Sandeep, from what you see of AC and its construction, what happens if we are totally happy with what we have, and never do another upgrade? Ignore MU requirements, ICD-10, etc..... assume we can patch around them. Is there some connection to AC that HAS to be maintained, or could we just continue to enter chart notes and if need be manually code and prescribe if our relationship with AC totally dissolved?
AC does phone home every so often to verify the practice. Some of us have seen how slow it can get with the Internet down and no prescription writing abilities. However, they cannot take the software away from you. Everyone here has purchased the license for the software. The support is separate and renews annually. Even in the cloud, you own that version of the product. Most other EMR companies will not give you rights to the EMR software so you can never own it. But like all activation, it can be circumvented by people with the right skills. Just ask Adobe and Microsoft who spend hefty sums of money implementing sophisticated activation measures. If it comes to that, people will be ready.
