The views expressed herein are soley those of Stephen A. Weitzman, J.D. LL.M. Executive Director of MedDATA Foundation.

THERE ARE THREE TECHNICAL PROBLEMS
A platform and methods for sharing data in a way that it can be analyzed for all the good purposes
Standards and Common Data Models for all disease areas
Incentives for the Pharma and Healthcare Systems Silos to share data – (The Silos include – holders of post market patient medical records- and pharma companies that hold the premarket data that shows safety and efficacy or lack thereof)

INFRASTRUCTURE:You can’t communicate or share
without it.

SECOND PROBLEM: SHARING DATA
MedDATA FOUNDATION 7
THERE ARE TWO SETS OF SILOS
POST MARKET MEDICAL RECORD DATA
PREMARKET CLINICAL DATA SHOWING SAFETY AND EFFECTIVENESS OF THERAPIES

THE SECOND PROBLEM
It is argued that we do not have data standards. That is not true. We do have medical record formats in current use by pharma companies by which data is collected in clinical studies and submitted to FDA or EMA for evaluation of safety and efficacy. If we use these data structures then we can collect and merge post market data with premarket data in the same way that FDA evaluates data.
It is time to create incentives for pharma to make disclosure – full transparency- of protocols and clinical data of approved therapies available – to advance creation of the next generation of therapies.

In the United Kingdom
Data in Silos are collected into a Central Database for Querying and Analysis
The database is the GPRD/CPRD with 12 million patients and over 60.0 million records
The database is to be expanded to 55 million patients

PCAST 2010
“In other sectors, universal exchange standards have resulted in new products that knit together fragmented systems into a unified infrastructure.”
“The resulting ‘ network effect’ then increases the value of the infrastructure for all, and spurs rapid adoption.”
“By contrast, health IT has not made this transition.” “The market for new products and services based on
health IT remains relatively small and undeveloped compared with corresponding markets in most other sectors of the economy, and there is little or no network effect to spur adoption.”

U.S. Solution: A Distributed SystemReasons
1. Data is kept in the hands of the original data holders
2. Decrease proprietary and liability concerns 3. Decrease risk and severity of data breaches4. Data holders know their data; improve value
and better interpretation of findings5. Minimize data transfer; minimum necessary6. Voluntary – data partner autonomy7. Reciprocity – value for participation8. Partnership9. Well-defined purpose

Solution: Query Distribution/Response
1- User creates and submits query (a computer program)
2- Data partners retrieve query
3- Data partners review and run query against their local data
4- Data partners review results
5- Data partners return results via secure network
6 Results are aggregated

Disagreement and Agreement with Rationale For Distributed Model
(OK for Epidemiology but not for Decision Support or other Real-Time needs)
1. Data must be kept in the hands of the original data holders – (In the U.S. we will never get a central database)
2. Decrease proprietary and liability concerns – Can Be Handled3. Decrease risk and severity of data breaches – Disagree4. Data holders know their data; improve value and better
interpretation of findings – DisagreeData in distributed system is not uniformly indexed or coded
5. Minimize data transfer; minimum necessary –(Security Issue)6. Voluntary – Data partner autonomy (Same as 1)7. Reciprocity – Value for Participating: Access more data8. Partnership 9. Well-defined purpose

1 – Mirror Data and 2
Index
1. Data held by partners is mirrored at their location (Silo)2. Mirrored data is "reindexed" 24/7 in a uniform manner using NLP and Auto-Coding3. Indexes (inverted files) of partners are aggregated in central computer 24/74. User selects data sources and creates and submits query to "central" portal 5. Query locates data in the partner sites through the central index6. Data relevant to the query is aggregated in a cloud 7. Analytics is applied to generate the report 8. Obtain results and publish with reference to sources of data (trail)9. Erase data

Alternative: A Hybrid System& Reasons for Hybrid
The System is Data Agnostic, and Query System Agnostic Can access all available data for that user based upon data use agreements Data is kept in the hands of the original data holders (Same as distributed) Hybrid system is more efficient - Scalable (New Silos add Pointers to Index,
“Catalog”) Hybrid system can obtain results faster Hybrid system can be multi-purpose
Outcomes Research (CER) Drug Safety Signaling (surveillance) Personalized medicine Make Clinical Research More Efficient
Rapidly design and implement observational trials Quickly and affordably conduct randomized studies Significantly reduce usual expenses associated with start-up and shut-down of clinical
research studies Identify patients for clinical studies
Data is uniform – NLP and Coded to Snomed-CT Reciprocity – value for participation (Same as distributed) Partnership (Same as distributed) Well-defined purpose (Same as distributed)
