Cross Domain Patient Identity Management Eric Heflin Dir of Standards and Interoperability/Medicity
Audience/Scope • Audience • Senior Healthcare IT Technical Executives • Implementation Architects • Implementers seeking an overview • Scope • Broad context and guidance about the use of IHE standard profiles for patient identity management
Definitions • Patient Identifier: A value controlled and assigned by a single assigning authority (hospital, group of related practices, national health authority, etc.). • Assigning authority: • XDS Affinity Domain: <get from Charles> • <why did we group these together, perhaps have a diagram showing the interplay between the profiles>
What Problem is Being Solved? • Problem statements: • How can we accommodate exchange of health information across organizational boundaries requiring identification of the same patient in different systems with different IDs using a standards-based approach? • Assurance that health information is about the correct patient via correct identification of the patient of interest <wordsmith>
IHE Approach • IHE has created several mechanisms, or “profiles”, designed to solve this problem • PIX, PIXv3, PDQ, PDQv3, XCPD, PAM
PIX Definition • PIX = Patient Identifier Cross Referencing • Definition: Allows a patient identifier assigned by one assigning authority to establish and maintain an identifier relationship assigned by another assigning authority • Status: “Final Text” • <review wiki page def text>
PIX v2 vs. PIX v3 • Identical purpose, different underlying standards • HL7 v2 messaging is used for PIX v2 • HL7 v3 messaging is used for PIX v3
PIX Use Case • Use case <pull from the Wiki> • <get content from Charles, may have in ppt format> • <TF vol 1, section 5>
PIX Transaction Diagram • Insert transaction diagram from ITI TF
PIX Actors • List each PIX actor • List each PIX transaction
PIX Options • List and define each PIX option
PIX Workflow(s) • List one or more typical workflows • Should be a less technical diagram, like the appendix, not a UML sequence diagram
PIX Security and Privacy • Describe how security and privacy are implemented for this profile
PDQ • PDQ = Patient Demographic Query • PDQ is designed to allow for a query across domains using, as the name implies, demographic information • Status: Final Text? • Other topics…
PDQ Use Case • Use case
PDQ Transaction Diagram • Insert transaction diagram from ITI TF
PDQ • List and define each PDQ actor • List each PDQ transaction
PDQ Options • List and define each PDQ option
PDQ Workflow(s) • List one or more typical workflows
PDQ Security and Privacy • Describe how security and privacy are implemented for this profile
PDQ Typical Architecture • Simplistic architectural diagram
XCPD • <covered by karen, sync up with her> • XCPD = Cross Community Patient Discovery • XCDP is designed … • XCPD is different than PDQ in the following ways… • Async, optimized, reverse query, etc. • Used for the Nationwide Health Information Network Exchange 2010 Patient Discovery Production Specification
XCPD Maturity • Relatively new profile, just entering first year of “Trial Implementation” status • Deployed by NHIN Exchange participants • Will be demonstrated for the firs time at the 2011 IHE Connectathon?
XCPD Use Case • Use case
XCPD Transaction Diagram • Insert transaction diagram from ITI TF
XCPD Actors • List and define each XCPD actor • List each XCPD transaction
XCPD Options • List and define each XCPD option
XCPD Workflow(s) • List one or more typical workflows
XCPD Security and Privacy • Describe how security and privacy are implemented for this profile
Typical XCPD Architecture • Simplistic diagram
Patient Administration • Repeat the above for PAM
