Cost-awareness anecdote: Cruel Shoes

The following story is from Dr. John Henning Schumann, a primary care doctor at the University of Chicago. He blogs @ http://glasshospital.com

A thirtysomething friend of mine, let's call her Sally, started running last year in an effort to get in better shape.

As often happens in these scenarios, Sally developed some foot pain. So she went to a "foot" doctor (I'm not sure whether she meant a podiatrist or an orthopedic surgeon specializing in feet).

Reasonably enough, the doctor ordered an x-ray of her foot. The official reading showed no fracture, but there was a "questionable" finding on the edge of one of the midfoot bones such that the doctor couldn't rule out some more insidious process. A stress fracture, perhaps? Those can be awful, and take a long time to heal.

So, again in reasonable fashion, the doctor ordered a CT scan of Sally's foot. This is the logical next step if a plain old x-ray is abnormal. Heck, a lot of the time, even when an x-ray is normal, we still order the CT scan looking for something that we can't see on the x-ray.

And though I said this was a reasonable choice, if you really think about it, was it so reasonable?

I mean, did Sally really need a $1000 test to see what was causing her foot pain? If you're Sally, you sure might think so. You want to know what the heck's wrong. You want to know why you're having pain when you run. You want to keep running. After all, as a primary care doctor, I LOVE it when a patient tells me that they're serious about exercise. Aside from not smoking, that's the best thing I can hear from a patient.

But Sally hadn't traumatized her foot. She hadn't dropped a bowling ball on it. She probably had an overuse syndrome. A repetitive stress injury. A running "tweak."

The x-ray showed that, for heaven's sake. We knew there was no broken bone. No smoking gun. [I told you, we hate smoking.]

So a week after sitting for the CT, Sally still didn't know the result of her scan. She called the doctor's office to no avail. She was put off by the staff, even told by a nurse she'd have to come in for an appointment to discuss the results with the doctor.

By this point, she's worried. "Is there something terrible that he's waiting to tell me?" she wondered. "Do I have foot cancer?"

Sally adjusts her schedule, dutifully shows up for the appointment, to hear the doctor tell her that her CT is normal. Did she really have to wait a week and have an office visit to find this out? That is one shoddy patient experience in my book.

Nevertheless, she reasonably asks the foot doctor what she should do about her pain.

Physical therapy? Low impact exercise (use an elliptical trainer, perhaps, or bicycling)?

She doesn't get much of a concrete answer.

She decides to buy some new shoes.

She goes to a local shoe store that caters to runners. Let's call it Fast Feet.

There, they measure her feet. No charge. Lo and behold, her feet have grown a whole size.

Sally was running with shoes that were too small! That was the source of her pain. No CT was needed. In fact, probably even an x-ray was unnecessary. And the $300 orthotics that she' been prescribed.

Now, this story shows how when a patient comes to see a doctor, we often go right to diagnostics. We want to get you an answer, after all. We're not shoe salesmen, for heaven's sake. We don't even have those thingie-dingies that measure feet. [Do foot doctors?]

Next time someone comes in complaining of foot pain, I'm going to ask them when they last had their feet measured.
