Looked over my posts and I haven't mentioned PAs at all, but regardless, I know what you mean. I think the PA model is excellent and support it wholeheartedly. If I had to choose, I would quickly pick multiple PAs in an MD team to help fill the healthcare gap vs. filling it in with NPs/DNPs.
To the independent practice of D/NPs, I agree that they would obviously be limited in diagnosis making capacity. It's why I said I would be wary of having them see every patient that comes in from the ED. Now for a patient who's been diagnosed with HTN, is started on medications, etc and needs routine follow-up, I think they that would be a good role for follow-up.
To Zenman, I fully trust that you are excellent in what you do. However, your individual experience is not representative of the whole population. Moreover, outpatient psychiatry tends to be one of the more algorithmic fields, where you have a DSM checklist to guide you and the opportunities for acute travesty are minimal and in such cases (suicide or homicide being the most imminent dangers in psychiatry, and antipsychotic med adverse effects I am sure you are well aware of and can manage) the guidelines are more straightforward. If you feel comfortable practicing independently in a consult-liason service managing neuroleptic malignant syndrome and other acute problems, then I would be very impressed. It is very likely that you are as good as anyone else at dx'ing and treating psychiatric conditions; education is what you put into it, afterall. Now, should you also be as comfortable treating a pneumothorax? Probably not. But I would also argue that any psychiatrist out of medical school likely has forgotten to do so as well! What I'm trying to say is, that because of your years of specialty training I trust you are performing superiorly and, like your boss, I wouldn't mind patients calling you doc. Afterall, in the truest sense of the word, doctor means teacher, and this is what you are to them. The issue is with newly minted D/NPs who have a sense of entitlement for the title, but do not posses any of the relevant experience or training; whereas their trust in you is well-founded given your experience, the title may inspire confidence in patients for fresh-faced D/NPs that deters them from a healthy dose of skepticism that should be encouraged in all patients in order for them to receive the best care.
If a patient wants to go ahead and call someone doctor, by all means they should go for it and no one should stop them. However, I would say that this should be their choice. I think that rule is good for MDs, DNPs, PhDs. Hours of course work should not beget the respect of a patient in clinic, but you should strive to earn it continually. I get incredibly frustrated when I hear people correcting patients to call them 'doctor' from all levels.
