I’ve been spending a lot of time involved in several Work Groups of the NHIN Direct Project, being run by ONC/HHS. The Project is aimed at developing secure, affordable, health data exchange over the Internet so more physicians can participate in Meaningful Use. This project has major significance to physicians in primary care, to all doctors in small and medium size medical practices, and for many small hospitals, as it is a potential “game changer” with implications for both the EHR technology industry and quality improvement movement. Here’s some background and explanation about why and how.
Background on health data exchange — why paper and fax no longer suffice
As a means of getting information from point A to point B, the fax machine works pretty well. But there are three big problems with faxing health data and information. One, it’s expensive, mostly due to the staff time spent running the machine, changing paper and ink cartridges, and handling paper jams, busy signals, and wrong numbers. Two, faxes contain unstructured text that at best is stored as a document electronically, but usually turns out as paper. Paper is expensive to store compared with digital documents, but the real problem here is that fax data are “non-computable.” Data in a fax is almost always unstructured and therefore unavailable for storage as discrete data elements, e.g. name, address, HbA1c level, etc, in a database. In a database, discrete data can be acted upon by software, but in paper format the data just sits there. And third, faxes are not really secure, as anyone walking by an unattended fax during receive mode can attest.
Not a huge issue, perhaps, until we consider that in 2009-10 Congress and agencies of the federal government have created regulations that require physicians and hospitals participating in the ARRA/HITECH incentives awarded for “meaningful use” of EHR technology to:
- send data to each other for referral and care coordination purposes;
- send their patients alerts and reminders for preventive care;
- offer patients views of their clinical data, such as laboratory results;
- make clinical summaries available to patients after each visit, and: send quality measurement data to CMS.
Given this new situation, which will dramatically increase the flow of data out of medical practices and hospitals, the really pertinent question is this: “If we can’t use fax machines to deliver these messages, what can we use?”
