So far in this series I’ve attempted to lay the groundwork to give you a basic understanding of Health Information Exchanges. Now that we’ve defined the What and the Why, this post will discuss How health organizations actually exchange health data with the HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical...

  • Secure FTP
  • Secure E-mail

I’ll describe each communication method, from most interoperable to least interoperable.

TCP/IPTransmission Control Protocol/Internet Protocol (TCP/IP) is a low-level communications protocol used... More over VPN

TCP = Transmission Control Protocol
IP = Internet Protocol
VPN =  Virtual Private Network

This model allows computers to communicate over a secure private network and provides end-to-end connectivity, with specifications on how data should be formatted, addressed, transmitted, routed and received at the destination. This method is the most-connected (interoperable) way to exchange health data in an HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More.

More documents are immediately transmitted to the HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More based on trigger events at the point of care, such as a patient discharge. This consecutive updating of a patient’s data gives all HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More members access to a patient’s current health record.

At Corepoint Health, we would obviously encourage health organizations to use an integration engine to connect to a public HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical...

Integration engines eliminate the need for extensive point-to-point scripting/programming to configure messages containing CCDContinuity of Care Document (CCD) The HL7 CCD is the result of a collaborative effort between the He...

Secured FTP

FTP = File Transfer Protocol

Organizations connecting to an HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More via secured FTP can send patient data in batches, or one document at a time.  Batches are typically sent once each day. This obviously is not a real-time HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More solution, but it does enable the sharing of patient data, thus meeting Meaningful Use electronic data exchange requirements as specified in Stage 1.

Secure E-mail

Utilized as an entry-level communication method for HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More involvement, secure e-mail is the direct transmission of one provider’s patient data to another requesting HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More provider, via secure e-mail. Frequently called the “push” method of HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More data exchange because the owner of the information “pushes” the data to another location.

Typically, this is how the exchange works: Provider A contacts the HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More requesting to find information about a specific patient. The HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More might have a portal that returns locations (other HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More providers) that have information on the specific patient. Provider A will then request that patient’s information directly from the providers identified by the HIEHealth Information Exchange (HIE) focuses on the mobilization of healthcare information electronical... More. Once the request is received by the other providers, they will securely email the data to Provider A.
