1. UDI Key Features: Medical Device Integration
Hi, I’m Sam Share
Multiple areas of Medical Device Integration
Expand the capabilities IHE Patient Care Devices Technical Framework using FHIR Resource
Deliverables:
Develop EHR functionality standards and data acquisition for medical device integration
Support consistent implementation of Unique Device Identifiers (UDI) across the enterprise
Benefits:
Improve patient safety (i.e. 8-rights, patient-to-device association) and provide a patient-centric approach to medical device tracking and measurement tracking
Removes clinician responsibility manual data entry of medical device measurements thus improving end-user productivity and satisfaction
Automates flowsheets, vitals, and other procedure documentation for acute and intensive care
Improves the quality of care by capturing additional pertinent information from devices (e.g. reference ranges) to support clinical decisions.

4. Vital Signs Monitoring
SSgt. Sam Share (ret.) is admitted at the VA medical center and requires continuous monitoring of vital signs including oximetry. Dr. Lister orders monitoring for the next 24 hours.
Nurse Nightingale starts the monitoring session by assigning a standard-based vital sign monitor to Sam by scanning the device label and Sam’s wrist band (UDIPID) and her badge (PIDEID). She uses the vendor-provided medical device manager or a VA-provided device gateway to record the devices associated with this procedure and patient.
Once the patient-to-device association is completed any measurements, status information, reference ranges, etc. acquired by the device is exchanged with
Medical Device Integration Adapter – MDIA- persists the measurement in the VistA database. LOINC, SNOMED, UCUM used to convey the measurements.
Throughout the monitoring session, Ms. Nightingale validates the data entered by the integrated device into VistA. The validated results become part of Sam’s legal health record
Requires enhancements to the VistA application (functional requirements)
The CCD includes relevant/pertinent vital signs along with other treatment information 1 2 3 4 5

6. Tracking Implantable, Life-Supporting, or Life- Sustaining Devices
SSgt. Sam Share, a veteran, receives a consult from Dr. Lister at a VA facility to treat his combat-related condition. It requires an implantable device to improve Sam’s health status.
Dr. Lister, VA physician, prescribes an implantable device or tissue based on device type and other criteria (e.g. clinical size) and orders the device (based on device identifier (DI portion of UDI) the procedure (HCPCS)
The VA physician Looks up a suitable device using prosthetic list based on the FDA Global Unique Device Identifier Database (GUDID) or uses the pre-loaded “gold” Master Device Identifier file
By type, model, version, vendor, clinical size
Ms. Martin, a VA clerk reviews the order before forwarding the information from the VA-approved distributor and obtains the device required for SSgt. Sam.
A procedure is scheduled for SSgt. Sam, the device is implanted by Dr. Wilson and the UDI is scanned by the designated nurse into VistA. The UDI is associated with the patient and available to community providers in the “Patient Device List” of a CCD If a recall is initiated, the manufacturer notifies VA to inform Sam and other patients using the same type of device in the affected production. 2 1 3 4 5 6 7

8. “Smart” Infusion Pump Programming (Bedside Computer Aided Medication Administration)1
SSgt. Sam Share (ret.) is admitted at the VA medical center and requires medication administered intravenously using a “smart” pump . If used properly, “smart” pump features help prevent I.V. medication errors and reduce patient harm. Dr. Lister orders the drug , dose, route, time/frequency.
The patient, medication, dose, route, time/frequency is sent to the infusion pump gateway.
Nurse Nightingale starts the IV drug administration by assigning a “smart” pump to Sam by scanning the device UDI and Sam’s wrist band and her badge (UDIPID EID) she establishes the patient, device, and operator of the device (EHR may verify it…)
Once the patient-to-device association is completed , the pump gateway is able to associate the ordered medication with the pump assigned to Sam.
Once the Ms. Nightingale validates the “5 rights” the device will send events and other administration information to the patient’s record.
Medical Device Integration Adapter – MDIA- persists the information in the VistA database
Throughout the IV session, Ms. Nightingale validates the data entered by the integrated device into VistA. The validated results become part of Sam’s legal health record.
Requires enhancements to the VistA application to record documentation and validate reason and response to the medication 2 3 4 5 6

10. Bed-side Montoring 1
SSgt. Sam Share (ret.) is recovering from surgery in the step down unit and his vitals are monitored and he is receiving several IV medications.
Nurse Nightingale starts bya ssigning a “smart” pump to Sam by scanning the device UDI and Sam’s wrist band and her badge (UDIs+BedPID EID) she establishes the patient, device, and operator of the device (device security).
Once the patient-to-device association is completed , the device data is send to VistA and assigned to Sam.
Throughout the IV session, Ms. Nightingale validates the data entered by the integrated device into VistA. The validated results become part of Sam’s legal health record.
Requires enhancements to the VistA application to record documentation and validate reason and response to the medication 2 3 4 5 6
