Patient Location Tracking

The Patient Location Tracking (PLT) Integration Profile provides an integration solution to find the physical location (PL) of patients.


The Patient Location Tracking (PLT) Integration Profile provides an integration solution to find the physical location (PL) of patients. A physical location can be mapped to the service delivery location (SDL). An implementation may support SDL with this profile, e.g., using an appropriate code system of locations which relates PL to SDL. A PL may be shared by more than one SDL. It is up to an implementation to define their relationship if it decides to support SDL with this profile. IHE does not specify a mapping of PL to SDL.


Quickly locate patients with a simple query.


The Patient Location Tracking (PLT) Integration Profile supports collecting the patient location information in a facility, and providing his/her recently recognized location to other systems. PLT covers patient location tracking inside single facilities, not between two or more facilities.

There is no systemized mechanism that records the latest location of the patients in a hospital due to the lack of a standardized method to collect it. The Patient Location Tracking (PLT) Integration Profile standardizes the transactions, records patients' locations, and provides the latest information upon request from external subsystems.

Patient locations are recognized by Patient Location Tracking Suppliers, and received/managed by Patient Location Tracking Managers. Transaction [ITI-76] is used for a Patient Location Tracking Feed. Requests for a patient location are sent from Patient Location Tracking Consumers to Patient Location Tracking Managers using Patient Location Tracking Query [ITI-77].

Systems Affected

Systems that track location and have a need to share it with easy queries. Systems that need to discover patient location with queries.
