Emergency psychiatry is a burgeoning subspecialty throughout hospitals in the United States. This book is divided into five broad chapters that independently review challenges facing the practice of psychiatry today. Far from being a flowchart manual addressing every possible psychiatric emergency, this condensed guide provides insights into hospital dynamics and physician-patient interactions. The first chapter discusses the different ways that psychiatry emergency services may be organized. The emphasis is clearly on the need for psychiatric staff in the our community emergency departments. The authors supply an informative discussion of the models for delivery of services in emergency psychiatry, how they are organized, and even the kind of impact that the modern practice of medicine (read managed care) might have on the delivery of such services. The second chapter usefully overviews current modes of assessment of patients in psychiatric emergency services at the medical, psychiatric, and cognitive levels. Psychiatry, as with all things that evolve, has developed complex relationships with other disciplines and has interfaced with traditionally distinct spheres such as neurology, internal medicine, and nursing. The authors provide a keen analysis of the necessity of patient care based on these multiple perspectives in the emergency setting.
