Maternal health in Namibia: Lessons learned from obstetric surveillance

Over the past decades increasing efforts have aimed to improve the health of pregnant women around the world. Namibia has made limited progress in reducing severe maternal outcomes. Aims of this thesis were to enhance implementation of a national obstetric surveillance system and assess requirements to improve maternal health in Namibia. The findings of chapters 2-7 provided insight into several important drivers of severe maternal outcome. The most important contributor of the high-incidence of severe maternal outcome in Namibia was poor quality of facility-based care and particularly vulnerable women appeared to be at higher risk of severe maternal outcome. Obstetric surveillance played a crucial role in obtaining these insights. Based on these, targeted recommendations could be formulated. The maternity care system needs to be strengthened, to enable health workers to provide universal coverage of good health care to all women in Namibia. It is therefore crucial the next step will follow, which is to act on the proposed recommendations. The insights obtained through obstetric surveillance will contribute to such action, as for any intervention, it is key it addresses a local need in a context-specific manner.

Cardiac and obstetric outcomes of pregnancies for women after cardiotoxic therapy in childhood: a single center observational study

Background: Childhood cancer survivors (CCS) are at increased risk of cardiomyopathy during pregnancy if they have prior cardiotoxic exposure. Currently, there is no consensus on the necessity, timing and modality of cardiac monitoring during and after pregnancy. Therefore, we examined cardiac function using contemporary echocardiographic parameters during pregnancy in CCS with cardiotoxic treatment exposure, and we observed obstetric outcomes in CCS, including in women without previous cardiotoxic treatment exposure. Method: A single-center retrospective cohort study was conducted among 39 women enrolled in our institution's cancer survivorship outpatient clinic. Information on potential cardiotoxic exposure in childhood, cancer diagnosis and outcomes of all pregnancies were collected through interviews and review of health records. Echocardiographic exams before and during pregnancy were retrospectively analyzed for left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) if available. The primary outcomes were (i) left ventricular dysfunction (LVD) during pregnancy, defined as LVEF = 10% in LVEF below normal (Metabolic health: pathophysiological trajectories and therap

Maternal mortality due to cardiac disease in low- and middle-income countries

Objectives To assess the frequency of maternal death (MD) due to cardiac disease in low- and middle-income countries (LMIC).Methods Systematic review searching Medline, EMBASE, Web of Science, Cochrane Library, Emcare, LILACS, African Index Medicus, IMEMR, IndMED, WPRIM, IMSEAR up to 01/Nov/2017. Maternal mortality reports from LMIC reviewing all MD in a given geographical area were included. Hospital-based reports or those solely based on verbal autopsies were excluded. Numbers of MD and cardiac-related deaths were extracted. We calculated cardiac disease MMR (cMMR, cardiac-related MD/100 000 live births) and proportion of cardiac-related MDs among all MDs. Frequency of cardiac MD was compared with the MMR of the country.Results Forty-seven reports were included, which reported on 38,486 maternal deaths in LMIC. Reported cMMR ranged from 0/100 000 live births (Moldova, Ghana) to 31.9/100 000 (Zimbabwe). The proportion of cardiac-related MD ranged from 0% (Moldova, Ghana) to 24.8% (Sri Lanka). In countries with a higher MMR, cMMR was also higher. However, the proportion of cardiac-related MD was higher in countries with a lower MMR.Conclusions The burden of cardiac-related mortality is difficult to assess due limited availability of mortality reports. The proportion of cardiac deaths among all MD appeared to be higher in countries with a lower MMR. This is in line with what has been called 'obstetric transition': pre-existing medical diseases including cardiac disease are becoming relatively more important where the MMR falls

Repeat HIV testing during pregnancy and delivery: missed opportunities in a rural district hospital in Zambia

Objective: To assess coverage of repeat HIV testing among women who delivered in a Zambian hospital. HIV testing of pregnant women and repeat testing every 3 months during pregnancy and breastfeeding is the recommended policy in areas of high HIV prevalence. Methods: A prospective implementation study in a second-level hospital in rural Zambia. Included were all pregnant women who delivered in hospital during May and June 2012. Data regarding antenatal visits and HIV testing were collected by two investigators using a standardised form. Results: Of 401 women who delivered in hospital, sufficient antenatal data could be retrieved for 322 (80.3%) women. Of these 322 women, 301 (93.5%) had attended antenatal care (ANC) at least once. At the time of discharge after delivery in hospital, 171 (53.1%) had an unclear HIV status because their negative test result was more than 3 months ago or of an unknown date, or because they had not been tested at all during pregnancy or delivery. An updated HIV status was present for 151 (46.9%) women: 25 (7.8%) were HIV positive and 126 (39.1%) had tested negative within the last 3 months. In this last group, 79 (24.5%) had been tested twice or more during pregnancy. During the study period, none of the women was tested during admission for delivery. Conclusion: Despite high ANC coverage, opportunities for repeat HIV testing were missed in almost half of all women who delivered in this hospital in a high-prevalence HIV setting

Criteria-based audit of caesarean section in a referral hospital in rural Tanzania

OBJECTIVE: WHO uses the Caesarean section (CS) rate to monitor implementation of emergency obstetric care (EmOC). Although CS rates are rising in sub-Saharan Africa, maternal outcome has not improved. We audited indications for CS and related complications among women with severe maternal morbidity and mortality in a referral hospital in rural Tanzania. METHODS: Cross-sectional study was from November 2009 to November 2011. Women with severe maternal morbidity and mortality were identified and those with CS were included in this audit. Audit criteria were developed based on the literature review and (inter)national guidelines. Tanzanian and Dutch doctors reviewed hospital notes. The main outcome measured was prevalence of substandard quality of care leading to unnecessary CS and delay in performing interventions to prevent CS. RESULTS: A total of 216 maternal near misses and 32 pregnancy-related deaths were identified, of which 82 (33.1%) had a CS. Indication for CS was in accordance with audit criteria for 36 of 82 (44.0%) cases without delay. In 20 of 82 (24.4%) cases, the indication was correct; however, there was significant delay in providing standard obstetric care. In 16 of 82 (19.5%) cases, the indication for CS was not in accordance with audit criteria. During office hours, CS was more often correctly indicated than outside office hours (60.0% vs. 36.0%, P < 0.05). DISCUSSION: Caesarean section rate is not an useful indicator to monitor quality of EmOC as a high rate of unnecessary and potentially preventable CS was identified in this audit

Maternal and fetal outcomes of pregnancies complicated by acute hepatitis E and the impact of HIV status: a cross-sectional study in Namibia

Background & Aims Namibia has been suffering from an outbreak of hepatitis E genotype 2 since 2017. As nearly half of hepatitis E-related deaths were among pregnant and postpartum women, we analysed maternal and fetal outcomes of pregnancies complicated by acute hepatitis E and assessed whether HIV-status impacted on outcome. Methods A retrospective cross-sectional study was performed at Windhoek Hospital Complex. Pregnant and postpartum women, admitted between 13 October 2017 and 31 May 2019 with reactive IgM for Hepatitis E, were included. Outcomes were acute liver failure (ALF), maternal death, miscarriage, intra-uterine fetal death and neonatal death. Odds ratios (OR) and 95% confidence interval (CI) were calculated. Results Seventy women were included. ALF occurred in 28 (40.0%) of whom 13 died amounting to a case fatality rate of 18.6%. Sixteen women (22.9%) were HIV infected, compared to 16.8% among the general pregnant population (OR 1.47, 95% CI 0.84-2.57, P = .17). ALF occurred in 4/5 (80%) HIV infected women not adherent to antiretroviral therapy compared to 1/8 (12.5%) women adherent to antiretroviral therapy (OR 28.0, 95% CI 1.4-580.6). There were 10 miscarriages (14.3%), five intra-uterine fetal deaths (7.1%) and four neonatal deaths (5.7%). Conclusions One in five pregnant women with Hepatitis E genotype 2 died, which is comparable to genotype 1 outbreaks. Despite small numbers, HIV infected women receiving antiretroviral therapy appear to be less likely to develop ALF in contrast with HIV infected women not on treatment. As there is currently no curative treatment, this phenomenon needs to be assessed in larger cohorts
