Pediatric-Specific Hazard Vulnerability Analysis: The Missing Component of Regional and Hospital-Based Preparedness

Though children comprise a large percentage of the population and are uniquely vulnerable to disasters, pediatric considerations are often omitted from regional and hospital-based emergency preparedness. Children's absence is particularly notable in hazard vulnerability analyses (HVAs), a commonly used tool that allows emergency managers to identify a hazard's impact, probability of occurrence, and previous mitigation efforts. This paper introduces a new pediatric-specific HVA that provides emergency managers with a quantifiable means to determine how a hazard might affect children within a given region, taking into account existing preparedness most relevant to children's safety. Impact and preparedness categories within the pediatric-specific HVA incorporate age-based equipment and care needs, long-term developmental and mental health consequences, and the hospital and community functions most necessary for supporting children during disasters. The HVA allows emergency managers to create a more comprehensive assessment of their pediatric populations and preparatory requirements.

Lessons learned from reviewing a hospital's disaster response to the hydrofluoric acid leak in Gumi city in 2012

Background

This study analyzed the characteristics of hydrogen fluoride-exposed patients (HFEPs) treated in the emergency department (ED) of a local university hospital, and reviewed the hospital’s disaster response according to space, staff, supplies, and systems (4Ss).

Methods

This retrospective observational chart review and descriptive study included 199 HFEPs among 2588 total ED patients who visited a local university emergency medical center for treatment between September 27, 2012 and October 20, 2012, following a hydrofluoric acid leak at the Hube Globe factory in Gumi City, Republic of Korea. Descriptive results concerning the 4Ss were obtained by interviewing ED specialist staff physicians on duty during the study period. In accordance with American Burn Association criteria, patients requiring burn center referral were assigned to the major burn group (MBG) as severe condition.

Results

During the acute phase (within 8 h after leak initiation), there were 43 patients in the ED, which was staffed with 3 doctors and 3 nurses, without 4S resources. Of these 43 patients, there were 8 HFEPs (100%) in the MBG and 0 in the non-MBG (NMBG). During the subacute phase (24 h after the acute phase), there were 262 patients in the ED including 167 HFEPs, of whom 45 (26.95%) were in the MBG and 122 (73.05%) were in the NMBG. The ED was then staffed with 6 doctors (3 on day shift and 3 on night shift) and 10 nurses (3 on day shift, 4 on evening shift, and 3 on night shift), and no 4S resources were available. Throughout the study period, no 4Ss were available. First, there was no expansion of ED space or secured disaster reserve beds. Second, there was no increase in manpower with duty time adjustments or duty relocation for ED working personnel. Third, there was no logistics reinforcement (e.g., antidote or personal protective equipment). Fourth, there were no disaster-related measures for the administration department, decontamination zone setup, safety diagnostic testing, or designated disaster triage implementation.

Conclusions

The hospital’s disaster response was insufficient for all aspects of the 4Ss. Detailed guidance concerning a hospital disaster management plan is required.

Population Health Adaptation Approaches to the Increasing Severity and Frequency of Weather-Related Disasters Resulting From our Changing Climate: A Literature Review and Application to Charleston, South Carolina

PURPOSE OF REVIEW

Recent changes in our planetary climate have and will continue to challenge historical knowledge and risk assumptions for weather-related disasters. While the public health community is rapidly working to develop epidemiological approaches and tools to mitigate and adapt to these weather-related disasters, recent high-profile events have exposed gaps in knowledge and response efforts. Limited work has been done to assess the climate readiness of the local public health and healthcare community as it pertains to local response planning and adaptation measures in the event of a weather-related disaster. The purpose of this paper is to review the existing literature related to climate change, weather-related disasters, and population health approaches to adapt to climate-related changes in weather-related disasters at the local level. We highlight a brief case study to illustrate an example of a local approach to adaptation planning in a coastal community.

RECENT FINDINGS

Few studies have put forth quantitative disaster epidemiology tools to aid public health officials in preparing for and responding to these weather-related disaster events. There is a general lack of understanding within the public health community about the epidemiological tools which are available to assist local communities in their preparation for, response to, and recovery from weather-related disasters. Cities around the nation are already working to assess their vulnerability and resilience to weather-related disasters by including climate change in emergency preparedness plans and developing adaptation strategies, as well as equipping local hospitals, health departments and other critical public health systems with climate information. But more work is needed and public health funding is lagging to support local and state-level efforts in preparing for and adapting to weather-related disasters in the context of a changing climate. Our population health disaster preparedness programs need to be adapted to address the increasing risks to local public health resulting from our changing climate.

The role of hazard vulnerability assessments in disaster preparedness and prevention in China

China is prone to disasters and escalating disaster losses. Effective disaster mitigation is the foundation for efficient disaster response and rescue and for reducing the degree of hazardous impacts on the population. Vulnerability refers to the population's capacity to anticipate, cope with, and recover from the impact of a hazardous event. A hazard vulnerability assessment (HVA) systematically evaluates the damage that could be caused by a potential disaster, the severity of the impact, and the available medical resources during a disaster to reduce population vulnerability and increase the capacity to cope with disasters. In this article, we summarized HVA team membership, content (disaster identification, probability and consequences), and methods and procedures for an HVA that can be tailored to China's needs. We further discussed the role of epidemiology in an HVA. Disaster epidemiology studies the underlying causes of disasters to achieve effective disaster prevention and reduction. In addition, we made several recommendations that are already in practice in developed countries, such as the U.S., for future implementation in China and other developing countries. An effective HVA plan is crucial for successful disaster preparedness, response, and recovery.

Health care system hazard vulnerability analysis: an assessment of all public hospitals in Abu Dhabi

Hazard vulnerability analysis (HVA) is used to risk-stratify potential threats, measure the probability of those threats, and guide disaster preparedness. The primary objective of this project was to analyse the level of disaster preparedness in public hospitals in the Emirate of Abu Dhabi, utilising the HVA tool in collaboration with the Disaster Medicine Section at Harvard Medical School. The secondary objective was to review each facility's disaster plan and make recommendations based on the HVA findings. Based on the review, this article makes eight observations, including on the need for more accurate data; better hazard assessment capabilities; enhanced decontamination capacities; and the development of hospital-specific emergency management programmes, a hospital incident command system, and a centralised, dedicated regional disaster coordination centre. With this project, HVAs were conducted successfully for the first time in health care facilities in Abu Dhabi. This study thus serves as another successful example of multidisciplinary emergency preparedness processes.
