Improvement in the active management of the third stage of labor for the prevention of postpartum hemorrhage in Tanzania: a cross-sectional study

Impact of quality improvement interventions on facility readiness, quality and uptake of maternal and child health services in developing regions of Ethiopia: a secondary analysis of programme data

BACKGROUND

Quality improvement intervention (QI) was implemented from 2018 to 2021 in health facilities of developing regional states of Ethiopia. The main objective of this study was to examine the impact of QI interventions on facility readiness, service availability, quality and usage of health services in these regions.

METHODS

We used district health information system data of 56 health facilities (HFs). We also used baseline and endline QI monitoring data from 28 HFs. Data were summarised using descriptive statistics and various tests. Regression analysis was employed to examine the impact of QI interventions on various outcomes.

RESULT

The QI intervention improved readiness of HFs, service availability and quality of maternal and child health service delivery. The mean availability of basic amenities increased from 1.89 to 2.89; HF cleanliness score increased from 4.43 to 5.96; family planning method availability increased from 4 to 5.75; score for emergency drugs at labour ward increased from 5.32 to 7.00; and the mean score for basic emergency obstetric and newborn care service availability increased from 5.68 to 6.75; intrauterine contraceptive devices removal service increased from 39.3% to 82.1%; and partograph use increased from 53.6% to 92.9%. HFs that use partograph for labour management increased by 39.3%. The QI intervention increased the quality of antenatal care by 29.3%, correct partograph use by 51.7% and correct active third-stage labour management, a 19.6% improvement from the baseline. The interventions also increased the service uptake of maternal health services, but not significantly associated with improvement in contraceptive service uptake.

CONCLUSION

The integrated QI interventions in HFs could have an impact on facility readiness for service delivery, service accessibility and quality of service delivery. The effectiveness of the QI intervention should be evaluated using robust methods, and efforts to enhance contraceptive services through a QI approach requires further study.

Obstetric and Maternal Outcomes After B-Lynch Compression Sutures: A Meta-Analysis

This review article aimed to determine the obstetric and maternal outcomes after B-Lynch compression sutures to control atonic postpartum hemorrhage (PPH). This meta-analysis was performed after registering the protocol in the PROSPERO database with the registration number CRD42022355358. Two independent reviewers systematically searched electronic databases and search engines (PubMed, Cochrane Library, and Google Scholar) to retrieve published articles from inception to July 2022. The obstetric and maternal outcomes after the B-Lynch compression suture were computed using the random-effects model in pooled proportion with a 95% confidence interval (CI). Meta-regression analysis and subgroup analysis were performed to explain any source of possible heterogeneity. Quality assessment of the included studies was done using Joanna Briggs Institute (JBI) tools which are critical appraisal tools for systematic reviews and meta-analyses. This meta-analysis included a total of 30 studies involving 1,270 subjects. The pooled proportion of B-Lynch suture alone was 91% (95% CI = 82-97%). The combined proportion of B-Lynch suture plus another compression suture was 1% (95% CI = 0-3%), and the pooled proportion of B-Lynch suture plus vessel ligation was 3% (95% CI = 1-6%). The pooled proportions of PPH controlled and hysterectomies were 94% (95% CI = 91-97%, I² = 65.3%) and 7% (95% CI = 4-10%, I² = 72.13%), respectively. Therefore, B-Lynch suture (either alone or in combination with other techniques) is a simple and effective measure to control atonic PPH.

Effects of multifaceted interventions to prevent and manage primary postpartum haemorrhage in referral hospitals: a quasi-experimental study in Nigeria

INTRODUCTION

Primary postpartum haemorrhage (PPH) is the leading cause of Nigeria's high maternal mortality rate. This study investigated the effectiveness of a set of multifaceted interventions to manage and reduce PPH in selected secondary referral health facilities in Nigeria.

METHODS

This is a quasi-experimental study using an interrupted time-series design to assess a set of multifaceted interventions that address factors identified by stakeholders as associated with PPH. Interventions were implemented at two regional general hospitals, with a general hospital in the same region as the control. Intervention participants were women during antepartum and clinical and administrative staff. Cases of PPH were determined in women at delivery. The outcomes measured were the incidence of primary PPH and related deaths during the study period. Analyses included a comparative description of characteristics of the women, trend of time-series data at intervention and control hospitals, and multivariable analysis of factors associated with PPH occurrence.

RESULTS

Monthly numbers of primary PPH were collected at participating hospitals over 21 months for 18 181 women. Intervention hospitals represent 54% vs 46% in control hospitals. Time-series analyses show a significant downward trend in intervention hospitals. The overall incidence of primary PPH was lower in the intervention hospitals than in the control hospitals. Multilevel regression adjusted for hospital-level effect showed a 68% reduction in odds of PPH cases at intervention compared with control hospitals. There were 12 PPH-related maternal deaths in one of the control hospitals, with no deaths in the intervention hospitals.

CONCLUSION

We conclude that multiple interventions that address identified challenges in the prevention of primary PPH can potentially effectively reduce reported primary PPH in Nigerian referral hospitals. This approach is relevant for scaling the development of policies and programmes to prevent primary PPH and maternal mortality in Nigeria.

Risk factors for postpartum haemorrhage in the Northern Province of Rwanda: A case control study

Background

Postpartum haemorrhage (PPH) remains a major global burden contributing to high maternal mortality and morbidity rates. Assessment of PPH risk factors should be undertaken during antenatal, intrapartum and postpartum periods for timely prevention of maternal morbidity and mortality associated with PPH. The aim of this study is to investigate and model risk factors for primary PPH in Rwanda.

Methods

We conducted an observational case-control study of 430 (108 cases: 322 controls) pregnant women with gestational age of 32 weeks and above who gave birth in five selected health facilities of Rwanda between January and June 2020. By visual estimation of blood loss, cases of Primary PPH were women who changed the blood-soaked vaginal pads 2 times or more within the first hour after birth, or women requiring a blood transfusion for excessive bleeding after birth. Controls were randomly selected from all deliveries without primary PPH from the same source population. Poisson regression, a generalized linear model with a log link and a Poisson distribution was used to estimate the risk ratio of factors associated with PPH.

Results

The overall prevalence of primary PPH was 25.2%. Our findings for the following risk factors were: antepartum haemorrhage (RR 3.36, 95% CI 1.80–6.26, P<0.001); multiple pregnancy (RR 1.83; 95% CI 1.11–3.01, P = 0.02) and haemoglobin level <11 gr/dL (RR 1.51, 95% CI 1.00–2.30, P = 0.05). During the intrapartum and immediate postpartum period, the main causes of primary PPH were: uterine atony (RR 6.70, 95% CI 4.78–9.38, P<0.001), retained tissues (RR 4.32, 95% CI 2.87–6.51, P<0.001); and lacerations of genital organs after birth (RR 2.14, 95% CI 1.49–3.09, P<0.001). Coagulopathy was not prevalent in primary PPH.

Conclusion

Based on our findings, uterine atony remains the foremost cause of primary PPH. As well as other established risk factors for PPH, antepartum haemorrhage and intra uterine fetal death should be included as risk factors in the development and validation of prediction models for PPH. Large scale studies are needed to investigate further potential PPH risk factors.

Knowledge and skills on active management of third stage of labor for prevention of post-partum haemorrhage among health care providers in Lake Zone, Tanzania: a cross sectional study

BACKGROUND

Health care providers (HCPs) knowledge and skills are both crucial in saving the lives of mothers and their newborns during childbirth. This study aimed to assess the knowledge and skills of HCPs on active management of third stage of labor (AMTSL) for prevention of PPH in Lake Zone Tanzania.

METHODS

A cross-sectional analytical hospital-based study which included 340 HCPs who were randomly selected, the study was conducted from March to May 2019 in lake zone, Tanzania. Data were collected using standardized questionnaire and observational checklist. Predictors of knowledge and skills on AMTSL were determined using binary logistic regression under multivariable analysis using SPSS version 23.0. p-value less than 0.05 was considered significant.

RESULTS

Most 200 (58.8%) of the participants were aged between 25 and 34 years with mean age 31.4 ± 6.26 years. Majority 240 (67.6%) were females. Of all HCPs, 171 (50.3%) had adequate knowledge whereas 153 (45.0%) had adequate skills on AMTSL. Males (AOR = 1.96, 95% CI 1.18-3.26), HCPs with University education (AOR = 3.29, 95% CI 1.19-9.13) and previous BEmONC training (AOR = 2.20, 95% CI 1.24-3.91) were found to be the predictors of adequate knowledge on AMTSL. HCPs aged ≥ 45 years (AOR = 9.35, 95% CI 1.74-10.28) and HCPs working at a hospital (AOR = 1.78, 95% CI 1.12-2.82) were associated with having adequate skills on AMTSL.

CONCLUSION

HCPs included in this study demonstrated low skills on AMTSL as compared to knowledge which needs immediate attention. We recommend continuous in-service training and supportive supervision among HCPs working in labour wards for improving their knowledge and skills on AMTSL. This will help to reduce maternal morbidity and mortality related to PPH.

Placenta Previa Complicated with Endometriosis: Contemporary Clinical Management, Molecular Mechanisms, and Future Research Opportunities

Endometriosis is a common gynecological disease characterized by chronic inflammation, with an estimated prevalence of approximately 5–15% in reproductive-aged women. This study aimed to assess the relationship between placenta previa (PP) and endometriosis. We performed a systematic review of the literature until 30 June 2021, and 24 studies met the inclusion criteria. Using an adjusted pooled analysis, we found that women with endometriosis had a significantly increased rate of PP (adjusted odds ratio (OR) 3.17, 95% confidence interval (CI) 2.58–3.89) compared to those without endometriosis. In an unadjusted analysis, severe endometriosis was associated with an increased prevalence of PP (OR 11.86, 95% CI 4.32–32.57), whereas non-severe endometriosis was not (OR 2.16, 95% CI 0.95–4.89). Notably, one study showed that PP with endometriosis was associated with increased intraoperative bleeding (1.515 mL versus 870 mL, p < 0.01) compared to those without endometriosis. Unfortunately, no studies assessed the molecular mechanisms underlying PP in patients with endometriosis. Our findings suggest that there is a strong association between endometriosis and a higher incidence of PP, as well as poor surgical outcomes during cesarean delivery. Therefore, the development of novel therapeutic agents or methods is warranted to prevent PP in women with endometriosis.

A systematic review and meta-analysis of obstetric and maternal outcomes after prior uterine artery embolization

This study aimed to review the obstetric complications during subsequent pregnancies after uterine artery embolization (UAE) for postpartum hemorrhage (PPH) by exploring the relationship between prior UAE and obstetric complications through a meta-analysis. We conducted a systematic literature review through March 31, 2021, using PubMed, Scopus, and the Cochrane Central Register of Controlled Trials in compliance with the PRISMA guidelines and determined the effect of prior UAE for PPH on the rate of placenta accreta spectrum (PAS), PPH, placenta previa, hysterectomy, fetal growth restriction (FGR), and preterm birth (PTB). Twenty-three retrospective studies (2003–2021) met the inclusion criteria. They included 483 pregnancies with prior UAE and 320,703 pregnancies without prior UAE. The cumulative results of all women with prior UAE indicated that the rates of obstetric complications PAS, hysterectomy, and PPH were 16.3% (34/208), 6.5% (28/432), and 24.0% (115/480), respectively. According to the patient background-matched analysis based on the presence of prior PPH, women with prior UAE were associated with higher rates of PAS (odds ratio [OR] 20.82; 95% confidence interval [CI] 3.27–132.41) and PPH (OR 5.32, 95% CI 1.40–20.16) but not with higher rates of hysterectomy (OR 8.93, 95% CI 0.43–187.06), placenta previa (OR 2.31, 95% CI 0.35–15.22), FGR (OR 7.22, 95% CI 0.28–188.69), or PTB (OR 3.00, 95% CI 0.74–12.14), compared with those who did not undergo prior UAE. Prior UAE for PPH may be a significant risk factor for PAS and PPH during subsequent pregnancies. Therefore, at the time of delivery, clinicians should be more attentive to PAS and PPH when women have undergone prior UAE. Since the number of women included in the patient background-matched study was limited, further investigations are warranted to confirm the results of this study.

Knowledge and barriers on correct use of modified guidelines for active management of third stage of labour: a cross sectional survey of nurse-midwives at three referral hospitals in Dar es Salaam, Tanzania

Background

Despite the fact that it is possibly preventable, postpartum haemorrhage (PPH) is the global most deadly form of obstetric bleeding, mainly sub-Saharan Africa with at least one-fourth of maternal deaths in East African regions. Active management of third stage of labour (AMTSL) is recommended to prevent PPH. However, AMTSL guidelines have been revised since 2006.

Objectives

To examine the current status of nurse-midwives' knowledge on modified AMTSL guidelines and highlight barriers to AMTSL correct use.

Method

Descriptive cross sectional survey was conducted to 160 nurse-midwives at three referral hospitals in Dar es Salaam, Tanzania. One-way, interactive modes ANOVA and Chi square (χ2) test were run in SPSS 21 version to compare the association of independent and dependent variables.

Results

Virtually all nurse-midwives knew the first recommended uterotonic (99.4%) and delayed cord clamping (98.8%) protocols as modified. Knowledge was significantly contributed by multiple factors; p=0.001. Reported correct AMTSL use was 46.8% which was significantly affected by AMTSL training (χ2 = 6.732, p = 0.009) and prioritizing atteding an asphyxiated baby (χ2 = 5.647, p = 0.017).

Conclusion

Regardless of high nurse-midwives' AMTSL knowledge; it is imperative that responsible authorities plan appropriate strategies to solve reported barriers affecting correct AMTSL use.

Obstetric Outcomes of Pregnancy After Uterine Artery Embolization

BACKGROUND

Uterine artery embolization (UAE) is used to treat severe postpartum hemorrhage (PPH). According to a few studies, UAE for PPH was associated with preterm birth, fetal growth restriction (FGR), and placenta accreta spectrum (PAS) in subsequent pregnancies. These previous studies, however, lacked controls, and to the best of our knowledge, no systematic literature reviews have been conducted thus far. We report the results of our retrospective case-control study of pregnancies after UAE at a single center and include a literature review to evaluate the risk of PAS in pregnancies after UAE.

METHODS

We retrospectively reviewed data from deliveries at our hospital between January 2012 and October 2017. We divided the delivery data into cases with previous UAEs performed for PPH (the post-UAE group) and those without UAEs (the non-UAE group, which included women without previous PPH). We defined PAS as cases in which hysterectomy was performed and pathological examination confirmed the diagnosis. Results are presented as odds ratios (ORs) with 95% confidence intervals (95% CIs).

RESULTS

We used data from 3155 patients in this study, of whom 16 patients had undergone UAE (post-UAE group) and 3139 had not (non-UAE group). We found no differences between the groups in terms of frequency of preterm births (12.5% versus 14.2%, respectively; OR, 0.863; 95% CI, 0.218 to 3.414; P = 0.84) or FGR (6.2% versus 10.0%, respectively; OR, 0.602; 95% CI, 0.104 to 3.584; P = 0.61). However, cases of PAS were significantly more common in the post-UAE group (37.5%) than in the non-UAE group (1.2%; OR, 50.303; 95% CI, 17.38 to 145.592; P < 0.01).

CONCLUSION

Our results suggest that previous UAE is a significant risk factor for PAS.

Rater training for standardised assessment of Objective Structured Clinical Examinations in rural Tanzania

OBJECTIVES

To describe a simulation-based rater training curriculum for Objective Structured Clinical Examinations (OSCEs) for clinician-based training for frontline staff caring for mothers and babies in rural Tanzania.

BACKGROUND

Rater training for OSCE evaluation is widely embraced in high-income countries but not well described in low-income and middle-income countries. Helping Babies Breathe, Essential Care for Every Baby and Bleeding after Birth are standardised training programmes that encourage OSCE evaluations. Studies examining the reliability of assessments are rare.

METHODS

Training of raters occurred over 3 days. Raters scored selected OSCEs role-played using standardised learners and low-fidelity mannikins, assigning proficiency levels a priori. Researchers used Zabar's criteria to critique rater agreement and mitigate measurement error during score review. Descriptive statistics, Fleiss' kappa and field notes were used to describe results.

RESULTS

Six healthcare providers scored 42 training scenarios. There was moderate rater agreement across all OSCEs (κ=0.508). Kappa values increased with Helping Babies Breathe (κ=0.28-0.48) and Essential Care for Every Baby (κ=0.42-0.77) by day 3 of training, but not with Bleeding after Birth (κ=0.58-0.33). Raters identified average proficiency 50% of the time.

CONCLUSION

Our study shows that the in-country raters in this study had a hard time identifying average performance despite moderate rater agreement. Rater training is critical to ensure that the potential of training programmes translates to improved outcomes for mothers and babies; more research into the concepts and training for discernment of competence in this setting is necessary.

Men's roles in care seeking for maternal and newborn health: a qualitative study applying the three delays model to male involvement in Morogoro Region, Tanzania

Background

Increasing the utilization of facility-based care for women and newborns in low-resource settings can reduce maternal and newborn morbidity and mortality. Men influence whether women and newborns receive care because they often control financial resources and household decisions. This influence can have negative effects if men misjudge or ignore danger signs or are unwilling or unable to pay for care. Men can also positively affect their families’ health by helping plan for delivery, supplementing women’s knowledge about danger signs, and supporting the use of facility-based care. Because of these positive implications, researchers have called for increased male involvement in maternal and newborn health. However, data gathered directly from men to inform programs are lacking.

Methods

This study draws on in-depth interviews with 27 men in Morogoro Region, Tanzania whose partners delivered in the previous 14 months. Debriefings took place throughout data collection. Interview transcripts were analyzed inductively to identify relevant themes and devise an analysis questionnaire, subsequently applied deductively to all transcripts.

Results

Study findings add a partner-focused dimension to the three delays model of maternal care seeking. Men in the study often, though not universally, described facilitating access to care for women and newborns at each point along this care-seeking continuum (deciding to seek care, reaching a facility, and receiving care). Specifically, men reported taking ownership of their role as decision makers and described themselves as supportive of facility-based care. Men described arranging transport and accompanying their partners to facilities, especially for non-routine care. Men also discussed purchasing supplies and medications, acting as patient advocates, and registering complaints about health services. In addition, men described barriers to their involvement including a lack of knowledge, the need to focus on income-generating activities, the cost of care, and policies limiting male involvement at facilities.

Conclusion

Men can leverage their influence over household resources and decision making to facilitate care seeking and navigate challenges accessing care for women and newborns. Examining these findings from men and understanding the barriers they face can help inform interventions that encourage men to be positively and proactively involved in maternal and newborn health.

Patterns and causes of hospital maternal mortality in Tanzania: A 10-year retrospective analysis

BACKGROUND

Maternal mortality is among the most important public health concerns in Sub-Saharan Africa. There is limited data on hospital-based maternal mortality in Tanzania. The objective of this study was to determine the causes and maternal mortality trends in public hospitals of Tanzania from 2006-2015.

METHODS AND FINDINGS

This retrospective study was conducted between July and December 2016 and involved 34 public hospitals in Tanzania. Information on causes of deaths due to pregnancy and delivery complications among women of child-bearing age (15-49 years old) recorded for the period of 2006-2015 was extracted. Data sources included inpatient and death registers and International Classification of Disease (ICD)-10 report forms. Maternal deaths were classified based on case definition by ICD 10 and categorized as direct and indirect causes. A total of 40,052 deaths of women of child-bearing age were recorded. There were 1,987 maternal deaths representing 5·0% of deaths of all women aged 15-49 years. The median age-at-death was 27 years (interquartile range: 22, 33). The average age-at-death increased from 25 years in 2006 to 29 years in 2015. Two thirds (67.1%) of the deaths affected women aged 20-34 years old. The number of deaths associated with teenage pregnancy (15-19 years) declined significantly (p-value<0·001) from 17.8% in 2006-2010 to 11.1% in 2011-2015. The proportion of deaths among 30-34 and 35-39 years old (all together) increased from 13% in 2006-2010 to 15·3% in 2011-2015 (p-value = 0.081). Hospital-based maternal mortality ratio increased from 40.24 (2006) to 57.94/100000 births in 2015. Of the 1,987 deaths, 83.8% were due to direct causes and 16.2% were due to indirect causes. Major direct causes were eclampsia (34.0%), obstetric haemorrhage (24.6%) and maternal sepsis (16.7%). Anaemia (14.9%) and cardiovascular disorders (14.0%) were the main indirect causes. Causes of maternal deaths were highly related; being attributed to up to three direct causes (0.12%). Cardiovascular disorders and anaemia had strong linkage with haemorrhage. While there was a decline in the number of deaths due to eclampsia and abortion, those due to haemorrhage and cardiovascular disoders increased during the period.

CONCLUSIONS

During the ten year period (2006-2015) there was an increase in the number of hospital maternal deaths in public hospitals in Tanzania. Maternal deaths accounted for 5% of all women of child-bearing age in-hospital mortalities. Most maternal deaths were due to direct causes including eclampsia, haemorrhage and sepsis. The findings of this study provide evidence for better planning and policy formulation for reproductive health programmes to reduce maternal deaths in Tanzania.
