMA (Bar Code Medication Administration)

· Vitals

· FIM (Functional Independence Measure)

· Scheduling

* These applications will be made CCOW compliant first.

CPRS has been made CCOW-compliant and can now synchronize with other VistA CCOW-compliant applications. The first three applications that will be CCOW-compliant are CPRS, Care Management, and Imaging. Care Management provides one example of applications synchronization. If you were in Care Management, which is also CCOW-compliant, and clicked the CPRS Chart link, the CPRS GUI chart would be launched and would bring up the same patient that had focus in Care Management. You can also have two CPRS sessions synchronized. And, of course, you can bring up two different CPRS sessions and not synchronize them, thus allowing you to view two patients' charts at the same time.

The CCOW icon shows whether the current application is linked with others on the desktop.

The above graphic shows the CCOW icon in outlined in red at the far left of the chart.

CPRS enables users to join or break context with other applications. The icon displays whether CPRS is joined in context or not. The following three i cons will display based on the CCOW state:

Linked

Broken

Changing

Note: There are a few cases when you cannot change context, such as when a print dialog is open or when you are trying to open an application from the Tools menu. If you try to change context with unsigned orders or notes, the Problem Changing Clinical Data dialog display and tell the user if there are items that will not be signed. Another dialog display if there is a contextor problem.

If the application is busy doing something and cannot change context, CPRS will display a message such as the one above
