Despite our best efforts, physicians do sometimes get it wrong. In fact, a 2013 study of more than 350,000 malpractice claims found that missed, incorrect, and delayed diagnoses were the most dangerous mistakes doctors made, and they're estimated to result in permanent injury or death for up to 160,000 Americans annually. But you can protect yourself: The best way to dodge medical mishaps, from medication errors to unnecessary surgeries, is to help your doctor help you. Start by asking these questions at your next appointment.
Do you need to see the tests my other doctor ran last year?
I always urge people to learn their full family medical history, because it helps doctors detect conditions that can be hereditary, like heart disease and cancer. But you don't want to be so busy tracking Aunt Mona's medications that you forget to thoroughly chart your own health history. A study in the Archives of Internal Medicine found that 10 percent of diagnostic errors occur because doctors lack the patient's complete medical history.
Be prepared: Call any doctor you've seen in the past five years (if you can go back further, even better) and ask for copies of your records. These files contain much more than just your vitals; they include consent forms, physicians' orders, test results, pathology reports, and immunization records. The information could help specialists avoid repeat testing (and spare you unnecessary radiation from scans) or connect the dots to a diagnosis another doctor might have missed. You may have to fill out some paperwork or even pay a small fee (for postage or copies of X-rays or MRI films), but don't let that deter you. You have the right to access your health information.
