Rinsing only with water or washing with soap and water are common methods of skin decontamination for skin contaminated during a chemical hazard release. The null hypothesis was that a 15-minute water irrigation (decontamination method 1) would not be superior to decontamination using a microfiber towel, followed by a wet wipe (Signature Select Softly Flushable Tissue Better Living Brands LLC, Pleasanton, CA), followed by using another microfiber towel (decontamination method 2).

A simulated contaminant (Magic Fluorescent Glow Paint for Face and Body, iLC Shenzhen Fulimei Technology Co. LTD, Shenzhen, the People’s Republic of China) was applied to the dorsal skin of each subject’s forearms. Then, photographs of these subject’s skin were taken before and after decontamination of the simulated contaminant by using either decontamination method 1 or 2. Each of the subjects underwent both decontamination methods in separate trials, with each subject using one forearm for decontamination method 1 and their other forearm for decontamination method 2. Discrete points of contamination were quantified on the photographs that were taken with the skin illuminated by ambient visible light or ultraviolet light (395nm, Roceei ultraviolet flashlight, China).

Under visible light, no residual contamination was seen by inspecting photographs taken after decontaminating with either method. Under ultraviolet light, less visible contamination was seen by inspecting photographs taken after decontaminating with method 1 than after decontaminating with method 2.

In this study, skin decontamination with water irrigation was superior to skin decontamination without water irrigation.

The objective of this investigation was to examine the health impact of and medical response to a mass casualty chemical incident caused by a vinyl chloride release.

Key staff at area hospitals were interviewed about communication during the response, the number of patients treated and care required, and lessons learned. Clinical information related to the incident and medical history were abstracted from hospital charts.

Hospital interviews identified a desire for more thorough and timely incident-specific information and an under-utilization of regionally available resources. Two hundred fifty-six hospital visits (96.2%) were at the facility closest to the site of the derailment. Of 237 initial visits at which the patient was examined by a physician, 231 patients (97.5%) were treated in the emergency department (ED) and 6 patients (2.5%) were admitted; 5 admitted patients (83.3%) had preexisting medical conditions. Thirteen of 14 asymptomatic ED patients were children under the age of 10 years. One hundred forty-five patients (62.8%) discharged from the ED were diagnosed solely with exposure to vinyl chloride.

Continuous emergency response planning might facilitate communication and better distribution of patient surge across hospitals. Individuals with multiple medical conditions and parents and caretakers of children may serve as target groups for risk communication following acute chemical releases.

We designed and conducted a regional full-scale exercise in 2007 to test the ability of Atlanta-area hospitals and community partners to respond to a terrorist attack involving the coordinated release of 2 dangerous chemicals (toluene diisocyanate and parathion) that were being transported through the area by tanker truck.

The exercise was designed to facilitate the activation of hospital emergency response plans and to test applicable triage, decontamination, and communications protocols. Plume modeling was conducted by using the Defense Threat Reduction Agency’s (DTRA) Hazard Prediction and Assessment Capability (HPAC) V4 program. The scenario went through multiple iterations as exercise planners sought to reduce total injuries to a manageable, but stressful, level for Atlanta’s health care infrastructure.

Atlanta-area hospitals rapidly performed multiple casualty triage and were able to take in a surge of victims from the simulated attack. However, health care facilities were reticent to push the perceived manageable numbers of victims, and scenarios were modified significantly to lower the magnitude of the simulated attack. Additional coordination with community response partners and incident command training is recommended. Security at health care facilities and decontamination of arriving victims are two areas that will require continued review.

Atlanta-area hospitals participated in an innovative regional exercise that pushed facilities beyond traditional scopes of practice and brought together numerous health care community response partners. Using lessons learned from this exercise coupled with subsequent real-world events and training exercises, participants have significantly enhanced preparedness levels and increased the metropolitan region’s medical surge capacity in the case of a multiple casualty disaster.

To provide a more comprehensive view than previously available of US physician preparedness for public health emergencies, this study examined physicians’ assessments of their preparedness, training, participation in institutional activities, information practices, and experiences with patient education. Four kinds of public health emergencies were considered: natural disasters, major airborne infections, major foodborne illness outbreaks, and chemical, biological, radiological, nuclear, or explosives (CBRNE) incidents.

Between October 19, 2011, and January 11, 2012, researchers conducted a national poll among 1603 practicing physicians in a range of specialties in hospital and nonhospital settings.

More than one-half of physicians felt prepared to handle a natural disaster, a major outbreak of an airborne infection, or a major foodborne illness outbreak, whereas one-third (34%) felt prepared to handle a CBRNE incident. About one-half of physicians (55%) had participated in training or a conference related to emergencies in the past 2 years. Sizable fractions of physicians were unaware of emergency response tools in their care setting. For example, nearly one-half in hospitals (44%) did not know whether their care setting had an emergency response plan, and less than one-quarter had participated in a drill using such a plan in the past 2 years. Less than one-third (31%) of physicians had signed up to receive alerts in the case of future emergencies. One in 10 reported sharing emergency information with patients at least “sometimes.”

Significant gaps remain in physician preparedness for public health emergencies, as well as in related training and participation in institutional activities. New efforts, with a focus on possible collaborations between public health institutions and health system leaders combined with effective use of online resources, are needed to bring more physicians on board and to develop relevant and useful key tools. New approaches, including those that rely on different types of care providers, may be needed to enhance patient education regarding emergency preparedness.

The objective of this study was to draft a new Japanese Disaster Medical Assistance Team (DMAT) training program based on the responses to the Great East Japan Earthquake.

Working group members of the Japan DMAT Investigative Commission, Ministry of Health, Labour and Welfare, reviewed reports and academic papers on DMAT activities after the disaster and identified items in the current Japanese DMAT training program that should be changed. A new program was proposed that incorporates these changes.

New topics that were identified to be added to the DMAT training program were hospital evacuation, preparations to receive DMATs at damaged hospitals, coordination when DMAT activities are prolonged, and safety management and communication when on board small helicopters. The use of wide-area transport was reviewed and changes were made to cover selection of various transport means including helicopter ambulances. Content related to confined space medicine was removed. The time spent on emergency medical information system (EMIS) practical training was increased. Redundant or similar content was combined and reorganized, and a revised DMAT training program that did not increase the overall training time was designed.

The revised DMAT training program will provide practical training better suited to the present circumstances in Japan. (Disaster Med Public Health Preparedness. 2014;8:477-484)
