Almost all discussions about Medicare reform ignore one key factor: Medicare utilization is roughly 50% higher than private health-insurance utilization, even after adjusting for age and medical conditions. In other words, given two patients with similar health-care needs—one a Medicare beneficiary over age 65, the other an individual under 65 who has private health insurance—the senior will use nearly 50% more care.
Several factors help cause this substantial disparity. First and foremost is the lack of effective cost sharing. When people are insulated from the cost of a desirable product or service, they use more. Thus people who have comprehensive health coverage tend to use more care, and more expensive care—with no noticeable improvement in health outcomes—than those who have basic coverage or high deductibles.
Its amazing that we still have serious public debates about which way demand curves slope.
