1. Patient Encounter Tracking Query (PEQ) Profile Proposal for IHE International IT Infrastructure Technical Committee Last update: 23/Apr/2012

2. IT Infrastructure Planning Committee What is PEQ profile for ? The Patient Encounter Tracking Query (PEQ) Integration Profile is the integration profile in order to find the location of patient in a hospital.The Patient Encounter Tracking Query (PEQ) Integration Profile is the integration profile in order to find the location of patient in a hospital.

3. IT Infrastructure Planning Committee Backgrounds (in Japan) Single EMR/CPOE covers whole department in a hospital. Patients are moving between multiple departments in a hospital. Reservation time slot is flexible, and technicians manage patients in the slot. (5-15 min per CT exam, 5-15 min per 1 consultation), Therefore, sometimes the patient does not appear on time and medical workers need to find the location of the patient.

5. IT Infrastructure Planning Committee Difference between PEQ and PAM/PDQ PAM(Patient Administration Management) Patient Demographics Supplier Patient Demographics Consumer Patient Encounter Supplier Patient Encounter Consumer Patient Identity Management [ITI-30] Patient Encounter Management [ITI-31] ~ Difference between PAM and PEQ ~ PAM has a capability to notify the patient location, but it does not archive locations of patient. PEQ Manager archives the locations of patient and can be queried by Consumer.

7. IT Infrastructure Planning Committee Use Case-1 (Typical) Patient-Tanaka 5. Medical staff starts CT examination of next patient (Patient-Suzuki). 4. Patient-Tanaka’s temporary location is the internal medicine dept. Patient Encounter Manager 1.Encounter Feed 3.Encounter Query/Response Reception staff 2. Where is Patient- Tanaka? Medical staff

8. IT Infrastructure Planning Committee Use Case-2 (RFID) <Department internal medicine - consultation room> Patient -Sato wearing RFID-Tag Patient Encounter Manager 1. Encounter Feed < Department ophthalmology - consultation room > 4. Patient-Sato’s temporary location is the Department internal medicine. Reception staff 2. Where is Patient - Sato? RFID-System 3. Encounter Query /Response

9. IT Infrastructure Planning Committee Open Issues 1) 1)Application to foreign hospital worldwide Need to see the situation in foreign countries. 2) 2)HL7 version Currently based on v2.5. (v3 can be considerable if needed). 3) 3)Difference between PAM

10. IT Infrastructure Planning Committee Closed Issues 1) 1)Assumption of location information: Assumptions of location information can be implemented on actors in PEQ when a location of patient A is undefined (e.g When patient A left location-A one hour ago and not detected at any place, Patient Encounter Manager or Consumer may be able to assume patient A is waiting at department-X). In this version, we do not consider such assumptions.
