This setting provides administrators the ability to prevent the Medical Records Chart processor from performing a chart move event (for example, moving a chart from one MRN to a different MRN), while running Update Only or Create or Update modes. With this setting, administrators can fine tune their system to only allow explicit chart move requests to perform a move operation.
There are two options for moving charts: explicit and implicit.
-
Explicit chart moves require that the Medical Records Chart processor to be configured in Merge mode, and that the HL7 message contains the same Chart ID value in the PID and MRG segments.
-
Implicit chart moves provides the ability to move a chart from one MRN to another without flagging the message as a merge request. Essentially, any update request can be interpreted as a move request if the message's target MRN identifier differs from what can already be found in the database for the existing chart record.
In systems that were upgraded from previous versions of OnBase prior to the OnBase EP5 release, the Allow Implicit Chart Movesoption is enabled by default in the HL7 Settings dialog box. For new OnBase systems initialized on OnBase EP5 or later, this setting is disabled by default.
The best practice is to use explicit chart moves (Allow Implicit Chart Moves check box is disabled). This requires the sending HL7 system to provide the merge chart identifier in an MRG segment. The OnBase HL7 Message Templates also need to be updated to add the MRG segment, and the chart identifier should be set as the Merge Source Identifier.
