For more information on the MURDOCK Study, please visit us online: www.murdock-study.com Introduction The Measurement to Understand the Reclassification of Disease Of Cabarrus / Kannapolis (MURDOCK) study is a longitudinal health study aimed at reclassifying health and disease by investigating genotype and phenotype associations. 1 As part of the study, a large sample of volunteer participants is being recruited in Cabarrus county/Kannapolis, North Carolina. To support participant recruitment efforts, software infrastructure has been developed including a community registry and a biorepository. One of the community registry’s purposes was to house self- reported participant data and participant data imported from electronic health record (EHR) systems. Results Provides self-describing data at a finely granular level Accommodates data storage for over 9,000 participants and 20,000 participant questionnaires (including follow-up) Contains 131 data elements Supports 4 different form versions “Rewriting the textbook of medicine” Disclosure Information Authors listed here have nothing to disclose concerning possible financial or personal relationships with commercial entities that may have a direct or indirect interest in the subject matter of this presentation. Figure 2 (above): Entity Relationship Diagram for Metadata model and corresponding participant reported data storage. The Metadata model is based on the ISO/IEC 11179 Metadata Registries (MDR) Standard 2, HL7 v3 standards and the Virtual Medical Record Standard 3. Each question is represented as a Data Element.
