What is the infant mortality rate in South Africa? The need for improved data.

OBJECTIVE: To review recent infant mortality and birth registration data in South Africa and to investigate geographical differences. OUTCOME MEASURES: Estimates of infant mortality rates, proportion of births not registered, and proportion of births recorded in health services. METHODS: 1. Published infant mortality data for South Africa were collated. Demographic data from national household surveys (1993 and 1994 October Household Surveys and the 1993 Poverty Survey by the Southern African Labour and Development Research Unit (SALDRU) at UCT) were analysed using the indirect method developed by Brass. 2. Birth registration data were analysed and compared with the estimated number of births to identify regions with greater under-registration. The number of births recorded in the health services was analysed by province in order to assess and explore alternatives within health authorities that could complement the existing system. RESULTS: 1. Published estimates of infant mortality for the period from 1990 range from 40 to 71/1,000 births and estimates based on national household surveys conducted in this period from 11 to 81/1,000 births. 2. Completeness of birth registration in the nine provinces ranges from less than 10% in the Eastern Cape, North West and Northern Province to 60% in the Western Cape. An overall improvement from 19% to 60% could be achieved if births recorded through the health services were included in the vital registration system. CONCLUSIONS: The infant mortality rate in South Africa is not known with any certainty. The extent of completeness of the birth registration system was 19%, which indicates a need for urgent improvement in order to provide key health status indicators. This study indicates that there is some potential for improving the extent of birth registration if it could be facilitated through the health service. However, this alone would not achieve complete registration. RECOMMENDATIONS: Surveys will have to be relied upon until such time as routinely available statistics are accurate. The October Household Survey conducted annually by the Central Statistical Service as potentially an important source of health status information. It is imperative that either the design of the birth history questionnaire be improved or that it be replaced by a less frequent but more specialised demographic and health survey.

[Cerebral infarction--a general-medical problem].

A knowledge of events accompanying the acute coronary failure may help understanding the acute cerebral blood flow insufficiency leading to brain infarction. Cerebral blood flow should be treated as an integral part of the systemic blood circulation. It is of importance when the disease produces lesions to the vascular wall, and the brain looses its autoregulation functions. In such a situation every extracerebral disorders--even slight--may produce extensive lesions to nervous tissue. Therefore, the treatment of the acute cerebral circulation failure requires proper functioning of all factors which may affect hemodynamics and tissue metabolism. Duration of cerebral flow disorders plays an important role in the avoidance of unfavourable complications such as brain infarction. Therefore, every physician is obliged to undertake any possible actions preventing such complications.

[Brain stem insufficiency in acute ischemia and cerebral hemorrhage].

Consciousness disorders are closely related to the general dysfunction of the brain stem, and called by some authors brain stem insufficiency. To evaluate the degree of brain stem dysfunction, an original scale has been elaborated. Each group of brain stem functions are scored. Consciousness being the most important symptom of the brain stem insufficiency is scored about 50% in a 63-score scale. Scores are used to achieve the most objectivity in the clinical monitoring of the brain stem insufficiency. Its utility was examined in 75 patients with either ischemia or cerebral hemorrhage. Patients of both groups with severe insufficiency below 33 scores and persisting over 24 hours had no chance to survive. The authors suggest that the scores may successfully be used in the clinical monitoring of all disorders producing consciousness disturbances. Survival of patients with brain stem insufficiency in the course of cerebral ischemia or hemorrhage depends on the degree and duration of the brain stem insufficiency.

[Physical activity in acute cerebrovascular insufficiency].

It was noted that physical activity of 1052 patients hospitalized for the acute cerebral flow failure due to atheromatosis is an important indicator of the cerebral ischemia. Extension of ischemia evaluated on the basis of physical activity enables to foresee possible improvement and survival. Authors' own classification of physical activity may be helpful in the monitoring of cerebral flow failure therapy.
