1. Interoperability 101 Bridget A. Moorman, CCE Technical Manager Industry Advisory Board Renewing Health The Continua Alliance

2. Overview What is Interoperability Why be Interoperable Interoperable Healthcare Interoperability for Procurers Standards at Interfaces Example Environments OSI 7 Layer Example PAN, LAN, WAN, HRN Interfaces Procurement Language Market of Interoperable Products Summary

3. What is Interoperability? Interoperability - the ability of a system or a product to work with other systems or products without special effort on the part of the customer Two approaches: –By adhering to published interface standards –By making use of a "broker" of services that can convert one product's interface into another product's interface "on the fly"

4. www.continuaaliance.org Why be interoperable?* Empower individuals and patients to better manage their health by providing them with information regarding their fitness and health through personal medical devices and services. Allow loved ones and professional care givers to more accurately monitor and coach chronic disease patients and elderly individuals living independently. Enable medical and fitness device manufacturers to rapidly develop interoperable devices and services using industry developed connectivity standards. Enable health care providers to offer better quality care through personalized health solutions assembled from a rich marketplace of interoperable health care devices and services. * Per Continua Health Alliance

5. Interoperable Healthcare* ….transmit their vital signs - blood pressure, heart rate, oxygen saturation, glucose levels, temperature, weight, respiration - seamlessly from home to their health professional, and get real- time feedback on their condition ….personal health and medical devices must be fully interoperable with each other and with other information sources; because broad interoperability has yet to be achieved, it is an emerging priority for health systems and for the medical and information technology industries * Per Continua Health Alliance

6. Interoperability for Procurers Meet the needs of your customers –Patients –Clinicians –Administration –Insurance companies –Government Allow for best of breed acquisition Drive market development towards standards based interoperability –Goal to drive down long-term costs –Lessen infrastructure replacement costs –Can allow heterogeneous environment to inter-communicate

7. Standards at Interfaces By adhering to published interface standards –Interfaces Personal or Peripheral Area Network (PAN) Local Area Network (LAN) Wide Area Network (WAN) Health Record Network (HRN) –Interface functions can collapse onto each other depending on environment

8. Standards Promulgation Organizations The Continua Alliance –Focuses on personal health and wellness market Use of IEEE 11073 PHD standards; IHE-PCD-01 for WAN Integrating the Healthcare Environment –Patient Care Devices Domain (IHE-PCD) Use of IEEE 11073 standards; several profiles defined in healthcare environment using medical devices

9. WAN-IF Example I of Environment The Continua Alliance Application Hosting Device PAN Device PAN-IF LAN Device LAN-IF xHRN-IF WAN Device HR Device * 0..1 * * * * * * to service provider to hospital (clinical domain) PAN Device Application Hosting Device PAN Device

10. Example II of Environment IHE-PCD PAN, LAN and WAN interfaces are collapsed into this construct (Integrating the Healthcare Enterprise- Patient Care Devices Domain (IHE- PCD))

11. Example III of Environment The Continua Alliance Standards are Shown at each Interface in this diagram

12. Basic Layers in Interfaces OSI 7 Layer Network Model

13. PAN-LAN Interface Standards - Continua Application Hosting Device PAN Device PAN-IF LAN Device LAN-IF * 0..1 * * PAN Device Application Hosting Device PAN Device

14. WAN Interface Standards – Continua and IHE-PCD WAN-IF Application Hosting Device WAN Device * * to service provider Application Hosting Device

15. HRN Interface Standards – Continua and IHE xHRN-IF WAN Device HR Device * * to hospital (clinical domain)

16. Procurement Language The following interoperability standards are recommended and preferred ….. List by functional interface and OSI layer interface: –Example: Personal Area/Local Area Network; Physical, Data, Network, Transport layers Certification and/or assurance of interoperability in heterogeneous environment (Continua Certification, IHE Conformance Statement)

17. Market of Interoperable Products If market is sparse, still need to include interoperability language to send a message to market –Can become a discriminator in final field of products –Sets tone-communicates your organizations vision for desire of interoperability Can be used in marketing materials to your customers – We are interoperable based on standards

18. Summary Interoperability - the ability of a system or a product to work with other systems or products without special effort on the part of the customer Use of standards based approach Need to include interoperability language to send a message to market –List standards desired in products by functional and network layer interfaces
