Intrapartum-related birth asphyxia in South Africa--lessons from the first national perinatal care survey.

BACKGROUND: The recent amalgamation of data by users of the Perinatal Problem Identification Programme (PPIP) throughout South Africa has culminated in the publication of the Saving Babies report. OBJECTIVES: To determine the absolute rate of death from intrapartum-related birth asphyxia, and the contribution of intrapartum-related asphyxia to total perinatal mortality in South African hospitals, and to identify the primary obstetric causes and avoidable factors for these deaths. METHODS: The amalgamated PPIP data for the year 2000 were obtained from 27 state hospitals (6 metropolitan, 12 town and 9 rural) in South Africa. In PPIP-based audit, all perinatal deaths are assigned primary obstetric causes and avoidable factors, and these elements were obtained for all deaths resulting from intrapartum-related birth asphyxia. RESULTS: There were 123,508 births in the hospitals surveyed, with 4,142 perinatal deaths among infants > or = 1,000 g, giving a perinatal mortality rate of 33.5/1,000 births. The perinatal mortality rate from intrapartum-related birth asphyxia was 4.8/1,000 births. The most frequent avoidable factors were delay by mothers in seeking attention during labour (36.6%), signs of fetal distress interpreted incorrectly (24.9%), inadequate fetal monitoring (18.0%) and no response to poor progress in labour (7.0%). The perinatal mortality rates for metropolitan, town, and rural areas were 30.0, 39.4 and 30.9/1,000 births respectively. The contribution of intrapartum-related birth asphyxia to perinatal mortality in these areas was 10.8%, 16.7% and 26.4% respectively. CONCLUSION: The high rates of perinatal death from intrapartum-related birth asphyxia in South Africa are typical of those in underdeveloped countries, with the most serious deficiencies in rural areas. Most of these deaths are avoidable and the reduction of these rates presents an important challenge to providers of perinatal care in this country. Areas worthy of research and action include provision of mothers' waiting facilities in rural regions, improvements in fetal monitoring, partogram-based labour management, and the establishment of midwifery staffing norms for South African labour units.

PPP insights in South Africa.

After functioning for some time in an increasingly regulated and structured environment in dealing with the private sector in South Africa, it was important to Government, to carefully review the terminology used in this evolving playing field. As the definitions and mechanisms impacting on this form of interaction became clear, it was essential to find a broader definition to encompass all forms of commercial intervention between the two sectors. In preparation for the first South African National Health Summit during 2001, the term public private interaction became a general term used in this context. In the South African healthcare sectors this term is used specifically to indicate that all forms of interaction between the two sectors should be considered, rather than merely focussing on specific Public Private Partnerships (PPPs), that have a much more narrow definition. Recent health policy documents in South Africa all stress four key goals--equity, coherence, quality of care and efficiency--which provide a useful basis for decision-making about PPIs. The range of public-private interactions that may support or constrain the South African health system's development are set within the overall public/private mix of the country. In developing an equitable, efficient, coherent and high quality health system in South Africa, there is considerable potential for constructive engagement (collaboration and co-operation) between the public and the private health care sectors. Both sectors should embrace this opportunity and therefore it is useful to propose some basic guidelines for engagement based on the vision and goals of the national health system. In deciding whether or not to pursue any new PPI within the health sector, or in evaluating whether an existing PPI should continue or be revised, it is necessary to assess its merits in relation to the achievement of health system goals.

Fetal alcohol syndrome--South Africa, 2001.

Fetal alcohol syndrome (FAS) is caused by maternal alcohol use during pregnancy and is one of the leading causes of preventable birth defects and developmental disabilities. The FAS phenotype is characterized by a combination of facial dysmorphic features, growth retardation, and central nervous system (CNS) abnormalities. State-based estimates of the prevalence of FAS in the United States vary from 0.3 to 1.5 per 1,000 live-born infants. Recently, the highest prevalence of FAS worldwide was reported among first-grade children in a wine-growing region in the Western Cape province of South Africa. Investigators for the National Institutes of Alcoholism and Alcohol Abuse (NIAAA) reported a FAS prevalence of 40.5 to 46.4 per 1,000 children aged 5-9 years in one community in Western Cape. To determine whether FAS was associated exclusively with the wine-growing region in Western Cape or was more endemic in other areas of the country, CDC, in collaboration with the University of Witwatersrand and the Foundation for Alcohol Related Research in Johannesburg, South Africa, conducted a prevalence study in Gauteng province and is developing ongoing surveillance and prevention activities. This report summarizes the findings of the study, which indicate a high prevalence of FAS among first-grade children in four nonwine-growing communities around Johannesburg. Because South Africa has limited resources and many competing health problems (e.g., human immunodeficiency virus/acquired immunodeficiency syndrome, tuberculosis, and sexually transmitted diseases), integrating prenatal alcohol-exposure prevention activities with existing prevention programs should be explored.

Why babies die--a perinatal care survey of South Africa, 2000-2002.

OBJECTIVE: To identify the major causes of perinatal mortality in South Africa. SETTING: Seventy-three state hospitals throughout South Africa representing metropolitan areas, cities and towns and rural areas. METHOD: Users of the Perinatal Problem Identification Programme (PPIP) amalgamated their data to provide descriptive information on the causes of perinatal death and the avoidable factors, missed opportunities and substandard care in South Africa. RESULTS: A total of 8,085 perinatal deaths among babies weighing 1,000 g or more were reported from 232,718 births at the PPIP user sites. The perinatal mortality rates for the metropolitan, city and town, and rural groupings were 36.2, 38.6 and 26.7/1,000 births, respectively. The neonatal death rate was highest in the city and town group (14.5/1,000 live births) followed by the rural and metropolitan groups (11.3 and 10.0/1,000 live births respectively). The low birth weight rate was highest in the metropolitan group (19.6%), followed by the city and town group (16.5%) and the rural group (13.0%). The most common primary cause of perinatal death in the rural group was intrapartum asphyxia and birth trauma (rate 6.92/1,000 births) followed by spontaneous preterm delivery (5.37/1,000 births). The most common primary cause of death in the city and town group was spontaneous preterm delivery (6.79/1,000 births) followed by intrapartum asphyxia and birth trauma (6.21/1,000 births) and antepartum haemorrhage (5.7/1,000 births). The metropolitan group's most common primary causes were antepartum haemorrhage (7.14/1,000 births), complications of hypertension in pregnancy (5.09/1000 births) and spontaneous preterm labour (4.01/1,000 births). Unexplained intrauterine deaths were the most common recorded primary obstetric cause of death in all areas. Complications of prematurity and hypoxia were the most common final causes of neonatal death in all groups. CONCLUSION: Intrapartum asphyxia, birth trauma, antepartum haemorrhage, complications of hypertension in pregnancy and spontaneous preterm labour account for more than 80% of the primary obstetric causes of death.

Hunger and malnutrition: the determinant of development: the case for Africa and its food and nutrition workers.

Hunger and malnutrition in Africa have been on the increase since 1960's reaching a climax in the 1980's when over 150 million people were affected by one form or another. Methods so far used to solve the problem do not seem to succeed, but the scientists and leaders in Africa could now take the opportunity to consider and act on the problem in their own way. The formation of an African food and nutrition group to work with others on the problems, could give an impetus to this kind of initiative. A call is made to all African food and nutrition workers to combine efforts to harness Africa resources, which have not been fully utilized in solving the problem.

The burden of disease from neonatal mortality: a review of South Asia and Sub-Saharan Africa.

OBJECTIVE: To assess the burden of neonatal mortality in two developing regions. DESIGN: Review of secondary data collated through literature review. SETTING: Community and facility based studies and national health surveys. POPULATION: Neonatal (<28 days) population of South Asia and Sub-Saharan Africa. METHODS: Data on neonatal mortality were gathered from peer-reviewed literature, reports of the Demographic and Health Surveys and websites of country-based organisations. The base year for this study is 1995. For each country, a weighted mean neonatal mortality rate was calculated and the total number of neonatal deaths estimated. Country data were summarised over each region to estimate annual regional neonatal deaths and rates. The burden of disease from neonatal mortality was determined using a summary measure of health--healthy life years. MAIN OUTCOME MEASURES: Numbers of deaths and healthy life years (HeaLYs). RESULTS: Neonatal mortality rate for South Asia ranged from 41.9 to 56.9 per 1000 live births for 1995. Sri Lanka was an exception with a neonatal mortality rate between 16.3 and 18.6 per 1000 live births. The estimated regional neonatal mortality rate for South Asia was 46.27 per 1000 live births for 1995. There was a significant lack of data from Sub-Saharan Africa, resulting in highly variable neonatal mortality rates, ranging from 13 per 1000 live births in Kenya to 108 per 1000 live births in Senegal. The mean regional neonatal mortality for Sub-Saharan Africa for 1995 was estimated at 38.8 per 1000 live births. CONCLUSION: The burden of neonatal mortality in only these two regions of the developing world represents more than 2 million annual deaths. A call for greater investments in neonatal research and health programs is a logical extension to this review of evidence.

A comparison of attitudes of medical students in England and in South Africa towards patients with life-limiting illness.

All medical schools in the U.K. now include teaching in palliative care in the undergraduate curriculum, and this is mirrored in Europe and the U.S.A. In South Africa, however, palliative care education and provision are not widely available. An increasing number of medical and nursing staff are invited to teach palliative care in other countries. Such teaching should, however, take into account the cultural attitudes the students have towards the care of patients with a chronic or terminal illness. Nineteen statements on attitudes were constructed, and medical students in Leicester, U.K., and in Medunsa, South Africa, were invited to respond to them using a 10-point Likert scale. The questionnaire was distributed before either cohort of students had received any teaching in this area. Students in South Africa were significantly more likely to want to work in a speciality where most patients were likely to be cured (p < 0.001) and significantly less likely to believe that caring for dying patients could be rewarding (p < 0.001). South African medical students had significantly fewer positive attitudes than had their U.K. counterparts toward patients being informed of a terminal prognosis (p < 0.001). This study indicates that cultural differences between medical students may have an effect on the teaching of care for patients with life-limiting illness. This has relevance for curriculum delivery, especially when professionals are invited to teach or develop material on palliative care for other countries.

Cardiac involvement in HIV-infected people living in Africa: a review.

The primary objective of this study was to review and summarise the literature on the spectrum and management of cardiac disease in HIV-infected people living in Africa. We searched MEDLINE (January 1980 to February 2003), reference lists of papers, and reviews on the subject, and contacted experts working in the field for information on relevant references. The review was limited to papers that were published in peer-reviewed journals and indexed on MEDLINE. Seventeen of the 21 studies identified met the inclusion criteria for analysis. The studies confirmed that cardiac abnormalities are more common in HIV-infected people, compare to normal controls, and that about half of hospitalized patients and a significant proportion of patients followed up over several years develop cardiac abnormalities. The commonest HIV-related cardiac abnormalities were cardiomyopathy and pericardial disease. Tuberculosis was the major cause of large pericardial effusion in Africa. Myocarditis was the commonest pathological abnormality in HIV-associated cardiomyopathy, and non-viral opportunistic infections such as toxoplasmosis and cryptococcosis may account for up to 50% of cases of HIV-associated cardiomyopathy in Africa. Echocardiography is indicated in HIV-positive patients with cardiac symptoms or signs. If cardiomyopathy or pericardial disease is identified, further investigation must be considered to exclude potentially treatable opportunistic infections. Further research in large numbers of patients is needed to determine the value of endomyocardial biopsy in the management of patients with HIV-associated cardiomyopathy, and to establish the place of adjuvant steroids in the treatment of HIV-associated tuberculous pericarditis.

Initial burden of disease estimates for South Africa, 2000.

BACKGROUND: This paper describes the first national burden of disease study for South Africa. The main focus is the burden due to premature mortality, i.e. years of life lost (YLLs). In addition, estimates of the burden contributed by morbidity, i.e. the years lived with disability (YLDs), are obtained to calculate disability-adjusted life years (DALYs); and the impact of AIDS on premature mortality in the year 2010 is assessed. METHOD: Owing to the rapid mortality transition and the lack of timely data, a modelling approach has been adopted. The total mortality for the year 2000 is estimated using a demographic and AIDS model. The non-AIDS cause-of-death profile is estimated using three sources of data: Statistics South Africa, the National Department of Home Affairs, and the National Injury Mortality Surveillance System. A ratio method is used to estimate the YLDs from the YLL estimates. RESULTS: The top single cause of mortality burden was HIV/AIDS followed by homicide, tuberculosis, road traffic accidents and diarrhoea. HIV/AIDS accounted for 38% of total YLLs, which is proportionately higher for females (47%) than for males (33%). Pre-transitional diseases, usually associated with poverty and underdevelopment, accounted for 25%, non-communicable diseases 21% and injuries 16% of YLLs. The DALY estimates highlight the fact that mortality alone underestimates the burden of disease, especially with regard to unintentional injuries, respiratory disease, and nervous system, mental and sense organ disorders. The impact of HIV/AIDS is expected to more than double the burden of premature mortality by the year 2010. CONCLUSION: This study has drawn together data from a range of sources to develop coherent estimates of premature mortality by cause. South Africa is experiencing a quadruple burden of disease comprising the pre-transitional diseases, the emerging chronic diseases, injuries, and HIV/AIDS. Unless interventions that reduce morbidity and delay morbidity become widely available, the burden due to HIV/AIDS can be expected to grow very rapidly in the next few years. An improved base of information is needed to assess the morbidity impact more accurately.

Adequacy and efficiency of nursing staff in a child-welfare-clinic at Umtata General Hospital, South Africa.

BACKGROUND: South Africa has a serious shortage of human and financial resources to provide primary healthcare services especially in the historically under-served areas. It is a tedious task to carry out healthcare delivery for the masses without rationalizing human resources in the form of re-allocation and re-deployment of healthcare personnel. This study aimed to establish the level of adequacy and efficiency of nursing staff in the former Transkei region. The study was carried out in the child and family welfare clinic of the Umtata General Hospital. OBJECTIVE: To assess adequacy and efficiency of nursing staff in a child welfare clinic. METHOD: This was a retrospective study. The workload of two nurses allocated to the child welfare clinic at Umtata General Hospital South Africa was calculated based on the patient numbers and hours of work per week. Calculations excluded time breaks for tea, lunch and annual leave. This work load was compared to the norms of standard examination time that is 12 minutes per patient obtained from the sub directorate of Natalia Office of the Department of Health. Information regarding number of patients attended to by the nurses and their disease conditions was obtained from retrospective review of hospital records. RESULTS: While each nurse was on duty for 8 hours per day each had only 6 reproductive hours. The two nurses examined only 310 patients giving staff utilization of 2.46% (i.e. 310/12600) and adequacy of staff of 0.0492 or 310/6300. CONCLUSION: There is under-utilization of the staff in Umtata General Hospital, South Africa. RECOMMENDATION: To increase utilization of the nurses a process of sharing and merging with a clinic or a ward with similar type of work is recommended.

Huntington's chorea in the Cape coloured community of South Africa.

Huntington's chorea is a grave genetic neurological disorder which appears to be a more serious problem in South Africa than has generally been recognized. The minimum prevalence of the disease in the Cape Coloured is 3,5/100 000 of the population. Sixteen per cent of patients were younger than 20 years at the time of onset of the disease. This is among the highest incidence of juvenile Huntington's chorea in the world. The gene for Huntington's chorea has been in South Africa for 300 years. It was first introduced into this country from Holland in the middle of the 17th century and then later from England in the middle and end of the 19th century. The number of affected individuals appears to be on the increase in South Africa. Unfortunately, at present, no methods are available for effective control of this disorder.

HIV antiretroviral drug resistance in Africa.

Highly active antiretroviral therapy (HAART) has dramatically reduced mortality and morbidity in HIV-infected persons in developed countries. Although the use of HAART remains limited in Africa, there are global efforts to make available these drugs to several million HIV-infected persons on the continent. In this review we examine the impact of HIV genetic diversity on the occurrence of drug-resistance mutations among non-B subtypes, and discuss the implication of resistant strains in programs aimed at implementing antiretroviral treatment (ART) in Africa, with respect to factors that may favor the occurrence of treatment-acquired drug-resistant viruses, ways to monitor for drug resistance, and strategies to limit its occurrence. We assert that antiretroviral drug resistance is an inevitable consequence when providing long-term treatment, and should not be seen as a limitation of providing antiretrovirals to patients in resource-poor settings, but rather a necessary challenge to be incorporated into the rational design of programs that provide ART in Africa.

Urbanization in sub-saharan Africa and implication for malaria control.

Malaria not only remains a leading cause of morbidity and mortality, but it also impedes socioeconomic development, particularly in sub-Saharan Africa. Rapid and unprecedented urbanization, going hand-in-hand with often declining economies, might have profound implications for the epidemiology and control of malaria, as the relative disease burden increases among urban dwellers. Reviewing the literature and using a modeling approach, we find that entomologic inoculation rates in cities range from 0 to 54 per year, depending on the degree of urbanization, the spatial location within a city, and overall living conditions. Using the latest United Nations figures on urbanization prospects, nighttime light remotely sensed images, and the "Mapping Malaria Risk in Africa" results on climate suitability for stable malaria transmission, we estimate that 200 million people (24.6% of the total African population) currently live in urban settings where they are at risk of contracting the disease. Importantly, the estimated total surface area covered by these urban settings is only approximately 1.1-1.6% of the total African surface. Considering different plausible scenarios, we estimate an annual incidence of 24.8-103.2 million cases of clinical malaria attacks among urban dwellers in Africa. These figures translate to 6-28% of the estimated global annual disease incidence. Against this background, basic health care delivery systems providing early diagnosis and early treatment and preventive actions through mother and child health programs and the promotion of insecticide-treated bed nets for the rapidly growing numbers of the urban poor must be improved alongside well-tailored and integrated malaria control strategies. We propose environmental management and larviciding within well-specified productive sites as a main feature for such an integrated control approach. Mitigation of the current burden of malaria in urban African settings, in turn, is a necessity for stimulating environmentally and socially sustainable development.

Tying up lions: multilateral initiative on malaria communications: the first chapter of a malaria research network in Africa.

"When spider webs unite, they can tie up a lion" (Ethiopian folk adage). The Multilateral Initiative on Malaria Communications Network (MIMCom) facilitates a new way of doing research in Africa and African scientists' participation in the international scientific community. The MIMCom supports full access to the Internet and the resources of the WorldWide Web at 19 research sites in 11 African countries. Furthermore, the MIMCom project comprises two websites: one includes links to resources, databases, and publications as well as a document delivery service for full text journal articles, and the other is a research agenda specific website with a server for a research network desiring to share raw data. Other important components of MIMCom are training and evaluation components. The MIMCom was conceived in 1997 by African researchers and has been designed, implemented, and overseen by the U.S. National Library of Medicine in collaboration with partners in Africa, the United States, and the United Kingdom. This project demonstrates clearly that it can make a positive difference in the functioning of remote research sites in Africa, in terms of site growth and productivity and in the professional lives of individual researchers. This report reviews the project's background, methods of operation with an emphasis on local needs and priorities, cost effectiveness, and local responsibility; results focusing on a technical network; documentation of the system and two-way exchange of information; the MIMCom website; a network approach to research; and financial sustainability. The report concludes with summaries of evaluations by an independent panel, the Multilateral Initiative on Malaria Secretariat, and the U.S. National Library of Medicine.

Are multilateral malaria research and control programs the most successful? Lessons from the past 100 years in Africa.

Multilateral malaria research and control programs in Africa have regained prominence recently as bilateral assistance has diminished. The transnational nature of the threat and the need for inspired leadership, good coordination, and new discoveries to decrease the impact of the disease has led to the founding of the Multilateral Initiative on Malaria, the Roll Back Malaria Project, Global Fund for HIV, Tuberculosis and Malaria (Global Fund), the Medicines for Malaria Venture, and the Malaria Vaccine Initiative, among other groups. Historically, the most striking feature of malaria control and elimination activities was the connectedness and balance between malaria research and control especially, from 1892 to 1949. A combination of scientific originality, perseverance in research, integrated approaches, and social concern were the keys for success. The elimination of Anopheles gambiae from Upper Egypt in 1942 using integrated vector control methods is a prime example of malaria control during the first half of the 20th century where those factors were brought together. After 1949, there were three decades of great optimism. Four notable landmarks characterized this period: the Kampala Conference in 1950; the Global Malaria Eradication Program beginning in 1955; the primary health care strategies adopted by most African States after attaining their political independence in the 1960s, and accelerating in the 1980s; and creation of the Special Program in Training and Research in Tropical Diseases at the World Health Organization in 1975. The initial highly encouraging operational results, largely obtained in temperate or subtropical areas where transmission was unstable, engendered undue expectations for the success of identical antimalarial measures elsewhere. Many were convinced that the eradication was in sight, such that support for malaria research virtually ceased. Young, bright scientists were discouraged from seeking a career in a discipline that appeared to soon become superfluous. It took more than three decades to modify antimalarial strategies and to rehabilitate long-term control as an intermediate objective. In Africa, although multilateral malaria programs have grown over the past half century and proved the most successful, fragmentation of co-ordination remains and is a major challenge. The proliferation of malaria programs in the late 1990s has brought substantial additional funds and expertise. However, excessive funding competition and failure of different programs to collaborate has resulted in poor communication and duplication of activities. The capacities of the African nations to conduct high-quality research and to coordinate control efforts are in great jeopardy. There is an urgent need for a non-partisan umbrella organ to coordinate and facilitate the network of alliances and programs in malaria research and control in Africa.

The natural history of HIV-1 and HIV-2 infections in adults in Africa: a literature review.

About 30 million people in Africa are estimated to be living with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), yet data about the natural history of infection on the continent are sparse. We reviewed the literature on the natural history of HIV-1 and HIV-2 infections among African adults. Only one study, conducted in rural Uganda, has reported on survival from the time of HIV-1 seroconversion: the median was 9.8 years, which is similar to that reported in developed countries in the early stages of the epidemic and consistent with the findings from the follow-up of individuals identified by serological testing during community-based prevalence studies from Africa. Progression to symptomatic disease was faster in Uganda than in developed countries, due largely to the high background level of morbidity. Various studies suggest that people infected with HIV-2 survive longer and the course of the disease is possibly more variable than in people infected with HIV-1. However no studies have investigated survival from time of seroconversion among people infected with HIV-2. The majority of patients in hospital in Africa with either HIV-1 or HIV-2 have the clinical features of AIDS just before they die, and many are severely immunosuppressed. This is similar to the situation in developed countries before the introduction of highly active antiretroviral therapy (HAART). Potentially preventable infections are the leading causes of death among individuals infected with HIV-1. Prophylactic regimens and better treatments could have some effect on survival, but major improvements in life expectancy will require HAART.

Cancer control in Africa: a call for action.

Cancer is an emerging public health problem in Africa especially with increasing frequency of HIV-associated malignancies and exposure to environmental carcinogens. This review attempts to highlight steps that can be taken to achieve effective control programmes in low-resource areas of Africa. The author reviews the areas of importance in cancer control programmes based on local experience. To implement cancer control programmes, steps must be taken to improve the data collection on incidence and trends of common cancers with the establishment of local cancer registries. There is the necessity to increase the level of awareness of the population about common cancers, to dispel the cultural taboos and myths, and teach basic preventive health measures. These can be achieved by well-organized sustained educational programmes extended to the grass-roots with community participation. The training of personnel at community level to recognize the early signs and symptoms coupled with provision of primary health care facilities and basic sustained well-planned referral system will be necessary to accommodate the fall-out of educational programmes and anti-cancer campaign. The integration of cancer control activities into the existing health care structure would make it easier to sustain these programmes. The cost-effectiveness of prevention and early diagnosis of cancer cannot be over-emphasized in Africa. With government investment in national health and provision of facilities for early diagnosis and treatment, effective cancer control can be achieved.

Recent paleoanthropological excavations of in situ deposits at Makapansgat, South Africa--a first report.

The Makapansgat Limeworks is a significant Pliocene site both for its sample of 35 hominin fossils as well as its wealth of fossil fauna. The lithological and paleontological successions reveal local environmental changes that are important for understanding the context of hominin evolution in southern Africa. Yet most of the site's fossils were found in dumps left behind by quarry operations, and the paleoecological interpretations rest upon debatable assumptions about the original fossil provenience. We have recently initiated systematic paleoanthropological excavations at Makapansgat to recover well provenanced fossils in order to: 1) assess whether faunal successions are discernable in the Makapansgat sequence; 2) assist environmental interpretations of the site; 3) and potentially recover the oldest hominins in South Africa, roughly coincident with Australopithecus afarensis in East Africa. This paper presents a summary of our current paleoenvironmental research at the Limeworks and preliminary results of ongoing in situ excavations.
