When people die of disease, they are said to have died from natural causes. When they recover, the doctor gets the credit of curing them.
-- George Bernard Shaw.
This may be an apocryphal tale, but a city in ancient China is purported to have had a public health-care system that was the reverse of ours. Physicians were paid a monthly fee for each of their patients as long as the patients remained in good health. When a patient became ill, the fee was suspended.
In that genuine health-care system, the doctor's main incentive was to keep patients well. So the emphasis was on scheduling frequent visits and tests; monitoring nutrition, exercise and other essential factors; and promoting the healthiest possible lifestyle.
