The Health e-IT Act of 2008 has many interesting proposals. Of note, is the charge to ONC to create an Open Source EMR to be completed 9 months from the completion of requirements(page 18)PDF text of bill here.
On page 41 the act calls for NIST to create a standard and certification process for EMRs.
By my stopwatch, it’s been around 11 years since it was obvious that an Open Source EMR to rule them all was the way to go. Nice to see the goverment actually catch on.
