Disseminating information on acute public health events globally: experiences from the WHO's Disease Outbreak News.

WHO works, on a daily basis, with countries globally to detect, prepare for and respond to acute public health events. A vital component of a health response is the dissemination of accurate, reliable and authoritative information. The Disease Outbreak News (DON) reports are a key mechanism through which WHO communicates on acute public health events to the public. The decision to produce a DON report is taken on a case-by-case basis after evaluating key criteria, and the subsequent process of producing a DON report is highly standardised to ensure the robustness of information. DON reports have been published since 1996, and up to 2022 over 3000 reports have been published. Between 2018 and 2022, the most frequently published DON reports relate to Ebola virus disease, Middle East respiratory syndrome, yellow fever, polio and cholera. The DON web page is highly visited with a readership of over 2.6 million visits per year, on average. The DON report structure has evolved over time, from a single paragraph in 1996 to a detailed report with seven sections currently. WHO regularly reviews the DON report process and structure for improvements. In the last 25 years, DON reports have played a unique role in rapidly disseminating information on acute public health events to health actors and the public globally. They have become a key information source for the global public health response to the benefit of individuals and communities.

The safety and applicability of synthetic pyrethroid insecticides for aircraft disinsection: A systematic review.

BACKGROUND: Air travel contributes to the global spread of vectors and vector-borne infections. Although WHO provides guidance on methods for disinsection of aircraft, there is currently no harmonized or standardized decision-making process to decide when disinsection of an aircraft should be conducted. It is however compulsory for flights arriving in certain countries. Concerns have been expressed about the usefulness of disinsection for preventing the international spread of vectors and vector-borne diseases via air travel and possible toxicity for passengers and flight crew. METHODS: We performed a systematic literature review using the databases PubMed, Embase, Medline, Scopus and CINAHL to evaluate all research findings about the applicability and safety of chemical-based, aircraft disinsection. Official reports from the WHO were also screened. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and meta-analysis (PRISMA) statement. The literature search strategy included "disinsection, airplane/plane/aviation/aircraft" and several other search items including d-phenothrin, permethrin, insecticide. Papers in English, French and German were reviewed. Reports of adverse events attributed to the disinsection of aircraft were also searched. AMP and PS screened all papers of relevance and agreed on a final selection. RESULTS: Our search resulted in 440 papers of possible relevance. After screening, we included a total of 25 papers in this systematic review. Ten papers reported possible human toxicity and 17 papers addressed the applicability of disinsection and 2 papers addressed both topics. Chemical disinsection at recommended insecticide concentrations was found to be highly effective against a broad range of arthropods. Three papers reported passenger or crew illness possibly associated with insecticide spraying in passenger cabins - one describing a single passenger, the other two papers describing occupational illness of 12 and 33 aircrew members respectively, possibly due to aircraft disinsection. Another paper evaluating exposure of flight attendants to permethrin found higher levels of urinary metabolites in those working in planes that had recently been sprayed but this could not be linked to adverse health outcomes. CONCLUSION: Our analysis confirmed that disease vectors are carried on international flights and can pose a threat particularly to island populations and certain airport hub areas. Disinsection with permethrin or d-phenothrin was shown to be highly effective against vectors. Despite several hundred million passenger and crew exposures to chemical disinsection, very few proven cases of toxicity have been reported. There is limited evidence linking exposure to insecticide spraying with negative health impact.

Early implementation of WHO recommendations for the retention of health workers in remote and rural areas.

The maldistribution of health workers between urban and rural areas is a policy concern in virtually all countries. It prevents equitable access to health services, can contribute to increased health-care costs and underutilization of health professional skills in urban areas, and is a barrier to universal health coverage. To address this long-standing concern, the World Health Organization (WHO) has issued global recommendations to improve the rural recruitment and retention of the health workforce. This paper presents experiences with local and regional adaptation and adoption of WHO recommendations. It highlights challenges and lessons learnt in implementation in two countries - the Lao People's Democratic Republic and South Africa - and provides a broader perspective in two regions - Asia and Europe. At country level, the use of the recommendations facilitated a more structured and focused policy dialogue, which resulted in the development and adoption of more relevant and evidence-based policies. At regional level, the recommendations sparked a more sustained effort for cross-country policy assessment and joint learning. There is a need for impact assessment and evaluation that focus on the links between the rural availability of health workers and universal health coverage. The effects of any health-financing reforms on incentive structures for health workers will also have to be assessed if the central role of more equitably distributed health workers in achieving universal health coverage is to be supported.

La mauvaise répartition des travailleurs de la santé entre les zones urbaines et rurales demeure une préoccupation politique dans pratiquement tous les pays. Elle empêche l'accès équitable aux services de santé, elle peut contribuer à une augmentation du coût des soins de santé et de sous-utilisation des compétences des professionnels de la santé dans les zones urbaines, et elle représente un obstacle à la mise en place d'une couverture maladie universelle. Pour répondre à cette préoccupation qui existe depuis longtemps, l'Organisation mondiale de la Santé (OMS) a émis des recommandations visant à améliorer le recrutement et la rétention des travailleurs du secteur de la santé en milieu rural. Ce document présente différentes expériences locales et régionales concernant l'adaptation et l'adoption des recommandations de l'OMS. Il souligne les défis et les leçons tirées de mises en œuvre dans deux pays - en République démocratique populaire lao et en Afrique du Sud - et il offre une perspective plus vaste dans deux régions - en Asie et en Europe. Au niveau des pays, l'application des recommandations a permis un dialogue plus structuré et plus ciblé sur les règlementations, qui a abouti à l'élaboration et à l'adoption de politiques plus pertinentes basées sur les faits. Au niveau régional, les recommandations ont suscité un effort plus soutenu en ce qui concerne l'évaluation des politiques entre les pays et leur apprentissage commun. Il faut évaluer l'impact des liens qui existent entre la disponibilité des travailleurs de la santé dans les zones rurales et la couverture maladie universelle. Les effets de toutes les réformes financières sur les structures d'incitation des travailleurs de la santé devront également être évalués si le but principal est de répartir plus équitablement les travailleurs de la santé et d'atteindre une couverture maladie universelle.

La distribución ineficaz del personal sanitario entre las zonas urbanas y rurales constituye una preocupación política en casi todos los países, pues impide el acceso equitativo a los servicios sanitarios, puede contribuir al aumento de los costes de atención sanitaria y la infrautilización de las capacidades profesionales sanitarias en las zonas urbanas, y obstaculiza la cobertura sanitaria universal. Para solucionar este problema de larga data, la Organización Mundial de la Salud (OMS) ha publicado una serie de recomendaciones generales para mejorar la contratación a nivel rural y la conservación del personal sanitario. Este informe presenta las experiencias en relación con la adaptación local y regional, y la adopción de las recomendaciones de la OMS. Además, subraya los desafíos y las lecciones aprendidas de la aplicación en dos países, la República Democrática Popular Lao y Sudáfrica, y proporciona una perspectiva más amplia en dos regiones, en concreto, Asia y Europa. A nivel nacional, el uso de las recomendaciones facilitó un diálogo político más organizado y específico, lo que permitió el desarrollo y la adopción de políticas más relevantes con base empírica. A nivel regional, las recomendaciones motivaron un esfuerzo más firme para evaluar las políticas entre los países y el aprendizaje conjunto. Es necesario realizar una evaluación y una valoración del impacto que se centren en la relación entre la disponibilidad de personal sanitario en zonas rurales y la cobertura sanitaria universal. Asimismo, deben evaluarse los efectos de las reformas financieras en asistencia sanitaria sobre las estructuras de incentivos para el personal sanitario con miras a promover el papel central del mismo, distribuido de forma más equitativa, en la consecución de la cobertura sanitaria universal.

Addressing the Human Resources for Health crisis in countries: How far have we gone? What can we expect to achieve by 2015?

The World Health Report 2006 identified 57 countries world-wide whose health worker to population density fell below a critical threshold of 2.3 per 1,000 population. This meant that below this critical threshold, a country could not provide the basic health services to its population, defined here as 80% immunization coverage and 80% skilled birth attendance at delivery. Of the 57 countries, 36 are located in Africa. This article reviews the progress countries have made in addressing their health workforce crisis. It cites 3 of the most recent global studies and the indicators used to measure progress. It also features the experiences of 8 countries, namely Malawi, Peru, Ethiopia, Brazil, Thailand, Philippines, Zambia, Mali. Their situations provide a diverse picture of country efforts, challenges, and successes. The article asks the question of whether the target of 25% reduction in the number of crisis countries can be achieved by 2015. This was a goal set by the World Health Assembly in 2008. While the authors wish to remain optimistic about the striving towards this target, their optimism must be matched by an adequate level of investment in countries on HRH development. The next four years will show how much will really be achieved.

Abordando la crisis de los Recursos Humanos para la Salud: ¿Hasta dónde hemos llegado? ¿Qué podemos esperar lograr al 2015? / Addressing the Human Resources for Health crisis in countries: How far have we gone? What can we expect to achieve by 2015?

El reporte mundial de la Salud del 2006 (World Health Report 2006) ha identificado 57 países en los que la densidad de trabajadores de salud con respecto a la población general se encuentra por debajo del umbral crítico de 2,3 por 1000 habitantes. Esto significa que por debajo de este umbral crítico, un país no sería capaz de brindar los servicios básicos para su población, definidos como el 80 por ciento de coberturas de inmunización y 80 por ciento de atención calificada del parto. De los 57 países, 36 pertenecen al África. Este artículo revisa el progreso realizado por los países para afrontar su crisis de recursos humanos en salud. Cita tres de los estudios mundiales más recientes y los indicadores utilizados para medir el progreso. Asimismo, se presenta la experiencia de ocho países: Malawi, Perú, Etiopía, Brasil, Tailandia, Zambia y Mali. Ello brinda un panorama diverso de esfuerzos, retos y éxitos en cada uno de estos países. El artículo lanza la interrogante sobre si la meta de una reducción del 25 por ciento en el número de países en crisis puede lograrse para el año 2015, objetivo definido por la Asamblea Mundial de la Salud en el 2008. El optimismo que los autores quisieran mantener sobre los esfuerzos orientados a esta meta, debe ir sin embargo a la par con un adecuado nivel de inversión de los países en recursos humanos en salud. Los siguientes cuatro años nos mostrarán cuánto en realidad puede ser logrado.

Evaluated strategies to increase attraction and retention of health workers in remote and rural areas.

The lack of health workers in remote and rural areas is a worldwide concern. Many countries have proposed and implemented interventions to address this issue, but very little is known about the effectiveness of such interventions and their sustainability in the long run. This paper provides an analysis of the effectiveness of interventions to attract and retain health workers in remote and rural areas from an impact evaluation perspective. It reports on a literature review of studies that have conducted evaluations of such interventions. It presents a synthesis of the indicators and methods used to measure the effects of rural retention interventions against several policy dimensions such as: attractiveness of rural or remote areas, deployment/recruitment, retention, and health workforce and health systems performance. It also discusses the quality of the current evidence on evaluation studies and emphasizes the need for more thorough evaluations to support policy-makers in developing, implementing and evaluating effective interventions to increase availability of health workers in underserved areas and ultimately contribute to reaching the United Nations' Millennium Development Goals.

Increasing access to health workers in underserved areas: a conceptual framework for measuring results.

Many countries have developed strategies to attract and retain qualified health workers in underserved areas, but there is only scarce and weak evidence on their successes or failures. It is difficult to compare lessons and measure results from the few evaluations that are available. Evaluation faces several challenges, including the heterogeneity of the terminology, the complexity of the interventions, the difficulty of assessing the influence of contextual factors, the lack of baseline information, and the need for multi-method and multi-disciplinary approaches for monitoring and evaluation. Moreover, the social, political and economic context in which interventions are designed and implemented is rarely considered in monitoring and evaluating interventions for human resources for health. This paper proposes a conceptual framework that offers a model for monitoring and evaluation of retention interventions taking into account such challenges. The conceptual framework is based on a systems approach and aims to guide the thinking in evaluating an intervention to increase access to health workers in underserved areas, from its design phase through to its results. It also aims to guide the monitoring of interventions through the routine collection of a set of indicators, applicable to the specific context. It suggests that a comprehensive approach needs to be used for the design, implementation, monitoring, evaluation and review of the interventions. The framework is not intended to be prescriptive and can be applied flexibly to each country context. It promotes the use of a common understanding on how attraction and retention interventions work, using a systems perspective.

An approach to estimating human resource requirements to achieve the Millennium Development Goals.

In the context of the Millennium Development Goals, human resources represent the most critical constraint in achieving the targets. Therefore, it is important for health planners and decision-makers to identify what are the human resources required to meet those targets. Planning the human resources for health is a complex process. It needs to consider both the technical aspects related to estimating the number, skills and distribution of health personnel for meeting population health needs, and the political implications, values and choices that health policy- and decision-makers need to make within given resources limitations. After presenting an overview of the various methods for planning human resources for health, with their advantages and limitations, this paper proposes a methodological approach to estimating the requirements of human resources to achieve the goals set forth by the Millennium Declaration. The method builds on the service-target approach and functional job analysis.
