Maternal health interventions in resource limited countries: a systematic review of packages, impacts and factors for change

BackgroundThe burden of maternal mortality in resource limited countries is still huge despite being at the top of the global public health agenda for over the last 20 years. We systematically reviewed the impacts of interventions on maternal health and factors for change in these countries.MethodsA systematic review was carried out using the guidelines for Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Articles published in the English language reporting on implementation of interventions, their impacts and underlying factors for maternal health in resource limited countries in the past 23 years were searched from PubMed, Popline, African Index Medicus, internet sources including reproductive health gateway and Google, hand-searching, reference lists and grey literature.ResultsOut of a total of 5084 articles resulting from the search only 58 qualified for systematic review. Programs integrating multiple interventions were more likely to have significant positive impacts on maternal outcomes. Training in emergency obstetric care (EmOC), placement of care providers, refurbishment of existing health facility infrastructure and improved supply of drugs, consumables and equipment for obstetric care were the most frequent interventions integrated in 52% - 65% of all 54 reviewed programs. Statistically significant reduction of maternal mortality ratio and case fatality rate were reported in 55% and 40% of the programs respectively. Births in EmOC facilities and caesarean section rates increased significantly in 71% - 75% of programs using these indicators. Insufficient implementation of evidence-based interventions in resources limited countries was closely linked to a lack of national resources, leadership skills and end-users factors.ConclusionsThis article presents a list of evidenced-based packages of interventions for maternal health, their impacts and factors for change in resource limited countries. It indicates that no single magic bullet intervention exists for reduction of maternal mortality and that all interventional programs should be integrated in order to bring significant changes. State leaders and key actors in the health sectors in these countries and the international community are proposed to translate the lessons learnt into actions and intensify efforts in order to achieve the goals set for maternal health.

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.

Eclampsia in the Netherlands

OBJECTIVE: The incidence of maternal mortality due to hypertensive disorders of pregnancy in the Netherlands is greater than in other Western countries. We aimed to confirm and explain this difference by assessing incidence, risk factors, and substandard care of eclampsia in the Netherlands. METHODS: In a nationwide population-based cohort study, all cases of eclampsia were prospectively collected during a 2-year period (2004–2006). All pregnant women in the Netherlands in the same period acted as reference cohort (n=371,021). Substandard care was assessed in all cases. A selection of cases was extensively audited by an expert panel. Main outcome measures were incidence, case fatality rate, possible risk factors, and substandard care. RESULTS: All 98 Dutch maternity units participated (100%). There were 222 cases of eclampsia, for an incidence of 6.2 per 10,000 deliveries. Three maternal deaths occurred; the case fatality rate was 1 in 74. Risk factors in univariable analysis included multiple pregnancy, primiparity, young age, ethnicity, and overweight. Prophylactic magnesium sulfate was given in 10.4% of women, and antihypertensive medication was given in 39.6% of women with a blood pressure on admission at or above 170/110 mm Hg. Additionally, substandard care was judged to be present by an expert panel in 15 of 18 audited cases (83%). CONCLUSION: The incidence of eclampsia in the Netherlands is markedly increased as compared with other Western European countries. Substandard care was identified in many cases, indicating the need for critical evaluation of the management of hypertensive disease in the Netherlands. LEVEL OF EVIDENCE: II

Amniotic fluid embolism incidence, risk factors and outcomes: a review and recommendations

BackgroundAmniotic fluid embolism (AFE) is a rare but severe complication of pregnancy. A recent systematic review highlighted apparent differences in the incidence, with studies estimating the incidence of AFE to be more than three times higher in North America than Europe. The aim of this study was to examine population-based regional or national data from five high-resource countries in order to investigate incidence, risk factors and outcomes of AFE and to investigate whether any variation identified could be ascribed to methodological differences between the studies.MethodsWe reviewed available data sources on the incidence of AFE in Australia, Canada, the Netherlands, the United Kingdom and the USA. Where information was available, the risk factors and outcomes of AFE were examined.ResultsThe reported incidence of AFE ranged from 1.9 cases per 100 000 maternities (UK) to 6.1 per 100 000 maternities (Australia). There was a clear distinction between rates estimated using different methodologies. The lowest estimated incidence rates were obtained through validated case identification (range 1.9-2.5 cases per 100 000 maternities); rates obtained from retrospective analysis of population discharge databases were significantly higher (range 5.5-6.1 per 100 000 admissions with delivery diagnosis). Older maternal age and induction of labour were consistently associated with AFE.ConclusionsRecommendation 1: Comparisons of AFE incidence estimates should be restricted to studies using similar methodology. The recommended approaches would be either population-based database studies using additional criteria to exclude false positive cases, or tailored data collection using existing specific population-based systems.Recommendation 2: Comparisons of AFE incidence between and within countries would be facilitated by development of an agreed case definition and an agreed set of criteria to minimise inclusion of false positive cases for database studies.Recommendation 3: Groups conducting detailed population-based studies on AFE should develop an agreed strategy to allow combined analysis of data obtained using consistent methodologies in order to identify potentially modifiable risk factors.Recommendation 4: Future specific studies on AFE should aim to collect information on management and longer-term outcomes for both mothers and infants in order to guide best practice, counselling and service planning.

Maternal mortality and severe morbidity from sepsis in the Netherlands.

Objective. To assess incidence and risk factors of maternal mortality and severe morbidity from sepsis in the Netherlands. Design. A nationwide confidential enquiry into maternal mortality from 1993 to 2006 and severe maternal morbidity from 2004 to 2006. Setting. All 98 Dutch maternity units in the Netherlands. Population. All pregnant women in the Netherlands from 1993 to 2006. Methods. All reported cases of maternal death from sepsis during 1993–2006 were reported to the Maternal Mortality Committee. Cases of severe maternal morbidity from sepsis from 2004 to 2006 were collected in a nationwide design. Main outcome measures. Incidence, case fatality rates, and possible risk factors. Results. The maternal mortality ratio from direct maternal mortality from sepsis was 0.73 per 100,000 live births (20/2,742,265). The incidence of severe maternal morbidity from sepsis was 21 per 100,000 deliveries (78/371,021), of which 79% was admitted to the intensive care unit. High age, multiple pregnancies, and the use of artificial reproduction techniques were significant risk factors for developing sepsis in univariate analysis. The overall case fatality rate for sepsis during 2004–2006 was 7.7% (6/78). Group A streptococcal infection was in 42.9% (9/21), the cause of direct maternal mortality from sepsis (1993–2006). In 31.8% (14/44), Group A streptococcal infection was the cause of obstetric morbidity from sepsis (2004–2006). Conclusions. With a case fatality rate of 7.7%, sepsis is a life threatening condition for women during pregnancy, childbirth, and puerperium.

Reduction of severe acute maternal morbidity and maternal mortality in Thyolo District, Malawi: the impact of obstetric audit.

BACKGROUND Critical incident audit and feedback are recommended interventions to improve the quality of obstetric care. To evaluate the effect of audit at district level in Thyolo, Malawi, we assessed the incidence of facility-based severe maternal complications (severe acute maternal morbidity (SAMM) and maternal mortality) during two years of audit and feedback. METHODOLOGY/PRINCIPAL FINDINGS Between September 2007 and September 2009, we included all cases of maternal mortality and SAMM that occurred in Thyolo District Hospital, the main referral facility in the area, using validated disease-specific criteria. During two- to three-weekly audit sessions, health workers and managers identified substandard care factors. Resulting recommendations were implemented and followed up. Feedback was given during subsequent sessions. A linear regression analysis was performed on facility-based severe maternal complications. During the two-year study period, 386 women were included: 46 died and 340 sustained SAMM, giving a case fatality rate of 11.9%. Forty-five cases out of the 386 inclusions were audited in plenary with hospital staff. There was a reduction of 3.1 women with severe maternal complications per 1000 deliveries in the district health facilities, from 13.5 per 1000 deliveries in the beginning to 10.4 per 1000 deliveries at the end of the study period. The incidence of uterine rupture and major obstetric hemorrhage reduced considerably (from 3.5 to 0.2 and from 5.9 to 2.6 per 1000 facility deliveries respectively). CONCLUSIONS Our findings indicate that audit and feedback have the potential to reduce serious maternal complications including maternal mortality. Complications like major hemorrhage and uterine rupture that require relatively straightforward intrapartum emergency management are easier to reduce than those which require uptake of improved antenatal care (eclampsia) or timely intravenous medication or HIV-treatment (peripartum infections).
