Estimation of maternal and neonatal mortality at the subnational level in Liberia

Objective

To establish representative local-area baseline estimates of maternal and neonatal mortality using a novel adjusted sisterhood method.

Methods

The status of maternal and neonatal health in Bomi County, Liberia, was investigated in June 2013 using a population-based survey (n = 1985). The standard direct sisterhood method was modified to account for place and time of maternal death to enable calculation of subnational estimates.

Results

The modified method of measuring maternal mortality successfully enabled the calculation of area-specific estimates. Of 71 reported deaths of sisters, 18 (25.4%) were due to pregnancy-related causes and had occurred in the past 3 years in Bomi County. The estimated maternal mortality ratio was 890 maternal deaths for every 100 000 live births (95% CI, 497–1301]. The neonatal mortality rate was estimated to be 47 deaths for every 1000 live births (95% CI, 42–52). In total, 322 (16.9%) of 1900 women with accurate age data reported having had a stillbirth.

Conclusion

The modified direct sisterhood method may be useful to other countries seeking a more regionally nuanced understanding of areas in which neonatal and maternal mortality levels still need to be reduced to meet Millennium Development Goals.     

Maternal mortality in Denmark, 1985–1994

Objectives

In Denmark, maternal mortality has been reported over the last century, both locally through hospital reports and in national registries. The purpose of this study was to analyze data from national medical registries of pregnancy-related deaths in Denmark 1985–1994 and to classify them according to the UK Confidential Enquiry into Maternal Deaths (CEMD).

Study design

All deaths of women with a registered pregnancy within 12 months prior to the death were identified by comparing the Danish medical registries, death certificates, and relevant codes according to International Classification of Diseases (ICD-10). All cases were classified using the UK CEMD classification. Cases of maternal death were further evaluated by an audit group.

Results

311 cases were classified. 92 deaths (29.6%) occurred ≤42 days after termination of pregnancy. Of these, 30 were classified as direct obstetric deaths, 30 as indirect obstetric deaths, and 32 as fortuitous deaths. Among the late pregnancy-related deaths (>42 days), 1 woman died from a direct obstetric cause, 46 from indirect causes, and 172 from fortuitous causes. Hypertensive disorders of pregnancy were the major cause of direct maternal deaths. The rate of maternal deaths constituted 9.8/100,000 maternities (i.e. the number of women delivering registrable live births at any gestation or stillbirths at 24 weeks of gestation or later).

Conclusion

This is the first systematic report on deaths in Denmark based on data from national registries. The maternal mortality rate in Denmark is comparable to the rates in other developed countries. Fortunately, statistics are low, but each case represents potential learning.Obstetric care has changed and classification methods differ between countries. Prospective registration and registry linkage seem to be a way to ensure completion. This retrospective study has provided the background for a prospective study on registration and evaluation of maternal mortality in Denmark.     

National maternal mortality ratio for Jordan, 2007-2008

Objective

To estimate the number of maternal deaths per 100 000 live births during 2007-2008 among Jordanian women; to identify the causes of maternal mortality; and to compare the results with those of the last report for 1995-1996.

Methods

Reproductive-age mortality study of maternal deaths among women aged 15-49 years in Jordan in 2007-2008.

Results

Among 1406 identified deaths of reproductive-aged women, 76 maternal deaths were identified out of 397 588 live births, for a maternal mortality ratio of 19.1 deaths per 100 000 live births. Forty-three (56.6%) deaths were attributable to hemorrhage, thrombosis and thromboembolism, and sepsis. Avoidable factors were present in 53.9% of women, 52.6% had substandard care, and 31.5% had 3 or fewer antenatal visits. Of those with available information on family planning, only 29.4% had ever used any form of contraception.

Conclusions

Maternal deaths in Jordan are declining. The maternal mortality ratio of 19.1 deaths per 100 000 live births reported for 2007-2008 showed a remarkable reduction of 53.9% achieved in the 12 years since the 1995-1996 report (a 4.5% annual reduction), which is approaching the 75% reduction recommended by Millennium Development Goal 5.     

Severe maternal morbidity

Objectives

Severe maternal morbidity remains a public health issue in developing countries. We report in this retrospective study, patients' characteristics and frequency of pathologies responsible of severe maternal morbidity.

Materials and methods

Between January 1999 and December 2003, 119 cases of severe maternal pathologies of pregnancy and delivery occurred among 19,736 live births.

Results

Severe maternal morbidity was 602.95 per 100,000 live births and obstetrical haemorrhages were the most frequent cause (39%) followed by hypertensive disease (25%). Maternal mortality rate was 30.4 per 100,000 live births, and hypertensive disease represents the first cause of mortality in our study, contrary to all Tunisian data where haemorrhage remains the first one.

Conclusion

Improvement of prognostic of high risk pregnancies has allowed diminution of maternal mortality. Instead of this diminution, efforts must be done in the management of severe obstetrical pathologies responsible of high maternal morbidity notably complications of hypertensive disease.     

Assessment of maternal near-miss and quality of care in a hospital-based study in Accra,Ghana

Objective

To assess the baseline incidence of maternal near-miss, process indicators related to facility access, and quality of care at a tertiary care facility in urban Ghana.

Methods

A prospective observational study of all women delivering at the facility, including those with pregnancy-related complications, was conducted between October 2010 and March 2011. Quality of maternal health care was assessed via a newly developed WHO instrument based on near-miss criteria and criterion-based clinical audit methodology.

Results

Among 3438 women, 516 had potentially life-threatening conditions and 131 had severe maternal outcomes (94 near-miss cases and 37 maternal deaths). More than half (64.4%) of the women had been referred to the facility. The incidence of maternal near-miss was 28.6 cases per 1000 live births. Anemia contributed to most cases with a severe maternal outcome. More than half of all women with severe maternal outcomes developed organ dysfunction or died within the first 12 hours of hospital admission. Although preventive measures were prevalent, treatment-related indicators showed mixed results.

Conclusion

The WHO near-miss approach was found to represent a feasible strategy in low-resource countries. Improving referral systems, effective use of critical care, and evidence-based interventions can potentially reduce severe maternal outcomes.     

Insights into maternal mortality in Madang Province,Papua New Guinea

Objective

To assess the frequency, causes, and reporting of maternal deaths at a provincial referral hospital in coastal Papua New Guinea (PNG), and to describe delays in care.

Methods

In a structured retrospective review of maternal deaths at Modilon General Hospital, Madang, PNG, registers and case notes for the period January 2008 to July 2012 were analyzed to determine causes, characteristics, and management of maternal death cases. Public databases were assessed for underreporting.

Results

During the review period, there were 64 maternal deaths (institutional maternal mortality ratio, 588 deaths per 100 000 live births). Fifty-two cases were analyzed in detail: 71.2% (n = 37) were direct maternal deaths, and hemorrhage (n = 24, 46.2%) and infection (n = 16, 30.8%) were the leading causes of mortality overall. Women frequently did not attend prenatal clinics (n = 34, 65.4%), resided in rural areas (n = 45, 86.5%), and experienced delays in care (n = 45, 86.5%). Maternal deaths were underreported in public databases.

Conclusion

The burden of maternal mortality was found to be high at a provincial hospital in PNG. Most women died of direct causes and experienced delays in care. Strategies to complement current hospital and national policy to reduce maternal mortality and to improve reporting of deaths are needed.     

Pilot community-mobilization program reduces maternal and perinatal mortality and prevents obstetric fistula in Niger

Objective

To assess the impact of a pilot community-mobilization program on maternal and perinatal mortality and obstetric fistula in Niger.

Methods

In the program, village volunteers identify and evacuate women with protracted labor, provide education, and collect data on pregnancies, births, and deaths. These data were used to calculate the reduction in maternal mortality, perinatal mortality, and obstetric fistula in the program area from July 2008 to June 2011.

Results

The birth-related maternal mortality fell by 73.0% between years 1 and 3 (P < 0.001), from 630 (95% confidence interval [CI] 448–861) to 170 (95% CI 85–305) deaths per 100 000 births. Early perinatal mortality fell by 61.5% (P < 0.001), from 35 (95% CI 31–40) to 13 (95% CI 10–16) deaths per 1000 births. No deaths due to obstructed labor were reported after the lead-in period (February to June 2008). Seven cases of community-acquired fistula were reported between February 2008 and July 2009; from August 2009 to June 2011 (23 months; 12 254 births), no cases were recorded.

Conclusion

Community mobilization helped to prevent obstetric fistula and birth-related deaths of women and infants in a large, remote, resource-poor area.     

Acknowledging HIV and malaria as major causes of maternal mortality in Mozambique

Objective

To review national data on HIV and malaria as causes of maternal death and to determine the importance of looking at maternal mortality at a subnational level in Mozambique.

Methods

Three national data surveys were used to document HIV and malaria as causes of maternal mortality and to assess HIV and malaria prevention services for pregnant women. Data were collected between 2007 and 2011, and included population-level verbal autopsy data and household survey data.

Results

Verbal autopsy data indicated that 18.2% of maternal deaths were due to HIV and 23.1% were due to malaria. Only 19.6% of recently pregnant women received at least two doses of sulfadoxine-pyrimethamine for intermittent preventive treatment, and only 42.3% of pregnant women were sleeping under an insecticide-treated net. Only 37.5% of recently pregnant women had been counseled, tested, and received an HIV test result. Coverage of prevention services varied substantially by province.

Conclusion

Triangulation of information on cause of death and coverage of interventions can enable appropriate targeting of maternal health interventions. Such information could also help countries in Sub-Saharan Africa to recognize and take action against malaria and HIV in an effort to decrease maternal mortality.     

Maternal mortality in Greece, 1996-2006

Objective

To present retrospective data for maternal deaths in Greece from 1996 to 2006.

Methods

Demographic information and information on the causes of death was provided by the Hellenic Statistical Authority. Maternal deaths were assessed by cause of death, maternal age, and place of residence. The maternal mortality ratio (MMR) was estimated and expressed as the number of deaths per 100 000 live births.

Results

From 1996 to 2006, 29 deaths were attributed to pregnancy and childbirth, yielding a total MMR of 2.63. The leading cause of direct deaths was hemorrhage and that of indirect deaths was cardiac disease. There was a borderline significant decline in the MMR during the study period. The MMR was significantly higher at the extremes of the reproductive age range.

Conclusion

Maternal mortality in Greece is low; however, no formal data have been published since 1996. Knowledge of the causes of maternal death can lead to the prevention of maternal deaths and safer motherhood.     

Maternal Mortality and Its Causes in a Tertiary Center

Objectives

To study the maternal mortality and the complications leading to maternal death.

Methods

A retrospective study of hospital records and death summaries of all maternal deaths over the period from January 2000 to August 2009 was carried out.

Results

There were a total of 80 maternal deaths out of 88,443 live births giving maternal mortality rate (MMR) of 90.45 per 100,000 live births. Unbooked and late referral accounted for 77.5 % of maternal deaths. The majority of the deaths was in 30–40-year age group and around term. Hemorrhage was the commonest cause of death (52.5 %), followed by sepsis (13.75 %) and pregnancy-induced hypertension including eclampsia (10 %).

Conclusions

Hemorrhage, sepsis, and pregnancy-induced hypertension including eclampsia were found to be the direct major causes of death. Anemia and cardiac disease were other indirect causes of deaths.     

A review of cultural influence on maternal mortality in the developing world

Objective

identify research examining the effect of culture on maternal mortality rates.

Design

literature review of CINAHL, Cochrane, PsychInfo, OVID Medline and Web of Science databases.

Setting

developing countries with typically higher rates of maternal mortality.

Participants

women, birth attendants, family members, nurse midwives, health-care workers, and community members.

Measurements and findings

reviews, qualitative and mixed-methods research have identified components of culture that have a direct impact on maternal mortality. Examples of culture are given in the text and categorised according to the way in which they impact maternal mortality.

Key conclusions

cultural customs, practices, beliefs and values profoundly influence women's behaviours during the perinatal period and in some cases increase the likelihood of maternal death in childbirth. The four ways in which culture may increase MMR are as follows: directly harmful acts, inaction, use of care and social status.

Implications for practice

understanding the specifics of how the culture surrounding childbirth contributes to maternal mortality can assist nurses, midwives and other health-care workers in providing culturally competent care and designing effective programs to help decrease MMR, especially in the developing world. Interventions designed without accounting for these cultural factors are likely to be less effective in reducing maternal mortality.     

Place of birth or place of death: An evaluation of 1139 maternal deaths in Nigeria

Objective

to describe the incidence of maternal death by age, marital status, timing and place of death in Ibadan North and Ido Local Government Areas of Oyo State, Nigeria.

Design

a retrospective study using multistage sampling with stratification and clustering to select local government areas, political wards and households. We included one eligible subject by household in the sample. Data on maternal mortality were collected using the principles of the indirect sisterhood method.

Setting

Ibadan city of Oyo state, Nigeria. We included eight randomly selected political wards from Ibadan North LGA (urban) and Ido LGA (rural).

Participants

3028 participants were interviewed using the four questions of the indirect sisterhood method: How many sisters have you ever had who are ever married (or who survived until age 15)? How many are dead? How many are alive? How many died while they were pregnant, during childbirth, or within six weeks after childbirth (that is, died of maternal causes)? We also included other questions such as place and timing of death, age of women at death and number of pregnancies.

Findings

1139 deaths were reported to be related to pregnancy, childbirth or the puerperium. Almost half were aged between aged 25–34 years. More deaths occurred to women who were pregnant for the first time (33.4%, n=380) than for any other number of pregnancies, with 49.9% (n=521) dying within 24 hours after childbirth or abortion and 30.9% (n=322) dying after 24 hours but within 72 hours after childbirth or abortion. Only 71.5% (n=809) were reported to have been admitted to health-care facilities before their death, the percentage being higher in the urban LGA (72.4%, n=720) than the rural LGA (65.4%, n=89). The percentage being admitted varied from one political ward to another (from 42.9% to 80.4%), the difference being statistically significant (χ²=17.55, df=7, p=0.014). The majority of the deaths occurred after childbirth (63.5%, n=723). Most deaths were said to have occurred in the hospital (38.6%) or private clinic (28.2%), with 16.0% dying at home and 6.5% on the way to hospital.

Key conclusions

maternal mortality in Nigeria is still unacceptably high.

Implications for practice

ensure adequate training, recruitment and deployment of midwives and others with midwifery skills. Ensure midwives and other skilled birth attendants are backed up with functioning and well equipped health-care facilities. Provide health education and information to the public with regard to reproductive health and ensure the development and dissemination of a policy regarding attendance at birth by only health workers who have midwifery skills.     

Preterm birth and neonatal mortality in China in 2011

Objective

To determine the incidence of preterm birth, its regional distribution, and associated neonatal mortality in mainland China.

Methods

In a multicenter, hospital-based investigation of preterm birth, 2011 data were obtained from the seven administrative regions of mainland China. Between one and three subcenters were randomly selected for each administrative region, followed by secondary and tertiary hospitals within the chosen subcenters. Data were obtained from women’s medical records, and obstetric and perinatal events were summarized.

Results

Data for 107 905 deliveries were analyzed, which included 7769 (7.1%) preterm births (occurring between 28 and 37 weeks of pregnancy). The incidence varied among regions. Late preterm birth (between 34 and 37 weeks) accounted for 5495 (70.7%) of preterm births. The neonatal mortality rate was 33 deaths per 1000 live preterm births. Of the 254 neonatal deaths, 147 (57.9%) occurred after very preterm birth (between 28 and 32 weeks). Overall, 4519 (58.2%) preterm births occurred by cesarean.

Conclusion

The distribution of preterm birth across China is unbalanced, and neonatal mortality associated with preterm birth is high.     

Pregnancy and long-term cardiovascular outcomes in women with congenitally corrected transposition of the great arteries

Objective

To define maternal/neonatal outcomes and long-term cardiovascular effects of pregnancy in women with congenitally corrected transposition of the great arteries (ccTGA).

Methods

Clinical records of all women with ccTGA who were followed at a tertiary care center in Poland between April 1991 and April 2012 were retrospectively reviewed.

Results

Of the 20 pregnancies among 13 women identified, 19 (95%) were successful. Of the 19 deliveries, 14 (74%) were vaginal and 5 (26%) were cesarean. Cardiovascular complications during pregnancy and childbirth occurred in 3 patients (16% of successful pregnancies). Two women developed supraventricular arrhythmias; they were observed and required no pharmacologic treatment. One patient required premature delivery for documented deterioration of right ventricular function. There were no pregnancy-related maternal deaths. In 1 case, congenital heart disease was diagnosed in the offspring. With regard to long-term follow-up, no differences were found in terms of heart failure admissions, pharmacologic treatment, deaths, or echocardiographic parameters compared with non-pregnant women with ccTGA.

Conclusion

Successful pregnancy can be achieved by most women with ccTGA. The most common cardiovascular complications are supraventricular arrhythmias but pregnancy does not seem to impair right ventricular function in the long term. Nevertheless, preconception counseling and tertiary care during pregnancy for women with ccTGA are recommended.     

Improving the maternal mortality ratio in Zhejiang Province,China, 1988–2008

Objective

maternal mortality remains a major public health problem in many countries. The aim of this paper is to describe the progress made in maternal health care in Zhejiang Province, China over 20 years in reducing the maternal mortality ratio (MMR).

Setting

Zhejiang Province is located on the mid-east coast of China, approximately 180 km south of Shanghai, and has a population of 49 million. Almost all mothers give birth in hospitals or maternal and infant health institutes.

Method

the annual maternal death audit reports from 1988 to 2008 were analysed. These reports were prepared annually by the Zhejiang Prenatal Health Committee after auditing each individual case.

Measurements and findings

China has made considerable progress in reducing the MMR. Zhejiang has one of fastest developing economies in China, and since the 86 economic reforms of 1978, health care has improved rapidly and the MMR has declined. During the 1988–2008 period, 2258 maternal deaths were reported from 8,880,457 live births. During these two decades, the MMR decreased dramatically from 48.50 in 1988 to 6.57 per 100,000 in 2008. The MMR in migrant women dropped from 66.87 in 2003 to 21.67 per 100,000 in 2008. The rate of decline was more rapid in rural areas than in the city. There has been a decline in the proportion of deaths with direct obstetric causes and a corresponding increase in the proportion of indirect causes. The proportion of deaths classified as preventable has declined in the past two decades. Social factors are important in maternal safety, and on average 26.8% of maternal deaths were influenced by these factors.

Conclusion

as the economy was developing, maternal safety was made a priority health issue by the Government and health workers. The provincial MMR has dropped rapidly and is now similar to the rates in developed countries and lower than that in the USA. However, more work is still needed to ensure that all mothers, including migrant workers, continue to have these low rates.     

Geographic accessibility to obstetric care and maternal mortality in a large metropolitan area of Brazil

Objective

To assess maternal mortality and its association with accessibility to obstetric care in the metropolitan region of Rio de Janeiro, Brazil.

Methods

Maternal mortality was assessed from 2 national databases, one administrative and the other designed for epidemiologic purposes. Distances traveled from residence to hospital via the transit network were calculated using a specialized information system. Deaths were grouped by area of residence, and maternal mortality ratios (number of deaths per 100,000 live births) as well as death incidence ratios (deaths/live births in 2 regions or hospital types) were calculated for these areas.

Results

We identified 236 deaths and estimated under-reporting at 30%. The most common causes of death were hypertension-related disorders, “other obstetric conditions,” and complications from abortion; the longest traveled distance was 66.43 km (mean, 13.65 km); and maternal mortality ratios varied between 25.54% and 56.45%, the highest values being for areas with the lowest municipal human development index. The highest death incidence ratios were found at general hospitals without specialized obstetric care.

Conclusion

Maternal mortality is still a serious problem in the studied region. The wide variations among areas of different socioeconomic conditions suggest the need for a better allocation of health care resources.     

Excess of maternal mortality in foreign nationalities in Spain, 1999–2006

Objective

This study aimed to compare maternal mortality by province, autonomous region and mother's country of birth in Spain during 1999–2006.

Study design

A cross-sectional ecological study with all live births and maternal mortality cases occurring during 1999–2006 in Spain was done. Data were drawn from the National Statistics Institute (INE) and we used the Movement of Natural Persons (MNP) and death statistics broken down by cause of death. Maternal mortality rates by province, autonomous region and mother's country of birth were calculated. To compare maternal mortality by province, standardised mortality ratios were calculated using an indirect standardisation. The risk of maternal death by autonomous region, age and mother's country of birth was calculated by a Poisson regression.

Results

Sub-Saharan nationalities present the highest maternal mortality rates. Adjusted by age and autonomous region, foreign nationalities had 67% higher risk of maternal mortality (RR = 1.67; 95%CI = 1.22–2.33). Adjusted by mother's country of birth and age, two autonomous regions had a significant mortality excess: Andalusia (RR = 1.84; 95%CI = 1.32–2.57) and Asturias (RR = 2.78 95%CI = 1.24–6.24).

Conclusion

This study shows inequalities in maternal mortality by province, autonomous region and mother's country of birth in Spain. It would be desirable to implement a maternal mortality active surveillance system and the use of confidential qualitative surveys for analysis of socio-economic and healthcare circumstances surrounding deaths. These measures would be invaluable for in-depth understanding and characterisation of a preventable phenomenon such as maternal death.     

Perinatal mortality rate in the Netherlands compared to other European countries: A secondary analysis of Euro-PERISTAT data

Objective

the poor perinatal mortality ranking of the Netherlands compared to other European countries has led to questioning the safety of primary care births, particularly those at home. Primary care births are only planned at term. We therefore examined to which extent the perinatal mortality rate at term in the Netherlands contributes to its poor ranking.

Design

secondary analyses using published data from the Euro-PERISTAT study.

Setting and participants

women that gave birth in 2004 in the 29 European regions and countries called 'countries' included in the Euro-PERISTAT study (4,328,441 women in total and 1,940,977 women at term).

Methods

odds ratios and 95% confidence intervals were calculated for the comparison of perinatal mortality rates between European countries and the Netherlands, through logistic regression analyses using summary country data.

Main outcome measures

combined perinatal mortality rates overall and at term. Perinatal deaths below 28 weeks, between 28 and 37 weeks and from 37 weeks onwards per 1000 total births.

Findings

compared to the Netherlands, perinatal mortality rates at term were significantly higher for Denmark and Latvia and not significantly different compared to seven other countries. Eleven countries had a significantly lower rate, and for eight the term perinatal mortality rate could not be compared. The Netherlands had the highest number of perinatal deaths before 28 weeks per 1000 total births (4.3).

Key conclusions

the relatively high perinatal mortality rate in the Netherlands is driven more by extremely preterm births than births at term. Although the PERISTAT data cannot be used to show that the Dutch maternity care system is safe, neither should they be used to argue that the system is unsafe. The PERISTAT data alone do not support changes to the Dutch maternity care system that reduce the possibility for women to choose a home birth while benefits of these changes are uncertain.
