One thing that really irks me when I'm talking to a patient is cell phone use. I can count the number of times on one hand that I have had to take a phone call while talking to a patient. They were true emergencies: ICU calling about a patient I'd been watching, call from another hospital about a transfer, that sort of thing. Whenever it has happened I have apologized profusely and walked out of the room to take the phone call.
One afternoon, as I was making my rounds, I walked into the room of man admitted for pancreatitis. He began his conversation with me about his progress and we were discussing his treatment when his phone rang. He immediately picked up the phone and started talking on it, like I wasn't even there. I continued to ask him questions, which he would answer very curtly and with single-word answers. I finally got sick of it and walked out of the room. About 30 minutes later, I got a call from nursing about the man.
Nurse: "Mr. Cell Phone forgot to ask you for something, he wanted to know if we could increase his pain meds."
Me: "Tell him I have to take a phone call and I'll think about it."
I never called back.
