An analysis of maternal deaths in British Columbia: 1963 to 1970

There were 132 maternal deaths in British Columbia in the years 1963 to 1970. The mean maternal mortality rate for these eight years was 0.317. Sixty of these deaths (45.5%) were due to direct obstetrical causes. Indirect and nonrelated deaths accounted for 21.2 and 33.3% of the total, respectively. The most common causes of direct obstetrical deaths were hemorrhage, infection and vascular accidents, in that order; pre-eclampsia ranked a distant fourth. Ninety-five percent of direct obstetrical deaths were probably avoidable. Approximately 27% of all direct obstetrical deaths were abortion-related. Hemorrhage continues to be a major problem, in particular among the native Indian women of the province.If further reduction in maternal mortality is to be achieved, obstetrical hemorrhage must be better managed and deaths due to abortions reduced. Future studies should reveal if the liberalized abortion laws will assist in the realization of the latter goal.     

Surveillance system of maternal mortality in the Tunis region

In the framework of a national strategy of reduction of the maternal mortality rate. Tunisia has set up a follow up system of maternal deaths occurring in public facilities to analyse their causes, the levels of deficiency and to propose solutions for preventing them. This note aims at describing the system, its results, its efficiency and its limitations in the Tunis region for the years 1999 and 2000. The results show a maternal mortality rate estimated at 80 for 100,000 births in public facilities of the region: the main causes being haemorrhage (42.1%) followed by infection (13.2%). The proportion of avoidable deaths is 87%:74% possibly avoidable and 13% certainly avoidable, factors related to women behaviour have also contributed to 45% of cases. The system flows are however intricated, and related to organization: an underestimation of risk by the patient (33%), an inadequate watch during the postpartum period (25%), a late hospitalisation (22%) and not enough reanimation equipment. Nevertheless, this control system has achieved part of its objective by starting up a quality approach to obstetrical cares and by warning health professionals such as obstetricians, anaesthetists, blood banks in charge, hospital managers and other medical teams. The limitations of the system are tied to the follow up of the real implementation of recommendations stated in reports at a local as well as central levels.     

MATERNAL AND PERINATAL DEATHS IN CALIFORNIA

In a 29-month period, 151 of 373 deaths of California women occurring during or within 90 days of termination of pregnancy were studied jointly by the California Medical Association and the California State Department of Public Health. Twenty-two per cent of the deaths reviewed were considered unavoidable. In 74 per cent, one or more avoidable factors were identified. Avoidable factors could not be identified in 4 per cent of the cases.Thirty-three per cent of the cases considered to have avoidable factors were attributed to be solely the responsibility of the attending physician. Inadequate hospital facilities were held responsible in less than 1 per cent of deaths, while responsibility in 26 per cent of the deaths was laid directly to patient error or refusal. In 40 per cent of the avoidable deaths, more than one avoidable factor was identified.Nonobstetric conditions accounted for the greatest proportion of the deaths, followed by hemorrhage, toxemia of pregnancy, sepsis, abortion and ectopic pregnancy.The findings of this study compare closely with those of similar studies in other states, including Minnesota and Massachusetts.     

Spontaneous rupture of a previously scared uterus. A case report and an overview of risk factors in Yemen Republic

Maternal mortality is a significant public health problem. In Yemen it is attributable to socioeconomic, reproductive, health-status and health-services factors, as well as to medical causes. Direct obstetrical causes account for 61% of maternal deaths in Yemen 75% after delivery. Hemorrhage has been found as the second cause of maternal death in Yemen, accounting for 23.68% of all causes, while ruptured uterus accounts for 14.19% of maternal deaths in particular. The high percentage of ruptured uterus as a cause of maternal mortality prompted me to report the case below hoping it would shed light on the influence of factors, which can lead to this serious situations in Yemen.     

Maternal Mortality in California

During the period August 1957 to December 1966, the Committee on Maternal and Child Care of the California Medical Association and the State Department of Public Health studied 1,219 deaths of women who died during or within 90 days of termination of pregnancy. Twenty-two percent of the deaths reviewed were considered unavoidable. Seventy percent had one or more avoidable factors; of these, 46 percent were attributed to errors in professional judgment, and 16 percent to inadequate prenatal care by the patient herself.Nearly one-third (383) of the 1,219 cases reviewed were deaths from non-obstetric causes. Of the 836 deaths from obstetric causes, 260 were attributed to abortion. Preliminary figures suggest a reduction in criminal abortion deaths corresponding to the increase in therapeutic abortions since 1968.Over one-third of the deaths occurred in Mexican and Negro mothers. Death rate for Negro was triple that for white mothers. Despite the presence of four medical schools in District II (Los Angeles County), maternal death rates were 30 to 50 percent higher than in other districts due to the large urban black and Chicano population. One rural district with a large migratory agricultural population also had high rates.     

Local confidential inquiry into avoidable factors in deaths from stroke and hypertensive disease.

OBJECTIVE--To audit avoidable deaths from stroke and hypertensive disease. DESIGN--Details of care before death were obtained from general practitioners and other doctors, anonymised, and assessed by two experts against agreed minimum standards of good practice for detecting and managing hypertension. SETTING--Health authority with population of 250,000. SUBJECTS--All patients under 75 years who died of stroke, hypertensive disease, or hypertension related causes during November 1990 to October 1991. MAIN OUTCOME MEASURES--Presence of important avoidable factors and departures from minimum standards of good practice. RESULTS--Adequate information was obtained for 88% (123/139) of eligible cases. Agreement between the assessors was mostly satisfactory. 29% (36/123, 95% confidence interval 21% to 37%) of all cases and 44% (36/81, 34% to 55%) of those with definite hypertension had avoidable factors that may have contributed to death. These were most commonly failures of follow up and continuing smoking. Assessment against standards of minimum good practice showed that care was inadequate but not necessarily deemed to have contributed to death, in a large proportion of patients with definite hypertension. Common shortcomings were inadequate follow up, clinical investigation, and recording of smoking and other relevant risk behaviours. CONCLUSIONS--This method of audit can identify shortcomings in care of patients dying of hypertension related disease.     

AN EVALUATION OF CESAREAN SECTION

The risks of cesarean section have been reduced in step with the increase in safety of all major surgical procedures.In a series of 13,153 deliveries, 1,265 (9.6 per cent) were by cesarean section. There were three obstetrical maternal deaths in 11,888 cases in which delivery was by the vaginal route—0.025 per cent. In the series of 1,265 deliveries by cesarean section there was one death attributable to the operation—0.08 per cent.The total uncorrected fetal loss following cesarean section was 3.8 per cent. This compares favorably with fetal loss of 3.2 per cent in the vaginal delivery group in this series, and with fetal loss rates reported from large obstetrical centers.Anesthesia by spinal injection is the method of choice in cesarean section. There were no maternal deaths or accidents attributable to spinal anesthetic, and in no case was it felt that fetal death was attributable to it.The incidence of maternal morbidity in the cesarean section group following spinal anesthesia was 15.8 per cent—less than half the incidence of morbidity following inhalation anesthesia.     

Snowmobile-related deaths in Ontario: a 5-year review.

OBJECTIVES: To investigate the demographic characteristics and circumstances surrounding fatal snowmobile accidents in Ontario, to examine the risk factors and to observe any fatality trends over the study period. DESIGN: Case series. PATIENTS: All 131 people who died accidentally while operating a snowmobile in Ontario from 1985-86 to 1989-90. Records were obtained from the chief coroner''s office; registration data were obtained from the Ministry of Transportation. RESULTS: Although the absolute number of deaths increased each year, owing to a rapid increase in the number of registered snowmobiles, the risk of death from snowmobile accidents remained relatively constant. Deaths occurred most frequently in northeastern Ontario. Youths and men predominated among the victims. Fatal accidents occurred more often on lakes (in 66% of the cases in which this information was known) than on roads (in 26%) or trails (in 8%). Weekend fatalities predominated, and deaths occurred most often during times of suboptimal lighting (from 4 pm to 8 am). The driver was killed in 84% of the cases in which the person''s role was known. Alcohol use before death was implicated in 69% of the cases, the level exceeding the Ontario legal limit in 59%. CONCLUSION: Snowmobile-related deaths result from factors that are generally avoidable. Strategies need to be instituted to reduce the rate of these events.     

The University of Manitoba Follow-up Study: A Prospective Investigation of Cardiovascular Disease: Part I. General Description—Mortality and Incidence of Coronary Heart Disease

A prospective study of cardiovascular disease was initiated in 1946 whereby 3983 healthy North American males, 91% under age 40, were subjected to periodic electrocardiograms and medical examinations between 1948 and 1963. The health of all but five of the 3773 survivors was known in 1963. There were 210 deaths: aircraft accidents accounted for 45%, cardiovascular disease 20%, cancer 11% and other causes 23%. The aggregate mortality closely resembled that of the Canadian Life Table 1955-57 (Male). Extra deaths were observed under age 40 owing to a high frequency of flying accidents. At older ages the mortality was lower than expected because congenital and chronic diseases were excluded at entry. One hundred and forty-three developed coronary heart disease. The case fatality rate was 31%. The incidence rate for coronary heart disease rose progressively from 0.277 per thousand per year for ages 25-34 to 26.5 at ages 60-69.     

Maternal and Antenatal Risk Factors for Stillbirths and Neonatal Mortality in Rural Bangladesh: A Case-Control Study

Objective

To identify maternal and antenatal factors associated with stillbirths and neonatal deaths in rural Bangladesh.

Study Design

A prospective cohort study is being conducted to evaluate a maternal and child nutrition program in rural Bangladesh. Cases were all stillbirths and neonatal deaths that occurred in the cohort between March 7, 2011 and December 30, 2011. Verbal autopsies were used to determine cause of death. For each case, four controls were randomly selected from cohort members alive at age 3-months. Multivariable logistic regression was used to identify factors associated with these deaths.

Results

Overall, 112 adverse pregnancy outcomes (44 stillbirths, 19/1,000 births; 68 neonatal deaths, 29/1,000 live births) were reported. Of the stillbirths 25 (56.8%) were fresh. The main causes of neonatal death were birth asphyxia (35%), sepsis (28%) and preterm birth (19%). History of bleeding during pregnancy was the strongest risk factor for stillbirths (adjusted odds ratio 22.4 [95% confidence interval 2.5, 197.5]) and neonatal deaths (adjusted odds ratio 19.6 [95% confidence interval 2.1, 178.8]). Adequate maternal nutrition was associated with decreased risk of neonatal death (adjusted odds ratio 0.4 [95% confidence interval 0.2, 0.8]).

Conclusions

Identifying high-risk pregnancies during gestation and ensuring adequate antenatal and obstetric care needs to be a priority for any community-based maternal and child health program in similar settings.     

Unnatural deaths in South African platinum miners, 1992-2008

Background

The mortality rate from unnatural deaths for South Africa is nearly double the world average. Reliable data are limited by inaccurate and incomplete ascertainment of specific causes of unnatural death. This study describes trends in causes of unnatural death between 1992 and 2008 in a cohort of South African miners.

Methodology/Principal Findings

The study used routinely-collected retrospective data with cause of death determined from multiple sources including the mine''s human resources database, medical records, death registration, and autopsy. Cause-specific mortality rates and Poisson regression coefficients were calculated by calendar year and age group. The cohort included 40,043 men. One quarter of all 2937 deaths were from unnatural causes (n = 805). Causes of unnatural deaths were road traffic accidents 38% (109/100,000 py), homicides 30% (88/100,000 py), occupational injuries 17% (50/100,000 py), suicides 8% (24/100,000 py), and other accidents 6% (19/100,000 py). Rates of unnatural deaths declined by 2% (95%CI -4%,-1%) per year over the study period, driven by declining rates of road traffic and other accidents. The rate of occupational injury mortality did not change significantly over time (-2% per year, 95%CI -5%,+2%). Unnatural deaths were less frequent in this cohort of workers than in the South African population (IRR 0.89, 95%CI 0.82–0.95), particularly homicides (IRR 0.48, 95%CI 0.42–0.55).

Conclusions/Significance

Unnatural deaths were a common cause of preventable and premature death in this cohort of miners. While unnatural death rates declined between 1992 and 2008, occupational fatalities remained at a high level. Evidence-based prevention strategies to address these avoidable deaths are urgently needed.     

Controlled investigation of deaths from asthma in hospitals in the North East Thames region.

One hundred and thirty deaths definitely or potentially due to asthma occurring in hospitals in the North East Thames region over one year were identified from death certificates and Hospital Activity Analysis records. Thirty five of these deaths were considered after independent assessment to have been directly due to asthma. Control patients who left hospital alive after acute asthma attacks were selected and matched with cases for sex, age, and hospital. Management was compared in the two groups. Inadequate monitoring, including failure to monitor arterial blood gas values, and inadequate use of nebulised beta agonists occurred significantly more often in fatal cases. Use of sedation, inadequate treatment with steroids, exposure to potentially toxic doses of aminophylline, and inadequate clinical assessment were more common in cases than controls, but not significantly so. Failure to institute artificial ventilation contributed to seven deaths. Assessors considered important defects in management to have occurred in 83% (29/35) of the cases and 40% (14/35) of the controls. Nevertheless, most of the hospital deaths (19/35) were considered not to have been preventable. Eight other deaths in the region were attributed to the complications of asthma or its treatment. Three of these were associated with gastrointestinal bleeding and one with perforation of a duodenal ulcer. Before considering policies aimed at speeding admission to hospital of patients with acute attacks of asthma it is crucial that the general standard of hospital care offered to all patients with asthma should be improved.     

Premature Adult Death in Individuals Born Preterm: A Sibling Comparison in a Prospective Nationwide Follow-Up Study

BackgroundClose to one in ten individuals worldwide is born preterm, and it is important to understand patterns of long-term health and mortality in this group. This study assesses the relationship between gestational age at birth and early adult mortality both in a nationwide population and within sibships. The study adds to existing knowledge by addressing selected causes of death and by assessing the role of genetic and environmental factors shared by siblings.MethodsStudy population was all Norwegian men and women born from 1967 to 1997 followed using nation-wide registry linkage for mortality through 2011 when they were between 15 and 45 years of age. Analyses were performed within maternal sibships to reduce variation in unobserved genetic and environmental factors shared by siblings. Specific outcomes were all-cause mortality and mortality from cardiovascular diseases, cancer and external causes including accidents, suicides and drug abuse/overdoses.ResultsCompared with a sibling born in week 37–41, preterm siblings born before 34 weeks gestation had 50% increased mortality from all causes (adjusted Hazard Ratio (aHR) 1.54, 95% confidence interval (CI) 1.17, 2.03). The corresponding estimate for the entire population was 1.27 (95% CI 1.09, 1.47). The majority of deaths (65%) were from external causes and the corresponding risk estimates for these deaths were 1.52 (95% CI 1.08, 2.14) in the sibships and 1.20 (95% CI 1.01, 1.43) in the population.ConclusionPreterm birth before week 34 was associated with increased mortality between 15 and 45 years of age. The results suggest that increased premature adult mortality in this group is related to external causes of death and that the increased risks are unlikely to be explained by factors shared by siblings.     

Maternal age and non‐chromosomal birth defects,Atlanta—1968–2000: Teenager or thirty‐something,who is at risk?

OBJECTIVE: This investigation explored the association between maternal age and non-chromosomal birth defects to assess any increased risk associated with maternal age. METHODS: Birth defect cases were ascertained by the Metropolitan Atlanta Congenital Defects Program (MACDP), denominator information was obtained using birth certificate data. Infants with any chromosomal diagnosis were excluded. Effect estimates were calculated using 5-year maternal age categories with 25-29 years as the referent. Multiple logistic regression was used to adjust for maternal race, parity, infant sex, and birth year. RESULTS: A total of 1,050,616 singleton infants, born after > or = 20 weeks gestation in the five counties of metropolitan Atlanta from 1968 through 2000 who did not have a chromosomal abnormality and whose mother was 14 to 40 years old, were included in the analyses, 32,816 of them were identified with birth defects by the MACDP. Young maternal age (14-19 years) was associated with anencephaly (OR = 1.81, 95% CI = 1.30-2.52), hydrocephaly without neural tube defect (OR = 1.56, 95% CI = 1.23-1.96), all ear defects (OR = 1.28, 95% CI = 1.10-1.49), cleft lip (OR = 1.88, 95% CI = 1.30-2.73), female genital defects (OR = 1.57, 95% CI = 1.12-2.19), hydronephrosis (OR = 1.42, 95% CI = 1.11-1.82), polydactyly (OR = 1.29, 95% CI = 1.09-1.52), omphalocele (OR = 2.08, 95% CI = 1.39-3.12), and gastroschisis (OR = 7.18, 95% CI = 4.39-11.75). Advanced maternal age (35-40 years) was associated with all heart defects (OR = 1.12, 95% CI = 1.03-1.22), tricuspid atresia (OR = 1.24, 95% CI = 1.02-1.50), right outflow tract defects (OR = 1.28, 95% CI = 1.10-1.49), hypospadias 2nd degree or higher (OR = 1.85, 95% CI = 1.33-2.58), male genital defects excluding hypospadias (OR = 1.25, 95% CI = 1.08-1.45) and craniosynostosis (OR = 1.65, 95% CI = 1.18-2.30). CONCLUSIONS: Young and advanced maternal ages are associated with different types of birth defects. Underlying causes for these associations are not clear.     

Maternal mortality in British Columbia in 1971-86.

We reviewed the 56 maternal deaths in British Columbia in 1971-78 and 1979-86 identified through the provincial Ministry of Health and compared the findings with data for the two preceding 8-year periods. The maternal death rate, defined as the number of deaths directly or indirectly related to pregnancy or delivery per 100,000 live births, decreased from 42 in 1955-62 to 5 in 1979-86. In the same interval the number of direct obstetric deaths decreased from 100 to 10 and the number of indirect deaths from 29 to 8. The number of deaths due to abortion decreased from 32 to 1. There was no change in the number of deaths among North American Indians. There was also no change in the number of deaths due to hypertension, most of which were avoidable; these findings have stimulated intensive teaching efforts to increase recognition and improve management of the problem. Review of maternal deaths can help identify deficiencies in the quality of care and can direct measures aimed at further reducing the maternal death rate.     

Maternal Mortality in Taiwan: A Nationwide Data Linkage Study

Background

To examine the changes in the maternal mortality ratio (MMR) and causes of maternal death in Taiwan based on nationwide linked data sets.

Methods

We linked four population-based data sets (birth registration, birth notification, National Health Insurance inpatient claims, and cause of death mortality data) to identify maternal deaths for 2004–2011. Subsequently, we calculated the MMR (deaths per 100,000 live births) and the proportion of direct and indirect causes of maternal death by maternal age and year.

Findings

Based on the linked data sets, we identified 236 maternal death cases, of which only 102 were reported in officially published mortality data, with an underreporting rate of 57% [(236−102) × 100 / 236]. The age-adjusted MMR was 18.4 in 2004–2005 and decreased to 12.5 in 2008–2009; however, the MMR leveled off at 12.6 in 2010–2011. The MMR increased from 5.2 in 2008–2009 to 7.1 in 2010–2011 for patients aged 15–29 years. Women aged 15–29 years had relatively lower proportion in dying from direct causes (amniotic fluid embolism and obstetric hemorrhage) compared with their counterpart older women.

Conclusions

Approximately two-thirds of maternal deaths were not reported in officially published mortality data. Routine surveillance of maternal mortality by using enhanced methods is necessary to monitor the health status of reproductive-age women. Furthermore, a comprehensive maternal death review is necessary to explore the preventability of these maternal deaths.     

Enhancing Maternal and Perinatal Health in Under-Served Remote Areas in Sub-Saharan Africa: A Tanzanian Model

Background

In Tanzania, maternal mortality ratio (MMR), unmet need for emergency obstetric care and health inequities across the country are in a critical state, particularly in rural areas. This study was established to determine the feasibility and impact of decentralizing comprehensive emergency obstetric and neonatal care (CEmONC) services in underserved rural areas using associate clinicians.

Methods

Ten health centres (HCs) were upgraded by constructing and equipping maternity blocks, operating rooms, laboratories, staff houses and installing solar panels, standby generators and water supply systems. Twenty-three assistant medical officers (advanced level associate clinicians), and forty-four nurse-midwives and clinical officers (associate clinicians) were trained in CEmONC and anaesthesia respectively. CEmONC services were launched between 2009 and 2012. Monthly supportive supervision and clinical audits of adverse pregnancy outcomes were introduced in 2011 in these HCs and their respective district hospitals.

Findings

After launching CEmONC services from 2009 to 2014 institutional deliveries increased in all upgraded rural HCs. Mean numbers of monthly deliveries increased by 151% and obstetric referrals decreased from 9% to 3% (p = 0.03) in HCs. A total of 43,846 deliveries and 2,890 caesarean sections (CS) were performed in these HCs making the mean proportion of all births in EmONC facilities of 128% and mean population-based CS rate of 9%. There were 190 maternal deaths and 1,198 intrapartum and very early neonatal deaths (IVEND) in all health facilities. Generally, health centres had statistically significantly lower maternal mortality ratios and IVEND rates than district hospitals (p < 0.00 and < 0.02 respectively). Of all deaths (maternal and IVEND) 84% to 96% were considered avoidable.

Conclusions

These findings strongly indicate that remotely located health centres in resource limited settings hold a great potential to increase accessibility to CEmONC services and to improve maternal and perinatal health.     

Years of Life Lost (YLL) in Colombia 1998-2011: Overall and Avoidable Causes of Death Analysis

ObjectiveEstimate the Years of Life Lost (YLL) for overall and avoidable causes of death (CoD) in Colombia for the period 1998-2011.MethodsFrom the reported deaths to the Colombian mortality database during 1998-2011, we classified deaths from avoidable causes. With the reference life table of the Global Burden of Disease (GBD) 2010 study, we estimated the overall YLL and YLL due to avoidable causes. Calculations were performed with the difference between life expectancy and the age of death. Results are reported by group of cause of death, events, sex, year and department. Comparative analysis between number of deaths and YLL was carried out.ResultsA total of 83,856,080 YLL were calculated in Colombia during period 1998-2011, 75.9% of them due to avoidable CoD. The year 2000 reported the highest number of missed YLL by both overall and avoidable CoD. The departments with the highest YLL rates were Caquetá, Guaviare, Arauca, Meta, and Risaralda. In men, intentional injuries and cardiovascular and circulatory diseases had the higher losses, while in women YLL were mainly due to cardiovascular and circulatory diseases.ConclusionsThe public health priorities should focus on preventing the loss of YLL due to premature death and differentiated interventions by sex.     

Deaths of cyclists in London 1985-92: the hazards of road traffic.

OBJECTIVE--To determine the characteristics of cyclists and vehicles involved in fatal cycling accidents. DESIGN--Analysis of data routinely collected by police for each accident from January 1985 to December 1992 and held in a national master file (Stats 19) by the Department of Transport. SETTING--Greater London, which comprises inner London (12 boroughs and the City of London) and outer London (20 boroughs). SUBJECTS--178 cyclists who died (78 in inner London and 100 in outer London; age range 3-88). MAIN OUTCOME MEASURES--Associations between characteristics of cyclists, type of vehicle involved, and place of accident. RESULTS--Motor vehicles were involved in 173 deaths. Heavy goods vehicles were involved in 75 deaths (30/100 (30%) in outer London and 45/78 (58%) in inner London); cars in 74 (54/100) (54%) in outer London and 20/78 (26%) in inner London); light goods vehicles in 12/178 (7%); and buses in 6/178 (3%). Thirty five of the people who died were children aged < or = 16. Female cyclists were especially at risk from heavy goods vehicles in inner London (22 deaths), while male cyclists were especially at risk from cars in outer London (50 deaths). DISCUSSION--Cyclists who died in urban areas are more likely to be adults than children. In inner London, in relation to their traffic volume, heavy goods vehicles are estimated to cause 30 times as many cyclists'' deaths as cars and five times as many as buses. Until the factors leading to this excess risk are understood, a ban on heavy goods vehicles in urban areas should be considered.     

Maternal and Neonatal Mortality in South-West Ethiopia: Estimates and Socio-Economic Inequality

Introduction

Ethiopia has achieved the fourth Millennium Development Goal by reducing under 5 mortality. Nevertheless, there are challenges in reducing maternal and neonatal mortality. The aim of this study was to estimate maternal and neonatal mortality and the socio-economic inequalities of these mortalities in rural south-west Ethiopia.

Methods

We visited and enumerated all households but collected data from those that reported pregnancy and birth outcomes in the last five years in 15 of the 30 rural kebeles in Bonke woreda, Gamo Gofa, south-west Ethiopia. The primary outcomes were maternal and neonatal mortality and a secondary outcome was the rate of institutional delivery.

Results

We found 11,762 births in 6572 households; 11,536 live and 226 stillbirths. There were 49 maternal deaths; yielding a maternal mortality ratio of 425 per 100,000 live births (95% CI:318–556). The poorest households had greater MMR compared to richest (550 vs 239 per 100,000 live births). However, the socio-economic factors examined did not have statistically significant association with maternal mortality. There were 308 neonatal deaths; resulting in a neonatal mortality ratio of 27 per 1000 live births (95% CI: 24–30). Neonatal mortality was greater in households in the poorest quartile compared to the richest; adjusted OR (AOR): 2.62 (95% CI: 1.65–4.15), headed by illiterates compared to better educated; AOR: 3.54 (95% CI: 1.11–11.30), far from road (≥6 km) compared to within 5 km; AOR: 2.40 (95% CI: 1.56–3.69), that had three or more births in five years compared to two or less; AOR: 3.22 (95% CI: 2.45–4.22). Households with maternal mortality had an increased risk of stillbirths; OR: 11.6 (95% CI: 6.00–22.7), and neonatal deaths; OR: 7.2 (95% CI: 3.6–14.3). Institutional delivery was only 3.7%.

Conclusion

High mortality with socio-economic inequality and low institutional delivery highlight the importance of strengthening obstetric interventions in rural south-west Ethiopia.
