This little book introduces concepts that are important for all practicing physicians to understand. To quote from the text:
Medical decision making is a process followed by every physician for every patient. You can do it haphazardly or you can do it rationally. You can rely on experience, intuition, and subjective judgment alone, or you can enhance those important attributes with consistent, rational, and powerful tools for identifying and clarifying the decisions most likely to lead to the desired results.
