Query Health Concept Mapping Activity

1. Query HealthConcept Mapping Activity

2. Overview • A (very basic) background on concept mapping • The problem that the Concept Mapping workstream is trying to solve • Five questions for you • Any questions for us and general discussion

3. Background • The majority of healthcare systems maintain their own dictionaries • The terms in these dictionaries are not compatible with others • ‘PA/Lateral CXR’ vs. ‘2-view chest x-ray’ • In order to speak the same ‘language’, we have to: • Agree on the same language • Translate what we say into this agreed upon language • Translate what we hear back into our own language • This translation exercise is what is termed ‘concept mapping’

5. Concept Mapping Illustrated • Other Code Set • Code 1 • Code 2 • LOINC • Code 624-7 • Code 6460-0 Clinical Concepts • SNOMED CT • Code DE-14213 • Code DE-10100 Map Vocabulary Codes ↔ Concept Dictionary • ICD 9 • Code 486.00 • Code 481.00 UMLS, etc. • ICD 10 • Code J 18.9 • Code J 18.1

6. The Importance of Concept Mapping… and the problem at hand • Query Health will disseminate queries to many data sources • It is unlikely that any of these data sources will understand that format natively • Each data source will have to map their own concept dictionary to the concepts expressed by the query • Some larger organizations and information exchanges may already have mappings to standard vocabularies, but many others may not • In order to ease the burden of participating in Query Health, how can we facilitate the concept mapping exercise?

7. Where the Concept Mapping Activity comes in • As part of the Query Health initiative, we suggest undertaking work to discover the best practices in concept mapping • The ultimate goal of this effort would be a guide describing these best practices Question 1 Should we undertake this work?

8. Question 2 How should we do this study? • Semi-structured interviews • Structured survey • Focused group discussions • Literature Review • Another methodology

9. Question 3 If we use a methodology that collects information from experts (surveys, interviews, FGDs), who should we target? • Information Exchange Implementers • Creators of tools to facilitate mapping (i.e. RELMA for LOINC) • Other groups? From which organizations?

10. Question 4 If we perform a literature review, what terms should we include? • AND Mapping • AND (LOINC or SNOMED or SNOMED-CT or ICD-9 or ICD-10 or ICD-9-CM or ICD-10-CM or ICD-10-PCS or RxNorm or CPT) • Other terms

11. Question 5 How should we (your support team) proceed before the activity starts in 3-4 weeks? • Do nothing; all work from study design onward should be in the Concept Mapping workstream • Have the Implementation workgroup approve a study design and the support team should begin collecting data; all data analysis should be done in the Concept Mapping workstream • Have the Implementation workgroup approve the study design and the support team should collect data and analyze it; the Concept Mapping workstream can review the analysis • Another approach
