A friend of mine named Jane works as an attending supervising residents in a clinic. After the residents see the patients with Jane (or whatever attending is supervising), Jane signs off on the resident note and returns the chart to them.
One resident apparently thought that the attendings were not reading their notes. So he devised a note about a patient named Tabby. Tabby was a cat whose chief complaint was a hairball.
One day in clinic, this resident handed his note about Tabby the Cat to Jane, who signed the note. The resident then circulated the fake note to all his resident buddies as proof that he was right.
Of course, the note got back to Jane's supervisor and she got a note in her file.
Honestly, I'm sympathetic to Jane. Sure, she didn't read the resident's note. But who suspects that after the resident presents the patient to you that they're going to write something so entirely different? How many attendings truly read resident notes that carefully?
