And even within that single country, each state and hospital then has their own requirements around EHRs. This ends up being my biggest issue with EHR is that you need to support infinite flexibility for all the unique snowflakes that exist. I'm convinced healthcare would improve in this country if the federal government standardized all of this to a single setup. This also includes the mess that is EHR in EMS.
Part of EHR's problems are definitely that the market is only one single country, the United States.
