Tonight's HIT Standards Q&A Tweetchat (5:00PM ET) will be on IHE Profiles from IT Infrastructure dealing with patient identity management.
Originally, it was going to cover ITI, Patient Care Coordination, and Quality, Public Health and Research domains. But, last week there were a number of questions about Patient Identification, and I hope we focus on what IHE has to offer in this space. IHE IT Infrastructure profiles support the following.
First, there is Patient Identity Cross Referencing (PIX). This profile is designed to allow an EHR or other Health IT system to integrate with a Master Patient Index using HL7 Version 2.3.1 and 2.5.1 messaging. If you know the ID of the patient in one domain, this profile allows you to find the ID of the patient in another domain.
Next there is Patient Demographics Query (PDQ). This profile allows you to search for patient identities based on patient demographics. You can locate all of the matching identities, or just those from a specific identity domain. This also uses HL7 Version 2, but this time, just 2.5.1 to support the queries. PIX/PDQ are rarely found implemented separately, but they are written as separate profiles.
A few other countries require the use of HL7 Version 3 messaging to access this information, so IHE created a HL7 Version 3 edition that has the same capabilities, called PIX/PDQ Version 3 (PIXV3 and PDQV3).
Identifying patients from one HIE who might have records in another is a more significant challenge. The Cross Community Patient Discovery (XCPD) profile builds off of the PIX/PDQ V3 work. It needs to use web services to perform the exchange for various reasons.
Finally, there is Patient Administration Management (PAM) which uses HL7 Version 2 to address general patient administration (ADT) messaging, which is where a patient identity usually enters the system.
One reason for the focus on Patient Identity is the ONC Advance Notice of Proposed Rulemaking on Metadata for Health Information Exchange. You can find my thoughts on that rule here, and an initial post and a more detailed on with answers from John Moehrke as well.
I look forward to your questions.

Transcript from HITstd Chat on HL7 CDA
I probably won't post the transcript after every HITstd tweet chat since you can get it online, but here is the transcript from our very first. We included CDA experts from around the world, including the US, Australia and South America to answer your questions about CDA.

| motorcycle_guy |  | Five minutes until the #HITstd tweet chat starts. Join us at http://tweetchat.com/room/HITstd #HITstd |
| mjadala |  | Hello all, glad to join this chat! #HITstd |
| diegokaminker |  | Hi I consider me to be half-expert, half-querant and the other half too! #HITstd |
| motorcycle_guy | | @mjadala Are you a querant, expert or fly-on-the-wall? #HITstd |
| mjadala | | Madhur Jadala from IL; worked in HL7 2.3, 2.5; trying to learn about ccd, cda; Querant here #HITstd |
| motorcycle_guy | | @GrahameGrieve Good Moooorning Australia, and welcome Grahame. Glad you could make it. What time is is there? #HITstd |
| TheGr8Chalupa |  | Erica Olenski, managing editor of @HealthStandards. Versed in #HL7, but always open to learn from the experts! #HITstd |
| theEHRGuy |  | Hi, my name is Michael Planchart and I have experience with HL7, DICOM, IHE and HITSP. #HITstd #HIT100 #HealthIT |
| mjadala | | We do not use ccd a lot now, but are exploring its use when working with hospitals on elr electronic lab reporting. #HITstd |
| mjadala | | Hello erica, graham & rest.. #HITstd |
| NateOsit |  | Nate here, friendly Health IT geek! Most likely fly on the wall, but may jump in w/ a question! #HITstd |
| diegokaminker | | No questions yet? I have one question for Keith..re Meaningful use and #CDA/#C32 - is there any change for meaningful use Stage 2? #HITstd |
| diegokaminker | | @GrahameGrieve it refreshes itself every # seconds if you are in tweetchat #HITstd |
| mjadala | | #HITstd what is the current adoption rate of cda vs ccr etc? |
| motorcycle_guy | | @diegokaminker With respect to #CDA and MU Stage 2, I expect HIT Standards Committee to discuss Consolided CDA guide for transfers #HITstd |
| HITExchange |  | Anyone using #CDA to draw out data for MU quality reports? #HITstd |
| diegokaminker | | @motorcycle_guy @GrahameGrieve Oh I´ve got it now- We need to update SouthAmerica. At least 5 countries using CDA R2 #HITstd |
| motorcycle_guy | | Welcome @rjhornii, sorry you cannot stay long. Maybe we can drag you in for DICOM discussion #HITstd |
| starkehealth |  | Hi there. Jomo Starke, Manager of HIE for SynerMed, versed in HL7 and HITSP. Multitasking, fly on the wall today. #HITstd |
| GrahameGrieve |  | @motorcycle_guy ta. I can edit, but how do we get people to register? #HITstd |
| motorcycle_guy | | @mjadala Hard to tell. At least 400+ systems read BOTH. These systems have demonstrated CCD/CDA creation: http://bit.ly/pXYZaP #HITstd |
| motorcycle_guy | | RT @HITExchange: Anyone using #CDA to draw out data for MU quality reports? #HITstd |
| motorcycle_guy | | @HITExchange I get a LOT of questions on extracting CDA data 4 quality reporting. I would have to say that many are trying it. #HITstd |
| motorcycle_guy | | @mjadala No hard data on creating CCRs publicly available. #HITstd |
| mjadala | | “@motorcycle_guy: @mjadala No hard data on creating CCRs publicly available. #HITstd” thanks Keith |
| rjhorniii |  | How many quality use problems are format vs content related. E.g., using diagnostic codes chosen for billing purposes. #HITstd |
| motorcycle_guy | | @rjhorniii Excellent question. A number of retooled measures use billing codes. Unfortunately it seems the only codes many have. #HITstd |
| motorcycle_guy | | How many of you would prefer to drop #HL7 V2 for immunizations and lab reporting, and just go #CDA all the way? #HITstd |
| GrahameGrieve | | @motorcycle_guy I would prefer to use CDA for these "reports" which are clinical documents - but they also need process (=v2) #HITstd |
| motorcycle_guy | | @GrahameGrieve @motorcycle_guy #hitstd |
| mjadala | | #HITstd currently scrambling to accept hl7 2.5 for elr to meet #MU |
| motorcycle_guy | | @GrahameGrieve What process would be needed? #hitstd |
| diegokaminker | | @motorcycle_guy maybe as an option...it will be great #HITstd |
| GrahameGrieve | | @motorcycle_guy - for labs, ordering and reporting are tied, and ordering = v2. Immunization - also subject to ordering here in Oz #HITstd |
| kim_nolen |  | Me too! @NateOsit: Nate here, friendly Health IT geek! Most likely fly on the wall, but may jump in w/ a question! #HITstd |
| motorcycle_guy | | RT @GrahameGrieve: I would prefer to use CDA for these "reports" which are clinical documents - but they also need process (=v2) #HITstd |
| motorcycle_guy | | So, @NateOsit, what do you want to know about #CDA? #HITstd |
| NateOsit | | @motorcycle_guy I guess my Q would be how well can CDA interface w/ systems using non-HL7 messaging? ie: Epic, Meditech, etc #hitstd |
| motorcycle_guy | | @NateOsit Old news right in your back yard: South Shore (Meditech) exchange #CDA with Atrius (Epic) via XDS http://bit.ly/rfHoZW #HITstd |
| motorcycle_guy | | @mjadala What is your biggest #CDA Challenge? #HITstd |
| diegokaminker | | Has anyone tested trifolia to manage CDA templates? Any comments on the experience? #HITstd |
| motorcycle_guy | | RT @diegokaminker: Has anyone tested trifolia to manage CDA templates? Any comments on the experience? #HITstd |
| motorcycle_guy | | Just a few minutes to go. What topics would you like us to address in future chats? #HITstd |
| diegokaminker | | Another one...Are we going to have (someday) a central repository for ALL CDA R2 templates...no matter who generated them...? #HITstd |
| Cascadia |  | RT @motorcycle_guy: Just a few minutes to go. What topics would you like us to address in future chats? ^patient identification #HITstd |
| motorcycle_guy | | @diegokaminker #ONC @SIframework is supposed to be developing a repository for artifacts through tooling contract. #HITstd |
| diegokaminker | | Will this repository be "global" or only for the US? #HITstd |
| motorcycle_guy | | Thanks for joining the #HITstd chat. Join us again in two weeks for a discussion of IHE profiles from ITI, QRPH, and PCC #HITstd |
| diegokaminker | | Thank you for the answers and the great idea! Hope a lot more people join for future sessions! I will invite all the HL7 ELC course #HITstd |
| diegokaminker | | And you will get >400 participants :) #HITstd |
