    7. Clinical Trials System at COH • Over 400 ongoing trials at City of Hope • 30-40% of COH patients enroll on one or more trials • 1/3 pharma, 1/3 cooperative group, 1/3 intramural • Data Coordinating Center for ~60 multi-center trials • Created centralized clinical trials database • Biostatistics Information Tracking System (BITS) • In continual use for all COH trials since 1989 • Over 500,000 records on more than 20,000 patients • Migrated to MS SQL server, building web interfaces • Also deploying scannable forms

    8. BITS & Clinical Trials On-Line support: >400 clinical trials >110 investigators

    9. Features of BITS • Protocol accessions, demographics, labs, and relapse survival on all patients • Detailed case report form (CRF) data for patients on in-house trials • Export to NCI CDUS application • Mirrored copy of Oacis to import • A2K demographics • Sunquest labs • Cytogenetics • HLA data

    10. Deployed for all Pediatric protocol patients Clinical Pathways System

    11. All Clinical Trial and Observational Study Data Lessons Learned.... • Architecture must support within trial and cross-protocol analyses Study-Specific Model for: Unified Data Model for: T R I A L 1 T R I A L 2 T R I A L 3 T R I A L 4 T R I A L 5 T R I A L 6 Case Series, outcomes research, meta analysis, data mining Case series, outcomes research, meta analysis, data mining

    12. Lessons Learned…. • ‘Metadata’ are critical! • Data about the data themselves • Technical directory: system perspective • Business directory: user perspective • Required for critical database functionality: • Merging in legacy electronic data • Data directory to facilitate data mining • Management of data derivation and logic rules • Preparing summary versions of massive data sets (‘data marts’) • Documenting creation and “sunset” dates of data elements & codes

    13. Creation of an Effective Metadata Repository • Building an interactive Web-based metadata repository (ISO/IEC 11179 compliant) • Will be the “driver” of future systems • Technical metadata populated from ‘feeder’ systems • Detailed analysis of business metadata of all fields underway by full-time Metadata Analyst

    14. Root Cause of Data Managementand Integration Problems • Lack of a unified information architecture • Requires standard • Data model • Vocabularies • Data interfaces • Improved information technology infrastructure and toolsneeded to exploit significant investments in biomedical data • Formidable task • Becomes more intractable and costly as time goes on

    15. FIRST:Fully Integrated ResearchStandards & Technology

    16. FIRST • 3-year GCRC supplement grant funded by the NCRR • Goal: Develop a fully integrated information management and decision support environment • Facilitate all phases of clinical research • Support research infrastructure of the GCRCs • Development group: COH Division of Information Sciences • Input and testing from USC and CHLA • Collaboration with Dr. David Forslund, Advanced Computing Lab, Los Alamos National Laboratory

    17. Objectives of FIRST • Create a clinical research environment to support the wide range of clinical research activities across the protocol life cycle • Bring together enabling technologies: • Standardized information modeling • Object-oriented distributed architecture • Advanced graphical user interfaces • Ultimate goal: scalable interoperable system

    18. caBIG ‘Desiderata’ • Open access, open source • Derived from common information models • Standards for data exchange formats • Data and metadata following ISO/IEC 11179 • Consume appropriate public, open access standards when available All of these principles are being followed in FIRST

    19. Through FIRST… • A common standardized UML model for clinical research will be made publicly available • Semantic analysis will yield common standards and mapping among vocabularies • Integration of existing data sources will be facilitated • Prototype applications that support the clinical research life cycle are being developed and tested

    20. Eligibility Screening Protocol Monitoring Patient Tracking Protocol Tracking Outcomes Data Functionality to be Supported in FIRST Results Research Idea

    21. Principles in Developing FIRST • Computational and semantic standards • Information integration • System interoperability • Workgroup collaboration • Sufficiently flexible methods to: • Scale over time • Adapt to unanticipated needs • Accommodate multiple disease entities • Adopt to different research environments • Exploit major advances in science and technology

    22. FIRST Unifying Information Architecture • Enforce both technological and lexical standards through: • Standardized Data Model • Semantic Standards • Technical Interoperability

    23. FIRST Schematic Diagram

    24. FIRST Modeling Process

    25. Standardized Data Model • Requires clear understanding of the environment • FIRST Advisory Group of senior investigators • Clinical trialists, biostatisticians, research staff, informaticists • Originally envisioned “units of application functionality” as shown in protocol life cycle • Actual components of model far less orderly, organized, and separated in practice • Much time and effort required to: • Separate, document, and specify units of application functionality • Define interrelationships sufficiently begin application development

    27. FIRST Modeling Process • Requirements analysis and documentation conductedin a uniform manner • Unified Modeling Language (UML)-based clinical research domain model • Maintains consistency among model, metadata,and technology • Assures architectural soundness • Improves communication between domain & technical experts • Facilitates translation into an executable program • Promotes platform independence • City of Hope members of HL7 working group • Expert consultant: Gunther Schadow, Regenstrief Institute

    28. Eligibility Filtering Use Case • Use Case 20.0 Protocol Abstraction for Eligibility Filtering • Description • The protocol abstractor entered data about the protocols eligibility and exclusion criteria into the system. • Actor • Protocol Abstractor • System • Pre-Conditions • Protocol is registered into the system. • Basic Course • .The actor has logged into the system (See Use Case 1.0), searched and selected the desired protocol (See Use Case10.0) (example screen # 3) • .The system displays a page (example screen # 4) that allows the actor to select ‘Eligibility Criteria’ within the ‘Protocol Abstraction’ function. • .The system displays the protocol abstraction – eligibility filtering criteria page (example screen #22, #27, #23, #32). The following information is requested about the protocols eligibility and exclusion criteria. All criteria are required. NA is used if the protocol does not specify. • Gender* (^Alternate Course 8.0.3 Add a value to any of the pick lists) • Minimum age and unit* • Maximum age and unit* • Functional status* • Minimum life expectancy* • Disease* • Measurable disease* • Disease status* • Evaluable disease* • Metastases* • Minimum tumor size* • Maximum tumor size*

    33. FIRST Semantic Standards

    34. No Single VocabularyCan Meet All Needs • More than one vocabulary system required for FIRST • SNOMED, LOINC, RX-NORM • caDSR Common Data Elements (CDEs) • External standards can be represented as CDEs (e.g. ICD-O-3) • Still may need to additional terms/concepts • Utilize UMLS to search for terms

    38. FIRST Technologies

    39. FIRST Technologies • Object Management Group (OMG) International Standards Organization • Develops technically integrated, commercially viable, vendor independent specifications for software industry • Achieved international consensus on Common Object Request Broker Architecture (CORBA) • Facilitates technical interoperability among disparate information systems • Recognized as a potential solution in healthcare informatics • Has not been operationalized in clinical research context

    40. FIRST Technologies • Software architecture based on international standards &interoperable components • Leveraging existing standardsor help expand/ build new ones • Systems are “future proof” if retain CORBA-compliant interfaces

    41. OpenEMed (formerly TeleMed) • An intuitive patient-record system that supports, image, audio, and graphical data • Open-source, interoperable components based on OMG Healthcare Domain Taskforce interface standards • Enables multiple databases to be integrated together to create a virtual patient record • Individual healthcare facilities still own and manage their own data • Data accessible to others who have treated the same patient • Security of the data is maintained, patient privacy and confidentiality is ensured

    42. OpenEMed (formerly TeleMed) • CORBA “Services” used in FIRST • PIDS: Person Identification Service • Correlate health records among multiple institutionbased on a "core" set of profile elements, whileprotecting confidentiality • COAS:Clinical Observation Access Service • Interface to supply clinical observations, includingraw data recordings, and derived judgmentsor knowledge

    43.
