Validated solutions more likely to scale. Data sharing involves multiple organizations KUMC Opportunities Quality Focused Hospital Without every solution involving informatics Prior CTSA goal: Data “Warehouse” Advance research and clinical quality “Green Field” for newer technologies State and Region KUMC strong in community outreach research Link our data to external information? (Ex: KHPA Medicaid data) Health Information Exchange “window” KU-Lawrence Researchers, Cerner, Stowers Institute Existing Teams Clinical Research & Medical Informatics CRIS: Comprehensive Research Information System Team New Medical Informatics plus KUMC Information Resources critical contributors for infrastructure Bioinformatics K-INBRE Bioinformatics Core Center for Bioinformatics and Engineering School Dr. Gerry Lushington Center for Health Informatics World Class Telemedicine Leading Health Information Exchange for the State Terminology, Training, Simulation Expertise Dr. Judith Warren Clinical Research Information Systems KUMC has purchased Velos eResearch and calls it “CRIS” Define Studies, Assign Patients to Studies Design and Capture data on electronic Case Report Forms (CRFs) – ideally in real time.

Think Hyundai CRIS Intro Screen CRIS: sample e Case Report Form CRIS: Document Adverse Events KUMC CTSA Specific Aims 1. Provide a HICTR portal for investigators to access clinical and translational research resources, track usage and outcomes, and provide informatics consultative services. 2. Create a platform, HERON (Healthcare Enterprise Repository for Ontological Narration), to integrate clinical and biomedical data for translational research. 3. Advance medical innovation by linking biological tissues to clinical phenotype and the pharmacokinetic and pharmacodynamic data generated by research cores in phase I and II clinical trials (addressing T1 translational research). 4. Leverage an active, engaged statewide telemedicine and Health Information Exchange (HIE) effort to enable community based translational research (addressing T2 translational research). Aim #1: Create a Portal and Consult Bring together existing resources Translational Technologies Resource Center Link to national resources www.vivo.org – Facebook for researchers www.eagle-i.org – National resources (rodents, RNAi, to patient registries) Develop tools to measure and track our investment Pilot funding requests, electronic Institutional Review Board process Provide a hands on informatics consult service Also organize existing resources Portal: Access + Measurement Aim #2: Create a data “fishing” platform Develop business agreements, policies, data use agreements and oversight. Implement open source NIH funded (i.e. i2b2) initiatives for accessing data. Transform data into information using the NLM UMLS Metathesaurus as our vocabulary source. Link clinical data sources to enhance their research utility. Develop business agreements, policies, data use agreements and oversight. September 6, 2010 the hospital, clinics and university signed a master data sharing agreement to create the repository. Four Uses: After signing a system access agreement, cohort identification queries and view-only access is allowed but logged and audited Requests for de-identified patient data, while not deemed human subjects research, are reviewed. Identified data requests require approval by the Institutional Review Board prior to data request review. Medical informatics will generate the data set for the investigator. Contact information from the HICTR Participant Registry have their study request and contact letters reviewed by the Participant and Clinical Interactions Resources Program Constructing a Research Repository: Ethical and Regulatory Concerns Who “owns” the data? Doctor, Clinic/Hospital, Insurer, State, Researcher… perhaps the Patient? Perception/reality is often the organization that paid for the system owns the data. My opinion: we are custodians of the data, each role has rights and responsibilities Regulatory Sources: Health Insurance Portability and Accountability Act (HIPAA) Human Subjects Research Research depends on Trust which depends on Ethical Behavior and Competence Goals: Protect Patient Privacy (preserve Anonymity), Growing Topic: Quanitifying Re-identification risk. Re-identification Risk Example Will the released columns in combination with publicly available data re-identify individuals? What if the released columns were combined with other items which “may be known”? Sensitive columns, diagnoses or very unique individuals? New measures to quantify reidentification risk.

Providing coded pathology results and patient diagnosis is a critical objective for defining cancer study cohorts in Aim 3. Clinical narrative 2012 National Center for Biological Ontology 2013 As hospital restructures clinical narrative documentation to use EPIC’s SmartData (CUI) concepts, will determine appropriate standard. In support of Aim 3 focus on bridging clinical and bioinformatics to advance novel methods. Link clinical data sources to enhance their research utility.

PK/PD should be the most common research analysis for phase 1 trials. Third focus: Apply molecular bioinformatics methods to enhance T1 translational research in areas such as molecular biomarker discovery efforts and pharmaceutical lead optimization Also promote clinical domains for Lawrence researchers Aim #4: Leverage telemedicine and Health Information Exchange (HIE) for community based translational research The HITECH Act and “meaningful use” are a landmark event for Biomedical Informatics and Health Information Technology State Health Information Exchanges Regional Extension Centers Incentives (then penalties) for Providers Provide health informatics leadership to ensure state and regional healthcare information exchange (HIE) and health information technology initiatives foster translational research Dr. Connors chaired the formation Kansas Health Information Exchange Drs.
