My test-ordering evolution as a rheumatologist

Perhaps one of the biggest ways in which I’ve evolved as a doctor over the 4.5 years I’ve been in private practice is that I am not so shy about ordering tests anymore.

My point is illustrated by the case of a lovely lady I met when I was starting out in practice who complained of being in pain all the time. She was referred to me for a very low titer antinuclear antibody and a barely positive rheumatoid factor. She’d had a very long history of severe depression and anxiety. She clearly connected her symptoms to having stopped her antidepressants. She attributed her dry mouth to her benzodiazepine. I told her that I thought she had fibromyalgia and that, as she herself pointed out, it was probably related to her emotional health. We talked about the lack of any real pharmacologic treatment for the illness. We addressed self-care: that she needed to sleep better, exercise more, and treat her depression.

Three years later she came back to me with hand swelling, hypergammaglobulinemia, renal tubular acidosis, this time with significantly higher ANA and RF titers, and hypocomplementemia. You guessed it; she has Sjögren’s syndrome.

Seeing patients 40 hours a week has been incredibly challenging but also incredibly rewarding. While the large number of cases that I’ve seen has sharpened my clinical eye, it has also broadened my differential diagnoses and improved my knowledge of when it will be helpful to order more tests.

It used to be that I was extremely conservative about ordering tests. This comes from having gone to med school in the Philippines, where each test was paid for by the patient out of pocket and GDP per capita is $2,765 (compared with $53,041 for the United States) and minimum wage is less than 2 dollars a day. Every CBC has to count. If a professor asked you why you were ordering a test, “to establish a baseline” was an unacceptable reason. When I started residency here, I was incredulous that the admitted patients got a CBC and chem-7 daily. This seemed like a huge and unjustifiable waste to me.

Today, I am not so uptight. Of course, I am still extremely thoughtful about ordering tests. I do not order tests without knowing what I am looking for, or how the result will affect management. But I also recognize that there is a non-zero probability that what I suspect is fibromyalgia is something else, something with a different prognosis, better or worse, something that needs to be managed and monitored differently.

After all, “clinical judgment” does not mean relying on the history and physical exam alone. Good clinical judgment requires medical knowledge, informed by experience, supplemented by test results, and complemented by an open, inquisitive mind.
