Narrowing the gap between academic professional wisdom and community lay knowledge: perceptions from partnerships.

Community involvement in health through community partnerships (CPs) has been widely advocated. Putting CPs into practice is complex and represents a challenge for all the stakeholders involved in the change process. Employing data from five CPs aiming to bring together communities, academics and health service providers in South Africa, this paper aims to examine and compare the views of the health care professionals with those of the community members with respect to each other's skills and abilities. Five domains of expertise in partnership working are examined: educational competencies; partnership fostering skills; community involvement expertise; change agents proficiencies; and strategic and management capacities. The findings suggest that the community recognizes the expertise and abilities brought by the professional staff to the CPs. Community members have a positive view of the capabilities of the professionals, in particular their abilities as resource persons in the areas of budget management, policy formulation and the introduction and management of change. The professionals, on the other hand, are cautious regarding the level of skill and capability in communities. The limited appreciation of community skills by the professionals covered all the five domains of expertise examined. The findings suggest that if joint working is to survive, the professionals will need to increase their valuation of the indigenous proficiencies inherent in their community partners. We conclude that programme models need to consciously incorporate in their design and implementation, capacity building, skills transfer and empowerment strategies.

Health system reform and the role of field sites based upon demographic and health surveillance.

Field sites for demographic and health surveillance have made well-recognized contributions to the evaluation of new or untested interventions, largely through efficacy trials involving new technologies or the delivery of selected services, e.g. vaccines, oral rehydration therapy and alternative contraceptive methods. Their role in health system reform, whether national or international, has, however, proved considerably more limited. The present article explores the characteristics and defining features of such field sites in low-income and middle-income countries and argues that many currently active sites have a largely untapped potential for contributing substantially to national and subnational health development. Since the populations covered by these sites often correspond with the boundaries of districts or subdistricts, the strategic use of information generated by demographic surveillance can inform the decentralization efforts of national and provincial health authorities. Among the areas of particular importance are the following: making population-based information available and providing an information resource; evaluating programmes and interventions; and developing applications to policy and practice. The question is posed as to whether their potential contribution to health system reform justifies arguing for adaptations to these field sites and expanded investment in them.

An evaluation of sensitivity and specificity of blood alcohol concentrations obtained by a breathalyser survey in a casualty department in Kenya.

Whereas breathalysers have been shown to provide blood alcohol concentration (BAC) measurements comparable to those obtained by gas chromatography, such evidence has not been reported in low and middle income countries where measures for preventing alcohol-related injuries are virtually non-existent. Before promoting any method of blood alcohol evaluation, as a routine procedure for monitoring the association of alcohol with different types of injuries in Kenya, we sought to assess the reliability and validity of blood alcohol results obtained by a breathalyser, using gas chromatography analysis values as the reference, in a sample of 179 trauma-affected adults presenting to casualty departments. No differences in proportions of subjects with high levels of blood alcohol (equal to or greater than 50 mg%) were detected by breath and blood test procedures (58.7 vs 60.3%). Breathalyser readings yielded high levels of sensitivity and specificity (97.2 and 100%, respectively) with optimal positive and negative predictive values (100 and 95.9%, respectively) at higher BACs (> or = 50 mg%). The study thus reaffirms that breathalyser tests are of value in detecting high blood alcohol levels and can be used to rapidly identify intoxicated subjects. The procedure is easy to perform and can be used for monitoring the association between blood alcohol level and driving in low-income developing countries.

The emerging international policy agenda for reproductive health services in conflict settings.

Over the past 20 years, shifts in the nature of conflict and the sheer numbers of civilians affected have given rise to increasing concern about providing appropriate health services in unstable settings. Concurrently, international health policy attention has focused on sexual and reproductive health issues and finding effective methods of addressing them. This article reviews the background to the promotion and development of reproductive health services for conflict-affected populations. It employs qualitative methods to analyse the development of policy at international level. First we examine the extent to which reproductive health is on the policy agendas of organisations active in humanitarian contexts. We then discuss why and how this has come about, and whether the issue has sufficient support to ensure effective implementation. Our findings demonstrate that reproductive health is clearly on the agenda for agencies working in these settings, as measured by a range of established criteria including the amount of new resources being attracted to this area and the number of meetings and publications devoted to this issue. There are, however, barriers to the full and effective implementation of reproductive health services. These barriers include the hesitation of some field-workers to prioritise reproductive health and the number and diversity of the organisations involved in implementation. The reasons for these barriers are discussed in order to highlight areas for action before effective reproductive health service provision to these populations can be ensured.

Rehabilitating health services in Cambodia: the challenge of coordination in chronic political emergencies.

The end of the Cold War brought with it opportunities to resolve a number of conflicts around the world, including those in Angola, Cambodia, El Salvador and Mozambique. International political efforts to negotiate peace in these countries were accompanied by significant aid programmes ostensibly designed to redress the worst effects of conflict and to contribute to the consolidation of peace. Such periods of political transition, and associated aid inflows, constitute an opportunity to improve health services in countries whose health indicators have been among the worst in the world and where access to basic health services is significantly diminished by war. This paper analyzes the particular constraints to effective coordination of health sector aid in situations of 'post'-conflict transition. These include: the uncertain legitimacy and competence of state structures; donor choice of implementing channels; and actions by national and international political actors which served to undermine coordination mechanisms in order to further their respective agendas. These obstacles hindered efforts by health professionals to establish an effective coordination regime, for example, through NGO mapping and the establishment of aid coordinating committees at national and provincial levels. These technical measures were unable to address the basic constitutional question of who had the authority to determine the distribution of scarce resources during a period of transition in political authority. The peculiar difficulties of establishing effective coordination mechanisms are important to address if the long-term effectiveness of rehabilitation aid is to be enhanced.

Violence against children and adolescents. International perspectives.

Selected topics of violence against children and adolescents that occur in countries outside of the United States are discussed. Focus is given to middle-income and low-income countries and emphasis is placed on the epidemiology of this pressing public health problem, particularly on conditions that are peculiar to children and adolescents in international settings, such as female genital mutilations, wars, displacements, and land mines. The discussion of child maltreatment is presented in the context of child rearing and discipline in different cultures. Recommendations for action and violence prevention are offered in the light of vast cultural differences.

Injury control in Africa: getting governments to do more.

Despite increasing recognition of injury as a major public health problem worldwide, it has received limited attention and resources. This lack of attention is most notable in low-income countries. As part of efforts to develop coordinated injury control activities in Africa, a round table session was held at the Third International Conference on Injury Prevention and Control in Melbourne, Australia. The aims of the forum were to provide injury control researchers from Africa the opportunity to come together and reflect on issues of injury control in Africa, to deliberate on strategies of getting African governments to show more interest in injury control, and to solicit more assistance from the international donor community Participants from Ghana, Kenya, South Africa and Zimbabwe presented the magnitude of the injury burden in their respective countries, reflected on current research efforts and highlighted the preventive efforts being undertaken. The forum made many recommendations including several regarding specific actions required of African governments, individual researchers and donor agencies.

Women, health and humanitarian aid in conflict.

The burden of political conflict on civilian populations has increased significantly over the last few decades. Increasingly, the provision of resources and services to these populations is coming under scrutiny; we highlight here the limited attention to gender in their provision. Women and men have different exposures to situations that affect health and access to health-care and have differential power to influence decisions regarding the provision of health services. We argue that the role of women in planning is central to the provision of effective, efficient and sensitive health-care to conflict-affected populations.

Drinking and driving in an urban setting in Kenya.

A roadside alcohol prevalence survey of drivers randomly selected from the general traffic was conducted in Eldoret, Kenya. Blood alcohol concentration (BAC) data obtained by a breath test in 90% of the sample (n = 479) was analysed by demographic and travel characteristics. 19.9% had a positive breath test (BAC > or = 5 mg%), 8.4% had BACs greater than 50 mg%, and 4% exceeded 80 mg%. A greater proportion of males (20%) had been drinking compared to females (12.5%): all drivers with high BACs (> or = 50 mg%) were males. The likelihood of having consumed alcohol was greater in motorists aged 25 years and above (20.4%) than in younger drivers aged 16-24 years (15.4%), their mean BACs were also more elevated (57 mg% versus 31 mg%). In comparison to operators of public service vehicles (PSV), people driving personal cars were more than twice as likely to have been drinking: with 21.9% being BAC positive against 10.8% (OR = 2.3; 95% CI, 1.0 to 6.3, p = 0.05). Educated individuals with skilled careers tended to indulge in drink-driving to a greater extent than professional drivers (operators of public transport, taxi and heavy goods vehicles), with BAC prevalence rates of 23.7% and 15.5%, respectively. Other circumstances influencing the probability of drink-driving were number of vehicle occupants, distance to destination, road location, time of the night and whether it was a weekend or weekday. These findings are discussed in relation to the potential for promotion of relevant deterrent measures, including the establishment of an appropriate BAC legal limit for drivers in Kenya.

A triple burden for health sector reform: 'post'-conflict rehabilitation in Uganda.

While conflict continues to threaten health development in many countries, relative peace has been secured in others. The transition from war to peace carries important political and economic opportunities for the reappraisal of social policy in general, and of health policy in particular. The health systems of countries recovering from prolonged periods of conflict often carry a double burden: the inheritance of an inappropriate and unaffordable health system developed in the pre-conflict era, and the particular, long-term effects of conflict on health and health services. This paper reports on the particular policies designed to rehabilitate the Ugandan health system, and argues that they exacerbated, rather than alleviated, the health crisis inherited in 1986. In this way they posed a third burden. By analyzing the context and process of policy formulation in the immediate post-conflict period, it explores the rationale which lay behind the adoption of these policies and identifies potential strategies for strengthening policy development in these unstable, resource-poor and health-deprived situations.

Differences in public and private health services in a rural district of Malaysia.

A cross-sectional study, comparing the nature of services in 15 private clinics and 6 public health facilities, was undertaken in a rural district of Malaysia. Semi-structured interviews and observations using check-lists were employed. Public health facilities were run by younger doctors (mean age = 31.1 years), supported mostly by trained staff. The private clinics were run by older doctors (mean age = 41.2 years) who had served the district for much longer (8.9 years vs 1.5 years) but were supported by less well trained staff. The curative services were the main strength of the private clinics but their provision of preventive care was less comprehensive and of inferior quality. Private clinics were inclined to provide more expensive diagnostic services than the public facilities. 'Short hours' private clinics had very restricted opening hours and offered limited range of services.
