4Order Sets Project Goals By sharing evidence-based order sets (EBOS) among member hospitalsImprove child health care by decreasing unfounded variability of practiceIncrease speed and decrease cost of implementation of evidence-based orders sets in EHRs
5Milestones and Activities Establish Project governance to define, implement, and evaluate project goals.Establish an evidence-based order set (EBOS) Library, with basic rules for submission, from pilot hospitals.Define basic rules for EBOS submissions, including statement of order set development at the submitting institution. EBOS should include (1) set descriptors; (2) inclusion/exclusion criteria; (3) care process with associated evidence; (4) outcome measuresCreate a standard format for EBOS in the Library.Populate and evaluate initial candidate EBOS, using the standard format.Validate effort with CHCA Governance and member hospitalsExpand effort as appropriateDon’t know if this is helpful and we don’t want to read to them. We need to solicit agreement on what will occur during each timeframe as to who does what and what is to be done for each step. Perhaps use more of a bulleted or grid approach to help them see and reach agreement might be more helpful. Run by Gary as he spoke to Gretchen.***I am not sold on these next three slides. This information is mostly contained on slide #11. I tried condensing information and bulleting it, but I am open to another approach.

8CARRANet $8+M GO grant ; PIs: Sandborg, Schanberg, Ilowite, Wallace Sustainable, informatics infrastructure for pediatric rheumatologyTo enroll 60 sitesTo enroll 20,000 children with rheumatic diseaseRegistry with common and disease-specific data elements
9Informatics Infrastructure CARRANet Centralized, web-based data captureData management, visualization, and cleaning tools to facilitate site-based and pooled data validationCentralized, ontology-based, centralized,database environment (i2b2/SHRINE) with site-specific PHI encryption and data ownership, designed for secure, selective sharing and federated query of research dataMeans to correlate data from samples housed in the CARRA biorepository with subject-level phenotypic data stored in the distributed database.
12Concepts and Definitions … Be Careful What You Ask. You May Get Another Answer.Medication Inclusion: Pulse steroids? GA BA-directed? Opioids?Use for rheumatologic disease, or any purpose ?Prescribed only ?Current – actually taken today; prescribed for today; if oral, taken today without emesis; taken anytime in last x days; majority or all of doses taken in last x days ? Is a PRN medication (e.g. ibuprofen for fever) a “current” medication ?Unknown – to whom? Not in record ?
13Ambiguity Threatens Value CHIPRA and Meaningful Use Quality Measure: Immunizations Is the question: educate, recommend and/or give an immunization ?Are all immunization data available at the time of care to make the appropriate decision ? Transient populations ?Vaccine guidelines change. Is quality determined by action based on guidelines applicable at the time of the encounter ?Is appropriateness dependent on circumstance ? If a child is admitted to hospital, and rapidly transferred elsewhere for intensive care, should vaccination have been done ?What if provider practices in a religious community refusing vaccinations?What if patient is “immunosuppressed” by condition or medication ?
14What’s the Source of Truth ? Each provider and patient ? Then nobody else is really sure what the truth is …Existing and evolving standard terminologies: e.g. LOINC, RxNorm, ICD, SNOMED … (but they only describe “elements,” not relationships)Institutional ontologiesCollaborative ontologiesInternal EHR ontologies – Centricity, Epic …“Meta”-EHR ontology – openEHR ?
15American College of Rheumatology (ACR) Concept Mapping
16Goals (my take)Build a Rheumatology functional profile, with rigorously defined data elements:begin with identification of data elements, within constructs such as “musculoskeletal exam” and “drug monitoring”Utilize UML (Unified Modeling Language) based mind mapping software and openEHR, so that specifics can be “rapidly” translated to multiple commercial systemsProvide the basis for a “universal translator” (a multifaceted rosetta stone) of critical rheumatology data from multiple different systems and sites, into common terminology for collaborative QI and research efforts
17OpenEHR (ISO 18308) Archetype: Re-usable, versioned, formal model of a clinical domainStandardized formatMaximal datasetConsider using archetypes as basis for CDA entries, with SNOMED identifiers for each archetypeTemplate:Structured compilation of archetypes for specific purpose – e.g. basis of documents, forms, reports, messages
18OpenEHR Ontological Separation Ontologies of information:Domain content models – formal definitions of clinical concepts (archetypes)Information representation model – basis for domain content model, designed to be stableOntologies of reality:“Classifications” like WHO’s ICPC (International Classification of Primary Care)“Process descriptions” such as clinical guidelines“Descriptive” terminologies” like SNOMED-CT, RxNorm, ICD

24Back to the Future National pediatric data lexicon and concepts Shared evidence-based guidelines and order sets with defined eligibility criteria and outcomes, e.g. CHCA and EpicNational, broad scope, pediatric clinical (research) data network(s) that really work, are sustainableGoals:Support clinical research and care, dynamically refining care parameters cross institutionsIdentify “new” pediatric diseases: a human phenome project
