1 IHE PATIENT CARE DEVICES DOMAIN The Time for Interoperability is NOW!

2 Why Are We Here? Reasons for interoperability Barriers to adoption Momentum moving us forward How IHE is breaking down these barriers Status of IHE-PCD work Future directions of IHE-PCD work

3 Are These Devices Really Available ? 19 products from 15 vendors are available for you to purchase today Device Enterprise Communication (DEC) Point of Care Infusion Verification (PIV) Alarm Communication Management (ACM) Implantable Devices Cardiac Observation (IDCO) Search for IHE-PCD Compliant Devices and Systems

4 Key Benefits of Point of Care Medical Device Interoperability More accurate data (10 to 20% errors introduced with data transcription) –Improved patient safety and care outcomes –Improved discharge decisions –Improved Case Management, Infection Prevention and QA More real time data available to MD, clinicians and care managers –More clinically sound diagnosis and orders –Earlier initiative of appropriate interventions and therapies –Prevention of undetected patient deterioration (failure to rescue) –More proactive patient management ( LOS, reimbursement) –Better outcomes Increased MD productivity and satisfaction Increased Nursing productivity and satisfaction –1 to 1.5 hrs day savings per RN or CAN Outcomes data warehousing

5 Barriers: Market Forces Healthcare organization financial priorities –Where is the ROI for medical device interoperability? –Each solution must be justified financially –Reimbursement drivers –Are you willing to pay more for standards? Would anyone buy an ultrasound without DICOM Vendors marketing one-size-fits-all –Do they really make financial sense? –Dont listen to these marketing or sales guys Talk to people who have actually implemented Sure, we can interface these widgets to your EMR

6 Safely, Effectively Rigorous validation, verification, and testing of medical devices is required This slows development to market timelines Were creating complex systems of systems requiring analysis

7 Complex Problems Most healthcare organizations do not have the staff to understand requirements of medical device interoperability –Sure it interfaces does to your EMR but what does that mean? We need to simplify the integration requirements –Vendor salespeople wouldnt be able to blow as much smoke Imaging devices as an example

8 Cultural Clinical Engineering and Information Systems have traditionally worked in silos Clinical Systems Engineer –A Hybrid employee Trend is partnering CE with IT –Neither one can do this alone AAMI-ACCE-HIMSS CE- IT Community

10 IHE International organization of manufacturers, standards organizations, and users –IHE is not a standard, IHE is a user of standards Identify and constrain standards to make them more user friendly and truly interoperable –Saying its a compliant IHE Image Acquisition Actor means a lot more than saying its DICOM –Claiming a Central Station is a Device Observation Reporter (DOR) means more than saying its HL7 Standards are broadly based while IHE drills down to specify the parts of standards that are normally ambiguous –Example: A medical device claiming to be a DOR must use HL7 v2.6 and must structure their HL7 messages in a way clearly defined by IHE, using message contents and semantics that is also clearly defined by IHE Vendors test their connectivity at annual connectathons

11 IHE Standards Adoption Process 11 Document Use Case Requirements Identify available standards (e.g. HL7, DICOM, IEEE, IETF) Develop technical specifications Testing at Connectathons IHE Demonstrations Products with IHE Improved safety, quality & efficiency! 11 Easy to integrate products

12 IHE Technical Frameworks Profiles –Describe clinical information management use cases and specify how to use existing standards (HL7, DICOM, IEEE 11073, etc,...) to address them. Actors –A system or application responsible for certain information or tasks. Each Actor supports a specific set of IHE transactions to communicate with other Actors. Transactions –An exchange of information between Actors. For each transaction a Technical Framework describes how to use an established standard (such as HL7, DICOM or W3C) to exchange information.

13 IHE Profile Transaction Actor

14 Alarm Communication Management Profile Clinical Objective: –Improve clinical efficiency by using technology to deliver the right alarms, with the right priority, to the right individuals via devices with the right content, and through configuration escalating communication of alarms to devices associated with other individuals Technical Objective: –Provide uniform way of representing common alarm conditions to facilitate interoperability of systems from different vendors

15 Alarm Source Alarm Aggregator Alarm Receiver Alarm Coordinator Alarm Disseminator Alarm Communication Alarm Endpoint Alarm Communicator (AC) Alarm Manager (AM) Alarm Reporter (AR) Alarm Reporter Alarm Cache Alarm Archiver (AA) Communication detailed in this profile Communication not detailed in this profile............ Communication of alarm information from patient care devices to an alarm manager system communicating with secondary means of notification to caregivers. Typical secondary notification means would be annunciators, pagers, and smart phones.

16 Use Cases Case A1: Location Sourced alarm (i.e. nurse call type alarms) Case A2: Identified Patient Source (i.e. physiological type alarms) Case A3: Same as A1/A2 with Escalation and Cancel at Alarm Reporter (AR) Case A4: Same as A1/A2 with Escalation and Cancel at Communication Endpoint Case A5: Same as A1/A2 with Escalation and Cancel at Alarm Manager (AM) Case A6: Alarm with no destination other than logging by the Alarm Manager (AM) actor

17 Case A1: Location Sourced Patient wants a pillow Patient pulls nurse call Nurse call system lights the rooms dome light and light at central station. Nurse call system, operating as an Alarm Reporter (AR) actor sends Report Alarm [PCD-04] to Alarm Manager (AM) indicating nurse call alarm. The Alarm Manager (AM) logs receipt of the alarm. The Alarm Manager (AM) identifies the appropriate nurse based upon configured nurse to patient assignments, identifies the appropriate Alarm Communicator (AC) actor and destination communication device based upon nurse to device configuration in Alarm Manager (AM), sends Disseminate Alarm [PCD-06] to nurses communication device. The Alarm Manager (AM) logs the dissemination to the Alarm Communicator (AC). The nurse receives the alarm on their assigned device. The information minimally includes the patient location (room number). The nurse goes to the room, determines the needs of the patient, and provides the patient with a pillow. The nurse then resets the nurse call pull. The nurse call system turns off the rooms dome light and the light at the central station. The nurse call system, operating as an Alarm Reporter (AR) actor sends Report Alarm [PCD-04] to Alarm Manager (AM) indicating reset of the nurse call alarm. The Alarm Manager (AM) receives the alarm turns off any configured alarm escalation and logs the alarm. AR -> AM AM -> AC AC -> Nurse AR -> AM

19 Leveraging IHE for purchasing How do you get IHE Integration Profiles? –Specify IHE capabilities as requirements –State in the RFP which IHE Actors and Integration Profiles you want. What do IHE Integration Profiles cost? –Nothing in most cases –Any cost should be a fraction of the overall

20 Why Specify IHE Specifying integration requirements for the system you are purchasing is a simple matter of selecting which IHE Integration Profiles and which IHE Actors you want supported When you tell a vendor you want a certain IHE actor they immediately know your interface specifications instead of requiring an extensive interface technical assessment Users can concentrate on the clinical requirements of their equipment – not how it is going to interface to other systems Removes custom interfaces as obstacles for future upgrades and additions

21 The business case for implementing IHE Profiles Enables you to efficiently manage the array of integrated information systems necessary to support effective healthcare The alternative –Building site-specific interfaces More expensive Requires maintaining these custom interfaces for the life of the system involved. Integration via IHE is less costly at the start and makes future acquisitions easier to plan and execute IHE Profiles give clear definitions of how the pieces fit together IHE Profiles come with initial unit testing done

22 What Can You Do? Plan, Evaluate, Purchase IHE Conforming Devices In continuing discussions with vendors – at all levels –Push IHE Interoperability Refer to lower deployment, maintenance costs –Encourage vendors active IHE participation Lower development, installation, support costs –Refer to profiles Leverage public and objective commitments In RFPs –Refer to profiles, Conformance Statements –Use Conformance Statements to nail down vendors representations –Adopt very specific language

23 Sample language The device shall support the IHE Device Enterprise Communication (DEC) Integration Profile as the Device Observation Reporter (DOR) Actor. The pump shall support the IHE Point-of-Care Infusion Verification (PIV) Integration Profile as the Infusion Order Consumer (IOC) Actor. The device shall support the IHE Alarm Communication Management (ACM) Integration Profile as the Alarm Reporter (AR) Actor. The alarm aggregator shall support the IHE Alarm Communication Management (ACM) Integration Profile as the Alarm Manager (AM) actor
