Too many medical tests can be harmful

Recent headlines offered a fresh example of how the health care system subjects people to too many medical tests – this time research showing millions of older women don`t need their bones checked for osteoporosis nearly so often.

Chances are you`ve heard that many expert groups say cancer screening is overused, too, from mammograms given too early or too often to prostate cancer tests that may not save lives. It`s not just cancer. Now some of the nuts-and-bolts tests given during checkups or hospital visits are getting a second look, too – things like routine EKGs to check heart health, or chest X-rays before elective surgery. Next under the microscope may be women`s dreaded yearly pelvic exams.

The worry: If given too often, these tests can waste time and money, and sometimes even do harm if false alarms spur unneeded follow-up care.

It begs the question: Just what should be part of my doctor`s visit?

If you`re 65 or older, Medicare offers a list of screenings to print out and discuss during the new annual wellness visit, a benefit that began last year. As of November, more than 1.9 million seniors had taken advantage of the free checkup.

For younger adults, figuring out what`s necessary and what`s overkill is tougher. Whatever your age, some major campaigns are under way to help. They`re compiling lists of tests that your doctor might be ordering more out of habit, or fear of lawsuits, than based on scientific evidence that they are really needed.

`Too often, we order tests without stopping to think about how (if at all) the result will help the patient,` wrote Dr. Christine Laine. She`s editor of Annals of Internal Medicine, which this month published a list of 37 scenarios where testing is overused.

Not even physicians are immune when it comes to their own health care. Dr. Steven Weinberger of the American College of Physicians had minor elective surgery for torn knee cartilage about a year ago. The hospital required a pre-operative chest X-ray, an EKG to check his heart, and a full blood work-up – tests he says aren`t recommended for an otherwise healthy person at low risk of complications.
