Project description:OBJECTIVES:The purpose of this study was to define and delineate specific non-technical competencies for first-line public health responders in Chemical, Biological, Radiological, and Nuclear (CBRN) emergencies in China. STUDY DESIGN:A qualitative study was conducted in China involving interviews with key informants in the field of health response to CBRN disasters. METHODS:One-on-one in-depth interviews were carried out with 20 participants, including expert members of National Medical Response Teams for CBRN disasters, officials at emergency management authorities, and scholars of academic institutions related to CBRN emergency. Interviews were recorded using audio equipment, transcribed, and coded into codable passages as per grounded theory using NVivo software. Themes were identified within the transcriptions by using thematic analysis. RESULTS:A total of 159 codable passages were produced. Eight domains of non-technical core competencies were identified: (1) situation awareness, (2) communication skills, (3) collaboration, (4) resource management, (5) task management, (6) cultural competency, (7) austere environment skills, and (8) physical stamina. CONCLUSIONS:The study identified a variety of competencies for on-scene public health responders in CBRN emergencies. The findings of this study could specifically benefit development of strategy and improvement of content of education and training. Further research that involves input from the disaster response community at large is needed for the validation of these competencies.

Project description:Background The global COVID-19 pandemic has posed a major threat to human life and health, and new media technologies have intensified the spread of risk perception. Purpose This study aimed to explore the impact of risk information ground on online users’ perceived health risks, and further explore the mediating role of psychological distance and the moderating role of self-efficacy. Methods A total of 25 Internet users from different provinces in China were interviewed in-depth, NVIVO.11 was used to qualitatively analyze the interview text data and construct a theoretical model. A total of 492 interviewees were recruited in order to complete a scenario questionnaire, SPSS-27 was used to perform orthogonal experiments, generate eight combinatorial scenarios, analyze demographic data, and clean and prepare data for testing hypotheses. SmartPLS 3.0 was used to test the conceptual model using the structural equation model (SEM) of the partial least squares (PLS). Results The analysis of the SEM model shows that all planned hypotheses (Information fluency → Information diagnosability, Information extensibility → Information diagnosability, Information diagnosability → Psychological distance, Platform interactivity → Scenario embeddedness, Network connectivity → Scenario embeddedness, Scenario embeddedness → Psychological distance, Psychological distance → Risk perception, Psychological distance → Self-efficacy → Risk perception, Information fluency → Information diagnosability → Psychological distance → Risk perception, Information extensibility → Information diagnosability → Psychological distance → Risk perception, Platform interactivity → Scenario embeddedness → Psychological distance → Risk perception, Network connectivity → Scenario embeddedness → Psychological distance → Risk perception) are confirmed. Conclusion This study found that the information ground factors significantly affect online users’ perceptions of health risks, psychological distance mediates the effect of information ground factors on risk perception, and self-efficacy negatively moderates the effect of psychological distance on risk perception.

Project description:Adherence to public health recommendations is critical for public safety and well-being. Effective and appropriate communication plays an important role in whether populations trust government and public health authorities, and the extent to which people follow public health recommendations. Poor trust in communication from public health authorities can pose significant challenges for mitigating public health emergencies and maintaining health security. This study aimed to explore the importance of trust in and understanding of communication from public health authorities in improving adherence to public health recommendations, and how that communication can be improved to develop and maintain public trust, particularly in the context of public health emergencies. To understand which factors are important for public trust in communication from public health authorities, we conducted in-depth interviews (n?=?25) with a racially and demographically diverse group of individuals living in Baltimore. We found that communication source and communication transparency, such as timeliness, completeness, and clarity of information, were critical constructs of trust in communication from public health authorities. We also found that many participants misunderstood the flow of information from public health authorities to news media, and many were unaware that public health authorities provide the most reliable source of health information and recommendations during a public health emergency. To ensure adherence to public health recommendations, the public needs to trust that public health authorities are providing accurate, practical, and prudent recommendations. Drawing on these results, we provide several recommendations for developing and optimizing communication from various public health authorities.

Project description:ObjectivesThe COVID-19 pandemic threatens to widen existing gender inequities worldwide. A growing body of literature assesses the harmful consequences of public health emergencies (PHEs) for women and girls; however, evidence of what works to alleviate such impacts is limited. To inform viable mitigation strategies, we reviewed the evidence on gender-based interventions implemented in PHEs, including disease outbreaks and natural disasters.MethodsWe conducted a rapid scoping review to identify eligible studies by systematically searching the databases MEDLINE, Global Health and Web of Science with the latest search update on 28 May 2021. We used the Sustainable Development Goals as a guiding framework to identify eligible outcomes of gender (in)equality.ResultsOut of 13 920 records, 16 studies met our eligibility criteria. These included experimental (3), cohort (2), case-control (3) and cross-sectional (9) studies conducted in the context of natural disasters (earthquakes, droughts and storms) or epidemics (Zika, Ebola and COVID-19). Six studies were implemented in Asia, seven in North/Central America and three in Africa. Interventions included economic empowerment programmes (5); health promotion, largely focused on reproductive health (10); and a postearthquake resettlement programme (1). Included studies assessed gender-based outcomes in the domains of sexual and reproductive health, equal opportunities, access to economic resources, violence and health. There was a dearth of evidence for other outcome domains relevant to gender equity such as harmful practices, sanitation and hygiene practices, workplace discrimination and unpaid work. Economic empowerment interventions showed promise in promoting women's and girls' economic and educational opportunities as well as their sexual and reproductive health during PHEs. However, some programme beneficiaries may be at risk of experiencing unintended harms such as an increase in domestic violence. Focused reproductive health promotion may also be an effective strategy for supporting women's sexual and reproductive health, although additional experimental evidence is needed.ConclusionsThis study identified critical evidence gaps to guide future research on approaches to alleviating gender inequities during PHEs. We further highlight that interventions to promote gender equity in PHEs should take into account possible harmful side effects such as increased gender-based violence.Review registrationDOI 10.17605/OSF.IO/8HKFD.

Project description:Humanitarian emergencies, including complex emergencies associated with fragile states or areas of conflict, affect millions of persons worldwide. Such emergencies threaten global health security and have complicated but predictable effects on public health. The Centers for Disease Control and Prevention (CDC) Emergency Response and Recovery Branch (ERRB) (Division of Global Health Protection, Center for Global Health) contributes to public health emergency responses by providing epidemiologic support for humanitarian health interventions. To capture the extent of this emergency response work for the past decade, we conducted a retrospective review of ERRB's responses during 2007-2016. Responses were conducted across the world and in collaboration with national and international partners. Lessons from this work include the need to develop epidemiologic tools for use in resource-limited contexts, build local capacity for response and health systems recovery, and adapt responses to changing public health threats in fragile states. Through ERRB's multisector expertise and ability to respond quickly, CDC guides humanitarian response to protect emergency-affected populations.

Project description:ObjectiveTo develop a virtual reality simulation training programme, and further verify the effect of the programme on improving the response capacity of emergency reserve nurses confronting public health emergencies.DesignA prospective quasiexperimental design with a control group.ParticipantsA total of 120 nurses were recruited and randomly divided into the control group and the intervention group.InterventionParticipants underwent a 3-month training. The control group received the conventional training of emergency response (eg, theoretical lectures, technical skills and psychological training), while the intervention group underwent the virtual reality simulation training in combination with skills training. The COVID-19 cases were incorporated into the intervention group training, and the psychological training was identical to both groups. At the end of the training, each group conducted emergency drills twice. Before and after the intervention, the two groups were assessed for the knowledge and technical skills regarding responses to fulminate respiratory infectious diseases, as well as the capacity of emergency care. Furthermore, their pandemic preparedness was assessed with a disaster preparedness questionnaire.ResultsAfter the intervention, the scores of the relevant knowledge, the capacity of emergency care and disaster preparedness in the intervention group significantly increased (p<0.01). The score of technical skills in the control group increased more significantly than that of the intervention group (p<0.01). No significant difference was identified in the scores of postdisaster management in two groups (p>0.05).ConclusionThe virtual reality simulation training in combination with technical skills training can improve the response capacity of emergency reserve nurses as compared with the conventional training. The findings of the study provide some evidence for the emergency training of reserve nurses in better response to public health emergencies and suggest this methodology is worthy of further research and popularisation.

Project description:During the last decade, conflict or natural disasters have displaced unprecedented numbers of persons. This leads to conditions prone to outbreaks that imperil the health of displaced persons and threaten global health security. Past literature has minimally examined the association of communicable disease outbreaks with complex emergencies (CEs) and natural disasters (NDs).To examine this association, we identified CEs and NDs using publicly available datasets from the Center for Research on the Epidemiology of Disasters and United Nations Flash and Consolidated Appeals archive for 2005-2014. We identified outbreaks from World Health Organization archives. We compared findings to identify overlap of outbreaks, including their types (whether or not of a vaccine-preventable disease), and emergency event types (CE, ND, or Both) by country and year using descriptive statistics and measure of association.There were 167 CEs, 912 NDs, 118 events linked to 'Both' types of emergencies, and 384 outbreaks. Of CEs, 43% were associated with an outbreak; 24% NDs were associated with an outbreak; and 36% of 'Both' types of emergencies were associated with an outbreak. Africa was disproportionately affected, where 67% of total CEs, 67% of 'Both' events (CE and ND), and 46% of all outbreaks occurred for the study period. The odds ratio of a vaccine-preventable outbreak occurring in a CE versus an ND was 4.14 (95% confidence limits 1.9, 9.4).CEs had greater odds of being associated with outbreaks compared with NDs. Moreover, CEs had high odds of a vaccine-preventable disease causing that outbreak. Focusing on better vaccine coverage could reduce CE-associated morbidity and mortality by preventing outbreaks from spreading.

Project description:Objectives: During public health emergencies, people often scramble to buy scarce goods, which may lead to panic behavior and cause serious negative impacts on public health management. Due to the absence of relevant research, the internal logic of this phenomenon is not clear. This study explored whether and why public health emergencies such as the COVID-19 pandemic stimulate consumers' preference for scarce products. Methods: Applying the questionnaire survey method, two online surveys were conducted on the Credamo data platform in China. The first survey was launched in February and collected psychological and behavioral data from 1,548 participants. Considering the likelihood of population relocation due to the pandemic, a follow-up survey was conducted in August with 463 participants who had participated in the first survey and had not relocated to other cities between February and August. The hypotheses were tested with these data through stepwise regression analysis, bootstrapping, and robustness testing. Results: Pandemic severity was found to positively affect scarce consumption behavior and the effect was found to be situational; this indicates that the impact of the pandemic on scarce consumption was only significant during the pandemic. Further, it was found that materialism plays a mediating role in the relationship between pandemic severity and scarce consumption. Finally, the need to belong was found to play a moderating role between pandemic severity and materialism. Conclusion: This study findings imply that the scarce consumption behavior during public health emergencies can be reduced by decreasing materialism and increasing the need to belong. These findings may aid government leaders in managing public health emergencies.

Project description:The paradigm for the use of investigational drugs in public health emergencies has been recently tested to prevent and treat highly infectious and lethal diseases. Examples include the successful implementation of vaccine and therapeutic clinical trials during the recent Ebola outbreak in West Africa. On the other end of the spectrum was the Emergency Use Authorization (EUA) of peramivir in the treatment of H1N1 influenza virus that did not provide an opportunity to collect data or understand the effectiveness of the EUA program. Between the gold standard of a randomized controlled clinical trial and the problems associated with EUAs are the domain of expanded access protocols that may provide an avenue to make products available while awaiting licensure. This paper will examine the regulatory pathways in the United States (US) for the use of investigational drugs in a public health emergency as well as considerations when making these products available outside the US. Descriptions of the applications of the various approaches will be presented. Regardless of the pathway chosen, public health and clinical research planners need to work together to consider several factors associated with the respective options and maintain a goal of working toward the collection of data to support licensure before faced with future outbreaks. Finally, this paper will consider the lessons learned from public health response in the context of investigational drugs in other diseases where "right to try laws" may pose opportunities, as well as challenges.

Project description:Recent outbreaks of Ebola virus disease (2013-2016) and Zika virus (2015-2016) bring renewed recognition of the need to understand social pathways of disease transmission and barriers to care. Social scientists, anthropologists in particular, have been recognised as important players in disease outbreak response because of their ability to assess social, economic and political factors in local contexts. However, in emergency public health response, as with any interdisciplinary setting, different professions may disagree over methods, ethics and the nature of evidence itself. A disease outbreak is no place to begin to negotiate disciplinary differences. Given increasing demand for anthropologists to work alongside epidemiologists, clinicians and public health professionals in health crises, this paper gives a basic introduction to anthropological methods and seeks to bridge the gap in disciplinary expectations within emergencies. It asks: 'What can anthropologists do in a public health crisis and how do they do it?' It argues for an interdisciplinary conception of emergency and the recognition that social, psychological and institutional factors influence all aspects of care.
