ReviewSurviving collapsed structure entrapment after earthquakes: a "time-to-rescue" analysis.
Massive earthquakes often cause structures to collapse, trapping victims under dense rubble for long periods of time. Commonly, this spurs resource intensive, dangerous, and frustrating attempts to find and extricate live victims. The search and rescue phase usually is maintained for many days beyond the last "save," potentially diverting critical attention and resources away from the pressing needs of non-trapped survivors and the devastated community. This recurring phenomenon is driven by the often-unanswered question "Can anyone still be alive under there?" The maximum survival time in entrapment is an important issue for responders, yet little formal research has been conducted on this issue. Knowing the maximum survival time in entrapment helps responders: (1) decide whether or not they should continue to assign limited resources to search and rescue activities; (2) assess the safety risks versus the benefits; (3) determine when search and rescue activities no longer are indicated; and (4) time and pace the important transition to community recovery efforts. ⋯ A thorough search of the English-language medical literature and media accounts provides a provocative picture of numerous survivors beyond 48 hours of entrapment under rubble, with a few successfully enduring entrapment of 13-14 days. These data are not necessarily applicable to non-earthquake collapsed-structure events. For incident managers and their medical advisors, the study findings and discussion may be useful for post-impact decision-making and in establishing and/or revising incident priorities as the response evolves.

Precision of in-hospital triage in mass-casualty incidents after terror attacks.
Proper management of mass-casualty incidents (MCIs) relies on triage as a critical component of the disaster plan. ⋯ Primary triage, even when carried out by experienced trauma physicians, can be unreliable in a MCI.

The disaster caused by the tsunami of 26 December 2004 was one of the worst that medical systems have faced. The aim of this study was to learn about the medical response of the Thai hospitals to this disaster and to establish guidelines that will help hospitals prepare for future disasters. The Israeli Defense Forces (IDF) Home Front Command (HFC) Medical Department sent a research delegation to Thai hospitals to study: (1) pre-event hospital preparedness; (2) patient evacuation and triage; (3) personnel and equipment reinforcement; (4) modes used for alarm and recruitment of hospital personnel; (5) internal reorganization of hospitals; and (6) admission, discharge, and secondary transfer (forward management) of patients. ⋯ Although preparedness was deficient, hospital systems performed well. Disaster management should focus on field-based first aid and triage, and rapid evacuation to secondary hospitals. Additionally, disaster management should reinforce and rely on the existing and well-trusted medical system.

Although the need for on-site physicians at mass gatherings has been investigated in developed countries, it has not been studied in a developing country, where resources are limited, paramedical services are unavailable, and transportation and other facilities are inadequate. ⋯ The presence of on-site physicians at a major sporting event resulted in the majority of injuries and complaints being effectively treated on-scene. This reduced the number of hospital referrals and saved time and money for treatment.
