Basically, which this is to begin with, Dr. Klotz confines himself to definition, shorter explanations, some procedures and occasional statistics in this favorable bill of health on medicine today. Thus the layman will have some way of distinguishing between doctors and physicians and various specialists, with their subdivisions, in making the right choice; also between individual vs. group practice. He outlines the responsibilities of physicians; presents the A.M.A. positively; discusses hospitals (again choice of, use of, costs and why); insurance plans and some of their difficulties; nursing, the laboratory, dentistry, mental health, down through some of the more marginal categories. On the whole he is cautious (he could be more forthright in, say, recommending use of ophthalmologist rather than an optometrist) but this is a conservative checkup on the profession for the uninformed.
