According to the latest count, there are 255 Health Information Exchange (HIE) organizations across the country, which amounts to an average of 5 in each State. If you are a practicing physician and have an EHR, chances are someone already knocked on your door offering to connect your practice to the local HIE for a small fee. If you don’t have an EHR, you may have had offers to access an HIE web portal, or maybe an HIE supplied EHR Lite, allowing you to at the very least view clinical data from other sources. Perhaps for free. If you are the proud owner of one of the full-featured EHRs, you may wonder what an HIE can do for you that your EHR is not already doing, and whether that service is worth your hard earned money.
In theory, a top-shelf EHR should be able to connect your practice to multiple facilities and allow you to exchange information to the best of all participants’ abilities. Granted most EHRs are still working on some of the connections, particularly to local facilities, but all in all, an EHR should be able to eventually provide for all your connectivity needs as shown in Figure 1. Note that for some types of connections, your EHR vendor can use a clearinghouse or portal approach to simplify and reduce costs of connectivity. For example, you don’t need a separate interface for each pharmacy – you use Surescripts as the clearinghouse and let them worry about it. You also don’t need an individual connection to each patient’s home – you communicate with all of them through one portal. With the exception of Surescripts pharmacy connectivity and a small number of reference labs, each connection, or interface, is costing you a pretty penny, and the more local the connection, the longer it takes to build.
