As a practice I check everyone's mouth. I let the patients know I am an old timer & it makes me feels better to check. They are usually okay with that. For those tricky patients, I keep them on supervision for cheeking for about 1/2 hour after they take their meds. They need to sit with staff. I explain why to the patients and staff. I have even done mouth sweeps which of course my least favorite & last effort to make. It is not all fool proof, but I have less incidents then someone who isn't up front about assuring that they will check for cheeking. When I do checks I really check, not just an "open your mouth," I really look, "tongue up tongue down". I check the paper pill cups too. I document that pt is cheeking, pass it on in report & encourage peers to really check on so & so.
