Data is not always the path to identifying good medicine. Quality and cost measures should not be perceived as “scores,” because the health care process is neither simplistic nor deterministic; it involves as much art and perception as science—and never is this more the case than in the first step of that process, making a diagnosis.
I share the following story to illustrate this lesson: we should stop behaving as if good quality can be delineated by data alone. Instead, we should be using that data to ask questions. We need to know more about exactly what we are measuring, how we can capture both the physician and patient inputs to care decisions, and how and why there are variations among different physicians.
A Tale of Two Doctors
“As soon as I start swimming, my chest feels heavy and I have trouble breathing. It is a dull pain. It is scary. I swim about a lap of the pool, and, thankfully, the pain goes away. This is happening every time I go to work out in the pool”.
Her primary physician listened intently. With more than 40 years of experience, the physician, a stalwart in the medical community, loved by all, who scored high on the “physician compare” web site listing, stopped the interview after the description and announced, with concern, that she needed to have a cardiac stress test. The stress test would require walking on a “treadmill” to monitor her heart and would include, additionally, an echocardiogram test to see if her heart was being compromised from a lack of blood flow.
“But, I have had three echocardiogram tests in the last year as part of my treatment for breast cancer and each was normal. Why would I need another”?
“Well, I understand your concern about more tests, but the echocardiograms were done without having your heart stressed by exercise. The echo tests may be normal under those circumstances, but be abnormal when you are on the treadmill. You still need the test, unfortunately. I want to order the test today and you should get it done in the next week”.
