Use Case Patient Tanaka has scheduled CT scan at today’s 10:00 am. But Tanaka not arrived at the reception of radiology department, so medical staff cannot start CT scan.Patient Tanaka has scheduled CT scan at today’s 10:00 am.

Discussion If the patients’ whereabouts is accessible and referable, current medical information system could provide more efficient patient management to the users of the system. Recently improved technologies, such as RFID, enables to build the system which can easily shows patient location in a medical facility.If the patients’ whereabouts is accessible and referable, current medical information system could provide more efficient patient management to the users of the system.

PAM (Patient Administration Management), which has already been published in the ITI-Domain, is the one-way function that shares information by receiving one and then passing the same to the pre-designated receiver. There are no managers in the PAM integration profile.PAM (Patient Administration Management), which has already been published in the ITI-Domain, is the one-way function that shares information by receiving one and then passing the same to the pre-designated receiver.

PAM Patient Administration Management (PAM) Integration profile is able to provide current information regarding a patient’s encounter status and location. The Temporary Patient Transfer Tracking Option defines the information exchange needed for tracking a temporary leave/return of a patient from/to a care facility.Patient Administration Management (PAM) Integration profile is able to provide current information regarding a patient’s encounter status and location.

Patient Encounter Manager always knows where the patient is and can answer the patient location to respond a query.PEQ has three actors (Patient Encounter Source, Patient Encounter Manager and Patient Encounter Consumer).

Q&A-1Q1) What is the scope of your proposal in terms of application to a single enterprise or across enterprises. We believe the proposal is designed to address across departments within a hospital or similar facility but not for outside the hospital or across enterprises. Can you clarify the scope in this respect? A1) PEQ is used in a single hospital not across enterprises.

Q&A-2Q2) How is the patient management system tracking the location of patients? We believe other systems are expected to feed information into the patient management system. A2) PEQ’s actors consist of (1) Patient Encounter Source, (2) Patient Encounter Manager and (3) Patient Encounter Consumer. Patient Encounter Manager updates the patient location by receiving the location transaction. Other systems (such as ADT, OP, OF, Modality) feed patient location to PEQ manager.

Q&A-5Q3) What level of detail are you expecting for the location of a patient? For example, we could manage location by department or at a finer level detail like specific room or specific spot within a room or hall. Use of RFID would provide more detailed information like specific location in hall or room, are you expecting to support this level of detail? A3) The detail of location depends on the purpose of a user. By our preliminary discussion the location needs 2 levels, for example department and room. We expect future analysis of location.

Q&A-4Q4) Are you expecting the system to understand the differences between a patient entering a room or department, vs. a patient having left the room or department. Is this level of detail required or expected. A4) Ideal Patient Encounter Source detects the three events of (1) entering, (2) existing and (3) leaving of a location. Patient Encounter Source optionally transmits the information of entering, existing and leaving.

Q&A-5Q5) Is this expected to interact with the systems that manage patient transport within the hospital and if yes, how. A5)No.

Q&A-6Q6) Are you interested in interfacing with a physical location patient management system. A6) Yes. In Japan patients often have multiple reservations of outpatient consultation ( ex. Internal medicine, Ophthalmology and Orthopedics) in a day. Perhaps physicians want to know the location of patient.

Q&A-7Q7) What are the encounter management assumptions? For example, when an encounter is started you know where patient is but when an encounter is completed the patient location of the patient becomes unknown. What are the assumptions on the location of a patient in between encounters. A7) We believe that some assumptions are necessary for manager actor. At least one of the events (entering, existing and leaving) must be reported. For example, physician of the outpatient clinic wants to know the patient’s entering to waiting area. If there is no Patient Encounter Source in the waiting area, the hospital reception will transmit information and PEQ consumer will suppose that the patient will be in the waiting room. This assumption will depend upon the clinical usage.
