MHD

• Designed for sharing of documents– JSON representation of XD*

meta-data– RESTful access to XD*

infrastructure– Patient identity not scoped

but guidance exists• Can be performed by the

recipient/responder• Bracelet number = enterprise

identity

• Difficult to get demographics information

XD* / OtherInfrastructure

MHD MHD

PIX / PDQ

• Established patient identity X-Ref and Demographics query

• Not suited for mobile– PIX/PDQ (HL7v2) • Inconsistent support for socket programming on mobile• Lightweight browser apps (JavaScript) = nearly

impossible without gateway

– PIX/PDQ (HL7v3)• Inconsistent support for SOAP + WS* on mobile• Same issue for lightweight browser apps

Mobile Patient Discovery

• Seeks to profile mechanisms for mobile / lightweight clients to:– Resolve patient identities from a known identifier

(similar to PIX)– Retrieve demographics information from structured

query (similar to PDQ)– Leveraging existing projects in mHealth community

• Complementary to MHD – Similar: PIX/PDQ complements XDS– Similar: XCPD complements XCA
