On Achieving Access and Equity in Health Care

Abstract

This paper addresses some of the issues related to health care in the United States. In so doing, I give primary emphasis to questions involving access to health care. Even so, I limit the discussion of any particular topic to its most important facets. The principle of selection involves various criteria: insofar as possible, I discuss those issues that are important at a system level (particularly as they impinge on the allocation of resources), that involve economic arrangements influencing behavior and performance, and that can be illuminated by the economist's perspective. I attempt to give primary emphasis to those variables whose influence is far ranging. In so doing, of course, we cannot examine every network of interrelations. Although this simplifies the discussion, we pay a price for incompleteness. There is little choice, however. One of the difficulties with the health field stems from the fact that everything is interrelated: that intervention on one front has “side effects” on other fronts; that intervention designed to accomplish one purpose sometimes fails to do so because other factors that appear unrelated are not changed. To discuss everything is impossible. On the other hand, to say nothing because we cannot discuss everything is irresponsible. Finally, we will have to reach judgments even in spite of the relative weakness of the data available for analysis. We know far less, for example, about the availability of services (particularly if corrected for quality differentials) than we would like to. So, too, with the impact of differences in utilization on levels of health. The current refrain often seems to be, “But we have no output measures.” That, regrettably, is frequently the case. Nevertheless, just as we cannot be silent because of the complexity of intertwined relations, neither can we be silent because of insufficiency of data. We can use experience and judgment to arrive at (tentative) conclusions. Not knowing everything does not mean we know nothing.
