Small-area variation in health care affecting the choice of cesarean delivery: the case of a Colombian health insurer

In the midst of health care reform, Colombia has succeeded in increasing health insurance coverage and the quality of health care. In spite of this, efficiency continues to be a matter of concern, and small-area variations in health care are one of the plausible causes of such inefficiencies. In order to understand this issue, we use individual data of all births from a Contributory-Regimen insurer in Colombia. We perform two different specifications of a multilevel logistic regression model. Our results reveal that hospitals account for 20% of variation on the probability of performing cesarean sections. Geographic area only explains 1/3 of the variance attributable to the hospital. Furthermore, some variables from both demand and supply sides are found to be also relevant on the probability of undergoing cesarean sections. This paper contributes to previous research by using a hierarchical model and by defining hospitals as cluster. Moreover, we also include clinical and supply induced demand variables.

Promoting the health of marginalized populations in Ecuador through international collaboration and educational innovations

This paper examines two innovative educational initiatives for the Ecuadorian public health workforce: a Canadian-funded Masters programme in ecosystem approaches to health that focuses on building capacity to manage environmental health risks sustainably; and the training of Ecuadorians at the Latin American School of Medicine in Cuba (known as Escuela Latinoamericana de Medicina in Spanish). We apply a typology for analysing how training programmes address the needs of marginalized populations and build capacity for addressing health determinants. We highlight some ways we can learn from such training programmes with particular regard to lessons, barriers and opportunities for their sustainability at the local, national and international levels and for pursuing similar initiatives in other countries and contexts. We conclude that educational efforts focused on the challenges of marginalization and the determinants of health require explicit attention not only to the knowledge, attitudes and skills of graduates but also on effectively engaging the health settings and systems that will reinforce the establishment and retention of capacity in low- and middle-income settings where this is most needed.

Analyses of cataract surgery performed by the Unified Health System in Brazil, 2006-2007

Objective. Estimate cataract surgical rates (CSR) for Brazil and each federal unit in 2006 and 2007 based on the number of surgeries performed by the Unified Health System to help plan a comprehensive ophthalmology network in order to eliminate cataract blindness in compliance with the target set by the World Health Organization (WHO) of 3 000 cataract surgeries per million inhabitants per year. Methods. This descriptive study calculates CSR by using the number of cataract surgeries carried out by the Brazilian Unified Health System for each federal unit and estimates the need for cataract surgery in Brazil for 2006-2007, with official population data provided by the Brazilian Institute of Geography and Statistics. The number of cataract surgeries was compared with the WHO target. Results. To reach the WHO goal for eliminating age-related cataract blindness in Brazil, 560 312 cataract surgeries in 2006 and 568 006 surgeries in 2007 needed to be done. In 2006, 179 121 cataract surgeries were done by the Unified Health System, corresponding to a CSR of 959 per million population; in 2007, 223 317 were performed, with a CSR of 1 179. With the Brazilian Council of Ophthalmology estimation of 165 000 surgeries each year by the non-public services, the CSR for Brazil would be 1 842 for 2006 and 2 051 for 2007. The proportions needed to achieve the proposed target were 38.6% in 2006 and 31.6% in 2007. Conclusions. Human resources, technical expertise, and equipment are crucial to reach the WHO goal. Brazil has enough ophthalmologists but needs improved planning and infrastructure in order to eliminate the problem, aspects that require greater financial investment and stronger political commitment.

School health policies and practices in Victoria- a comparison involving socio-economic status

Issue addressed: Health programs have been part of the responsibility of Victorian school education for 90 years. Yet rarely have there been studies to identify what is happening in school health promotion, or what the differences between schools might be, particularly in relation to the socioeconomic status of the school community and whether the school is in a metropolitan or regional area. Methods: In 1997 all Victorian schools (primary and secondary) in the State, Catholic and Independent systems were sent questionnaires in order to promote broader awareness about health promotion, and to identify what health programs, policies and activities the schools believed existed within their school community. A response rate of 43% was achieved, and results were collated under the six domains of the Health Promoting School model as outlined by the Western Pacific Regional Office of the World Health Organisation. Data analysed in this paper compared highest versus lowest quartiles for socioeconomic status (SES), and schools in metropolitan Melbourne versus regional areas. Results: Most differences between schools based on socioeconomic status occurred in secondary schools and were related mainly to environmental policies and practices, use of back packs, the presence of safety policies, involvement of parents in school activities and the provision of services for mental and social health needs. All differences were in favour of the highest SES quartile schools. Environmental policies and procedures, and school-based health and welfare services were present more often in metropolitan schools than in regional and rural schools. Conclusion: Although there were notable differences between schools, the audit results pointed to more similarities than differences between schools in the highest and lowest SES quartiles for health-related policies and practices; there were even fewer differences between metropolitan and non-metropolitan schools. So what: Regardless of the actual advantages and disadvantages schools experience with respect to location or socioeconomic status, it is important to understand that school staff perceive that they can and do have reasonably comprehensive health policies, procedures and practices to address health issues. Nevertheless, clear differences between schools did emerge in certain health areas and findings will assist policy making and the allocation of limited resources.

Playing their part: the role of physical activity and sport in sustaining the health and well being of small rural communities

It is widely recognised that the health of rural Australians is poor in comparison with their urban counterparts. Similarly, the role played by physical activity in maintaining health has been well researched and is well documented. However, little appears to have been published in recent years about the links between physical activity and health in rural communities. The objective of this article was to begin to address that gap. To achieve this, the article drew on research conducted in two small rural communities in Victoria Australia, and highlighted the role that physical activity and sport played in sustaining the health and wellbeing of individuals and communities in rural areas. Taking the World Health Organisation's definition of health (a state of complete physical, mental and social well-being and not merely the absence of disease) as its measure, the paper highlighted the many ways in which physical activity and sport in rural communities contribute to physical health, mental wellbeing and social cohesiveness. Based this finding, the authors suggest that physical activity and sport make a significant contribution to the health and wellbeing of rural people and their communities and suggest that further research is necessary to better define this apparent contribution.

Measuring health in a vacuum: examining the disability weight of the DALY

The Disability Adjusted Life Year (DALY) is a widely used summary measure of population health combining years of life lost due to mortality and years of healthy life lost due to disability. A feature of the DALY is that, in the assessment of morbidity, each health condition is associated with a disability weight. The disability weight lies on a scale between 0 (indicating the health condition is equivalent to full health) and 1 (indicating the health condition is equivalent to death). The disability weight associated with each health condition is currently fixed across all social, cultural and environmental contexts. Thus blindness in the United Kingdom has the same disability weight as blindness in Niger in spite of structural interventions in the UK that make the disability less severe than in Niger. Although the fixed disability weight is defended on grounds that it supports a strongly egalitarian flavour in the DALY, we argue that the lack of consideration of realistic contexts results in a measure that will underestimate the burden associated with morbidity in disadvantaged populations and overestimate the burden in advantaged populations. There is, consequently, a loss of information on possible non-clinical points of intervention. Disaggregated estimates of the burden of disease such as those in the World Health Report 2000 should be interpreted with caution.

Measuring the impact of intimate partner violence on the health of women in Victoria, Australia

Objective: Using burden of disease methodology, estimate the health risks of intimate partner violence (IPV) among women in Victoria, Australia.

Methods: We calculated population attribute fractions (from survey data on the prevalence of IPV and the relative risks of associated health problems in Australia) and determined health outcomes by applying them to disability-adjusted life year estimates for the relevant disease and injury categories for Victoria, Australia for 2001.

Findings: For women of all ages IPV accounted for 2.9% (95% uncertainty interval 2.4-3.4%)  of the total disease and injury burden.  Among women 18-44 years of age, IPV was associated with 7.9% (95% uncertainty interval 6.4-935%) of the overall disease burden and was a larger risk to health than risk factors traditionally included in burden of disease studies, such as raised blood pressure, tobacco use and increased body weight.  Poor mental health contributed 73% and substance abuse 22% to the disease burden attributed to IPV.

Conclusion: Our findings suggest that IPV constitutes a significant risk to women's health.  Mental health policy-makers and health workers treating common mental health problems need to be aware that IPV is an important factor.  Future research should concentrate on evaluating effective interventions to prevent women being exposed to violence, and identifying the most appropriate mental health care for victims to reduce short- and long-term disability

Sustainability and health : supporting global ecological integrity in public health

Radical changes in the biosphere and human interaction with the environment are increasingly impacting on the health of populations across the world. Diseases are crossing the species barrier, and spreading rapidly through globalized transport systems. From new patterns of cancer to the threat of global pandemics, it is imperative that public health practitioners acknowledge the interdependence between the sustainability of the environment and the sustainability of the human species.* Why are issues of global and local sustainability of increasing importance to the public's health?* Why do issues of sustainability require new practices within the professions of public health?* How can future and current public health practitioners develop those new practices?Drawing on scientific evidence of global and local environmental changes, Sustainability and Health offers a thorough background and practical solutions to the overlapping issues in environment and health. It examines potential and existing responses to global and local environment and health issues, involving individuals, community, industry and government. The authors introduce a range of emerging conceptual frameworks and theoretical perspectives, link IT and epidemiology and explain how scoping can link program design, delivery, data collection and evaluation in projects from their very beginning. Public health practitioners need to be able to manage health issues that cut across environmental, economic and social systems and to develop the capacity for leadership in facilitating change. Incorporating learning activities, readings, international case studies and an open learning approach, this is a valuable resource for students of public and environmental health, as well as medical, environmental and health science professionals.

The origins of contemporary primary health care

This chapter begins by exploring the concept of primary health care (PHC), linking this to relevant international and national policy documents, and introducing the concept of PHC developed by the World Health Organization. The chapter then focuses on the UK. It explains how PHC is not just found within the NHS, reviews the different sectors involved in PHC, and then discusses the current structure of PHC in the NHS. Key concepts, including the primary health care team, primary care trusts and integrated heath and social care trusts, and the relevant current UK policy documents are introduced.

The chapter then moves on to discuss four important issues in the provision of primary health care in the community: health promotion; tackling health inequalities; health and regeneration; and, tackling domestic violence. The subsection on each of these will explain why the issue is of particular significance and review briefly a number of studies/projects which illustrate what is happening/can be done; this will introduce a range of current research. The chapter concludes with a short review of challenges for the future, emphasising the important role that the nursing profession has to play in meeting these challenges.

Health literacy revisited : what do we mean and why does it matter?

‘Health literacy’ refers to accessing, understanding and using information to make health decisions. However, despite its introduction into the World Health Organization's Health Promotion Glossary, the term remains a confusing concept. We consider various definitions and measurements of health literacy in the international and Australian literature, and discuss the distinction between the broader concept of ‘health literacy’ (applicable to everyday life) and ‘medical literacy’ (related to individuals as patients within health care settings). We highlight the importance of health literacy in relation to the health promotion and preventive health agenda. Because health literacy involves knowledge, motivation and activation, it is a complex thing to measure and to influence. The development of health literacy policies will be facilitated by better evidence on the extent, patterns and impact of low health literacy, and what might be involved in improving it. However, the current lack of consensus of definitions and measurement of health literacy will first need to be overcome.
