During emergency responses, public health leaders frequently serve in incident management roles that differ from their routine job functions. Leaders’ familiarity with incident management principles and functions can influence response outcomes. Therefore, training and exercises in incident management are often required for public health leaders. To describe existing methods of incident management training and exercises in the literature, we queried 6 English language databases and found 786 relevant articles. Five themes emerged: (1) experiential learning as an established approach to foster engaging and interactive learning environments and optimize training design; (2) technology-aided decision support tools are increasingly common for crisis decision-making; (3) integration of leadership training in the education continuum is needed for developing public health response leaders; (4) equal emphasis on competency and character is needed for developing capable and adaptable leaders; and (5) consistent evaluation methodologies and metrics are needed to assess the effectiveness of educational interventions.

These findings offer important strategic and practical considerations for improving the design and delivery of educational interventions to develop public health emergency response leaders. This review and ongoing real-world events could facilitate further exploration of current practices, emerging trends, and challenges for continuous improvements in developing public health emergency response leaders.

Indexed literature (from 2015 to 2020) on artificial intelligence (AI) technologies and machine learning algorithms (ML) pertaining to disasters and public health emergencies were reviewed. Search strategies were developed and conducted for PubMed and Compendex. Articles that met inclusion criteria were filtered iteratively by title followed by abstract review and full text review. Articles were organized to identify novel approaches and breadth of potential AI applications. A total of 1217 articles were initially retrieved by the search. Upon relevant title review, 1003 articles remained. Following abstract screening, 667 articles remained. Full text review for relevance yielded 202 articles. Articles that met inclusion criteria totaled 56 articles. Those identifying specific roles of AI and ML (17 articles) were grouped by topics highlighting utility of AI and ML in disaster and public health emergency contexts. Development and use of AI and ML have increased dramatically over the past few years. This review discusses and highlights potential contextual applications and limitations of AI and ML in disaster and public health emergency scenarios.

Effective preparedness, response, and recovery from disasters require a well-planned, integrated effort with experienced professionals who can apply specialized knowledge and skills in critical situations. While some professionals are trained for this, others may lack the critical knowledge and experience needed to effectively perform under stressful disaster conditions. A set of clear, concise, and precise training standards that may be used to ensure workforce competency in such situations has been developed. The competency set has been defined by a broad and diverse set of leaders in the field and like-minded professionals through a series of Web-based surveys and expert working group meetings. The results may provide a useful starting point for delineating expected competency levels of health professionals in disaster medicine and public health.

Background: Various organizations and universities have developed competencies for health professionals and other emergency responders. Little effort has been devoted to the integration of these competencies across health specialties and professions. The American Medical Association Center for Public Health Preparedness and Disaster Response convened an expert working group (EWG) to review extant competencies and achieve consensus on an educational framework and competency set from which educators could devise learning objectives and curricula tailored to fit the needs of all health professionals in a disaster.

Methods: The EWG conducted a systematic review of peer-reviewed and non–peer reviewed published literature. In addition, after-action reports from Hurricane Katrina and relevant publications recommended by EWG members and other subject matter experts were reviewed for congruencies and gaps. Consensus was ensured through a 3-stage Delphi process.

Results: The EWG process developed a new educational framework for disaster medicine and public health preparedness based on consensus identification of 7 core learning domains, 19 core competencies, and 73 specific competencies targeted at 3 broad health personnel categories.

Conclusions: The competencies can be applied to a wide range of health professionals who are expected to perform at different levels (informed worker/student, practitioner, leader) according to experience, professional role, level of education, or job function. Although these competencies strongly reflect lessons learned following the health system response to Hurricane Katrina, it must be understood that preparedness is a process, and that these competencies must be reviewed continually and refined over time.

Objectives: US hospitals are expected to function without external aid for up to 96 hours during a disaster; however, concern exists that there is insufficient capacity in hospitals to absorb large numbers of acute casualties. The aim of the study was to determine the potential for creation of inpatient bed surge capacity from the early discharge (reverse triage) of hospital inpatients at low risk of untoward events for up to 96 hours.

Methods: In a health system with 3 capacity-constrained hospitals that are representative of US facilities (academic, teaching affiliate, community), a variety (N = 50) of inpatient units were prospectively canvassed in rotation using a blocked randomized design for 19 weeks ending in February 2006. Intensive care units (ICUs), nurseries, and pediatric units were excluded. Assuming a disaster occurred on the day of enrollment, patients who did not require any (previously defined) critical intervention for 4 days were deemed suitable for early discharge.

Results: Of 3491 patients, 44% did not require any critical intervention and were suitable for early discharge. Accounting for additional routine patient discharges, full use of staffed and unstaffed licensed beds, gross surge capacity was estimated at 77%, 95%, and 103% for the 3 hospitals. Factoring likely continuance of nonvictim emergency admissions, net surge capacity available for disaster victims was estimated at 66%, 71%, and 81%, respectively. Reverse triage made up the majority (50%, 55%, 59%) of surge beds. Most realized capacity was available within 24 to 48 hours.

Conclusions: Hospital surge capacity for standard inpatient beds may be greater than previously believed. Reverse triage, if appropriately harnessed, can be a major contributor to surge capacity. (Disaster Med Public Health Preparedness. 2009;3(Suppl 1):S10–S16)

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. Adopting this approach will ensure that disaster response activities will occur in a comprehensive fashion that minimizes the patient care burden at each subsequent order of intervention and reduces the overall need to ration care. The seamless integration of all orders of intervention within this systems-based model of disaster-specific triage, coordinated through health emergency operations centers, can ensure that disaster response measures are undertaken in a manner that is effective, just, and equitable. (Disaster Med Public Health Preparedness. 2008;2(Suppl 1):S35–S39)

There is no widely accepted, validated framework of health care emergency management capabilities (HEMCs) that can be used by facilities to guide their disaster preparedness and response efforts. We reviewed the HEMCs and the evaluation methods used by the Veterans Health Administration, The Joint Commission, the Institute of Medicine Metropolitan Medical Response System committee, the Department of Homeland Security, and the Department of Health and Human Services to determine whether a core set of HEMCs and evaluative methods could be identified.

Despite differences in the conceptualization of health care emergency management, there is considerable overlap among the agencies regarding major capabilities and capability-specific elements. Of the 5 agencies, 4 identified occupant safety and continuity of operations as major capabilities. An additional 5 capabilities were identified as major by 3 agencies. Most often the differences were related to whether a capability should be a major one versus a capability-specific element (eg, decontamination, management of resources). All of the agencies rely on multiple indicators and data sources to evaluate HEMCs. Few performance-based tools have been developed and none have been fully tested for their reliability and validity. Consensus on a framework and tools to measure HEMCs is needed. (Disaster Med Public Health Preparedness. 2009;3(Suppl 1):S45–S51)

Introduction: On August 29, 2005, Hurricane Katrina made landfall along the US Gulf Coast, resulting in the evacuation of >1.5 million people, including nearly 6000 physicians. This article examines the relocation patterns of physicians following the storm, determines the impact that the disaster had on their lives and practices, and identifies lessons learned.

Methods: An Internet-based survey was conducted among licensed physicians reporting addresses within Federal Emergency Management Agency–designated disaster zones in Louisiana and Mississippi. Descriptive data analysis was used to describe respondent characteristics. Multivariate logistic regression was performed to identify the factors associated with physician nonreturn to original practice. For those remaining relocated out of state, bivariate analysis with χ2 or Fisher exact test was used to determine factors associated with plans to return to original practice.

Results: A total of 312 eligible responses were collected. Among disaster zone respondents, 85.6% lived in Louisiana and 14.4% resided in Mississippi before the hurricane struck. By spring 2006, 75.6% (n = 236) of the respondents had returned to their original homes, whereas 24.4% (n = 76) remained displaced. Factors associated with nonreturn to original employment included family or general medicine practice (OR 0.42, 95% CI 0.17–1.04; P = .059) and severe or complete damage to the workplace (OR 0.24, 95% CI 0.13–0.42; P < .001).

Conclusions: A sizeable proportion of physicians remain displaced after Hurricane Katrina, along with a lasting decrease in the number of physicians serving in the areas affected by the disaster. Programs designed to address identified physician needs in the aftermath of the storm may give confidence to displaced physicians to return. (Disaster Med Public Health Preparedness. 2007;1:21–26)

Background: Although the training of future physicians in disaster preparedness and public health issues has been recognized as an important component of graduate medical education, medical students receive relatively limited exposure to these topics. Recommendations have been made to incorporate disaster medicine and public health preparedness into medical school curricula. To date, the perspectives of future physicians on disaster medicine and public health preparedness issues have not been described.

Methods: A Web-based survey was disseminated to US medical students. Frequencies, proportions, and odds ratios were calculated to assess perceptions and self-described likelihood to respond to disaster and public health scenarios.

Results: Of the 523 medical students who completed the survey, 17.2% believed that they were receiving adequate education and training for natural disasters, 26.2% for pandemic influenza, and 13.4% for radiological events, respectively; 51.6% felt they were sufficiently skilled to respond to a natural disaster, 53.2% for pandemic influenza, and 30.8% for radiological events. Although 96.0% reported willingness to respond to a natural disaster, 93.7% for pandemic influenza, and 83.8% for a radiological event, the majority of respondents did not know to whom they would report in such an event.

Conclusions: Despite future physicians' willingness to respond, education and training in disaster medicine and public health preparedness offered in US medical schools is inadequate. Equipping medical students with knowledge, skills, direction, and linkages with volunteer organizations may help build a capable and sustainable auxiliary workforce.

Objective: The potential for deadly human stampedes to occur at any mass gathering event highlights this unique form of crowd disaster as deserving of special attention from both scientific and planning perspectives. Improved understanding of human stampedes is indispensable in the mitigation of this type of mass casualty. With relatively few peer-reviewed reports on deadly human stampedes, information from news reports and the Internet is essential to increased collective understanding. Without incorporating nontraditional sources, no other way to reasonably acquire sufficient data is available. This study analyzed human stampede events from 1980 to 2007 to identify epidemiological characteristics associated with increased mortality.

Methods: A LexisNexis search was followed by sequential searches of multiple Internet-based English-language news agencies. Date, country, geographical region, time of occurrence, type of event, location, mechanism, number of participants, number injured, and number of deaths were recorded. Bivariate analyses of number of deaths or injuries were conducted using a nonparametric Wilcoxon rank test. Multivariate regression was performed to determine the factors associated with increased number of fatalities during stampede events.

Results: A total of 215 human stampede events were reported from 1980 to 2007, resulting in 7069 deaths and at least 14,078 injuries from 213 events with available fatality information and 179 events with injury information. In bivariate analysis, stampedes occurring in the Middle East, in developing countries, outdoors, or associated with religious events had the highest median number of deaths. In multivariate analysis, events that occurred in developing countries and outdoors were associated with increased number of fatalities. Stampedes that occurred in the context of sports, religious, music, and political events, or that had a unidirectional mechanism, also increased the relative number of deaths.

Conclusions: Several epidemiological features of human stampedes associated with increased mortality are identified. Standardized collection of epidemiological data pertaining to human stampedes is strongly recommended, and further study of this recurrent, distinctive disaster is warranted.

The incident command system provides an organizational structure at the agency, discipline, or jurisdiction level for effectively coordinating response and recovery efforts during most conventional disasters. This structure does not have the capacity or capability to manage the complexities of a large-scale health-related disaster, especially a pandemic, in which unprecedented decisions at every level (eg, surveillance, triage protocols, surge capacity, isolation, quarantine, health care staffing, deployment) are necessary to investigate, control, and prevent transmission of disease. Emerging concepts supporting a unified decision-making, coordination, and resource management system through a health-specific emergency operations center are addressed and the potential structure, function, roles, and responsibilities are described, including comparisons across countries with similar incident command systems.

Objectives: The southern California wildfires in autumn 2007 resulted in widespread disruption and one of the largest evacuations in the state’s history. This study aims to identify unmet medical needs and health care–seeking patterns as well as prevalence of acute and chronic disease among displaced people following the southern California wildfires. These data can be used to increase the accuracy, and therefore capacity, of the medical response.

Methods: A team of emergency physicians, nurses, and epidemiologists conducted surveys of heads of households at shelters and local assistance centers in San Diego and Riverside counties for 3 days beginning 10 days postdisaster. All households present in shelters on the day of the survey were interviewed, and at the local assistance centers, a 2-stage sampling method was used that included selecting a sample size proportionate to the number of registered visits to that site compared with all sites followed by a convenience sampling of people who were not actively being aided by local assistance center personnel. The survey covered demographics; needs following the wildfires (shelter, food, water, and health care); acute health symptoms; chronic health conditions; access to health care; and access to prescription medications.

Results: Among the 175 households eligible, 161 (92.0%) households participated. Within the 47 households that reported a health care need since evacuation, 13 (27.7%) did not receive care that met their perceived need. Need for prescription medication was reported by 47 (29.2%) households, and 20 (42.6%) of those households did not feel that their need for prescription medication had been met. Mental health needs were reported by 14 (8.7%) households with 7 of these (50.0%) reporting unmet needs. At least 1 family member per household left prescription medication behind during evacuation in 46 households (28.6%), and 1 family member in 48 households (29.8%) saw a health care provider since their evacuation. Most people sought care at a clinic (24, 50.0%) or private doctor (11, 22.9%) as opposed to an emergency department (6, 12.5%).

Conclusions: A significant portion of the households reported unmet health care needs during the evacuations of the southern California wildfires. The provision of prescription medication and mental health services were the most common unmet need. In addition, postdisaster disease surveillance should include outpatient and community clinics, given that these were the most common treatment centers for the displaced population.

The tragic nature of the human stampede that took place in Phnom Penh, Cambodia on November 22, 2010 claimed the lives of 347 people during the three-day-long Water Festival, known as Bon Om Touk. Described as the greatest tragedy that Cambodia has experienced since the collapse of the Khmer Rouge, the Bon Om Touk stampede ranks among the deadliest human stampede disasters during the past 30 years, a Class IV event exceeding 100 fatalities according to a recently proposed scale.1 From the perspective of global health, the event shares many characteristics with preceding major crowd disasters and failures in event planning. It is essential for the international community to officially monitor human stampedes as it does other major disasters. Additional research on human stampedes is needed to improve our collective understanding of the causes of crowd disasters and how best to prevent them.
