Electronic patient records have been implemented since... about... 2004 in the UK. It would be almost impossible to find a hospital in the UK which hasn't got EPR in some form (it's upto each individual hospital to choose what exactly they want to implement). Some hospitals have been through 2 or 3 different software brands in that time. Some hospitals are already completely "paperless"; which means all notes should be kept on computer and any new paper gets scanned and then shredded. Pretty much every family physician (GP) in the UK has electronic records too.
Your question is like 2 decades behind the times. Of course it's a good idea.
Why on earth are you reading about EPR/EHR/EPR? Boring AF!
