Harvard Catalyst SHRINE October 13, 2010 Douglas MacFadden & Andrew McMurry catalyst.harvard.edu cbmi.med.harvard.edu Created with the support of Harvard Catalyst | The Harvard Clinical and Translational Science Center (NIH Grant #1 UL1 RR 025758-01 and financial contributions from Harvard University and participating academic health care centers). Foundational Work • I2b2 - Clinical Data Repository – Zak Kohane, Shawn Murphy et al. – Turning everyday clinical encounters into huge research cohorts – Star-schema database with associated ontology – JavaScript Web Client (Griffin Weber) • SPIN - cross hospital query model – Andy McMurry et al. – Federated query of autonomous/independent hospitals – Abstract away the differences of each data repository enabling on the fly query translation Harvard Catalyst SHRINE Objective • Query Clinical Data Across Multiple Harvard Teaching Hospitals – Increase Data Set Size – Demonstrate Cooperation Across Competing Institutions – Develop Data Sharing Infrastructure Architecture I2b2 features leveraged for SHRINE Webclient, Project Management, Ontology, Data Repository I2b2 features leveraged for SHRINE: Webclient 1. Webclient speaks to the broadcaster aggregator as if it were another i2b2 Clinical Data Repository 2. Minor enhancements to support additional auditing/monitoring of SHRINE queries Griffin Weber, Nicholas Benik I2b2 features leveraged for SHRINE: Project Management Cell 1. Authenticate local investigators 2. Pointers to “Cells in the Hive” Location for the Ontology Location of the Data Repository URLs for all i2b2 cells I2b2 features leveraged for SHRINE: Ontology Cell Handles deep “nested” hierarchies like Diagnoses\Neoplasms\Cancer of breast 1. Demographics • Age • Gender • Language • Marital Status • Religion • Race and Ethnicity 2. Diagnoses - HL7 Administrative Gender - ISO 639-1 - HL7 Marital Status - HL7 Religious Affiliation - CDC Race & Ethnicity Code Sets - ICD-9-CM and CCS hierarchy 3. Medications - RxNorm and NDF-RT hierarchy 4. Lab Tests (demo) - LOINC I2b2 features leveraged for SHRINE: Data Repository Cell Star Schema design concurrently supports multiple ontologies (local ontology and SHRINE ontology) SHRINE works with CRC v1.3 and v1.4 Use your existing i2b2 deployment, no code or data changes required! Shawn Murphy et al. Challenges • Organizational • Informatics • Usability Challenges: Organizational • Ground rules: contribute data to play, all users must “belong” to participating institutions • Regulatory Buy In • Management Buy In • Controls – Query Topics – User Agreement – Audit Trails • Consequences for Bad Behavior Challenges: Informatics • Implement Local Data Warehouse and ETL from Operational Systems • Server/Network security • Design and Development of Core Ontology • Perform Local Mapping to Core Ontology • Implementation of Network and Systems at each Site • Implement Required Controls • Prevent Re-identification Challenges: Usability • • • • Ease of Access Easy Query Creation Understanding of Query Results Understanding the Limitations of Data Coding from Operational Systems Phase 1 6MPatients 1B Facts 4 Ontology Categories, 18K Terms 10K Potential Users 4 IRBs 4 major competing hospitals, 3 sites Partners Health Care (BWH, MGH) Children’s Hospital Boston Beth Israel Deaconess Medical Center SHRINE queries (Actual Patient Counts) • Comorbidity of Breast and Cervical Cancers • Acute Myocardial Infarction with Gender Breakdown • Pediatric Rhematoid Arthritis (rare) • Countless more secondary uses of electronic medical records… Where We Are Today • Now: – Second Round of Beta Test – 1.7 + Saved Query – Expanding to include Dana Farber • Plan: – SHRINE 2.0 – Limited Data Sets • Opportunity: – Regional and National Networks Regional and National Networks 1. Agree to a common policy/understanding for all sites 2. Implement i2b2 platform & SHRINE technology 3. Develop local Ontology mappings 4. Implement network security infrastructure 5.
