Maternal death and postpartum hemorrhage in sub-Saharan Africa - A pilot study in metropolitan Mozambique

Burden and outcomes of postpartum haemorrhage in Nigerian referral-level hospitals

OBJECTIVE

To determine the prevalence of primary postpartum haemorrhage (PPH), risk factors, and maternal and neonatal outcomes in a multicentre study across Nigeria.

DESIGN

A secondary data analysis using a cross-sectional design.

SETTING

Referral-level hospitals (48 public and six private facilities).

POPULATION

Women admitted for birth between 1 September 2019 and 31 August 2020.

METHODS

Data collected over a 1-year period from the Maternal and Perinatal Database for Quality, Equity and Dignity programme in Nigeria were analysed, stratified by mode of delivery (vaginal or caesarean), using a mixed-effects logistic regression model.

MAIN OUTCOME MEASURES

Prevalence of PPH and maternal and neonatal outcomes.

RESULTS

Of 68 754 women, 2169 (3.2%, 95% CI 3.07%-3.30%) had PPH, with a prevalence of 2.7% (95% CI 2.55%-2.85%) and 4.0% (95% CI 3.75%-4.25%) for vaginal and caesarean deliveries, respectively. Factors associated with PPH following vaginal delivery were: no formal education (aOR 2.2, 95% CI 1.8-2.6, P < 0.001); multiple pregnancy (aOR 2.7, 95% CI 2.1-3.5, P < 0.001); and antepartum haemorrhage (aOR 11.7, 95% CI 9.4-14.7, P < 0.001). Factors associated with PPH in a caesarean delivery were: maternal age of >35 years (aOR 1.7, 95% CI 1.5-2.0, P < 0.001); referral from informal setting (aOR 2.4, 95% CI 1.4-4.0, P = 0.002); and antepartum haemorrhage (aOR 3.7, 95% CI 2.8-4.7, P < 0.001). Maternal mortality occurred in 4.8% (104/2169) of deliveries overall, and in 8.5% (101/1182) of intensive care unit admissions. One-quarter of all infants were stillborn (570/2307), representing 23.9% (429/1796) of neonatal intensive care unit admissions.

CONCLUSIONS

A PPH prevalence of 3.2% can be reduced with improved access to skilled birth attendants.

Postpartum hemorrhage in Sub-Saharan Africa-a prospective study in metropolitan Mozambique

BACKGROUND

Estimates indicate approximately ≈500 to 1000 maternal deaths per 100,000 live births in Sub-Saharan Africa (SSA) (vs ≈5-20 in developed countries). Postpartum hemorrhage (PPH) seems a major contributor to maternal mortality (MM), but there are no comprehensive data for the region.

OBJECTIVES

Analyze MM, PPH, and associated risk factors.

METHODS

We collected prospective data on MM, PPH, and associated risk factors in metropolitan Mozambique. We recorded consecutive deliveries at the Maputo Central Hospital between February 2019 and January 2021. Data included age, HIV status, parity, delivery mode, notes, vital signs, laboratory values, and fetal parameters. PPH was determined by charted diagnosis, blood loss of >500 mL, transfusion, and/or notes indicating significant bleeding.

RESULTS

Of 8799 deliveries, ≈40% occurred in women residing outside Maputo City ("nonlocal"), with similar demographic characteristics between local and nonlocal women. However, compared with local women, nonlocal women had worse outcomes, including higher rates of MM (1.52% vs 0.78%; P =.0012) and PPH (16.51% vs 12.39%; P <.0001), whereby PPH was strongly associated with MM (adjusted odds ratio = 5.56; P <.0001). Almost all women with uterine atony (≈1%) experienced PPH. For women receiving laboratory tests on admission (drawn only if in distress; local, n = 561; nonlocal, n = 514), both cohorts revealed similar distributions of hemoglobin levels and platelet counts. Prepartum anemia (≈57%) and thrombocytopenia (≈21%) were prominent risk factors for PPH; risk increased with increasing severity and was additive in the presence of both.

CONCLUSIONS

PPH is a serious problem in Maputo province, a metropolitan area of SSA, portending high MM. Identification of correctable risk factors, including anemia, should catalyze the development of region-specific prevention protocols.

Utilization of non-pneumatic anti-shock garment for treating obstetric hemorrhage and associated factors among obstetric care providers in Ethiopia: A systematic review and meta-analysis

BACKGROUND

The non-pneumatic anti-shock garment (NASG) is a life-saving device that can help to avoid delays and prevent further complications in the case of obstetric hemorrhage. Although there are many fragmented primary studies on the NASG utilization in Ethiopia, the pooled utilization rate is unknown. In addition, a disagreement was observed among those studies while reporting the associated factors. Therefore, this study was intended to determine the pooled level of NASG utilization and its associated factors among obstetric care providers in Ethiopia.

METHODS

A total of 51 studies were retrieved from PubMed, Google Scholar, the African Journal of Online, direct open-access journals, and Ethiopian universities' institutional repositories. This study was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The quality of studies was evaluated using the modified Newcastle-Ottawa quality assessment tool. The data were extracted by two authors independently using Microsoft Excel and analyzed by Stata version 11. A random-effects model was applied to calculate the pooled level of NASG utilization and its associated factors. The PROSPERO registration number for the review is CRD42023414043.

RESULT

A total of 8 studies comprising 2,575 study participants were involved in this meta-analysis. The pooled utilization rate of NASG was found to be 39.56%. Having NASG training (pooled odds ratio (OR) = 3.99, 95%CI = 2.35, 6.77), good knowledge about NASG (OR = 2.92, 95%CI = 2.04, 4.17), a positive attitude towards NASG (OR = 3.17, 95%CI = 2.10, 4.79), and having ≥ 2 NASGs in the health facility (OR = 10.59, 95%CI = 6.59, 17.01) were significantly associated with NASG utilization.

CONCLUSION

Utilization of NASG for the treatment of obstetric hemorrhage was low in Ethiopia. To increase its utilization, Ministry of Health should improve the accessibility of NASG at each health facility and increase the Health professionals' knowledge and attitude through in-service and pre-service training.

Uterine artery embolization in Tanzania: a procedure with major public health implications

BACKGROUND

The burden of uterine fibroids is substantial in sub-Saharan Africa (SSA), with up to 80% of black women harboring them in their lifetime. While uterine artery embolization (UAE) has emerged as an effective alternative to surgery to manage this condition, the procedure is not available to the vast majority of women living in SSA due to limited access to interventional radiology (IR) in the region. One of the few countries in SSA now offering UAE in a public hospital setting is Tanzania. This study aims to assess the safety and effectiveness of UAE in this new environment.

METHODS

From June 2019 to July 2022, a single-center, retrospective cohort study was conducted at Tanzania's first IR service on all patients who underwent UAE for the management of symptomatic fibroids or adenomyosis. Patients were selected for the procedure based on symptom severity, imaging findings, and medical management failure. Procedural technical success and adverse events were recorded for all UAEs. Self-reported symptom severity and volumetric response on imaging were compared between baseline and six-months post-procedure using paired sample t-tests.

RESULTS

During the study period, 92.1% (n = 35/38) of patients underwent UAE for the management of symptomatic fibroids and 7.9% (n = 3/38) for adenomyosis. All (n = 38/38) were considered technically successful and one minor adverse event occurred (2.7%). Self-reported symptom-severity scores at six-months post-procedure decreased in all categories: abnormal uterine bleeding from 8.8 to 3.1 (-5.7), pain from 6.7 to 3.2 (-3.5), and bulk symptoms from 2.8 to 1 (-1.8) (p < 0.01). 100% of patients reported satisfaction with outcomes. Among the nine patients with follow-up imaging, there was a mean volumetric decrease of 35.5% (p = 0.109).

CONCLUSIONS

UAE for fibroids and adenomyosis can be performed with high technical success and low complication rates in a low-resource setting like Tanzania, resulting in significant symptom relief for patients. Building capacity for UAE has major public health implications not only for fibroids and adenomyosis, but can help address the region's leading cause of maternal mortality, postpartum hemorrhage.

Knowledge of Postbirth Warning Signs and Postpartum Education Among Women in Ghana

OBJECTIVE

To assess the relationship between postpartum education and knowledge of postbirth warning signs among women in Ghana.

DESIGN

Cross-sectional survey.

SETTING

Tamale West Hospital in Tamale Metropolitan Area, Ghana.

PARTICIPANTS

Women (N = 151) who gave birth to healthy newborns and were admitted to the postnatal ward.

METHODS

We collected data from surveys distributed in the hospital. The survey included items for sociodemographic characteristics, obstetric history, postpartum education provided, and knowledge of nine common postbirth warning signs. We used descriptive statistics and multivariate logistic regression models to analyze the data.

RESULTS

Participants reported knowing an average of 5.2 of 9 (SD = 2.84) postbirth warning signs. Severe bleeding (94.70%, n = 143), fever (82.12%, n = 124), and severe headache (72.19%, n = 109) were the postbirth warning signs most frequently identified by participants. Swelling in the leg (37.09%, n = 56) and thoughts of hurting oneself (33.11%, n = 50) were the postbirth warning signs least frequently identified by participants. Knowledge about postbirth warning signs was positively associated with reports of receiving educational handouts on the postnatal ward (adjusted OR = 4.64, 95% confidence interval [1.27, 17.04]) and reports that four or more postpartum complications were taught before hospital discharge (adjusted OR = 27.97, 95% confidence interval [7.55, 103.57]) compared to zero to three postpartum complications.

CONCLUSION

All women need comprehensive discharge education on the warning signs of complications after birth. Promoting knowledge of postbirth warning signs can decrease delays in seeking care and contribute to the reduction of maternal mortality in Ghana.

Prepartum Anemia and Risk of Postpartum Hemorrhage: A Meta-Analysis and Brief Review

Postpartum hemorrhage (PPH) is responsible for 30% to 50% of maternal deaths. There is conflicting evidence if prepartum anemia facilitates PPH. A comprehensive analysis of studies describing their relation is missing. An extensive database search was conducted applying the terms "anemia" OR "hemoglobin" AND "postpartum hemorrhage." We used a random-effects meta-analysis model to estimate an overall odds ratio (OR) for PPH and prepartum anemia, separating studies that were conformant and non-conformant with the World Health Organization (WHO) definitions for anemia. The search yielded 2519 studies, and 46 were appropriate for analysis. The meta-analyses of WHO-conformant (n = 22) and non-conformant (n = 24) studies showed that the risk of PPH was increased when anemia was present. The ORs were 1.45 (CL: 1.23-1.71) for WHO-conformant studies, 2.88 (CL: 1.38-6.02) for studies applying lower thresholds for anemia, and 3.28 (CL: 2.08-5.19) for undefined anemia thresholds. PPH risk appeared to increase with lower anemia thresholds. Prepartum anemia is associated with an increased risk of PPH, an observation that is important regarding improved anemia correction strategies such as iron supplementation.

Obstetric hemorrhage: effective methods for addressing the menace in Sub-Saharan Africa

Obstetric hemorrhage is a serious emergency. It can occur late in pregnancy and in the immediate postpartum period. Postpartum hemorrhage is the major contributor of maternal deaths worldwide. The incidence of PPH-associated death across the African continent is at least three times higher than in other regions of the world. About 17% of PPH result in severe morbidity, including significant organ impairment. Maternal death and disability have long-lasting negative consequences for children, families, and communities. There are considerable variations across regions with for instance PPH accounting for about 8.0% of maternal deaths in developed countries compared to 19.7% in the developing countries. This disparity suggests that the majority of lives lost from PPH are preventable. Instituting primary preventive measures, prenatal care, comprehensive antenatal care, understanding the concept of birth preparedness and complication readiness, skilled birth attendant at delivery, avoiding delays, availability of comprehensive emergency obstetric care (CEmOC), good political will and disseminating the information on maternal mortality from PPH to the community are among key elements necessary to address the menace of PPH in developing countries. The aim of this review is to highlight the contributions of obstetric hemorrhage as a significant cause of maternal morbidity and mortality and suggest measures of prevention.

Critical factors associated with postpartum maternal death in Ethiopia

BACKGROUND

Globally most maternal deaths occur during the postpartum period; however, the burden is disproportionately higher in some Sub-Saharan African countries including Ethiopia. According to Ethiopian Ministry of Health's annual report, in 2019 alone, nearly 70% of maternal deaths happen during the postpartum period. Although several studies have been conducted on postpartum maternal deaths in Ethiopia, most of the studies were focused either on individual-level or district-level determinants with limited emphasis on the timing of death and in relatively small and localized areas. Therefore, this study aimed at identifying the determinants of postpartum death both at an individual and districts level, which could shed light on designing pragmatic policies to reduce postpartum maternal death.

METHODS

The study utilized secondary data obtained from the Ethiopian maternal death surveillance system. A total of 4316 reviewed maternal death from 645 districts of Ethiopia were included in the analysis. A multilevel multinomial logistic regression model was applied to examine factors significantly associated with postpartum maternal death in Ethiopia.

RESULT

The findings revealed that 65.1% of maternal deaths occurred during the postpartum period. The factors associated with postpartum death included previous medical history (history of ANC follow up and party), medical causes (obstetrics haemorrhage, hypertensive disorder of pregnancy, pregnancy-related infection, and non-obstetrics complication), personal factors (poor knowledge of obstetrics complication), and facility-level barriers (shortage of life-saving maternal commodities and delay in receiving treatment).

CONCLUSION

Almost seven in ten maternal deaths happen during the postpartum period. The rate was even higher for some women based on their previous medical history, level of awareness about obstetrics complication, medical conditions, as well as the readiness of the health facility at which the women was served. Since the postpartum period is identified as a critical time for reducing maternal death, policies and actions must be directed towards improving health education, ANC service utilization, and facility-level readiness.

Magnitude of postpartum hemorrhage and its associated factors in Ethiopia: a systematic review and meta-analysis

BACKGROUND

Postpartum hemorrhage or postpartum bleeding (PPH) is often defined as loss of > 500 ml of blood after vaginal delivery or > 1000 ml after cesarean delivery within 24 h. Postpartum hemorrhage is a leading direct cause of maternal morbidity and mortality in Ethiopia. Therefore, the main objective of this systematic review and meta-analysis was to estimate the pooled magnitude of postpartum hemorrhage and the pooled effect size of the associated factors in Ethiopia.

METHODS

Primary studies were searched from PubMed/MEDLINE online, Science Direct, Hinari, Cochrane Library, CINAHL, African Journals Online, Google and Google Scholars databases. The searching of the primary studies included for this systematic review and meta-analysis was limited by papers published from 2010 to October 10/2021. The data extraction format was prepared in Microsoft Excel and extracted data was exported to Stata Version 16.0 statistical software for analysis. A random effect meta-analysis model was used. Statistical heterogeneity was evaluated by the I2 test and Egger's weighted regression test was used to assess publication bias.

RESULT

A total of 21 studies were included in this meta-analysis. The pooled magnitude of postpartum hemorrhage in Ethiopia was 8.24% [(95% CI 7.07, 9.40]. Older age [OR = 5.038 (95% CI 2.774, 9.151)], prolonged labor [OR = 4.054 (95% CI 1.484, 11.074)], absence of anti-natal care visits (ANC) [OR = 13.84 (95% CI 5.57, 34.346)], grand-multiparty [OR = 6.584 (95% CI 1.902, 22.795)], and history of postpartum hemorrhage [OR = 4.355 (95% CI 2.347, 8.079)] were factors associated with the occurrence of postpartum hemorrhage.

CONCLUSIONS

The pooled magnitude of postpartum hemorrhage among post-natal mothers in Ethiopia was moderately high. The finding of this study will strongly help different stakeholder working in maternal and child health to focus on the main contributors' factors to reduce post-partum hemorrhage among postnatal mothers. Health professionals attending labor and delivery should give more attention to advanced aged mothers, grand-multipara mothers and mothers who had a history of post-partum hemorrhage due to higher risk for postpartum hemorrhage. Encouraging to continue ANC visit and prevent prolonged labor should also be recommended to decrease postpartum hemorrhage.

Literature Review: Physiological Management for Preventing Postpartum Hemorrhage

The aim of this paper was to summarize the existing literature regarding postpartum hemorrhage (PPH) and its physiological management (i.e., skin-to-skin contact and breastfeeding). The background surrounding PPH and the role of skin-to-skin contact (SSC) and breastfeeding (BF) in PPH are identified, and these interventions are supported as a crucial means of preventing or minimizing the incidence of PPH. Despite its importance, to the best of my knowledge, an evaluation of this relationship has not yet been undertaken. The narrative literature review approach was used to summarize topic related researches. The search included three databases: CINAHL, PubMed, and Google Scholar. All articles related to the role of SSC and BF in PPH were chosen from the different databases. The findings demonstrate that SSC and BF are cost-effective methods that could be considered practices for the prevention of PPH. Immediate Skin-to-skin contact (SSC) and breastfeeding (BF) are central mediators of the psychophysiological process during the first hour after delivery (the third and fourth stages of labor).
