Implementation of the DOTS strategy for tuberculosis control in rural Kiboga District, Uganda, offering patients the option of treatment supervision in the community, 1998-1999.

SETTING: Kiboga District, a rural district in central Uganda. OBJECTIVE: As part of routine tuberculosis control programme operations, to measure the effectiveness and acceptability of community-based tuberculosis (TB) care using the directly observed treatment, short-course (DOTS) strategy for TB control. The implementation of the DOTS strategy with active participation of local communities in providing the option of treatment supervision in the community is known in Uganda as community-based DOTS (CB-DOTS). DESIGN: Effectiveness was measured by comparing TB case-finding and treatment outcomes before and after the introduction of CB-DOTS in 1998. Acceptability was measured by administering a knowledge, attitudes and beliefs questionnaire to community members, health care workers and TB patients before and after the intervention. RESULTS: A total of 540 TB patients were registered in the control period (1995-1997) before the introduction of CB-DOTS, and 450 were registered in the intervention period (1998-1999) after the implementation of CB-DOTS. Following the implementation of CB-DOTS, treatment success among new smear-positive pulmonary TB cases increased from 56% to 74% (RR 1.3, 95%CI 1.2-1.5, P < 0.001) and treatment interruption decreased from 23% to 1% (RR 16.5, 95%CI 6.1-44.7, P < 0.001). There was no significant difference in the proportion of deaths before and after the implementation of CB-DOTS (15% vs. 14% for new smear-positive pulmonary, and 38% vs. 29% for new smear-negative and extra-pulmonary TB cases). The acceptability of CB-DOTS was very high among those interviewed, mainly because CB-DOTS improved access to TB care, decreased costs and enabled patients to stay with their families. CONCLUSIONS: In enabling patients to choose TB treatment supervision in the community, CB-DOTS provided a highly effective and acceptable additional option to conventional TB care. Efforts are underway to address the high case fatality rates in both study groups before and after the introduction of CB-DOTS. CB-DOTS is an example of shared responsibility between health services and communities in tackling a major public health priority.

Awareness and misconception of hypertension in Canada: results of a national survey.

BACKGROUND: The Canadian Heart Health Surveys were the last Canadian population-based physical measures surveys (conducted between 1988 and 1992) that determined that hypertension in Canada was poorly managed. Hypertension was undetected in almost one-half of all hypertensive Canadians surveyed, and only 13% of those with hypertension were treated and controlled to recommended blood pressure targets. The reasons for poor control are likely multifactorial; however, a lack of public awareness and understanding of hypertension may contribute to the epidemic of uncontrolled hypertension in Canada. METHODS: A national telephone survey was conducted comprising 1001 randomly selected men and women older than 40 years of age to determine the level of public awareness, understanding and misconception of hypertension in Canada. The survey was balanced for region, age and sex. RESULTS: Thirty-four per cent of respondents had been diagnosed with high blood pressure or hypertension by a health care professional, but only 58% of respondents had ever discussed their blood pressure with a physician, and only 44% were able to identify their own blood pressure or differentiate blood pressure levels considered to be above or below recommended targets. Overall, respondents had a poor understanding of the consequences of high blood pressure or hypertension. The majority were unaware of the association between hypertension and heart disease (80%), heart attack (66%), kidney disease (98%), damage to blood vessels (95%) and premature death (74%). Respondents also had limited knowledge of lifestyle issues affecting hypertension, despite 44% indicating that they were overweight and 18% identifying themselves as smokers. Almost two-thirds (63%) thought hypertension had clearly identifiable signs or symptoms, although they believed that hypertension was not a serious medical condition. Most respondents (59%) falsely believed that they would not develop hypertension and 38% thought that they would be able to control hypertension without the aid of a physician if they did have hypertension. CONCLUSIONS: While hypertension-related complications are preventable, lack of public awareness and misconceptions about hypertension and hypertensive complications are common and may, in part, be associated with ongoing inadequate Canadian awareness, treatment and control rates for hypertension. Increasing public awareness of hypertension using public education and health provider strategies should be a high national health priority.

An evaluation of tobacco brief intervention training in three indigenous health care settings in north Queensland.

OBJECTIVE: To evaluate the pilot phase of a tobacco brief intervention program in three Indigenous health care settings in rural and remote north Queensland. METHODS: A combination of in-depth interviews with health staff and managers and focus groups with health staff and consumers. RESULTS: The tobacco brief intervention initiative resulted in changes in clinical practice among health care workers in all three sites. Although health workers had reported routinely raising the issue of smoking in a variety of settings prior to the intervention, the training provided them with an additional opportunity to become more aware of new approaches to smoking cessation. Indigenous health workers in particular reported that their own attempts to give up smoking following the training had given them confidence and empathy in offering smoking cessation advice. However, the study found no evidence that anybody had actually given up smoking at six months following the intervention. Integration of brief intervention into routine clinical practice was constrained by organisational, interpersonal and other factors in the broader socioenvironmental context. CONCLUSIONS/IMPLICATIONS: While modest health gains may be possible through brief intervention, the potential effectiveness in Indigenous settings will be limited in the absence of broader strategies aimed at tackling community-identified health priorities such as alcohol misuse, violence, employment and education. Tobacco and other forms of lifestyle brief intervention need to be part of multi-level health strategies. Training in tobacco brief intervention should address both the Indigenous context and the needs of Indigenous health care workers.

The behavioral determinants of exercise: implications for physical activity interventions.

In light of the well-documented health benefits of physical activity and the fact that the majority of adult men and women are inactive, promoting regular physical activity is a public health priority. This chapter reviews current research findings regarding the determinants of exercise behavior. It also discusses the implications of this knowledge for individual and public health recommendations and intervention strategies for promoting physical activity. The discussion is predicated on the belief that physical activity is a complex, dynamic process. During their lives, individuals typically move through various phases of exercise participation that are determined by diverse factors. This chapter discusses physical activity determinants in two broad categories: individual characteristics, including motivations, self-efficacy, exercise history, skills, and other health behaviors; and environmental characteristics such as access, cost, and time barriers and social and cultural supports.

Modifying and developing health behavior.

The literatures on both behavior modification and behavioral development have engendered innovations in public health programs, addressing problems of patient adherance to preventive and therapeutic regimens, delay in seeking diagnosis of illness symptoms, risk-taking behavior, and other aspects of lifestyle associated with health. Because most of this literature derives from psychology, there has been a distinct bias in the construction of interventions, pointing them directly at individuals, usually in a counseling or small group mode of delivery. These developments served public health well enough during a decade or so when the preoccupation was with utilization of health services and medical management of chronic diseases. With the publication of the Lalonde Report in Canada in 1974, the passage of Public Law 94-317 in 1976 in the United States, and similar initiatives in other English-speaking and European countries, the recognition of the greater complexities of lifestyle development and modification in the absence of symptoms has taken hold. Policy makers and public health workers seek a more efficient and equitable set of strategies to meet the behavioral health challenges of modern society without placing the entire weight of responsibility for behavior on the individual or on therapeutic practitioners. Concurrently, on a more global scale and in the developing countries, a concern has emerged for strategies that give individuals, families, and communities a greater role in deciding their own health priorities. The convergence of these two trends--one seeking to distribute responsibility for lifestyle more equitably and the other seeking to distribute responsibility for planning health programs more equitably --calls for policies, strategies, and interventions that will place similar emphasis on health education and organizational, economic, and environmental supports for health behavior. The combination of these elements of support for behavior calls, in turn, for research and more inventive applications of theory from sociology, political science, economics, and anthropology. Public health workers will need to become more conversant and facile in these social sciences, as they have in psychology and its applications in the recent past.

Screening for colorectal cancer, 1996.

Screening average-risk people aged 55 to 70 years for colorectal cancer is now a public health priority in Australia. Pilot studies of faecal occult blood testing are required to find ways of achieving optimal compliance and cost efficiency in the Australian health care setting. Flexible sigmoidoscopy probably should be used as complementary screening but further trials are needed. High-risk groups (family history of colorectal cancer, or previous ulcerative colitis, adenomas or cancer) should already be in surveillance programs.

[Prevalence of malnutrition in the Mbao Health District].

Protein-energy malnutrition is a real health priority in developing countries specially in african ones. So, a cross-sectional study was conducted, from April 14 to July 28 1995, in the health district of Mbao in Senegal, to determine the prevalence of protein-energy malnutrition (PEM) in a population of children 0-5 year old utilizing the health center, for a curative care, an immunization, a growth monitoring. Anthropometric and sociodemographic data were collected and analysed using a microcomputer with WHO/CDC Epi Info 6.0. The index weight/age expressed on Zscore was used with comparison to NCHS/CDC/WHO population's international reference. Among 204 children, 89 (43.6%) present a PEM.51 (57.3%) are male. More than 60% of the children with PEM are 6-29 months old. 74 (83.2%) live in the surroundings of Mbao. They all come from different ethnic group. 67.4% utilize the health center for a curative care and 7.9% for growth monitoring. There is no relation statistically significant between protein-energy malnutrition and the parameters we studied. To overcome such problem, it is necessary to strengthen the management of malnourished children in specialized centers, to educate families in the nutritional properties of local products and to improve the socioeconomic status of the population for better access to these products.

Identification and priority setting for health technology assessment in The Netherlands: actors and activities.

This article describes the actual situation at the beginning of 1999 with regard to identification and priority setting for health technology assessment (HTA) on a national level in the Netherlands. For this purpose the literature on HTA published in 1980-1998, mainly national, was thoroughly reviewed. Many policy documents and other reports from the 'grey literature' of identification and priority setting for HTA in the Netherlands were also used. The results show that attempts to identify and set priorities for HTA is a new activity in the Netherlands. The three most important actors in the field are the Health Council, the Council for Health Research and the Health Insurance Council. Methodologies differ depending on the content and scope of each programme. In addition, the methods used are not always transparent and the activities are not co-ordinated. The lack of co-ordination is due to the fact that there is no single organisation that is authorized to identify and set priorities for HTA. Suggestions for improving co-ordination are proposed with the aim of developing a truly national effort in this field, which will enable a more balanced and efficient set of HTA activities.

[European public health professionals express ten priorities for the European Union...to be followed].

Even if the European Union acquired explicit competencies in public health with the Maastricht and Amsterdam Treaties (articles 129 and 152), public health professionals still have not had their word in the definition of public health priorities. Yet it is they, whatever their mission, who must take into consideration the new constraints imposed by Community directives. The French Society for Public Health (FSPH) took the initiative of running a project, financed by the European Commission, aiming to shed light on some of the public health problems considered priority in the 15 member states, and to provide suggestions for facing them. The FSPH adopted a resolutely participative and pragmatic process. At each step (definition of priorities and compiling arguments), the intention of the SFPH was more to allow different, even diverging, points of view to be expressed, than to aim for a hypothetical representativeness. The undertaken themes are the social gradients in health, alcohol, illicit drugs, tobacco, surveillance of health issues, quality of care, older persons, mental health, the environment, nutrition and food security. This work marks the wish of the FSPH for international openness toward Europe. The FSPH hopes that this work becomes a platform for the development of a reinforced dialogue between public health professionals and European decision makers.

Home health care nursing research priorities.

The purpose of this study was to determine research priorities for home health care nursing. A Delphi study was undertaken to generate and prioritize research topics. The first round consisted of members of the Home Health Nurses Association Research Committee (n = 27); subsequent rounds also included nurse researchers who had conducted research in home health care (n = 17). Consensus emerged after three rounds, with the four most important priorities identified as outcomes, health policy, the use of advanced practice nurses, and models of care/best practice. These areas are consistent with the regulatory events in home health care in the last 10 years.

Pediatric surgery in sub-Saharan Africa.

Pediatric surgery in sub-Saharan Africa is disadvantaged by the large number of sick children, disease patterns specific to the region, late presentation, and advanced pathology. In addition, it is practiced in an environment of limited resources and facilities and other health priorities. Obstacles to better pediatric-surgical care (PSC) include a general lack of interest in surgical conditions affecting African children, its poorly defined role, and a lack of political commitment by governments and international agencies to see surgical care of children improve. Pediatric-surgical practice in Africa must be cognizant of the factors that limit delivery of surgical services and work toward developing cost-effective strategies that benefit the largest number of children. Demonstrating that childhood surgical conditions are a significant public health-care problem is the most likely way to change health-care policy and to ensure adequate resources for PSC. Other priorities should be to define a cost-effective package of pediatric surgical services, improve PSC at the community level, and strengthen pediatric surgical-education.

[Community health policy as a research area in public health and social sciences].

The community plays a central role in new public health concepts. However, local health policy has not achieved a central role in cities and counties. Therefore it seems to be both reasonable and necessary for social sciences to analyse the health options in local politics and to identify aspects for improvement. The implementation of health priorities and their realisation at the local level, the latter with regard to supporting (positive) and hampering (negative) factors, and the development of strategies to implement health programmes are suggested as main research topics. Starting from the assumption that complex organisational processes in communities need organisational support, the role of the public health service as coordinating and initialising factor for the alteration of community health programmes should be investigated more thoroughly. The public health service as a part of the administration in municipalities is also involved in the endeavour to modernize administration. A main area for research will be how far the knowledge about participation of citizens and new management theories support health as a task of local politics.

Community Health Planning↗

[Patients and clients integrated in the process of constructing the regional health organisation plans].

The government orders of April 1996 were devoted to the second generation Regional Health Organisation Plans (SROS II) as health planning levers. One of the main issues at stake in their development was the need to favour an overall management of the regional public health priorities and to involve the system's clients in them. In order to better understand the opinions of the clients themselves and the opinions of the health planning professionals on the participation of the clients in SROS II, a national sample was selected in order to take into account the diversity of regional experiences, the different institutional linkages and the unity of both the place and the problem at hand. Two series of 42 interviews conducted at 6 month intervals were recorded and a thematic analysis according to a validated interview grid was carried out by the Analytical Laboratory for Social and Health Policy (LAPSS) at the National School of Public Health (ENSP). This survey shows that the first attempt to include the participation of the system's clients in the health planning efforts by the SROS II was appreciated and recognised as legitimate and useful, yet suffered from a lack of legibility and of a clear definition of its role. Other participation mechanisms remain to be investigated and explored as they could be enlarged in the next plan, in which the clients could become a separate entity of actors as an entirely independent group.
