Epic isn't new, just new to Ireland. Hospitals and other healthcare in the US use this system already, hence the "made it to ireland"
It sucks shit. It's slow, lacks the ability to attach meaningful Notes for the next person that searches a patient, nursing staff often don't update it so family looking for them have to call floors anyway (because part of the point of attaching a room is to speed up visitation), descriptions of ORs and Surgery is so vague noone knows where the fuck a patient is if not in a room. (Kinda like a usps package!). Charting with it is difficult. But that's just the opinion of some random nobody on the internet.
