Unintended Consequences

The drug shortage, especially for chemotherapy, has a strange but predictable source, namely unintended consequences. As NEJM reports:

Before 2003, Medicare reimbursed 95% of the average wholesale price — an unregulated price set by manufacturers — whereas oncologists paid 66 to 88% of that price and thus received $1.6 billion annually in overpayments. To blunt unsustainable cost increases, the Medicare Modernization Act mandated that the Centers for Medicare and Medicaid Services (CMS) set reimbursement at the average sales price plus a 6% markup to cover practice costs. This policy has reduced not only drug payments but also demand for generics. In some cases, the reimbursement is less than the cost of administration. For instance, the price of a vial of carboplatin has fallen from $125 to $3.50, making the 6% payment trivial. So some oncologists switched to higher-margin brand-name drugs. Why use paclitaxel (and receive 6% of $312) when you can use Abraxane (for 6% of $5,824)?

This is abut a small real example of what a failure to think through the process results in. As one of the left wing politicians said when trying to get the recent health care bill passed, she said, "You have to pass it to see what it says." Pass it they did, and if one thinks the current shortage is anything just wait.
