The text is well organized, well referenced, well edited, and practical in its content. Central to the practice of acute care psychiatry—and all psychiatry, for that matter—is an accurate assessment of the patient. The first section of this text addresses that task, with a format following Sederer's "four questions.” These questions address the patient's descriptive and differential diagnosis, ego defenses and character style, current stresses and vulnerabilities prompting the symptom picture, and focal problem or problems to be addressed to restore safety or equilibrium. Subsequent relevant chapters provide a thorough review of risk assessment for suicide, of risk assessment for violent behavior, and of psychiatric triage, crisis intervention, and disposition.
