Perinatal mortality in Matlab, Bangladesh: a community-based study

Perinatal deaths, comprising stillbirths and deaths during the first week of life, were monitored over the eight-year period 1979 to 1986 in a rural Bangladeshi population of 196,000. The perinatal mortality rate was 75 per 1000 total births. The rate was 13% higher in males than females. Stillbirth and early neonatal mortality rates were 37 and 38 per 1000 total births, respectively. The major causes of perinatal deaths are presented, as well as some of the maternal determinants. During the period under study, perinatal mortality declined regularly and significantly over time in an area covered by an intensive Family Planning and Health Services programme, but not in the adjacent control area. This raises the issue of the impact of such a programme upon perinatal mortality, and the need to include a strong maternity care component into primary healthcare strategies if further reductions of perinatal mortality are to be achieved.     

Planning and implementing a community-based public health advocacy campaign: a transport case study from Australia

Facilitating community action is a key goal of health promotion. This paper describes a public health advocacy framework. It then presents a case study of its application for planning community action by a community alliance concerned about increased heavy traffic on roads through a small regional city in the South West region of Western Australia. The case study illustrates defining the public health problem, the solution and the target for action; and the implementation of a comprehensive range of strategies including a media advocacy strategy to attract public attention, to reframe media messages, and to provide a policy alternative to government and industry. The campaign was evaluated in terms of process and outcomes, and was successful in putting pressure on key stakeholders and achieving the alliance's two main goals. The case study demonstrates the value of a well-planned campaign and including public health advocacy in public health practice, as an important strategy to facilitate the creation of healthy environments through healthy public policy.     

Local-level mortality surveillance in resource-limited settings: a case study of Cape Town highlights disparities in health

Objective

To identify the leading causes of mortality and premature mortality in Cape Town, South Africa, and its subdistricts, and to compare levels of mortality between subdistricts.

Methods

Cape Town mortality data for the period 2001–2006 were analysed by age, cause of death and sex. Cause-of-death codes were aggregated into three main cause groups: (i) pre-transitional causes (e.g. communicable diseases, maternal causes, perinatal conditions and nutritional deficiencies), (ii) noncommunicable diseases and (iii) injuries. Premature mortality was calculated in years of life lost (YLLs). Population estimates for the Cape Town Metro district were used to calculate age-specific rates per 100 000 population, which were then age-standardized and compared across subdistricts.

Findings

The pattern of mortality in Cape Town reflects the quadruple burden of disease observed in the national cause-of-death profile, with HIV/AIDS, other infectious diseases, injuries and noncommunicable diseases all accounting for a significant proportion of deaths. HIV/AIDS has replaced homicide as the leading cause of death. HIV/AIDS, homicide, tuberculosis and road traffic injuries accounted for 44% of all premature mortality. Khayelitsha, the poorest subdistrict, had the highest levels of mortality for all main cause groups.

Conclusion

Local mortality surveillance highlights the differential needs of the population of Cape Town and provides a wealth of data to inform planning and implementation of targeted interventions. Multisectoral interventions will be required to reduce the burden of disease.     

The rationale for integrated childhood meningoencephalitis surveillance: a case study from Cambodia

Problem

Recent progress in vaccine availability and affordability has raised prospects for reducing death and disability from neurological infections in children. In many Asian countries, however, the epidemiology and public health burden of neurological diseases such as Japanese encephalitis and bacterial meningitis are poorly understood.

Approach

A sentinel surveillance system for Japanese encephalitis was developed and embedded within the routine meningoencephalitis syndromic surveillance system in Cambodia in 2006. The sentinel surveillance system was designed so surveillance and laboratory testing for other etiologies of neurological infection could be incorporated.

Local setting

The Communicable Disease Control department of the Ministry of Health in Cambodia worked with partners to establish the sentinel surveillance system.

Relevant changes

The sentinel surveillance system has provided important information on the disease burden of Japanese encephalitis in Cambodia and is now providing a platform for expansion to incorporate laboratory testing for other vaccine-preventable neurological infections in children.

Lessons learned

Sentinel surveillance systems, when linked to syndromic reporting systems, can characterize the epidemiology of meningoencephalitis and identify the proportion of hospital-based neurological infection in children that is vaccine preventable. Integrated systems enable consistency in data collection, analysis and information dissemination, and they enhance the capacity of public health managers to provide more credible and integrated information to policy-makers. This will assist decision-making about the potential role of immunization in reducing the incidence of childhood neurological infections.     

The value of community participation in disease surveillance: a case study from Niger

A team of researchers, including one behavioral scientist (S.M.N.) and three epidemiologists (L.Q., O.S. and S.N.) conducted community analyses to assess the social and cultural factors that affect the detection and reporting of disease cases in a surveillance system, using acute flaccid paralysis (AFP) surveillance in Niger as a case study. Over a 60-day period in the country, the research team reviewed written field reports and interviewed epidemiologists, nurses, community members and persons in governmental and non-governmental organizations. Overall, we found that the logistical difficulties of travel and communication, which are common in developing countries, constrain the conventional surveillance system that relies on epidemiologists visiting sites to discover and investigate cases, particularly in rural areas. Other challenges include: community members' lack of knowledge about the possible link between a case of paralysis and a dangerous, communicable disease; lack of access to health care, including the low number of clinics and health care workers; cultural beliefs that favor seeking a local healer before consulting a nurse or physician; and health workers' lack of training in AFP surveillance. The quality of surveillance in developing countries can improve if a community-based approach is adopted. Such a system has been used successfully in Niger during smallpox-eradication and guinea worm-control campaigns. In a community-based system, community members receive basic education or more extensive training to motivate and enable them to notify health care staff about possible cases of disease in a timely fashion. Local organizations, local projects and local leaders must be included to ensure the success of such a program. In Niger we found sufficient quantities of this type of social capital, along with enough local experience of past health campaigns, to suggest that a community-based approach can improve the level of comprehensiveness and sensitivity of surveillance.     

Community participation and community-based rehabilitation: An Indonesian case study

Primary health care (PHC) and its commitment to community participation has been integral in the development of health care systems internationally. Community-based rehabilitation (CBR) and its grassroots approach to disability are closely allied with PHC and have adopted many of its principles, including that of participation. This paper briefly reviews the success of community participation with respect to PHC, and then examines the potential of an expanded notion of community participation within the realm of CBR. Although community participation is most often considered in the development and implementation of programmes, more recently, participation is being seen as an essential component of programme evaluation. The ideas presented here will be illustrated with examples from the author's research in Indonesia. As occupational therapy is increasing its focus on community-based practice and research, it is incumbent upon the profession to use the important lessons learned through more than 20 years of PHC, so that the goal of improving the lives of persons with disability world wide can be achieved.     

Rejection and reincorporation: A case study in social research utilisation

The utilisation and diffusion of the results of social research have been of interest to applied researchers, policy makers, and sociologists of science. In this paper a case study is presented, based on a research project carried out in the 1950s in a therapeutic community and published in Community as Doctor, 1960. The book had a mixed reception, both from its subjects (who were also its sponsors) and the academic community. Here these reactions are examined with respect to the actual development of the project, the reactions of the subjects to the findings, and finally the changing perceptions and uses that other social scientists made of the work. It is argued that it is essential in applied social research to view both the subjects and the researchers in a dynamic framework of change and development, if potential application points are to be engaged. In the research in question, the research team were external to the subjects' organisation and oriented to the norms of the academic community. The subjects, for their part, were involved in an innovative program of psychiatric reform, the heyday of which preceded the research. Thus the results came at a time when scientific and policy interests in social psychiatric ideas were declining. These divergences contributed to an initial rejection of the research findings by the subjects. However over a longer period it was found that the book came to have a quite widespread influence in the field, and was eventually embraced by the therapeutic community as a guide to their problem solving. It is concluded that the splitting and consequent “rejection phenomenon” surrounding applied research projects can be avoided by planning for collaboration in a framework that recognises the two sets of issues and processes—scientific and practical. Five maxims are suggested as guides.     

Health findings from a mortality and morbidity surveillance of refinery employees

PURPOSE: To present results from a prospective mortality (1973-1998) and morbidity (1990-1998) surveillance of a refinery population in California. METHODS: Mortality and illness-absence data were extracted from the Shell Oil Company's Health Surveillance System (HSS). Mortality data were compared to the United States, the state of California, and Contra Costa County, where the refinery is located. Morbidity data were compared to other company manufacturing employees. The standardized mortality/morbidity ratio (SMR/SMbR) was used as a measure of risk. Morbidity frequency and duration of absence were calculated by age, sex, and four health risk factors (smoking, high blood pressure, hypercholesterolemia, and obesity). RESULTS: With the United States as a comparison, the all causes combined SMR was 0.84 [95% confidence interval (CI) = 0.78-0.90], and the SMR for all cancer was 0.75 (95% CI = 0.64-0.88). Statistically significant deficits in mortality were found for lung cancer (SMR = 0.60) and leukemia (SMR = 0.26). Morbidity frequency and duration of absence among smokers were substantially higher than those of nonsmokers. Similar results were also noted for obese employees when compared to those of normal weight. CONCLUSIONS: Regardless of the comparison population, significantly fewer deaths were seen for all causes combined, all cancer, lung cancer, and leukemia. The study also showed no increased mortality from cancer of the stomach, kidney, skin, prostate, and brain. The increased morbidity frequency and duration of absence were associated with the presence of known health risk factors. These study findings are useful in setting priorities for medical programs and directing efforts such as health promotion and disease prevention strategies.     

Analysis of surveillance data with Poisson regression: a case study

One way to examine the ability of a statistical technique to detect changes in surveillance data is to analyse data sets with known changes and observe how accurately these changes can be detected. The elimination of restrictions on legal abortions should have reduced mortality associated with abortions, particularly mortality associated with illegal abortions. The sensitivity of Poisson regression to detect changes in abortion associated mortality from 1962 to 1984 was assessed for the entire United States of America and for specific states. Although it is clear that this change occurred using data from the entire United States, only the largest of the individual state data sets examined (370 events over 23 years) consistently demonstrated the expected pattern. Inconsistent patterns were found in data sets from two states with between one-fourth and one-half this number of events. The legal change was not detected at all in three states with a small number of events (1 event per year or less). From this case study, a minimum of two or three events per year seems to be necessary before Poisson regression can detect outliers. Comparisons of the four tests used suggest that tests based on model deviance are superior to tests based on comparison of observed and expected number of events.     

Perceptions about hospice from a community-based pilot study: lessons and findings

Research investigating the knowledge and attitudes of diverse older adults about hospice care and end-of-life issues is needed to expand service utilization. This pilot study explored an urban area's perceptions and awareness of hospice through local churches. The sample consisted of 148 adults age 43 and older. Although recruitment efforts resulted in a relatively homogenous sample, findings suggest a lack of knowledge about whether hospice is covered by Medicare, Medicaid, or private insurance. Perceptions of the expense of hospice, however, were not associated with knowledge of coverage. Respondents generally agreed that hospice is important and would recommend its services for their family members.     

The actual and potential costs of meningitis surveillance in the African meningitis belt: Results from Chad and Niger

BackgroundThe introduction of serogroup A meningococcal conjugate vaccine in the African meningitis belt required strengthened surveillance to assess long-term vaccine impact. The costs of implementing this strengthening had not been assessed.MethodologyThe ingredients approach was used to retrospectively determine bacterial meningitis surveillance costs in Chad and Niger in 2012. Resource use and unit cost data were collected through interviews with staff at health facilities, laboratories, government offices and international partners, and by reviewing financial reports. Sample costs were extrapolated to national level and costs of upgrading to desired standards were estimated.ResultsCase-based surveillance had been implemented in all 12 surveyed hospitals and 29 of 33 surveyed clinics in Niger, compared to six out of 21 clinics surveyed in Chad. Lumbar punctures were performed in 100% of hospitals and clinics in Niger, compared to 52% of the clinics in Chad. The total costs of meningitis surveillance were US$ 1,951,562 in Niger and US$ 338,056 in Chad, with costs per capita of US$ 0.12 and US$ 0.03, respectively. Laboratory investigation was the largest cost component per surveillance functions, comprising 51% of the total costs in Niger and 40% in Chad. Personnel resources comprised the biggest expense type: 37% of total costs in Niger and 26% in Chad. The estimated annual, incremental costs of upgrading current systems to desired standards were US$ 183,299 in Niger and US$ 605,912 in Chad, which are 9% and 143% of present costs, respectively.ConclusionsNiger's more robust meningitis surveillance system costs four times more per capita than the system in Chad. Since Chad spends less per capita, fewer activities are performed, which weakens detection and analysis of cases. Countries in the meningitis belt are diverse, and can use these results to assess local costs for adapting surveillance systems to monitor vaccine impact.     

Domestic violence in rural Uganda: evidence from a community-based study

Although domestic violence is an increasing public health concern in developing countries, evidence from representative, community-based studies is limited. In a survey of 5109 women of reproductive age in the Rakai District of Uganda, 30% of women had experienced physical threats or physical abuse from their current partner--20% during the year before the survey. Three of five women who reported recent physical threats or abuse reported three or more specific acts of violence during the preceding year, and just under a half reported injuries as a result. Analysis of risk factors highlights the pivotal roles of the male partner's alcohol consumption and his perceived human immunodeficiency virus (HIV) risk in increasing the risk of male against female domestic violence. Most respondents--70% of men and 90% of women--viewed beating of the wife or female partner as justifiable in some circumstances, posing a central challenge to preventing violence in such settings.     

Information and communication technology in disease surveillance,India: a case study

India has made appreciable progress and continues to demonstrate a strong commitment for establishing and operating a disease surveillance programme responsive to the requirements of the International Health Regulations (IHR[2005]). Within five years of its launch, India has effectively used modern information and communication technology for collection, storage, transmission and management of data related to disease surveillance and effective response. Terrestrial and/or satellite based linkages are being established within all states, districts, state-run medical colleges, infectious disease hospitals, and public health laboratories. This network enables speedy data transfer, video conferencing, training and e-learning for outbreaks and programme monitoring. A 24x7 call centre is in operation to receive disease alerts. To complement these efforts, a media scanning and verification cell functions to receive reports of early warning signals. During the 2009 H1N1 outbreak, the usefulness of the information and communication technology (ICT) network was well appreciated. India is using ICT as part of its Integrated Disease Surveillance Project (IDSP) to help overcome the challenges in further expansion in hard-to-reach populations, to increase the involvement of the private sector, and to increase the use of other modes of communication like e-mail and voicemail.     

Paradoxes and asymmetries of transnational networks: a comparative case study of Mexico's community-based AIDS organizations

This article examines whether transnational networks reconfigure state-civil society relationships in ways that lead to civil society empowerment and increased organizational capacity to address the HIV/AIDS epidemic in Mexico. Using a comparative case study, I identify the types of transnational networks and exchanges that both help and hinder community-based HIV/AIDS organizations (CBOs) that provide AIDS prevention and treatment services in Tijuana and Mexico City. Data derive from over 50 formal interviews, organizational documents and archival records, and observation. I argue that the form and function of transnational networks is shaped by the geo-political context of local organizational fields and that, in turn, transnational networks provide innovative opportunities for civil society-state partnerships that favor some local organizations over others. Ultimately, I take apart the prevailing assumption that transnational networks are inherently good, and show how they can (re)produce inter-organizational stratification at the local level. The conclusions of this research are helpful to international health practitioners and social scientists seeking to understand how civil society's participation in transnational networks can both challenge and reproduce existing community-state power regimes and health inequities.     

Assessing intervention effects in a community-based trial to reduce self-harm: a methodological case study

This paper considers the assessment of the impact of a community-based randomized controlled trial to reduce repeat deliberate self-harm. It considers the drawbacks in simplistic applications of conventional significance testing procedures, as well as possible failures regarding the statistical assumptions underlying such tests. Instead, the paper considers how relevant prior information might be incorporated within a fully Bayesian-model-based assessment procedure. The model includes a latent trait approach to patient morbidity; controlling for morbidity and other patient characteristics enhances the impact of the intervention (measured by a hazard rate ratio). If allowance is made for external information (e.g. ethical approval of the treatment), the weight of evidence shifts towards a positive intervention effect.     

Family health and health services utilisation in Belmont, Western Australia: a community case study

Abstract: This case study was designed to examine the self-defined health needs of families in one urban Western Australian community. We conducted 157 family interviews to examine the relationship between family sociodemographic variables and patterns of use of health services, which included services used within the previous 12 months, and what the family needed and wanted from these services. Questions covered perceptions of health, family health concerns and the role of the family health guardian. Quantitative analysis included frequencies, cross-tabulations, chi-squared tests and multiple regression analysis. Open-ended responses were categorised and analysed for common themes. Approximately 80 per cent of participants had used one or more health services during the previous 12 months and, despite 35.9 per cent of families having at least one family member with a long-standing illness, disability or infirmity, most (82.1 per cent) considered the family healthy. The correlational analysis revealed several associations. Predictably, younger persons reported higher health ratings and older persons had more health concerns. Larger families reported better perceived levels of health. Higher utilisation rates were recorded for families with children, who tended to use the general practitioner for general care and medication, whereas one-parent families used hospital and specialist care more often, and 98.7 per cent reported satisfaction with services. What they needed and wanted from their health service providers was 'full disclosure' and 'not being talked down to', and for specialists especially to be approachable and impart information simply and honestly.
