Unnecessary tests contribute to healthcare burdenPosted: July 15, 2013
There are times when a doctor knows he’s doing the wrong thing and does it anyway. I’ve done it quite often. This happens when I order laboratory tests for no good medical reason. I am ordering them just to help my patient get their operation or procedure.
A 68 year old man comes to see me for cataract surgery. He has some diabetes which is well controlled with oral medications, and some mild hypertension.
The ophthalmologist’s office sends a piece of paper with him. He needs an EKG, a metabolic panel, and anticoagulation studies. None of this, of course, has anything to do with his cataract surgery. Indeed, if you look up the recommendations of the ophthalmologists regarding cataract removal, they say no labs are needed in a comparatively healthy man.
I grumble, grind my teeth, and then…I order the labs. If I am feeling particularly frustrated, I explain to the patient that I am ordering these labs just to make sure the procedure happens as scheduled, but I don’t think they are medically indicated. I am not sure the patient ever understands what I am talking about when I give this little speech.
What is wrong with these labs, anyway? First, of course, it’s the principle of sticking a needle in someone’s arm and taking blood for a test which is not of any use. Second is that labs can lead to harm. A false positive can lead to more testing, labeling, anxiety, and significant morbidity from the vicious cycle of diagnosis-treatment-side effect which we are so often mired in.
If that’s the case, how do we change matters? That’s something I don’t think anyone’s figured out yet. I played a small part, through the National Physician Alliance’s Top 5 lists of most commonly done useless and potentially harmful procedures, in the birth of the Choosing Wisely movement, which has since been publicized by the American College of Physicians and the American Board of Internal Medicine Foundation. But limiting preoperative labs is actually not part of this campaign.
This is such a difficult problem to fix because it involves everyone at once. The specialist requests these tests because that’s the way it’s always been done, perhaps just because they still have 750 copies of the pre-op handout. The receptionist in their office wouldn’t understand if an internist raised a fuss; she might likely think that the doctor was just being a jerk, and then the patient (caught in the middle, as usual) would not get their cataract removed as scheduled. Then everyone would be annoyed at the doctor who got in the way.
As usual, it’s easier to go along and get along, even at the price of unnecessarily disruptive and unneeded procedures. Can we all sit down together and try to wean ourselves of the needless INRs?
