The Right to Healthcare Must Include the Right to Ease of Physical Access: Exploring Geography-Health Nexus in GIDA Communities in the Philippines

Using the United Nations' 'leave no one behind' framework for the achievement of sustainable development goals, this article underscores the key role of geography as one of the core factors why certain people are left behind, deprived, and continue to experience inequality in terms of access to (quality) health care facilities and services. This article specifically examines the consequences of physical inaccessibility to health outcomes and health-seeking behavior in geographically isolated and disadvantaged areas (GIDAs) in the Philippines. This article illustrates that physical accessibility is an ignored aspect of the public health paradigm. For that reason, public health facilities, no matter how critical the facility is to a person's care, are not an immediate option for GIDA residents who seek medical aid. Responsive policy measures are vital to address this seemingly paradigmatic error. Subsidizing transportation costs and allocating funds for road improvements are called for, among other changes. The government must act on the people's right to ease of access as part of fulfilling fundamental health-related state obligations. But for the government to act, it will be crucial for claimants to health rights to proactively demand these changes. The latter is key for the fulfillment of the affected people's right to get easier access to meaningful health care.

Equality of public health service and family doctor contract service utilisation among migrants in China

China initiated the equalisation of an essential public health service programme in 2009 with the goal of developing a more equitable and effective public health system for all people. This study employs data from the China Migrants Dynamic Survey to examine regional-level and household-level income-related inequalities in public health service utilisation and its determinants. Wagstaff concentration indices indicate that essential public health services and family doctor contract services are concentrated among less developed prefectures and poorer households. Decomposition analysis based on recentered influence function regression shows that education contributes to pro-poor inequality in health records and health education utilisation. China's policies of essential public health services and family doctor contract services reduce income-related inequalities in health service utilisation, which has important implications for developing countries striving to achieve universal health service coverage and equal health outcomes.

The social value of health: Amenable deaths and estimated the gap with the life expectancy frontier

We estimate the life expectancy gaps that can be bridged by improving the quality of public health and health care policies at the country level. Our model calculates the net effect of amenable deaths on life expectancy after controlling for time effects and factors affecting amenable deaths related to education, health policies (health expenditure to GDP and waiting lists), and per capita income in a two equation system. We further estimate the life expectancy gap that countries with lower quality health systems can bridge by catching up and reaching the existing health quality frontier and compute the social value of that upside potential.

Perspectives on the current state of Nigeria's emergency care system among participants of an emergency medicine symposium: a qualitative appraisal

INTRODUCTION

Emergency care systems provide timely and relevant care to the acutely ill and injured. Published commentaries have characterised deficiencies in the Nigerian emergency care system and offered potential solutions but have not included the perspectives of the Nigerian public. A more inclusive approach that includes feedback from the public may help improve the Nigerian emergency care system through better understanding of the needs, values and expectations of the community.

METHODS

Participants of an emergency medicine symposium participated in focus group discussions that were randomly divided into small groups led by two trained facilitators. These facilitators asked open-ended, semistructured questions to lead discussions in the English language. Participant responses were audio-recorded and transcribed verbatim into transcripts. Two independent investigators employed conventional content analysis to code the transcripts until thematic saturation was achieved.

RESULTS

Three descriptive themes emerged characterising the current state of Nigeria's emergency care system as it relates to prehospital care delivery, hospital care delivery and health system governance: rudimentary, vulnerable and disconnected. At the prehospital level, concepts revolved around emergency recognition and response, ambulance and frontline providers, and cultural norms. At the hospital level, concepts centred around the health workforce, clinical competency, hospital capacity and the burden of financial hardship. At the health system level, concepts concentrated on healthcare access and healthcare financing. Opportunities for emergency care system improvement at each component level were identified and explored.

CONCLUSIONS

The participants in this study identified shortcomings and opportunities to improve prehospital care, hospital care and health system governance. The results of this study may help healthcare professionals, policy makers and community leaders identify gaps in the emergency care system and offer solutions in harmony with the needs, values and expectations of the community. If successful, these community-informed interventions may serve as a model to improve emergency care systems throughout Africa.

Impact of patient portal behavioral engagement on subsistence consumers' wellbeing☆

Subsistence consumers, representing almost half the global population, live on low incomes, possess low levels of literacy, and generally experience poor health. Technology is a tool used to facilitate stronger connections between consumers and support services, including for subsistence consumers. Given the unique characterization of subsistence marketplaces, research needs to examine potential associations between subsistence consumers' individual resource integration and wellbeing via their behavioral engagement with technologies. Research is also warranted that investigates the factors that can moderate this association. A 45-day customized patient portal app was delivered via 26 healthcare service providers, resulting in the surveying of 336 subsistence consumers who used the portal. The results indicate positive associations between subsistence consumers' individual resource integration, patient portal behavioral engagement, and wellbeing. They also indicate that these associations are strengthened by service provider's resource support and subjective norms, and weakened by medical mistrust. Theoretical and managerial implications from this study's findings are discussed.

•

Fills key research gaps via a patient portal field study of subsistence consumers.

•

Individual resource integration acts as an antecedent to behavioral engagement.

•

Behavioral engagement positively impacts on subsistence consumers' wellbeing.

•

Provider resource support, subjective norms, and medical mistrust act as moderators.

•

Informs practitioners about engagement-led technologies in a subsistence context.

Micropipette Tip-Based Immunoassay with Electrochemical Detection of Antitissue Transglutaminase to Diagnose Celiac Disease Using Staples and a Paper-Based Platform

In this work, 1-200 μL polypropylene micropipette tips were used as platforms for performing immunoassays after converting their inner surfaces on a capture zone for the analyte of interest. We have used a micropipette-tip immunoelectroanalytical platform for the detection of antitissue transglutaminase (IgA), the main biomarker for celiac disease. Modification of the tip wall with poly-l-lysine allowed adsorption of tissue transglutaminase (tTG), which will capture later anti-tTG (IgA) antibodies developed in celiac-affected people. A sandwich-type format was followed, incubating simultaneously the analyte and the detection antibody, labeled with horseradish peroxidase. With this new application for an extremely common lab material, we can perform quantitative analysis by dispensing the liquid into a low-cost and miniaturized staple-based paper electrochemical platform. The analytical signal was the reduction of the enzymatically oxidized substrate, recorded chronoamperometrically (i-t curve). The intensity of the current obtained at a fixed time after the application of the cathodic potential followed a linear relationship with anti-tTG (IgA) concentration. The relative standard deviation obtained for immunoassays performed in different tips indicates the adequate precision of this new methodology, which is very promising for decentralized analysis. Negative and positive controls produced results that were in accordance with those obtained with spectrophotometric enzyme linked-immunosorbent assays.

The slowing pace of life expectancy gains since 1950

Background

New technological breakthroughs in biomedicine should have made it easier for countries to improve life expectancy at birth (LEB). This paper measures the pace of improvement in the decadal gains of LEB, for the last 60-years adjusting for each country’s starting point of LEB.

Methods

LEB increases over the next 10-years for 139 countries between 1950 and 2009 were regressed on LEB, GDP, total fertility rate, population density, CO2 emissions, and HIV prevalence using country-specific fixed effects and time-dummies. Analysis grouped countries into one-of-four strata: LEB < 51, 51 ≤ LEB < 61, 61 ≤ LEB < 71, and LEB ≥ 71.

Results

The rate of increase of LEB has fallen consistently since 1950 across all strata. Results hold in unadjusted analysis and in the regression-adjusted analysis. LEB decadal gains fell from 4.80 (IQR: 2.98–6.20) years in the 1950s to 2.39 (IQR:1.80–2.80) years in the 2000s for the healthiest countries (LEB ≥ 71). For countries with the lowest LEB (LEB < 51), decadal gains fell from 7.38 (IQR:4.83–9.25) years in the 1950s to negative 6.82 (IQR: -12.95--1.05) years in the 2000s. Multivariate analysis controlling for HIV prevalence, GDP, and other covariates shows a negative effect of time on LEB decadal gains among all strata.

Conclusions

Contrary to the expectation that advances in health technology and spending would hasten improvements in LEB, we found that the pace-of-growth of LEB has slowed around the world.

Individual and Medical Characteristics of Adults Presenting to an Urban Emergency Department in Ghana

BACKGROUND

The aims of this study were to characterize the patients seeking acute care for injury and non-injury complaints in an urban Emergency Department in Ghana in order to 1) inform the curriculum of the newly developed Emergency Medicine resident training program 2) improve treatment processes, and 3) direct future community-wide injury prevention policies.

STUDY DESIGN

A prospective cross-sectional survey of patients 18 years or older seeking care in an urban Accident and Emergency Center (AEC) was conducted between 7/13/2009 and 7/30/2009. Questionnaires were administered by trained research staff and each survey took 10-15 minutes to complete. Patients were asked questions regarding demographics, overall health and chief complaint.

RESULTS

254 patients were included in the sample. Participants' chief complaints were classified as either medical or injury-related. Approximately one third (38%) of patients presented with injuries and 62% presented for medical complaints. The most common injury at presentation was due to a road traffic injury, followed by falls and assault/fight. The most common medical presentation was abdominal pain followed by difficulty breathing and fainting/ blackout. Only 13% arrived to AEC by ambulance and 51% were unable to ambulate at the time of presentation.

CONCLUSION

Approximately one-third of non-fatal adult visits were for acute injury. Future research should focus on developing surveillance systems for both medical and trauma patients. Physicians that are specifically trained to manage both the acutely injured patient and the medical patient will serve this population well given the variety of patients that seek care at the AEC.

Combining risk factors and demographic surveillance: Potentials of WHO STEPS and INDEPTH methodologies for assessing epidemiological transition

Aims: Demographic surveillance systems (DSSs) create platforms to monitor population dynamics. This paper discusses the potential of combining the WHO STEPwise approach to Surveillance (STEPS) within ongoing DSSs, to assess changes in non-communicable disease (NCD) risk factors. Methods: Three DSSs in Ethiopia, Vietnam, and Indonesia have collected NCD risk factors using WHO STEPS, focusing on self-reported lifestyle risk factors (Step 1) and measurement of blood pressure and anthropometric parameters (Step 2). Results: DSSs provide sampling frames for NCD risk factor surveillance, which reveals the distribution of risk factors and their dynamics at the population level. The WHO STEPS approach with its add-on modules is feasible and adaptable in DSS settings. Available mortality data in the DSSs enable mortality assessment by cause of death using verbal autopsy, which is relevant in estimating the impact of NCDs. DSSs as well as risk factor surveillance data may potentially be a lever for hypothesis-driven research to address specific a priori hypotheses or research questions. Conclusion: Combining DSSs with the WHO STEPS approach can potentially address basic epidemiological questions on NCDs, which can be used as a powerful advocacy tool in public health decision-making for NCD prevention.

“Please Don’t Send Us Spam!” A Participative, Theory-Based Methodology for Developing an mHealth Intervention

Background

Mobile health solutions have the potential of reducing burdens on health systems and empowering patients with important information. However, there is a lack of theory-based mHealth interventions.

Objective

The purpose of our study was to develop a participative, theory-based, mobile phone, audio messaging intervention attractive to recently circumcised men at voluntary medical male circumcision (VMMC) clinics in the Cape Town area in South Africa. We aimed to shift some of the tasks related to postoperative counselling on wound management and goal setting on safe sex. We place an emphasis on describing the full method of message generation to allow for replication.

Methods

We developed an mHealth intervention using a staggered qualitative methodology: (1) focus group discussions with 52 recently circumcised men and their partners to develop initial voice messages they felt were relevant and appropriate, (2) thematic analysis and expert consultation to select the final messages for pilot testing, and (3) cognitive interviews with 12 recent VMMC patients to judge message comprehension and rank the messages. Message content and phasing were guided by the theory of planned behavior and the health action process approach.

Results

Patients and their partners came up with 245 messages they thought would help men during the wound-healing period. Thematic analysis revealed 42 different themes. Expert review and cognitive interviews with more patients resulted in 42 messages with a clear division in terms of needs and expectations between the initial wound-healing recovery phase (weeks 1–3) and the adjustment phase (weeks 4–6). Discussions with patients also revealed potential barriers to voice messaging, such as lack of technical knowledge of mobile phones and concerns about the invasive nature of the intervention. Patients’ own suggested messages confirmed Ajzen’s theory of planned behavior that if a health promotion intervention can build trust and be relevant to the recipient’s needs in the first contacts, then the same recipients will perceive subsequent motivational messages more favorably. The health action process approach was also a useful tool for guiding the phasing of the messages. Participants were more positive and salutogenic than public health experts.

Conclusions

The system showed how a process of consultation can work with a set of potential recipients of an mHealth service to ensure that their needs are included. Classic behavioral theories can and should be used to design modern mHealth interventions. We also believe that patients are the best source of messaging, ensuring that messages are culturally relevant and interesting to the recipient.

Aetiological role of common respiratory viruses in acute lower respiratory infections in children under five years: A systematic review and meta-analysis

Background

Acute lower respiratory infection (ALRI) remains a major cause of childhood hospitalization and mortality in young children and the causal attribution of respiratory viruses in the aetiology of ALRI is unclear. We aimed to quantify the absolute effects of these viral exposures.

Methods

We conducted a systematic literature review (across 7 databases) of case–control studies published from 1990 to 2014 which investigated the viral profile of 18592 children under 5 years with and without ALRI. We then computed a pooled odds ratio and virus–specific attributable fraction among the exposed of 8 common viruses – respiratory syncytial virus (RSV), influenza (IFV), parainfluenza (PIV), human metapneumovirus (MPV), adenovirus (AdV), rhinovirus (RV), bocavirus (BoV), and coronavirus (CoV).

Findings

From the 23 studies included, there was strong evidence for causal attribution of RSV (OR 9.79; AFE 90%), IFV (OR 5.10; AFE 80%), PIV (OR 3.37; AFE 70%) and MPV (OR 3.76; AFE 73%), and less strong evidence for RV (OR 1.43; AFE 30%) in young children presenting with ALRI compared to those without respiratory symptoms (asymptomatic) or healthy children. However, there was no significant difference in the detection of AdV, BoV, or CoV in cases and controls.

Conclusions

This review supports RSV, IFV, PIV, MPV and RV as important causes of ALRI in young children, and provides quantitative estimates of the absolute proportion of virus–associated ALRI cases to which a viral cause can be attributed.

Process evaluation of community monitoring under national health mission at Chandigarh, union territory: Methodology and challenges

BACKGROUND

Community monitoring was introduced on a pilot mode in 36 selected districts of India in a phased manner. In Chandigarh, it was introduced in the year 2009-2010. A preliminary evaluation of the program was undertaken with special emphasis on the inputs and the processes.

METHODOLOGY

Quantitative methods included verification against checklists and record reviews. Nonparticipant observation was used to evaluate the conduct of trainings, interviews, and group discussions. Health system had trained health system functionaries (nursing students and Village Health Sanitation Committee [VHSC] members) to generate village-based scorecards for assessing community needs. Community needs were assessed independently for two villages under the study area to validate the scores generated by the health system.

RESULTS

VHSCs were formed in all 22 villages but without a chairperson or convener. The involvement of VHSC members in the community monitoring process was minimal. The conduct of group discussions was below par due to poor moderation and unequal responses from the group. The community monitoring committees at the state level had limited representation from the non-health sector, lower committees, and the nongovernmental organizations/civil societies. Agreement between the report cards generated by the investigator and the health system in the selected villages was found to be to be fair (0.369) whereas weighted kappa (0.504) was moderate.

CONCLUSION

In spite of all these limitations and challenges, the government has taken a valiant step by trying to involve the community in the monitoring of health services. The dynamic nature of the community warrants incorporation of an evaluation framework into the planning of such programs.

Progress and challenges of disaster health management in China: a scoping review

Background

Despite the importance of an effective health system response to various disasters, relevant research is still in its infancy, especially in middle- and low-income countries.

Objective

This paper provides an overview of the status of disaster health management in China, with its aim to promote the effectiveness of the health response for reducing disaster-related mortality and morbidity.

Design

A scoping review method was used to address the recent progress of and challenges to disaster health management in China. Major health electronic databases were searched to identify English and Chinese literature that were relevant to the research aims.

Results

The review found that since 2003 considerable progress has been achieved in the health disaster response system in China. However, there remain challenges that hinder effective health disaster responses, including low standards of disaster-resistant infrastructure safety, the lack of specific disaster plans, poor emergency coordination between hospitals, lack of portable diagnostic equipment and underdeveloped triage skills, surge capacity, and psychological interventions. Additional challenges include the fragmentation of the emergency health service system, a lack of specific legislation for emergencies, disparities in the distribution of funding, and inadequate cost-effective considerations for disaster rescue.

Conclusions

One solution identified to address these challenges appears to be through corresponding policy strategies at multiple levels (e.g. community, hospital, and healthcare system level).

Evaluating international research ethics capacity development: an empirical approach

The US national institutes of health, Fogarty International Center (NIH-FIC) has, for the past 13 years, been a leading funder of international research ethics education for resource-limited settings. Nearly half of the NIH-FIC funding in this area has gone to training programs that train individuals from sub-Saharan Africa. Identifying the impact of training investments, as well as the potential predictors of post-training success, can support curricular decisionmaking, help establish funding priorities, and recognize the ultimate outcomes of trainees and training programs. Comprehensive evaluation frameworks and targeted evaluation tools for bioethics training programs generally, and for international research ethics programs in particular, are largely absent from published literature. This paper shares an original conceptual framework, data collection tool, and detailed methods for evaluating the inputs, processes, outputs, and outcomes of research ethics training programs serving individuals in resource-limited settings. This paper is part of a collection of papers analyzing the Fogarty International Center's International Research Ethics Education and Curriculum Development program.

Political commitment to tuberculosis control in Ghana

As part of expanding and sustaining tuberculosis (TB) control, the Stop TB Partnership of the World Health Organization initiative has called for strong political commitment to TB control, particularly in developing countries. Framing political commitment within the theoretical imperatives of the political economy of health, this study explores the existing and the expected dimensions of political commitment to TB control in Ghana. Semi-structured in-depth interviews were conducted with 29 purposively selected staff members of the Ghana Health Service and some political officeholders. In addition, the study analysed laws, policies and regulations relevant to TB control. Four dimensions of political commitment emerged from the interviews: provision of adequate resources (financial, human and infrastructural); political authorities' participation in advocacy for TB; laws and policies' promulgation and social protection interventions. Particularly in respect to financial resources, donors such as the Global Fund to Fight AIDS, Tuberculosis and Malaria presently give more than 60% of the working budget of the programme. The documentary review showed that laws, policies and regulations existed that were relevant to TB control, albeit they were not clearly linked.

Maternity waiting homes and traditional midwives in rural Liberia

OBJECTIVE

Maternity waiting homes (MWHs) can reduce maternal morbidity and mortality by increasing access to skilled birth attendants (SBAs). The present analysis was conducted to determine whether MWHs increase the use of SBAs at rural primary health clinics in Liberia; to determine whether traditional midwives (TMs) are able to work with SBAs as a team and to describe the perceptions of TMs as they engage with SBAs; and to determine whether MWHs decrease maternal and child morbidity and mortality.

METHODS

The present analysis was conducted halfway through a large cohort study in which 5 Liberian communities received the intervention (establishment of an MWH) and 5 Liberian communities did not (control group). Focus groups were conducted to examine the views of TMs on their integration into health teams.

RESULTS

Communities with MWHs experienced a significant increase in team births from baseline to post-intervention (10.8% versus 95.2%, P<0.001), with greater TM engagement. Lower rates of maternal and perinatal death were reported from communities with MWHs.

CONCLUSION

The reduction in morbidity and mortality indicates that the establishment of MWHs is an effective strategy to increase the use of SBAs, improve the collaboration between SBAs and TMs, and improve maternal and neonatal health.

A first aid training course for primary health care providers in Nagorno Karabagh: assessing knowledge retention

INTRODUCTION

Conflict in the South Caucasus' Nagorno Karabagh region has damaged health facilities and disrupted the delivery of services and supplies as well as led to depletion of human and fixed capital and weakened the de facto government's ability to provide training for health care providers.

PROBLEM

In response to documented medical training deficits, the American University of Armenia organized a first aid training course (FATC) for primary health care providers within the scope of the USAID-funded Humanitarian Assistance Project in Nagorno Karabagh. This paper reports the follow-up assessments conducted to inform policy makers regarding FATC knowledge and skill retention and the potential need for periodic refresher training.

METHODS

Follow-up assessments were conducted six months and 18 months following the FATC to assess the retention of knowledge, attitudes, and self-reported practices. Eighty-four providers participated in the first follow-up and 210 in the second. The assessment tool contained items addressing the use and quality of the first aid skills, trainee's evaluation of the course, and randomly selected test questions to assess knowledge retention.

RESULTS

At both follow-up points, the participants' assessment of the course was positive. More than 85% of the trainees self-assessed their skills as "excellent" or "good" and noted that skills were frequently practiced. Scores of approximately 58% on knowledge tests at both the first and second follow-ups indicated no knowledge decay between the first and second survey waves, but substantial decline from the immediate post-test assessment in the classroom.

CONCLUSION

The trainees assessed the FATC as effective, and the skills covered as important and well utilized. Knowledge retention was modest, but stable. Refresher courses are necessary to reverse the decay of technical knowledge and to ensure proper application in the field.

Putting people first: a primary health care success in rural India

Background:

The World Health Report, 2008, contains a global review of primary health care on the 30th anniversary of the Declaration of Alma-Ata. The period covered by the study reported on here corresponds with that of the Report, allowing for a comparison of achievements and challenges in one primary health care centre vis-a-vis the WHO standards.

Materials and Methods:

This study uses qualitative and quantitative data from a rural primary care facility in Western Maharashtra, collected over three decades. It analyzes the four groups of reforms defined by WHO in the context of the achievements and challenges of the study facility.

Results:

According to the WHO Report, health systems in developing countries have not responded adequately to people’s needs. However, our in-depth observations revealed substantial progress in several areas, including in family planning, safe deliveries, immunization and health promotion. Satisfaction with services in the study area was high.

Conclusion:

Adequate primary health care is possible, even when all recommended WHO reforms are not fully in place.

Informed consent in international research: the rationale for different approaches

In developed countries, informed consent is based on the autonomy of the individual, a written description of the studies proposed, and previous experience of the participant with Western medicine. Consent is documented by the signature of the participant and supervised by institutional review boards (IRBs), which have conflicts of interest because they are also responsible for limiting institutional liability. In developing countries, the initial decision-making for informed consent is typically vested in the community rather than the individual, and illiteracy is common-limiting the value of written documents and signatures. The challenges in developing countries are exacerbated by the fact that persons at greatest risk of disease are often illiterate, have limited experience with Western medicine, and have limited understanding of the scientific rationale for the studies proposed. Given these differences, it is unrealistic to expect that consent strategies used in developed countries would be effective in such diverse settings.

Management of hypertension at the community level in sub-Saharan Africa (SSA): towards a rational use of available resources

Hypertension is emerging in many developing nations as a leading cause of cardiovascular mortality, morbidity and disability in adults. In sub-Saharan African (SSA) countries it has specificities such as occurring in young and active adults, resulting in severe complications dominated by heart failure and taking place in limited-resource settings in which an individual's access to treatment (affordability) is very limited. Within this context of restrained economic conditions, the greatest gains for SSA in controlling the hypertension epidemic lie in its prevention. Attempts should be made to detect hypertensive patients early before irreversible organ damage becomes apparent, and to provide them with the best possible and affordable non-pharmacological and pharmacological treatment. Therefore, efforts should be made for detection and early management at the community level. In this context, a standardized algorithm of management can help in the rational use of available resources. Although many international and regional guidelines have been published, they cannot apply to SSA settings because the economy of the countries and affordability of the patients do not allow access to advocated treatment. In addition, none of them suggest a clear algorithm of management for limited-resource settings at the community level. In line with available data and analysing existing guidelines, a practical algorithm for management of hypertension at the community level, including treatment affordability, has been suggested in the present work.

The complexity of social mobilization in health communication: top-down and bottom-up experiences in polio eradication

The Polio Eradication Initiative (PEI) has been one of the most ambitious global health efforts in recent times. Social mobilization (SM) has been a strategic component of the PEI. Yet, a close-up analysis of SM dynamics seems to be lacking in the health communication literature. We examine critical aspects of the PEI experience in an attempt to move from dominant informational perspectives to a focus on emerging challenges in polio eradication efforts and new levels of complexity to SM. We examine available literature on communication and public health, available data on SM experiences that support polio eradication in Africa and Asia, and field work conducted by the authors where polio eradication efforts are ongoing. Our analysis suggests that (1) SM should not be casually approached as a top-down informational strategy to advance pre-established health goals; (2) centralized strategies hardly amount to SM; and (3) hybrid options that combine both activist and pragmatic SM are concrete possibilities for global health initiatives. In the context of renewed global democratization and persistent conflicts rooted in ethnicity, religion, and economics, it cannot be assumed that communities will either diligently espouse global goals or necessarily oppose them. Communication and SM strategies should rely on a clear understanding of the motives and agendas of involved actors. Resistance or opposition are important analytical dimensions as they may uncover new opportunities for effective health interventions. Further studies using these perspectives should be a priority for global health programs, including studies of the trust level, or lack thereof, among social actors.

Placing ethics in the centre: negotiating new spaces for ethical research in conflict situations

Issues of power and consent, confidentiality, trust, and benefit, risks to researchers, and potential harm to participants, are all contested when working with different cultures and within environments marked by violence and insecurity. Difficulty resolving these dilemmas may paralyse ethics committees, may fail to give the guidance sought by researchers, and will not help populations who are among the world's most vulnerable. Even where efforts are made to respond to ethical guidelines and to improve practice, considerable impediments are present in many developing countries, including lack of formal ethical review structures in unstable settings, lack of required skills, limited political and institutional recognition of ethical issues, competing interests, and limitations in clinical and research practice (Elsayed 2004, Macklin 2004). In conflict settings, these limitations are more marked, and the responsibilities of the researcher for ethical practice are greater, but the mechanisms for oversight are weaker. Moreover, the constant focus on vulnerabilities and problems, and the often almost total lack of recognition of strengths and resilience, can further disempower already exploited groups and individuals. The capacity of refugees and communities in conflict to take an active role in the research process is seldom acknowledged, and undermines the potential for more innovative research which can help generate the evidence for better policy and practice.

The potential for essential trauma care to empower communities and tackle inequities

In an attempt to address rapidly increasing injuries in low-income and middle-income countries (LMICs), the Essential Trauma Care Project was started with the goal of standardizing trauma care systems. This project, although part of "vertical" essential health services, has the potential to strengthen the health care system as a whole and to empower communities. Improved diagnosis, triage, referral, communication, and transport benefit the integrated health care systems weakened by vertical approaches. This project mobilizes existing resources, including lay people, to establish a "local model of prehospital care," which can raise community capability and foster trust in health systems. This article describes how this project can be an intersection between vertical and horizontal approaches.

'Issues of equity are also issues of rights': lessons from experiences in Southern Africa

BACKGROUND

Human rights approaches to health have been criticized as antithetical to equity, principally because they are seen to prioritise rights of individuals at the expense of the interests of groups, a core tenet of public health. The objective of this study was to identify how human rights approaches can promote health equity.

METHODS

The Network on Equity in Health in Southern Africa undertook an exploration of three regional case studies - antiretroviral access, patient rights charters and civic organization for health. A combination of archival reviews and stakeholder interviews were complemented with a literature review to provide a theoretical framework for the empirical evidence.

RESULTS

Critical success factors for equity are the importance of rights approaches addressing the full spectrum from civil and political, through to socio-economic rights, as well as the need to locate rights in a group context. Human rights approaches succeed in achieving health equity when coupled with community engagement in ways that reinforce community capacity, particularly when strengthening the collective agency of its most vulnerable groups. Additionally, human rights approaches provide opportunities for mobilising resources outside the health sector, and must aim to address the public-private divide at local, national and international levels.

CONCLUSION

Where it is clear that rights approaches are predicated upon understanding the need to prioritize vulnerable groups and where the way rights are operationalised recognizes the role of agency on the part of those most affected in realising their socio-economic rights, human rights approaches appear to offer powerful tools to support social justice and health equity.

Capacity building for epidemiologic research: a case study in the newly independent state of Azerbaijan

PURPOSE

Because many emerging economies lack local capacity for scientific research, capacity building has become a priority for many international development organizations. This article describes and critiques an approach used for building local capacity for applied health research in Azerbaijan, one of the newly independent states (NIS) of the former USSR.

METHODS

In 2000, environmental epidemiology training courses were conducted in Azerbaijan. Several local participants of these courses received hands-on training in the planning and conduct of a subsequent cancer study as a practical extension of the training exercises.

RESULTS

The research demonstrated that international collaboration can not only result in the successful completion of health research in NIS such as Azerbaijan, but also impart research knowledge and experience to local experts. Several practical issues were encountered in the conduct of the training activities that limited their effectiveness. The most desired result (the proposal and conduct of new research by local experts trained through these exercises) has yet to be achieved to the levels expected.

CONCLUSIONS

International collaborations such as the approach described here are useful for imparting expertise to researchers in less affluent countries. However, comprehensive capacity building programs providing ongoing professional development, support, and an enabling environment, rather than scientific training alone, are required to achieve long-term sustainability and measurable outcomes.

Community-based public health interventions in North Korea: one non-governmental organization's experience with tuberculosis and hepatitis B

BACKGROUND

The Democratic People's Republic of Korea, also known as North Korea, is the most isolated country in the world, and has been a source of interest, politically and socially, since the 1953 ceasefire of the Korean War. While in the past year, interest has focused on the nuclear dispute with the USA, over the past decade, most interest has revolved around the economic plight of the country, the lack of funds and resources for health care, and the subsequent public health declines. North Korea's present economic and public health problems began in the early 1990s due to the gradual loss of economic support from its communist allies (i.e. after the fall of the Soviet Union and the capitalization of China), combined with an inordinate number of natural disasters (floods, famine and drought) all occurring within the same time span. These simultaneous events initiated a 'snowball effect' of severe economic depression and a rapid deterioration of the overall public health infrastructure in the country. North Korea's continued isolation and reluctance to release health statistics has left the international community uncertain of the precise extent of the public health devastation. The uncertainty of the situation has been further complicated by disparate accounts of the public health declines. For instance, the North Korean Government has estimated that approximately 220,000 people died due to famine in the 1990s, while the World Health Organization (WHO) claims that this figure is closer to 2 million. In the past few years, the willingness of the North Korean Government to engage the outside world has increased. This is reflected by the growing number of foreign aid organizations or non-governmental organizations (NGOs) that have been permitted entry into the country. NGOs have not only served to improve various aspects of the public health system but also serve as a source of 'on-the-ground' information for the outside world. This role has proven critical not only for public health purposes but for facilitating improved international relations between countries.

Preparing for international medical service

In many ways, preparation for medical service outside the United States is not greatly different from preparation for a self-guided vacation tour of another country. The major differences are in the rigor that one should apply to being sure all details are set, particularly if one is planning to go to a site away from a capital city. Additionally, the mental preparation is required in terms of the understanding of global health issues in a holistic sense and the personal mental preparation for working under what may be austere conditions. With solid preparation, anyone interested in IH experiences should be able to have a rewarding, trouble-free experience.

Informed choices for attaining the Millennium Development Goals: towards an international cooperative agenda for health-systems research

Health systems constraints are impeding the implementation of major global initiatives for health and the attainment of the Millennium Development Goals (MDGs). Research could contribute to overcoming these barriers. An independent task force has been convened by WHO to suggest areas where international collaborative research could help to generate the knowledge necessary to improve health systems. Suggested topics encompass financial and human resources, organisation and delivery of health services, governance, stewardship, knowledge management, and global influences. These topics should be viewed as tentative suggestions that form a basis for further discussion. This article is part of a wide-ranging consultation and comment is invited. The potential agenda will be presented at the Ministerial Summit on Health Research in November, 2004, and revised in the light of responses. Subsequently, we hope that resources will be committed to generate the evidence needed to build the equitable, effective, and efficient health systems needed to achieve the MDGs

Gender stratification in management. The World Health Organization 2000

The World Health Organization (WHO) is a global organization that nowadays has integrated gender issues into its policy, programmes and budget. How then is the state of affairs in the area of gender equity at the ultimate governing bodies of the modern WHO? This study aims to assess the representation of women and men and their promotion within the supreme decision-making bodies of the WHO during the year 2000. Information sources used are the official and confirmed protocols of the 53rd World Health Assembly (WHA) in 2000 and of the two Executive Board (EB) meetings of the corresponding year. A descriptive quantitative content analysis approach is used exclusively. The present study demonstrates strikingly skewed gender distribution, with men substantially at an advantage numerically in the prominent positions at the WHA 2000. Additionally, men also hold an advantage in terms of being promoted to leading positions within the bodies examined, notably all upgraded chairs of the EB during 2000. However, the formerly male-dominated supervisory positions of the WHO are, these days, challenged by women having been elected at the very top of the WHO. The present study stresses the need to elaborate a qualitative research design to advance the understanding of the social construction of gender in supreme governing positions of the modern WHO.

Antibiotic treatment for bacterial meningitis in children in developing countries

Bacterial meningitis causes 125,000 deaths each year in infants and young children and 96% of these occur in less developed countries where up to 50% of children with this disease die and 25-50% of survivors have neurological sequelae. Although 3rd-generation cephalosporins are optimal empirical therapy for bacterial meningitis, they are unaffordable in many developing countries. The majority of children worldwide are currently treated with cheaper alternatives. This paper reviews the challenges facing clinicians treating bacterial meningitis in developing countries, highlighting the problem of changing patterns of antibiotic resistance. In particular, it details the evidence for the use of chloramphenicol and 3rd-generation cephalosporins.

Infectious diseases, non-zero-sum thinking, and the developing world

Despite some improvements in the health status of the world during the last few decades, major obstacles remain. Improvements in health outcomes have not been shared equally among countries and poverty is clearly the main reason. Infectious diseases, which remain the major cause of death worldwide, are an incalculable source of human misery and economic loss. In fact, 25% of all deaths and 30% of the global burden of disease are attributed to infectious diseases. Unfortunately, more than 95% of these deaths, most of which are preventable, occur in the developing world, where poverty is widespread. The 3 major infectious disease killers in these countries are HIV/AIDS, tuberculosis, and malaria. The principles of social justice and health as a human right in the developing world have been advocated as the main justification for health assistance from rich to poor countries. Although we do not disagree with this, we argue that a strategy that emphasizes the shared benefit to rich and poor countries would facilitate this process. We propose that the accomplishment of these challenging tasks should be viewed from the perspective of game theory, where the interests of the parties (in this case rich and poor countries) overlap. As the world becomes increasingly integrated, economic development in resource-poor countries will increase the opportunities for richer countries to profit from investment in the developing world. Global health has political and international security implications for the developed world, as well. In view of the current health status of the developing world, we are not playing a game but facing a matter of life and death. "When health is absent, wisdom cannot reveal itself, art cannot become manifest, strength cannot fight, wealth becomes useless, and intelligence cannot be applied" --Herophilus, 325 BCE (Physician to Alexander the Great). The purpose of this article is to address the relationship between health, poverty, and development in the context of game theory. We will focus on the link between economic inequalities and health outcomes, exclusively concentrating our analysis on the impact of infectious diseases. Subsequently, we will outline the game, the players, and the potential win-win outcomes that may potentially result.

Rural health around the world: challenges and solutions

Despite the huge differences between developing and developed countries, access is the major issue in rural health around the world. Even in the countries where the majority of the population lives in rural areas, the resources are concentrated in the cities. All countries have difficulties with transport and communication, and they all face the challenge of shortages of doctors and other health professionals in rural and remote areas. Many rural people are caught in the poverty- ill health-low productivity downward spiral, particularly in developing countries. Since 1992, WONCA, the World Organization of Family Doctors, has developed a specific focus on rural health through the WONCA Working Party on Rural Practice. This Working Party has drawn national and international attention to major rural health issues through World Rural Health Conferences and WONCA Rural Policies. The World Health Organization (WHO) has broadened its focus beyond public health to partnership with family practice, initially through a landmark WHO-WONCA Invitational Conference in Canada. From this has developed the Memorandum of Agreement between WONCA and WHO which emphasizes the important role of family practitioners in primary health care and also includes the Rural Health Initiative. In April 2002, WHO and WONCA held a major WHO-WONCA Invitational Conference on Rural Health. This conference addressed the immense challenges for improving the health of people of rural and remote areas of the world and initiated a specific action plan: The Global Initiative on Rural Health. The "Health for All" vision for rural people is more likely to be achieved through joint concerted efforts of international and national bodies working together with doctors, nurses and other health workers in rural areas around the world.

Broadening participation in community problem solving: a multidisciplinary model to support collaborative practice and research

Over the last 40 years, thousands of communities-in the United States and internationally-have been working to broaden the involvement of people and organizations in addressing community-level problems related to health and other areas. Yet, in spite of this experience, many communities are having substantial difficulty achieving their collaborative objective, and many funders of community partnerships and participation initiatives are looking for ways to get more out of their investment. One of the reasons we are in this predicament is that the practitioners and researchers who are interested in community collaboration come from a variety of contexts, initiatives, and academic disciplines, and few of them have integrated their work with experiences or literatures beyond their own domain. In this article, we seek to overcome some of this fragmentation of effort by presenting a multidisciplinary model that lays out the pathways by which broadly participatory processes lead to more effective community problem solving and to improvements in community health. The model, which builds on a broad array of practical experience as well as conceptual and empirical work in multiple fields, is an outgrowth of a joint-learning work group that was organized to support nine communities in the Turning Point initiative. Following a detailed explication of the model, the article focuses on the implications of the model for research, practice, and policy. It describes how the model can help researchers answer the fundamental effectiveness and "how-to" questions related to community collaboration. In addition, the article explores differences between the model and current practice, suggesting strategies that can help the participants in, and funders of, community collaborations strengthen their efforts.

Ethical oversight of public health research: can rules and IRBs make a difference in developing countries?

Controversies in the conduct of international research continue to pose challenges for the system of ethical review, particularly for developing countries. Although the concept of vulnerability is key to addressing these challenges, ethical review has typically ignored the agency of vulnerable participants and groups in determining what kind of review process is needed. Concurrent with developments shaping the new public health that seek to operationalize empowerment of communities by placing them as initiators and organizers of their own health, ethical review of public health research must find ways to recognize the agency of vulnerable individuals, groups, and communities in the review process if it is to address effectively the ethical dilemmas currently evident in collaborative international research.

Nutritional consequences of the African diaspora

Along with their foods and dietary customs, Africans were carried into diaspora throughout the Americas as a result of the European slave trade. Their descendants represent populations at varying stages of the nutrition transition. West Africans are in the early stage, where undernutrition and nutrient deficiencies are prevalent. Many Caribbean populations represent the middle stages, with undernutrition and obesity coexisting. African-Americans and black populations in the United Kingdom suffer from the consequences of caloric excess and diets high in fat and animal products. Obesity, non-insulin-dependent diabetes mellitus, hypertension, coronary heart disease, and certain cancers all follow an east-to-west gradient of increasing prevalence. Public health efforts must focus not only on eradicating undernutrition in West Africa and the Caribbean but also on preventing obesity, hypercholesterolemia, and their consequences. Fortunately, a coherent and well-supported set of recommendations exists to promote better nutrition. Implementation of it founders primarily as a result of the influence of commercial and political interests.
