How prepared is Europe for pandemic influenza? Analysis of national plans

BACKGROUND The threat of a human pandemic of influenza has prompted urgent development of national preparedness plans. We assessed these plans, to judge Europes preparedness for pandemic influenza. METHODS Published national pandemic influenza preparedness plans from the European Union countries, the two acceding countries (Bulgaria and Romania), Norway, and Switzerland, were evaluated against criteria taken from a WHO checklist. Plans were eligible for inclusion if formally published between Jan 1, 2002, and Nov 30, 2005. FINDINGS 21 national plans were eligible for inclusion for analysis. Although preparation for surveillance, planning and coordination, and communication were good, maintenance of essential services, putting plans into action, and public-health interventions were probably inadequate. Few countries have addressed in their plans the need for collaboration with adjacent countries, despite this being an acknowledged imperative. Similarly, plans for the timely distribution of available medical supplies are notably absent. INTERPRETATION Governmental commitment in most European countries is strong, and levels of preparedness are broadly good. However, gaps in preparedness planning remain, and substantial variations exist between countries, with important implications for the region and nation states. Improved cooperation between countries may be needed to share experience, and to ensure coherence of approaches.

Towards a conceptual framework to support one-health research for policy on emerging zoonoses.

Summary In the past two decades there has been a growing realisation that the livestock sector was in a process of change, resulting from an expansion of intensive animal production systems and trade to meet a globalised worlds increasing demand for livestock products. One unintended consequence has been the emergence and spread of transboundary animal diseases and, more specifically, the resurgence and emergence of zoonotic diseases. Concurrent with changes in the livestock sector, contact with wildlife has increased. This development has increased the risk of transmission of infections from wildlife to human beings and livestock. Two overarching questions arise with respect to the real and perceived threat from emerging infectious diseases: why are these problems arising with increasing frequency, and how should we manage and control them? A clear conceptual research framework can provide a guide to ensure a research strategy that coherently links to the overarching goals of policy makers. We propose such a new framework in support of a research and policy-generation strategy to help to address the challenges posed by emerging zoonoses.

Late diagnosis of HIV in Europe: definitional and public health challenges.

Abstract With universal access to antiretroviral therapy (ART), people can access effective treatment but are only able to benefit from these advances if they are aware of their status and are effectively accessing testing services. Although it was anticipated in the mid-1990s that the availability of ART would lead to earlier testing, this trend has not been observed in practice, with stagnant or even increasing rates of late diagnosis in Europe. Ahead of a gathering of key European stakeholders in Brussels in November 2007, we reviewed definitions of late diagnosis and approaches to surveillance of late HIV diagnosis in Europe. We found that there is no common or consistent reporting of late diagnosis across Europe and that the multiplicity of definitions for late diagnosis is likely proving a hindrance to providing information on the magnitude of the problem, determining trends, and informing understanding of reasons for changes in trends. We also show that existing evidence points to high rates of late diagnosis across Europe – between 15 and 38% of all HIV cases – and concur that trends that are increasing or at best stagnant. We identify risk factors that are associated with individuals being more likely to present late and we explore the reasons for late presentation. We reflect on the need to review surveillance and testing policies, notably in relation for population groups that are heavily represented in late presenters and make recommendations for a coherent, cross-European approach to surveillance and monitoring in order to support improvements in service provision and, ultimately, public health.

HIV testing strategies across European countries.

With universal access to effective combination antiretroviral therapy (ART), people in need can gain effective treatment but are only able to benefit from these advances if they are aware of their serostatus and have effectively accessed testing services. Despite the expectation that ART would lead individuals to seek earlier testing, this trend has not been observed in practice, with stable or even increasing rates of late diagnosis in Europe being witnessed. Ahead of a gathering of key European stakeholders in Brussels in November 2007, we reviewed testing strategies across European countries. We show differences in policy and practices. Moreover, HIV testing strategies are changing, in line with new global guidelines issued by World Health Organization headquarters, and a number of countries are promoting an expansion of routine and opt‐out testing. However, gaps in our understanding of effective testing strategies remain and, as a consequence, national policies across Europe remain incoherent and often lack an evidence base. This is likely to have serious public health implications.

Pandemic influenza preparedness in Africa is a profound challenge for an already distressed region: analysis of national preparedness plans

Abstract A new highly pathogenic strain of influenza virus, H5N1, has emerged causing severe outbreaks in poultry and high mortality rates when humans are infected. The threat of a new influenza pandemic has prompted countries to draft national strategic preparedness plans to prevent, contain and mitigate the next human influenza pandemic. To evaluate preparedness for an influenza pandemic in the African region we analysed African national preparedness plans available in the public domain. A data extraction tool, based on a World Health Organization checklist for influenza epidemic preparedness, was designed in consultation with pandemic influenza planning experts and experts on the regions public health challenges. Thirty-five plans were identified and available from 53 African countries. Most plans are relatively robust in addressing detection and containment of influenza in animals but strategic preparedness to respond to pandemic human influenza is weak. In most plans communication strategies have been developed with the aim to raise awareness of transmission factors and promote hygiene measures. By contrast, the human health care sector is ill-prepared. Case management, triage procedures, identification of health care facilities for patient treatment (including home care and provisions for the distribution and administration of pharmaceuticals) are poorly addressed by most plans. The maintenance of essential services in the event of a pandemic is absent from most plans. Whilst many African countries have strategic pandemic influenza preparedness plans, most are developmental in nature and lack operational clarity, or focus principally on the containment of avian influenza rather than pandemic human influenza. Clear strategies, that are operational, need to be developed that reflect the realities of national context and resource constraints and that meet national objectives. These objectives need also to be coherent with international imperatives such that the global threat of pandemic influenza can be met effectively and efficiently.

Impact of Measles Elimination Activities on Immunization Services and Health Systems: Findings From Six Countries

BACKGROUND One of the key concerns in determining the appropriateness of establishing a measles eradication goal is its potential impact on routine immunization services and the overall health system. The objective of this study was to evaluate the impact of accelerated measles elimination activities (AMEAs) on immunization services and health systems in 6 countries: Bangladesh, Brazil, Cameroon, Ethiopia, Tajikistan, and Vietnam. METHODS Primary data were collected from key informant interviews and staff profiling surveys. Secondary data were collected from policy documents, studies, and reports. Data analysis used qualitative approaches. RESULTS This study found that the impact of AMEAs varied, with positive and negative implications in specific immunization and health system functions. On balance, the impacts on immunization services were largely positive in Bangladesh, Brazil, Tajikistan, and Vietnam, while negative impacts were more significant in Cameroon and Ethiopia. CONCLUSIONS We conclude that while weaker health systems may not be able to benefit sufficiently from AMEAs, in more developed health systems, disruptions to health service delivery are unlikely to occur. Opportunities to strengthen the routine immunization service and health system should be actively sought to address system bottlenecks in order to incur benefits to eradication program itself as well as other health priorities.

Pandemic influenza preparedness and health systems challenges in Asia: results from rapid analyses in 6 Asian countries

BackgroundSince 2003, Asia-Pacific, particularly Southeast Asia, has received substantial attention because of the anticipation that it could be the epicentre of the next pandemic. There has been active investment but earlier review of pandemic preparedness plans in the region reveals that the translation of these strategic plans into operational plans is still lacking in some countries particularly those with low resources. The objective of this study is to understand the pandemic preparedness programmes, the health systems context, and challenges and constraints specific to the six Asian countries namely Cambodia, Indonesia, Lao PDR, Taiwan, Thailand, and Viet Nam in the prepandemic phase before the start of H1N1/2009.MethodsThe study relied on the Systemic Rapid Assessment (SYSRA) toolkit, which evaluates priority disease programmes by taking into account the programmes, the general health system, and the wider socio-cultural and political context. The components under review were: external context; stewardship and organisational arrangements; financing, resource generation and allocation; healthcare provision; and information systems. Qualitative and quantitative data were collected in the second half of 2008 based on a review of published data and interviews with key informants, exploring past and current patterns of health programme and pandemic response.ResultsThe study shows that health systems in the six countries varied in regard to the epidemiological context, health care financing, and health service provision patterns. For pandemic preparation, all six countries have developed national governance on pandemic preparedness as well as national pandemic influenza preparedness plans and Avian and Human Influenza (AHI) response plans. However, the governance arrangements and the nature of the plans differed. In the five developing countries, the focus was on surveillance and rapid containment of poultry related transmission while preparation for later pandemic stages was limited. The interfaces and linkages between health system contexts and pandemic preparedness programmes in these countries were explored.ConclusionHealth system context influences how the six countries have been preparing themselves for a pandemic. At the same time, investment in pandemic preparation in the six Asian countries has contributed to improvement in health system surveillance, laboratory capacity, monitoring and evaluation and public communications. A number of suggestions for improvement were presented to strengthen the pandemic preparation and mitigation as well as to overcome some of the underlying health system constraints.

National decision-making on adopting new vaccines: a systematic review

In recent years numerous new vaccines have been developed, offering potential reductions in the morbidity and mortality caused by a range of diseases. This has led to increased interest in decision-making about the adoption of new vaccines into national immunization programmes. This paper aims to systematically review the literature on national decision-making around the adoption of new vaccines. A thematic framework was developed inductively through analysis of the vaccine adoption decision-making frameworks included in the review. This thematic framework was then applied to the remaining studies included in the review. In total, 85 articles were included in the review: 39 articles describing examples of vaccine adoption decision-making, 26 presenting vaccine decision-making frameworks, 21 empirical articles of decision-making relating to vaccine adoption and 19 theoretical essays. An analysis of vaccine adoption decision-making frameworks identified nine broad categories of criteria: the importance of the health problem; vaccine characteristics; immunization programme considerations; acceptability; accessibility, equity and ethics; financial/economic issues; impact; alternative interventions and the decision-making process. The quality of the empirical studies was varied. Although some of the issues included in the frameworks were similar to those considered in the studies, there were also some notable differences. On the whole, the frameworks were more comprehensive than the studies, including a greater range of criteria. The existing literature provides a good foundation for further research into vaccine adoption decision-making. The current review, in pulling together what is already known and by identifying strengths, weaknesses and gaps in the existing evidence base, aims to encourage a more focused and rigorous approach to the topic in future. This could help to identify the most appropriate ways to develop vaccine adoption decision-making, so as to improve decisions and, ultimately, health outcomes.

New vaccine adoption: qualitative study of national decision-making processes in seven low- and middle-income countries

As more new and improved vaccines become available, decisions on which to adopt into routine programmes become more frequent and complex. This qualitative study aimed to explore processes of national decision-making around new vaccine adoption and to understand the factors affecting these decisions. Ninety-five key informant interviews were conducted in seven low- and middle-income countries: Bangladesh, Cameroon, Ethiopia, Guatemala, Kenya, Mali and South Africa. Framework analysis was used to explore issues both within and between countries. The underlying driver for adoption decisions in GAVI-eligible countries was the desire to seize GAVI windows of opportunity for funding. By contrast, in South Africa and Guatemala, non-GAVI-eligible countries, the decision-making process was more rooted in internal and political dynamics. Decisions to adopt new vaccines are, by nature, political. The main drivers influencing decisions were the availability of funding, political prioritization of vaccination or the vaccine-preventable disease and the burden of disease. Other factors, such as financial sustainability and feasibility of introduction, were not as influential. Although GAVI procedures have established more formality in decision-making, they did not always result in consideration of all relevant factors. As familiarity with GAVI procedures increased, questioning by decision-makers about whether a country should apply for funding appeared to have diminished. This is one of the first studies to empirically investigate national processes of new vaccine adoption decision-making using rigorous methods. Our findings show that previous decision-making frameworks (developed to guide or study national decision-making) bore little resemblance to real-life decisions, which were dominated by domestic politics. Understanding the realities of vaccine policy decision-making is critical for developing strategies to encourage improved evidence-informed decision-making about new vaccine adoptions. The potential for international initiatives to encourage evidence-informed decision-making should be realised, not assumed.

Pandemic influenza preparedness in Latin America: analysis of national strategic plans.

Abstract The threat of a human pandemic of influenza has prompted the development of national influenza pandemic preparedness plans over the last 4 years. Analyses have been carried out to assess preparedness in Europe, Asia and Africa. We assessed plans to evaluate the national strategic pandemic influenza preparedness in the countries of Latin America. Published national pandemic influenza preparedness plans from Latin American countries were evaluated against criteria drawn from the World Health Organization checklist. Plans were eligible for inclusion if formally published before 16 November 2007. Fifteen national plans were identified and retrieved from the 17 Latin American countries surveyed. Latin American countries demonstrated different degrees of preparedness, and that a high level of completeness of plans was correlated to a countrys wealth to a certain extent. Plans were judged strong in addressing surveillance requirements, and provided appropriate communication strategies directed to the general public and health care personnel. However, gaps remained, including the organization of health care services’ response; planning and maintenance of essential services; and the provision of containment measures such as the stockpiling of necessary medical supplies including vaccines and antiviral medications. In addition, some inconsistencies and variations which may be important, such as in border control measures and the capacity to contain outbreaks, exist between country plans—issues that could result in confusion in the event of a pandemic. A number of plans remain developmental in nature and, as elsewhere, more emphasis should be placed on strengthening the operability of plans, and in testing them. Whilst taking account of resources constraints, plans should be further developed in a coherent manner with both regional and international imperatives.
