Setting research priorities to reduce global mortality from preterm birth and low birth weight by 2015

Predicting adverse birth outcome among childbearing women in Sub-Saharan Africa: employing innovative machine learning techniques

BACKGROUND

Adverse birth outcomes, including preterm birth, low birth weight, and stillbirth, remain a major global health challenge, particularly in developing regions. Understanding the possible risk factors is crucial for designing effective interventions for birth outcomes. Accordingly, this study aimed to develop a predictive model for adverse birth outcomes among childbearing women in Sub-Saharan Africa using advanced machine learning techniques. Additionally, this study aimed to employ a novel data science interpretability techniques to identify the key risk factors and quantify the impact of each feature on the model prediction.

METHODS

The study population involved women of childbearing age from 26 Sub-Saharan African countries who had given birth within five years before the data collection, totaling 139,659 participants. Our data source was a recent Demographic Health Survey (DHS). We utilized various data balancing techniques. Ten advanced machine learning algorithms were employed, with the dataset split into 80% training and 20% testing sets. Model evaluation was conducted using various performance metrics, along with hyperparameter optimization. Association rule mining and SHAP analysis were employed to enhance model interpretability.

RESULTS

Based on our findings, about 28.59% (95% CI: 28.36, 28.83) of childbearing women in Sub-Saharan Africa experienced adverse birth outcomes. After repeated experimentation and evaluation, the random forest model emerged as the top-performing machine learning algorithm, with an AUC of 0.95 and an accuracy of 88.0%. The key risk factors identified were home deliveries, lack of prenatal iron supplementation, fewer than four antenatal care (ANC) visits, short and long delivery intervals, unwanted pregnancy, primiparous mothers, and geographic location in the West African region.

CONCLUSION

The region continues to face persistent adverse birth outcomes, emphasizing the urgent need for increased attention and action. Encouragingly, advanced machine learning methods, particularly the random forest algorithm, have uncovered crucial insights that can guide targeted actions. Specifically, the analysis identifies risky groups, including first-time mothers, women with short or long birth intervals, and those with unwanted pregnancies. To address the needs of these high-risk women, the researchers recommend immediately providing iron supplements, scheduling comprehensive prenatal care, and strongly encouraging facility-based deliveries or skilled birth attendance.

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.

Health professional assisted Kangaroo mother care practice in Ethiopian health care facilities: evidence from the 2016 Ethiopian demographic and health survey

BACKGROUND

Worldwide, 15 million children born prematurely every year and over one million of them died because of prematurity caused complications. However, three-fourths of deaths from preterm related complications are preventable by using Kangaroo Mother Care (KMC). The Ethiopian government has been implementing a guideline that declares putting all low birth weight neonates at KMC. The aim of this study was to assess health professionals' assisted KMC practice and its associated factors among Ethiopian mothers who gave birth at health facilities.

METHODOLOGY

This study used the 2016Ethiopian Demographic and Health Survey data (EDHS). The 2016EDHS used a stratified two stage sampling method to select a representative sample using validated questioner. The sample we used in this study after cleaning the children's data set from the 2016EDHS was 2,960. Logistic regression model was used to assess the association of health professional assisted KMC practice and predictor variables.

RESULTS

Mothers who gave birth in health facilities and practiced kangaroo mother care were 1808(62.1%). In the multivariable logistic regression analysis, women from poorest (AOR, (95%CI)), (0.60, (0.43, 0.81)) and poorer (0.62, (0.46, 0.86)) socio-economic status were not practicing KMC.

CONCLUSIONS

The coverage of health professional assisted KMC practice was far lower than the expectation for mothers who gave birth in health facilities (100%). Low socio-economic status was associated with not practicing KMC. A further study on why mothers from low wealth index did not practicing KMC while they were in health facilities may be needed.

Research priorities for maternal and perinatal health clinical trials and methods used to identify them: A systematic review

OBJECTIVE

Research prioritisation helps to target research resources to the most pressing health and healthcare needs of a population. This systematic review aimed to report research priorities in maternal and perinatal health and to assess the methods that were used to identify them.

METHODS

A systematic review was undertaken. Projects that aimed to identify research priorities that were considered to be amenable to clinical trials research were eligible for inclusion. The search, limited to the last decade and publications in English, included MEDLINE, EMBASE, CINHAL, relevant Cochrane priority lists, Cochrane Priority Setting Methods Group homepage, James Lind Alliance homepage, Joanna Brigg's register, PROSPERO register, reference lists of all included articles, grey literature, and the websites of relevant professional bodies, until 13 October 2020. The methods used for prioritisation were appraised using the Reporting Guideline for Priority Setting of Health Research (REPRISE).

FINDINGS

From the 62 included projects, 757 research priorities of relevance to maternal and perinatal health were identified. The most common priorities related to healthcare systems and services, pregnancy care and complications, and newborn care and complications. The least common priorities related to preconception and postpartum health, maternal mental health, contraception and pregnancy termination, and fetal medicine and surveillance. The most commonly used prioritisation methods were Delphi (20, 32%), Child Health Nutrition Research Initiative (17, 27%) and the James Lind Alliance (10, 16%). The fourteen projects (23%) that reported on at least 80% of the items included in the REPRISE guideline all used an established research prioritisation method.

CONCLUSIONS

There are a large number of diverse research priorities in maternal and perinatal health that are amenable to future clinical trials research. These have been identified by a variety of research prioritisation methods.

Kangaroo Mother Care in Vietnam: A National Survey of a Middle-Income Country

Background: Kangaroo mother care (KMC) is a low-cost intervention that is indicated to be a highly effective practice for which adoption and implementation are lacking. We investigated the current provision of KMC in Vietnam and explored differences among levels of healthcare facility. Methods: A survey form was sent to 187 hospitals in Vietnam, representing the three levels (central, provincial and district) of public hospital-based maternity services. Results: Overall response rate was 74% (138/187 hospitals). Routine KMC implementation was estimated in 49% of the hospitals. Where KMC was implemented or was being introduced, half of the hospitals had a written protocol and a KMC-dedicated room, and held educational courses on KMC. KMC was mainly performed by the mother. Skin-to-skin contact was mostly performed for <12 h/day (55%), exclusive breastfeeding at discharge was very frequent (89%) and early discharge was considered in half of the hospitals (54%), while follow-up was not performed in 29% of the hospitals. Participants considered follow-up after discharge as the main barrier to KMC implementation, and indicated education (of both parents and health caregivers) and environment upgrades (KMC-dedicated room and equipment) as the most important facilitators. Conclusions: Our survey estimated a limited implementation of KMC in Vietnamese maternity hospitals, with marked variations across the different levels of maternity services. Areas of improvements include increasing the duration of skin-to-skin contact, arranging dedicated spaces for KMC, involving the relatives (especially at district level), extending the availability of a written protocol, improving the eligibility process, and implementing early discharge and follow-up monitoring.

Evidence for Global Health Care Interventions for Preterm or Low Birth Weight Infants: An Overview of Systematic Reviews

CONTEXT

Twenty-four research questions (framed as population, intervention, comparator, and outcomes) for global health care interventions for preterm and low birth weight (LBW) infants were identified at a World Health Organization guideline development group expert meeting in December 2020.

OBJECTIVE

To describe which systematic reviews had addressed these research questions in the last 3 years.

DATA SOURCES

Medline (Ovid); the Cochrane Database of Systematic Reviews; the Cochrane Database of Systematic Review Protocols; and the PROSPERO International prospective register of systematic reviews databases from January 1, 2019 to December 31, 2021 were used.Randomized controlled trials or observational studies. Two reviewers independently extracted data.

RESULTS

We found 9 systematic reviews. Eight reviews of 121 studies and 25 465 preterm or LBW infants published in the last 36 months "fully" addressed 8 of our 24 research questions (donor human milk, multicomponent fortifier, formula milk, probiotics, emollients, continuous positive airways pressure [CPAP] any, CPAP early, CPAP prophylactic); and 1 systematic review found no trials (mother's own milk). All received a "high" AMSTAR quality rating. Fifteen research questions (kangaroo mother care, early initiation, responsive feeding, advancement, exclusive breastfeeding duration, iron, zinc, vitamin D, vitamin A, calcium and phosphorous, multiple micronutrients, CPAP pressure source, methyl xanthines, family involvement, and family support) had no systematic review. Limitations include that we restricted our search to those interventions identified as a priority at a World Health Organization scoping meeting. Other interventions that may be of importance to preterm or LBW infants were not able to be considered.

CONCLUSIONS

Almost a third of our research questions were addressed by high quality systematic reviews. We found gaps in thermal care, feeding, and familysupport interventions, which need to be addressed.

Evaluation of SIMESON, a training program to improve access to quality health care for pregnant women and newborn in different healthcare facilities of northern Bangladesh

Aim

The study aims to explore the current knowledge and skills of healthcare providers already trained by SIMESON (simulation for essential skills for obstetrical and neonatal care), in reviewing perinatal health situations including current status of healthcare facilities and cost estimation.

Design

It was an observational study.

Methods

Cost estimation following both quantitative and qualitative approaches was also attempted.

Result

Knowledge and skills of 88 healthcare providers about the provision of normal delivery and immediate postpartum care, management of postpartum haemorrhage (PPH), retained placenta and use of bag and mask ventilation to help a baby breathe were found to be considerably strengthened following SIMESON training. During the 6 months after training, there were 477 PPH cases managed successfully with only one death; neonatal deaths observed were 6.6/1,000 live births; twice the number of facility deliveries; and 80% use rate of Ambu bag for helping baby breathe. The estimated cost per trainee was 395.68 USD, and 5.85 USD per beneficiary.

Determinants of adverse birth outcome in Sub-Saharan Africa: analysis of recent demographic and health surveys

Background

More than 75% of neonatal deaths occurred in the first weeks of life as a result of adverse birth outcomes. Low birth weight, preterm births are associated with a variety of acute and long-term complications. In Sub-Saharan Africa, there is insufficient evidence of adverse birth outcomes. Hence, this study aimed to determine the pooled prevalence and determinants of adverse birth outcomes in Sub-Saharan Africa.

Method

Data of this study were obtained from a cross-sectional survey of the most recent Demographic and Health Surveys (DHS) of ten Sub-African (SSA) countries. A total of 76,853 children born five years preceding the survey were included in the final analysis. A Generalized Linear Mixed Models (GLMM) were fitted and an adjusted odds ratio (AOR) with a 95% Confidence Interval (CI) was computed to declare statistically significant determinants of adverse birth outcomes.

Result

The pooled prevalence of adverse birth outcomes were 29.7% (95% CI: 29.4 to 30.03). Female child (AOR = 0.94, 95%CI: 0.91 0.97), women attended secondary level of education (AOR = 0.87, 95%CI: 0.82 0.92), middle (AOR = 0.94,95%CI: 0.90 0.98) and rich socioeconomic status (AOR = 0.94, 95%CI: 0.90 0.99), intimate-partner physical violence (beating) (AOR = 1.18, 95%CI: 1.14 1.22), big problems of long-distance travel (AOR = 1.08, 95%CI: 1.04 1.11), antenatal care follow-ups (AOR = 0.86, 95%CI: 0.83 0.86), multiparty (AOR = 0.88, 95%CI: 0.84 0.91), twin births (AOR = 2.89, 95%CI: 2.67 3.14), and lack of women involvement in healthcare decision-making process (AOR = 1.10, 95%CI: 1.06 1.13) were determinants of adverse birth outcomes.

Conclusion

This study showed that the magnitude of adverse birth outcomes was high, abnormal baby size and preterm births were the most common adverse birth outcomes. This finding suggests that encouraging antenatal care follow-ups and socio-economic conditions of women are essential. Moreover, special attention should be given to multiple pregnancies, improving healthcare accessibilities to rural areas, and women’s involvement in healthcare decision-making.

Setting research priorities for sexual, reproductive, maternal, newborn, child and adolescent health in humanitarian settings

Background

An estimated 70.8 million people are forcibly displaced worldwide, 75% of whom are women and children. Prioritizing a global research agenda to inform guidance, service delivery, access to and quality of services is essential to improve the survival and health of women, children and adolescents in humanitarian settings.

Method

A mixed-methods design was adapted from the Child Health and Nutrition Research Initiative (CHNRI) methodology to solicit priority research questions across the sexual, reproductive, maternal, newborn, child and adolescent health (SRMNCAH) domains in humanitarian settings. The first step (CHNRI) involved data collection and scoring of perceived priority questions, using a web-based survey over two rounds (first, to generate the questions and secondly, to score them). Over 1000 stakeholders from across the globe were approached; 177 took part in the first survey and 69 took part in the second. These research questions were prioritized by generating a research prioritization score (RPP) across four dimensions: answerability, program feasibility, public health relevance and equity. A Delphi process of 29 experts followed, where the 50 scored and prioritized CHRNI research questions were shortlisted. The top five questions from the CHNRI scored list for each SRMNCAH domain were voted on, rendering a final list per domain.

Results

A total of 280 questions were generated. Generated questions covered sexual and reproductive health (SRH) (n = 90, 32.1%), maternal health (n = 75, 26.8%), newborn health (n = 42, 15.0%), child health (n = 43, 15.4%), and non-SRH aspects of adolescent health (n = 31, 11.1%). A shortlist of the top ten prioritized questions for each domain were generated on the basis of the computed RPPs. During the Delphi process, the prioritized questions, based on the CHNRI process, were further refined. Five questions from the shortlist of each of the SRMNCAH domain were formulated, resulting in 25 priority questions across SRMNCAH. For example, one of the prioritized SRH shortlisted and prioritized research question included: “What are effective strategies to implement good quality comprehensive contraceptive services (long-acting, short-acting and EC) for women and girls in humanitarian settings?”

Conclusion

Data needs, effective intervention strategies and approaches, as well as greater efficiency and quality during delivery of care in humanitarian settings were prioritized. The findings from this research provide guidance for researchers, program implementers, as well as donor agencies on SRMNCAH research priorities in humanitarian settings. A global research agenda could save the lives of those who are at greatest risk and vulnerability as well as increase opportunities for translation and innovation for SRMNCAH in humanitarian settings.

Duration and quality of sleep during pregnancy are associated with preterm birth and small for gestational age: A prospective study

OBJECTIVE

To explore the associations of duration and quality of sleep during pregnancy with preterm birth and small for gestational age (SGA).

METHODS

A prospective study was carried out on 1082 healthy women with singleton pregnancies from Chengdu, China. Self-report questionnaires, including duration and quality of sleep and other information, were administered at 8-12, 24-28, and 32-36 weeks of pregnancy. Data on gestational age and weight and length of the neonates were recorded after delivery. After controlling the potential confounders, a multivariable logistic regression model was performed to evaluate whether duration and quality of sleep were associated with preterm birth and SGA.

RESULTS

Participants with short duration of sleep during the third trimester were more likely to report preterm birth (odds ratio [OR] 2.16, 95% confidence interval [CI] 1.26-4.81) and SGA (OR 2.67, 95% CI 1.18-6.54). Participants with poor quality of sleep during the third trimester were at high risk for preterm birth (OR 2.26, 95% CI 1.29-5.84) and SGA (OR 2.08, 95% CI 1.19-5.38).

CONCLUSION

Short duration and poor quality of sleep during pregnancy are associated with an increased risk of preterm birth and SGA. Sleep characteristics should be assessed during prenatal evaluations to decrease adverse maternal and fetal outcomes.

Measuring newborn foot length to estimate gestational age in a high risk Northwest Ethiopian population

Introduction

Preterm birth is defined as all births before 37 completed weeks of gestation. Globally, the prevalence rate of preterm birth ranges from 47.5 to 137 per 1000 live births. In Ethiopia, the prevalence of preterm birth is 10.1%. Several anthropometric parameters, particularly, head circumference and foot length(FL) have been used as a proxy measure for gestational age(GA).

Objective

To assess the use of newborn foot length as a screening tool to identify preterm newborns and correlation factors at the University of Gondar Comprehensive Specialized Hospital (UOG CSH), Northwest Ethiopia.

Methods

Institutional based cross-sectional study design was conducted on 205 newborns admitted to a neonatal intensive care unit, UOG CSH. Systematic sampling technique was employed. Optimal cutoff newborn foot length and area under the curve (AUC) was calculated by the receiver operating characteristic curve analysis to assess the power of foot length measurement to diagnosis prematurity.

Results

The mean foot length was 7.41±0.67 cm with a range of 5.4–8.6 cm. Gestational age had a significant strong positive correlation with foot length(r = 0.865). The regression equation derived was GA = 4.5*FL + 3.61. Foot length had strong power (AUC = 0.99) to differentiate preterm from term newborns. A threshold newborn foot length of ≤7.35 cm had a sensitivity and specificity of 98.5% and 96.3%, respectively to predict prematurity.

Conclusion

Foot length had a high sensitivity and specificity in identifying preterm newborns, making it a reliable tool to identify preterm birth in a rural setting.

Immediate parent-infant skin-to-skin study (IPISTOSS): study protocol of a randomised controlled trial on very preterm infants cared for in skin-to-skin contact immediately after birth and potential physiological, epigenetic, psychological and neurodevelopmental consequences

INTRODUCTION

In Scandinavia, 6% of infants are born preterm, before 37 gestational weeks. Instead of continuing in the in-utero environment, maturation needs to occur in a neonatal unit with support of vital functions, separated from the mother's warmth, nutrition and other benefits. Preterm infants face health and neurodevelopment challenges that may also affect the family and society at large. There is evidence of benefit from immediate and continued skin-to-skin contact (SSC) for term and moderately preterm infants and their parents but there is a knowledge gap on its effect on unstable very preterm infants when initiated immediately after birth.

METHODS AND ANALYSIS

In this ongoing randomised controlled trial from Stavanger, Norway and Stockholm, Sweden, we are studying 150 infants born at 28+0 to 32+6 gestational weeks, randomised to receive care immediately after birth in SSC with a parent or conventionally in an incubator. The primary outcome is cardiorespiratory stability according to the stability of the cardiorespiratory system in the preterm score. Secondary outcomes are autonomic stability, thermal control, infection control, SSC time, breastfeeding and growth, epigenetic profile, microbiome profile, infant behaviour, stress resilience, sleep integrity, cortical maturation, neurodevelopment, mother-infant attachment and attunement, and parent experience and mental health.

ETHICS AND DISSEMINATION

The study has ethical approval from the Swedish Ethical Review Authority (2017/1135-31/3, 2019-03361) and the Norwegian Regional Ethical Committee (2015/889). The study is conducted according to good clinical practice and the Helsinki declaration. The results of the study will increase the knowledge about the mechanisms behind the effects of SSC for very preterm infants by dissemination to the scientific community through articles and at conferences, and to the society through parenting classes and magazines.

STUDY STATUS

Recruiting since April 2018. Expected trial termination June 2021.

TRIAL REGISTRATION NUMBER

NCT03521310 (ClinicalTrials.gov).

Top research priorities for preterm birth: results of a prioritisation partnership between people affected by preterm birth and healthcare professionals

Background

We report a process to identify and prioritise research questions in preterm birth that are most important to people affected by preterm birth and healthcare practitioners in the United Kingdom and Republic of Ireland.

Methods

Using consensus development methods established by the James Lind Alliance, unanswered research questions were identified using an online survey, a paper survey distributed in NHS preterm birth clinics and neonatal units, and through searching published systematic reviews and guidelines. Prioritisation of these questions was by online voting, with paper copies at the same NHS clinics and units, followed by a decision-making workshop of people affected by preterm birth and healthcare professionals.

Results

Overall 26 organisations participated. Three hundred and eighty six people responded to the survey, and 636 systematic reviews and 12 clinical guidelines were inspected for research recommendations. From this, a list of 122 uncertainties about the effects of treatment was collated: 70 from the survey, 28 from systematic reviews, and 24 from guidelines. After removing 18 duplicates, the 104 remaining questions went to a public online vote on the top 10. Five hundred and seven people voted; 231 (45%) people affected by preterm birth, 216 (43%) health professionals, and 55 (11%) affected by preterm birth who were also a health professional. Although the top priority was the same for all types of voter, there was variation in how other questions were ranked.

Following review by the Steering Group, the top 30 questions were then taken to the prioritisation workshop. A list of top 15 questions was agreed, but with some clear differences in priorities between people affected by preterm birth and healthcare professionals.

Conclusions

These research questions prioritised by a partnership process between service users and healthcare professionals should inform the decisions of those who plan to fund research. Priorities of people affected by preterm birth were sometimes different from those of healthcare professionals, and future priority setting partnerships should consider reporting these separately, as well as in total.

Using research priority-setting to guide bridging the implementation gap in countries - a case study of the Uganda newborn research priorities in the SDG era

Background

One of the greatest challenges that countries face regarding the achievement of the Sustainable Development Goal (SDG) targets for child health regard the actions required to improve neonatal health; these interventions have to be informed by evidence. In view of the persisting high numbers of newborn deaths in Uganda, we aimed to define a locally contextualised national research agenda for newborn health to guide national investments towards SDG targets.

Methods

We adopted a systematic approach for priority-setting adapted from the Child Health and Nutrition Research Initiative. We identified and listed local newborn researchers and experts in Uganda by reviewing the PubMed database, through a snowballing technique, and engaged the Ministry of Health. Participants were requested to generate at least three research questions. The collated questions were sent to the same expert group to be rated using five criteria, including answerability, scalability, impact, generalisability and speed.

Findings

Of the 300 researchers and stakeholders contacted, 104 responded (36%) and generated 304 questions. These questions were collated and duplicates removed giving a condensed list of 41 research questions. These questions were then rated by 82 experts. Of the top 15 research questions, 86.7% (13/15) were in the service delivery and 6.7% (1/15) in the development domain, while only 6.7% (1/15) was in the group ‘other’. None of the leading 15 questions was in the discovery domain. Strategies to improve quality of intrapartum care featured high in the responses, while research around care for premature babies was not a perceived focus of research.

Conclusions

The focus of improved evidence to guide and innovate service delivery, foremost intrapartum care, reflects the importance of this area as accelerated improvement is likely to yield fast and sustained survival gains in the neonatal period and beyond in Uganda. We recommend that other countries adapt a similar approach in defining priority reproductive, maternal, newborn and child health areas for investment in order to accelerate progress towards achieving the SDGs.

Reinforcing kangaroo mother care uptake in resource limited settings

Background

The national and global coverage of kangaroo mother care (KMC) remains low. Hence, adjuncts to KMC may be necessary, especially on day1 of life when neonatal mortality is high. It is important to provide warmth and reduce mortality in preterm low birth weight (LBW) infants in the community/hospital setting. In this manuscript, the outcome of using a Styrofoam box (SB) for LBW infants in various situations in India, such as in a home-setting in tribal/extra-remote areas, at a primary health center in tribal/extra-remote areas and at a referral hospital, is presented. It is suggested that use of an SB may complement KMC.

The study

In this retrospective observational study, an SB (50 × 36 × 25 cm, weight: 500 g) was used in diverse settings: a) as a home incubator in the early neonatal period, b) for providing warmth after hospital discharge and c) as a transport incubator for home-to-hospital and inter-hospital transportation.a) All six infants, presenting on day 1 of life with a foot length of less than 6.5 cm, remained warm and survived when the box was used as a home incubator. b) The babies discharged from hospital (N = 7) were warm in the box at the home setting. c) Use of the box as a home-to-hospital transport incubator improved the number of referrals from 13 to 24 in one year. d) Oxygen saturations were well-maintained and hypothermia did not occur in any infant during inter-hospital transfers when oxygen was administered in the SB. e) The concentration of oxygen delivered was predictable and was well maintained when administered to infants in the SB. The acceptance of the use of an SB by the parents was beneficial.

Conclusion

An SB may be used to complement KMC in resource-limited settings. Well-designed studies are required to confirm the safety and efficacy of this approach in reducing neonatal hypothermia, morbidity, and mortality.

Moving from formative research to co-creation of interventions: insights from a community health system project in Mozambique, Nepal and Peru

Different methodological approaches for implementation research in global health focusing on how interventions are developed, implemented and evaluated are needed. In this paper, we detail the approach developed and implemented in the COmmunity HEalth System InnovatiON (COHESION) Project, a global health project aimed at strengthening health systems in Mozambique, Nepal and Peru. This project developed innovative formative research at policy, health system and community levels to gain a comprehensive understanding of the barriers, enablers, needs and lessons for the management of chronic disease using non-communicable and neglected tropical diseases as tracer conditions. After formative research, COHESION adopted a co-creation approach in the planning of interventions. The approach included two interactions with each type of stakeholder at policy, health system and community level in each country which aimed to develop interventions to improve the delivery of care of the tracer conditions. Diverse tools and methods were used in order to prioritise interventions based on support, resources and impact. Additionally, a COHESION score that assessed feasibility, sustainability and scaling up was used to select three potential interventions. Next steps for the COHESION Project are to further detail and develop the interventions propositioned through this process. Besides providing some useful tools and methods, this work also highlights the challenges and lessons learned from such an approach.

What is kangaroo mother care? Systematic review of the literature

BACKGROUND

Kangaroo mother care (KMC), often defined as skin-to-skin contact between a mother and her newborn, frequent or exclusive breastfeeding, and early discharge from the hospital has been effective in reducing the risk of mortality among preterm and low birth weight infants. Research studies and program implementation of KMC have used various definitions.

OBJECTIVES

To describe the current definitions of KMC in various settings, analyze the presence or absence of KMC components in each definition, and present a core definition of KMC based on common components that are present in KMC literature.

METHODS

We conducted a systematic review and searched PubMed, Embase, Scopus, Web of Science, and the World Health Organization Regional Databases for studies with key words "kangaroo mother care", "kangaroo care" or "skin to skin care" from 1 January 1960 to 24 April 2014. Two independent reviewers screened articles and abstracted data.

FINDINGS

We screened 1035 articles and reports; 299 contained data on KMC and neonatal outcomes or qualitative information on KMC implementation. Eighty-eight of the studies (29%) did not define KMC. Two hundred and eleven studies (71%) included skin-to-skin contact (SSC) in their KMC definition, 49 (16%) included exclusive or nearly exclusive breastfeeding, 22 (7%) included early discharge criteria, and 36 (12%) included follow-up after discharge. One hundred and sixty-seven studies (56%) described the duration of SSC.

CONCLUSIONS

There exists significant heterogeneity in the definition of KMC. A large number of studies did not report definitions of KMC. Skin-to-skin contact is the core component of KMC, whereas components such as breastfeeding, early discharge, and follow-up care are context specific. To implement KMC effectively development of a global standardized definition of KMC is needed.

How Schools Can Promote Healthy Development for Newly Arrived Immigrant and Refugee Adolescents: Research Priorities

BACKGROUND

The US education system must find creative and effective ways to foster the healthy development of the approximately 2 million newly arrived immigrant and refugee adolescents, many of whom contend with language barriers, limited prior education, trauma, and discrimination. We identify research priorities for promoting the school success of these youth.

METHODS

The study used the 4-phase priority-setting method of the Child Health and Nutrition Research Initiative. In the final stage, 132 researchers, service providers, educators, and policymakers based in the United States were asked to rate the importance of 36 research options.

RESULTS

The highest priority research options (range 1 to 5) were: evaluating newcomer programs (mean = 4.44, SD = 0.55), identifying how family and community stressors affect newly arrived immigrant and refugee adolescents' functioning in school (mean = 4.40, SD = 0.56), identifying teachers' major stressors in working with this population (mean = 4.36, SD = 0.72), and identifying how to engage immigrant and refugee families in their children's education (mean = 4.35, SD = 0.62).

CONCLUSION

These research priorities emphasize the generation of practical knowledge that could translate to immediate, tangible benefits for schools. Funders, schools, and researchers can use these research priorities to guide research for the highest benefit of schools and the newly arrived immigrant and refugee adolescents they serve.

Setting an implementation research agenda for Canadian investments in global maternal, newborn, child and adolescent health: a research prioritization exercise

BACKGROUND

Improving global maternal, newborn, child and adolescent health (MNCAH) is a top development priority in Canada, as shown by the $6.35 billion in pledges toward the Muskoka Initiative since 2010. To guide Canadian research investments, we aimed to systematically identify a set of implementation research priorities for MNCAH in low- and middle-income countries.

METHODS

We adapted the Child Health and Nutrition Research Initiative method. We scanned the Child Health and Nutrition Research Initiative literature and extracted research questions pertaining to delivery of interventions, inviting Canadian experts on MNCAH to generate additional questions. The experts scored a combined list of 97 questions against 5 criteria: answerability, feasibility, deliverability, impact and effect on equity. These questions were ranked using a research priority score, and the average expert agreement score was calculated for each question.

RESULTS

The overall research priority score ranged from 40.14 to 89.25, with a median of 71.84. The average expert agreement scores ranged from 0.51 to 0.82, with a median of 0.64. Highly-ranked research questions varied across the life course and focused on improving detection and care-seeking for childhood illnesses, overcoming barriers to intervention uptake and delivery, effectively implementing human resources and mobile technology, and increasing coverage among at-risk populations. Children were the most represented target population and most questions pertained to interventions delivered at the household or community level.

INTERPRETATION

Investing in implementation research is critical to achieving the Sustainable Development Goal of ensuring health and well-being for all. The proposed research agenda is expected to drive action and Canadian research investments to improve MNCAH.

Enhancing neonatal survival: what can we do today?

OBJECTIVE

Neonatal deaths account for 44% of the world's under-5 child mortality. Over half of all neonatal deaths globally occur in preterm babies. Therefore, improving care of a preterm baby is particularly important to reduce under-5 mortality. The objective of this study was to spell out components of care of preterm/low birth weight babies at first level health facility and at first referral unit (FRU) in low resource settings.

STUDY DESIGN

We have analyzed weight-wise survivals at two hospitals attached to medical colleges, J.J. Hospital, Mumbai and General Hospital, Talegaon, and at Rural Hospital, Dahanu. There were three-tier interventions: (i) warmth+ feeding and antibiotics, (ii) improved care at birth plus increased oxygen availability and (iii) use of dopamine. J.J. Hospital went through all these stages one after another; General Hospital had all three going simultaneously. The Rural Hospital had a 1+2.

RESULTS

During 1978 to 1984, J.J. Hospital saved 50 to 55% very low birth weight (VLBW) babies by providing warmth, feeding and antibiotics. This percentage increased to 56 to 58%, when adequate oxygen and good care at birth was available (1984 to 1989). For babies in the moderately low birth weight category (MLBW), 1500 to 2000 g at birth, the corresponding figures were 56 to 58% and 84 to 86%. The same interventions led to statistically significant decline in MLBW and VLBW categories at General Hospital, Talegaon (2010 to 2013). The Rural Hospital, Dahanu (1987 to 1992) achieved better survival rates in VLBW (61.5%) and MLBW (92.5%) categories with identical interventions and less staff.

CONCLUSION

On the basis of our results, we suggest that in resource-limited settings, the first level health facility may be able to look after short-stay babies that weigh more than 1500 g and that have no respiratory distress. The FRU may look after MLBW babies, with or without respiratory distress, and VLBW babies without respiratory distress by giving special care.

Interpregnancy interval and perinatal outcomes across Latin America from 1990 to 2009: a large multi-country study

OBJECTIVE

To determine the relationship of interpregnancy interval with maternal and offspring outcomes.

DESIGN

Retrospective study with data from the Perinatal Information System database of the Latin American Centre for Perinatology and Human Development, Uruguay.

SETTING

Latin America, 1990-2009.

POPULATION

A cohort of 894 476 women delivering singleton infants.

METHODS

During 1990-2009 the Perinatal Information System database of the Latin American Centre for Perinatology identified 894 476 women with defined interpregnancy intervals: i.e. the time elapsed between the date of the previous delivery and the first day of the last normal menstrual period for the index pregnancy. Using the interval 12-23 months as the reference category, multiple logistic regression estimated adjusted odds ratios (aORs) with 95% confidence intervals (95% CIs) of the association between various interval lengths and maternal and offspring outcomes.

MAIN OUTCOME MEASURES

Maternal death, pre-eclampsia, eclampsia, puerperal infection, fetal death, neonatal death, preterm birth, and low birthweight.

RESULTS

In the reference interval there was 0.05% maternal death, 1.00% postpartum haemorrhage, 2.80% pre-eclampsia, 0.15% eclampsia, 0.28% puerperal infection, 3.45% fetal death, 0.68% neonatal death, 12.33% preterm birth, and 9.73% low birthweight. Longer intervals had increased odds of pre-eclampsia (>72 months), fetal death (>108-119 months), and low birthweight (96-107 months). Short intervals of <12 months had increased odds of pre-eclampsia (aOR 0.80; 95% CI 0.76-0.85), neonatal death (aOR 1.18; 95% CI 1.08-1.28), and preterm birth (aOR 1.16; 95% CI 1.11-1.21). Statistically, the interval had no relationship with maternal death, eclampsia, and puerperal infection.

CONCLUSIONS

A short interpregnancy interval of <12 months is associated with pre-eclampsia, neonatal mortality, and preterm birth, but not with other maternal or offspring outcomes. Longer intervals of >72 months are associated with pre-eclampsia, fetal death, and low birthweight, but not with other maternal or offspring outcomes.

TWEETABLE ABSTRACT

A short interpregnancy interval of <12 months is associated with neonatal mortality and preterm birth.

Early neonatal deaths with perinatal asphyxia in very low birth weight Brazilian infants

OBJECTIVE

The objective of this study was to assess the frequency of early deaths associated with birth asphyxia of very low birth weight infants between 2005 and 2010, in Brazil.

STUDY DESIGN

This population study enrolled all live births with birth weight from 400 to 1499 g, gestational age ⩾ 22 weeks, without malformations that died up to 6 days after birth with perinatal asphyxia. Asphyxia was defined if intrauterine hypoxia, asphyxia at birth or meconium aspiration syndrome were written in any line of the death certificate. Active search was carried out in 27 Brazilian federative units.

RESULT

For every 1000 live births of very low birth weight infants without congenital malformations, 40.25 and 32.38 died with birth asphyxia in the first week after birth, respectively, in 2005 and 2010 (P<0.001). The contribution of birth asphyxia to early neonatal death of these infants was approximately 10 to 12% all study years.

CONCLUSION

Reduction of birth asphyxia in very low birth weight infants is essential to reducing neonatal mortality in Brazil.

How are health research priorities set in low and middle income countries? A systematic review of published reports

BACKGROUND

Priority setting is increasingly recognised as essential for directing finite resources to support research that maximizes public health benefits and drives health equity. Priority setting processes have been undertaken in a number of low- and middle-income country (LMIC) settings, using a variety of methods. We undertook a critical review of reports of these processes.

METHODS AND FINDINGS

We searched electronic databases and online for peer reviewed and non-peer reviewed literature. We found 91 initiatives that met inclusion criteria. The majority took place at the global level (46%). For regional or national initiatives, most focused on Sub Saharan Africa (49%), followed by East Asia and Pacific (20%) and Latin America and the Caribbean (18%). A quarter of initiatives aimed to cover all areas of health research, with a further 20% covering communicable diseases. The most frequently used process was a conference or workshop to determine priorities (24%), followed by the Child Health and Nutrition Initiative (CHNRI) method (18%). The majority were initiated by an international organization or collaboration (46%). Researchers and government were the most frequently represented stakeholders. There was limited evidence of any implementation or follow-up strategies. Challenges in priority setting included engagement with stakeholders, data availability, and capacity constraints.

CONCLUSIONS

Health research priority setting (HRPS) has been undertaken in a variety of LMIC settings. While not consistently used, the application of established methods provides a means of identifying health research priorities in a repeatable and transparent manner. In the absence of published information on implementation or evaluation, it is not possible to assess what the impact and effectiveness of health research priority setting may have been.

The reliability of a newborn foot length measurement tool used by community volunteers to identify low birth weight or premature babies born at home in southern Tanzania

Background

Low birthweight babies need extra care, and families need to know whether their newborn is low birthweight in settings where many births are at home and weighing scales are largely absent. In the context of a trial to improve newborn health in southern Tanzania, a counselling card was developed that incorporated a newborn foot length measurement tool to screen newborns for low birth weight and prematurity. This was used by community volunteers at home visits and shows a scale picture of a newborn foot with markers for a ‘short foot’ (<8 cm). The tool built on previous hospital based research that found newborn foot length <8 cm to have sensitivity and specificity to identify low birthweight (<2500 g) of 87% and 60% respectively.

Methods

Reliability of the tool used by community volunteers to identify newborns with short feet was tested. Between July-December 2010 a researcher accompanied volunteers to the homes of babies younger than seven days and conducted paired measures of newborn foot length using the counselling card tool and using a plastic ruler. Intra-method reliability of foot length measures was assessed using kappa scores, and differences between measurers were analysed using Bland and Altman plots.

Results

142 paired measures were conducted. The kappa statistic for the foot length tool to classify newborns as having small feet indicated that it was moderately reliable when applied by volunteers, with a kappa score of 0.53 (95% confidence interval 0.40 – 0.66) . Examination of differences revealed that community volunteers systematically underestimated the length of newborn feet compared to the researcher (mean difference −0.26 cm (95% confidence interval −0.31—0.22), thus overestimating the number of newborns needing extra care.

Conclusions

The newborn foot length tool used by community volunteers to identify small babies born at home was moderately reliable in southern Tanzania where a large number of births occur at home and scales are not available. Newborn foot length is not the best anthropometric proxy for birthweight but was simple to implement at home in the first days of life when the risk of newborn death is highest.

Maternal and perinatal health research priorities beyond 2015: an international survey and prioritization exercise

Background

Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the 2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required.

Methods

We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international stakeholders constituting a large reference group, and consolidated into a final list of research questions by a technical working group. Questions on this list were then scored by the reference working group according to five independent and equally weighted criteria. Normalized research priority scores (NRPS) were calculated, and research priority questions were ranked accordingly.

Results

A list of 190 priority research questions for improving maternal and perinatal health was scored by 140 stakeholders. Most priority research questions (89%) were concerned with the evaluation of implementation and delivery of existing interventions, with research subthemes frequently concerned with training and/or awareness interventions (11%), and access to interventions and/or services (14%). Twenty-one questions (11%) involved the discovery of new interventions or technologies.

Conclusions

Key research priorities in maternal and perinatal health were identified. The resulting ranked list of research questions provides a valuable resource for health research investors, researchers and other stakeholders. We are hopeful that this exercise will inform the post-2015 Development Agenda and assist donors, research-policy decision makers and researchers to invest in research that will ultimately make the most significant difference in the lives of mothers and babies.

Implementing facility-based kangaroo mother care services: lessons from a multi-country study in Africa

BACKGROUND

Some countries have undertaken programs that included scaling up kangaroo mother care. The aim of this study was to systematically evaluate the implementation status of facility-based kangaroo mother care services in four African countries: Malawi, Mali, Rwanda and Uganda.

METHODS

A cross-sectional, mixed-method research design was used. Stakeholders provided background information at national meetings and in individual interviews. Facilities were assessed by means of a standardized tool previously applied in other settings, employing semi-structured key-informant interviews and observations in 39 health care facilities in the four countries. Each facility received a score out of a total of 30 according to six stages of implementation progress.

RESULTS

Across the four countries 95 per cent of health facilities assessed demonstrated some evidence of kangaroo mother care practice. Institutions that fared better had a longer history of kangaroo mother care implementation or had been developed as centres of excellence or had strong leaders championing the implementation process. Variation existed in the quality of implementation between facilities and across countries. Important factors identified in implementation are: training and orientation; supportive supervision; integrating kangaroo mother care into quality improvement; continuity of care; high-level buy in and support for kangaroo mother care implementation; and client-oriented care.

CONCLUSION

The integration of kangaroo mother care into routine newborn care services should be part of all maternal and newborn care initiatives and packages. Engaging ministries of health and other implementing partners from the outset may promote buy in and assist with the mobilization of resources for scaling up kangaroo mother care services. Mechanisms for monitoring these services should be integrated into existing health management information systems.

Neonatal survival in complex humanitarian emergencies: setting an evidence-based research agenda

BACKGROUND

Over 40% of all deaths among children under 5 are neonatal deaths (0-28 days), and this proportion is increasing. In 2012, 2.9 million newborns died, with 99% occurring in low- and middle-income countries. Many of the countries with the highest neonatal mortality rates globally are currently or have recently been affected by complex humanitarian emergencies. Despite the global burden of neonatal morbidity and mortality and risks inherent in complex emergency situations, research investments are not commensurate to burden and little is known about the epidemiology or best practices for neonatal survival in these settings.

METHODS

We used the Child Health and Nutrition Research Initiative (CHNRI) methodology to prioritize research questions on neonatal health in complex humanitarian emergencies. Experts evaluated 35 questions using four criteria (answerability, feasibility, relevance, equity) with three subcomponents per criterion. Using SAS 9.2, a research prioritization score (RPS) and average expert agreement score (AEA) were calculated for each question.

RESULTS

Twenty-eight experts evaluated all 35 questions. RPS ranged from 0.846 to 0.679 and the AEA ranged from 0.667 to 0.411. The top ten research priorities covered a range of issues but generally fell into two categories- epidemiologic and programmatic components of neonatal health. The highest ranked question in this survey was "What strategies are effective in increasing demand for, and use of skilled attendance?"

CONCLUSIONS

In this study, a diverse group of experts used the CHRNI methodology to systematically identify and determine research priorities for neonatal health and survival in complex humanitarian emergencies. The priorities included the need to better understand the magnitude of the disease burden and interventions to improve neonatal health in complex humanitarian emergencies. The findings from this study will provide guidance to researchers and program implementers in neonatal and complex humanitarian fields to engage on the research priorities needed to save lives most at risk.

Born too soon: accelerating actions for prevention and care of 15 million newborns born too soon

Preterm birth complication is the leading cause of neonatal death resulting in over one million deaths each year of the 15 million babies born preterm. To accelerate change, we provide an overview of the comprehensive strategy required, the tools available for context-specifi c health system implementation now, and the priorities for research and innovation. There is an urgent need for action on a dual track: (1) through strategic research to advance the prevention of preterm birth and (2) improved implementation and innovation for care of the premature neonate. We highlight evidence-based interventions along the continuum of care, noting gaps in coverage, quality, equity and implications for integration and scale up. Improved metrics are critical for both burden and tracking programmatic change. Linked to the United Nation’s Every Women Every Child strategy, a target was set for 50% reduction in preterm deaths by 2025. Three analyses informed this target: historical change in high income countries, recent progress in best performing countries, and modelling of mortality reduction with high coverage of existing interventions. If universal coverage of selected interventions were to be achieved, then 84% or more than 921,000 preterm neonatal deaths could be prevented annually, with antenatal corticosteroids and Kangaroo Mother Care having the highest impact. Everyone has a role to play in reaching this target including government leaders, professionals, private sector, and of course families who are aff ected the most and whose voices have been critical for change in many of the countries with the most progress.

Balancing investments in existing and emerging approaches to address global health priorities

One of the common themes in contemporary global health is finding an optimal balance between investments in existing and emerging approaches to fight global health priorities. Existing interventions have been proven to be effective, but they usually have limitations. Emerging interventions could potentially bring greater gains at a lower cost, but health gains are usually uncertain and take much more time to achieve. There are no simple solutions on how to balance funding support to these two competing approaches, but some components of successful strategies are becoming increasingly apparent. Transparency over the expected return on investment, style of investment and time horizon can assist rational investment decisions.

Global health research priorities: mobilizing the developing world

The paper focuses on two questions: (i) how to set research priorities in a transparent, systematic, fair and legitimate way?; and (ii) how to mobilize low and middle-income countries to take more ownership in defining their own research policies, rather than merely being passive recipients of international aid for research and development? I propose that the recently developed Child Health and Nutrition Research initiative (CHNRI) methodology is becoming widely accepted as a feasible answer to both those questions. In this paper, I review its numerous applications to date and show how it evolved into a practical and systematic tool that can assist priority setting in health research investments in diverse contexts. The CHNRI methodology also addresses support for different instruments of health research to achieve better balance between fundamental research, translation research and implementation research. The wide application of CHNRI methodology is expected to maximise the potential of health research to reduce disease burden and gradually reduce inequities that exist between support for research on the health problems of the rich and the poor. I believe that this tool will find application within many low and middle-income countries and assist them to pull together their own experts and actively define their priorities for research and development in the coming years.
