ABSTRACT: Objectives: To propose a methodological path to investigate the coverage and information filling of maternal-infant deaths recorded in the Ministry of Health's Mortality Information System for regional spaces. Methods: Four steps were proposed: 1) Assessment of the completeness of the maternal and child variables, which was measured using the deterministic linkage technique between the Mortality Information System (Sistema de Informações sobre Mortalidade – SIM) and the Live Birth Information System (Sistema de Informações sobre Nascidos Vivos – SINASC); 2) Application of the multiple imputation technique to achieve the total filling of the missing information of the variables; 3) Estimation of death coverage; 4) The Unknown Variable Information Index (Índice de Informação Desconhecida da Variável – IIDV) was measured, which represents the combined effect of data completeness and coverage of deaths. The proposal of the methodological path was exemplified for neonatal deaths in the municipalities of Paraíba that are part of the new classification proposed by the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística – IBGE), as adjacent rural areas, in three triennium periods from 2009 to 2017. Results: The percentage of matching records was 45%. Most of the variables had a percentage of non-completion below 10% and around 17% for the mother's education. Coverages ranged from 75 to 83%. The IIDV for all variables was between 21 and 36% after the linkage. Conclusion: The path of the methodological proposal proved to be effective, which can be replicated to other regions, and can be extended to other categories of deaths such as post-neonatal. The combination of the proposed procedures demands low operating costs and their uses are relatively simple to be applied by the managers and technicians of the vital statistics information systems.

The infant mortality rate (IMR) among single and twin births from 1999 to 2008 was analyzed using Japanese Vital Statistics. The IMR was 5.3-fold higher in twins than in singletons in 1999 and decreased to 3.9-fold in 2008. The reduced risk of infant mortality in twins relative to singletons may be related, partially, to survival rates, which improved after fetoscopic laser photocoagulation for twin — twin transfusion syndrome. The proportion of neonatal deaths among total infant deaths was 54% for singletons and 74% for twins. Thus, intensive care of single and twin births may be very important during the first month of life to reduce the IMR. The IMR decreased as gestational age (GA) rose in singletons, whereas the IMR in twins decreased as GA rose until 37 weeks and increased thereafter. The IMR was significantly higher in twins than in singletons from the shortest GA (<24 weeks) to 28 weeks as well as ≥38 weeks, whereas the IMR was significantly higher in singletons than in twins from 30 to 36 weeks. As for maternal age, the early neonatal and neonatal mortality rates as well as the IMR in singletons were significantly higher in the youngest maternal age group than in the oldest one, whereas the opposite result was obtained in twins. The lowest IMR in singletons was 1.1 per 1,000 live births for ≥38 weeks of gestation and heaviest birth weight (≥2,000 g), while the lowest IMR in twins was 1.8 at 37 weeks and ≥2,000 g.

Tertiary Center

Background: Safe motherhood and child survival have always been a concern for the policymakers but perinatal mortality, especially stillbirths, have not received due attention. There are 5.9 million perinatal deaths worldwide, almost all of which occur in developing countries. Stillbirths account for over half of all perinatal deaths. This study was aimed to determine perinatal mortality rate and related obstetrics risk factors. Perinatal mortality is only a tip of the iceberg, morbidity being much higher. Vital statistics obtained through this study may serve an important source of information to guide the public health policy makers and health care providers in future.Methods: Present observational study was undertaken in a tertiary center to look into various maternal factors and possible cause of perinatal death. All perinatal deaths including stillbirths (SBs) and early neonatal deaths (ENNDs) within 0-7 days of birth after 28 weeks of gestation were analysed. The data was collected through a pre-designed proforma.Results: Perinatal mortality is 66.27/1000 births in our centre, where 37% were intrauterine deaths, 34% were neonatal deaths and 29% were still births. Preterm, pregnancy induced hypertension; abruptio placentae remain the most important factors for perinatal loss.Conclusions: One of the reasons for high perinatal mortality in tertiary centres is because of poor antenatal care at peripheral centres and late referrals. Early detection of obstetric complications and aggressive treatment is one of golden rule to reduce perinatal loss.

The Impact

ObjectiveGuidelines recommend individual decision making on resuscitating infants of 22–24 weeks’ gestational age (GA) at birth. When the decision not to resuscitate is made, infants would likely die soon after delivery, and under some circumstances such neonatal deaths may be registered as stillbirths occurring during delivery (intrapartum stillbirth). Thus we assessed whether socioeconomic factors are associated with peridelivery deaths (during or within 1 hour of delivery) of infants delivered at 22–24 weeks’ gestation.MethodsWe analysed 14 726 singletons of 22–24 weeks’ GA using the 2003–2011 Japanese vital statistics, and assessed how maternal characteristics influence risk of peridelivery death as well as intrauterine fetal death (IUFD) and death after 1 hour of age until 40 weeks postmenstrual age.ResultsLiving in a municipality with low-average income (lowest tertile (risk ratio 1.32, 95% CI 1.20 to 1.44), middle tertile (risk ratio 1.08, 95% CI 0.98 to 1.19)), younger maternal age (age <20 (risk ratio 1.43, 95% CI 1.17 to 1.75), age 20–34 (risk ratio 1.14, 95% CI 1.03 to 1.27)) and having previous live births (risk ratio 1.08, 95% CI 1.01 to 1.17) increased risk of peridelivery deaths, but did not increase risk of IUFD or deaths after 1 hour of age. Peridelivery death was twice as likely to occur in births to multiparous teenage mothers in a low-income municipality, compared with those of older primiparous mothers in a wealthier municipality.ConclusionsSocioeconomic factors substantially influence whether births of 22–24 weeks’ GA survive delivery and the first hour of life. Such disparities may reflect the impact of socioeconomic situations on decision making for resuscitation.

The Impact

Abstract This paper measures the impact of midwifery-promoting public policies on maternity care in the United States, using national Vital Statistics data on births spanning 1989-1999. State laws mandating insurance coverage of midwifery services are associated with an 18-percentage rise in midwife-attended births. The laws did not decrease rates of cesarean deliveries or lead to consistent effects on maternal mortality or Apgar scores. They did, however, lead to a statistically significant drop in neonatal deaths. Divergence between OLS and natural experiment estimates suggests that women are selecting into provider groups based on unobserved preferences and health.

The existence of a malformation in a fetus is not often associated with abnormalities of pregnancy or labor. The chief concern of the obstetrician is in counseling the parents concerning future childbearing. Malformations were reported by the National Office of Vital Statistics as responsible for 4.4 neonatal deaths per 1000 live births during the first 3 months of 1950. They accounted for 24% of the deaths of infants weighing over 2500 gm; 7% of the deaths of infants weighing under 2500 gm; that were born in the U.S. during this interval. In a study of 5000 consecutive births at the Chicago Lying-in Hospital in 1951 and 1952, 210 surviving infants were found to have certain conditions considered to be malformations. It was thought that not more than 10% of these infants, or 4.2 per 1000 births, would be handicapped by the malformations. Coupling this with the deaths and stillbirths occurring during the same period gives a total of 10.6 per 1000 births. Thus about 1% of reported births are infants with lethal or handicapping malformations which can be diagnosed at or soon after birth. Lethal malformations involved the central nervous system more often than any other part of the body, with anencephaly the most common single anomaly. Cardiac malformations were second, with those of the gastrointestinal and genitourinary tracts about equal in third and fourth places. Malformations occur more commonly in males than females and in white than non-white and in the children of women who are near the beginning or end of the age when reproduction is possible. Genetic disturbances can rarely be shown to be the cause of lethal malformations.

Cross-sectional study, whose data source was the fetal death investigation form, in less than a year, filled out by Recife’s surveillance (PE). Then, a comparison proceeded between fetal and premature neonatal preventable death groups, utilizing the Pearson’s Chi-square test, with a=5%. From 117 analyzed deaths, 94 (80.3%) were fetal. The evaluation of healthcare presented failures in 95.6% of perinatal deaths, emphasizing the assistance to prenatal, with failures of 75.6% of fetal and 90% in premature neonatal deaths. Deaths reducible by adequate assistance for women during pregnancy were the main preventable group (64.1%). There were deficiencies in the assistance in almost all deaths. The comparison among avoidable perinatal deaths allowed the evaluation of care quality and may enable contributions towards the elaboration of reduction strategies.Descriptors: Perinatal Mortality, Maternal and Child Health, Vital Statistics, Public Health Surveillance. Vigilancia del óbito evitable: comparación entre fetal y neonatal precozResumen: Comparar características sociodemográficas, de auxílio social y epidemiológicas de óbitos fetales y neonatales precoces evitables investigados.

EUROCAT is a European network of population-based congenital anomaly (CA) registries. Twenty-one registries agreed to participate in the EUROlinkCAT study to determine if reliable information on the survival of children born with a major CA between 1995 and 2014 can be obtained through linkage to national vital statistics or mortality records. Live birth children with a CA could be linked using personal identifiers to either their national vital statistics (including birth records, death records, hospital records) or to mortality records only, depending on the data available within each region. In total, 18 of 21 registries with data on 192,862 children born with congenital anomalies participated in the study. One registry was unable to get ethical approval to participate and linkage was not possible for two registries due to local reasons. Eleven registries linked to vital statistics and seven registries linked to mortality records only; one of the latter only had identification numbers for 78% of cases, hence it was excluded from further analysis. For registries linking to vital statistics: six linked over 95% of their cases for all years and five were unable to link at least 85% of all live born CA children in the earlier years of the study. No estimate of linkage success could be calculated for registries linking to mortality records. Irrespective of linkage method, deaths that occurred during the first week of life were over three times less likely to be linked compared to deaths occurring after the first week of life. Linkage to vital statistics can provide accurate estimates of survival of children with CAs in some European countries. Bias arises when linkage is not successful, as early neonatal deaths were less likely to be linked. Linkage to mortality records only cannot be recommended, as linkage quality, and hence bias, cannot be assessed.

International Comparability

The annual summary of vital statistics for 1971 was noted in the December 1972 issue. I am confused as to the method of reporting newborn deaths. The recently revised Standards and Recommendations, Hospital Care of Newborn Infants handbook recommends reporting a perinatal death rate for international comparability. Stillbirths after 28 weeks and neonatal deaths under seven days* are used as a more relative means of assessing conditions surrounding birth. The following formula is used to calculate the perinatal death rate:
