When APRNs try to lobby their state congress for independent practice, they often cite studies showing that outcomes are similar when comparing APRNs such as NPs versus MDs. Unfortunately, those studies suffer from a massive confounder since the APRNs always have an MD supervisory backup since it's illegal not to before they lobby for that ability. The studies though make it seem like they are just as "safe" as MDs. However, APRNs typically do NOT take the more complicated cases and refer them out to MDs. For basic things, I'm sure many outcomes may be similar.
The philosophy of nursing school is much different than that of medical school and residency. Nursing schools teach similar subjects to medical schools, but are not held to quite the same standard. For example, they don't have to take USMLEs, which if they want to practice independently, they should to demonstrate their clinical knowledge. We look at DOs are equivalent now because they take the same board exams as MDs do, but historically this was not always the case.
Their clinical training also has an emphasis on how to carry out orders - putting in IVs, knowing how to pull drugs and administer them, knowing how to physically take care of patients, skills that physicians often aren't comfortable with. This was historically the division of labor. A medical student and resident training emphasizes how to make the final clinical decision based on physiology, pathology, and pharmacology, especially when you're on call and you are responsible for the outcomes of the patients.
Nursing schools and their clinical training does not give them nearly as much practice in the final clinical decision making and therefore they have much less clinical judgment than an MD has. They often feel like they can though because they're exposed to it often and criticize doctors for making certain decisions, but often don't get to wrangle all the risks and benefits in decisions that MDs make on a daily basis.
And we're not talking about a mere obvious length in training. We're talking about 20 times as many hours. Some NP programs are almost fully online too, with around 2-3 months of clinical work to get an NP degree. (
