Chronic non-communicable diseases in Cameroon - burden, determinants and current policies

A functional health system is a necessary part of efforts to achieve maternal mortality reduction in developing countries. Puerperal sepsis is an infection contracted during childbirth and one of the commonest causes of maternal mortality in developing countries, despite the discovery of antibiotics over eighty years ago. Infections can be contracted during childbirth either in the community or in health facilities. Some developing countries have recently experienced increased use of health facilities for labour and delivery care and there is a possibility that this trend could lead to rising rates of puerperal sepsis. Drug and technological developments need to be combined with effective health system interventions to reduce infections, including puerperal sepsis. This article reviews health system infection control measures pertinent to labour and delivery units in developing country health facilities. Organisational improvements, training, surveillance and continuous quality improvement initiatives, used alone or in combination have been shown to decrease infection rates in some clinical settings. There is limited evidence available on effective infection control measures during labour and delivery and from low resource settings. A health systems approach is necessary to reduce maternal mortality and the occurrence of infections resulting from childbirth. Organisational and behavioural change underpins the success of infection control interventions. A global, targeted initiative could raise awareness of the need for improved infection control measures during childbirth.     

Barriers to the utilization of maternal health care in rural Mali

This study used data from the 2001 Demographic and Health Survey and multilevel logistic regression models to examine area- and individual-level barriers to the utilization of maternal health services in rural Mali. The analysis highlights a range of area-level influences on the use made of maternal health services. While the dearth of health facilities was a barrier to receipt of prenatal care in the first trimester, transportation barriers were more important for four or more prenatal visits, and distance barriers for delivery assistance by trained medical personnel and institutional delivery. Women's odds of utilizing maternal health services were strongly influenced by the practices of others in their areas of residence and by living in close proximity to people with secondary or higher education. Household poverty and personal problems were negatively related to all outcomes considered. The results highlight the importance of antenatal care and counseling about pregnancy complications for increasing the likelihood of appropriate delivery care, particularly among women living 15-29 km from a health facility. Area-level factors explained a greater proportion of the variation in delivery care than in prenatal care However, significant area variation in the utilization of maternal health services remained unexplained.     

Introduction to the practice of telemedicine

Telemedicine is the delivery of health care and the exchange of health-care information across distances. It is not a technology or a separate or new branch of medicine. Telemedicine episodes may be classified on the basis of: (1) the interaction between the client and the expert (i.e. realtime or prerecorded), and (2) the type of information being transmitted (e.g. text, audio, video). Much of the telemedicine which is now practised is performed in industrialized countries, such as the USA, but there is increasing interest in the use of telemedicine in developing countries. There are basically two conditions under which telemedicine should be considered: (1) when there is no alternative (e.g. in emergencies in remote environments), and (2) when it is better than existing conventional services (e.g. teleradiology for rural hospitals). For example, telemedicine can be expected to improve equity of access to health care, the quality of that care, and the efficiency by which it is delivered. Research in telemedicine increased steadily in the late 1990s, although the quality of the research could be improved--there have been few randomized controlled trials to date.     

Birth choices in Timor-Leste: a framework for understanding the use of maternal health services in low resource settings

The high rate of maternal mortality in Timor-Leste is a persistent problem which has been exacerbated by the long history of military occupation and ongoing political crises since independence in 1999. It is similar to other developing countries where there have been slow declines in maternal mortality despite 20 years of Safe Motherhood interventions. The national Ministry of Health, United Nations (UN) agencies and non-government organisations (NGOs) have attempted to reduce maternal mortality by enacting policies and interventions to increase the number of births in health centres and hospitals. Despite considerable effort in promoting facility-based delivery, most Timorese women birth at home and the lack of midwives means few women have access to a skilled birth attendant. This paper investigates factors influencing access to and use of maternal health services in rural areas of Timor-Leste. It draws on 21 interviews and 11 group discussions with Timorese women and their families collected over two periods of fieldwork, one month in September 2006 and five months from July to December 2007. Theoretical concepts from anthropology and health social science are used to explore individual, social, political and health system issues which affect the way in which maternal health services are utilised. In drawing together a range of theories this paper aims to extend explanations around access to maternal health services in developing countries. An empirically informed framework is proposed which illustrates the complex factors that influence women's birth choices. This framework can be used by policy-makers, practitioners, donors and researchers to think critically about policy decisions and where investments can have the most impact for improving maternal health in Timor-Leste and elsewhere.     

Huge poor-rich inequalities in maternity care: an international comparative study of maternity and child care in developing countries

OBJECTIVE: Progress towards the Millennium Development Goals for maternal health has been slow, and accelerated progress in scaling up professional delivery care is needed. This paper describes poor-rich inequalities in the use of maternity care and seeks to understand these inequalities through comparisons with other types of health care. METHODS: Demographic and Health Survey (DHS) data from 45 developing countries were used to describe poor-rich inequalities by wealth quintiles in maternity care (professional delivery care and antenatal care), full childhood immunization coverage and medical treatment for diarrhoea and acute respiratory infections (ARI). FINDINGS: Poor-rich inequalities in maternity care in general, and professional delivery care in particular, are much greater than those in immunization coverage or treatment for childhood illnesses. Public-sector inequalities make up a major part of the poor-rich inequalities in professional delivery attendance. Even delivery care provided by nurses and midwives favours the rich in most countries. Although poor-rich inequalities within both rural and urban areas are large, most births without professional delivery care occur among the rural poor. CONCLUSION: Poor-rich inequalities in professional delivery care are much larger than those in the other forms of care. Reducing poor-rich inequalities in professional delivery care is essential to achieving the MDGs for maternal health. The greatest improvements in professional delivery care can be made by increasing coverage among the rural poor. Problems with availability, accessibility and affordability, as well as the nature of the services and demand factors, appear to contribute to the larger poor-rich inequalities in delivery care. A concerted effort of equity-oriented policy and research is needed to address the huge poor-rich inequalities in maternity care.     

Maternal death: unequal risks

Nearly 99% of maternal deaths in the world each year occur in developing countries. New efforts have recently been undertaken to combat maternal mortality through research and action. The medical causes of such deaths are coming to be better understood, but the social mechanisms remain poorly grasped. Maternal mortality rates in developing countries are difficult to interpret because they tend to exclude all deaths not occurring in health care facilities. The countries of Europe and North America have an average maternal mortality rate of 30/100,000 live births, representing about 6000 deaths each year. The developing countries of Asia, Africa, and Latin America have rates of 270-640/100,000, representing some 492,000 deaths annually. For a true comparison of the risks of maternal mortality in different countries, the risk itself and the average number of children per woman must both be considered. A Nigerian woman has 375 times greater risk of maternal death than a Swedish woman, but since she has about 4 times more children, her lifetime risk of maternal death is over 1500 times greater than that of the Swedish woman. The principal medical causes of maternal death are known: hemorrhages due to placenta previa or retroplacental hematoma, mechanical dystocias responsible for uterine rupture, toxemia with eclampsia, septicemia, and malaria. The exact weight of abortion in maternal mortality is not known but is probably large. The possible measures for improving such rates are of 3 types: control of fertility to avoid early, late, or closely spaced pregnancies; effective medical surveillance of the pregnancy to reduce the risk of malaria, toxemia, and hemorrhage, and delivery in an obstetrical facility, especially for high-risk pregnancies. Differential access to high quality health care explains much of the difference between mortality rates in urban and rural, wealthy and impoverished areas of the same country. The social determinants of high maternal mortality rates include political, geographic, and economic mechanisms of exclusion which affect the vast majority of the population in developing countries. Political power is concentrated in the hands of relatively small groups whose decisions about such expenditures as health care are usually more favorable to the privileged. A consequence of the very unequal regional development in most Third World countries is that health, educational, and most other resources are concentrated in large cities and perhaps 1 or 2 strategic regions, leaving most of the population underserved. The low social position of women leaves them doubly vulnerable. The social factors adding to risks of maternal mortality should be considered in programs of prevention if the causes and not just the consequences are to be addressed.     

Inequality and changes in women's use of maternal health-care services in Tajikistan

Using recently available survey data for Tajikistan, this study explores changes in the pattern of maternal health care during the last decade and the extent to which inequalities in access to that care have emerged. In particular, the links between poverty and women's educational status and the use of maternal health-care services are investigated. The survey findings demonstrate a significant decline in the use of maternal health-care services in Tajikistan since the country gained independence from the Soviet Union in 1991. They show changes in the location of delivery and the person providing assistance, with a clear shift away from giving birth in a medical facility toward giving birth at home. More than two-fifths of all women who gave birth in the year prior to the survey delivered their baby at home. Women from the poorest quintile are three times more likely than women from the richest quintile to undergo a home delivery without a trained assistant.     

A Framework for Analyzing the Determinants of Obstetric Fistula Formation

Obstetric fistula, a devastating complication of prolonged obstructed labor, was once common in the Western world but now occurs almost exclusively in resource‐poor countries. Although much has been written about the surgical repair of obstetric fistulas, prevention of fistulas has garnered comparatively little attention. Because obstetric fistulas result from obstructed labor (one of the common causes of maternal death in impoverished countries), this study assesses the obstetric fistula problem using a framework originally developed to analyze the determinants of maternal mortality. The framework identifies and explicates three sets of determinants of obstetric fistulas: the general socioeconomic milieu in which such injuries occur (the status of women, their families, and their communities); intermediate factors (health, reproductive status, and use of health care resources); and the acute clinical factors that determine the ultimate outcome of any particular case of obstructed labor. Interventions most likely to work rapidly in fistula prevention are those that have a direct impact on acute clinical situations, but these interventions will only be effective when general socioeconomic and cultural conditions promote an enabling environment for health care delivery and use. Sustained efforts that impact all three levels of determining factors will be necessary to eradicate obstetric fistula.     

Private sector contributions and their effect on physician emigration in the developing world

The contribution made by the private sector to health care in a low- or middle-income country may affect levels of physician emigration from that country. The increasing importance of the private sector in health care in the developing world has resulted in newfound academic interest in that sector’s influences on many aspects of national health systems. The growth in physician emigration from the developing world has led to several attempts to identify both the factors that cause physicians to emigrate and the effects of physician emigration on primary care and population health in the countries that the physicians leave. When the relevant data on the emerging economies of Ghana, India and Peru were investigated, it appeared that the proportion of physicians participating in private health-care delivery, the percentage of health-care costs financed publicly and the amount of private health-care financing per capita were each inversely related to the level of physician expatriation. It therefore appears that private health-care delivery and financing may decrease physician emigration. There is clearly a need for similar research in other low- and middle-income countries, and for studies to see if, at the country level, temporal trends in the contribution made to health care by the private sector can be related to the corresponding trends in physician emigration. The ways in which private health care may be associated with access problems for the poor and therefore reduced equity also merit further investigation. The results should be of interest to policy-makers who aim to improve health systems worldwide.     

Unintended pregnancies and the use of maternal health services in southwestern Ethiopia

Background

The benefits of maternal health care to maternal and neonatal health outcomes have been well documented. Antenatal care attendance, institutional delivery and skilled attendance at delivery all help to improve maternal and neonatal health. However, use of maternal health services is still very low in developing countries with high maternal mortality including Ethiopia. This study examines the association of unintended Pregnancy with the use of maternal health services in Southwestern Ethiopia.

Methods

Data for this study come from a survey conducted among 1370 women with a recent birth in a Health and Demographic Surveillance Site (HDSS) in southwestern Ethiopia. An interviewer administered questionnaire was used to gather data on maternal health care, pregnancy intention and other explanatory variables. Data were analyzed using STATA 11, and both bivariate and multivariate analyses were done. Multivariate logistic regression was used to assess the association of pregnancy intention with the use of antenatal and delivery care services. Unadjusted and adjusted odds ratio and their 95% confidence intervals are reported.

Results

More than one third ( 35%) of women reported that their most recent pregnancy was unintended. With regards to maternal health care, only 42% of women made at least one antenatal care visit during pregnancy, while 17% had four or more visits. Institutional delivery was only 12%. Unintended pregnancy was significantly (OR: 0.75, 95% CI, 0.58-0.97) associated with use of antenatal care services and receiving adequate antenatal care (OR: 0.67, 95% CI, 0.46-0.96), even after adjusting for other socio-demographic factors. However, for delivery care, the association with pregnancy intention was attenuated after adjustment. Other factors associated with antenatal care and delivery care include women’s education, urban residence, wealth and distance from health facility.

Conclusions

Women with unintended pregnancies were less likely to access or receive adequate antenatal care. Interventions are needed to reduce unintended pregnancy such as improving access to family planning information and services. Moreover, improving access to maternal health services and understanding women’s pregnancy intention at the time of first antenatal care visit is important to encourage women with unintended pregnancies to complete antenatal care.

     

Mothers’ perceptions and experiences of using maternal health-care services in Rwanda

Reducing barriers to use maternal health care is one of the critical components to improving maternal health. Rwanda is among the countries that have made tremendous efforts to reduce maternal mortality. However, the current maternal mortality ratio is still high which calls for further efforts to be considered. This study used a qualitative approach to understand mothers’ perceptions and experiences of using maternal health care in Rwanda. Using in-depth interviews and focus group discussions, data were collected in the Western and Eastern provinces of the country where forty-five women participated in the study from June to August 2014. This paper highlights perceptions of these participants regarding issues that contribute to suboptimal use of maternal health-care services. The geographical, financial, and social–cultural barriers that emerged in this study highlight the need to understand mothers’ experiences and perceptions when using maternal health care as Rwanda and other countries strive to reduce negative maternal health outcomes.     

The impact of age on cost-effectiveness ratios and its control in decision making

Throughout Europe and in a number of other industrialized countries, the coming decades have been predicted to feature an increase in the proportion of patients who are elderly. This has led to considerable concern with respect to financing the health care system and has also increased the concerns about the efficiency of health care. Integrating ageing and efficiency issues, this paper examines the effects of age on the cost-effectiveness of medical interventions and its impact on decision making. First, at the clinical level, the relation between age and the cost-effectiveness of medical interventions is analysed. Second, at the population level, a framework is presented which allows researchers and decision makers to assess the impact of these effects on the decision-making process. It is shown that the allocation of health care resources at the macro-level is seriously impaired when age is ignored as a variable in cost-effectiveness analysis. Because clinical trials typically employ ‘young’ populations, when the data are extrapolated to the whole population the attractiveness of medical interventions in terms of cost-effectiveness may be considerably overestimated. Furthermore, the cost-effectiveness ratio may vary across countries or over time as a result of demographic or epidemiological variation. Economic evaluators should describe the impact of age, which should then be considered by decision makers to control for age effects.     

An assessment of the telehealth needs and health-care priorities of Tanna Island: a remote, under-served and vulnerable population

We surveyed eight Canadian physicians who had each provided medical care for six months on the remote and under-served island of Tanna in Vanuatu. The most frequently encountered medical problems on Tanna were infectious diseases (tuberculosis, hepatitis, abscesses, malaria, pneumonia, typhoid fever, meningitis and skin infections). When physicians were asked about the top three health-care priorities, they ranked tuberculosis control, clean water and improved health-care delivery/communication between hospital and outposts as most important. The key issues were: (1) basic public health needs and infrastructure development are higher in priority than telehealth; (2) telehealth consultants must have knowledge pertinent to local conditions and resources available to the population; (3) electronic equipment suited to tropical environments is needed; (4) projects must be developed locally rather than internationally. Understanding how telehealth can provide support to health professionals under challenging conditions may assist with the health priorities in developing countries and potentially provide access to resources both locally and internationally.     

Factors associated with the use of maternity services in Enugu, southeastern Nigeria

The maternal mortality ratio and other maternal health indicators are worse for developing countries than for the developed world due to improved access to quality care during pregnancy and especially at delivery in the industrialized world. This study was carried out to identify the factors which influenced choice of place of delivery by pregnant women in Enugu, southeastern Nigeria, and to recommend ways to improve women's access to skilled attendants at delivery. A pre-tested questionnaire was administered by interviewers to women who had delivered within 3 months prior to date of data collection. The response rate was 75.5% (n=1098). Of the respondents, 52.9% delivered outside health institutions and 47.1% in health institutions. The major factors influencing choice of place of delivery included promptness of care, competence of midwife/doctor, affordability, health education, 24 h presence of doctors, team work among doctors and presence of specialist obstetricians. There were statistically significant associations between choice of institutional or non-institutional deliveries and socio-demographic/economic factors such as place of residence (urban/rural), religion, educational status, tribe, marital status, occupational level, husband's occupational and educational levels, age and parity (p<0.05). We conclude that factors which will positively influence women to deliver in health institutions in Enugu, Nigeria include a variety of interacting social, economic and health system factors, which operate at various levels-the household, community, the health institutions and the larger social and political environment. Attention to these factors will not only improve maternity utilization but, hopefully, also will reduce the high maternal mortality and improve other maternal health indicators in the study area.     

Quality of care assessment of public and private outpatient clinics in Metro Cebu,the Philippines

Despite large investments in primary health care in developing countries, evaluation of the quality of services has been neglected. Managers need information on service quality to identify specific ways to improve health-care delivery, and to determine how health programs can achieve their desired effects. We tested several quality-assessment methods in 48 public and private outpatient clinics in Metro Cebu, The Philippines. Structured observations of immunization sessions and clinic logistics highlighted functional problems at particular clinics that contributed to shortages of vaccines, sterilized needles and oral rehydration salts (ORS). Quality assessment of medical records for the treatment of diarrhea revealed a wide variation in the recorded quality of services. Clinical case histories were presented to public and private providers, who advised different approaches for case management, highlighting areas where improvement is needed. For example, public providers were more likely to use ORS to treat dehydration; private providers were more likely to enquire about symptoms of dysentery. Private providers were more likely to treat a mild respiratory infection with antibiotics, but few providers were likely to prescribe antibiotics for a child with signs suggestive of severe pneumonia. Advice to mothers was insufficient in most areas. These quality-assessment methods can be used by managers to develop training curricula and solve problems in the delivery of primary health-care services.     

Inequity in maternal health-care services: evidence from home-based skilled-birth-attendant programmes in Bangladesh

OBJECTIVE: To explore use-inequity in maternal health-care services in home-based skilled-birth-attendant (SBA) programme areas in Bangladesh. METHODS: Data from a community survey, conducted from February to May 2006, were analysed to examine inequities in use of SBAs, caesarean sections for deliveries and postnatal care services according to key socioeconomic factors. FINDINGS: Of 2164 deliveries, 35% had an SBA, 22.8% were in health facilities and 10.8% were by caesarean section. Rates of uptake of antenatal and postnatal care were 93% and 28%, respectively. There were substantial use-inequities in maternal health by asset quintiles, distance, and area of residence, and education of both the woman and her husband. However, not all inequities were the same. After adjusting for other determinants, the differences in the use of maternal health-care services for poor and rich people remained substantial [adjusted odds ratio (OR) 2.51 (95% confidence interval, CI: 1.68-3.76) for skilled attendance; OR 2.58 (95% CI: 1.28-5.19) for use of caesarean sections and OR 1.53 (95% CI: 1.05-2.25) for use of postnatal care services]. Complications during pregnancy influenced use of SBAs, caesarean-section delivery and postnatal care services. The number of antenatal care visits was a significant predictor for use of SBAs and postnatal care, but not for caesarean sections. CONCLUSION: Use of maternity care services was higher in the study areas than national averages, but a tremendous use-inequity persists. Interventions to overcome financial barriers are recommended to address inequity in maternal health. A greater focus is needed on the implementation and evaluation of maternal-health interventions for poor people.     

Patient involvement in patient safety: what factors influence patient participation and engagement?

BACKGROUND: Patients can play an important role in improving patient safety by becoming actively involved in their health care. However, there is a paucity of empirical data on the extent to which patients take on such a role. In order to encourage patient participation in patient safety we first need to assess the full range of factors that may be implicated in such involvement. OBJECTIVE: To delineate factors that could affect the participation of the patient in quality and safety issues in their health care. METHOD: Literature review of patient involvement in health care, drawing from direct evidence (specifically from the safety context) and indirect evidence (extrapolated from treatment decision-making research and the wider patient involvement in health care literature); synthesis and conceptual framework developed, illustrating the known and putative factors that could affect the participation of the patient in safety issues in their health care. MAIN RESULTS: Five categories of factors emerged that could affect patient involvement in safety: patient-related (e.g. patients' demographic characteristics), illness-related (e.g. illness severity), health-care professional-related (e.g. health care professionals' knowledge and beliefs), health care setting-related (e.g. primary or secondary care), and task-related (e.g. whether the required patient safety behaviour challenges clinicians' clinical abilities). CONCLUSION: The potential for engaging patients in patient safety is considerable but further research is needed to examine the influences on patient involvement, the limits and the possible dangers. Patients can act as 'safety buffers' during their care but the responsibility for their safety must remain with the health care professionals.     

Geographical variations in mortality due to diseases amenable to medical intervention in Europe--Commission of European Communities: atlas of avoidable deaths

The urgent need to develop measures of the outcome of health-care services has led to the collaboration of 10 countries of the European Community in the production of the European Community atlas of avoidable death (1974-1978). Seventeen disease groups were chosen for which it was considered that death within specified age groups should be either wholly or substantially avoidable when appropriate medical care is sought and provided in good time. Mortality from these causes was compared across 360 health-service administrative areas in the participating countries. For all diseases there was considerable variation in mortality both within and between the countries of the European Community and it is suggested that high levels of mortality from these causes should be viewed by health authorities as warning signals of potential failures of health-care services. Work is in progress on a further edition of the Atlas for the years 1980-1984. Changes in avoidable mortality over time could indicate which health authorities have persistent problems and which authorities are succeeding in reducing avoidable mortality.     

Extending community involvement in the medical curriculum: lessons from a case study

OBJECTIVES: Recent reports have stressed the importance of developing medical students' understanding of primary and community care and their ability to work in health-care teams. DESIGN: An innovative 3-year project aimed to achieve this understanding by broadening the range of health-care professionals and community organizations contributing to the medical curriculum. SETTING: King's College School of Medicine, London. SUBJECTS: Undergraduate medical students. RESULTS: Through partnerships with three local community health care trusts, non-medical health care disciplines in the teaching hospital and a range of voluntary and statutory services, students have been introduced to a broader spectrum of care. This has taken place both within the core curriculum and through the development of special study modules. CONCLUSIONS: Involving teachers and organizations which have not traditionally contributed to medical education raises philosophical issues around the aims and rationale of their involvement and practical issues such as gaining curriculum time, recruiting suitable teachers and gaining credibility for the courses. We analyse the benefits and difficulties inherent in broadening the curriculum in this way and assess the lessons our experience provides for the future expansion of such learning, both locally and nationally.
