Clicking the Filter button from the Patient Request tab displays options for "All locations" and "Filter by current location only." By default, requests for all of your authorized locations (practices) are displayed.
To limit requests to only those from your current location (practice), click Filter by current location only and OK. Doing so can improve performance of the Clinical Messages module.
Note: Changes to this field can also be made from the Preferences module, General section, using the "Patient Request default view" option.
