The Current State of Clinical Information Healthcare information is found in paper medical records, in disparate databases, in hospital- based information systems--- there are islands of data Clinical research data may exist in additional databases and/or research notebooks Clinical trial data is collected on 3-part NCR forms (~90% of trials) or via a multitude of electronic data capture applications
Current Technology Issues in Conducting Clinical Trials Electronic Data Capture (EDC) and/or eClinical Trials and new technologies are being piloted (if not adopted) by the major pharma companies. Sources for electronic data are many and varied (e.g. EDC, IVRS, hand-held diaries, clinical laboratories, AE databases); ready retrieval of electronic data is very important. Investigative sites are dealing with multiple and varied systems and interfaces.
Many industry stakeholders have realized that proprietary data structures are not necessarily of value….instead, focus should be on the molecule---the therapy. Innovation depends upon standardization. –Dr. Bob ONeill, Director, Office of Biostatistics, CDER, FDA
The Future: Standards to Facilitate Data Flow ….from Source to Reviewers Operational Database SDS ADaM ODM LAB eSubmission for Regulatory Review CRO EDC LAB ECG Sources of electronic data
Clinical Data Interchange Standards Consortium CDISC is an open, multidisciplinary, non-profit organization committed to the development of worldwide industry standards to support the electronic acquisition, exchange, submission and archiving of clinical trials data and metadata for medical and biopharmaceutical product development. The CDISC mission is to lead the development of global, vendor-neutral, platform-independent standards to improve data quality and accelerate product development in our industry.
CDISC History Started as grass roots volunteer group in Fall 1997 with 25 attendees at first meeting Invited to form DIA SIAC in 1998 Independent, non-profit organization in February 2000 ~130 Corporate Memberships, of which ~50 are Corporate Sponsors (e.g. global pharmaceutical companies, CROs and technology providers) Originally two working teams (Nomenclature and Modeling); Modeling split modeling into four teams; Nomenclature to Glossary Group Models developed by consensus-based process

Speaking of health benefits/opportunities to be realized from making more effective use of IT…. I think that CDISC will be a big part of moving FDA onto an electronic information architecture where we can realize all of these opportunities. I think this will have a profound and positive impact on our drug review process, allowing us to design trials that can be less expensive and still tell us more about the risks and benefits of a new medical product. And I think that the most significant and perhaps enduring legacy to your efforts could be the very immediate and significant impact it has on improving the lives of patients. –Mark B.
