It's also not hard to do casually without having to grovel. My nursing subspecialty is violence management and I frequently respond to things with,"thank you for reminding me, I'm going to go do that now!" and,"I hadn't realized that was your preference, thank you for letting me know!" or,"that's a good thing to point out I'm glad you're being an active participant in your care!" You don't even have to say you're wrong half the time you can also just regularly tell people they're right.
