“The article examined colonoscopy, something which many politicians believe in so fervently as preventive care that they included in ObamaCare a provision that waived the Medicare co-pay for the procedure. That will likely result in an increased use of colonoscopy. The article in the NEJM is particularly useful in shedding some light on whether that policy change will be worth it from a dollars-and-cents perspective. The article examined 2,602 patients who had advanced adenomas (large polyps, usually close to 10 millimeters in size) removed via colonoscopy. In the end, the authors estimated that it saved about 13 people from dying of colon cancer.”
