XDS for Mobile Health Brief Profile Proposal for 2009/10 presented to the IT Infrastructure Planning Committee Keith W. Boone September 22, 2011

IT Infrastructure Planning Committee The Problem Support for XDS in mHealth Evironment mHealth platforms are resource constrainedmHealth platforms are resource constrained –SOAP Stack missing or buggy (e.g., WSDL support for Objective C) –Bandwidth constrained (10Kbps to 10Mbps) –Limited resources (e.g., memory), often no “back-end” server Increasing proliferation of unconnected appsIncreasing proliferation of unconnected apps –~9,000 consumer health apps 1 in Apple’s App store –~13,000 by 2012 mHealth is an emerging market, failure to support this space could reduce relevance of IHEmHealth is an emerging market, failure to support this space could reduce relevance of IHE Difficult to use XMLHttpRequest for browser based, multiplatform mHealth apps.Difficult to use XMLHttpRequest for browser based, multiplatform mHealth apps. 1 Source: MobiHealthNews

IT Infrastructure Planning Committee Use Case Patient sees a specialist for a particular condition. The specialist asks for detailed information from the patient. The patient, not remembering their list of medications, pulls out their mobile device and activates an application. The application queries the HIE and retrieves a list of clinical summaries in date order, from most to least recent (or on-demand medication list document). They select the most relevant document, and it is downloaded to the device. The application extracts and displays their medication list.

IT Infrastructure Planning Committee Proposed Standards & Systems StandardsStandards –XML –XDS Metadata –ebXML –XSLT –JSON, JSON Schema –XmlHttpRequest –OHT Restful API SystemsSystems –EHR, PHR, Patient Portal, HIE, Mobile devices

IT Infrastructure Planning Committee Discussion There has been substantial work already in simplifying the XML in OHT, that could be used as one basis for the effort.There has been substantial work already in simplifying the XML in OHT, that could be used as one basis for the effort.
