Yeah, the problem with introducing any safety procedure is that if you have to do it a thousand times a day, it eventually becomes mentally automated. It's like clicking "I agree" to EULAs, or "let this program access to the Internet" on one of those versions of Windows that would incessantly ask you whether you wanted to let a program access the Internet (never had one, but heard awful things from people who did).

I've never used a program like that, so I don't know whether the bar for alerts is set high enough that most alerts will be real errors, or whether it gets into so many nitpicky things (you're using an antihypertensive with another antihypertensive! What if that causes hypotension?!) that you eventually develop a reflex of clicking through them. I'd hope the former.
