“It is the responsibility of those of us involved in today’s biomedical research enterprise to translate the remarkable scientific innovations we are witnessing into health gains for the nation.”
Clinical and Translational Science AwardsA NIH Roadmap Initiative
• Administrative bottlenecks• Poor integration of translational resources• Delay in the completion of clinical studies• Difficulties in human subject recruitment• Little investment in methodologic research• Insufficient bi-directional information flow• Increasingly complex resources needed• Inadequate models of human disease• Reduced financial margins • Difficulty recruiting, training, mentoring scientists
Background: Dan MasysNIH Goal to Reduce Barriers to Research
CTSA Objectives:
The purpose of this initiative is to assist institutions to forge a uniquely transformative, novel, and integrative academic home for Clinical and Translational Science that has the consolidated resources to:
1) captivate, advance, and nurture a cadre of well-trained multi- and inter-disciplinary investigators and research teams;
2) create an incubator for innovative research tools and information technologies; and
3) synergize multi-disciplinary and inter-disciplinary clinical and translational research and researchers to catalyze the application of new knowledge and techniques to clinical practice at the front lines of patient care.

Gap!
Existing KUMC 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. Capture Adverse Events, Reports, Export Data for analysis. Options: Samples, Financials, Regulatory IRB
Other Approaches OnCore by Forte Research Systems – more expensive,
highly customized for Cancer Centers…. Ferrari to Velos’ Audi.
RedCap by Paul Harris at Vanderbilt University – “free but not open source”, capabilities growing. Implementing at KUMC for registries. Think Hyundai

CRIS: sample e Case Report Form
CRIS: Document Adverse Events
KUMC CTSA Specific Aims1. 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 HERON/i2b2, CRIS, Redcap, biorepository, etc.
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 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 re-identification risk.

HERON to evaluate clinical research in rural settings
Timeline: Existing Projects, Aims 1 and 2
Timeline: Aims 3 and 4, Team Growth
Team Roles & Size Estimates “The Data Warehouse Lifecycle Toolkit” by Ralph
Kimball. Identifies 15 Roles. Informatician (leader, architect, project mgt) Database Administrator/Technical coordinator Software Engineers
Extract, Load, Transform (ELT/ETL) - SE or DBA Modify/augment systems (DB and i2b2)
Estimate 3 FTE for HERON slower technical build and maintain.
CRIS/Redcap team 2-4 people fractionally
Team continued and other “costs” Hardware ~$20-30k initial. ~$5k annual IT infrastructure from KUMC Information Resources:
Sys Admin, Network, Security, virtual servers, DBA and OS consults.
Clinical/operational partner’s technical time Legal time: Shelley Gebar estimate (also partners) Governance time commitment for committees
Executives: quarterly 9 $$$$ people Data Request Oversight: monthly? 10 $$$ people
Analyst, terminologist, customer liaison: to be hired, estimate 0.7 FTE
Guesses for Wichita to go Fishing Roll your own. Necessary for me to build an academic
informatics research effort. May not be necessary for Wichita. Hire a consultant like Recombinant to do i2b2 or use a
consultant for a commercial package (variety of vendors) Partner institutions create infrastructure and fish in their ponds Hire KUMC team to support Wichita. Similar to Vanderbilt
building the RHIO for Memphis (see Mark Frisse and Midsouth eHealth Alliance http://www.midsoutheha.org/)
Wait for HIE to happen. Piggyback on RHIO capabilities. Fish in Medicaid or AAMC, DARTNet ponds. Fish in KUMC/KUH/UKP pond.
