Responding to the request below for a specific example. Hand washing, you wash your hands when medically appropriate to prevent facility acquired infections. If you don't you are progressively warned ultimately leading to termination and/or loss of license. If instituted nationally this alone would save at least 5,000 lives a year. Good luck getting it instituted at most facilities.
A different example, diesel fuel and generator maintenance is a meaningful part of medical facility physical plant. A shocking number of facilities place procurement responsibility and oversight of this in the hands of a doctor who also has medical responsibilities. The results are as financially and operationally disasterous as you would expect. Data centers have similar requirements. Who do you think pays more and operates better?
Formularies are a sort of default medication lookup table. Most organizations have one that was created decades ago by people who aren't with the organization anymore. Review and revise them with someone who understands both the medical/pharmacological aspects of the drugs involved as well as their costs. Win for doctors, win for patients, win for insurers, almost no one does this. They have some clueless administrator carry forward last years formulary with minor changes or alternatively have a medical professional with absolutely no idea what costs are involved do it.
