I saw this article called background: US policy for EHR that attempts to give a background on how the EHR landscape took shape starting from the stimulus dollar to the new standard that is currently being created.
The standards adopted in the IFR cover four main areas: Vocabulary- promotes the creation of a common language and codes to be applied in clinical problems and procedures; Content Exchange- setting guidelines to be followed when sharing information; Transport- for systems and processes which will transport information between healthcare systems; Privacy and Security- authentication and transmission security for safe handling of patient information.
Here is my perspective on each one:
1. Vocabulary. The standardization of vocabulary will be the key with the first and foremost the standardization of drug codes. Currently the government has a generic set of drug codes called RxNorm. However, RxNorm is rarely mapped in EHR systems. This will have to change in order to provide better information exchange.
2. Content Exchange – Currently one of the way to exchange data is the HL7 standard. As someone who works closely with HL7, it doesn’t exchange data that easily. In order to facilitate content exchange, there need to be a way to create a master data management. How do we know one patient in one EHR system is the same as another patient in another EHR system?
3. Transports – nothing comment on this one. However, if we can create an infrastructure like the one Google is currently proposing (100 gig) it will definitely help data exchange and transports.
4. Privacy and Security – This will be a huge issue. With the amount of data that can be stored on an external storage these days, it is very easy to get information leaked.
