Public Health Emergency Response Leadership Training: A Qualitative Assessment of Existing Educational Opportunities and Perceived Facilitators, Barriers, and Priorities in Professional Development.

OBJECTIVE: We aimed to understand the current training environment for developing public health emergency response leaders and highlight facilitators and barriers in accessing targeted training. DESIGN: We designed 4 focus groups to gather organizational perspectives on public health emergency response leadership development. Discussions were recorded, transcribed, coded, and analyzed to synthesize key themes. SETTING: Focus groups were convened at the 2019 Preparedness Summit (March 27-28) in St Louis, Missouri. PARTICIPANTS: Twenty-three public health professionals from 9 Public Health Emergency Preparedness (PHEP) Cooperative Agreement award recipient jurisdictions and 12 local health departments participated. MAIN OUTCOME MEASURES: We examined the current availability, relevance, specificity, and utility of educational content and delivery modalities. Facilitators and barriers were identified as opportunities to improve training access. RESULTS: Generic emergency management training is considered important and widely available but with limited application in public health practice. Existing leadership training opportunities in public health emergency response are limited and not widely known. While organizational support and accessible training facilitate participation, resource constraints (ie, funding, time, and staff) exist as key barriers. In addition, frequent staff turnover and attrition that result in loss of institutional knowledge likely hinder effective public health emergency responses. CONCLUSION: Effective public health emergency response depends on capable leaders not only well versed in specialized technical disciplines and practices but also familiar with-or preferably fluent in-emergency management principles and functions. This study demonstrated that well-aimed training strategies and organizational planning are essential in developing public health emergency response leaders. Specifically, leadership development may accrue considerable benefit from a standardized training curriculum. In addition, scalable training programs developed through public, private, and academic partnerships may lessen resource demands on individual organizations to facilitate training access. Finally, training practicums (eg, mentoring, shadowing) may provide opportunities to facilitate active learning and preserve institutional knowledge through leadership transitions.

Pilgrim Satisfaction in a Mass Religious Gathering: Study from Sabarimala Destination, Kerala State of India.

Identification of basic factors of pilgrim satisfaction is essential to responsive authorities for effective implementation of devotee welfare programmes. The determinants of satisfaction in a particular location are comprised of environmental, economic and sociocultural activities. The Sabarimala hill temple is one of the major Sastha temples in India. Every year, about 25 million pilgrims visit the temple from all parts of the country and abroad. The present study analyzes devotee satisfaction according to their demographic profile and identifies key factors that affect the overall satisfaction of pilgrims visiting the temple at the Sabarimala mass gathering destination. A total of 526 visitors were contacted with a prestructured, field tested questionnaire. This was analyzed using the Statistical Package for Social Sciences. Factor analysis, regression analysis and two-step cluster analysis were used to elucidate satisfaction parameters. The identified factor groupings for pilgrim satisfaction at Sabarimala destination are food and accommodation, safety and security, health and sanitation, ecology and environment and and communication and transportation. From the analysis of various results of the present study, it is evident that the mass pilgrimage of Sabarimala destination exhibits the signs of a secular experience and its visitors are mainly motivated by spiritual aspects.

A standardized protocol using clinical adjudication to define true infection status in patients presenting to the emergency department with suspected infections and/or sepsis.

In absence of a "gold standard", a standardized clinical adjudication process was developed for a registrational trial of a transcriptomic host response (HR) test. Two physicians independently reviewed clinical data to adjudicate presence and source of bacterial and viral infections in emergency department patients. Discordant cases were resolved by a third physician. Agreement among 955 cases was 74.1% (708/955) for bacterial, 75.6% (722/955) for viral infections, and 71.2% (680/955) overall. Most discordances were minor (85.2%; 409/480) versus moderate (11.7%; 56/480) or complete (3.3%; 16/480). Concordance levels were lowest for bacterial skin and soft tissue infections (8.2%) and for viral respiratory tract infections (4.5%). This robust adjudication process can be used to evaluate HR tests and other diagnostics by regulatory agencies and for educating clinicians, laboratorians, and clinical researchers. Clinicaltrials.gov NCT04094818. SUMMARY: Without a gold standard for evaluating host response tests, clinical adjudication is a robust reference standard that is essential to determine the true infection status in diagnostic registrational clinical studies.

Modernized Crowd Counting Strategies for Mass Gatherings-A Review.

Estimation of crowd size for large gatherings is an indispensable metric for event planners, local authorities, and emergency management. Currently, most crowd counting relies on dated methods such as people counters, entrance sensors, and ticket sales. Over the past decade, there has been rapid development in crowd counting techniques and related technology. Despite progress, theoretical advances in crowd counting technology have outpaced practical applications. The emergence of the vast array of crowd counting techniques has added to the challenge of determining those advances that can be most readily implemented. This article aims to provide an overview of promising crowd counting strategies and recent developments applied within the disaster medicine context along with the best use cases and limitations.

A review of infectious disease epidemiology in emergency medical service clinicians.

BACKGROUND: The emergency medical service (EMS) workforce is at high risk of occupationally-acquired infections. This review synthesized existing literature on the prevalence, incidence, and severity of infections in the EMS workforce. METHODS: We searched PubMed, Embase, CINAHL, and SCOPUS from January 1, 2006 to March 15, 2022 for studies in the US that involved EMS clinician or firefighter populations and reported 1 or more health outcomes related to occupationally-acquired infections. RESULTS: Of the 25 studies that met the inclusion criteria, most focused on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, with prevalence rates ranging from 1.1% to 36.2% (median 6.7%). The prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in 4 studies ranged from 1.9% to 6.4%, and the prevalence of Hepatitis C in 1 study was 1.3%. Few studies reported incidence rates. The prevalence or incidence of these infections generally did not differ by age or gender, but 4 studies reported differences by race or ethnicity. In the 4 studies that compared infection rates between EMS clinicians and firefighters, EMS clinicians had a higher chance of hospitalization or death from SAR-CoV-2 (odds ratio 4.23), a higher prevalence of Hepatitis C in another study (odds ratio 1.74), and no significant difference in MRSA colonization in a separate study. CONCLUSIONS: More research is needed to better characterize the incidence and severity of occupationally-acquired infections in the EMS workforce.

Current Evidence for Infection Prevention and Control Interventions in Emergency Medical Services: A Scoping Review.

OBJECTIVES: The aim of this review was to summarize current evidence from the United States on the effectiveness of practices and interventions for preventing, recognizing, and controlling occupationally acquired infectious diseases in Emergency Medical Service (EMS) clinicians. REPORT AND METHODS: PubMed, Embase, CINAHL, and SCOPUS were searched from January 1, 2006 through March 15, 2022 for studies in the United States that involved EMS clinicians and firefighters, reported on one or more workplace practices or interventions that prevented or controlled infectious diseases, and included outcome measures. Eleven (11) observational studies reported on infection prevention and control (IPC) practices providing evidence that hand hygiene, standard precautions, mandatory vaccine policies, and on-site vaccine clinics are effective. Less frequent handwashing (survey-weight adjusted odds ratio [OR] 4.20; 95% confidence interval [CI], 1.02 to 17.27) and less frequent hand hygiene after glove use (survey-weight adjusted OR 10.51; 95% CI, 2.54 to 43.45) were positively correlated with nasal colonization of Methicillin-resistant Staphylococcus aureus (MRSA). Lack of personal protective equipment (PPE) or PPE breach were correlated with higher severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seropositivity (unadjusted risk ratio [RR] 4.2; 95% CI, 1.03 to 17.22). Workers were more likely to be vaccinated against influenza if their employer offered the vaccine (unadjusted OR 3.3; 95% CI, 1.3 to 8.3). Active, targeted education modules for H1N1 influenza were effective at increasing vaccination rates and the success of on-site vaccine clinics. CONCLUSIONS: Evidence from the United States exists on the effectiveness of IPC practices in EMS clinicians, including hand hygiene, standard precautions, mandatory vaccine policies, and vaccine clinics. More research is needed on the effectiveness of PPE and vaccine acceptance.

Comparative study of encoded and alignment-based methods for virus taxonomy classification.

The emergence of viruses and their variants has made virus taxonomy more important than ever before in controlling the spread of diseases. The creation of efficient treatments and cures that target particular virus properties can be aided by understanding virus taxonomy. Alignment-based methods are commonly used for this task, but are computationally expensive and time-consuming, especially when dealing with large datasets or when detecting new virus variants is time sensitive. An alternative approach, the encoded method, has been developed that does not require prior sequence alignment and provides faster results. However, each encoded method has its own claimed accuracy. Therefore, careful evaluation and comparison of the performance of different encoded methods are essential to identify the most accurate and reliable approach for virus taxonomy classification. This study aims to address this issue by providing a comprehensive and comparative analysis of the potential of encoded methods for virus classification and phylogenetics. We compared the vectors generated for each encoded method using distance metrics to determine their similarity to alignment-based methods. The results and their validation show that K-merNV followed by CgrDft encoded methods, perform similarly to state-of-the-art multi-sequence alignment methods. This is the first study to incorporate and compare encoded methods that will facilitate future research in making more informed decisions regarding selection of a suitable method for virus taxonomy.

A Scoping Review of the Essential Components of Emergency Medical Response Systems for Mass Casualty Incidents.

OBJECTIVE: Emergency medical (EM) response systems require extensive coordination, particularly during mass casualty incidents (MCIs). The recognition of preparedness gaps and contextual priorities to MCI response capacity in low- and middle-income countries (LMICs) can be better understood through the components of EM reponse systems. This study aims to delineate essential components and provide a framework for effective emergency medical response to MCIs. METHODS: A scoping review was conducted using 4 databases. Title and abstract screening was followed by full-text review. Thematic analysis was conducted to identify themes pertaining to the essential components and integration of EM response systems. RESULTS: Of 20,456 screened citations, 181 articles were included in the analysis. Seven major and 40 sub-themes emerged from the content analysis as the essential components and supportive elements of MCI medical response. The essential components of MCI response were integrated into a framework demonstrating interrelated connections between essential and supportive elements. CONCLUSIONS: Definitions of essential components of EM response to MCIs vary considerably. Most literature pertaining to MCI response originates from high income countries with far fewer reports from LMICs. Integration of essential components is needed in different geopolitical and economic contexts to ensure an effective MCI emergency medical response.

Cambodian Bon Om Touk stampede highlights preventable tragedy.

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. Hsu EB , Burkle FM Jr .

Disaster curricula in medical education: pilot survey.

INTRODUCTION: An understanding of disaster medicine and the health care system during mass-casualty events is vital to a successful disaster response, and has been recommended as an integral part of the medical curriculum by the Association of American Medical Colleges (AAMC). It has been documented that medical students do not believe that they have received adequate training for responding to disasters. The purpose of this pilot study was to determine the inclusion of disaster medicine in the required course work of medical students at AAMC schools in the United States, and to identify the content areas addressed. METHODS: An electronic on-line survey was developed based upon published core competencies for health care workers, and distributed via e-mail to the education liaison for each medical school in the United States that was accredited by the AAMC. The survey included questions regarding the inclusion of disaster medicine in the medical school curricula, the type of instruction, and the content of instruction. RESULTS: Of the 29 (25.2%) medical schools that completed the survey, 31% incorporated disaster medicine into their medical school curricula. Of those schools that included disaster medicine in their curricula, 20.7% offered disaster material as required course work, and 17.2% offered it as elective course work. Disaster medicine topics provided at the highest frequency included pandemic influenza/severe acute respiratory syndrome (SARS, 27.5%), and principles of triage (10.3%). The disaster health competency included most frequently was the ability to recognize a potential critical event and implement actions at eight (27.5%) of the responding schools. CONCLUSIONS: Only a small percentage of US medical schools currently include disaster medicine in their core curriculum, and even fewer medical schools have incorporated or adopted competency-based training within their disaster medicine lecture topics and curricula.

Applications of Artificial Intelligence and Machine Learning in Disasters and Public Health Emergencies.

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.

Developing Public Health Emergency Response Leaders in Incident Management: A Scoping Review of Educational Interventions.

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.

Disaster and public health emergency health data collection and management: A scoping review.

OBJECTIVE: The World Health Organization (WHO) developed the Emergency Medical Team (EMT) Minimum Data Set (MDS) to provide a structured, data-based approach to health data collection and management during disasters and public health emergencies. Given recent creation of the EMT MDS, we conducted a scoping review to gauge current practices surrounding health data collection and sharing in emergent settings. DESIGN: An English-based scoping review of PubMed and Embase databases of publications before June 28, 2021. MAIN OUTCOME MEASURES: The review aimed to identify facilitators and barriers to the implementation of the WHO-standardized health data collection systems in the context of disasters and public health emergencies; characterize best practices regarding implementation of an MDS to improve health data collection capacity in differing settings; and highlight internationally accepted, standardized tools or methods for setting up essential public health data for disaster response. RESULTS: A total of 8,038 citations from PubMed and Embase were imported into Covidence with 46 duplicates removed. Among these, 7,992 citations underwent title screening and abstract review, with 161 articles proceeding to full-text article review where an additional 109 articles were excluded. Fifty-two citations were included in final data abstraction. CONCLUSIONS: Findings revealed a range of critical operational, structural, and functional insights of relevance to implementation of the EMT MDS. The literature identified facilitators and barriers to collecting and storing disaster-based datasets, gaps in standardization of data collection resulting in poor data quality during the transition from the acute to post-acute phase, and best practices in the collection of EMT MDS.

Origin of novel coronavirus causing COVID-19: A computational biology study using artificial intelligence.

Origin of the COVID-19 virus (SARS-CoV-2) has been intensely debated in the scientific community since the first infected cases were detected in December 2019. The disease has caused a global pandemic, leading to deaths of thousands of people across the world and thus finding origin of this novel coronavirus is important in responding and controlling the pandemic. Recent research results suggest that bats or pangolins might be the hosts for SARS-CoV-2 based on comparative studies using its genomic sequences. This paper investigates the SARS-CoV-2 origin by using artificial intelligence (AI)-based unsupervised learning algorithms and raw genomic sequences of the virus. More than 300 genome sequences of COVID-19 infected cases collected from different countries are explored and analysed using unsupervised clustering methods. The results obtained from various AI-enabled experiments using clustering algorithms demonstrate that all examined SARS-CoV-2 genomes belong to a cluster that also contains bat and pangolin coronavirus genomes. This provides evidence strongly supporting scientific hypotheses that bats and pangolins are probable hosts for SARS-CoV-2. At the whole genome analysis level, our findings also indicate that bats are more likely the hosts for the COVID-19 virus than pangolins.

Characteristics of SARS-CoV-2 Seropositivity among Emergency Department Healthcare Workers at a Tertiary Care Center in Baltimore.

Early in the COVID-19 pandemic (March−July 2020 in Baltimore), emergency department (ED) healthcare workers (HCWs) were considered to be at greater risk of contracting SARS-CoV-2. Limited data existed, however, on the prevalence of SARS-CoV-2 infection and its impact in this workforce population. We enrolled 191 ED HCWs from a tertiary academic center, administered baseline and weekly surveys, and tested them twice (July and December 2020) for serum antibodies against SARS-CoV-2 spike protein. Approximately 6% (11 of 191, 5.8%) of ED HCWs had spike antibodies in July, a prevalence that doubled by December (21 of 174, 12.1%). A positive PCR test was self-reported by 15 of 21 (71%) seropositive and 6 of 153 (4%) seronegative HCWs (p < 0.001). Of the total 27 HCWs who had antibodies and/or were PCR positive, none required hospitalization, 18 (67%) had a self-perceived COVID-19 illness, and 12 of the 18 reported symptoms. The median number of missed workdays was 8.5 (ranging from 2 to 21). While most seropositive ED HCWs who reported symptoms took work absences, none required hospitalization, indicating that COVID-19's impact on staffing prior to vaccination was not as great as feared.

Providing Quality of Care in Fragile and Vulnerable Settings: Lessons from South Sudan.

BACKGROUND: In 2020, the World Health Organization (WHO) released a report concerning planning and actions to provide quality of care in fragile, conflict-affected, and vulnerable areas. South Sudan, the world's newest country, has encountered both natural and man-made disasters in recent years that have posed marked challenges to delivery of care. The Southern Sudan Healthcare Organization (SSHCO) operates as a non-governmental organization (NGO) in this setting, delivering and improving healthcare through war, flooding, and infectious outbreaks. OBJECTIVE: The goal of this paper is to highlight the challenges faced in providing care in South Sudan from an NGO perspective and apply the recent WHO guidelines on quality of care to optimize practical implementation. METHOD: Each of the WHO's eight elements for quality of care in South Sudan were examined in relation to the experience of SSHCO from 2013-2021. Analysis included: 1. summary of the WHO element; 2. examples of successful implementation; 3. barriers to implementation; and 4. recommendations to improve implementation. FINDINGS: The team found that communication and coordination were the most important aspects of improving quality of care in South Sudan. These should be prioritized and include intergovernmental partners, the local and national Ministry of Health (MOH), NGOs, and community stakeholders. Communication and coordination should foster community engagement, improved data collecting and reporting, and sharing of publicly accessible information. Better clinical staff training and governance are also required to ensure the most effective use of limited resources. CONCLUSION: South Sudan faces many barriers to quality of care with communication and coordination identified among the foremost issues. Practical application of the WHO elements of quality of care can assist NGOs in effectively identifying areas for improvement to deliver better quality essential health services.

State of public health emergency response leadership training: A multitiered organizational perspective.

OBJECTIVE: To capture organizational level information on the current state of public health emergency response leadership training. DESIGN: A web-based questionnaire. PARTICIPANTS: This multitiered assessment of health departments included two distinct respondent groups: (1) Public Health Emergency Preparedness (PHEP) Cooperative Agreement recipients (n = 34) and (2) local health departments (LHDs) (n = 169) representative of different agency sizes and populations served. RESULTS: Overall, PHEP and LHD respondents expressed a clear preference for participatory learning with practical drills/exercises and participatory workshops as the preferred training delivery modes. Compared with technical and role-specific training, leadership training was less available. For both PHEP and LHD respondents, staff availability for training is most notably limited due to lack of time. For PHEP respondents, a common factor limiting agency ability to offer training is lack of mentors/instructors, whereas for LHD respondents, it is limited funding. CONCLUSIONS: Efforts should focus on increasing accessibility and the continued development of rigorous and effective training based on practical experience in all aspects of multitiered public health emergency response leadership.

Characterizing hospital workers' willingness to report to duty in an influenza pandemic through threat- and efficacy-based assessment.

BACKGROUND: Hospital-based providers' willingness to report to work during an influenza pandemic is a critical yet under-studied phenomenon. Witte's Extended Parallel Process Model (EPPM) has been shown to be useful for understanding adaptive behavior of public health workers to an unknown risk, and thus offers a framework for examining scenario-specific willingness to respond among hospital staff. METHODS: We administered an anonymous online EPPM-based survey about attitudes/beliefs toward emergency response, to all 18,612 employees of the Johns Hopkins Hospital from January to March 2009. Surveys were completed by 3426 employees (18.4%), approximately one third of whom were health professionals. RESULTS: Demographic and professional distribution of respondents was similar to all hospital staff. Overall, more than one-in-four (28%) hospital workers indicated they were not willing to respond to an influenza pandemic scenario if asked but not required to do so. Only an additional 10% were willing if required. One-third (32%) of participants reported they would be unwilling to respond in the event of a more severe pandemic influenza scenario. These response rates were consistent across different departments, and were one-third lower among nurses as compared with physicians. Respondents who were hesitant to agree to work additional hours when required were 17 times less likely to respond during a pandemic if asked. Sixty percent of the workers perceived their peers as likely to report to work in such an emergency, and were ten times more likely than others to do so themselves. Hospital employees with a perception of high efficacy had 5.8 times higher declared rates of willingness to respond to an influenza pandemic. CONCLUSIONS: Significant gaps exist in hospital workers' willingness to respond, and the EPPM is a useful framework to assess these gaps. Several attitudinal indicators can help to identify hospital employees unlikely to respond. The findings point to certain hospital-based communication and training strategies to boost employees' response willingness, including promoting pre-event plans for home-based dependents; ensuring adequate supplies of personal protective equipment, vaccines and antiviral drugs for all hospital employees; and establishing a subjective norm of awareness and preparedness.
