Do you think doctors often order tests patients don't need? Why?
I had been given several different anti-depressants for chronic back pain which caused huge weight gain. At the same time, I was tired all the time. Work and come home and lay around and sleep.
I have a new doctor who ran routine labs on me (at my suggestion)---my other doctor never ran labs, always prescribed and always did x-rays though---and discovered that I have hypothyroidism and very low magnesium. A few weeks on naturthroid and I feel like a new woman. I'm starting to lose weight and have increased energy. Why couldn't my other doctors figure that out? Just start with a routine lab!

However, they can go overboard thinking that if they don't to test 'h,' 'i,' and 'j,' that they'll not have met the burden of proof needed by insurance companies to justify a diagnosis. WHO pays for these excesses? WE do. We need to change this system, because doc too often order excessive tests to avoid lawsuits. Defensive medicine!
The best remedy to "defensive" medicine is "preventative"medicine. Unfortunately, that's something that would require effort on the patient's part...
And, who wants that?
Sometimes it is not updating practice standards- hard not to do what you were taught to do in medical school- although this is not a good excuse in my book.
Sometimes it is an effort to be thorough- I am not a doctor but I can only guess the fear that you may miss something important, and in the decision point it is easier to er on the side of caution. In my own experience as a nurse I usually will do more testing if I think it is all indicated (more frequent bp checks, glucose checks, exams etc) on my shift. It is not an issue for me though because it does not raise expenses- although it may greatly annoy the patient.
I cannnot count though the times my hunch was right and I caught an issue before it turned into a major disaster.I agree with brunosbud though about the preventative medicine issue- unfortuately it does not pay to do much preventative medicine so it gets sidelined often.
It's a shame.
MarySings above has the reason why.
Many times I have said to myself. "This test isn't needed for me. Its needed for the doctor as a CYA for himself. I'm paying money for an unnecessary test to cover the doctor's hind end."
But there can be another motivation. Medicine is private business in the States. Its perfectly normal to up sell in any business. Doesn't matter what product or service is being offered. Could be a used car, a hamburger, or medical tests.
The big difference between selling a hamburger and medical tests-- when buying a burger they ASK YOU if you would like fries with your order. With medical tests your paying for more services, like it or not.
Example: My doctor and I both agreed that at age 35, with periods so heavy I became dangerously anemic, the ideal solution would be a hysterectomy. The insurance company insisted we try a D&C, then birth control pills, then surgery for endometriosis, then shots..... After being jerked around for 18 months, 7 drugs and two surgeries, my doctor got someone at the insurance company on the line and asked directly what it would take to get me a hysterectomy immediately. The answer? Stage 4 cancer or an abdominal injury that made a hysterectomy the only viable method of stopping the bleeding. The insurance company thought it was being more than reasonable when it said it would pay for monthly transfusions rather than surgery to actually correct the problem. I'm 45 now and still swear vehemently every time my PAP smear is normal. If that doesn't seem wrong to you, you need serious help.
