Maternal mortality in England and Wales 1970-1985: an analysis by country of birth

"We need to be heard. We need to be seen": A thematic analysis of black maternal experiences of birthing and postnatal care in England within the context of Covid-19

OBJECTIVE

Inequalities for Black women within maternity settings are longstanding, with evidence showing higher mortality, complications and distress compared to White women. The Covid-19 pandemic saw unprecedented changes to maternity services, with emerging evidence highlighting a disproportionate impact on mothers from ethnically minoritized backgrounds. This uniquely positioned study explores Black women's experiences of services during Covid-19.

DESIGN

The study used a qualitative design with semi-structured interviews, data were analysed using reflexive thematic analysis.

SETTING

The study took was open to all in the UK, participants who took part were from England and were recruited via social media and community led organisations.

PARTICIPANTS

The study recruited 13 self-identifying Black women, aged between 23 and 41 who received maternity care across settings (NHS wards, home birth and birthing centre) across England.

MEASUREMENT AND FINDINGS

Three themes were generated from the study: 'The Ripples of Covid', 'Inequality within Inequality' and 'Conscientious Change for Maternity Systems', with sub-themes including the impact of regulations, the invisibility of pain and the importance of accountability. Alongside multiple layers of inequality and emotional labour for Black women, the study found connection and advocacy as facilitators of good care.

KEY CONCLUSIONS

Supporting existing research, Black women's experiences of maternity services during Covid-19evidence ongoing of structural racism within maternity provision, founded on stereotypes of strength and pain. Though moments of advocacy and connection, however, Covid-19 appeared exacerbated ongoing existing inequalities for Black women. Changes to service provision contributed to isolation, distress, and consequential inadequate care.

IMPLICATIONS FOR PRACTICE

The findings, generated by Black women, established important implications for practice and policy, including an emphasis on creating conscientious change of systems through a racialised lens, the importance of meaningful equity, representation, and the need for co-production alongside Black communities.

A systematic review of individual and ecological determinants of maternal mortality in the world based on the income level of countries

BACKGROUND

This systematic review was conducted to map the literature on all the existing evidence regarding individual and ecological determinants of maternal mortality in the world and to classify them based on the income level of countries. Such a systematic review had not been conducted before.

METHODS

We conducted an electronic search for primary and review articles using "Maternal Mortality" and "Determinant" as keywords or MeSH terms in their Title or Abstract, indexed in Scopus, PubMed, and Google with no time or geographical limitation and also hand searching was performed for most relevant journals. STROBE and Glasgow university critical appraisal checklists were used for quality assessment of the included studies. Data of the determinants were extracted and classified into individual or ecological categories based on income level of the countries according to World Bank classification.

RESULTS

In this review, 109 original studies and 12 review articles from 33 countries or at global level met the inclusion criteria. Most studies were published after 2013. Most literature studied determinants of low and lower-middle-income countries. The most important individual determinants in low and lower-middle-income countries were location of birth, maternal education, any delays in health services seeking, prenatal care and skilled birth attendance. Household-related determinants in low-income countries included improved water source and sanitation system, region of residence, house condition, wealth of household, and husband education. Additionally, ecological determinants including human resources, access to medical equipment and facilities, total fertility rate, health financing system, country income, poverty rate, governance, education, employment, social protection, gender inequality, and human development index were found to be important contributors in maternal mortality. A few factors were more important in higher-income countries than lower-income countries including parity, IVF births, older mothers, and type of delivery.

CONCLUSION

A comprehensive list of factors associated with maternal death was gathered through this systematic review, most of which were related to lower-income countries. It seems that the income level of the countries makes a significant difference in determinants of maternal mortality in the world.

Maternal mortality and severe morbidity in a migration perspective

Among migrants in high-income countries, maternal mortality and severe morbidity generally occur more frequently as compared to host populations. There is marked variation between groups of migrants and host countries, with much elevated risks in some groups and no elevated risk at all in others. Those without a legal resident permit are most vulnerable. A reason for these elevated risks could be a different risk profile in migrants, but risk factors are unevenly distributed and not always present. Another reason is substandard care, which is identified more frequently in migrants, and comprises patient delays, for example, due to a lack of knowledge about the health system in the host country, and health worker delays, often compounded by communication barriers. Improvements in family planning and antenatal services are needed, and audits and confidential enquiries should be extended to include maternal morbidity and ethnic background. This requires scientific and political efforts.

Suboptimal care and maternal mortality among foreign-born women in Sweden: maternal death audit with application of the 'migration three delays' model

BACKGROUND

Several European countries report differences in risk of maternal mortality between immigrants from low- and middle-income countries and host country women. The present study identified suboptimal factors related to care-seeking, accessibility, and quality of care for maternal deaths that occurred in Sweden from 1988-2010.

METHODS

A subset of maternal death records (n = 75) among foreign-born women from low- and middle-income countries and Swedish-born women were audited using structured implicit review. One case of foreign-born maternal death was matched with two native born Swedish cases of maternal death. An assessment protocol was developed that applied both the 'migration three delays' framework and a modified version of the Confidential Enquiry from the United Kingdom. The main outcomes were major and minor suboptimal factors associated with maternal death in this high-income, low-maternal mortality context.

RESULTS

Major and minor suboptimal factors were associated with a majority of maternal deaths and significantly more often to foreign-born women (p = 0.01). The main delays to care-seeking were non-compliance among foreign-born women and communication barriers, such as incongruent language and suboptimal interpreter system or usage. Inadequate care occurred more often among the foreign-born (p = 0.04), whereas delays in consultation/referral and miscommunication between health care providers where equally common between the two groups.

CONCLUSIONS

Suboptimal care factors, major and minor, were present in more than 2/3 of maternal deaths in this high-income setting. Those related to migration were associated to miscommunication, lack of professional interpreters, and limited knowledge about rare diseases and pregnancy complications. Increased insight into a migration perspective is advocated for maternity clinicians who provide care to foreign-born women.

Factors affecting the use of prenatal care by non-western women in industrialized western countries: a systematic review

Background

Despite the potential of prenatal care for addressing many pregnancy complications and concurrent health problems, non-western women in industrialized western countries more often make inadequate use of prenatal care than women from the majority population do. This study aimed to give a systematic review of factors affecting non-western women’s use of prenatal care (both medical care and prenatal classes) in industrialized western countries.

Methods

Eleven databases (PubMed, Embase, PsycINFO, Cochrane, Sociological Abstracts, Web of Science, Women’s Studies International, MIDIRS, CINAHL, Scopus and the NIVEL catalogue) were searched for relevant peer-reviewed articles from between 1995 and July 2012. Qualitative as well as quantitative studies were included. Quality was assessed using the Mixed Methods Appraisal Tool. Factors identified were classified as impeding or facilitating, and categorized according to a conceptual framework, an elaborated version of Andersen’s healthcare utilization model.

Results

Sixteen articles provided relevant factors that were all categorized. A number of factors (migration, culture, position in host country, social network, expertise of the care provider and personal treatment and communication) were found to include both facilitating and impeding factors for non-western women’s utilization of prenatal care. The category demographic, genetic and pregnancy characteristics and the category accessibility of care only included impeding factors.

Lack of knowledge of the western healthcare system and poor language proficiency were the most frequently reported impeding factors. Provision of information and care in women’s native languages was the most frequently reported facilitating factor.

Conclusion

The factors found in this review provide specific indications for identifying non-western women who are at risk of not using prenatal care adequately and for developing interventions and appropriate policy aimed at improving their prenatal care utilization.

Maternal mortality in Sweden 1988-2007: more deaths than officially reported

OBJECTIVE

To obtain more accurate calculations of maternal and pregnancy-related mortality ratios in Sweden from 1988 to 2007 by using information from national registers and death certificates.

DESIGN

A national register-based study, supplemented by a review of death certificates.

SETTING

Sweden, 1988-2007.

POPULATION

The deaths of 27 957 women of reproductive age (15-49 years).

METHODS

The Swedish Cause of Death Register, Medical Birth Register, and National Patient Register were linked. All women with a diagnosis related to pregnancy in at least one of these registers within 1 year prior to death were identified. Death certificates were reviewed to ascertain maternal deaths. Maternal mortality ratio (the number of maternal deaths/100 000 live births, excluding and including suicides), and pregnancy-related mortality ratio (number of deaths within 42 days after termination of pregnancy, irrespective of cause of death/100 000 live births) were calculated.

MAIN OUTCOME MEASURES

Direct and indirect maternal deaths and pregnancy-related deaths.

RESULTS

The maternal mortality ratio in Sweden, based on the current method of identifying maternal deaths, was 3.6. After linking registers and reviewing death certificates, we identified 64% more maternal deaths, resulting in a ratio of 6.0 (or 6.5 if suicides are included). The pregnancy-related mortality ratio was 7.3. A total of 478 women died within a year after being recorded with a diagnosis related to pregnancy.

CONCLUSIONS

By including the 123 cases of maternal death identified in this study, the mean maternal mortality ratio from 1988 to 2007 was 64% higher than reported to the World Health Organization.

Excess mortality in women of reproductive age from low-income countries: a Swedish national register study

Background: Cause-of-death statistics is widely used to monitor the health of a population. African immigrants have, in several European studies, shown to be at an increased risk of maternal death, but few studies have investigated cause-specific mortality rates in female immigrants. Methods: In this national study, based on the Swedish Cause of Death Register, we studied 27 957 women of reproductive age (aged 15–49 years) who died between 1988 and 2007. Age-standardized mortality rates per 100 000 person years and relative risks for death and underlying causes of death, grouped according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, were calculated and compared between women born in Sweden and in low-, middle- and high-income countries. Results: The total age-standardized mortality rate per 100 000 person years was significantly higher for women born in low-income (84.4) and high-income countries (83.7), but lower for women born in middle-income countries (57.5), as compared with Swedish-born women (68.1). The relative risk of dying from infectious disease was 15.0 (95% confidence interval 10.8–20.7) and diseases related to pregnancy was 6.6 (95% confidence interval 2.6–16.5) for women born in low-income countries, as compared to Swedish-born women. Conclusions: Women born in low-income countries are at the highest risk of dying during reproductive age in Sweden, with the largest discrepancy in mortality rates seen for infectious diseases and diseases related to pregnancy, a cause of death pattern similar to the one in their countries of birth. The World Bank classification of economies may be a useful tool in migration research.

Shared language is essential: communication in a multiethnic obstetric care setting

This study focuses on communication and conceptions of obstetric care to address the postulates that immigrant women experience sensitive care through the use of an ethnically congruent interpreter and that such women prefer to meet health providers of the same ethnic and gender profile when in a multiethnic obstetrics care setting. During 2005-2006, we conducted in-depth interviews in Greater London with immigrant women of Somali and Ghanaian descent and with White British women, as well as with obstetric care providers representing a variety of ethnic profiles. Questions focused on communication and conceptions of maternity care, and they were analyzed using qualitative techniques inspired by naturalistic inquiry. Women and providers across all informant groups encountered difficulties in health communication. The women found professionalism and competence far more important than meeting providers from one's own ethnic group, while language congruence was considered a comfort. Despite length of time in the study setting, Somali women experienced miscommunication as a result of language barriers more than did other informants. An importance of the interpreter's role in health communication was acknowledged by all groups; however, interpreter use was limited by issues of quality, trust, and accessibility. The interpreter service seems to operate in a suboptimal way and has potential for improvement.

What about the mothers? An analysis of maternal mortality and morbidity in perinatal health surveillance systems in Europe

OBJECTIVE

To assess capacity to develop routine monitoring of maternal health in the European Union using indicators of maternal mortality and severe morbidity.

DESIGN

Analysis of aggregate data from routine statistical systems compiled by the EURO-PERISTAT project and comparison with data from national enquiries.

SETTING

Twenty-five countries in the European Union and Norway.

POPULATION

Women giving birth in participating countries in 2003 and 2004.

METHODS

Application of a common collection of data by selecting specific International Classification of Disease codes from the 'Pregnancy, childbirth and the puerperium' chapter. External validity was assessed by reviewing the results of national confidential enquiries and linkage studies.

MAIN OUTCOME MEASURES

Maternal mortality ratio, with distribution of specific obstetric causes, and severe acute maternal morbidity, which included: eclampsia, surgery and blood transfusion for obstetric haemorrhage, and intensive-care unit admission.

RESULTS

In 22 countries that provided data, the maternal mortality ratio was 6.3 per 100,000 live births overall and ranged from 0 to 29.6. Under-ascertainment was evident from comparisons with studies that use enhanced identification of deaths. Furthermore, routine cause of death registration systems in countries with specific systems for audit reported higher maternal mortality ratio than those in countries without audits. For severe acute maternal morbidity, 16 countries provided data about at least one category of morbidity, and only three provided data for all categories. Reported values ranged widely (from 0.2 to 1.6 women with eclampsia per 1000 women giving birth and from 0.2 to 1.0 hysterectomies per 1000 women).

CONCLUSIONS

Currently available data on maternal mortality and morbidity are insufficient for monitoring trends over time in Europe and for comparison between countries. Confidential enquiries into maternal deaths are recommended.

The etiology of maternal mortality in developed countries: a systematic review of literature

PURPOSE

To review the literature about MD in developed countries.

METHODS

A search in PubMed, EMBASE, Medline and reference lists was performed. Key words: maternal death/mortality, pregnancy death and obstetric/maternity care. Articles were selected if they reported the cause of death per livebirths, were performed in developed countries and unselected population, classified MD by the World Health Organization. Maternal age, cause of MD, time of MD (antepartum, intrapartum, postpartum) and delivery mode were abstracted. MD was expressed as maternal mortality ratio (MMR). PRISMA guidelines were followed.

RESULTS

Twelve articles provided data from 1980 to 2007. The MD rate was 9,750 in 75,560,683 livebirths (MMR: 12.90). MD was direct in 6,791 women (MMR: 8.98), being postpartum hemorrhage the leading cause, and indirect in 2,786 women (MMR: 3.68), with cardiovascular disease as the main cause. The remaining 173 deaths (MMR: 0.22) were unexplained. Maternal age >45 years, vaginal delivery, postpartum period increased the risk of MD. MD reduced over time in all countries except in the Netherlands and USA.

CONCLUSIONS

Conditions leading to hemorrhage warrant strict management. The risk of an apparently healthy woman to die during motherhood is 0.22 out of 100,000 livebirths.

Understanding regional differences in maternal mortality: a national case-control study in France

OBJECTIVES

To assess the risk of postpartum maternal death associated with region, and to examine whether the quality of care received by the women who died differed by region.

DESIGN

A national case-control study.

SETTING

France.

POPULATION

Selected from recent nationwide surveys, 328 postpartum maternal deaths from 2001 through 2006 as cases; and a representative sample (n = 14 878) of women who gave birth in 2003 as controls.

METHODS

Crude and adjusted odds ratios (aOR) of maternal death associated with region were calculated with logistic regression, and the quality of care for women who died was compared according to region with chi-square tests or Fisher's exact tests.

MAIN OUTCOME MEASURES

Risk of postpartum maternal death associated with region, and quality of care.

RESULTS

After adjustment for maternal age and nationality, the risk of maternal death was higher in the Ile-de-France region (aOR 1.6, 95% CI 1.2-2.0) and the overseas districts (aOR 3.5, 95% CI 2.4-5.0) than in the group for the rest of continental France. In both regions, the excess risk of death from haemorrhage, amniotic fluid embolism and hypertensive disorders was significant. In continental France, after further controlling for women's obstetric characteristics, the risk of maternal death in Ile-de-France remained higher (aOR 1.8. 95% CI 1.3-2.6). The women in the cases groups received suboptimal care more frequently in Ile-de-France than in the other continental regions (64% versus 43%, P = 0.01).

CONCLUSIONS

These results suggest that quality of care and organisation of health services may play a role in the differential risk of maternal mortality between regions in France. Research on severe maternal morbidity and its determinants is needed to clarify the mechanisms involved.

Maternal mortality in a Nigerian teaching hospital - a continuing tragedy

The aim of this review is to determine the maternal mortality ratio (MMR) in a Nigerian tertiary health institution (University of Ilorin Teaching Hospital, Ilorin, Nigeria). The review was done through a retrospective analysis of maternal mortality records. The MMR for the 6-year period (1997-2002) was 825 per 100,000 live births. The common causes of maternal mortality included severe pre-eclampsia/eclampsia, 30 (27.8%); haemorrhage, 22 (20.4%) and complications of unsafe abortion 16 (14.8%). Grandmultiparous and patients aged 40 years and above were at the highest risk. This hospital-based MMR is very high and when compared with previous reports showed a 150% increase. Most of the maternal deaths are, however, preventable. Increased efforts at educating women, improvement of the socioeconomic conditions of the populace and strong political commitment in making emergency obstetric care available in rural and district hospitals are some of the measures that need to be adopted to reduce this avoidable tragedy.

Maternal mortality: who, when, where, and why

The risk of a woman dying as a result of pregnancy or childbirth during her lifetime is about one in six in the poorest parts of the world compared with about one in 30 000 in Northern Europe. Such a discrepancy poses a huge challenge to meeting the fifth Millennium Development Goal to reduce maternal mortality by 75% between 1990 and 2015. Some developed and transitional countries have managed to reduce their maternal mortality during the past 25 years. Few of these, however, began with the very high rates that are now estimated for the poorest countries-in which further progress is jeopardised by weak health systems, continuing high fertility, and poor availability of data. Maternal deaths are clustered around labour, delivery, and the immediate postpartum period, with obstetric haemorrhage being the main medical cause of death. Local variation can be important, with unsafe abortion carrying huge risk in some populations, and HIV/AIDS becoming a leading cause of death where HIV-related mortaliy rates are high. Inequalities in the risk of maternal death exist everywhere. Targeting of interventions to the most vulnerable--rural populations and poor people--is essential if substantial progress is to be achieved by 2015.

Pregnancy outcomes in foreign-born and US-born women

OBJECTIVES

To compare pregnancy outcomes between foreign-born women and women born in the United States (US-born).

METHODS

A retrospective cohort study (1991-2001) of all deliveries at Grady Memorial Hospital in Atlanta, Georgia.

RESULTS

Among 49,904 deliveries, 27% were to foreign-born mothers representing 164 countries grouped into eight geographic regions. Compared with US-born women, foreign-born women had a higher mean birthweight (3315 vs. 3083 g), and a lower risk of preterm delivery (RR 0.46, 95% CI 0.43-0.49), perinatal mortality (RR 0.40, 95% CI 0.36-0.45), hypertension (RR 0.31, 95% CI 0.23-0.41), and HIV infection (RR 0.13, 95% CI 0.10-0.18). However, foreign-born women had an increased risk of diabetes (RR 1.63, 95% CI 1.48-1.79), perineal laceration (RR 1.71; 95% CI 1.66-1.76), and postpartum hemorrhage (RR 1.10; 95% CI 1.05-1.15).

CONCLUSIONS

Foreign-born women have better health behaviors, pregnancy outcomes, and a lower risk of infectious diseases than US-born women, but they have a higher risk of certain medical conditions and obstetric complications.

Time travel with Oliver Twist--towards an explanation foa a paradoxically low mortality among recent immigrants

First-generation immigrant populations in industrialized countries frequently have a lower mortality than the host population, a finding that is unexpected and often dismissed as the result of bias. We propose an alternative explanation for a real, albeit temporal, mortality advantage. We base our argument on two premises: First, that there are differences in the progression of the health transition between the immigrants' countries of origin and industrialized host countries; and, second, that there are differences in the speed at which changes in mortality from various causes occur after migration. Mortality from treatable communicable and maternal conditions, still high in many countries of origin, quickly declines to levels close to those of the host country. Mortality from ischaemic heart disease, the most common cause of death in the host countries, takes years or decades to rise to comparable heights. This is because of the time lag between increases in risk factor levels and an increased risk of coronary death. Hence, first-generation immigrants may initially experience a lower mortality than the host population, a point that has so far been under-appreciated in discussions of immigrant mortality. After adopting a western lifestyle immigrants face an increasing risk of ischaemic heart disease. The increase occurs on top of a persisting risk from conditions associated with childhood deprivation, e.g. stomach cancer and stroke--the unfinished agenda of the health transition that immigrants experience.

Maternal mortality in Greece (1980-1996)

OBJECTIVE

To use data from the National Statistical Service of Greece to examine trends in maternal mortality and risk factors for maternal deaths.

STUDY DESIGN

Maternal mortality in Greece has been studied from years 1980 to 1996 in total, by cause of death, by residency (urban/rural) and by maternal age. The maternal mortality ratio (MMR) has been defined as the number of deaths per 100,000 live births.

RESULTS

From years 1980 to 1996, there have been 136 maternal deaths (MMR: 7). The number of deaths has significantly decreased during this period and six major causes of death have been identified, resulting in 80% of maternal deaths. A simulation of maternal mortality between urban and rural areas has been achieved during the last decade. Also, maternal mortality rises dramatically with age.

CONCLUSIONS

Although overall rates of maternal mortality in Greece have been significantly decreased over the last years, an improved recording of maternal deaths is necessary for identifying preventable factors and developing effective interventions.

Maternal mortality in rural India: a hospital based, 10 year retrospective analysis

OBJECTIVES

To estimate the maternal mortality ratio (MMR) in Ludhiana, a city of Northern India in order to determine the causes associated with MMR and to suggest ways to reduce it.

METHODS

Retrospective analysis of the mortality records of obstetrics cases in Christian Medical College, Ludhiana, India.

RESULTS

The mean MMR for the 10 year period was 785 per 100,000 live births. Of the total 116 reported maternal deaths, 44 (41.9%) were due to induced septic abortion. The reasons were unwanted pregnancy in 22 (50%) and 11 (25%) were female feticide.

CONCLUSIONS

In our hospital based analysis, MMR was very high. Most maternal deaths are preventable by intervention at the appropriate time and it is important for health professionals, policy makers and politicians to implement the introduction of programs for reducing maternal mortality. Special emphasis should be placed on antenatal care, the establishment of a registration system and measures to abolish illegal abortion.

Risk factors for pre-eclampsia in a large cohort of Latin American and Caribbean women

OBJECTIVE

To study risk factors for pre-eclampsia in a large cohort of Latin American and Caribbean women.

DESIGN

Retrospective cross-sectional study from the Perinatal Information System, the database of the Latin American Center for Perinatology and Human Development, Montevideo, Uruguay.

SETTING

Latin America and the Caribbean, 1985-1997. Population 878,680 pregnancies at 700 hospitals; of these 42,530 were complicated by pre-eclampsia and 1,872 by eclampsia.

MAIN OUTCOME MEASURES

Crude and adjusted relative risks (RR) of risk factors for pre-eclampsia. Adjusted relative risks were obtained after adjustment for potential confounding factors through multiple logistic regression models based on the method of generalised estimating equations.

RESULTS

The following risk factors were significantly associated with increased risk of pre-eclampsia: nulliparity (RR 2 x 38; 95% CI 2 x 28-2 x 49); multiple pregnancy (RR 2 x 10; 95% CI 1 x 90-2 x 32); history of chronic hypertension (RR 1 x 99; 95% CI 1 x 78-2 x 22); gestational diabetes mellitus (RR 1 x 93; 95% CI 1 x 66-2 x 25); maternal age > or = 35 years (RR 1 x 67; 95% CI 1 x 58-1 x 77); fetal malformation (RR 1 x 26; 95% CI 1 x 16-1 x 37); and mother not living with infant's father (RR 1 x 21; 95% CI 1 x 15-1 x 26). Pre-eclampsia risk increased according to pre-pregnancy body mass index (BMI). In comparison with women with a normal pre-pregnancy BMI (19 x 8 to 26 x 0), the RR estimates were 1 x 57 (95% CI 1 x 49-1 x 64) and 2 x 81 95% CI 2 x 69-2 x 94), respectively, for overweight women (pre-pregnancy BMI = 26 x 1 to 29 x 0) and obese women (pre-pregnancy BMI > 29 x 0). Cigarette smoking during pregnancy and a pre-pregnancy BMI < 19 x 8 were significant protective factors against the development of pre-eclampsia. The pattern of risk factors among nulliparous and multiparous women was quite similar.

CONCLUSIONS

Risk factors for pre-eclampsia observed among Latin American and Caribbean women are similar to those found among North American and European women.

Precarity and pregnancy in Paris

OBJECTIVE

Our purpose was to assess to what extent the absence of health insurance (Social Security) contributes to poor pregnancy outcome.

STUDY DESIGN

A prospective, population-based study compared the perinatal outcome of women without Social Security (n=243) to a contemporaneous control group (n=243) and to a group of women (n=32) with Social Security but presenting another risk factor for precarity (a judicial child-mother separation sentence).

RESULTS

Prenatal consultations were less frequent and initiated later for women without Social Security than for controls. There was no difference between these two groups concerning maternal morbidity (premature labour, hypertension, gestational diabetes, post-partum complications) or maternal mortality, no difference for the mode of delivery and the rate of low birth-weight, foetal death, and neonatal morbidity (hypoglycaemia, hypocalcemia, anaemia, jaundice, infection and transfer to intensive care unit). The rate of prematurity was not significantly higher in the group without Social Security compared to the control group (11.1% versus 6.2%, P=0.08). However, in the group with Social Security and a court sentence of child mother separation, the rate of fetal growth retardation, prematurity, home delivery, caesarean section, neonatal drug deprivation syndrome and transfer to an intensive care unit was significantly higher compared to the two other groups (P<0.01).

CONCLUSION

In our study, absence of Social Security during pregnancy is not a major determinant of poor pregnancy outcome, whereas other factors of precarity seem to be more influential.

Confidential enquiry into maternal deaths in The Netherlands 1983-1992

OBJECTIVE

To determine the causes of maternal death in The Netherlands.

STUDY DESIGN

Nationwide Confidential Enquiry into the Causes of Maternal Deaths during the period 1983-1992.

RESULTS

Of 192 direct and indirect maternal deaths, 154 (80%) were available for the Enquiry. The most frequent direct causes were (pre-)eclampsia, thrombo-embolism, obstetrical haemorrhage and sepsis. Cerebro- and cardiovascular disorders were the most frequent indirect causes of death. Age above 35 years and parity 3 or more are related to higher maternal mortality. Women from non-caucasian origin are more prone to death in comparison to caucasian women. Autopsy was performed in 88 cases (57%). Of the 24 women where labour started at home, the place of birth played a significant role in delay in four.

CONCLUSIONS

More efforts should be made to have a higher percentage than 80% available for the Confidential Enquiry as in the UK where only 1-4% of deaths are not available for similar purposes. Also, the autopsy rate of 57% is much lower than in the UK (82%). Special strategies should be developed to improve maternal health of populations at higher risk such as women of high age and parity and immigrant populations.

Barbados Low Dose Aspirin Study in Pregnancy (BLASP): a randomised trial for the prevention of pre-eclampsia and its complications

OBJECTIVE

To determine whether prophylactic, low dose controlled-release aspirin improves outcome for pregnant women and their babies in Barbados.

DESIGN

Randomised placebo-controlled trial.

SETTING

The Queen Elizabeth Hospital, Barbados.

POPULATION

All women attending antenatal clinics between 12 and 32 weeks of gestation were eligible, if without specific contraindications to aspirin and unlikely to deliver immediately.

METHODS

Randomisation was computer-generated in the antenatal clinic; 1822 women were allocated to receive 75 mg controlled-release aspirin and 1825 matching placebo.

MAIN OUTCOME MEASURES

Proteinuric pre-eclampsia, other pregnancy-induced hypertension, pregnancy duration, birthweight, stillbirths and neonatal deaths, major neonatal events.

RESULTS

All but three women from each group were followed up successfully. Forty-four percent were primigravid, and 8% had previous obstetric complications. There were no significant differences between the allocated treatment groups in the incidence of proteinuric pre-eclampsia (40 [2.2%] of those allocated aspirin, compared with 46 [2.5%] allocated placebo), of preterm delivery (255 [14.0%] vs 270 [14.8%]), of birthweight < 1500 g (32 [1.7%] vs 33 [1.8%]) or of stillbirth and neonatal death (44 [2.4%] vs 38 [2.1%]). Aspirin was not associated with excess risk of maternal or fetal bleeding.

CONCLUSIONS

The results of this study in Barbados do not support the routine use of low dose aspirin for prevention of pre-eclampsia or its complications, confirming results of previous large trials in other settings.
