Also, for seasoned professionals you have to factor in malpractice and insurance coverage as contributing to the inertia.
This doesn't mean that the doctors bury their heads in the sand, but it is a part of the reason providers are resistant to adopting these tools. Relying on their own knowledge and intuition may not be better but it won't hurt them as evidence in a hypothetical malpractice suit. The decision support tool has to be sufficiently better to outweigh this.
I hold no opinion on the validity of this line of thinking, but I can say that it is part of the calculus, at least for some.
Stupid af.
