Atul Gawande in the New Yorker:

Medicine involves hundreds of thousands of local entities across the country--hospitals, clinics, pharmacies, home-health agencies, drug and device suppliers. They provide complex services for the thousands of diseases, conditions, and injuries that afflict us. They want to provide good care, but they also measure their success by the amount of revenue they take in, and, as each pursues its individual interests, the net result has been disastrous. Our fee-for-service system, doling out separate payments for everything and everyone involved in a patient's care, has all the wrong incentives: it rewards doing more over doing right, it increases paperwork and the duplication of efforts, and it discourages clinicians from working together for the best possible results.
