into view. Will these beginnings of legislative prescription of the practice of medicine be extended into other areas? How shall we know where to stop? Is it wise to legislate the practice of medicine when there are so many biological unknowns which can scarcely be identified let alone committed to paper. Can a legal code replace the exquisitely difficult judgments a physician must make in prescribing for a biologically unique patient? Medical practices sanctioned by law are much more difficult to change than those applied through individual judgment. Laws remain on the books, rigidly fixed, while the state of the art in medicine continues to advance and to change. Yesterday's beliefs become tomorrow's corections.

Before moving, finally, into some concrete recommendations, it should be noted that the PKU laws have provided for the substitution of clinical judgment by a single chemical determination which may or may not have a direct bearing on the disease.

What do I propose?

1. As to mechanisms of advice:

Any one solution, such as some independent ombudsman or office of review in the executive or legislative branches, would be insufficient. Rather, we need a return to old-fashioned scientific pluralism. We need open, constructive conflict of ideas from which truth may emerge. We should not discourage advocacy, dissidence, and special pleading. One approach is to dilute the concentration of advisory Sources. The same people or program sources should not at once guide legislative and executive branches, from within and without, while also dominating voluntary and professional society channels. Let us round out our pluralisms and at least occasionally have some spirited debates over both ends and means, right out in the open.

2. As to program choice and priorities:

The making of choice becomes more difficult as more is learned about situations and problems. On the whole, reliance must be placed on the professional judgments of the experts and the administrators. Legislators must also play a part in choice, for they thereby bring in the popular view-provided it is really that-as opposed to the dominance of professionalism. Yet choice must be subject to criteriabased review, taking into account total needs and total resources. Thus, if PKU programs are still investigational, should we not limit their scope while resources are deployed to improvements in more prevalent areas of mental retardation?

3. As to applications of knowledge:

Before particular disease targets are selected for widespread preventive or therapeutic application, there must first be a base of adequate knowledge derived through fundamental and controlled clinical research. Consistent with advances in clinical experience protracted pilot tests should be conducted in one or more States under controlled, scientifically modeled conditions, in order to derive adequate experience. Progressively, as wider field trials are conducted under varying conditions, independent medical judges without personal cause should evaluate progress. Then, assuming that the program demonstrates its worthiness, it should be expanded at a rate consistent with the development of adequate clinical and laboratory facilities and professional

manpower.

The public should be fully informed as to whether a program is investigational or service-ready. Evaluations against criteria of benefit should be continuous.

The need for developing informational bases as prerequisites for action is just as important in all other areas of public medicine, whether in the regulation of drugs or in the extension of medical services to the public.

4. As to legislative prescription of medical practice:

Legislative enactments of medical practice should be limited to assuring good practice, to protecting the public against hidden or unseen external hazards, and to protecting the rights of patients, especially the incompetent. Laws cannot specify action, when individuals are biochemically and biosocially unique and when the knowledge of medicine undergoes constant change. Laws cannot substitute for the professional judgments of physicians.

Senator HARRIS. Dr. Cooper, I want to say how grateful we are for your presence here and for this very interesting presentation. We had in our conference "Research in the Service of Man," in Oklahoma City, a case study presentation by Dr. Shannon. It had to do with the Salk and Sabin vaccines in the polio situation, and he informed us about how we might go about developing a vaccine, perhaps, in a better way, or at least to indicate the exigencies involved in such development and to learn from our past mistakes and successes. The PKU case you have presented will be very helpful to us, and it is personally very impressive to me although I have no doubt that others may want to appear and dispute your case.

I am not sure how the subcommittee may make recommendations in the implementation of the proposals which you make, but I think a part of our job is to shed light on the general problems, and also to stimulate dialogue between those involved in the social sciences, and in politics and public policy on the one hand, and those involved in biomedicine on the other.

I think sometimes we are mutually suspicious of each other. But we are going to have to become less suspicious if we are going to do a better job than the one we are presently doing. So I think what you have had to say will be very helpful to us, and will be a very important part of the record of these hearings.

I haven't any questions because I think you have made your points very, very well. Do you have anything further you would like to add? Dr. COOPER. Well, your staff talked to me and asked if I might be prepared to elaborate a bit more specifically on some of the thoughts I have had.

I deliberately titled the presentation, "Creative Pluralism, Medical Ombudsman," "because I think it is only through the pluralistic approach that we are more likely to slow down precipitant advances, and bring out the truth.

The problem is, how do the institutionalized mechanisms-the Congress, the executive, the NIH within the executive, because there are different levels of the executive-get independent advice?

If we look at the Congress, it has advice available to it through various committee mechanisms, but the kinds of advice which are generated thereby depend largely on the ability of the committees to bring in people from the outside. I don't think that Congress has any independent mechanism of case building, of looking into situations and using them as case studies for the edification of the Congress, or to develop the issues in depth fundamentally, and this is one area which I would recommend to your committee for exploration.

Within the complex of the NIH, we have advisory councils, and we have study sections which pass upon grants. The advisory councils are supposed to operate at a much higher level and advise the individual institutes, and now the separate National Institute of Mental Health.

I would think that this committee should examine into the laws setting up the advisory councils, to consider whether any changes should be made so that those advisory councils take on less of the character of advocacy and more of the character of visiting boards of review, with perhaps even independently designed agenda, in order to pass upon the program content of the respective institutes, and to provide guidance, and to contribute to constructive dialogue.

There is no advisory council for the NIH as a whole, although in his own wisdom, commendably, Dr. Shannon set up an independent advisory group. I would recommend that your committee examine that and consider whether it might not be set up autonomously, under law, as a body which would advise and consult with the Director of NIH, and not be subject to his call.

So long as Dr. Shannon is in office, I have the utmost confidence he would make the maximum use of it, but we are dealing now with personalities. We should be dealing rather with institutions and longterm arrangements, and we would want to avoid the degeneration of wholesomely conceived mechanisms.

The President and his top establishment need their own mechanisms of independent review. Perhaps the Surgeon General needs it, too. I would have these independent autonomous mechanisms at different levels throughout the executive branch, so that you get varying degrees of integration of views.

But somehow I would also build into the law criteria of membership which would provide for healthy rotation in office, and in some areas, or at least in one or two places of advice for the participation of a really broad spectrum of viewpoint.

We are in a systems era. There is no getting away from that. This is the systems society, as I like to call it. And I think we need people who understand systems technology and institutional mechanisms. For this reason, we ought to have perhaps a cultural anthropologist or a social psychologist or an institutional sociologist, and there are people who have studied in these areas.

We ought to have a political scientist or two brought in independently. We should have people who are expert in the substance of science and people who understand the processes of change, who would say, "Well, you can't move so fast. You can't run that cart ahead of the horse."

These things we need in those mechanisms.

But I think we also need outside mechanisms autonomously created. I wish I could think that we could have it, say through the National Academy of Science. It has its role and it performs commendably well, but it is the peak of establishmentarianism, and I say this in the best sense of the word. I do not know whether you could get independent dialogue under all circumstances through that type of mechanism.

Perhaps affiliated with it, or independent of it, there should be set up, and perhaps the Congress might provide for setting up, a mechanism where people have such insulation from establishmentarianism that they can look independently at things. Yet, on the other hand, we need responsibility.

We cannot be bowling over all of our establishments. We cannot have too many people, even such as I, who are raising dissident voices and who prevail, because we dissidents can also be wrong, and this is why I suggest creative pluralism.
