This book is based on surveys of where leading health professionals would go if they wanted the best medical care. Includes allergy/immunology, dermatology, endocrinology, eye surgery, heart-lung transplants, etc. Possibly the medical industry did not like being graded like this, so this has become a rather hard to find book. Should have continued to come out with updates every few years to keep up with all the new medical centers, etc being built. Then again, a lot of centers have fallen below standards, or rather, the standard keeps being lowered under financial pressures.
