Bioclinical Data Warehouses & Translational Research : the HEGP Case Patrice Degoulet & Paul Avillach Faculté de Médecine René Descartes, Université Paris 5 Hôpital Européen Georges Pompidou (HEGP) INSERM UMR_S 872 eq22 August 2012 Why should we develop Bioclinical Data Warehouses 1. EHR driven research – Patient selection for CR studies (e.g., EHR4CR) – Biomarker discovery (phenotype-genotype) – Personalized medicine 2. Phenotypic augmentation for clinical research studies – Additional source of bioclinical data for cohort studies – Reuse of EHR data to feed a CR study • Prokosch HU, Ganslandt T.

TranSMART-based Ontology definition Proof of concept • R module in tranSMART • Published figure in JCO The HEGP BDW Conclusion (1) Achievements • A methodology to export concepts and data from an integrated CIS (2009-) • An operational CDW directly used by MD and Pharm (2011- ) • Installation & evaluation of a tranSMART platform to augment clinical data with omic information (2012-) Benefits of the approach • Availability of clinical data has generated a virtuous cycle at the HEGP end-user level (e.g., improved standardized questionnaires) • tranSMART is based on the i2b2 model for clinical data The HEGP BDW Conclusion (2) Limits of the approach • Lack of semantic integration tools to merge i2b2-tranSMART concepts • i2b2-tranSMART data model heterogeneity Perspectives • Semantic integration within the i2b2-tranSMART platform to enable: 1) meta-analysis from multiple cohorts 2) phenotypic augmentation in genomic driven research Acknowledgments www.i2b2.org Informatics & Public Health Dept. www.transmartproject.org Pierre Durieux, MD Eric Zapletal, PhD www.recomdata.com Kevin Zarca, MD Vincent Canuel, Resident Contacts : [email protected] [email protected] MIE 2012 – Panel on Clinical Bioinformatics August 27, 2012 New challenges for human-centered decision- support systems The Data Representation Challenge Presented by Amnon Shabo (Shvo) • Chair, Medical Informatics Community of IBM Research • Head of IBM HCLS* Standards Program • Co-chair & facilitator of HL7 Clinical Genomics • Co-editor of CDA R2, CCD and Pedigree IBM Haifa Research Lab (HRL) * HCLS = Healthcare and Life Sciences © 2012 IBM Corporation Haifa Research Lab Main Concepts 1. Flat representations are flat tires for CDS engines…! Health data semantics and context cannot be faithfully represented using flat structures (e.g., a list of entries), rather it requires a compositional language that associates various data entries to a meaningful statement 2 Haifa Research Lab The New Generation of Standards is Object-oriented! Observation Procedure Object Object Code Insert into basic Participant Medication health objects Code Object Grammar* Object Code SNOMED, LOINC, ICD, etc. Observation O1 (consisting of Observations O11 and O12 and related to Subject S1), is Clinical Statement the reason for Procedure P1 (performed by Clinician C1) which is the cause of Observation O2… Lab Pharma Docs Others * The grammar should be part of a health-dedicated reference information model, e.g., the HL7 RIM or the openEHR RIM 3 Haifa Research Lab Clinical Omics Statement ! § An effort within the HL7 Clinical Genomics Work Group § Latest effort: CDA Implementation Guide for Genetic Testing Reports (GTR) § An abstract Clinical Omic Statement (COS) template that § Has at its core a genomic observation (e.g., a DNA sequence variation) § If it’s a reportable finding, then it should be associated with indications and interpretations, specimen and genomic source class § The major finding can be associated with associated observation (e.g., amino acid change) § Optionally, performers may be specified (overriding header performers) § The COS abstract template is instantiated by specialized COS’s, e.g., for genetic variations or cytogenetics Associated Observations Indications Omics Interpretations Performers Observation Clinical Genomic Statement Clinical Genomic Specimen Source * Taken from the HL7 CDA Implementation Guide for Genetic Testing Reports. 4 Haifa Research Lab Main Concepts 2. ‘Encapsulate & Bubble-up’… Personal biological key data should be encapsulated in its native format into clinical data structures, where 'bubbled-up' items could be associated with phenotypic data, as part of clinical data standards 5 Haifa Research Lab Clinical Genomics Data Standards: Encapsulate
