The New York Times has a story today on the unintended consequences of a new Medicare payment system. It’s an ominous outcome that was largely predictable. There’s a better alternative for how these payment approaches should operate.
At issue is a new payment scheme that pays renal doctors a lump sum, or “bundled payment,” for taking care of dialysis patients. Under the program, the doctors mostly get one fixed payment regardless of how much time they spend with patients, or how many drugs and procedures they use in caring for these folks.
These “bundled payments” are a key feature of the Obama health plan. That legislation uses various forms of capitation to shift financial risk onto providers in a bid to cut down on the use of costly, and some argue wasteful, medical services.
A new study shows that the use of some important, but also expensive, drugs has gone down sharply as a result of this payment approach.
At issue are drugs used to boost red blood cells. Most dialysis patients end up with anemia as a result of their kidney failure. The diseased kidneys are unable to produce a hormone that stimulates the generation of red blood cells.
So most patients are given drugs like epogen that mimic these hormones and are used to boost the production of new red blood cells. But the drugs are costly, and use has gone down sharply under the new payment system. The new study finds that the number of patients needing blood transfusions as a result has risen sharply.
The problem is with the bundled payment itself. The scheme pits the physician’s reimbursement directly against the cost of his choice of technology used in caring for an individual patient. It’s not a surprise that the use of technology would go down under such an incentive system.
A more optimal approach to bundling payments would have the services and the technology paid separately. If Medicare wants to bundle payments to providers, then the technology that the doctor uses should be paid outside the bundle, ideally in a competitively bid system (like Medicare Part D) to help make sure Medicare is getting a competitive price for what it purchases. But the doctor’s salary, and his use of a particular drug, should not be put at direct odds with one another, unless we want to see more outcomes like this study finds.
Physicians can be reimbursed with a bundled payment that is based on the outcomes they achieve and some overall measure of their efficiency without having their salaries so directly pit against the cost of the treatment choices they make.
This is having consequences for patient care. As the article states: “In each of the first nine months of 2011, the share of dialysis patients covered by Medicare who received blood transfusions increased by 9 to 22 percent over the corresponding months in 2010… There had been virtually no change in transfusion rates between 2009 and 2010. The implications can be foreboding for patients awaiting kidney transplants because transfusions… can change body chemistry and make it more difficult to find a compatible organ. That makes them more likely to be among the 4,500 Americans who die each year while waiting for kidney transplants.”
