Last year customer satisfaction with the veterans' health system, as measured by an annual survey conducted by the National Quality Research Center, exceeded that for private health care for the sixth year in a row. This high level of quality (which is also verified by objective measures of performance) was achieved without big budget increases. In fact, the veterans' system has managed to avoid much of the huge cost surge that has plagued the rest of U.S. medicine.

How does the V.H.A. do it?

The secret of its success is the fact that it's a universal, integrated system. Because it covers all veterans, the system doesn't need to employ legions of administrative staff to check patients' coverage and demand payment from their insurance companies. Because it covers all aspects of medical care, it has been able to take the lead in electronic record-keeping and other innovations that reduce costs, ensure effective treatment and help prevent medical errors.

Moreover, the V.H.A., as Phillip Longman put it in The Washington Monthly, "has nearly a lifetime relationship with its patients." As a result, it "actually has an incentive to invest in prevention and more effective disease management. When it does so, it isn't just saving money for somebody else. It's maximizing its own resources. In short, it can do what the rest of the health care sector can't seem to, which is to pursue quality systematically without threatening its own financial viability."

Oh, and one more thing: the veterans' health system bargains hard with medical suppliers, and pays far less for drugs than most private insurers.

I don't want to idealize the veterans' system. In fact, there's reason to be concerned about its future: will it be given the resources it needs to cope with the flood of wounded and traumatized veterans from Iraq? But the transformation of the V.H.A. is clearly the most encouraging health policy story of the past decade. So why haven't you heard about it?
