Health informatics (also called healthcare informatics, medical informatics, nursing informatics, clinical informatics, or biomedical informatics) is informatics in health care. It is a multidisciplinary field that uses health information technology (HIT) to improve health care via any combination of higher quality, higher efficiency and new opportunities. The disciplines involved include information science, computer science, social science, behavioral science, management science, and others. The National Library of Medicine defines health informatics as “the interdisciplinary study of the design, development, adoption and application of IT-based innovations in healthcare services delivery, management and planning.” It deals with the resources, devices, and methods required to optimize the acquisition, storage, retrieval, and use of information in health and biomedicine. It is applied to the areas of nursing, clinical care, dentistry, pharmacy, public health, occupational therapy, physical therapy and (bio)medical research, and alternative medicine, all of which are designed to improve the overall of effectiveness of patient care delivery by ensuring that the data generated is of a high quality.

In the present book, twelve typical literatures about biomedical Informatics published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on medical science concerning biomedical informatics. We hope this book can demonstrate advances in biomedical informatics as well as give references to the researchers, students and other related people.
