Holistic 100% care doesn’t exist - even for the rich.
The only way to get optimal care is to pay for it with study. Even the richest in the world don’t necessarily get the best care because care is a function of the present life situation of the practitioner - something no one can control 100% of the time.
What is reassuring is that through a little study - you can refine the care provided by most nurses and doctors using your own curiosity at the point of interaction.
Surprisingly the mistakes committed by nurses and doctors on somewhat healthy patients are easily fixed with some sembalance of attention.
Study the first 2 years of med school. It’s not hard but does take time. And then ask the pertinent quesitons during your time with the doctor. Understand the diagnosis and how they came to it - it’s mostly simple and straight forward.
80% of the massive mistakes by doctors and nurses are fixable this way. Thats $800B … 800 billion dollars - with a little study.
