Special Populations: Disaster Care Considerations in Chronically Ill, Pregnant, and Morbidly Obese Patients.

Special populations, which include the morbidly obese and patients with chronic, complex medical conditions that require long-term health care services and infrastructure, are at increased risk for morbidity and mortality when these services are disrupted during a disaster. Past experiences have identified significant challenges in restoring necessary care services to these patients following major environmental events. This article describes the impact of disasters on special populations, provides a framework for future disaster preparation and planning, and identifies areas in need of further research. Gravid patients, who are often overlooked in disaster planning and preparation, are also discussed.
