Preventing Care and Cost Savings
The theory goes like this: By practicing preventive medicine, doctors can keep many people from getting sick in the first place. Those who do end up with a chronic illness will be closely tracked so that fewer of them develop complications. These steps will result in less illness, which in turn will require less health care. With the savings, the country can then lower its medical bills or provide health insurance for the 40-odd million people who lack it — or maybe even both. . . .
The would-be reformers have hit on something important here. The current health care system doesn’t pay hospitals, doctors and nurses to keep people healthy; it pays for tests, surgeries and drugs. So Americans often get expensive invasive care of dubious medical benefit while missing out on sensible basic care. Millions of other people go without any care for chronic illnesses like heart disease and diabetes. If Medicare and private insurers paid for more preventive care, Americans would be healthier than they are today and live longer. . . .
No one really knows whether preventive medicine will save money in the long run, let alone free up the billions of dollars a year needed to help pay for universal health insurance. In fact, studies have shown that preventive care — be it cancer screening, smoking cessation or plain old checkups — usually ends up costing money. It makes people healthier, but it’s not free. . . .
This is a tough idea to swallow because better health really does seem as if it should lead to lower medical bills. Indeed, if it were somehow possible to wave a wand and turn people into thin nonsmokers who remembered to take their statins, this country’s health care expenses would fall.
But any effort to promote health has its own costs. Doctors and nurses need to spend time with patients to persuade them to change their behavior. (Ever tried to get someone to stop smoking or drinking?) For a new program to work, it has to reach people who are not being helped by whatever exists now — and who thus will be among the most difficult and expensive patients to treat. The program would also have to treat a whole lot of people who never would have gotten sick. . . .
The actual savings are also not as large as might at first seem. Even if you don’t develop diabetes, your lifetime medical costs won’t drop to zero. You might live longer and better and yet still ultimately run up almost as big a lifetime medical bill, because you’ll eventually have other problems. That would be an undeniably better outcome, but it wouldn’t produce a financial windfall for society.
Mr. Klein notes, in response, "This is all true. To be sure, in a perfect world, I could probably dream up a set of policy initiatives that, if broadly implemented and competently carried out, could reduce health spending off the bat. But the world continually disappoints with its stubborn lack of perfection. Instead, the more achievable goal is to move towards a universal system that's more cost-effective, which is, in fact, very much the same thing as saving money, and towards an integrated system that readies the ground for tougher cost control mechanisms down the road."
