Can we end multiple copies of patient letters?

Next frustration… Multiple copies of the same patient letter. Sometimes I get a photocopy delivered by hand or posted to me, or the patient sends their copy of a letter. Sometimes these come in over a period of days and they all end up in my inbox needing to be read and/or actioned. Worse if they arrive on days when I’m not in, someone else has to action them – at least I might remember I’ve seen it before. So three doctors reading and actioning the same letter!

Why can’t each letter produced by a Trust have a UUID on it that IDs it and my document software recognizes this and says… oh you’ve had this before??
