Dr. Johnson, prominent in media and educational spheres, a minister as well as a physician, has written an enlightened book--a ""guide"" to enable you to ""choose"" better health care and to eliminate much of what is both expensive and worthless. It is gratifying to see him promoting the ""primary care"" or family physician who is now on the way back; it is surprising (and true) to hear him say that most annual check-ups have been over-promoted (only four annual tests are essential--the Pap, breast, blood pressure and glaucoma); his advice on the choice of hospitals (a teaching hospital by all means) and doctors is needed by many who overrely on their friends who say he's the ""best."" He's circumspect in many areas in which he admits justified doubt (psychiatry); he provides an important run-through of emergencies from stroke to cuts. He does not discuss all diseases but he provides a very extensive briefing on heart, lung cancer, GI and infectious diseases, and women's health problems; he appends a dictionary of two- to three-paragraph descriptions of anything from acupuncture to the hyperactive child. Johnson sponsors the best kind of medicine; reasonable, qualifying, responsible, he should enable you to get it.
