An often forgotten component of disaster response is care for those with serious mental illness. A full chapter is devoted to this topic and covers it well. In times of disaster, persons with chronic illnesses of all kinds lose access to care, lose their caring community (physicians, nurses, and health care providers), and lose their medications and other treatment interventions. Whether those are antipsychotic medications, antianxiety medications, oxygen, or renal dialysis, the impact of loss of care is an important focus for ensuring health and well-being in disaster-stricken populations. Similarly, the book highlights issues of substance abuse, including data documenting that substance use increases after exposure to trauma and disaster, although the data on the new development of substance abuse after such events are less compelling. Increased substance use is a risk not only to the individual but also in workplaces and on the highway, where vehicular accidents can be a major outcome of psychiatric distress. The management of medical complaints and the role of triage are also discussed.
