his article from the Archives of Internal Medicine reviews the top five most wasteful procedures in primary care. The first was the ordering of diagnostic imaging such as x-rays, MRI's, and CT's. The second was ordering bone density testing in woman under 65 and men under 70 with no risk factors for osteoporosis.
We now know that diagnostic imaging has a high rate of false positives meaning it can show many abnormalities that have nothing to do with a patients symptoms. This leads to much unnecessary further testing and treatments, some of them with dangerous side effects.
Current guidelines do not recommend bone density testing on woman under 65 and men under 70 with no risk factors for osteoporosis for the same reasons as diagnostic imaging.
