## Intermountain Healthcare Clinical Genetics Institute Marc S. Williams, M.D.DirectorGrant M. WoodSenior IT Strategist

- Introduction to HL7 Clinical Genomics

## Informatics Line in our Brochure

- Link genomic/family medical history data to the electronic medical record to provide advanced genetics-based tools for the clinician.

## Genomics and Informatics

- Clinical genomics data could dwarf the data storage and management challenges posed by genome sequencing projects.
- Personalized medicine will require an increased integration of clinical and research databases.

## Health Level Seven (HL7) Overview

- HL7 is an international community of healthcare clinical and informatics experts collaborating to create standards of electronic healthcare information
- The organization is comprised of Technical Committees (like Clinical Decision Support, Electronic Health Records,  Medical Records, etc) and Special Interest Groups (like Clinical Genomics)
- Develop standards that permit structured, encoded health care information, to be exchanged between computer applications
- Collaborate with other standards development organizations
- Encourage organizations to participate in HL7 to develop healthcare information standards in their area of expertise
- Collaborate with healthcare information technology users to ensure that HL7 standards meet real-world requirements

## HL7 Clinical Genomics

-  Lead model developer is Amnon Shabo from the IBM Haifa Research Lab
- Other participants include representatives from healthcare provider, pharmaceutical, software vendor, professional services, and Veterans Administration
- Genetic Locus, Genetic Loci, and Family History models approved via ballot as Draft Standard for Trial Use
- Model is designed to store genomic data in the EHR for use by clinical decision support applications
- Waiting for implementation by early adopters and partners to test the exchange of clinical genomic and family history data

## Incorporation of CG data into the EHR

**Longitudinal Patient EHR**
**(RIM-based CEN 13606 EHR)**

**A Clinical Genomics Instance**

**Don’t leave behind the raw genomic data...**
**bring it into the EHR!**

## The Underlying Paradigm: Encapsulate & Bubble-up

**Clinical Guidance**

**Patient    Genotype**

**EHR System**

**HL7 CG Messages **
**Encapsulating HL7 Objects**

**HL7 CG messages associated with HL7 clinical objects (phenotypes – Warfarin metabolism)**

**Bubble up the most clinically-significant raw **
**genomic data into specialized HL7 objects and **
**link them with clinical data from the patient EHR**** **

**Decision Support Applications**

**Knowledge**
**(KBs, Ontologies, registries, **
**reference DBs, Papers, etc.)**

**Bridging is the challenge...**

**Encapsulation of CYP2C9 and VKORC1 sequence data**

**Evidence-based algorithm to determine starting dose**

## American Health Information Community Workgroups

- The EHR Workgroup has identified ten priorities that represent essential minimum features or functions of EHRs. These features or functions are the utilities identified as the most important clinical data elements by clinicians who are either considering adoption of EHRs, or those who have adopted but desire interoperability in these areas. These utilities are noted in priority order as determined by the EHR Workgroup, and are all considered critical for comprehensive patient care.

**Patient Identification**
**Medication List / Allergy**
**Laboratory Results**
**Problem List**
**Clinical / Encounter Notes**
**Anatomic Pathology Results**
**Vital Signs**
**Family History/ Health Factors**
**Radiology Reports: Not including images**
**Immunizations**

**8.  Family History/ Health Factors:**** **May contain a detailed problem list and health history of a patient’s family members. Typically used by providers when assessing familial risk and planning care.

## Implementations

- Family History
- Massachusetts General Hospital
- Fully based on the v3 models
- Incorporating genomic information into the patient EHR
- Partners HealthCare – Structured reporting of sequencing based genetic tests
- Clinical decision support rules to leverage genetic tests results
- Genetic testing information exchange
- Harvard HPCGG and Intermountain Health Care
- Map to HL7 v2 lab messages that are currently supported by existing lab systems on both sides
