Maternal mortality in developed countries: not just a concern of the past.

OBJECTIVE: To review the activities in selected developed countries for strategies to identify maternal deaths, the impact of these strategies on underreporting, and the information needed to understand the events leading to death. DATA SOURCES: We reviewed the literature from the United States, Europe, and Australia for publications dealing with maternal death identification and investigation from 1980 to April 1995. We also obtained information directly from researchers involved in major maternal mortality studies. METHODS OF STUDY SELECTION: We included all 31 reports (from 14 countries) that discussed methods to improve the ascertainment of maternal deaths beyond the routine use of vital registration. Because of the nature of the subject matter, almost all reports relied on descriptive epidemiology. DATA EXTRACTION AND SYNTHESIS: We found that a variety of methods can be used to improve the ascertainment of maternal deaths, including linkage of birth and fetal death certificates, check-boxes on death certificates, periodic review of deaths of reproductive-age women, and ongoing birth registries and medical audits. Information from a variety of sources is also needed to understand the events leading to death. CONCLUSION: The numbers of deaths due to pregnancy and its complications are underestimated in most developed countries. Improved ascertainment of maternal death is needed to determine the magnitude of the problem and to assess trends and identify risk groups, allowing development of appropriate and effective strategies to prevent the morbidity and mortality associated with pregnancy.

Constraints to the implementation of effective environmental management in coastal areas of developing countries.

This paper addresses the limitations the scarcity of reliable scientific information poses to the implementation of effective and sustainable coastal management programmes in developing countries. Alternatives to the current monitoring approaches are suggested as to improve information level on the state of the environment and to decrease data gap on past conditions. The paper aims at encouraging the redesign of monitoring practices in developing countries as to be ground on the best actual scientific knowledge.

Malnutrition and health in developing countries.

Malnutrition, with its 2 constituents of protein-energy malnutrition and micronutrient deficiencies, continues to be a major health burden in developing countries. It is globally the most important risk factor for illness and death, with hundreds of millions of pregnant women and young children particularly affected. Apart from marasmus and kwashiorkor (the 2 forms of protein- energy malnutrition), deficiencies in iron, iodine, vitamin A and zinc are the main manifestations of malnutrition in developing countries. In these communities, a high prevalence of poor diet and infectious disease regularly unites into a vicious circle. Although treatment protocols for severe malnutrition have in recent years become more efficient, most patients (especially in rural areas) have little or no access to formal health services and are never seen in such settings. Interventions to prevent protein- energy malnutrition range from promoting breast-feeding to food supplementation schemes, whereas micronutrient deficiencies would best be addressed through food-based strategies such as dietary diversification through home gardens and small livestock. The fortification of salt with iodine has been a global success story, but other micronutrient supplementation schemes have yet to reach vulnerable populations sufficiently. To be effective, all such interventions require accompanying nutrition-education campaigns and health interventions. To achieve the hunger- and malnutrition-related Millennium Development Goals, we need to address poverty, which is clearly associated with the insecure supply of food and nutrition.

The I.C.U. treatment of acute laryngotracheobronchitis in a developing country.

The management of 50 children with acute laryngotracheobronchitis (LTB) in a general I.C.U. in a developing country is presented. The overall mortality was 16%, with no patient demising from LTB. It is stressed that LTB in developing countries is a very different disorder to that seen in Western societies, due to complicating factors such as bronchopneumonia, malnutrition and measles. Guidelines for therapy are proposed.

The epidemiologic transition to chronic diseases in developing countries: cardiovascular mortality, morbidity, and risk factors in Seychelles (Indian Ocean). Investigators of the Seychelles Heart Study.

The occurrence of cardiovascular diseases (CVD) and related risk factors was evaluated in Seychelles, a middle level income country, as accumulating evidence supports increasing rates of CVD in developing countries. CVD mortality was obtained from vital statistics for two periods, 1984-5 and 1991-3. CVD morbidity was estimated by retrospective review of discharge diagnoses for all admissions to medical wards in 1990-1992. Levels of CVD risk factors in the population were assessed in 1989 through a population-based survey. In 1991-93, standardized mortality rates were in males and females respectively, 80.9 and 38.8 for cerebrovascular disease and 92.9 and 47.0 for ischemic heart disease. CVD accounted for 25.2% of all admissions to medical wards. Among the general population aged 35-64, 30% had high blood pressure, 52% of males smoked, and 28% of females were obese. These findings substantiate the current health transition to CVD in Seychelles. More generally, epidemiologic data on CVD mortality, morbidity, and related risk factors, as well as similar indicators for other chronic diseases, should more consistently appear in national and international reports of human development to help emphasize, in the health policy making scene, the current transition to chronic diseases in developing countries and the subsequent need for appropriate control and prevention programs.

Nutrition for preterm and growth retarded infants: developing country concerns.

The problems of feeding preterm and low birth weight infants are discussed. Physiological requirements are considered, together with the ways in which these can be met in developed and developing countries. Although human milk may not always be considered best for preterm infants in developed countries it is concluded that in underprivileged areas of the Third World it is life saving.

Vaccinations in the health strategies of developing countries.

The initiative established by the World Health Organization in 1974 under the title of the Expanded Programme on Immunization (EPI) has resulted in immunization programmes being strengthened in developing countries so that they now cover 66% of children reaching their first birthday with a dose of DPT or polio vaccines. Immunization programmes are currently preventing over 2 million deaths among children in developing countries from measles, neonatal tetanus and whooping cough. Future challenges for the EPI include: raising and sustaining immunization coverage; controlling the target diseases, with specific focus on the control of measles, the elimination of neonatal tetanus and the eradication of poliomyelitis; introducing new or improved vaccines; promoting other primary health care practices; and research and development. Immunization will become an increasing priority for developing and industrialized countries alike as an increasing array of vaccines become available for public health use. Further research to simplify and reduce the costs of vaccine production and administration and to better understand the factors contributing to the acceptability of immunization services is needed as a complement to research to develop additional vaccines.

Duration of untreated psychosis and outcome in first-episode psychosis. Perspective from a developing country.

OBJECTIVE: To investigate the association between duration of untreated psychosis (DUP) and treatment outcome in a sample of subjects from a developing country. METHOD: Forty-eight subjects with a first episode of psychosis were evaluated prior to treatment and at 3-month intervals over a period of 24 months. We first examined correlations between DUP and symptom improvement as measured on the Positive and Negative Symptom Scale (PANSS), and then performed multivariate analysis to determine the validity of DUP as a predictor of outcome. RESULTS: DUP was significantly correlated with improvement in PANSS total and negative subscale scores as well as the PANSS depression factor at 21 and 24 months. Multivariate analysis found DUP to be the only significant predictor of improvement in negative symptoms at 24 months. CONCLUSION: DUP was a significant predictor of outcome in a cohort form a developing country. This study provides support for early detection and intervention strategies.

[Resistance problems in developing countries--use and misuse of antiinfective agents].

Widespread use and misuse of antiinfectiva have resulted in a problem of drug resistance linked to treatment of infectious diseases. In developing countries especially, the sale of such drugs is poorly controlled and the pharmaceutical industry is dumping obsolete products. Intensive marketing, lack of diagnostic facilities and receptive local cultural attitudes to new "wonder drugs" such as antibiotics, have resulted in dramatic unnecessary use of such. Therefore the ideal strategies for treatment of infectious diseases guided by microbiological diagnosis and resistance pattern are violated in most developing countries, leading to excessive use of antiinfectiva and development of resistance. This has serious consequences for the infections that cause most cases of infant mortality, namely malaria, diarrhoeas and infections of the respiratory tract. Improvements in this vicious circle of drug use and resistance can only be made by attacking several factors simultaneously. There is a need for general information, stricter legislation, essential drug lists, national drug policies, better knowledge of local resistance patterns, better diagnostic facilities, better knowledge about local beliefs about drugs and better communication to local health workers and the community.

Epidemiology of international terrorism involving fatal outcomes in developed countries (1994-2003).

We aimed to describe the public health burden and epidemiology of international terrorism (i.e. involving foreign nationals) with fatal outcomes in developed countries. Data was abstracted from a United States Department of State database for 21 'established market economy' countries and 18 'former socialist economies of Europe' for 1994-2003. To put the findings in a wider context, comparisons were made with WHO data on all homicides for each country. A total of 32 international terrorist attacks causing fatalities were identified over the 10-year period. These resulted in 3299 deaths, giving a crude annual mortality rate of 0.3 per million population. The mortality burden attributable to international terrorism in these countries was 208 times less than that attributable to other homicide. Even for the country with the highest mortality burden from international terrorism (the United States), this ratio was 60. There was no statistically significant trend in the number of attacks over time, but the attack severity (in terms of deaths per attack) was higher in the latter part of the 10-year period. A number of limitations with this data set were identified. If a more rigorous definition of 'international terrorism' was used, then this would substantially reduce the total number of such attacks defined in this way. In conclusion, there is a need for better quality data and improved classification systems for describing international terrorism. Nevertheless, the available data indicates that the mortality burden from international terrorism in developed countries is small compared to that from other homicide.

Poliomyelitis in developing countries: lower limb paralysis and injections.

The distribution of muscle paralysis due to poliomyelitis is different in temperate and tropical countries. In temperate countries, 49% of children with paralysis were affected only in the legs compared with 85% in developing countries, 79% and 89% respectively had affected legs with other paralysis. This suggests that correction for lameness surveys is unnecessary. Muscles frequently injected and those with adjacent motor neurone tracts in the central nervous system were much more frequently affected in Nigerian than in UK children, whereas paralysis in other muscles was less frequent than in the UK children. This and other evidence points to a major causal role for injections in the high prevalence of polio in developing countries. Proof may however be impossible to obtain because less than 0.5% of all injections are followed by paralysis. There may also be damage to motor neurones, without paralysis, which may lead to later disabilities. Injections should be given to young children only when absolutely necessary.

A prospective survey of intra-operative critical incidents in a teaching hospital in a developing country.

Critical incident monitoring has the advantage of identifying a potential risk to the patient without it necessarily resulting in morbidity. An added advantage in developing countries is the low cost involved in introducing the programme. This paper analyses the incidents reported from the operating room suite in a teaching hospital in a developing country from August 1997 to 31 December 1999. During the period, 20 819 anaesthetics were administered and 329 incidents were reported (1.58% of the cases). Seventy-three per cent of the incidents were reported in patients of ASA grade 1 or 2. Thirty-nine per cent occurred during induction, 51% during maintenance and 10% during emergence. Human error was the cause in 41%, equipment error in 50% and system error in 8.5%. Twenty-two per cent of the incidents resulted in minor, and 13% in major physiological disturbance. The technique has been found useful in identifying trends and selecting issues to be discussed in departmental quality assurance meetings, but requires persistent motivation of the reporting staff.

The health of the workers in a rapidly developing country: effects of occupational exposure to noise and heat.

Occupational hygiene and safety have not been high on the agenda of industrial management in developing countries for a variety of reasons. This cross-sectional study was undertaken to assess the exposure to noise and heat, and to study the level of occupational hygiene practiced, at a foundry in a rapidly developing country (Dubai, United Arab Emirates). Audiometry, muscle cramps and visual acuity were measured in workers at a foundry and compared with the results from workers at a soft-drink bottling plant. Thermal stress, relative humidity, ventilation, illumination and noise levels were measured at different work units at the foundry and at the soft-drink bottling factory. Thermal stress index was high while relative humidity and ventilation were low at the foundry compared with the bottling plant. Noise levels were also high at the foundry, exceeding 90 dB at almost all work units except the fabrication workshop. Mild or moderate visual defects were observed among 31% of foundry workers, compared with 19% of the bottling plant workers.Muscle cramps were reported by 30% of all workers at the foundry, compared with 5% at the bottling plant. Visual disability was the highest among furnace operators and fabricators. Mean hearing disability was 8.69 +/- 1.08% among foundry workers, compared with 4.56 +/- 0.82% among bottling plant workers. The high thermal stress, noise levels and exposure to non-ionizing radiations at the foundry might have contributed to the higher frequency of muscle cramps and the greater hearing and visual disabilities, respectively, among these workers. Non-use of personal protective equipment and poor occupational hygiene and safety measures were also seen to affect eye and ear health adversely among the workers at the foundry.

The ethics of developed nations recruiting nurses from developing countries: the case of Malawi.

There is currently a global shortage of nurses. Developing countries such as Malawiare among those hardest hit by this shortage. The demands on available nurses have increased and at the same time there is a lack of interest in becoming a nurse owing to the poor working conditions among those still employed in the service. It is questionable if developed nations should recruit nurses from countries such as Malawi, where severe human resource constraints are being experienced. We argue in this article that the current phenomenon of nurses leaving developing nations for western countries is complex. Human rights issues of individual autonomy and public interest are at stake.

Health information technology in primary health care in developing countries: a literature review.

This paper explores the debate and initiatives concerning the use of information technology (IT) in primary health care in developing countries. The literature from 1992-2002 was identified from searches of the MEDLINE, Latin American and Caribbean Health Science Literature Database (LILACS), Cochrane Library and Web of Science databases. The search identified 884 references, 350 of which were classified according to the scheme described by the Pan American Health Organization (PAHO). For the analysis of advantages, problems and perspectives of IT applications and systems, 52 articles were selected according to their potential contribution to the primary health-care processes in non-developed countries. These included: 10 on electronic patient registries (EPR), 22 on process and programmatic action evaluation and management systems (PPAEM) and 20 on clinical decision-support systems (CDS). The main advantages, limitations and perspectives are discussed.

Studies of the epidemiology of dementia: comparisons between developed and developing countries.

By the year 2025, 68% of the world's population aged 65 and above, nearly 277 million people, will be residing in developing countries. The less industrialized nations have been the least studied to date, and may yield significant new information about the etiology and risk factors for Alzheimer's disease (AD) and other dementias. Although it is readily apparent that cross-national and cross-cultural comparisons are desirable, these can be meaningful only if based on comparable methodology. In this work we will discuss some general conceptual and methodological issues regarding epidemiological studies of dementia in developing countries. The topics discussed include community-based screening for dementia, screening instruments and their application in cross-cultural studies, steps in standardization of new or modified neuropsychological tests, and some special considerations in studying uneducated/illiterate populations.

Evaluation of trauma care in a developing country highlighted by a major aircraft accident.

The aim of this study was to evaluate the day-to-day trauma care in a developing country highlighted by a major accident. In this accident, early management was not carried out according to triage principles. Scene mortality and in-hospital mortality were 72% (n = 55) and 14% (n = 3), respectively. Overall mortality rate was 76%. Five survivors were minor wounded. Three laparotomies, one thoracotomy and three tube thoracostomies were performed in the acute phase. Skeletal injuries, mainly rib fractures (43.3%) and haemothorax (10.8%), were the most frequent pathologies seen. One liver laceration, one splenic rupture, one intraabdominal bleeding due to rupture of mesenteric vessels, two major cranial traumas and an abruptio placenta were the other pathologies. The missed injury rate in this accident was 16% (n = 6). It is concluded that the missed injuries in this incident reflect the inadequacy of trauma care in the rural area of the developing country.

Sexual behaviour in developing countries: implications for HIV control.

OBJECTIVE: To provide basic information on pre- and extramarital sex in the general population and other factors related to HIV transmission. DESIGN: Cross-sectional household survey in 18 countries of the developing world, mainly in Africa and Asia. RESPONDENTS: Representative samples of 1300-6995 individuals aged 15-49 years, interviewed in 1989-1993. METHODS: Face-to-face interviewing. RESULTS: We observed a huge variability between study sites, with the proportion of men reporting sexual contact outside regular partnerships in the last year ranging from 4 to 47%. Contacts with sex workers range from 1 to 25%. Women were much less likely to report non-marital sex than men. CONCLUSIONS: This first cross-cultural attempt to examine aspects of sexual lifestyles suggests that broad generalizations about multiple-partner sexual networking in particular regions are misleading. Gender, marital status, age and a few other demographic correlates were disclosed as powerful determinants of sexual behaviour, although the strength of associations varied greatly between specific locations. Condom use was very low in most study sites.
