I don't think that's the case. AFAIK there's no such system. The article specifically reference Epic, which is one of the biggest (_the_ biggest?) EHR software company in the US. My wife used it as a nurse and I've watched my own providers struggle with it. It sucks.
Indeed. The biggest hospital where I live (Trondheim, Norway) is still running at reduced capacity and over budget a year after moving to an Epic derivative. Doctors and nurses are burning out, many talking about moving elsewhere. Being recently retired, I am concerned that this may not be a safe place to grow old, if the hospital (by all accounts an excellent one) is dragged down by this horror of a system.
Saying “it sucks” is like saying “SAP sucks”. Whatever system you get out of one of these projects is 99% dependent on the project team (on both sides), and 1% on the product base, which is invariably “meh”
