Health inequalities by gradients of access to water and sanitation between countries in the Americas, 1990 and 2010 / Gradientes de acceso a agua y saneamiento y desigualdades en salud entre los países de la Región de las Américas, 1990 y 2010

Objective. To explore distributional inequality of key health outcomes as determined by access coverage to water and sanitation (WS) between countries in the Region of the Americas. Methods. An ecological study was designed to explore the magnitude and change-over-time of standard gap and gradient metrics of environmental inequalities in health at the country level in 1990 and 2010 among the 35 countries of the Americas. Access to drinking water and access to improved sanitation facilities were selected as equity stratifies. Five dependent variables were: total and healthy life expectancies at birth, and infant, under-5, and maternal mortality. Results. Access to WS correlated with survival and mortality, and strong gradients were seen in both 1990 and 2010. Higher WS access corresponded to higher life expectancy and healthy life expectancy and lower infant, under-5, and maternal mortality risks. Burden of life lost was unequally distributed, steadily concentrated among the most environmentally disadvantaged, who carried up to twice the burden than they would if WS were fairly distributed. Population averages in life expectancy and specific mortality improved, but whereas absolute inequalities decreased, relative inequalities remained mostly invariant. Conclusions. Even with the Region on track to meet MDG 7 on water and sanitation, large environmental gradients and health inequities among countries remain hidden by Regional averages. As the post-2015 development agenda unfolds, policies and actions focused on health equity—mainly on the most socially and environmentally deprived—will be needed in order to secure the right for universal access to water and sanitation.

Objetivo. Explorar la desigualdad distributiva de resultados clave en salud determinada por la cobertura de acceso a agua y saneamiento (AS) entre países en la Región de las Américas. Métodos. Se diseñó un estudio ecológico para explorar la magnitud y el cambio en el tiempo de métricas estándar de brecha y gradiente de desigualdades ambientales en salud a nivel país en 1990 y 2010 entre los 35 países de las Américas. El acceso a agua potable y el acceso a instalaciones sanitarias mejoradas fueron seleccionados como estratificadores de equidad. Las cinco variables dependientes fueron: expectativa de vida al nacer total y saludable, mortalidad infantil, en menores de cinco años y materna. Resultados. El acceso a AS se correlacionó con la supervivencia y mortalidad y se observaron intensos gradientes tanto en 1990 como en 2010. Un acceso a AS más alto se correspondió con más alta expectativa de vida al nacer total y saludable y con más bajos riesgos de muerte infantil, en menores de 5 años y materna. La carga de vida perdida se distribuyó inequitativamente, concentrándose de manera sostenida entre los más desaventajados ambientalmente, quienes acarrearon hasta dos veces la carga que hubieran acarreado si el acceso a AS hubiese estado equitativamente distribuido. Los promedios poblacionales en la expectativa de vida y la mortalidad específica mejoraron pero, mientras que las desigualdades absolutas se redujeron, las desigualdades relativas se mantuvieron esencialmente invariantes. Conclusiones. Aún cuando la Región está en curso para alcanzar el ODM 7 sobre agua y saneamiento, los promedios regionales siguen ocultando grandes gradients ambientales y desigualdades en salud entre países. A medida que se despliega la agenda de desarrollo post-2015, serán necesarias políticas y acciones orientadas a la equidad en salud —principalmente hacia aquellos con mayor privación social y ambiental— a fin de asegurar el derecho por el acceso universal al agua y saneamiento.

Challenges and opportunities associated with neglected tropical disease and water, sanitation and hygiene intersectoral integration programs.

BACKGROUND: Recent research has suggested that water, sanitation, and hygiene (WASH) interventions, in addition to mass drug administration (MDA), are necessary for controlling and eliminating many neglected tropical diseases (NTDs). OBJECTIVES: This study investigated the integration of NTD and WASH programming in order to identify barriers to widespread integration and make recommendations about ideal conditions and best practices critical to future integrated programs. METHODS: Twenty-four in-depth, semi-structured interviews were conducted with key stakeholders in the global NTD and WASH sectors to identify barriers and ideal conditions in programmatic integration. RESULTS: The most frequently mentioned barriers to WASH and NTD integration included: 1) differing programmatic objectives in the two sectors, including different indicators and metrics; 2) a disproportionate focus on mass drug administration; 3) differences in the scale of funding; 4) siloed funding; and 5) a lack of coordination and information sharing between the two sectors. Participants also conveyed that a more holistic approach was needed if future integration efforts are to be scaled-up. The most commonly mentioned requisite conditions included: 1) education and advocacy; 2) development of joint indicators; 3) increased involvement at the ministerial level; 4) integrated strategy development; 5) creating task forces or committed partnerships; and 6) improved donor support. CONCLUSIONS: Public health practitioners planning to integrate NTD and WASH programs can apply these results to create conditions for more effective programs and mitigate barriers to success. Donor agencies should consider funding more integration efforts to further test the proof of principle, and additional support from national and local governments is recommended if integration efforts are to succeed. Intersectoral efforts that include the development of shared indicators and objectives are needed to foster conditions conducive to expanding effective integration programs.

Water, sanitation, hygiene, and nutrition: successes, challenges, and implications for integration.

OBJECTIVES: This study explores the integration of water, sanitation, and hygiene (WASH) and nutrition programming for improved child health outcomes and aims to identify barriers to and necessary steps for successful integration. METHODS: Sixteen semi-structured in-depth interviews were conducted with key stakeholders from both the WASH and nutrition sectors, exploring barriers to integration and potential steps to more effectively integrate programs. RESULTS: Key barriers included insufficient and siloed funding, staff capacity and interest, knowledge of the two sectors, coordination, and limited evidence on the impact of integrated programs. To achieve more effective integration, respondents highlighted the need for more holistic strategies that consider both sectors, improved coordination, donor support and funding, a stronger evidence base for integration, and leadership at all levels. CONCLUSIONS: Organizations desiring to integrate programs can use these results to prepare for challenges and to know what conditions are necessary for successfully integrated programs. Donors should encourage integration and fund operational research to improve the efficiency of integration efforts. Knowledge among sectors should be shared and incentives should be designed to facilitate better coordination, especially where both sectors are working toward common goals.

Radiology practice in Latin America: a literature review.

OBJECTIVE: To discover the status and structure of radiology in Latin America with respect to the health care systems it is part of, the effects of socioeconomics, the equipment and technology used, technologists and their training, accreditation, and professional organizations. METHODS: Health-related databases and Google Scholar were searched for articles concerning radiology practice in Latin America. Articles were selected based on relevance to the research scope. DISCUSSION: Many regions in Latin America offer little to no access to radiology. Where there is access, the equipment often is old or not functioning, with limited and costly service and maintenance. Most trained technologists live in urban areas. There are no standardized accreditation practices in Latin America. However, forming professional organizations would help promote the practice of radiology and accreditation standards. International cooperative organizations enhance radiology by providing resources and opportunities for cooperation between countries. CONCLUSION: The current status of radiology in Latin America must be determined. This knowledge will help us discover opportunities for cooperation and ways to improve radiology practice. The main need in Latin America is to extend coverage to the underserved population.
