Dr. Pheo's musings on health care cost

I usually do not pay much attention to political arguments. In these days, however, I cannot go a single day without hearing discussions on health care or health insurance reform. A lot of discussions, I feel, are not on the really important issues. Today, I'd like to share my thoughts on one of the key issues in health insurance reform: health care cost.

The one thing everyone seems to agree upon is that the health care cost is too high for our society to afford and "we" spend way too much money on health care in America but only to achieve the same levels of health that other developed countries achieve with much less cost. But who are "we"? Am I one of the "we"? Are the readers of this blog some of the "we"? Who are responsible for the high cost in health care? How do we cut down the cost?

I, as a physician, may contribute to the high cost. For example, although I know that the MIBG scan probably does not add much to the localization of pheo if CT or MRI already finds a clear adrenal tumor in a middle-aged patient with high markers, I order the MIBG scan anyway for this patient because I worry about the small possibility that there may be a second pheo somewhere that I may miss otherwise. Although the literature and my own research show that ordering multiple tests for pheo is not necessary, I sometimes do order 2 markers because there is a small chance that there may be a lab error.

As a patient, you may also contribute to the high cost. Yearly follow-up of pheo markers is sufficient after pheo resection; some patients, though, insist on testing every 3 months because they worry about the small chance that they may have a fast-growing pheo. Some patients demand to have an MRI even after CT shows clear results because MRI does have a small advantage over CT in describing the pheo.

All medically justified costs are not waste. But who determines if a test or a treatment is justified? In reality and in theory, the physicians are the ones who eventually determine if a cost is justified. The insurance clerk who declined the coverage of your MRI just acted on the recommendations made by physicians hired by the insurance company. Although physicians have the intellectual capacity to perform this function, the society as a whole has to decide on a few key issues to make physicians exercise their best judgment on cost justification.

1. Do we trust physicians to do this job at the first place? If we don't, who else do we trust?

2. If we trust physicians, how do we make sure that physicians always exercise their best judgment without playing favoritism?

3. What is the maximal acceptable risk? If there is a 1/million chance a pheo may be missed, most reasonable people don't worry about it. What if the chance is 1/1,000, or 1/100, or 1/10?

4. How much do we want to pay for "peace of mind" and how much physical discomfort is intolerable?

5. Who is responsible for the risk? If I do not order an MIBG on a patient who I feel rather sure only has a solitary pheo but it turns out that the patient does have metastasis, whose fault is it? Am I free of blame because I exercised my best judgment?

6. What is the appropriate mechanism to reward physicians so that physicians are motivated both to avoid unnecessary tests and treatments and to use all necessary tests and treatments?

7. Do the answers to the above questions depend on whether a patient pays everything by her/himself, has private insurance, has public insurance, or has no insurance at all?

Our society has to be reasonable and responsible to achieve an efficient, equitable, and satisfying health care system.
