Cross cover is always a sticky situation. You're dealing with patients you don't know and sometimes have to make important decisions about them. I feel like if it's at all possible to defer those decisions to the regular team, that's what should happen. I feel like the only things that should be changed during cross cover are potentially life threatening medications.
Other people feel differently. Here's a snippet from a cross cover I did a while back:
Nurse: "Doctor, Mrs. Chang is getting qAC fingersticks but her daughter doesn't want her to have them. I think she's only getting them because she wasn't eating before but now she is."
Me: "Is she diabetic?"
Me: [checks sign-out sheet from primary team to make sure pt isn't diabetic] "And she's tolerating her diet?"
Me: "OK, you can D/C the fingersticks."
Nurse: "Also, Mrs. Chang is written for morphine PRN, but her daughter doesn't want her to have it."
Me: "Uh ok.... well, it's PRN, so what's the problem?"
Nurse: "Can I D/C the morphine?"
Me: "But it's PRN. She doesn't have to take it."
Nurse: "Then I'll D/C it."
Me: [getting paged again] "Fine, whatever."
The next morning, the resident on Mrs. Chang's primary team comes up to me: "Why did you D/C Mrs. Chang's fingersticks? She's diabetic!"
And then he got mad at me for having D/C'd the PRN morphine.
(Here's a tip: If a patient is diabetic and you want them to stay on qAC fingersticks, maybe write that they're diabetic on the signout sheet.)
