White Paper on Early Critical Care Services in Low Resource Settings.

This White Paper has been formally accepted for support by the International Federation for Emergency Medicine (IFEM) and by the World Federation of Intensive and Critical Care (WFICC), put forth by a multi-specialty group of intensivists and emergency medicine providers from low- and low-middle-income countries (LMICs) and high-income countries (HiCs) with the aim of 1) defining the current state of caring for the critically ill in low-resource settings (LRS) within LMICs and 2) highlighting policy options and recommendations for improving the system-level delivery of early critical care services in LRS. LMICs have a high burden of critical illness and worse patient outcomes than HICs, hence, the focus of this White Paper is on the care of critically ill patients in the early stages of presentation in LMIC settings. In such settings, the provision of early critical care is challenged by a fragmented health system, costs, a health care workforce with limited training, and competing healthcare priorities. Early critical care services are defined as the early interventions that support vital organ function during the initial care provided to the critically ill patient-these interventions can be performed at any point of patient contact and can be delivered across diverse settings in the healthcare system and do not necessitate specialty personnel. Currently, a single "best" care delivery model likely does not exist in LMICs given the heterogeneity in local context; therefore, objective comparisons of quality, efficiency, and cost-effectiveness between varying models are difficult to establish. While limited, there is data to suggest that caring for the critically ill may be cost effective in LMICs, contrary to a widely held belief. Drawing from locally available resources and context, strengthening early critical care services in LRS will require a multi-faceted approach, including three core pillars: education, research, and policy. Education initiatives for physicians, nurses, and allied health staff that focus on protocolized emergency response training can bridge the workforce gap in the short-term; however, each country's current human resources must be evaluated to decide on the duration of training, who should be trained, and using what curriculum. Understanding the burden of critical Illness, best practices for resuscitation, and appropriate quality metrics for different early critical care services implementation models in LMICs are reliant upon strengthening the regional research capacity, therefore, standard documentation systems should be implemented to allow for registry use and quality improvement. Policy efforts at a local, national and international level to strengthen early critical care services should focus on funding the building blocks of early critical care services systems and promoting the right to access early critical care regardless of the patient's geographic or financial barriers. Additionally, national and local policies describing ethical dilemmas involving the withdrawal of life-sustaining care should be developed with broad stakeholder representation based on local cultural beliefs as well as the optimization of limited resources.

Towards developing a consensus assessment framework for global emergency medicine fellowships.

BACKGROUND: The number of Global Emergency Medicine (GEM) Fellowship training programs are increasing worldwide. Despite the increasing number of GEM fellowships, there is not an agreed upon approach for assessment of GEM trainees. MAIN BODY: In order to study the lack of standardized assessment in GEM fellowship training, a working group was established between the International EM Fellowship Consortium (IEMFC) and the International Federation for Emergency Medicine (IFEM). A needs assessment survey of IEMFC members and a review were undertaken to identify assessment tools currently in use by GEM fellowship programs; what relevant frameworks exist; and common elements used by programs with a wide diversity of emphases. A consensus framework was developed through iterative working group discussions. Thirty-two of 40 GEM fellowships responded (80% response). There is variability in the use and format of formal assessment between programs. Thirty programs reported training GEM fellows in the last 3 years (94%). Eighteen (56%) reported only informal assessments of trainees. Twenty-seven (84%) reported regular meetings for assessment of trainees. Eleven (34%) reported use of a structured assessment of any sort for GEM fellows and, of these, only 2 (18%) used validated instruments modified from general EM residency assessment tools. Only 3 (27%) programs reported incorporation of formal written feedback from partners in other countries. Using these results along with a review of the available assessment tools in GEM the working group developed a set of principles to guide GEM fellowship assessments along with a sample assessment for use by GEM fellowship programs seeking to create their own customized assessments. CONCLUSION: There are currently no widely used assessment frameworks for GEM fellowship training. The working group made recommendations for developing standardized assessments aligned with competencies defined by the programs, that characterize goals and objectives of training, and document progress of trainees towards achieving those goals. Frameworks used should include perspectives of multiple stakeholders including partners in other countries where trainees conduct field work. Future work may evaluate the usability, validity and reliability of assessment frameworks in GEM fellowship training.

Operationalising emergency care delivery in sub-Saharan Africa: consensus-based recommendations for healthcare facilities.

A major barrier to successful integration of acute care into health systems is the lack of consensus on the essential components of emergency care within resource-limited environments. The 2013 African Federation of Emergency Medicine Consensus Conference was convened to address the growing need for practical solutions to further implementation of emergency care in sub-Saharan Africa. Over 40 participants from 15 countries participated in the working group that focused on emergency care delivery at health facilities. Using the well-established approach developed in the WHO's Monitoring Emergency Obstetric Care, the workgroup identified the essential services delivered-signal functions-associated with each emergency care sentinel condition. Levels of emergency care were assigned based on the expected capacity of the facility to perform signal functions, and the necessary human, equipment and infrastructure resources identified. These consensus-based recommendations provide the foundation for objective facility capacity assessment in developing emergency health systems that can bolster strategic planning as well as facilitate monitoring and evaluation of service delivery.

Applying the lessons of maternal mortality reduction to global emergency health.

Over the last few decades, maternal health has been a major focus of the international community and this has resulted in a substantial decrease in maternal mortality globally. Although, compared with maternal illness, medical and surgical emergencies account for far more morbidity and mortality, there has been less focus on global efforts to improve comprehensive emergency systems. The thoughtful and specific application of the concepts used in the effort to decrease maternal mortality could lead to major improvements in global emergency health services. The so-called three-delay model that was developed for maternal mortality can be adapted to emergency service delivery. Adaptation of evaluation frameworks to include emergency sentinel conditions could allow effective monitoring of emergency facilities and further policy development. Future global emergency health efforts may benefit from incorporating strategies for the planning and evaluation of high-impact interventions.

Au cours des dernières décennies, la santé maternelle a figuré en bonne place dans les priorités de la communauté internationale et cela s'est traduit par une baisse considérable de la mortalité maternelle au niveau mondial. Or, même si la morbidité et la mortalité liées aux urgences médicales et chirurgicales sont bien plus élevées comparativement à celles associées aux pathologies maternelles, les efforts menés au niveau mondial pour améliorer les systèmes de soins d'urgence dans leur intégralité attirent beaucoup moins d'attention. Une application réfléchie et spécifique des concepts employés dans l'effort de réduction de la mortalité maternelle pourrait entraîner des améliorations notables au sein des services de santé d'urgence au niveau mondial. Le modèle dit « des trois retards ¼, conçu pour la mortalité maternelle, peut être transposé à la prestation des soins d'urgence. L'adaptation des cadres d'évaluation pour y inclure des critères-sentinelles évocateurs des cas d'urgence vitale pourraient permettre une surveillance efficace des centres d'urgences et la conception de politiques complémentaires. Les futurs efforts consacrés aux systèmes de soins d'urgence au niveau mondial pourraient également bénéficier de l'intégration de stratégies pour la planification et l'évaluation d'interventions à fort impact.

A lo largo de las últimas décadas, la salud materna ha sido un foco importante de la comunidad internacional y esto ha llevado a una disminución considerable de la mortalidad materna a nivel mundial. Aunque, en comparación con las enfermedades de la madre, las emergencias médicas y quirúrgicas son una causa mucho más importante de morbilidad y mortalidad, se ha puesto menos atención en los esfuerzos mundiales para mejorar los sistemas integrales de emergencia. La aplicación profunda y específica de los conceptos utilizados en el intento de disminuir la mortalidad materna puede llevar a mejoras importantes de los servicios sanitarios de emergencia mundiales. El denominado modelo de tres retrasos que se desarrolló para la mortalidad materna se puede adaptar a la prestación de servicios de emergencia. La adaptación de los marcos de evaluación para incluir condiciones centinela de emergencia podría permitir una supervisión efectiva de las instalaciones de emergencia y la elaboración de políticas adicionales. Los esfuerzos futuros en la sanidad de emergencia mundial podrían beneficiarse de la incorporación de estrategias para la planificación y evaluación de intervenciones de gran impacto.

Development of a humanized C1q A chain knock-in mouse: assessment of antibody independent beta-amyloid induced complement activation.

Evidence has been accumulating for a role of inflammation in the development of Alzheimer's disease (AD), a progressive neurodegenerative disorder causing a common form of dementia in the elderly. C1q, part of the initiation component of the classical complement pathway (CCP), is associated with beta-sheet, fibrillar amyloid plaques in AD brain. In vitro, beta-amyloid peptide in fibrillar beta-sheet conformation (fAbeta) can activate CCP via interaction of specific negatively charged amino acids of the beta-amyloid fibril with human C1q. Previous results using peptide inhibitors led to the hypothesis that a highly positively charged domain consisting of three arginine residues, such as that present in the N-terminal collagen-like region of the human C1q A chain, may be critical for the activation event. However, mouse C1q A chain lacks two of the three arginines in the corresponding C1q A chain collagen-like region. To test the hypothesis that this divergent activation domain results in a weaker C' activation and thus may contribute to the lower neuronal loss observed in transgenic mouse models of AD, a partially humanized C1q A chain knock-in mouse was generated. The mouse C1q A chain gene was modified by homologous recombination to replace 4 residues in the 13-20 amino acid region to mimic the corresponding sequence from human A chain. No significant differences in the expression of C1q were found in sera from mice homozygous for the humanized C1q A chain compared to littermate wild type mice. Two distinct C1 activation assays demonstrated that activation by fAbeta was not significantly different in the homozygous humanized C1q A chain mice. Activation of C1 by DNA, previously hypothesized to interact with this C1q A chain arginine-rich sequence was also not significantly different in the knock-in mouse. Molecular modeling based on the published crystal structure of human C1q B chain globular head and a beta-sheet model for fibrillar amyloid suggests an alternative arginine ladder in the globular head domain may provide the functional C1 activating interaction domains. The humanized C1q mouse generated here should provide a better animal model for assessing the mechanisms of C1 activation and the contribution of C1q to human health and disease.
