The IHE North America kicked off their Connectathon yesterday. This is the second year (?) that the Patient Care Device domain (PCD) has had something to show in the Interoperability Showcase at HIMSS.
I chatted with Todd Cooper via Skype and received the following update:
As background, there are approximately 390 engineers from 70 companies and 2 university groups connecting 136 different systems. On the PCD side, we have the following groups participating:
- GE Healthcare
- Welch Allyn
The profiles being tested are primarily focused on device data gateway reporting to enterprise applications (this fall the PnP profile will start active testing), and includes the basic PCD-01 message from last year (an HL7 v2.5 message with ISO/IEEE 11073 semantics - a consistent message format containing consistent device-related semantics). Also there is a profile for how these "gateway" systems handle patient demographics data and bind patient ID's to the data streams, as well as use an HL7 Publish/Subscribe mechanism for configuring which information should be reported.
As for process, each vendor has a set of stand-alone, one-on-one and one-on-many tests. Once they think they have things working and are ready for verification, they call over one of the Monitors (independent observers) who observe each step of the test, and if all works, approve the verification or if they don't work ... have the companies go back and figure out what's wrong, etc. For example, earlier this afternoon two companies thought they were ready. OK - "change that parameter" ... <waiting ... waiting ... waiting> "Hmmm...didn't ever change on the other side ... Call me when you're ready!"
Reps from IHE and the PCD are discussing how devices will be integrated into the upcoming HIMSS '08 IHE Showcase. Including medical devices for the first time last year clearly brought out the need to move from the cold I.T. world to include the clinical environments that they are supposed to be supporting ... hmmmm...go figure! Last year PCD was in the Showcase, but mostly a separated area. This year, they will be integrated to the overall story line.
Most of the vendors participating in this year's PCD Connectathon have products in markets where verified IHE support is a key part of the vendor selection process. All of the current participants recognize that it is only a matter of time until such requirements will be applied to patient monitors, infusion pumps, ventilators and other types of medical devices.
Vendors who wait much longer to get involved in the PCD will end up implementing connectivity solutions defined by other vendors, and will have a growing body of work to "catch up" to vendors who jump in early.
Providers are encouraged to participate as well -- unless you're okay with everything designed to convenience vendors rather than users. So far, Kaiser and Partners have been the only provider organizations to participate.
