PHR: Definition Personal Health Record (PHR): “a set of computer-based tools that allow people to access and coordinate their lifelong health information and make appropriate parts of it available to those who need it” Patient owns his/her record 7 D. C. Kaelber, A. K. Jha, D. Johnston, B. Middleton, and D. W. Bates. Viewpoint paper: A research agenda for personal health records (PHRs). JAMIA, 15(6):729–736, 2008

Slide 21

MyPHRMachines, revisited: Beyond software industry efficiencies Top four PHR research opportunities: PHR function evaluation, PHR adoption and attitude analysis, privacy and security solutions, architectural solutions. 21

Slide 22

A novel PHR System Architecture (revisited) Architecture of all other PHR systems Conventional Service Oriented Architectures Remote Procedure Calls “If you want my service, give me your data” Architecture of MyPHRmachines “If you want to service, give us your software” Trusted Broker (platform) Patient-owned Virtual Machine sessions Stateless Connectionless 22 Inversion of Control

Slide 23

Conventional Service Oriented Architectures (SOAs) “If you want my service, give me your data” 23

Slide 24

Recap: Conventional SOA Image Source: 24 Secure RPC mechanisms well understood What happens with your data at the remote server?

Slide 25

But isn’t HIPAA protecting us? Well, let’s check HealthVault (based on Indivo Architecture) Prestigious example: Mayo Clinic’s HealthVault plugin Privacy Statement (contract, terms of use) 25

Slide 26

Mayo Clinic: Privacy Statement How your Personal Information is stored The Service temporarily stores or "caches" Personal Information as necessary to provide you the Service. The Service does not permanently store any of your Personal Information. All of the Personal Information you enter, edit or view in the Service is held only temporarily by the Service. Information you enter or edit in the Service is added to your Microsoft HealthVault account once you hit "Save." 26 Acceptable for a respected service provider such as the Mayo Clinic But what if their sysadmin screws up? Also: how to enable worldwide competition on disruptive innovation in HC?

Slide 27


Slide 28

28 Can the average citizen be expected to understand this? Replace by “Wonder service XYZ”

Slide 29

Proposal Trust your PHR data once to a secure, HIPAA-governed platform Platform architecture should provide hard guarantees concerning privacy Persuade the smart/skeptical ones Protect the ignorant ones 29

Slide 42

42 Part 2: Boston Collaborations

Slide 43

Generic Interview Questions Q1: Should patients get access to all their medical data? Q2: Should PHRs contain data that is invisible to the patient? Q3: To what extent should patient data first undergo a filtering / translation step? (to layman’s terms) Q4: Please assess the relevance of the VM based architecture Privacy: how relevant? Complex SW: how relevant? Q5: Business Model? Q6: Publication, role of interviews/validation 43

Slide 44

Concrete Collaboration Options Focus: CDS/MyPHRMachines, focus on architecture Option 1: Deploy legacy CDSS in MyPHRMachines Option 2: Use MyPHRMachines as CDSC audit platform Option 3: PersMed elaboration (SMC validation) Option 4: Use Indivo/SmartPlatforms as the backbone 44 #PHR @pvgorp

Slide 46

Personalized Medicine in the Cloud Building a secure AppStore for Monogenetic Diseases and More 46

Slide 47

Example: Leukemia Treatment (1/3) 47

Slide 48

Example: Leukemia Treatment (2/3) Reflection: (ex) Research Fellows, raise your hand “we do this for the patient” Brother gives bone-marrow transplant Highly Motivational Colleague But the story continues… Wartman: “Seven months after the transplant, feeling much stronger, he went to a major cancer meeting and sat in on a session on his type of leukemia. The speaker, a renowned researcher, reported that only 4 or 5 percent of those who relapsed survived.” Relapse (NY Times, Start: 1m40s, Stop: 4m10) Team Lead: “Why not throw everything we have at seeing if we can find a rogue gene spurring Dr. Wartman’s cancer?” 48

Slide 49

Analysis of RNA 49

Slide 50

Example: Leukemia Treatment (3/3) Online discussions of article: ethical debate about money spending, access to SotA MyPHRMachines “business model”: provide an appstore for genomic diagnostic services Insurance can cover some services, Anyone has the right to pay 10$ out of his/her pocket, without compromizing confidentiality Vision: global market (beyond US, EU) Competitive (patient ratings, price competition, …) Need hard guarantees w.r.t. privacy MyPHRMachines’s VM-based architecture 50

Slide 51

Choice of extra demonstrator: service for Monogenic Diseases result from modifications in a single gene occurring in all cells of the body >10,000 of human diseases are known to be monogenic Canada: monogenic diseases may account for upto 40% of the work of hospital based pediatric practice (Scriver, 1995) Why access services? “Early treatment of thalessaemia has proved to be very effective in improving the quality of life of patients. Currently, genetic testing and counseling, and prenatal diagnosis play an increasingly important role in informing individual as well as professional decisions around the prevention, management and treatment of this disease” 51

Slide 52

Concrete Demonstrator Use of PolyPhen2 for BRCA1 PolyPhen2 has been hard to use so far, still open to Alternative service examples Alternative platforms 52

Slide 53

Other emerging stories!comment=1 Can Genomic Medicine Be Clinically Useful Yet? Husband of woman with “Peritoneal cancer” “Cancer elicits a primal fear that can provoke fantasy and baseless speculation.” Useful insights: … suggests that her cancer may respond to targeted drug therapies like those that have been effective for many breast cancer patients – tamoxifen, for example …  eliminates the notion that treatments aimed at HER2 mutations could be beneficial. Again: leverage your sequenced genome, leverage software services as they mature 53

Slide 54

Commercial SotA, 2012 <<function>> 54 Future: out-sourcing parts of pipeline. Future: patient will get/leverage result of sequencing.

Slide 55

Commercial SotA, 2012 <<achitecture>> 55 Why trust this cloud? Also: too monolithic?

Slide 56

Conclusion Triggered by own frustrations concerning inefficiencies of care system (duplicate scans), simple solution for DICOM content (old stuff). Leading to advanced demo for the future of medicine “App store” platform for diagnostic services App developers do not have to worry about HIPAA App users have real peace of mind EU/NSF funded demo platform, need “Apple” partner to commercially develop the MyPHRMachines app store and data repository? Or start-up? 56

Summary: Abstract: in this talk, I will describe recent developments on MyPHRMachines [1,2], a prototype of a PHR system with a radically new architecture. I will first briefly introduce the architecture and compare it to the architectures of mainstream PHR systems. Then, I will give a hands-on demo of the system, I will describe the status of my work at Partners and I will provide sufficient time for discussing this work and the future of MyPHRMachines.
