Goals of Electronic Health Records from the clinician’s perspective

Remembering what you did and why Conveying that information to colleagues Justifying billing Legal defense Data for research Clinical decision support

Goals of Electronic Health Records from a wider community perspective

• Primary uses: billing, billing, billing ...• Secondary uses

– continuity of care (avoiding siloing of data)– evidence-based medicine– diagnostic decision support– support for clinical trials– virtual clinical research– personalized medicine – (Obamacare) save money

What an EHR requires

• Effective user interfaces

• Trained personnel

• Safety (EHR should help to make your hospital safer; it should not kill your patient)

• Data security

• Controlled vocabulary, and coherent taxonomy (… ontology …)

Where does an EHR fit ?Basic:

Identity

Patient record

Clinician workflow

Comprehensive:

Notifications

Security / access control

EHRs – some alternatives

• Epic, Allscripts, Eclipsys, Cerner ...

• VA

• OpenEHR / CEN 13606

−EHRs for hospitals

−EHRs for small practices (including dentists, ophthalmologists, …)

Epic, Allscripts, Eclipsys ...(Examples of commercial products)

PRO: Get the job done

CON: Expensive

Allow only limited secondary uses

– continuity of care X– safety ?– evidence-based medicine ?– diagnostic decision support ?– clinical trials X

The Data Model That Nearly Killed Me

by Joe Bugajski

http://tiny.cc/S1HWo

“If data cannot be made reliably available across silos in a single EHR, then this data cannot be made reliably available to a huge, heterogeneous collection of networked systems.”

11

EPIC, etc.

will provide a way to capture and represent some of what is needed in a form that is usable

by computers (somewhat)

by you yourself

but not by other clinics, hospitals and researchers ...
