At the hospital when the nurse is talking to Frasier discussing what happened, she is having trouble with a sheet of paper on her clipboard. In the next shot the sheet has gone completely.
A patient's diagnosis and any story associated with a visit to the hospital would never be discussed in an open room full of people. Ever.
About 15 minutes into the show, when Ronee comes over to see Martin, she says her line to Martin that ends with, "...like she's a hundred," and then turns to look at Frasier and Niles. When the camera cuts to show Frasier and Niles, you can see Ronee mouthing the same words again with no audio, "...like she's a hundred." Ronee is to the right in the shot.
