Abstract The Duke Biobank has selected LabVantage to be theenterprise-wide biobanking Information Management System to unify clinical research biobanking informatics. Biobanking terminology across Duke developed in silos with no coordination and lacks semantic interoperability. In order to promote interoperability and to decrease the probability of errors with the central development and management of biobanks within LabVantage, The Duke Biobank has initiated a project to develop a standard terminology for biobanking, sample processing, and assay result metadata. • Method • To facilitate interoperability across the enterprise Duke Biobank has invited a group of stakeholders across the organization to participate in the development of the common terminology. The common terminology will consist of data elements that include the following (Figure 1): • data element name • data element definition • permissible values and • definitions for permissible values • Reference - NCI and ISBER as authoritative sources/primary sources for terminology • Stakeholders are encouraged to identify terminology from existing standards, systems, initiatives and publications then come to a consensus on a common name and definition. Figure 2. Project Organization Structure • Results • The biobanking domain was divided into 5 categories and each one was assigned to a working group to identify and develop data elements and their associated definitions (Figure 2). • Working Groups consist of 4-6 members drawn from clinical researchers and biobankers across Duke that meet weekly or bi-weekly for the last 6 months. • Facilitators and Informatics Lead provide project management and technical assistance for working groups in the development of the content. • The Oversight Committee provides the governance, leadership and monitors the overall project. Background The lack of standards leads to ambiguous exchange and hinders understanding and interpretation of information within clinical research 1,2.Implementing a consensus developed semantic set of data elements into the biobank will hopefully improve data, management, exchange and reuse across the organization. A methodology based on previous data standards project is being followed for creating therapeutic or domain specific data elements3. There exists no standard terminology for clinical or translational biobanking. The deployment of an enterprise-wide biobank information management system would benefit from a standard terminology that would be used across all biobanks and research projects. The Duke Biobank has begun the development of a standard terminology which will be used in the implementation of LabVantage for the enterprise-wide biobanking platform. Draft Acknowledgements: The project described is funded in part by the National Center for Advancing Translational Sciences (NCATS) a component of the National Institutes of Health. Clinical and Translation Science Award (CTSA) grant Conclusion Duke will vet the drafted terminology with a broader set of stakeholders during a public comment periond before incorporating it into the biobanking system. A governance and maintenance process will be developed to ensure the terminology is current and meets the needs of the enterprise and stakeholders.
