Project Overview pscanner = patient-centered SCAlable National Network for Effectiveness Research on 21 million patients Goal Implement a distributed architecture to integrate data from three existing networks partnering in PCORnet, and prepare for large-scale, patient centered research with focus on: Weight (10,000) Congestive Heart Failure (10,000) Kawasaki Disease (1,000) Timeline 18 months (April 2014 October 2015) 13
Goals 1. Engage stakeholders at multi-levels of governance Stakeholder Advisory Board (SAB) Governance» Advise on network governance and operations» 10 patients and advocates, clinicians Stakeholder Advisory Board (SAB) Education» Advise on prioritization process, educational materials, and Delphi consensus software» 20 patients and advocates, clinicians Stakeholder Research Prioritization Panel» Online Delphi consensus process» 360 members: 120 patients, 120 clinicians, 120 researchers for 3 cohorts 14
Goals 2. Recruit and survey cohorts Weight (10,000), Congestive Heart Failure (10,000) Kawasaki Disease (1,000) 3. Transform data into a Common Data Model Clinical Data Warehouse formats into OMOP Automated transformation from OMOP into PCORnet CDM 4. Allow pscanner users to query data and build models without patientlevel data leaving the institutions Query Distribution via PopMedNet Statistical analysis tools 15

Tasks for each site OMOP data normalization and harmonization Implementation of a pscanner node Connection of the pscanner node with clinical variables for the 3 CDRN target conditions (weight, CHF, KD) Assist in the recruitment of participants for PCORI-specified patient surveys Provide members to Advisory Board and Stakeholder Panel 17

Weight Cohort Original Case Definition was BMI>30 using the median weights in EHR for 12 months, and at least 1 PCP visit in 24 months Participants: 10,000 Data Elements Clinical lab data Radiology reports Vital signs Pharmacy data (orders, prescriptions) Encounters Procedures Mortality 19
CHF Cohort Case Definition: combination of ICD-9-CM codes in claims and LVEF on Echo. Will use a tool developed within VA that performs cnlp and correctly identifies LVEF measure in text report (98% sensitivity, 100% specificity) Participants: 10,000 Data Elements Clinical lab data Echo Medications Pacemaker device information Co-morbidities (diabetes, atherosclerosis, etc) 20
Kawasaki Disease Case Definition ICD-9 code is insufficient as many cases may be undiagnosed KD is an autoimmune disease that affects many organ systems, most serious issue is coronary artery aneurysm Unknown cause, probably combination of genetic + environmental (? infection) factors limited treatment options, variable efficacy Estimated 2,000-4,000 US cases annually Participants: 1,000 total Data Elements Clinical lab data Echo Medications Vital status (mortality) 21
Federated Query System Centralized query system All the data are aggregated in a single site Federated query system Rather than moving data out of a system to make queries against it, we bring the questions to the data Queries typically result in aggregate numbers SCANNER innovated by allowing distributed analytics: in addition to returning counts, it could return coefficients for global models 22
Beyond Counts User requests data for Quality Improvement or Research Trusted Broker(s) Identity & Trust Management Policy enforcement Clinical Data Network Diverse Healthcare Entities in 3 different states (federal, state, private) How many pa/ents over 65 are on Warfarin or Dabigatran? What are the major and minor bleeding rates for pa/ents on these drugs, adjusted for co- morbidi/es? Can we predict the chance of complica/ons? Kim K et al.
