The role of nurses in surveillance to enhance global health security: A delphi study.

BACKGROUND: Internationally, nurses are gaining recognition for their contributions to public health and global health initiatives, however, their contributions to surveillance and the detection of new and emerging infectious disease, which is an important element of global health security, remain largely unknown. PURPOSE: The purpose of this study was to investigate the perceptions of nurse experts related to the current and optimal roles of nurses in surveillance of new and emerging infectious diseases. Additionally, this study aimed to identify the skills needed by nurses in all practice settings for optimal performance of surveillance and to identify barriers to achieving optimal performance of surveillance. METHODS: A three-round Delphi study was conducted. Nurse experts participated in Round 1 interviews followed by ranking current and optimal role, skill, and barrier statements in Rounds 2 and 3. FINDINGS: Findings revealed four current roles and 13 optimal roles for nurses in surveillance, 13 skills needed to perform surveillance activities, and seven barriers to optimal performance of surveillance activities by nurses. DISUCSSION: Results of this study are intended to inform nursing practice and education in the U.S., and to provide guidance on the role of nurses in surveillance of new and emerging infectious disease as part of the Global Health Security Agenda.

Emergency nurses' perceptions regarding the risks appraisal of the threat of the emerging infectious disease situation in emergency departments.

Purpose: Emerging infectious diseases are considered as a pressing challenge to global public health. Throughout public health response to emerging infectious diseases, emergency nurses are situated at the forefront of the healthcare system. The present study has explored emergency nurses' perceptions regarding the risks appraisal of the threat of the emerging infectious disease situation in emergency department context.Methods: The present study used a qualitative descriptive approach. A purposive sampling method was employed to recruit emergency nurses who worked in public hospitals in Hong Kong. Semi-structured interviews were conducted to 24 emergency nurses. The data were interpreted using a thematic analysis strategy.Results: Five overarching themes emerged from the data: (1) the novelty of an emerging infectious disease, (2) the severity of an emerging infectious disease, (3) the proximity to an emerging infectious disease, (4) the complexity of an emerging infectious disease situation, and (5) the response levels towards an emerging infectious disease situation.Conclusion: It is anticipated that the information may help to predict the attitudes and behaviours of emergency nurses in future impending epidemic events, enhancing emergency nurses' preparedness towards in such situations.Abbreviations: EID: Emerging infectious disease; ED: Emergency department; SARS: Severe acute respiratory syndrome; MERS: Middle East respiratory syndrome; WHO: World Health Organization; RN: Registered nurse; APN: Advanced practice nurse; NO: Nursing officer.

Factors influencing nurses' intention to care for patients with emerging infectious diseases: Application of the theory of planned behavior.

Emerging infectious diseases have caused many health problems and have been identified as a major health issue worldwide. The aim of this descriptive, cross-sectional survey study was to investigate nursing intention among nurses caring for emerging infectious disease patients in Korea and to describe factors influencing nurses' intention to care by applying the theory of planned behavior. A total of 147 Korean nurses were included and data accrued using an online questionnaire. Among the independent variables, perceived behavioral control, attitudes toward the behavior, and sex significantly influenced nursing intention. These variables explained 55.1% of nursing intention to care for patients with emerging infectious diseases, and perceived behavioral control (confidence or self-efficacy in caring for patients) was the strongest predictor. These findings showed the usefulness of the theory of planned behavior in predicting nurses' intention to care for patients with emerging infectious diseases. Providing an educational program on caring for patients with pandemic diseases would also increase self-confidence and reduce concerns. In addition, institutional support, such as compensation payments and recognition from administrators, would also strengthen positive attitudes among nurses.

Measles: A clinician's guide to a reemerging disease.

Measles has re-emerged in the US for a variety of reasons, including misinformation spread by antivaccination advocates and imported cases from countries where infected children may be too young for immunization. Prompt diagnosis and isolation can help reduce measles transmission.

Emerging Infectious Diseases.

Emerging infectious diseases (EID) and reemerging infectious diseases are increasing globally. Zoonotic diseases are transmitted from animals to humans through direct contact or through food, water, and the environment. Vector-borne diseases are major sources of mortality and morbidity globally. Three mosquito-borne viruses are yellow fever, chikungunya virus, and dengue virus. Recent EIDs include Candida auris, Elizabethkingia anopheles, The Lone Star tick, and avian influenza H7N2. In addition, mcr-1 may contribute to the dissemination of drug resistance to gram-negative bacteria. Nurses play a major role in the identification and prevention of EID within health care settings.

Bridging the gap between guidelines and practice in the management of emerging infectious diseases: a qualitative study of emergency nurses.

AIMS AND OBJECTIVES: To explore the difficulties and strategies regarding guideline implementation among emergency nurses. BACKGROUND: Emerging infectious diseases remain an underlying source of global health concern. Guidelines for accident and emergency departments would require adjustments for infectious disease management. However, disparities between guidelines and nurses' practice are frequently reported, which undermines the implementation of these guidelines into practice. This article explores the experience of frontline emergency nurses regarding guideline implementation and provides an in-depth account of their strategies in bridging guideline-practice gaps. DESIGN: A qualitative descriptive design was used. METHODS: Semi-structured, face-to-face, individual interviews were conducted between November 2013-May 2014. A purposive sample of 12 frontline emergency nurses from five accident and emergency departments in Hong Kong were recruited. The audio-recorded interviews were transcribed verbatim and analysed with a qualitative content analysis approach. RESULTS: Four key categories associated with guideline-practice gaps emerged, including getting work done, adapting to accelerated infection control measures, compromising care standards and resolving competing clinical judgments across collaborating departments. The results illustrate that the guideline-practice gaps could be associated with inadequate provision of corresponding organisational supports after guidelines are established. CONCLUSIONS: The nurses' experiences have uncovered the difficulties in the implementation of guidelines in emergency care settings and the corresponding strategies used to address these problems. The nurses' experiences reflect their endeavour in adjusting accordingly and adapting themselves to their circumstances in the face of unfeasible guidelines. RELEVANCE TO CLINICAL PRACTICE: It is important to customise guidelines to the needs of frontline nurses. Maintaining cross-departmental consensus on guideline interpretation and operation is also indicated as an important component for effective guideline implementation.

Middle East Respiratory Syndrome Coronavirus.

Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is an emerging infectious disease that can present with flu-like symptoms. In individuals with comorbidities or who are immunosuppressed, it can be deadly. The disease is transmitted through contact with someone who has MERS-CoV. The occupational health nurse must be cognizant of and educate the workforce about MERS-CoV transmission, prevention, and treatment.

Necrotizing community-acquired methicillin-resistant Staphylococcus aureus pneumonia: an emerging problem in correctional facilities.

Community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) skin infections have been common in prisons for more than a decade. However, CA-MRSA as a cause of pneumonia has been reported infrequently. This infection can present with flu-like symptoms and rapidly progress, possibly leading to death in a matter of days. Two cases of MRSA community-acquired pneumonia (CAP) associated with influenza-like illness in correctional officers employed in two separate prisons within the California prison system are presented. Both individuals were previously healthy, but one died of this disease. MRSA is an uncommon, but now recognized, cause of CAP. These cases are notable for their unique presentation and occurrence in non-health care, occupational settings. Prompt diagnosis and intervention by occupational health nurses and physicians are critical to improving outcomes, especially in high-risk settings such as prisons. These worksites need an effective occupational health program to manage MRSA, with adequate training for both employees and inmates.

Doenças emergentes e condições de trabalho de enfermagem: um estudo de caso durante a pandemia de H1N1 no Rio de Janeiro / Emerging diseases and conditions of work of nursing: a case study during the H1N1 pandemic in Rio de Janeiro

As doenças infecto-parasitárias, ainda hoje, em pleno século XXI são responsáveis por uma quantidade generosa de morbidade e mortalidade no Brasil e no mundo. Muitas delas são amplamente influenciadas pelas mudanças climáticas que estão ocorrendo em todo o planeta fazendo com que sua incidência e distribuição geográfica aumentem. A dengue é considerada a principal doença reemergente nos países tropicais e subtropicais. A malária tem forte incidência nos países ao sul do deserto do Saara na África, ocorrendo também em vários países da América do Sul que possuem parte da região Amazônica em seu território. Várias doenças voltam a assolar a população de vários locais como as leishmanioses, a Doença de Lyme, erlichioses entre outras. Em março de 2009 começam a ocorrer os primeiros casos de uma nova doença inicialmente denominada Influenza suína, a qual, levou alguns indivíduos a óbito em Oaxaca, uma cidade mexicana localizada a 400 quilômetros da capital. Rapidamente, a doença se espalhou pelo país e posteriormente, no começo do mês de abril de 2009 já, existiam relatos de casos em vários países. O objetivo geral desta pesquisa é verificar em que medida o cuidado de enfermagem realizado expressou um maior ou menor grau de controle do enfermeiro sobre seu trabalho, apontando para os potenciais riscos (biológicos) de adoecimento e impactos negativos na saúde deste trabalhador. O presente estudo foi desenvolvido por meio de uma abordagem quantitativa com desenho longitudinal e observacional, delineamento de pesquisa não experimental e caráter descritivo. Foi feita a análise observacional nas tendas quanto a sua infraestrutura e posteriormente foi passado um questionário aos enfermeiros pautado em questões sobre o risco biológico que estes estavam sendo submetidos...

Infectious-parasitic diseases, up to the present, in XXI century are responsible for a high morbidity and mortality rate in Brazil as well as overseas. Many of them are widely influenced by climatic modifications that have been occuring all over the planet leading to an increase in their incidence and geographical distribution. Dengue is considered the main reemerging disease in tropical and subtropical countries. Malaria has strong incidence in countries that are in the south of Sahara desert in Africa, also occuring in many countries of South America that have part of their territory in Amazon region. A great deal of diseases have been frightening the population once again in many places, as leishmanioses, Lyme Disease, erlichioses, for instance. In March, 2009 the first cases of a new disease initially termed Influenza swine started to appear, leading some subjects to death in Oaxaca, a mexican city localized 400 kilometers far from the capital. Rapidly ,the disease had spread all over the country and later, in the beginning of April , 2009 there were some related cases in several countries. The overall aim of this study is to verify to what extent the nursing care that is carried out has expressed a higher or lower degree of control from the part of the nurse about his/her job, pointing at potential risks (biological) of illnesses and negative impacts into the worker health status. This study was developed by means of quantitative approach with longitudinal and observational design, a non experimental research and descriptive features. An observational analysis was carried out at the tents for their infra-structure and after this, a questionnaire was applied to the nurses based on matters as the biological risk they were being exposed...

Hospice utilization during the SARS outbreak in Taiwan.

BACKGROUND: The severe acute respiratory syndrome (SARS) epidemic threw the world into turmoil during the first half of 2003. Many subsequent papers have addressed its impact on health service utilization, but few have considered palliative (hospice) care. The aim of the present study was to describe changes in hospice inpatient utilization during and after the SARS epidemic in 2003 in Taiwan. METHODS: The data sources were the complete datasets of inpatient admissions during 2002 and 2003 from the National Health Insurance Research Database. Before-and-after comparisons of daily and monthly utilizations were made. Hospice analyses were limited to those wards that offered inpatient services throughout these two years. The comparisons were extended to total hospital bed utilization and to patients who were still admitted to hospice wards during the peak period of the SARS epidemic. RESULTS: Only 15 hospice wards operated throughout the whole of 2002 and 2003. In 2003, hospice utilization began to decrease in the middle of April, reached a minimum on 25 May, and gradually recovered to the level of the previous November. Hospices showed a more marked reduction in utilization than all hospital beds (e.g. -52.5% vs. -19.9% in May 2003) and a slower recovery with a three-month lag. In total, 566 patients were admitted to hospice wards in May/June 2003, in contrast to 818 in May/June 2002. Gender, age and diagnosis distributions did not differ. CONCLUSION: Hospice inpatient utilization in Taiwan was indeed more sensitive to the emerging epidemic than general inpatient utilization. A well-balanced network with seamless continuity of care should be ensured.

Early detection and surveillance for biopreparedness and emerging infectious diseases.

Biological weapons and emerging infectious diseases pose a significant risk to public health. A timely response is needed to effectively treat and contain a potential infectious disease outbreak. Detection and surveillance of biological agents needs to be sensitive and specific to allow providers to quickly and accurately identify the disease process and begin the necessary response procedures. This article addresses the importance of early detection and surveillance of both intentional and unintentional biological events. Challenges of bioterrorism and the nursing role in response are discussed. Epidemiological considerations, such as route of transmission and personal protective equipment, are presented. An overview of the major surveillance systems, including advances in computer-based technology, is provided to help health care providers become aware of current surveillance systems and clinical decision support tools designed to help diminish the impact of biological threats.

SARS: caring for patients in Hong Kong.

AIM AND OBJECTIVE: To explore in depth the experiences of nurses' caring for SARS patients in Hong Kong. BACKGROUND: Severe Acute Respiratory Syndrome (SARS) dramatically demonstrates the global havoc that can be wreaked by a newly emerging infectious disease. The current literature either has a predominantly biomedical focus or deals with the psychological impact on healthcare workers. Published studies on the lived experience of nurses caring for SARS patients are currently lacking. DESIGN: A phenomenological design. METHODS: Using methods consistent with Husserl's philosophy, eight Registered Nurses working in three regional hospitals in Hong Kong were invited to participate in sharing their lived experience of caring for SARS patients and data were analysed using Colaizzi's approach. RESULTS: The three major themes explicated were: the various emotions experienced in caring for SARS patients, the concept of uncertainty and revisiting the 'taken for granted' features of nursing. CONCLUSION: These themes, when taken together, describe the essence of the voyage undertaken by nurses who cared for SARS patients during the outbreak. The findings of this study indicate that extensive and ongoing support is needed to prepare and enable nurses to care for SARS patients during a crisis and make it easier for nurses to deal with the various uncertainties. RELEVANCE TO CLINICAL PRACTICE: The essence of caring for SARS patients is highlighted in this study. The experience of caring for SARS patients prompts nurses to find meaning in their experience(s), and to develop knowledge and attitudes on how best to care for patients and prepare for a new crisis in the future. This paper considers a more in-depth understanding of the lived experience of nurses during the crisis and the relevance of this perspective for education and support of nurses.

Nurses and the control of infectious disease. Understanding epidemiology and disease transmission is vital to nursing care.

Epidemiology examines the distribution and source of a disease in a population. Understanding epidemiology and disease transmission is vital to nursing care. Infectious disease transmission requires three components: an agent (virus, bacterium, parasite or other microbe), a vulnerable host and a conducive environment. Disease spread can occur through direct contact or via indirect methods (airborne droplets, vectors, fomites, water or food). Intervention can occur by attacking the agent (e.g., using microbicides), changing the environment (e.g., providing negative pressure rooms) or strengthening the host (e.g., vaccination). Three epidemiologically relevant microbes are the SARS (severe acute respiratory syndrome)-associated coronavirus, methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile (C. difficile). The first is an emerging pathogen, and the latter two are existing agents that have mutated such that they are resistant to their standard treatments. For SARS, control measures include screening for possible cases and appropriate triage, respiratory and barrier precautions within the healthcare facility, and voluntary isolation in the community for contacts or healthcare workers who exhibit symptoms. Control measures for MRSA include the screening of patient lesions, isolating or cohorting patients who are already infected, covering wounds with impermeable dressings, treating staff and patient carriers with antibiotics, and improved hygiene. Control measures for C. difficile Control measures include paying close attention to the hygiene of the clinical setting, disinfecting using bleach and the isolation of infected patients.

Nursing care of patients with severe acute respiratory syndrome in the intensive care unit: case reports in Hong Kong.

Severe acute respiratory syndrome (SARS) was diagnosed in more than 8437 patients in 25 countries between February and July 2003. During this period the World Health Organisation issued a global alert about SARS and together with the Centre for Disease Control have coordinated their efforts to investigate its pathogenesis and treatment. The outbreak in Hong Kong has been dramatic due to its geographical proximity with Guangdong province, China where the first case of SARS was reported. SARS has been described as a rapidly progressive, sometimes fatal pneumonia with a case fatality rate of 7.6% requiring intensive care. The four case reports illustrate a number of important points concerning the recognition, treatment, management and prevention of SARS, and highlights the importance of considering vigilant assessment and monitoring of patients with SARS. The purpose of this paper is to share our experiences in caring for critically ill patients with SARS in the intensive care unit to nurses globally in order to reduce SARS' morbidity and mortality as well as to protect nurses and other healthcare workers from this disease that is so far threatening the community at large.
