Some have interpreted this as further fracturing of patient care, splitting a patient’s healthcare experiences between an out- patient and inpatient world. Others, myself included, argue that this new endeavor allows for comprehensive, patient- centered hospital care, with a team of physicians and other providers who have special expertise in hospital- based medicine. This book is not meant to be an all- inclusive text of the medical issues encountered in the hospital. I’m sure that any text aimed at inpatient adult medicine would be defi cient in some aspect of the depth and breadth of care provided by today’s hospitalists. In addition, this is not a collection of algorithms to direct the care of individual problems. In my career as a hospital- ist, I have found that not many inpatient decisions can be guided simply by an algorithm. There are too many competing interests of risks, benefi ts, patient and family wishes, local practice, and knowledge and comfort level of the physician. In The Little Black Book of Hospital Medicine, I have tried to provide a framework for managing the major problems we, as hospitalists, encounter every day. This includes thoughtful review of the issues and also an overview of the important clinical research that guides our decisions. When available, I have tried to summarize the best available evidence supporting a particular test or intervention, so that we may help our patients make an informed decision about their care.
