As a pharmacy student, I guess I'm a little more like a third party, but I just had to respond to this. From my observations, you are RIGHT ON!! This isn't a problem that just nurses have with doctors; all the other health professionals have the same issues with MD's. Whatever happened to the supposed "interdisciplinary team" that we're all supposed to be working in? This, of course, is not true of all doctors, but it does make us truly appreciate the ones who treat all us other health professionals with respect.
I'm really glad I have the experience of working as a pharmacy technician in a very busy pharmacy. The rural township (its small but there is a large percentage elderly population + a university of 13,500 students) gives me great insight. For instance, since there are not many docs in town, our pharmacy knows all of them. My boss has been a pharmacist in the area for about 25 years now and has developed, good or bad, a relationship with all of the doctors. I have another coworker pharmacist (actually he is technically my boss too) who is only 7 years older than me and fresh out of school with a Pharm.D (all of our other pharmacists are older, from the B.S. crowd). Now heres two points I want to make...
The older MDs here in town are extremely condescending towards the pharmacists I work for. They get irritable anytime they are called to clarify a mistake on a prescription (today, one doctor wrote for "Tramtrine 30-5"... no one knows what the hell that's supposed to mean. We assume its Triamterene/hctz with 30 mgs of triamterene and the second number is supposed to be the strength of hydrochlorothiazide hence the 30 slash something... but we the strength of 30/5 does not exist). So we have to call this doctor and find out what's wrong. Usually if we call some of the older MDs who have been practicing for awhile they find our call extremely annoying. One of the doctors here is very inflammatory... he treats medication issues as if our bosses call just to see if they can get a rise out of him. But the deal with this guy is that his rudeness transcends his dealings with pharmacies in the area; he is notorious in our local rural hospital for being rude to the nursing staff. I've done a ton of shadowing in family practice with a couple of doctors and it is a common theme wherever I go that the older doctors hold a sense of superiority over the other members of the health care team, be it pharmacists or nurses. Their superiority complex (although that sounds extreme) is certainly not expressed in an overt way many times, as I know the majority of the older doctors in town are well-respected and well-liked. Hell one of them is even my own personal physician and I wouldn't change doctors if someone paid me.
The fact that the older doctors hold these attitudes is, at least I assume, a reflection of the old system of medicine (in the days before there were nurse practitioners, before pharmacy students made rounds with medical students and came into frequent contact with them in residency). These older practitioners feel they are more educated than the others and therefore more qualified to make judgments. Anytime their judgments are called into question, they react negatively, because they were inculcated into medicine during a time in which they did not understand the extent to which pharmacists were trained. Through circles of informal socialization, they may have come to view pharmacists as nosy and unqualified annoyances. In the present day, however, there is a lot of evidence that recent graduates of medical school hold much more respect for pharmacists... this can be seen in my job where many of the physicians 35 and younger frequently call my bosses for suggestions and are much more receptive to the suggestions my bosses make without being asked to comment (i.e. "This isn't covered by the patients insurance but drug X is much cheaper and is on formulary and it works just as well")..
The nursing thing is roughly similar to how pharmacists deal with store managers in larger chains. The pharmacists desire a great deal of autonomy in their profession. Indeed they have gone through at least six years of education (nowadays its more) and they don't want to be told what to do by a high school grad. who worked his way up the Walgreens/CVS/etc. ladder by having a good "customer is always right" attitude. But the formal structure indicates that store managers are to be in charge of all personnel within the store, including all members of the pharmacy staff. Now obviously there are laws that check a lot of the power store managers have over pharmacists (i.e. a store manager could never tell a pharmacist to fill a script that the pharmacist judged to be harmful to the patient). Additionally, members of store management such as loss prevention personnel wrongfully believe they can demand the keys to the C-II cabinet to make counts (checking for theft by pharmacy personnel) .. but federal law stipulates that pharmacists are the only ones allowed to access the CII cabinet and the pharmacy is not to be entered unless a pharmacist is present)... but still, even in other stuff the pharmacy-store manager relationship is one wrought with hostility and misconception even though it is mostly below the surface. The store managers feel that their power over the pharmacy is one they deserve by virtue of their position; the pharmacists feel the store management is unqualified to make any sort of pharmacy judgement - even generalizing this to issues not related to drugs or patient safety such as the management of cash registers or bad customer service practices...
At any rate, this may be the same situation with the doctor-nurse relationship to a degree - the doctors have more education and are more qualified to make decisions about the direction of treatment - but there are several sociological studies out there that suggest two key things to employment satisfaction: 1. a feeling of impact (making a meaningful difference by virtue of how you carry out your job) and 2. a sense of autonomy.
I would suggest that nurses (necessarily so) lack a complete sense of autonomy in the health care system because, for the safety of the patient, a qualified physician must be supervising care. The physicians want to maintain their autonomy - and attempts, real or perceived, to circumvent this will be met with hostility. The nurses know that they don't exercise decision-making authority but they still are satisfied with their jobs when they feel that even though they aren't at the top of the chain of command, they still make a difference in the care of the patient. They don't want to be treated like robots; simply doing whatever the doctor tells them - in effect, being replaceable by anyone off the street. Yes they are willing to follow the physicians orders but they do want to be treated as though they too are professionals who can input meaningful comments or actions that will be accepted by the doctor and lead them to a more satisfying feeling of impact. Sometimes, though, the nurse will try to satisfy this by recommending or offer alternative solutions or even advice to the doctor and the doctor may come to perceive this as an attack on his autonomy (they may perceive the nurse to be inappropriately questioning his/her decision making)... so thus misunderstandings are what cause much of the conflicts between members of the health-care team.
This is where I think much of the conflict comes from...
