Requirements for a Softw areI ntensive Ecosystem for Telemedicine By Christensen, Christensen, Hansen, Kyng, Manikas, Surrow, and Urazimbetova Med-e-Tel, Luxembourg, May 2012 Speaker: Henrik Bærbak Christensen Aarhus University www.net4care.org www.net4care.org Net4Care sponsors and participants... The Challenges Denmark faces – Demographic changes: More old people, less young • In 2044: 60% more elderly people than today • (And Denmark has high birth rate: 1.8 child pr women) – Life-style related chronic diseases increase • In 2009: Estimated 80% of public health expenditure Similar challenges in other developed countries Part of a solution: Telemedicine – ”Out-patient clinic” in the home • Measurement upload, video conferencing www.net4care.org Net4Care: The Vision Observations – Many experiments but... • End-to-end / Silo solutions... • Too expensive, too complicated, too broad • Abandoned when project money ceases Vision – – – – Software Ecosystem for Telemedicine Open source reference implementation Modular, reusable, flexible SMB marketplace www.net4care.org Software Ecosystems Working definition – A software ecosystem consists of a set of actors and software elements in a domain interacting as a system Some examples – Microsoft Office – Google Android, AppEngine Contrast – Product Lines (single vendor) www.net4care.org Easy at first look... Many pieces apparently already there... – HL7 v2 and v3 • Formats for messaging and clinical documents – IHE profiles • XDS: Cross Enterprise Document Sharing • Repository and Registry for storage – MedCom standards and web services • Danish successful initiative www.net4care.org ... But not quite.. (Very) steep learning curve – HL7 documentation overwhelming but reference type • Requires you to know it before it really makes sense – Examples and code related artefacts hard to find Only propriatary (expensive) environments – Prohibitively high initial cost – Not appropriate for research/education institutions Either no or transient testing environment – No sandbox for testing and experimentation – ”Code working today does not work tomorrow” www.net4care.org Initial focus Clinical observations in the home / monitoring – Diabetes, COPD, blood pressure, … Application-centric Ecosystems – Simplify contribution – Extends data models www.net4care.org Business Scenario Developer in SMB wants to develop spirometry application for the home – Measure spirometry data by easy user interface – Upload measured FVC and FEV1 to national XDS servers for access by all regional EHR and GP systems 1st prototype of such system running in 4 hours! www.net4care.org www.net4care.org Provide... Status A very initial version of the framework is available – – – – http://www.net4care.org (Some) Tutorials with demo code Open source implementation Staged testing environment Validation and further development on-going ☺ First ‘organisms’ are moving into the ecosystem www.net4care.org
