This is the second guidance note in a four-part series of notes related to impact evaluation developed by InterAction with financial support from the Rockefeller Foundation.This second guidance note, Linking Monitoring and Evaluation to Impact Evaluation, illustrates the relationship between routine... M&E and impact evaluation – in particular, how both monitoring and evaluation activities can support meaningful and valid impact evaluation. The guidance note is also available in French, Arabic and Spanish on https://www.interaction.org/impact-evaluation-notes.more
This is the first guidance note in a four-part series of notes produced by InterAction to support management,
program and M&E staff in international NGOs to plan, design, manage, conduct and use impact evaluations. This first guidance note, Introduction to Impact Evaluation, provides an overview of... impact evaluation, explaining how impact evaluation differs from – and complements – other types of evaluation, why impact evaluation should be
done, when and by whom. It describes different methods, approaches and designs that can be used for the different aspects of impact evaluation. The guidance note is also available in French, Arabic and Spanish on https://www.interaction.org/impact-evaluation-notes.more
In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.more
In many of Myanmar’s contested regions, healthcare services are provided through two parallel governance systems – by the government’s Ministry of Health, and by providers linked to ethnic armed organizations. Building upon efforts to build trust between these two actors following ceasefires s...igned in 2011 and 2012, the new National League for Democracy-led government offers an unprecedented opportunity to increase cooperation between these systems and to ensure health services reach Myanmar’s most vulnerable populations.
The report provides an overview of existing health service arrangements in these areas, from both the Ministry of Health and from ethnic and community-based health organizations. It then unpacks the concept of “convergence”, highlighting key opportunities and policy recommendations for both government and non-government actors. more
How should humanitarian organisations prepare and respond to COVID-19 in humanitarian settings in low- and middle-income countries?
This Rapid Learning Review outlines 14 actions, insights and ideas for humanitarian actors to consider in their COVID-19 responses. It summarises and synthesises the... best available knowledge and guidance for developing a health response to COVID-19 in low- and middle-income settings as at April 2020
The paper, supported by the UN Under-Secretary-General for Humanitarian Affairs and Emergency Relief Coordinator Mark Lowcock, will be updated throughout 2020 to reflect emerging knowledge and evidence on the most effective approaches to respond to the COVID-19 Pandemic.more
The Core Elements of Outpatient Antibiotic Stewardship provides a framework for antibiotic stewardship for outpatient clinicians and facilities that routinely provide antibiotic treatment. This report augments existing guidance for other clinical settings. In 2014 and 2015, respectively, CDC release...d the Core Elements of Hospital Antibiotic Stewardship Programs and the Core Elements of Antibiotic Stewardship for Nursing Homes. Antibiotic stewardship is the effort to measure and improve how antibiotics are prescribed by clinicians and used by patients. Improving antibiotic prescribing involves implementing effective strategies to modify prescribing practices to align them with evidence-based recommendations for diagnosis and management.more
El VIH/sida, desconocido 30 años atrás, se ha constituido en un problema de salud
mundial de una magnitud sin precedentes, considerándose que aproximadamente 25 millones de personas han fallecido en todo el mundo a causa del VIH.

Many commercial actors use a range of coordinated and sophisticated strategies to protect business interests— their corporate playbook—but many of these strategies come at the expense of public h...ealth. To counter this corporate playbook and advance health and wellbeing, public health actors need to develop, refine, and modernise their own set of strategies, to create a public health playbook. In this Viewpoint, we seek to consolidate thinking around how public health can counter and proactively minimise powerful commercial influences.more
Germany’s overall response to COVID-19 has been evaluated as reasoned and sound. Nonetheless, it has exposed weaknesses and blindspots in the German healthcare system regarding the inclusion of migrant groups. For instance, marginalised groups such as labour migrants and asylum-seekers are not con...sidered for tailored measures in the government’s response to COVID-19. On the other hand, certain efforts to include migrant groups, such as the provision of information in numerous languages, are unprecedented in the German context. They may point to increasing accommodation for diversity.more
This guidance document provides basic broad principles for a spokesperson

A detailed overview is provided of the implementation of alcohol policies described in the 10 action areas of the European Action Plan ...to Reduce the Harmful Use of Alcohol 2012–2020 (EAPA), including the current status of implementation of the five action areas of the WHO-led SAFER initiative:
Strengthen restrictions on alcohol availability;
Advance and enforce drink–driving countermeasures;

Este documento apresenta um marco conceitual renovado das funções essenciais de saúde pública (FESP) para a Região das Américas, com o qual se pretende dar maior clareza conceitual e operacionalidade ao novo campo de atuação da saúde pública e preencher uma lacuna nas propostas conceituais... sobre o fortalecimento dos sistemas de saúde. O marco proposto apresenta um novo paradigma para a saúde pública, baseado em quatro pilares orientados para a ação: a necessidade de incorporar a abordagem dos direitos humanos às políticas públicas de saúde; a necessidade de a saúde pública ampliar seu enfoque para ter uma abordagem mais ampla dos determinantes sociais da saúde; o papel da saúde pública para garantir de forma integral e integrada o acesso a intervenções de base populacional e atenção individual de qualidade; e a necessidade de as autoridades de saúde atuarem em colaboração com outros setores e com a sociedade civil no desempenho das funções de saúde pública.more
Unchecked inequality and failure to protect the rights of poorest women could undermine peace and world’s development goals, new UNFPA report warns:
