I've been at several teaching hospitals and for the most part everyone is nice and approachable. If you went to a doctor or nurse with a question they'd be more than happy to teach. The only time I've seen nurses dislike doctors or vice versa is when they simply have a poor attitude or bad personality in general... I wish that there was time in medical and nursing education to shadow each other's role more than just seeing a procedure or glimpse of them in the patients room so you can truly see what both providers do. I think it'd result in a lot more respect for both professions.
I do sometimes see a little disrespect toward nurses and I wonder why. From a nurses point of view I don't doubt for a second medicine is a difficult and time consuming job but I think there would be more respect if a physician saw what it was like to take care of 5-6+ patients in a day or night. Student nurses get to see various procedures and surgeries, but not much of what a full day is like and I don't think med students see much at all except nurses scurrying around on the floor or chatting if it's a slow day… I'd love to see a doc at the bedside communicating more with patients, making sure their meds are in on time, making time for wound care and trach care, deliver PRN meds, take care of an ETOH patient who is scoring, administer sliding scale coverage on 5 of your patients, hang several antibiotics, hang blood, 4/6 of your patients have dementia or alzheimers, 1 is sundowning and swinging at you and you can't give your PO meds so you ask the doctor for something to calm them down and they put in an order PO... sprint toward every bed alarm so you prevent patients from falling, meanwhile your other patients are pulling out their IVs/PICCs… and in the back of your head you're saying I need to get all this done on time or ASAP because at any minute one or two of these patients could probably code, and you should've knocked on wood because they just did, and they're 88 years old and should't have been a full code in the first place… I'm not saying all of this happens every night but those are just my examples of some things I usually have to deal with at the same time. It can get busy fast and all of a sudden there is hardly enough time to get it all done.
Anyways, I don't think it's much of a doctors vs nurses thing. I think it's more related to having a terrible personality or being in a crummy hospital environment.
