Child mortality in Bangladesh - why, when, where and how? A national survey-based analysis

From parental education to under-5 mortality: how antenatal care and hand hygiene mediate the pathway mechanisms

BACKGROUND

Reducing the under-5 mortality rate (U5MR) to as low as 25/1000 live births globally by 2030 to reach the sustainable development goal (SDG) 3.2.1 appears to be a race against time. Amidst this situation, Bangladesh experienced stagnancy in U5MR at the beginning of the SDG era. While a comprehensive understanding of this stagnancy is crucial, research on stagnancy is scant and limited to investigating the direct effects of the key predictors. Therefore, building on the existing evidence, this research investigated the effect of one of the key predictors, parental education, on under-5 mortality (U5M) mediated through antenatal care (ANC) and the availability of hand washing stations.

METHODS

This study conducted weighted mediation analyses using the Bangladesh Demographic and Health Survey data from 2011, 2014 and 2017-18, with sample sizes 4,658, 4,367, and 4,826, respectively, and estimated a generalised structural equation model. The "nlcom" post-estimation command of STATA was used to obtain the direct effects (coefficients), which were then multiplied to estimate the indirect effects for the indirect parallel and sequential pathways. The indirect effects were added to obtain the total indirect effect, which was added to the direct effect of education to estimate the total effect of education.

RESULTS

This study reveals inconsistent parallel and sequential mediation of parental education's effect across the three surveys. The direct effect of education on U5M reduced over time. The total (parallel and sequential combined) mediated effects of either parent's education on U5M were negative (reduced U5M risk). While the mediated effect of mother's education on U5M was not significant, the mediated effect of father's education was significant in 2011. The total effect of education (direct and indirect combined) on U5M was negative (reduced U5M risk) and significant in 2011. However, the effect reduced over time and changed direction in 2017-18. Since 2011, the effects decreased and changed direction to become positive (increased U5M risk) in 2017-18. Due to the weakening direct effect of education and the opposite nature of the indirect effect, the indirect effect of education appeared to be greater than the total effect in 2014 and 2017-18. In 2011, approximately 50% of the total effect of either parent's education was mediated. However, in 2014 and 2017-18, the proportions were greater than 100%, except for the proportion of the mediated effect of father's education in 2014.

CONCLUSIONS

This study reports a weakening and inconsistent mediated effect of both parents' education on U5M. Using existing literature, it also justifies that improving the quality of education and ANC could more effectively reduce U5M to achieve SDG 3.2.1. To improve the quality of education, this study recommends updating the school curriculum with a greater emphasis on maternal and child health education. To improve the quality of ANC, it is recommended that the mandatory use of ANC cards be strictly monitored.

Determinants of care-seeking for ARI/Pneumonia-like symptoms among under-2 children in urban slums in and around Dhaka City, Bangladesh

Childhood pneumonia affects an estimated 18% of under-five children in Bangladesh. Urban slum-dwellers face challenges in healthcare-seeking. This study examined the factors influencing the healthcare-seeking for childhood pneumonia among under-two children in urban slums in Bangladesh. The study examined influence of children's characteristics (age, sex, number of ARI/pneumonia symptoms, and duration of symptoms), maternal factors (age, education, and working status), and household characteristics (number of household members, wealth quintile, sex of household heads, age of household heads). The outcome variable was receiving care from a qualified medical provider for childhood pneumonia or pneumonia-like symptoms within 14 days before the collection of surveillance data. The research utilized data from the Urban Health and Demographic Surveillance System, which included 155,000 people from five slums in Dhaka and Gazipur City Corporation areas. Overall, 753 out of 4,679 (16%) children under two years of age were included in this study, all of whom had ARI/pneumonia-like symptoms. The mean age of these children was 11.4 months, and 50% were boys. Of them, 350 (46%) sought care from local pharmacies, while 37% sought care from medically trained providers. Logistic regression analyses indicated that children with multiple symptoms (AOR: 2.32, 95% CI: 1.71-3.14) and illness duration over seven days (AOR: 2.61, 95% CI: 1.51-4.51) had higher odds of receiving care from a medically trained provider. Higher maternal education compared to no formal education, having five or more household members compared to four or fewer, household heads aged 40-49 years compared to those under 25 years, a longer duration of living in the slum (more than 10 years compared to less than five years), and belonging to the richest wealth quintile compared to the poorest were protective factors for care-seeking from qualified providers. Further research is required to understand the context for designing appropriate interventions and comprehensive policies for improved child health regarding ARI/pneumonia-like symptoms.

Pulmonary Function Testing in Healthy Infants in Rural Bangladesh: Feasibility Study

BACKGROUND

Infant pulmonary function testing (iPFT) in low- and middle-income countries is limited. We evaluated the early feasibility of iPFT in rural Bangladesh.

METHODS

Experts established an iPFT laboratory at Zakiganj Upazila Health Complex in Sylhet, Bangladesh and trained staff. Infants ≤ 6 months old participating in a cohort study between 2021 and 2022 were eligible for respiratory oscillometry (Osc), tidal breath flow-volume loops (TBFVL), and sulphur hexaflouride multiple breath washout (MBW) during natural sleep. Participants with a respiratory infection within 4 weeks were not tested. Among the first 25 infants with attempted Osc, TBFVL, or MBW measurements, we report the test proportions meeting international quality standards, measurement averages, and the mean measurement differences between laboratory staff and experts.

RESULTS

Among the first 25 eligible infants with attempted measurements, acceptable Osc measurements were achieved in 88% (22/25), TBFVL in 96% (24/25), and MBW in 88% (22/25). Infants tested by Osc at 2 months were a median (IQR) of 81 days old (73, 85) and tested at 6 months were a median of 194 days old (193, 202); TBFVL/MBW tested infants were a mean 83 days (79, 87). Mean (SD) Osc resistance at 7 Hz was 66.3 (25.2) and 64.0 (22.4) hPa.s.L-1 at 2 and 6 months. At 2 months, TBFVL mean tidal volume/body weight was 7.4 (1.4) mL/kg and MBW mean (SD) lung clearance index was 7.2 (1.0) turnovers. iPFT staff and expert interpretation differences were minimal.

CONCLUSIONS

Establishing an iPFT laboratory and performing quality measurements and expert-level interpretations in rural Bangladesh is feasible.

Factors associated with essential newborn care practices among non-institutional births in urban Bangladesh: evidence from Bangladesh Urban Health Survey 2021

BACKGROUND

Non-institutional births remain prevalent in low- and middle-income countries, associated with a majority of adverse maternal and child health outcomes, including maternal and child mortality. Ensuring essential newborn care (ENC) practices for these non-institutional births is crucial for reducing these adverse outcomes. This study aimed to identify the prevalence, and factors associated with the adoption of ENC practices among non-institutional births in urban Bangladesh.

METHODS

A total of 2,165 children's data were analyzed, extracted from the 35,186 ever-married women interviewed in the 2021 Bangladesh Urban Health Survey. Six ENC components and their level (lowest/none, moderate, and highest) were considered as the outcome variables. Several socio-demographic factors were considered as the explanatory variables. Multivariate binary and multinomial logistic regression model were used to explore the association between outcome and explanatory variables.

RESULTS

Approximately 49% of all mothers reported practicing the highest level of ENC. Among the individual components, the highest adherence was observed for the use of a disinfected instrument to cut the umbilical cord (90%). The likelihood of adopting the highest level of ENC practices was higher among mothers with relatively higher education and wealth quintiles and lower among those residing in slum and other urban areas of city corporations compared to non-slum areas. Mothers living in the Khulna and Sylhet divisions had a lower likelihood of adopting the highest level of ENC practices.

CONCLUSION

Awareness building programs are needed to educate the population, particularly mothers, about the importance of practicing ENC for improving maternal and child health outcomes.

Delayed cord clamping: Perceptions, practices and influencers among the healthcare providers of selected healthcare facilities in Bangladesh

BACKGROUND

Umbilical cord clamping is a procedure of separating the newborn after birth with varying recommendations worldwide based on the timing of clamping. Although the benefits of delayed cord clamping (DCC) have been acknowledged, there is a lack of understanding regarding healthcare providers' perceptions and practices, particularly in Bangladesh. This study aimed to explore the perceptions, practices, and influencers of DCC among healthcare providers in selected secondary-level healthcare facilities in Bangladesh.

METHODS

This qualitative study was conducted at two public healthcare facilities. Purposive sampling was used to select 30 participants for in-depth and key-informant interviews and non-participatory observations for 13 deliveries were done. A thematic analysis approach was employed to identify emerging themes, and interpretive phenomenological analysis of the observations helped verify and contextualise the reported practices. Statistical software N-Vivo (Version-12, Denver) was used for data analysis.

RESULTS

Healthcare providers perceived that cord clamping should occur after one to three minutes, primarily informed by international literature, maternal health training, or peer guidance. Providers recognised DCC's benefits, such as enhanced bonding and reduced neonatal blood transfusions, and noted potential risks of early cord clamping like delayed adaptation and hypoxia. Observation of clamping practices revealed that most providers clamped after pulsation stopped or within three minutes, while caesarean sections often required immediate clamping. Variations existed in the number and type of clamps, with an absence of standardised guidelines. Influencing factors include the cultural impact of Traditional Birth Attendants (Dais), lack of formal training, clinical emergencies, and service delivery challenges such as high patient volumes and staff shortages. Peer learning was a major influencer of practices.

CONCLUSION

Despite having a perception regarding DCC, gaps were identified in the practice of healthcare providers. Addressing this gap and the identified influencers will require the involvement of healthcare workers, guidance developers and planners across policy and practice.

'Counselling is the only thing to do': healthcare providers' experience of Kangaroo Mother Care in Bangladesh - a qualitative study

Aim

To explore healthcare providers' (HCPs) experiences of facility-initiated kangaroo mother care (KMC) in Bangladesh.

Methods

An explorative qualitative study based on 11 semistructured interviews with HCPs from 2 hospitals in Dhaka was conducted. Nurses, medical officers and paediatric consultants were representing the HCPs. Inductive, qualitative content analysis was used.

Results

Supporting KMC needs to be a continuous process that requires a high level of commitment from healthcare staff. Optimal implementation is, however, challenged by structural conditions such as shortage of staff, separation of mother and child, and incomplete follow-up, which need to be addressed to support KMC.

Conclusion

Findings from this formative research can help in designing interventions for scaling up KMC in Bangladesh by paying attention to the crucial role of HCPs and giving them training on the importance of continuous and repeated counselling to both mother and family. To enhance motivation, involving nurses in follow-up care is essential, alongside strengthening the health system for families living far away and tracking those not attending follow-up. Furthermore, after this study was conducted, the WHO updated its recommendations regarding KMC. This means that the current study, in combination with the WHO's new recommendations, can be used for the development of new guidelines for KMC in clinical practice in Bangladesh.

Dysregulated blood biomarkers in women with acute and chronic respiratory conditions due to air pollutant exposure: An exploratory systematic review

Background

Air pollution exposure poses significant health risks for the general population, but particularly for women with acute and chronic respiratory conditions. Given the increasing global burden of air pollution-related illnesses, understanding these biomarkers is crucial for developing targeted interventions and improving respiratory health outcomes in vulnerable populations. In this systematic review, we aimed to determine potential dysregulated respiratory inflammatory blood biomarker candidates in adult female patients who experience varying levels and sources of inhaled pollutant exposure.

Methods

We searched the Cochrane Library, PubMed, and Web of Science with nuanced search terms to retrieve articles published in English between 1 January 2000 and 12 June 2023, to ensure relevancy. We filtered our findings to generate a focussed narrative analysis and used the Risk of Bias In Non-randomized Studies-of Exposures (ROBINS-E) and Risk-of-bias VISualization (robVIS) tools to ensure the validity of the data and the quality of the conclusions being made.

Results

We identified 916 articles from the databases used in our search, 16 of which met the criteria of our focussed narrative analysis. Among blood biomarkers, platelet-activating factor and eosinophilia could be used to assess the severity of asthma conditions, as a lack or reduction thereof indicates specific conditions. Pro-inflammatory cytokines require further validation, as some studies with a high risk of bias have reported conflicting results compared to more recent research on whether these markers are up-regulated or down-regulated. We found one study to be at a very high risk of bias, two had a high risk of bias, one had some concerns of confounding factors which may not have affected their results, and 12 studies had a low risk of bias.

Conclusions

There were narrowed-down blood biomarker candidates that could be used in future research and avenues of research like generating specific microRNA sequences to test for prognostic/diagnostic tests.

On the interpretability of the SVM model for predicting infant mortality in Bangladesh

BACKGROUND

Although machine learning (ML) models are well-liked for their outperformance in prediction, greatly avoided due to the lack of intuition and explanation of their predictions. Interpretable ML is, therefore, an emerging research field that combines the performance and interpretability of ML models to create comprehensive solutions for complex decision-making analysis. Conversely, infant mortality is a global public health concern affecting health, social well-being, socio-economic development, and healthcare services. The study employs advanced interpretable ML techniques to anticipate and understand the factors affecting infant mortality in Bangladesh, overcoming the shortcomings of the conventional logistic regression (LR) model.

METHODS

By utilizing the global surrogate model and local individual conditional expectation (ICE) interpretability technique, the interpretable support vector machine (SVM) has been used in this study to reveal significant characteristics of infant mortality using data from the Bangladesh Demographic and Health Survey (BDHS) 2017-18. To investigate intricate decision-making analysis of infant mortality, we adapted SVM and LR techniques with the hyperparameter tuning parameters. These models' performances were initially assessed using the receiver operating characteristics (ROC) curve, run-time, and confusion matrix parameters with 100 permutations. Afterward, the SVM model's model-agnostic explanation and the LR model's interpretation were compared to enhance advanced comprehension for further insights.

RESULTS

The results of the 100 permutations demonstrated that the LR model (Average: accuracy = 0.9105, precision = NaN, sensitivity = 0, specificity = 1, F1-score = 0, area under the ROC curve (AUC) = 0.6780, run-time = 0.0832) outperformed the SVM model (Average: accuracy = 0.8470, precision = 0.1062, sensitivity = 0.0949, specificity = 0.9209, F1-score = 0.1000, AUC = 0.5632, run-time = 0.0254) in predicting infant mortality, but the LR model had a slower run-time and it was unable to predict any positive cases. The interpretation of LR analysis revealed that infant mortality rates decrease when mothers give birth after over two years, with higher educational attainment, overweight or obese mothers, working mothers, and families with polluted cooking fuel having lower rates. The local ICE interpretability technique, which depicts individual influences on the average likelihood of dying within the first birthday, explores the interpretable SVM model that mothers with normal BMIs, giving birth within two years, using less polluted cooking fuel, working mothers, and having male infant were more likely to experience infant death. The interpretable SVM model based on the global surrogate model also reveals that working mothers who used polluted cooking fuel at home and working women who used less polluted cooking fuel but had a longer period between pregnancies than two years would have higher infant death rates. Even among non-working mothers who used polluted cooking fuel and gave birth within two years of the preceding one, infant death rates were higher.

CONCLUSIONS

The interpretable SVM model reveals global interpretations help clinicians understand the entire conditional distribution, while local interpretations focus on specific instances, providing different insights into model behavior. Interpretable ML models aid policymakers, stakeholders, and families in understanding and preventing infant deaths by improving policy-making strategies and establishing effective family counseling services.

An analysis of cause-specific under-5 mortality in Bangladesh using the demographic and health survey 2011 and 2017-2018

BACKGROUND

As the Sustainable Development Goal 3.2.1 deadline (2030) approaches, rapidly reducing under-5 mortality (U5M) gains more prominence. However, initiatives or interventions that aided Bangladesh in achieving Millennium Development Goal 4 showed varied effectiveness in reducing certain cause-specific U5M. Therefore, this study aimed to examine the predictors of the key cause-specific mortalities.

METHODS

This cross-sectional study was conducted using the Bangladesh Demographic and Health Survey 2011 and 2017-18 data. Cause-specific U5M was examined using multilevel multinomial mixed-effects analyses, and overall/all-cause U5M was examined using multilevel mixed-effects analyses. The respective estimates were compared.

RESULTS

The cause-specific analysis revealed that pneumonia and prematurity-related U5M were significantly associated with antenatal care and postnatal care, respectively. However, analysis of overall/all-cause U5M did not reveal any significant association with health services. Twins or multiples had a greater risk of mortality from preterm-related conditions (adjusted Relative Risk Ratio (aRRR): 38.01, 95% CI: 19.08-75.7, p < .001), birth asphyxia (aRRR: 6.52, 95% CI: 2.51-16.91, p < .001), and possible serious infections (aRRR: 11.12, 95% CI: 4.52-27.36, p < .001) than singletons. Children born to mothers 18 years or younger also exhibited a greater risk of mortality from these three causes than children born to older mothers. This study also revealed an increase in the predicted risk of prematurity-related mortality in the 2017-18 survey among children born to mothers 18 years or younger, children born to mothers without any formal education, twins or multiples and children who did not receive postnatal care.

CONCLUSIONS

This research provides valuable insights into accelerating U5M reduction; a higher risk of preterm-related death among twins underscores the importance of careful monitoring of mothers pregnant with twins or multiples through the continuum of care; elevated risk of death among children who did not receive postnatal care, or whose mothers did not receive antenatal care stresses the need to strengthen the coverage and quality of maternal and neonatal health care; furthermore, higher risks of preterm-related deaths among the children of mothers with low formal education or children born to mothers 18 years or younger highlight the importance of more comprehensive initiatives to promote maternal education and prevent adolescent pregnancy.

Application of a count regression model to identify the risk factors of under-five child morbidity in Bangladesh

BACKGROUND

Bangladesh has seen a significant decline in child mortality in recent decades, but morbidity among children <5 y of age remains high. The aim of this analysis was to examine trends and identify risk factors related to child morbidity in Bangladesh.

METHODS

This analysis is based on data from four successive cross-sectional Bangladesh Demographic and Health Surveys for the years 2007, 2011, 2014 and 2017-18. Several count regression models were fitted and the best model was used to identify risk factors associated with morbidity in children <5 y of age.

RESULTS

According to the results of the trend analysis, the prevalence of non-symptomatic children increased and the prevalence of fever, diarrhoea and acute respiratory infections (ARIs) decreased over the years. The Vuong's non-nested test indicated that Poisson regression could be used as the best model. From the results of the Poisson regression model, child age, sex, underweight, wasted, stunting, maternal education, wealth status, religion and region were the important determinants associated with the risk of child morbidity. The risk was considerably higher among women with a primary education compared with women with a secondary or greater education in Bangladesh.

CONCLUSIONS

This analysis concluded that child morbidity is still a major public health problem for Bangladesh. Thus it is important to take the necessary measures to reduce child morbidity (particularly fever, diarrhoea and ARI) by improving significant influencing factors.

An explanation of the stagnant under-5 mortality rate in Bangladesh using multilevel, multivariable analysis of three Demographic and Health Surveys

Despite remarkable success in the Millennium Development Goal era, Bangladesh experienced a sluggish reduction in the under-5 mortality rate (U5MR) between 2014 and 2017-18. Our study aimed to explain this stagnancy by examining the variation in the key predictor-specific mortality risks over time, using the Bangladesh Demographic and Health Survey 2011, 2014 and 2017-18 data. We applied multilevel mixed effects logistic regression to examine the extent to which the under-5 mortality (U5M) risks were associated with the key sociodemographic and health service-specific predictors. We found that the rise in mortality risks attributable to maternal age 18 years or below, low maternal education, mother's overweight or obesity and the absence of a handwashing station within the household were the key contributors to the stagnant U5MR between 2014 and 2017-18. Poverty and low education aggravated the mortality risks. Besides, antenatal care (ANC) and postnatal care (PNC) did not impact U5M risks as significantly as expected. Compulsory use of ANC and PNC cards and strict monitoring of their use may improve the quality of these health services. Leveraging committees like the Upazila Hospital Management Committee can bring harmony to implementing policies and programmes in the sectors related to U5M.

Stakeholder engagement to introduce a standardised register for improved inpatient care of newborns and sick children in Bangladesh

Background

Despite a global decrease of 59% in under-five mortality rates from 1990 to 2021, child survival remains a pressing issue. This holds true for Bangladesh, as well. In response, the Government of Bangladesh introduced a standardised register for strengthening the inpatient management of newborns and sick children in 2021.

Methods

We employed a comprehensive four-phase stakeholder engagement process to implement an inpatient register for newborns and sick children. The first stage included identifying and prioritising potential stakeholders at the national and district levels. We identified eight organisations involved in newborn and child health and selected 24 participants from various other sectors for workshops aimed at raising awareness about the register's introduction. These stakeholders also participated in the register's design, development strategies planning, and implementation phases. These phases were led by the 'National Newborn Health and IMCI programme' with support from various partners. A technical working group reviewed existing registers and helped prepare training materials. Feedback from each workshop was crucial in finalising the register.

Results

The Government of Bangladesh has recognised the need for an indoor register for newborns and sick children, which was to be established in collaboration with development partners. This initiative can enhance the quality of care for sick children and increase service provider accountability. Due to its successful implementation, it will continue to be used in the Kushtia and Dinajpur districts, with plans for a nationwide scale-up. The Government has allocated funds in the next health sector programme for orientation and register printing. A strengths, weaknesses, opportunities, and threats (SWOT) analysis of the stakeholder engagement process highlighted strengths such as a context-specific approach and collaborative engagement, as well as challenges such as time resource requirements.

Conclusions

Implementing an inpatient register for newborns and sick children through stakeholder engagement can effectively improve child health care services. Aside from challenges such as resource intensiveness and stakeholder commitments, success depended on the organising authority's expertise in relationship building, budget allocation, time management, and workforce dedication. Therefore, strategic planning, staff recruitment, networking, and budgeting are crucial for successful stakeholder engagement and health care initiatives.

Introducing a standardised register for strengthening the inpatient management of newborns and sick children: Implementation research in selected health facilities of Bangladesh

Background

It is imperative to maintain accurate documentation of clinical interventions aimed at enhancing the quality of care for newborns and sick children. The National Newborn Health and IMCI programme of Bangladesh led the development of a standardised register for managing newborns and sick children under five years of age during inpatient care through stakeholder engagement. We aimed to assess the implementation outcomes of the standardised register in the inpatient department.

Methods

We conducted implementation research in two district hospitals and two sub-district hospitals of Kushtia and Dinajpur districts from November 2022 to January 2023 to assess the implementation outcomes of the standardised register. We assessed the following World Health Organization implementation outcome variables: usability, acceptability, adoption (actual use), fidelity (completeness and accuracy), and utility (quality of care) of the register against preset benchmarks. We collected data through structured interviews with health care providers; participant enrolment; and data extraction from inpatient registers and case record forms.

Results

The average usability and acceptability scores among health care providers were 73 (standard deviation (SD) = 14) and 82 (SD = 14) out of 100, respectively. The inpatient register recorded 96% (95% confidence interval (CI) = 95-97) of under-five children who were admitted to the inpatient department (adoption - actual use). The proportions of completed data elements in the inpatient register were above the preset benchmark of 70% for all the assessed data elements except 'investigation done' (24%; 95% CI = 23-26) (fidelity - completeness). The percentage agreements between government-appointed nurses posted and study-appointed nurses were above the preset benchmark of 70% for all the reported variables (fidelity - accuracy). The kappa coefficient for the overall level of agreement between these two groups regarding reported variables indicated moderate to substantial agreement. The proportion of newborns with sepsis receiving injectable antibiotics was 62% (95% CI = 47-75) (utility - quality of care). We observed some variability in the completeness and accuracy of the inpatient register by district and facility type.

Conclusions

The inpatient register was positively received by health care providers, with evaluations of implementation outcome variables showing encouraging results. Our findings could inform evidence-based decision-making on the implementation and scale-up of the inpatient register in Bangladesh, as well as other low- and middle-income countries.

Disparities in the maternal healthcare continuum among Bangladeshi women: evidence from nationally representative surveys

INTRODUCTION

Utilisation of maternal healthcare is low, and it consistently decreases across antenatal to postnatal period in Bangladesh. However, there is paucity of knowledge in Bangladesh to understand gaps and associated factors in seeking continuum of maternal healthcare along the pathway. Therefore, we aimed to assess the trend in socioeconomic and demographic factors and wealth inequity in maternal CoC using the Bangladesh Multiple Indicator Cluster Survey (MICS).

METHODS

We performed a secondary analysis on nationally representative data from the last two MICS survey, carried out in 2012-13 and 2019. The study included women of reproductive age (15-49 years) with a live birth within two years preceding the survey. Total of 7,950 and 9,183 respondents were identified from these two surveys, respectively. We used multivariable logistic regression and concentration index to examine the covariates and inequity, respectively, in the utilisation of CoC.

RESULTS

Utilisation of ≥4 antenatal care, skilled delivery, and postnatal care for both mother and newborn increased from 13 percent in 2012-13 to 25 percent in 2019 survey. Moreover, wealth inequity persists favouring the rich in utilisation of CoC in Bangladesh. Women belonging to wealthier quintile, urban areas, and non-Muslim families, with higher education, a household head with higher education, media use, and fewer children were most likely to avail complete CoC in both the surveys.

CONCLUSION

Overall utilisation of maternal CoC increased between 2012 and 13 and 2019, however, women in Bangladesh still lack the CoC with persistent wealth inequality. Integrated provision of ANC, delivery by SBA, and PNC should be introduced, comprising both private and public health facilities, and targeting women in poor and rural communities. Efforts should also focus on women's education, autonomy, fertility rate, and exposure to media.

Magnitude and trends in inequalities in healthcare-seeking behavior for pneumonia and mortality rate among under-five children in Bangladesh: Evidence from nationwide cross-sectional survey 2007 to 2017

Background and Aims

Bangladesh did not have enough evidence on the current estimates and trend in inequities in the under-five mortality rate (U5MR). There is also a shortage of evidence on trends and inequalities in healthcare-seeking for pneumonia among under-five children (U5C) in Bangladesh. Hence, this study investigated the inequalities in U5MR and health care seeking for pneumonia in U5C through socioeconomic and geographic disparities in Bangladesh between 2007 and 2017.

Methods

Data from 2007, 2011, 2014, and 2017 Bangladesh Demographic and Health surveys were analyzed using the Health Equity Assessment Toolkit (HEAT) software by World Health Organization (WHO). The data on U5MR and healthcare-seeking for pneumonia were first disaggregated into five equity dimensions: wealth status, education, child sex, place of residence, and administrative divisions. Second, using summary metrics such as difference (D), population attributable risk (PAR), ratio (R), and population attributable fraction (PAF), inequalities were assessed.

Results

The U5MR declined from 73.9 deaths per 1000 live births in 2007 to 48.6 deaths in 2017, while the prevalence of healthcare-seeking for pneumonia in U5C fluctuated over time (34.6% in 2007, 35.4% in 2011, 42.0% in 2014, and 39.8% in 2017). Profound socioeconomic and geographic disparities in U5MR and the prevalence of healthcare-seeking for pneumonia in U5C favored the wealthy, educated, and urban residents. At the same time, the Sylhet division showed the worst situation for U5MR. There were also sex-related disparities in U5MR (PAR = -4.5, 95% confidence interval: -5.3 to -3.7) with higher risk among male children than females.

Conclusion

These results indicate that improving disadvantaged women, such as the poor, uneducated, and rural inhabitants, who exhibit disproportionate disparities in U5MR and healthcare-seeking behavior is important. To reduce childhood mortality, it is essential to improve healthcare-seeking for pneumonia among U5C. Facilitating women for better education and economic encompasses would help reducing disparity.

Beyond the regulatory radar: knowledge and practices of rural medical practitioners in Bangladesh

BACKGROUND

Informal and unregulated rural medical practitioners (RMPs) provide healthcare services to about two-thirds of people in Bangladesh, although their service is assumed to be substandard by qualified providers. As the RMPs are embedded in the local community and provide low-cost services, their practice pattern demands investigation to identify the shortfalls and design effective strategies to ameliorate the service.

METHODS

We conducted a cross-sectional study in 2015-16 using a convenient sample from all 64 districts of Bangladesh. Personnel practising modern medicine, without any recognized training, or with recognized training but practising outside their defined roles, and without any regulatory oversight were invited to take part in the study. Appropriateness of the diagnosis and the rationality of antibiotic and other drug use were measured as per the Integrated Management of Childhood Illness guideline.

RESULTS

We invited 1004 RMPs, of whom 877 consented. Among them, 656 (74.8%) RMPs owned a drugstore, 706 (78.2%) had formal education below higher secondary level, and 844 (96.2%) had informal training outside regulatory oversight during or after induction into the profession. The most common diseases encountered by them were common cold, pneumonia, and diarrhoea. 583 (66.5%) RMPs did not dispense any antibiotic for common cold symptoms. 59 (6.7%) and 64 (7.3%) of them could identify all main symptoms of pneumonia and diarrhoea, respectively. In pneumonia, 28 (3.2%) RMPs dispensed amoxicillin as first-line treatment, 819 (93.4%) dispensed different antibiotics including ceftriaxone, 721 (82.2%) dispensed salbutamol, and 278 (31.7%) dispensed steroid. In diarrhoea, 824 (94.0%) RMPs dispensed antibiotic, 937 (95.4%) dispensed ORS, 709 (80.8%) dispensed antiprotozoal, and 15 (1.7%) refrained from dispensing antibiotic and antiprotozoal together.

CONCLUSIONS

Inappropriate diagnoses, irrational use of antibiotics and other drugs, and polypharmacy were observed in the practising pattern of RMPs. The government and other stakeholders should acknowledge them as crucial partners in the healthcare sector and consider ways to incorporate them into curative and preventive care.

Research prioritisation on prevention and management of preterm birth in low and middle-income countries (LMICs) with a special focus on Bangladesh using the Child Health and Nutrition Research Initiative (CHNRI) method

Background

Fifteen million babies are born preterm globally each year, with 81% occurring in low- and middle-income countries (LMICs). Preterm birth complications are the leading cause of newborn deaths and significantly impact health, quality of life, and costs of health services. Improving outcomes for newborns and their families requires prioritising research for developing practical, scalable solutions, especially in low-resource settings such as Bangladesh. We aimed to identify research priorities related to preventing and managing preterm birth in LMICs for 2021-2030, with a special focus on Bangladesh.

Methods

We adopted the Child Health and Nutrition Research Initiative (CHNRI) method to set research priorities for preventing and managing preterm birth. Seventy-six experts submitted 490 research questions online, which we collated into 95 unique questions and sent for scoring to all experts. A hundred and nine experts scored the questions using five pre-selected criteria: answerability, effectiveness, deliverability, maximum potential for burden reduction, and effect on equity. We calculated weighted and unweighted research priority scores and average expert agreement to generate a list of top-ranked research questions for LMICs and Bangladesh.

Results

Health systems and policy research dominated the top 20 identified priorities for LMICs, such as understanding and improving uptake of the facility and community-based Kangaroo Mother Care (KMC), promoting breastfeeding, improving referral and transport networks, evaluating the impact of the use of skilled attendants, quality improvement activities, and exploring barriers to antenatal steroid use. Several of the top 20 questions also focused on screening high-risk women or the general population of women, understanding the causes of preterm birth, or managing preterm babies with illnesses (jaundice, sepsis and retinopathy of prematurity). There was a high overlap between research priorities in LMICs and Bangladesh.

Conclusions

This exercise, aimed at identifying priorities for preterm birth prevention and management research in LMICs, especially in Bangladesh, found research on improving the care of preterm babies to be more important in reducing the burden of preterm birth and accelerating the attainment of Sustainable Development Goal 3 target of newborn deaths, by 2030.

Levels and trends in mortality and causes of death among women of reproductive age in Bangladesh: Findings from three national surveys

Background

Information on the mortality rate and proportional cause-specific mortality is essential for identifying diseases of public health importance, design programmes, and formulating policies, but such data on women of reproductive age in Bangladesh is limited.

Methods

We analysed secondary data from the 2001, 2010, and 2016 rounds of the nationally representative Bangladesh Maternal Mortality and Health Care Survey (BMMS) to estimate mortality rates and causes of death among women aged 15-49 years. We collected information on causes of death three years prior to each survey using a country-adapted version of the World Health Organization (WHO) verbal autopsy (VA) questionnaire. Trained physicians independently reviewed the VA questionnaire and assigned a cause of death using the International Classification of Diseases (ICD) codes. The analysis included mortality rates and proportional mortality showing overall and age-specific causes of death.

Results

The overall mortality rates for women aged 15-49 years decreased over time, from 190 per 100 000 years of observation in the 2001 BMMS, to 121 per 100 000 in the 2010 BMMS, to 116 per 100 000 in the 2016 BMMS. Age-specific mortality showed a similar downward pattern. The three diseases contributing the most to mortality were maternal causes (13-20%), circulatory system diseases (15-23%), and malignancy (14-24%). The relative position of these three diseases changed between the three surveys. From the 2001 BMMS to the 2010 BMMS and subsequently to the 2016 BMMS, the number of deaths from non-communicable diseases (e.g. cardiovascular diseases and malignancies) increased from 29% to 38% to 48%. Maternal causes led to the highest proportion of deaths among 20-34-year-olds in all three surveys (25-32%), while suicide was the number one cause of death for teenagers (19-22%). Circulatory system diseases and malignancy were the two leading causes of death for older women aged 35-49 years (40%-67%).

Conclusions

There was a gradual shift in the causes of death from communicable to non-communicable diseases among women of reproductive age in Bangladesh. Suicide as the primary cause of death among teenage girls demands urgent attention for prevention.

Influencing factors associated with maternal delivery at home in urban areas: a cross-sectional analysis of the Bangladesh Demographic and Health Survey 2017-2018 data

BACKGROUND

The associated factors and patterns of giving birth in home settings of rural areas have been extensively studied in Bangladeshi literature. However, urban areas still need to be explored, particularly with recent data. Therefore, the authors aimed to investigate the influential determinants of delivery at home in urban areas of Bangladesh.

MATERIALS AND METHODS

In this study, 1699 urban-dwelling women who had given birth within the previous 60 months of the survey and lived in urban areas were used. The secondary data were extracted from the latest Bangladesh Demographic and Health Survey 2017-2018. Descriptive statistics and logistic regression were applied along with the association among selected variables were examined by the Chi-square test.

RESULTS

Findings depict that 36.49% of women who lived in urban areas of Bangladesh delivered at home, whereas, 63.51% delivered at different govt. and private health care facilities. Women who lived in Chittagong [adjusted odds ratio (AOR) = 2.11, 95% CI 1.24-3.60], Barisal [AOR = 2.05, 95% CI 1.16-3.64] and Sylhet [AOR = 1.92, 95% CI 1.08-3.43] divisions have more likelihood to deliver at home (36.85%). Urban women following Christian religion [AOR = 10.71, 95% CI 1.32-86.68] have higher odds of delivering child at home (0.47%). Urban women having three or more children before her latest delivery (22.37%) and who are employed (29.37%) have more likelihood to deliver at home. However, women aged between 25 and 34 years (43.50%), who have higher education (25.90%), play the role of household head (9.06%), have parity of more than two births (2.24%), and read daily newspapers (68.69%) had a lower chance of delivery at home. Furthermore, women from wealthier families (89.12%) and more antenatal care (ANC) visits (94.93%) were less likely to have a delivery at home.

CONCLUSION

Despite significant progress in women and reproductive health in Bangladesh, the proportion of delivery in the home in urban areas is alarming and should be emphasized more. The authors believe the identified factors will help design interventions and policy development on this issue.

Cohort profile: Bangladesh Cook Stove Pregnancy Cohort Study (CSPCS)

PURPOSE

The Cook Stove Pregnancy Cohort Study (CSPCS) was designed to assess the effects of biomass fuel use on household air pollution (HAP) as well as the effects of HAP (fine particulate matter, PM_2.5) on birth outcomes and acute lower respiratory infection (ALRI) among infants in Bangladesh.

PARTICIPANTS

We recruited 903 women within 18 weeks of pregnancy from rural and semiurban areas of Bangladesh between November 2016 and March 2017. All women and their infants (N=831 pairs) were followed until 12 months after delivery and a subset have undergone respiratory and gut microbiota analysis.

METHODS

Questionnaires were administered to collect detailed sociodemographic, medical, nutritional and behavioural information on the mother-child dyads. Anthropometric measurements and biological samples were also collected, as well as household PM_2.5 concentrations.

FINDINGS TO DATE

Published work in this cohort showed detrimental effects of biomass fuel and health inequity on birth outcomes. Current analysis indicates high levels of household PM_2.5 being associated with cooking fuel type and infant ALRI. Lastly, we identified distinct gut and respiratory microbial communities at 6 months of age.

FUTURE PLANS

This study provides an economical yet effective framework to conduct pregnancy cohort studies determining the health effects of adverse environmental exposures in low-resource countries. Future analyses in this cohort include assessing the effect of indoor PM_2.5 levels on (1) physical growth, (2) neurodevelopment, (3) age of first incidence and frequency of ALRI in infants and (4) the development of the respiratory and gut microbiome. Additional support has allowed us to investigate the effect of in utero exposure to metals on infant neurodevelopment in the first year of life.

Introducing pulse oximetry for outpatient management of childhood pneumonia: An implementation research adopting a district implementation model in selected rural facilities in Bangladesh

BACKGROUND

Pulse oximetry has potential for identifying hypoxaemic pneumonia and substantially reducing under-five deaths in low- and middle-income countries (LMICs) setting. However, there are few examples of introducing pulse oximetry in resource-constrained paediatric outpatient settings, such as Integrated Management of Childhood Illness (IMCI) services.

METHODS

The National IMCI-programme of Bangladesh designed and developed a district implementation model for introducing pulse oximetry in routine IMCI services through stakeholder engagement and demonstrated the model in Kushtia district adopting a health system strengthening approach. Between December 2020 and June 2021, two rounds of assessment were conducted based on WHO's implementation research framework and outcome variables, involving 22 IMCI service-providers and 1680 children presenting with cough/difficulty-in-breathing in 12 health facilities. The data collection procedures included structured-observations, re-assessments, interviews, and data-extraction by trained study personnel.

FINDINGS

We observed that IMCI service-providers conducted pulse oximetry assessments on all eligible children in routine outpatient settings, of which 99% of assessments were successful; 85% (95% CI 83,87) in one attempt, and 69% (95% CI 67,71) within one minute. The adherence to standard operating procedure related to pulse oximetry was 92% (95% CI 91,93), and agreement regarding identifying hypoxaemia was 97% (95% CI 96,98). The median performance-time was 36 seconds (IQR 20,75), which was longer among younger children (2-11 months: 44s, IQR 22,78; 12-59 months: 30s, IQR 18,53, p < 0.01) and among those classified as pneumonia/severe-pneumonia than as no-pneumonia (41s, IQR 22,70; 32s, IQR 20,62, p < 0.01). We observed improvements in almost all indicators in round-2. IMCI service-providers and caregivers showed positive attitudes towards using this novel technology for assessing their children.

INTERPRETATION

This implementation research study suggested the adoption, feasibility, fidelity, appropriateness, acceptability, and sustainability of pulse oximetry introduction in routine IMCI services in resource-poor settings. The learning may inform the evidence-based scale-up of pulse oximetry linked with an oxygen delivery system in Bangladesh and other LMICs.

FUNDING

This research was funded by the UK National Institute for Health Research (NIHR) (Global Health Research Unit on Respiratory Health (RESPIRE); 16/136/109) using UK aid from the UK Government to support global health research.

Success and time implications of SpO2 measurement through pulse oximetry among hospitalised children in rural Bangladesh: Variability by various device-, provider- and patient-related factors

Background

Hypoxaemia is one of the strongest predictors of mortality among children with pneumonia. It can be identified through pulse oximetry instantaneously, which is a non-invasive procedure but can be influenced by factors related to the specific measuring device, health provider and patient. Following WHO's global recommendation in 2014, Bangladesh decided to introduce pulse oximetry in paediatric outpatient services, ie, the Integrated Management of Childhood Illness (IMCI) services in 2019. A national committee updated the existing IMCI implementation package and decided to test it by assessing the pulse oximetry performance of different types of assessors in real-life inpatient settings.

Methods

We adopted an observational design and conducted a technology assessment among children admitted to a rural district hospital. Eleven nurses and seven paramedics received one-day training on pulse oximetry as assessors. Each assessor performed at least 30 pulse oximetry measurements on children with two types of handheld devices. The primary outcome of interest was obtaining a successful measurement of SpO2, defined as observing a stable (±1%) reading for at least 10 seconds. Performance time, ie, time taken to obtain a successful measurement of SpO2 was considered the secondary outcome of interest. In addition, we used Generalized Estimating Equation to assess the effect of different factors on the pulse oximetry performance.

Results

The assessors obtained successful measurements of SpO2 in all attempts (n = 1478) except one. The median time taken was 30 (interquartile range (IQR) = 22-42) seconds, and within 60 seconds, 92% of attempts were successful. The odds of obtaining a successful measurement within 60 seconds were 7.3 (95% confidence interval (CI) = 3.7-14.2) times higher with a Masimo device than a Lifebox device. Similarly, assessors aged >25 years were 4.8 (95% CI = 1.2, 18.6) times more likely to obtain a successful measurement within 60 seconds. The odds of obtaining a successful measurement was 2.6 (95% CI = 1.6, 4.2) times higher among children aged 12-59 months compared to 2-11 months.

Conclusions

Our study indicated that assessors could achieve the necessary skills to perform pulse oximetry successfully in real-life inpatient settings through a short training module, with some effect of device-, provider- and patient-related factors. The National IMCI Programme of Bangladesh can use these findings for finalising the national IMCI training modules and implementation package incorporating the recommendation of using pulse oximetry for childhood pneumonia assessment.

Introducing pulse oximetry in routine IMCI services in Bangladesh: A context-driven approach to influence policy and programme through stakeholder engagement

Background

Pneumonia is the leading cause of under-five child deaths globally and in Bangladesh. Hypoxaemia or low (<90%) oxygen concentration in the arterial blood is one of the strongest predictors of child mortality from pneumonia and other acute respiratory infections. Since 2014, the World Health Organization recommends using pulse oximetry devices in Integrated Management of Childhood Illness (IMCI) services (outpatient child health services), but it was not routinely used in most health facilities in Bangladesh until 2018. This paper describes the stakeholder engagement process embedded in an implementation research study to influence national policy and programmes to introduce pulse oximetry in routine IMCI services in Bangladesh.

Methods

Based on literature review and expert consultations, we developed a conceptual framework, which guided the planning and implementation of a 4-step stakeholder engagement process. Desk review, key informant interviews, consultative workshops and onsite demonstration were the key methods to involve and engage a wide range of stakeholders. In the first step, a comprehensive desk review and key informant interviews were conducted to identify stakeholder organisations and scored them based on their power and interest levels regarding IMCI implementation in Bangladesh. In the second step, two national level, two district level and five sub-district level sensitisation workshops were organised to orient all stakeholder organisations having high power or high interest regarding the importance of using pulse oximetry for pneumonia assessment and classification. In the third step, national and district level high power-high interest stakeholder organisations were involved in developing a joint action plan for introducing pulse oximetry in routine IMCI services. In the fourth step, led by a formal working group under the leadership of the Ministry of Health, we updated the national IMCI implementation package, including all guidelines, training manuals, services registers and referral forms in English and Bangla. Subsequently, we demonstrated its use in real-life settings involving various levels of (national, district and sub-district) stakeholders and worked alongside the government leaders towards carefully resuming activities despite the COVID-19 pandemic.

Results

Our engagement process contributed to the national decision to introduce pulse oximetry in routine child health services and update the national IMCI implementation package demonstrating country ownership, government leadership and multi-partner involvement, which are steppingstones towards scalability and sustainability. However, our experience clearly delineates that stakeholder engagement is a context-driven, time-consuming, resource-intensive, iterative, mercurial process that demands meticulous planning, prioritisation, inclusiveness, and adaptability. It is also influenced by the expertise, experience and positionality of the facilitating organization.

Conclusions

Our experience has demonstrated the value and potential of the approach that we adopted for stakeholder engagement. However, the approach needs to be conceptualised coupled with the allocation of adequate resources and time commitment to implement it effectively.

Unnecessary Cesarean Section Delivery Causes Risk to Both Mother and Baby: A Commentary on Pregnancy Complications and Women’s Health

In Bangladesh, 3.6 million babies are born each year. But the country is now facing a quickly rising rate of cesarean section (C-section) utilization. Here about 50% of total deliveries are institutional. Among them, two-thirds are in private care facilities, where the rate of C-sections is very high (83%). The present C-section rate is 2.5 times higher than in the previous decades. In Bangladesh, many physicians from private facilities are recommending C-section regardless of the mother’s physical condition and the position of the fetus. Therefore, mothers are more likely to choose C-section delivery who receive antenatal care from a private facility. Moreover, several socio-economic and demographic factors might be responsible for these increased C-section deliveries. Also, many private hospitals prefer C-section delivery due to their profit-making tendency. The unnecessary C-section delivery causes risk to both mother and baby Also, the high prevalence of C-section in Bangladesh is putting women’s health at risk. Therefore, the government healthcare authorities should ensure proper utilization of C-section facilities and encourage people for normal births at any health facility. Also, they can develop a national guideline for the use of C-sections and normal delivery depending on the physical condition of the mother and fetus.
