Protocols are intended to be an organized framework for delivering care.
Written well, they are a floor, ensuring that even the least competent medic in your system delivers the same basic care as your best medic.
Written poorly, they are a ceiling, forcing the best medic in your system to render care on a par with the least competent one.
That is why you should always question poorly written and overly restrictive protocols.
Restrictive protocols are not written to do the patient the most good.
They are written to do the patient the least harm, because the people who wrote them doubt your ability to think, and use your brain to make good decisions in rendering care.
And as long as you continue to follow those protocols blindly and without questioning their wisdom, those people are right.
