[Validation of birth certificates based on data from a case-control study].

The information recorded on birth certificates was validated with data from a perinatal mortality case-control study, obtained from home interviews of mothers and hospital records for cases (early neonatal deaths) and controls. Sensitivity, specificity, and concordance were calculated for all variables and their estimated and real prevalence. The completeness of birth certificates was lowest for mother's parity and presence of congenital anomalies (records without information range from 23% to 31% for cases and controls). Birth certificates correctly identified low birth weight and type of delivery for cases and controls. Birth certificates showed high sensitivity and specificity to detect preterm births within cases. The number of preterm births was underestimated at 30.8% of the controls and 2.9% of the cases. Low maternal education was two times greater on birth certificates than in the mother's interview, for cases and controls. Completeness of birth certificates was higher in controls, but data quality was better in cases.

[Accidental home deliveries in southern São Paulo, Brazil].

OBJECTIVE: To identify the frequency, risks of fetal and early neonatal mortality and the determinants of accidental home deliveries. METHODS: A population-based case control study of fetal and early neonatal deaths was carried out in the southern area of São Paulo, Brazil. Data were collected through home interviews and hospital record reviews. The reasons reported by the mothers were obtained from interviews and risk factors for home delivery were obtained comparing home to hospital deliveries. Data were analyzed separately for fetal and early neonatal deaths and survivors. Odds ratios, 95% confidence intervals and Fisher's exact test were used in estimating risk factors and mortality risk. RESULTS: The 0.2% frequency of home deliveries was underestimated in the live births information system. After adjustment, it reached 0.4%, comparable to other urban areas in Europe. All home deliveries identified were accidental and were associated to an increased fetal and early neonatal mortality. Mothers' social conditions and pregnancy characteristics were associated to accidental home deliveries and these factors are different outcomes studied (fetal losses, early neonatal deaths and survivors). In 30%, mothers reported lack of available transportation to the hospital as a reason for home delivery. Failure of health services in identifying labor women and non-availability of emergency care contributed to accidental home deliveries. CONCLUSIONS: Though rare events in urban areas, accidental home deliveries should be of special concern to health services because they seem to be avoidable and imply in increased risk of death.

National maternal mortality ratio in Egypt halved between 1992-93 and 2000.

Two surveys of maternal mortality conducted in Egypt, in 1992-93 and in 2000, collected data from a representative sample of health bureaus covering all of Egypt, except for five frontier governorates which were covered only by the later survey, using the vital registration forms. The numbers of maternal deaths were determined and interviews conducted. The medical causes of death and avoidable factors were determined. Results showed that the maternal mortality ratio (MMR) had dropped by 52% within that period (from 174 to 84/100,000 live births). The National Maternal Mortality Survey in 1992-93 (NMMS) revealed that the metropolitan areas and Upper Egypt had a higher MMR than Lower Egypt. In response to these results, the Egyptian Ministry of Health and Population (MOHP) intensified the efforts of its Safe Motherhood programmes in Upper Egypt with the result that the regional situation had reversed in 2000. Consideration of the intermediate and outcome indicators suggests that the greatest effect of maternal health interventions was on the death-related avoidable factors "substandard care by health providers" and "delays in recognizing problems or seeking medical care". The enormous improvements in these areas are certainly due in part to extensive training, revised curricula, the publication of medical protocols and services standards, the upgrading of facilities, and successful community outreach programmes and media campaigns. The impact on the utilization of antenatal care (ANC) has been less successful. Other areas that remain problematic are inadequate supplies of blood, drugs and equipment. Although the number of maternal deaths linked to haemorrhage has been drastically reduced, it remains the primary cause. The drop in maternal mortality in the 1990s in response to Safe Motherhood programmes was impressive and the ability to tailor interventions based on the data from the NMMS of 1992-93 and 2000 was clearly demonstrated. To ensure the continuing availability of information to guide and evaluate programmes for reducing maternal mortality, an Egyptian national maternal mortality surveillance system is being developed.

The trend of maternal mortality in Egypt from 1992-2000: an emphasis on regional differences.

OBJECTIVE: To review factors contributing to a 52% drop in Egypt's maternal mortality ratio (MMR) per 100,000 live births from 174 in 1992-93 to 84 in 2000. METHODS: Data on maternal mortality were collected from all 27 governorates in Egypt between 1 January and 31 December 2000. This round of maternal mortality data is compared with the earlier nation wide maternal mortality study in 1992. Health care interventions that may account for the decrease were reviewed. RESULTS: MMR decreased by 51.7% nation wide. This decrease was greater in the less-developed parts of Upper Egypt (59%), than in Lower Egypt (30%). A multifaceted set of interventions were concentrated in Upper Egypt. The greatest decrease in maternal mortality was associated with the area of highest intervention, greatest need, and during the time period of the implementation of this program. There were increases in use of health services; use of modern contraceptives; hospital deliveries; and use of trained birth attendants. For most indicators, the changes were greater in Upper than Lower Egypt. CONCLUSION: Since 1992-93, efforts by the Government of Egypt and donors to improve access to and the quality and utilization of services can be linked to a greatly reduced MMR.

The Egypt National Perinatal/Neonatal Mortality Study 2000.

OBJECTIVES: To estimate stillbirth, perinatal (PMR) and neonatal mortality rates (NMR) in Egypt and to assign main causes of death. STUDY DESIGN: Data were collected from a representative sample of women who gave birth from 17,521 households which were included in the Egypt Demographic and Health Survey (EDHS) 2000. Comparisons were made between three systems for classifying causes of death. RESULTS: The NMR was 25 per 1000 live births (17 early and eight late). Half the deaths occurred in the first two days of life. Neonatal causes of death were pre-maturity (39%), asphyxia (18%), infections (7%), congenital malformation (6%) and unclassified (29%). The PMR was 34 per 1000 births, mainly attributed to: asphyxia (44%) and prematurity (21%). The revised Wigglesworth classification agreed well with the physicians except the panel attributed more deaths to infections (20%). The WHO verbal autopsy algorithm left 48% of deaths unclassified. CONCLUSIONS: Infant mortality in Egypt is showing an epidemiological transition with a significant decrease in mortality, resulting in a disproportionate percentage of deaths in the first week of life. Infant mortality in Egypt declined 64% from 124 per 1000 between 1974 and 1978 to 44 per 1000 between 1995 and 1999, the decline being greatest among older infants; 55% of all infant deaths occurred during the neonatal period. The neonatal mortality rate in this study was estimated to be 25 per 1000 live births.
