1. Health care is generally not a refusable or elective service.By this, I mean that in most cases, the health care costs are driven by medically necessary procedures. You get pneumonia. Your knees wear out. You find a lump in your breast. You notice blood in your stool. Barring the denial/self-neglect approach that some people take, when you develop a medical problem, you need to spend money to remedy it. While the timing of your knee replacement may be elective, whether to do it or not generally is not, if the alternative is being disabled and non-ambulatory. It is an inelastic demand, like the demand for gas. When gas gets more expensive, you still have to fuel your car, and except for very small variations, the demand for gas does not vary with the price. Similarly, the demand for medically needed care is not going to be terribly price responsive. When your doctor tells you that you need chemotherapy, you don't make the decision to proceed based on the cost, but on the need. And the number of recreational colonoscopies performed is actually very low.
It is true that some medical costs are elective and price sensitive -- preventative care, luxury procedures like Lasik, some office visits. These, however are a tiny fraction of overall health care costs. As in my analogy, some people do drive less when the price of gas goes up -- they take the bus instead -- but this does not reduce demand enough to make a difference in the price of oil.
2. There is an asymmetry of informationThis asymmetry relates to both price and necessity. When your orthopedist tells you that your knee pain is due to a degenerated meniscus and that the best treatment for that is athroscopy, most consumers are going to simply accept the surgeon's advice. Now, as it happens, there is good evidence that arthroscopy of the knee provides no more benefit than placebo, but 99% of patients are not going to be aware of this and are not going to bother to do the research to find it out. Those that do, might find that the surgeon has an explanation why, in your case, he thinks it will be helpful despite the studies showing otherwise for other people. In most cases, the patient must trust the physician to provide accurate information on what is really needed. And if you should ask your surgeon what the cost of the arthroscopy will be, the answer will probably be "I don't know." Price transparency is poor to begin with but there is the very real fact that based on a patient's individual payer status the cost will vary dramatically, and the surgeon probably does not know what the cost will be for your case. Finally, when consumers make health care providers compete against one another to decide by whom and where the care will be given, they tend to be concerned primarily with quality and with cost as, at best, a secondary concern.
All these factors greatly inhibit competition and the development of a free market. To some degree it is possible to mitigate these, through, say, all-payer price setting, and mandatory disclosures and publishing outcomes data, etc. However, the third variable, in my opinion, makes the rest all-but-moot.
3. Purchasing power is concentrated in the hands of a very small number of "consumers"This is the wooden stake through the heart of the idea that consumer behavior can effect cost containment. The functioning of a free market is dependent on the ability of consumers to vary their behavior to force suppliers to compete. However, you and I can be as scrupulous and cost conscious as we like. We are not sick. (Well, I'm not anyway. I hope you're OK.) The driver of cost is the small fraction of people who have serious medical conditions. It's the old 80/20 rule writ large.
I've heard of some doctors performing "recreational colonoscopies" on irritating patients. Tip from the pros: always be nice to your gastroenterologist.
