As a patient, in the past I've absolutely been directed to ice injuries for weeks. (Not so much in the last ~10 years, as the world caught up to the fact that this was a bad idea.) Sources like the Red Cross or WebMD article on RICE[0] _still_ recommend it for at least 48 hours after a minor injury, even though this has been debunked.

So I think it's good that the Wikipedia article emphasizes that the protocol is outdated.

Last time I had anything like that (tooth removal) they said two hours tops, after that it won't make much of a difference for the swelling anymore.

I had a knee injury just this February and I was instructed to cool my knee with ice for weeks (I don't think they meant it constantly - but at least from time to time).
