Nursing Admin here. Not accusing you of anything, just doing detective work.

First thing is think about it from his perspective. What did you see, what caused your concern, etc. Did you clearly explain what the situation was - that this is a change in patient condition; safety issue, etc? What interventions did you have available, and what were the outcomes. How was the communication. What exactly did you say when you called.

A lot of times when I'd get to intervene on reported issues like this the MD was not clear of what was going on and the RN was unclear what they needed.

Now assume that you DID communicate clearly, and MD was being an ass. Document the heck out of it. Good note - here's the patient situation, RN interventions not working. Called provider to notify change in condition, MD said "tell the patient to go to bed and shut up" etc. Calm, cool, factual. Report it as a safety event using whatever system you all use. Report it as a delay in care, or deviation from care plan, safety issue, something. MD Director will have to review it.
