Results of rapid needs assessments in rural and urban Iowa following large-scale flooding events in 2008.

Background: On June 8 and 9, 2008, more than 4 inches of rain fell in the Iowa-Cedars River Basin causing widespread flooding along the Cedar River in Benton, Linn, Johnson, and Cedar Counties. As a result of the flooding, there were 18 deaths, 106 injuries, and over 38,000 people displaced from their homes; this made it necessary for the Iowa Department of Health to conduct a rapid needs assessment to quantify the scope and effect of the floods on human health.

Methods: In response, the Iowa Department of Public Health mobilized interview teams to conduct rapid needs assessments using Geographic Information Systems (GIS)-based cluster sampling techniques.

Disaster triage systems for large-scale catastrophic events.

Large-scale catastrophic events typically result in a scarcity of essential medical resources and accordingly necessitate the implementation of triage management policies to minimize preventable morbidity and mortality. Accomplishing this goal requires a reconceptualization of triage as a population-based systemic process that integrates care at all points of interaction between patients and the health care system. This system identifies at minimum 4 orders of contact: first order, the community; second order, prehospital; third order, facility; and fourth order, regional level.

Preventing tragedy: balancing physicians' ethical obligations to patients and the public.

The recent shootings at Virginia Polytechnic Institute and State University (Virginia Tech) suggest that an increased reliance upon the medical community to support public health violence prevention efforts may be warranted. As physicians are called upon to support these efforts, they must effectively balance their obligations to promote public safety with their traditional obligations to promote the best interests of their individual patients. To meet these concurrent ethical obligations, physicians' participation in public health violence prevention should seek to improve public safety without compromising the care of patients or exposing individuals to undue harm.

Ethical obligations of physicians participating in public health quarantine and isolation measures.

In dealing with outbreaks of communicable diseases, the medical profession should work with public health authorities to promote the use of interventions that achieve desired public health outcomes with minimal infringement upon individual liberties. This article endeavors to help physicians manage their dual responsibilities to their patients and to their communities when participating in appropriate quarantine and isolation measures. In implementing such measures, individual physicians should take necessary actions to promote patients' well-being.
