Topical applications of chlorhexidine to the umbilical cord for prevention of omphalitis and neonatal mortality in southern Nepal: a community-based, cluster-randomised trial

Prevention of umbilical outpouchings and mortality in pigs: Meloxicam, tying, cutting, and chlorhexidine versus amoxicillin or no treatment? A clinical field trial

BACKGROUND

Umbilical outpouchings (UOs) are common in Danish pigs. Neonatal antibiotics are therefore used with the hope of reducing umbilical infections and subsequently UOs. However, the effect of neonatal antibiotics on preventing UO has been the subject of mixed conclusions, and secondly, treating all animals with antibiotics might exacerbate the development of antimicrobial resistance. This study analysed the effects of different treatments on the prevalence of umbilical outpouchings and mortality from birth to nursery unit. All treatment was on the day of birth. The groups were: a negative control group, an antibiotic group receiving amoxicillin, and an experimental group where the piglets had their umbilical cord disinfected with chlorhexidine, followed by tying and clipping, and lastly, injection with meloxicam. The pigs were examined six weeks after weaning, and all pigs that died during the study were autopsied.

RESULTS

There were 5494 pigs divided across the three groups. There were no statistically significant differences in UO prevalence between the groups: control 3.9%, antibiotic 4.2%, and experimental 4.0% (p = 0.87). The only variable affecting the prevalence of UOs in this study was sex with females being at higher risk. There were no statistically significant differences in mortality between the groups from birth until departure from the nursery unit: control 22.9%, antibiotic 21%, and experimental 21.4% (p = 0.33). The variables affecting mortality were sex, intrauterine growth restriction (IUGR), birth weight, and cross fostering. Males had higher odds of dying, as had piglets recorded with some degree of IUGR. Also, low birth weight increased the odds of dying for all weight quartiles compared to the fourth (the heaviest piglets > 1.6 kg), as well as cross fostering increased the odds ratio of dying.

CONCLUSIONS

This study found no significant differences in the prevalence of UOs and mortality following different treatments at birth. The study showed that the prevalence of UO and mortality was not reduced following the administration of amoxicillin or meloxicam in combination with disinfection and tying of the umbilical cord.

Neonatal mortality risk of vulnerable newborns by fine stratum of gestational age and birthweight for 230 679 live births in nine low- and middle-income countries, 2000-2017

OBJECTIVE

To describe the mortality risks by fine strata of gestational age and birthweight among 230 679 live births in nine low- and middle-income countries (LMICs) from 2000 to 2017.

DESIGN

Descriptive multi-country secondary data analysis.

SETTING

Nine LMICs in sub-Saharan Africa, Southern and Eastern Asia, and Latin America.

POPULATION

Liveborn infants from 15 population-based cohorts.

METHODS

Subnational, population-based studies with high-quality birth outcome data were invited to join the Vulnerable Newborn Measurement Collaboration. All studies included birthweight, gestational age measured by ultrasound or last menstrual period, infant sex and neonatal survival. We defined adequate birthweight as 2500-3999 g (reference category), macrosomia as ≥4000 g, moderate low as 1500-2499 g and very low birthweight as <1500 g. We analysed fine strata classifications of preterm, term and post-term: ≥42+0 , 39+0 -41+6 (reference category), 37+0 -38+6 , 34+0 -36+6 ,34+0 -36+6 ,32+0 -33+6 , 30+0 -31+6 , 28+0 -29+6 and less than 28 weeks.

MAIN OUTCOME MEASURES

Median and interquartile ranges by study for neonatal mortality rates (NMR) and relative risks (RR). We also performed meta-analysis for the relative mortality risks with 95% confidence intervals (CIs) by the fine categories, stratified by regional study setting (sub-Saharan Africa and Southern Asia) and study-level NMR (≤25 versus >25 neonatal deaths per 1000 live births).

RESULTS

We found a dose-response relationship between lower gestational ages and birthweights with increasing neonatal mortality risks. The highest NMR and RR were among preterm babies born at <28 weeks (median NMR 359.2 per 1000 live births; RR 18.0, 95% CI 8.6-37.6) and very low birthweight (462.8 per 1000 live births; RR 43.4, 95% CI 29.5-63.9). We found no statistically significant neonatal mortality risk for macrosomia (RR 1.1, 95% CI 0.6-3.0) but a statistically significant risk for all preterm babies, post-term babies (RR 1.3, 95% CI 1.1-1.5) and babies born at 370 -386  weeks (RR 1.2, 95% CI 1.0-1.4). There were no statistically significant differences by region or underlying neonatal mortality.

CONCLUSIONS

In addition to tracking vulnerable newborn types, monitoring finer categories of birthweight and gestational age will allow for better understanding of the predictors, interventions and health outcomes for vulnerable newborns. It is imperative that all newborns from live births and stillbirths have an accurate recorded weight and gestational age to track maternal and neonatal health and optimise prevention and care of vulnerable newborns.

Quantitative assessment of umbilical cord care practices amongst mothers in Jos, Plateau State, Nigeria

Introduction

A newly cut neonatal umbilical stump is a potential portal of pathogen entry leading to omphalitis. Neonatal sepsis can complicate omphalitis, but good cord care practices can reduce this risk.

Objective

The objective of this study was to assess umbilical cord care practices in tertiary-, secondary- and primary-level healthcare facilities in Jos, Nigeria.

Methods

A multi-centre, cross-sectional study of 284 mothers of infants aged 3-6 weeks old attending immunisation clinics in the three-level healthcare facilities using multistage sampling technique between April and September 2019. Data were analysed using SPSS version 23.0. Pearson's Chi-squared test was used to compare categorical variables. Adjusted odds ratios (AORs) and 95% confidence interval (CI) were used as point and interval estimates, respectively. P < 0.05 was adjudged to be statistically significant.

Results

The mean age of the mothers and infants was 25 ± 6 years and 5 ± 1 week, respectively. Only 2.2% of mothers used chlorhexidine (CHX) gel for cord care. Mothers showed good knowledge but poor practice of cord care. A significant positive relationship was observed between quality of cord care practices and level of healthcare facility (χ2 = 15.213; df = 2; P < 0.001). Good cord care practices were predicted by mothers' age 30-46 (AOR = 3.6; CI: 1.4-9.1) and good knowledge of cord care (AOR = 4.7; 95% CI: 2.2-9.9).

Conclusions

The study has highlighted the good knowledge but poor practices of cord care by mothers and the need to scale up the uptake of CHX gel in Jos. Mother's age and good knowledge of cord care are predictors of good cord care practices.

The impact of umbilical cord care education given to Primiparous mothers on cord separation time: A randomized controlled study

PURPOSE

This study aims to determine the impact of umbilical cord care education given to primiparous mothers on cord separation time.

DESIGN AND METHODS

This randomized controlled trial was conducted according to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. The mothers constituting the research sample were divided into two groups, the control group and the education group, and cord care and cord separation times were measured.

RESULTS

The mean age of the mothers was 28.72 ± 4.86 years (min. 20 years, max. 40 years). There was no difference in age, gestational week of the baby, birth weight of the baby, gender of the baby and mode of delivery of the mother between the mothers in the control and education groups. While the cord separation time was 10.97 ± 0.320 days in the babies in the control group, it was 6.60 ± 0.177 days in the babies in the education group. A statistically significant difference was found between the duration of cord separation of the babies in the control and education groups.

CONCLUSIONS

This study showed that giving umbilical cord care education to primiparous mothers reduces umbilical cord separation time.

PRACTICE IMPLICATIONS

It is recommended that pediatric nurses provide education on umbilical cord care and the goals and methods of application of care practices, especially to primiparous mothers.

CLINICAL REGISTRATION

This study was registered at the U.S. National Library of Medicine Clinical Trials (code: NCT05573737).

Neonatal mortality risk of vulnerable newborns: A descriptive analysis of subnational, population-based birth cohorts for 238 203 live births in low- and middle-income settings from 2000 to 2017

OBJECTIVE

We aimed to understand the mortality risks of vulnerable newborns (defined as preterm and/or born weighing smaller or larger compared to a standard population), in low- and middle-income countries (LMICs).

DESIGN

Descriptive multi-country, secondary analysis of individual-level study data of babies born since 2000.

SETTING

Sixteen subnational, population-based studies from nine LMICs in sub-Saharan Africa, Southern and Eastern Asia, and Latin America.

POPULATION

Live birth neonates.

METHODS

We categorically defined five vulnerable newborn types based on size (large- or appropriate- or small-for-gestational age [LGA, AGA, SGA]), and term (T) and preterm (PT): T + LGA, T + SGA, PT + LGA, PT + AGA, and PT + SGA, with T + AGA (reference). A 10-type definition included low birthweight (LBW) and non-LBW, and a four-type definition collapsed AGA/LGA into one category. We performed imputation for missing birthweights in 13 of the studies.

MAIN OUTCOME MEASURES

Median and interquartile ranges by study for the prevalence, mortality rates and relative mortality risks for the four, six and ten type classification.

RESULTS

There were 238 203 live births with known neonatal status. Four of the six types had higher mortality risk: T + SGA (median relative risk [RR] 2.6, interquartile range [IQR] 2.0-2.9), PT + LGA (median RR 7.3, IQR 2.3-10.4), PT + AGA (median RR 6.0, IQR 4.4-13.2) and PT + SGA (median RR 10.4, IQR 8.6-13.9). T + SGA, PT + LGA and PT + AGA babies who were LBW, had higher risk compared with non-LBW babies.

CONCLUSIONS

Small and/or preterm babies in LIMCs have a considerably increased mortality risk compared with babies born at term and larger. This classification system may advance the understanding of the social determinants and biomedical risk factors along with improved treatment that is critical for newborn health.

Umbilical Cord Stump Infections in Central Uganda: Incidence, Bacteriological Profile, and Risk Factors

Umbilical cord stump infection (omphalitis) is a risk factor for neonatal sepsis and death. We assessed the incidence of omphalitis, described the bacteriological and antibiotic-resistance profile of potentially pathogenic bacteria isolated from the umbilical cord stump of omphalitis cases, and evaluated whether bacteria present in the birth canal during birth predicted omphalitis. We enrolled 769 neonates at birth at three primary healthcare facilities and followed them for 28 days with scheduled visits on days 3, 7, 14, and 28. Cox regression models were used to estimate the rates of omphalitis associated with potential risk factors. Sixty-five (8.5%) neonates developed omphalitis, with an estimated incidence of 0.095 cases per 28 child-days (95% CI 0.073, 0.12). Potentially pathogenic bacteria were isolated from the cord stump area of 41 (63.1%) of the 65 neonates with omphalitis, and the most commonly isolated species were Escherichia coli (n = 18), Klebsiella pneumoniae (n = 10), Citrobacter freundii (n = 5), and Enterobacter spp. (n = 4). The Enterobacteriaceace isolates were resistant to gentamicin (10.5%, 4/38), ampicillin (86.8%, 33/38), and ceftriaxone (13.2%, 5/38). Delayed initiation of breastfeeding was associated with an increased risk of omphalitis (aHR 3.1; 95% CI 1.3, 7.3); however, vaginal colonization with potentially pathogenic bacteria did not predict omphalitis.

Increasing access to essential medicines through partnership: experience in developing and delivering chlorhexidine gel for newborn cord care

Sustainable access to essential medicines in low-income and middle-income countries requires innovative cross-sectoral collaboration throughout the lifecycle of a medicine. Partnerships are essential to address the systemic challenges of global health and health inequity. Pharmaceutical companies, funders, governments, international non-governmental organisations (I-NGOs) and other key stakeholders can leverage, through effective partnership working, their unique expertise to help drive innovation and share learnings and risks. Here, we reflect on one approach taken in the development and supply of chlorhexidine digluconate 7.1% w/w gel (equivalent to 4% w/w chlorhexidine) for neonatal cord care. We describe and analyse the steps taken by GSK to increase access to chlorhexidine gel, including partnering with the I-NGO Save the Children in Western Kenya. Learning points gained along the journey are shared, together with subsequent steps taken to increase access, with the aim of making recommendations that may be applicable to similar enterprises in the future.

Chlorhexidine cord care after a national scale-up as a newborn survival strategy: A survey in four regions of Ethiopia

Introduction

Chlorhexidine cord care is an effective intervention to reduce neonatal infection and death in resource constrained settings. The Federal Ministry of Health of Ethiopia adopted chlorhexidine cord care in 2015, with national scale-up in 2017. However, there is lack of evidence on the provision of this important intervention in Ethiopia. In this paper, we report on the coverage and determinants of chlorhexidine cord care for newborns in Ethiopia.

Methods

A standardized Nutrition International Monitoring System (NIMS) survey was conducted from January 01 to Feb 13, 2020 in four regions of Ethiopia (Tigray, Amhara, Oromia, and Southern Nations, Nationalities and Peoples Region [SNNPR]) on sample of 1020 women 0–11 months postpartum selected through a multistage cluster sampling approach. Data were collected using interviewer-administered questionnaires in the local languages through home-to-home visit. Accounting for the sampling design of the study, we analyzed the data using complex data analysis approach. Complex sample multivariable logistic regression was used to identify the determinants of chlorhexidine cord care practice.

Results

Overall, chlorhexidine was reportedly applied to the umbilical cord at some point postpartum among 46.1% (95% confidence interval [CI]: 41.1%– 51.2%) of all newborns. Chlorhexidine cord care started within 24 hours after birth for 34.4% (95% CI: 29.5%– 39.6%) of newborns, though this varied widely across regions: from Oromia (24.4%) to Tigray (60.0%). Among the newborns who received chlorhexidine cord care, 48.3% received it for the recommended seven days or more. Further, neonates whose birth was assisted by skilled birth attendants had more than ten times higher odds of receiving chlorhexidine cord care, relative to those born without a skilled attendant (adjusted odds ratio [AOR]: 10.36, 95% CI: 3.73–28.75). Besides, neonates born to mothers with knowledge of the benefit of chlorhexidine cord care had significantly higher odds of receiving chlorhexidine cord care relative to newborns born to mothers who did not have knowledge of the benefit of chlorhexidine cord care (AOR: 39.03, 95% CI: 21.45–71.04).

Conclusion

A low proportion of newborns receive chlorhexidine cord care in Ethiopia. The practice of chlorhexidine cord care varies widely across regions and is limited mostly to births attended by skilled birth attendants. Efforts must continue to ensure women can reach skilled care at delivery, and to ensure adequate care for newborns who do not yet access skilled delivery.

Development of an imputation model to recalibrate birth weights measured in the early neonatal period to time at delivery and assessment of its impact on size-for-gestational age and low birthweight prevalence estimates: a secondary analysis of a pregnancy cohort in rural Nepal

OBJECTIVES

In low-income countries, birth weights for home deliveries are often measured at the nadir when babies may lose up of 10% of their birth weight, biasing estimates of small-for-gestational age (SGA) and low birth weight (LBW). We aimed to develop an imputation model that predicts the 'true' birth weight at time of delivery.

DESIGN

We developed and applied a model that recalibrates weights measured in the early neonatal period to time=0 at delivery and uses those recalibrated birth weights to impute missing birth weights.

SETTING

This is a secondary analysis of pregnancy cohort data from two studies in Sarlahi district, Nepal.

PARTICIPANTS

The participants are 457 babies with daily weights measured in the first 10 days of life from a subsample of a larger clinical trial on chlorhexidine (CHX) neonatal skin cleansing and 31 116 babies followed through the neonatal period to test the impact of neonatal massage oil type (Nepal Oil Massage Study (NOMS)).

OUTCOME MEASURES

We developed an empirical Bayes model of early neonatal weight change using CHX trial longitudinal data and applied it to the NOMS dataset to recalibrate and then impute birth weight at delivery. The outcomes are size-for-gestational age and LBW.

RESULTS

When using the imputed birth weights, the proportion of SGA is reduced from 49% (95% CI: 48% to 49%) to 44% (95% CI: 43% to 44%). Low birth weight is reduced from 30% (95% CI: 30% to 31%) to 27% (95% CI: 26% to 27%). The proportion of babies born large-for-gestational age increased from 4% (95% CI: 4% to 4%) to 5% (95% CI: 5% to 5%).

CONCLUSIONS

Using weights measured around the nadir overestimates the prevalence of SGA and LBW. Studies in low-income settings with high levels of home births should consider a similar recalibration and imputation model to generate more accurate population estimates of small and vulnerable newborns.

Bayesian spatial analysis of factors influencing neonatal mortality and its geographic variation in Ethiopia

Background

Ethiopia is a Sub-Saharan country with very high neonatal mortality rates, varying across its regions. The rate of neonatal mortality reduction in Ethiopia is slow, and Ethiopia may not meet the third United Nations sustainable development target by 2030. This study aimed to investigate the spatial variations and contributing factors for neonatal mortality rates in Ethiopia.

Methods

We analysed data from the 2016 Ethiopian Demographic and Health Survey (EDHS), which used a two-stage cluster sampling technique with a census enumeration area as primary and households as secondary sampling units. A Bayesian spatial logistic regression model using the Stochastic Partial Differential Equation (SPDE) method was fitted accounting for socio-economic, health service-related and geographic factors.

Results

Higher neonatal mortality rates were observed in eastern, northeastern and southeastern Ethiopia, and the Somali region had higher risks of neonatal mortality. Neonates from frequently drought-affected areas had a higher mortality risk than less drought-affected areas. Application of traditional substances on the cord increased the risk of neonatal mortality (Adjusted Odds Ratio (AOR) = 2.07, 95% Credible Interval (CrI): 1.12 to 4.30) and getting health facility delivery services had a lower odds of neonatal mortality (AOR = 0.60, 95% CrI: 0.37, 0.98).

Conclusions

Residing in drought-affected areas, applying traditional substances on the umbilical cord and not delivering at health facilities were associated with a higher risk of neonatal mortality. Policy-makers and resource administrators at different administrative levels could leverage the findings to prioritise and target areas identified with higher neonatal mortality rates.

Umbilical Cord Care Practices and Associated Factor Among Mothers of Neonates Visiting Mizan-Tepi University Teaching Hospital Southwest Ethiopia 2021

Background

Due to unsanitary cord care practices, cord infections are more common and prevalent in developing countries. In settings where mortality is low, dry and clean cord care is recommended for newborns delivered in health facilities or at home. Cord care practices would directly contribute to infection in newborns, accounting for a large proportion of millions of annual neonatal deaths. This study aimed to assess the cord care practices of mothers and to identify areas for intervention.

Methods

An institution-based cross-sectional study was conducted among mothers of neonates who gave birth in the last six months. Systematic random sampling technique was employed to include women who visited pediatric OPD and immunization clinics. Epi data version 3.1 was used to enter the data and then exported to SPSS version 26 for analysis. The association between the outcome and independent variables was examined using binary logistic regression. The strength of the association was measured using odds ratio (OR), 95% confidence intervals (CI) and p-value. Statistical significance was declared at a p-value <0.05.

Results

Four hundred twenty-two mothers were participated in the study. More than half (59.2%) of the respondents had good cord care practices, while nearly half (45.3%) mothers added nothing to the cord. Factors significantly associated with good cord care practices were educational status (AOR = 4.7; 95% CI = 1.34, 7.59), ANC follow-up (AOR = 3.58; 95% CI = 1.24, 10.32), initiation of breastfeeding (AOR = 1.74; 95% CI = 1.10, 2.77), and apply anything to the cord (AOR = 3.08; 95% CI = 1.92, 4.95).

Conclusion

The proportion of mothers with good cord care practices was inadequate. For such a high cause of neonatal death, prevention should be the priority intervention, and improving its implementation requires further effort.

Risk of infection in neonates born in accidental out-of-hospital deliveries

Accidental out-of-hospital deliveries (OHDs) are known to have a higher incidence of maternal and neonatal complications. However, neonatal infection related to OHDs has not been studied. The aim of this study was to determine the infection risk of OHDs. This retrospective cohort study enrolled neonates admitted at a children’s hospital in an urban setting from January 2004 to December 2017. Accidental OHDs were compared with in-hospital births, and neonatal infection was assessed. This study also investigated both maternal and neonatal risk factors associated with OHDs. A cohort of 158 OHD neonates was enrolled, of whom 29 (23.2%) were preterm. Prematurity and low birth weight were significantly associated with OHD. Eight neonates in the OHD cohort had a documented infection within the first 72 hours of life, which was 11-fold higher than infections documented for the in-hospital births. Multivariate analysis identified low birth weight as the only factor independently associated with increased risk of infection in OHD neonates. Several specific characteristics of mothers with OHDs were identified. Forty-nine (31%) OHD mothers lacked antenatal care, and 10 (6.3%) were unaware of their pregnancies. The OHD group comprised of more teenage mothers compared to the in-hospital deliveries category. Neonatal infection was more prevalent among OHDs than for in-hospital deliveries, and the infection rate was associated with low birth weight. Hospitalization for further care and observation is suggested for the OHD neonates. Social support should be provided for populations with an increased risk of OHD, such as teenage mothers.

Cost and consequences of using 7.1 % chlorhexidine gel for newborn umbilical cord care in Kenya

Background

Omphalitis is an important contributor to neonatal mortality in Kenya. Chlorhexidine digluconate 7.1 % w/w (CHX; equivalent to 4 % w/w chlorhexidine) was identified as a life-saving commodity for newborn cord care by the United Nations and is included on World Health Organization and Kenyan Essential Medicines Lists. This pilot study assessed the potential resource savings and breakeven price of implementing CHX for neonatal umbilical cord care versus dry cord care (DCC) in Kenya.

Methods

We employed a cost-consequence model in a Kenyan birth cohort. Firstly, the number of omphalitis cases and cases avoided by healthcare sector were estimated. Incidence rates and treatment effect inputs were calculated from a Cochrane meta-analysis of randomised clinical trials (RCTs) (base case) and 2 other RCTs. Economic outcomes associated with omphalitis cases avoided were determined, including direct, indirect and total cost of care associated with omphalitis, resource use (outpatient visits and bed days) and societal impact (caregiver workdays lost). Costs and other inputs were sourced from literature and supplemented by expert clinical opinion/informed inputs, making necessary assumptions.

Results

The model estimated that, over 1 year, ~ 23,000 omphalitis cases per 500,000 births could be avoided through CHX application versus DCC, circumventing ~ 13,000 outpatient visits, ~ 43,000 bed days and preserving ~ 114,000 workdays. CHX was associated with annual direct cost savings of ~ 590,000 US dollars (USD) versus DCC (not including drug-acquisition cost), increasing to ~ 2.5 million USD after including indirect costs (productivity, notional salary loss). The most-influential model parameter was relative risk of omphalitis with CHX versus DCC. Breakeven analysis identified a budget-neutral price for CHX use of 1.18 USD/course when accounting for direct cost savings only, and 5.43 USD/course when including indirect cost savings. The estimated breakeven price was robust to parameter input changes. DCC does not necessarily represent standard of care in Kenya; other, potentially harmful, approaches may be used, meaning cost savings may be understated.

Conclusions

Estimated healthcare cost savings and potential health benefits provide compelling evidence to implement CHX for umbilical cord care in Kenya. We encourage comprehensive data collection to make future models and estimates of impacts of upscaling CHX use more robust.

Improving global maternal and newborn survival via innovation: Stakeholder perspectives on the Saving Lives at Birth Grand Challenge

The Saving Lives at Birth (SL@B) funding partners joined in 2011 to source, support, and scale maternal and newborn health (MNH) innovations to improve maternal and newborn survival by focusing on the 24 hours around the time of birth. A multi-methods, retrospective portfolio evaluation was conducted to determine SL@B's impact. Forty semi-structured, key informant interviews (KIIs) were conducted with experts in global MNH based in low- and middle-income and in high-income countries to assess the SL@B program. KIIs were conducted with global MNH technical experts, innovators, government officials in low- and middle-income countries, donors, private investors, and implementing partners to include the full spectrum of voices involved in identifying and scaling innovations. Data were analyzed using thematic analysis. Stakeholders believe the SL@B program has been successful in changing the way maternal and newborn health programs are delivered with a focus on doing things differently through innovation. The open approach to sourcing innovation was seen as positive to the extent that it brought more interdisciplinary stakeholders to think about the problem of maternal and newborn survival. However, a demand-driven approach that aims to source innovations that address MNH priority needs and takes into account the needs of end users (e.g. individuals and governments) was suggested as a strategy for ensuring that more innovations go to scale.

The role and challenges of cluster randomised trials for global health

Evaluating whether an intervention works when trialled in groups of individuals can pose complex challenges for clinical research. Cluster randomised controlled trials involve the random allocation of groups or clusters of individuals to receive an intervention, and they are commonly used in global health research. In this paper, we describe the potential reasons for the increasing popularity of cluster trials in low-income and middle-income countries. We also draw on key areas of global health research for an assessment of common trial planning practices, and we address their methodological shortcomings and pitfalls. Lastly, we discuss alternative approaches for population-level intervention trials that could be useful for research undertaken in low-income and middle-income countries for situations in which the use of cluster randomisation might not be appropriate.

Chlorhexidine for facility-based umbilical cord care: EN-BIRTH multi-country validation study

BACKGROUND

Umbilical cord hygiene prevents sepsis, a leading cause of neonatal mortality. The World Health Organization recommends 7.1% chlorhexidine digluconate (CHX) application to the umbilicus after home birth in high mortality contexts. In Bangladesh and Nepal, national policies recommend CHX use for all facility births. Population-based household surveys include optional questions on CHX use, but indicator validation studies are lacking. The Every Newborn Birth Indicators Research Tracking in Hospitals (EN-BIRTH) was an observational study assessing measurement validity for maternal and newborn indicators. This paper reports results regarding CHX.

METHODS

The EN-BIRTH study (July 2017-July 2018) included three public hospitals in Bangladesh and Nepal where CHX cord application is routine. Clinical-observers collected tablet-based, time-stamped data regarding cord care during admission to labour and delivery wards as the gold standard to assess accuracy of women's report at exit survey, and of routine-register data. We calculated validity ratios and individual-level validation metrics; analysed coverage, quality and measurement gaps. We conducted qualitative interviews to assess barriers and enablers to routine register-recording.

RESULTS

Umbilical cord care was observed for 12,379 live births. Observer-assessed CHX coverage was very high at 89.3-99.4% in all 3 hospitals, although slightly lower after caesarean births in Azimpur (86.8%), Bangladesh. Exit survey-reported coverage (0.4-45.9%) underestimated the observed coverage with substantial "don't know" responses (55.5-79.4%). Survey-reported validity ratios were all poor (0.01 to 0.38). Register-recorded coverage in the specific column in Bangladesh was underestimated by 0.2% in Kushtia but overestimated by 9.0% in Azimpur. Register-recorded validity ratios were good (0.9 to 1.1) in Bangladesh, and poor (0.8) in Nepal. The non-specific register column in Pokhara, Nepal substantially underestimated coverage (20.7%).

CONCLUSIONS

Exit survey-report highly underestimated observed CHX coverage in all three hospitals. Routine register-recorded coverage was closer to observer-assessed coverage than survey reports in all hospitals, including for caesarean births, and was more accurately captured in hospitals with a specific register column. Inclusion of CHX cord care into registers, and tallied into health management information system platforms, is justified in countries with national policies for facility-based use, but requires implementation research to assess register design and data flow within health information systems.

The effect of umbilical cord cleansing with chlorhexidine gel on neonatal mortality among the community births in South Sudan: a quasi-experimental study

Introduction

the use of chlorhexidine antiseptic gel for umbilical cord care in unhygienic settings has been shown to reduce infection and neonatal mortality in Asia, leading to the revision of WHO guidelines. However, few studies exist in the African context and none have been undertaken in conflict-affected settings. We aimed to assess the effectiveness of applying chlorhexidine gel to the umbilical cord stump on cord sepsis and neonatal mortality rates in the Republic of South Sudan.

Methods

our pre/post quasi-experimental study recruited 3,143 pregnant women from six rural communities in Jubek County, South Sudan: 1,825 women in the treatment group and 1,318 women in the control group. Neonates in the treatment group had chlorhexidine applied to the umbilical cord stump within 24 hours of birth and daily for seven days. No chlorhexidine gel was applied in the control group, instead they were encouraged to practice dry cord care. Data was collected at enrolment and at each antenatal visit at 3, 7, 14 and 28 days. Our primary outcomes of interest were incidence of neonatal umbilical cord sepsis and neonatal mortality, which were analyzed on an intention-to-treat basis. The study is registered with Pan African Clinical Trial Registry, Number PACTR201808694484456.

Results

the neonatal cord infection rate among the treatment group was 17.0%, compared to 38.9% in the control group (P<0.05), which was statistically significant. Neonatal mortality was least in the intervention (1.3%) and highest in the control (13.3%) group, which was also statistically significant.

Conclusion

our evidence showed that chlorhexidine gel application contributed to the reduction of cord sepsis and neonatal mortality in conflict-affected South Sudan where the majority of births happen at home in unsanitary conditions. Chlorhexidine gel should be added to the essential medicines list in South Sudan and a costed plan for scale-up of chlorhexidine gel application should be developed by the Ministry of Health.

Using propensity scores to estimate the effectiveness of maternal and newborn interventions to reduce neonatal mortality in Nigeria

Background

Nigeria is the largest country in sub-Saharan Africa, with one of the highest neonatal mortality rates and the second highest number of neonatal deaths in the world. There is broad international consensus on which interventions can most effectively reduce neonatal mortality, however, there is little direct evidence on what interventions are effective in the Nigerian setting.

Methods

We used the 2013 Nigeria Demographic and Health Survey (NDHS) and the follow-up 2014 Verbal and Social Autopsy study of neonatal deaths to estimate the association between neonatal survival and mothers’ and neonates’ receipt of 18 resources and interventions along the continuum of care with information available in the NDHS. We formed propensity scores to predict the probability of receiving the intervention or resource and then weighted the observations by the inverse of the propensity score to estimate the association with mortality. We examined all-cause mortality as well as mortality due to infectious causes and intrapartum related events.

Results

Among 19,685 livebirths and 538 neonatal deaths, we achieved adequate balance for population characteristics and maternal and neonatal health care received for 10 of 18 resources and interventions, although inference for most antenatal interventions was not possible. Of ten resources and interventions that met our criteria for balance of potential confounders, only early breastfeeding was related to decreased all-cause neonatal mortality (relative risk 0.42, 95% CI 0.32–0.52, p <  0.001). Maternal decision making and postnatal health care reduced mortality due to infectious causes, with relative risks of 0.29 (95% CI 0.09–0.88; 0.030) and 0.46 (0.22–0.95; 0.037), respectively. Early breastfeeding and delayed bathing were related to decreased mortality due to intrapartum events, although these are not likely to be causal associations.

Conclusion

Access to immediate postnatal care and women’s autonomous decision-making have been among the most effective interventions for reducing neonatal mortality in Nigeria. As neonatal mortality increases relative to overall child mortality, accessible interventions are necessary to make further progress for neonatal survival in Nigeria and other low resource settings.

Preventing Bloodstream Infections and Death in Zambian Neonates: Impact of a Low-cost Infection Control Bundle

BACKGROUND

Sepsis is a leading cause of neonatal mortality in low-resource settings. As facility-based births become more common, the proportion of neonatal deaths due to hospital-onset sepsis has increased.

METHODS

We conducted a prospective cohort study in a neonatal intensive care unit in Zambia where we implemented a multifaceted infection prevention and control (IPC) bundle consisting of IPC training, text message reminders, alcohol hand rub, enhanced environmental cleaning, and weekly bathing of babies ≥1.5 kg with 2% chlorhexidine gluconate. Hospital-associated sepsis, bloodstream infection (BSI), and mortality (>3 days after admission) outcome data were collected for 6 months prior to and 11 months after bundle implementation.

RESULTS

Most enrolled neonates had a birth weight ≥1.5 kg (2131/2669 [79.8%]). Hospital-associated mortality was lower during the intervention than baseline period (18.0% vs 23.6%, respectively). Total mortality was lower in the intervention than prior periods. Half of enrolled neonates (50.4%) had suspected sepsis; 40.8% of cultures were positive. Most positive blood cultures yielded a pathogen (409/549 [74.5%]), predominantly Klebsiella pneumoniae (289/409 [70.1%]). The monthly rate and incidence density rate of suspected sepsis were lower in the intervention period for all birth weight categories, except babies weighing <1.0 kg. The rate of BSI with pathogen was also lower in the intervention than baseline period.

CONCLUSIONS

A simple IPC bundle can reduce sepsis and death in neonates hospitalized in high-risk, low-resource settings. Further research is needed to validate these findings in similar settings and to identify optimal implementation strategies for improvement and sustainability.

Assessment of knowledge and quality of essential newborn care practices in La Dade Kotopon Municipality, Ghana

Majority of neonatal deaths in developing countries have been associated with inappropriate or poorly practiced newborn care, specifically safe cord care, optimal thermal care and early initiation and practice of exclusive breastfeeding. There is limited information about the quality of these essential newborn care practices in Accra, Ghana. The main objective of this study was to assess the knowledge about and quality of essential newborn care practices (ENC) and determine related factors in La Dade Kotopon Municipal Assembly, Accra, Ghana. A questionnaire-based, cross-sectional study was conducted among 423 mothers and caregivers in two hospitals to assess safe cord care, optimal thermal care and exclusive breastfeeding. Knowledge was assessed using eight statements regarding ENC and categorized as 'Adequate knowledge' and 'Inadequate knowledge' using a composite score. Practices were similarly categorized as 'Good' and 'Poor' ENC. Data were exported from Microsoft Excel into STATA version 15 for statistical analysis. Descriptive statistics were generated and inferential analysis was done using chi-square test and logistic regression to determine factors associated with good ENC at 95% confidence level. All respondents sampled participated in the study. A total of 263 (62%) respondents had adequate knowledge and 308 (73%) respondents practiced appropriate newborn care ('Good' ENC). The likelihood of appropriate newborn care practices was lower among mothers/caregivers who were unemployed (AOR = 0.13, 95% CI: 0.09-0.26), who had a home delivery (AOR = 0.17, 95% CI: 0.11-0.69) and made their first antenatal visit in the third trimester (AOR = 0.02, 95% CI: 0.01-0.35) compared to their counterparts. Knowledge of ENC was not associated with practice in this study. Appropriate newborn care practices were relatively high among the respondents. Improving sources of livelihood and targeted education to encourage early antenatal visits and facility-based births might improve newborn care where it is inadequate.

Impact of chlorhexidine baths on suspected sepsis and bloodstream infections in hospitalized neonates in Zambia

INTRODUCTION

Sepsis is the leading cause of infectious morbidity and mortality among hospitalized neonates. In high-resource pediatric and adult intensive care units, use of aqueous chlorhexidine (CHG) solution has been associated with reduced risk of bloodstream infections (BSI).

OBJECTIVES

To assess the impact of bathing of neonates with 2% CHG on BSI, suspected sepsis, and mortality in a low-income country neonatal care unit.

METHODS

We conducted a secondary analysis of data from the Sepsis Prevention in Neonates in Zambia (SPINZ) study, a prospective observational cohort study performed at a large public referral hospital in Lusaka, Zambia. The SPINZ study assessed the impact of an infection control bundle (consisting of alcohol hand rub, SMS hygiene reminders, enhanced environmental cleaning, and CHG baths for babies ≥1.5 kg) on sepsis, BSI, and all-cause mortality. Episodic shortages in study staffing resulted in some enrolled babies not receiving a CHG bath. Using Longitudinal Targeted Maximum Likelihood Estimation and Cox proportional hazards regression to adjust for observed confounding, we estimated the causal effect of receiving a CHG bath within the first 3 days of life on suspected sepsis, BSI, and death among inborn babies enrolled during the study implementation and intervention phases.

RESULTS

The majority of inborn, enrolled babies ≥1.5 kg received a CHG bath within 3 days of NICU admission (864 of 1233, 70%). We found that CHG bathing reduced the hazard rate of BSI among inborn babies ≥1.5 kg by a factor of 0.58 (p = 0.10, 95% CI: 0.31, 1.11), corresponding to an absolute risk reduction of 9.6 percentage points within a week of admission (p = 0.002, 95% CI: 3.4-15.7 percentage points). We did not find a statistically significant effect of CHG bathing on culture-negative sepsis (p = 0.54) or death (p = 0.85).

CONCLUSION

In our single center study, CHG bathing at admission was associated with a reduced risk of BSI due to a pathogenic organism after adjusting for potential confounding. Our results suggest that CHG may be an effective intervention for preventing neonatal sepsis in high-risk, low-income country settings.

Characteristics of Early Newborn Care: A Descriptive Analysis of Recent Births in Nigeria

BACKGROUND OR OBJECTIVES

The neonatal period, the first 28 days of life, is the most critical period for child survival. In 2017, 214,000 children in Nigeria died during the neonatal period. Newborn care practices play a key role in preventing these deaths. The aim of this study was to examine the association between delivery location and early newborn care in Nigeria.

METHODS

Data from the 2013 Nigeria Demographic and Health Survey were analyzed. The main exposure variable was delivery location (home, public hospital, public health center/clinic and private hospital/clinic). The outcomes were early initiation of breastfeeding, breastfeeding support, and cord examination. We used multivariate logistic regression to estimate the odds of newborn care.

RESULTS

We observed that the prevalence of all three outcome indicators was low. After adjusting for confounders, birth in public health facilities, compared to home birth, was associated with early initiation of breastfeeding (public hospitals: OR 1.62, 95% CI: 1.29-2.03; public health centers/clinics OR: 1.28, 95% CI: 1.02-1.61). Breastfeeding support and cord examination were each associated with birth in public hospitals only compared to home birth (OR 1.41, 95% CI: 1.09-1.81 and OR 1.41, 95% CI: 1.11-1.79, respectively).

CONCLUSION AND GLOBAL HEALTH IMPLICATIONS

Early newborn care in Nigeria was suboptimal and the quality of this care varied across delivery locations and birth attendants. Public hospitals had the most favorable newborn care outcomes. Policies and programs to enhance the quality of facility-based early newborn care and promote community-based newborn care could improve neonatal outcomes and reduce overall child mortality in resource-challenged settings.

Factors associated with newborn care knowledge and practices in the upper Himalayas

Background

Globally, neonatal deaths remain a major public health challenge and account for the majority of deaths occurring among children under five years of age. Despite Nepal’s significant achievements in meeting the maternal and child health targets of the Millennium Development Goals, an estimated 23,000 Nepalese children under five years die every year, with three out of five babies dying within the first 28 days of life. This study therefore aimed to examine the level of knowledge and practices of newborn care among Nepalese mothers in the upper Himalayas and the factors associated with these.

Materials and methods

A community based cross-sectional study was conducted among 302 randomly selected mothers with children under two years of age in Tripurasundari Municipality of Dolpa district, an upper Himalayan region of Nepal. Mothers were interviewed using semi-structured questionnaires. Mean score for knowledge and Bloom’s criteria for practice were considered to categorize newborn care knowledge and practices. Multivariate logistic regression was used to identify factors associated with the newborn care knowledge and practices.

Results

In this study, 147 (48.7%) of the mothers were found to have inadequate knowledge of newborn care, while 102 (33.8%) mothers had reported unsatisfactory newborn care practices. Mothers with at least secondary level of formal education were more likely to possess adequate newborn care knowledge compared to mothers who never attended school (AOR 4.93 at 95% CI 1.82–13.33). Mothers whose first pregnancy occurred between the ages of 20–24 years (AOR 3.89 at 95% CI 1.81–8.37) were also more likely to possess adequate newborn care knowledge, compared to mothers with a younger age at first pregnancy. Furthermore, mothers who had completed at least four ANC visits (AOR 2.89 at 95% CI 1.04–7.96), mothers who had completed three PNC visits (AOR 2.79 at 95% CI 1.16–6.72) and mothers who reported that their nearest health facility was less than one hour (30–59 minutes) walking distance (AOR 3.66 at 95% CI 1.43–9.33) had higher odds of having adequate newborn care knowledge. Similarly, mothers whose household monthly income was more than $100 (AOR 4.17 at 95% CI 1.75–9.69), mothers who had completed three PNC visits (AOR 3.27 at 95% CI 1.16–9.20) and mothers with adequate newborn care knowledge (AOR 15.35 at 95% CI 5.82–40.47) were found to be more likely to practice a satisfactory level of newborn care practices in adjusted analysis.

Conclusion

The study revealed high prevalence of inadequate newborn care and knowledge amongst mothers in upper Himalayan dwellings. Approximately one third of all interviewed mothers practiced suboptimal newborn care. The results indicate an urgent need to increase awareness of neonatal services available to mothers and to prioritize investments by local governments in neonatal health services, in order to improve accessibility and quality of care for mothers and newborns.

The Use of Alcohol versus Dry Care for the Umbilical Cord in Newborns: A Systematic Review and Meta-analysis of Randomized and Non-randomized Studies

Inadequate cord care in neonates is an important modifiable risk factor of cord stump infection, sepsis, and neonatal death, particularly in countries with limited resources. Dry cord care and alcohol 70% are commonly used in multiple developing countries. There is a need to investigate the efficacy and safety of both the cord care to achieve the best outcomes in neonates during this critical period of life. The objective of the study was to compare between dry cord care and topical application of alcohol 70% for cord care in newborn infants in terms of cord separation time (CST) as well as the incidence of omphalitis, sepsis, and neonatal mortality. The analysis was conducted up to April 2019 in MEDLINE, Cochrane Library, Embase, Scopus, and Google Scholar to include randomized clinical trials (RCTs) and quasi-experiments which investigated at least two infant groups receiving either dry cord care or alcohol 70%. Mean differences (MDs) and 95% confidence intervals (CIs) were used to analyze continuous data, while risk ratios (RRs) and 95% CIs were used to analyze dichotomous variables. A total of 13 articles were included (4967 infants, 50.35% females, six RCTs). Alcohol application was significantly associated with longer CST (MD = 1.93 days, 95% CI: 0.80, 3.06) with significant heterogeneity among studies (I² = 97%) while no significant differences were found in the risk of omphalitis. On the other hand, dry cord care was associated with the risk of foul odor at the cord/surrounding tissues (RR = 0.49, 95% CI: 0.28, 0.85) and increased risk of E-coli colonization (RR = 0.75, 95% CI: 0.57, 0.98). Dry cord care is a simple and effective way to shorten CST, particularly in countries with limited resources. However, in light of the limitations of the included studies, future RCTs with higher methodological quality are warranted. The significant heterogeneity among studies is the limitations of the included studies.

Evaluating WHO-Recommended Interventions for Preterm Birth: A Mathematical Model of the Potential Reduction of Preterm Mortality in Sub-Saharan Africa

BACKGROUND

Preterm birth, a leading cause of neonatal mortality, has the highest burden in low-income countries. In 2015, the World Health Organization (WHO) published recommendations for interventions to improve preterm outcomes. Our analysis uses the Maternal and Neonatal Directed Assessment of Technology (MANDATE) model to evaluate the potential effects that WHO-recommended interventions could have had on preterm mortality in sub-Saharan Africa in 2015.

METHODS

We modeled preterm birth subconditions causing mortality (respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, birth asphyxia, and low birth weight). For each subcondition, models were populated with estimates of WHO-recommended intervention prevalence, case fatality, coverage, and efficacy. Various scenarios modeled improved coverage of single and combined interventions compared with baseline.

RESULTS

In 2015, approximately 500,000 neonatal deaths due to preterm birth occurred in sub-Saharan Africa. Single interventions with the greatest impact on preterm mortality included oxygen/continuous positive airway pressure (44,000 lives saved), cord care (38,500 lives saved), and breastfeeding (30,200 lives saved). Combined with improved diagnosis/transfer to a hospital, the impact of interventions showed greater reductions in mortality (oxygen/continuous positive airway pressure, 134,100 lives saved; antibiotics, 28,600 lives saved). Combined interventions had the greatest impact. Together, hospital delivery with comprehensive care for respiratory distress syndrome saved 190,600 lives, and comprehensive thermal care, breastfeeding, and prevention/treatment for sepsis saved 94,400 lives.

CONCLUSION

In 2015, WHO-recommended interventions could have saved the lives of nearly 300,000 infants born preterm in sub-Saharan Africa. Combined interventions are necessary to maximize impact. Mathematical models such as MANDATE can estimate effects on health outcomes to allow health officials to prioritize implementation strategies.

Effect of a participatory intervention in women's self-help groups for the prevention of chronic suppurative otitis media in their children in Jumla Nepal: a cluster-randomised trial

Background

Chronic suppurative otitis media (CSOM) causes preventable deafness and disproportionately affects children living in poverty. Our hypothesis was that health promotion in women’s groups would increase their knowledge, attitudes and practices (KAP) regarding ear disease and reduce the prevalence of CSOM in their children.

Methods

We did a cluster randomised trial in two village development committees (VDCs) in Jumla, Nepal. In July 2014, 30 women’s groups were randomly allocated to intervention or control, stratified by VDC and distance to the road. The intervention groups participated in three sessions of health promotion using the WHO Hearing and Ear Care Training Resource Basic Level. The primary outcome was women’s KAP score and the secondary outcome was prevalence of CSOM in their children at 12 month follow-up. Analyses were by intention to treat. Participants and the research team were not masked to allocation.

Results

In June and July 2014 we recruited 508 women and 937 of their children. 12 months later there was no difference in the women’s KAP score (mean difference 0.14, 95% CI − 0.1 to 0.38, P = 0.25) or the prevalence of CSOM in their children (OR 1.10, 95%CI 0.62 to 1.84, P = 0.75) between intervention and control groups. However, overall, there was a significant improvement in the KAP score (mean difference − 0.51, 95% CI − 0.71,to − 0.31, P < 0.0001) and in the prevalence of CSOM from baseline 11.2% to follow-up 7.1% (P < 0.0001).

Conclusions

Health promotion in women’s groups did not improve maternal KAP or reduce prevalence of CSOM. Over time there was a significant improvement in women’s KAP score and reduction in the prevalence of CSOM which may be attributable to our presence in the community offering treatment to affected children, talking to their parents and providing ciprofloxacin drops to the local health posts. More research is needed in low resource settings to test our findings.

Effect of an integrated neonatal care kit on neonatal health outcomes: a cluster randomised controlled trial in rural Pakistan

Introduction

In 2016, 2.6 million children died during their first month of life. We assessed the effectiveness of an integrated neonatal care kit (iNCK) on neonatal survival and other health outcomes in rural Pakistan.

Methods

We conducted a community-based, cluster randomised, pragmatic, open-label, controlled intervention trial in Rahim Yar Khan, Punjab, Pakistan. Clusters, 150 villages and their lady health workers (LHWs), were randomly assigned to deliver the iNCK (intervention) or standard of care (control). In intervention clusters, LHWs delivered the iNCK and education on its use to pregnant women. The iNCK contained a clean birth kit, chlorhexidine, sunflower oil, a continuous temperature monitor (ThermoSpot), a heat reflective blanket and reusable heat pack. LHWs were also given a hand-held scale. The iNCK was implemented primarily by caregivers. The primary outcome was all-cause neonatal mortality. Outcomes are reported at the individual level, adjusted for cluster allocation. Enrolment took place between April 2014 and July 2015 and participant follow-up concluded in August 2015.

Results

5451 pregnant women (2663 and 2788 in intervention and control arms, respectively) and their 5286 liveborn newborns (2585 and 2701 in intervention and control arms, respectively) were enrolled. 147 newborn deaths were reported, 65 in the intervention arm (25.4 per 1000 live births) compared with 82 in the control arm (30.6 per 1000 live births). Neonatal mortality was not significantly different between treatment groups (risk ratio 0.83, 95% CI 0.58 – 1.18; p = 0.30).

Conclusion

Providing co-packaged interventions directly to women did not significantly reduce neonatal mortality. Further research is needed to improve compliance with intended iNCK use.

Dry care versus chlorhexidine cord care for prevention of omphalitis. Systematic review with meta-analysis

Objective:

to compare the effect of dry care and the application of chlorhexidine to the umbilical cord of newborns at risk of developing omphalitis.

Method:

systematic review with meta-analysis. Clinical trials comparing dry care with the application of clorexidine to evaluate omphalitis were selected. Methodological quality was evaluated using the Consolidated Standards of Reporting Trials.

Results:

the joint analysis of the studies shows a significant decrease in the risk of omphalitis in the chlorhexidine group compared to the dry care group (RR=0.58, CI: 0.53-0.64). However, in the analysis by subgroups, chlorhexidine umbilical cord care did not reduce the risk of omphalitis in hospital births (RR=0.82, CI: 0.64-1.05), in countries with a low infant mortality rate (RR=0.8, CI: 0.5-1.28), or at chlorhexidine concentrations below 4% (RR=0.55, CI: 0.31-1). Chlorhexidine acted as a protective factor at a concentration of 4% (RR=0.58, CI: 0.53-0.64), when applied in cases of home births (RR=0.57, CI: 0.51-0.62), in countries with a high infant mortality rate (RR=0.57, CI: 0.52-0.63).

Conclusion:

dry cord care is effective in countries with low infant mortality rate and in hospital births. However, 4% chlorhexidine for umbilical cord care protects against omphalitis in home births, in countries with a high infant mortality rate.

Effect of chlorhexidine cord application on prevention of neonatal sepsis in developing countries: Systematic review and meta-analysis

OBJECTIVE

The aim of this review was to identify the pooled effect of chlorhexidine cord application on prevention of neonatal sepsis in developing countries.

METHODS

We have conducted systemic review and meta-analysis. Articles were searched from electronic databases such as PubMed, EMBASE, CINHAL, Cochrane central register of controlled trials (CENTRAL), and other sources such as direct Google search, Google Scholar, and POPline. Only randomized controlled trial studies were considered for this review. The effect of chlorhexidine cord application on prevention of neonatal sepsis and mortality was assessed as compared to dry cord care.

RESULTS

Five studies from developing countries were included in the review with a total of 129,293 participants. Pooled result of meta-analysis showed that chlorhexidine cord application reduces neonatal sepsis by 32% as compared to dry cord care (relative risk [RR] 0.68, 95% confidence interval [CI] 0.57-0.81, random effect model, I² =93%). It also indicated that chlorhexidine cord application reduces severe sepsis by 77% (RR 0.23, 95% CI 0.11-0.48, random effect model, I² = 63%) and neonatal mortality reduction by 13 % as compared to dry cord care (RR 0.87, 95% CI 0.79-0.97, random effect model, I² = 0%).

CONCLUSIONS

Chlorhexidine cord application significantly reduces neonatal sepsis and mortality in developing countries. Therefore, we stress the importance of including chlorhexidine cord application into the essential newborn care in the setting with high burden of neonatal mortality. The review protocol was registered at PROSPERO with registration number CRD 42018089204.

'First 1000 days' health interventions in low- and middle-income countries: alignment of South African policies with high-quality evidence

Background: In South Africa (SA), despite adoption of international strategies and approaches, maternal, neonatal and child (MNC) morbidity and mortality rates have not sufficiently declined.

Objectives: To conduct an umbrella review (UR) that identifies interventions in low- and middle-income countries, with a high-quality evidence base, that improve MNC morbidity and mortality outcomes within the first 1000 days of life; and to assess the incorporation of the evidence into local strategies, guidelines and documents.

Methods: We included publications about women and children in the first 1000 days of life; healthcare professionals and community members. Comparators were those who did not receive the intervention. Interventions were pharmacological and non-pharmacological. Outcomes were MNC morbidity and mortality. Authors conducted English language electronic and manual searches (2000–2013). The quality of systematic reviews and meta-analyses (SRs/MAs) were reviewed. Interventions were ranked according to level of evidence; and then aligned with SA strategies, policies and guidelines. A tool to extract data was developed and used by two authors who independently extracted data. Summary measures from MAs or summaries of SRs were reviewed and the specificities of the various interventions listed. A search of all local high-level documents was done and these were assessed to determine the specificities of the recommendations and their alignment to the evidence.

Results: In total, 19 interventions presented in 32 SRs were identified. Overall, SA’s policymakers have sufficiently included high-quality evidence-based interventions into local policies. However, optimal period of birth spacing (two to five years) is not explicitly promoted nor was ante- and postnatal depression adequately incorporated. Antenatal care visits should be increased from four to about eight according to the evidence.

Conclusion: Incorporation of existing evidence into policies can be strengthened in SA. The UR methods are useful to inform policymaking and identify research gaps.

Can community health workers identify omphalitis? A validation study from Southern Province, Zambia

OBJECTIVE

Omphalitis, or umbilical cord infection, is an important cause of newborn morbidity and mortality in low-resource settings. We tested an algorithm that task-shifts omphalitis diagnosis to community-level workers in sub-Saharan Africa.

METHODS

Community-based field monitors and Zambian paediatricians independently evaluated newborns presenting to health facilities in Southern Zambia using a signs and symptoms checklist. Responses were compared against the paediatrician's gold standard clinical diagnosis.

RESULTS

Of 1009 newborns enrolled, 6.2% presented with omphalitis per the gold standard clinical diagnosis. Paediatricians' signs and symptoms with the highest sensitivity were presence of pus (79.4%), redness at the base (50.8%) and newborn flinching when cord was palpated (33.3%). The field monitor's signs and symptoms answers had low correlation with paediatrician's answers; all signs and symptoms assessed had sensitivity <16%.

CONCLUSION

Despite extensive training, field monitors could not consistently identify signs and symptoms associated with omphalitis in the sub-Saharan African setting.

Effective Collaboration for Scaling Up Health Technologies: A Case Study of the Chlorhexidine for Umbilical Cord Care Experience

Facilitating factors for the Chlorhexidine Working Group: (1) strong, transparent leadership by a neutral broker, promoting shared ownership among all members; (2) reliable internal and external communication; (3) well-defined terms of reference building on common interest around a simple, effective health intervention; (4) clear benefits of participation, including access to evidence and technical assistance; and (5) adequate resources to support the secretariat functions.

The global health field is replete with examples of cross-organizational collaborative partnerships, such as networks, alliances, coalitions, task forces, and working groups, often established to tackle a shared global health concern, condition, or threat affecting low-income countries or communities. The purpose of this article is to review factors influencing the effectiveness of a multi-agency global health collaborative effort using the Chlorhexidine Working Group (CWG) as our case study. The CWG was established to accelerate the introduction and global scale-up of chlorhexidine for umbilical cord care to reduce infection-related neonatal morbidity and mortality in low-income countries. Questions included: how current and past CWG members characterized the effectiveness, productivity, collaboration, and leadership of the CWG; what factors facilitated or hindered group function; institutional or individual reasons for participating and length of participation in the CWG; and lessons that might be relevant for future global collaborative partnerships. Data were collected through in-depth, semistructured individual interviews with 19 group members and a review of key guiding documents. Six domains of internal coalition functioning (leadership, interpersonal relationships, task focus, participant benefits and costs, sustainability planning, and community support) were used to frame and describe the functioning of the CWG. Collaboration effectiveness was found to depend on: (1) leadership that maintained a careful balance between discipline and flexibility, (2) a strong secretariat structure that supported the evolution of trust and transparent communication in interpersonal relationships, (3) shared goals that allowed for task focus, (4) diverse membership and active involvement from country-level participants, which created a positive benefit-cost ratio for participants, (5) sufficient resources to support the partnership and build sustainable capacity for members to accelerate the transfer of knowledge, and (6) support from the global health community across multiple organizations. Successful introduction and scale-up of new health interventions require effective collaboration across multiple organizations and disciplines, at both global and country levels. The participatory collaborative partnership approach utilized by the Chlorhexidine Working Group offers an instructive learning case.

Effectiveness of a campaign to implement chlorhexidine use for newborns in rural Haiti

Background

Chlorhexidine topical cord application is recommended to prevent umbilical cord infections in newborns delivered at home in low-resource settings. A community campaign introducing chlorhexidine for the first time in Haiti was developed. Traditional birth attendants (TBAs) were identified as implementers since they typically cut newborns’ cords. TBAs were trained to apply chlorhexidine to the cord and demonstrate this procedure to the mother. Concurrently TBAs explained reasons for using chlorhexidine exclusively instead of traditional cord care practices. The campaign’s effectiveness was evaluated 7–10 days post-delivery using a survey administered by community health workers (CHWs) to 198 mothers.

Results

Nearly all mothers heard about chlorhexidine use and applied it as instructed. Most mothers did not initially report using traditional cord care practices. With further probing, the majority reported covering the cord but few applied an unhygienic substance. No serious cord infections were reported.

Conclusion

The campaign was highly successful in reaching mothers and achieving chlorhexidine use. In this study, the concomitant use of traditional cloth coverings or bindings of the cord did not appear harmful; however more research is needed in this area. This campaign provides a model for implementing chlorhexidine use, especially where trained TBAs and CHWs are present.

Innovative Product Development Partnership Reduced Neonatal Mortality In Nepal Through Improved Umbilical Cord Care

Approximately 40 percent of all newborn deaths in Nepal are attributable to neonatal infections. A randomized controlled trial conducted in Nepal in the period 2002-05 on the application of a solution of the disinfectant chlorhexidine to umbilical cord stumps of newborns showed a reduced risk of infections and death. In response to these results, the Government of Nepal and various partners mobilized to deliver this simple, low-cost intervention on a national scale. We describe the design, development, and maturation of a partnership among the government, technical assistance agencies, and a local pharmaceutical company to create a suitable, commercially available gel product to reduce newborn infections. Essential contributors to the partnership's effectiveness included having a for-profit pharmaceutical company as a fully engaged partner; having responsive, flexible relationships among the partners that evolved over time; and paying attention to competition within the private sector. A less formalized arrangement among partners allowed them to build trust in each other over time. Government stewardship of the program throughout the scale-up process ensured that policy and systems integration were aligned as the program matured.

Maternal cultural practices for neonates' care in upper Egypt

PROBLEM

Little is known about the home practices and care given to neonates born in Egypt.

BACKGROUND

Two thirds of all infant deaths in Egypt occur in the neonatal period and many of these deaths occur in the home environment out of sight of health care providers. Understanding cultural practices and beliefs about caring for neonates may help direct appropriate interventions to improve infant outcomes.

AIM

To describe maternal cultural care practices used with neonates and highlight harmful practices in order to identify areas of required change in care.

METHODS

A descriptive study using a convenience sample of 200 women recruiting from outpatient pediatric facilities in Qena, Egypt. Face to face interviews were used to gather data.

FINDINGS

More than one third (37.5%) of the studied women given birth in the home, and a traditional birth attendant assisted with the majority of home births (90%). Breast-feeding was delayed between 1 and 4days in 27% of the women and they were more likely to use cultural practices, rather than modern medical practices, for neonatal eye and umbilical care. Maternal cultural practices used in the home can be categorized as being harmful, beneficial, and as having no-effect on neonatal health based upon available evidence.

DISCUSSION

A variety of cultural practices are used by women for neonatal care in upper Egypt. Many of these practices may have a negative effect on neonatal health and should be discontinued.

CONCLUSION

Comprehensive interventions are needed to modify women' care practices.

Impact of Chlorhexidine Cord Cleansing on Mortality, Omphalitis and Cord Separation Time Among Facility-Born Babies in Nepal and Bangladesh

Guidance is needed regarding potential extension of the World Health Organization recommendation for cord cleansing with chlorhexidine to babies born in facilities. Among 3223 facility-born babies from Nepal and Bangladesh, mortality was approximately halved among those allocated to the intervention clusters [10.5/1000 vs. 19.4/1000; relative risk (RR): 0.54; 95% confidence interval: 0.30-0.97]. In high-mortality settings, a single policy for home and facility births is warranted.

Neonatal and Perinatal Infections

Lack of success in achieving considerable reductions in neonatal mortality is a contributory factor in failing to achieve Millennium Development Goal 4.2.6 million neonates still die each year, with preterm birth and infections the two leading causes. Maternal infections and environmental and infant factors influence acquisition of viral and bacterial infections in the perinatal and neonatal period. Scaling up evidence-based interventions addressing maternal risk factors and underlying causes could reduce neonatal infections by 84%. The emergence of new infections and increasing antimicrobial resistance present public health challenges that must be addressed to achieve substantial reductions in neonatal mortality.

Efficacy of umbilical cord cleansing with a single application of 4% chlorhexidine for the prevention of newborn infections in Uganda: study protocol for a randomized controlled trial

Background

Yearly, nearly all the estimated worldwide 2.7 million neonatal deaths occur in low- and middle-income countries. Infections, including those affecting the umbilical cord (omphalitis), are a significant factor in approximately a third of these deaths. In fact, the odds of all-cause mortality are 46% higher among neonates with omphalitis than in those without. Five large randomized controlled trials in Asia and Sub-Saharan Africa (SSA) have examined the effect of multiple cord stump applications with 4% chlorhexidine (CHX) for at least 7 days on the risk of omphalitis and neonatal death. These studies, all community-based, show that multiple CHX applications reduced the risk of omphalitis. Of these trials, only one study from South Asia (the Bangladeshi study) and none from Africa examined the effect of a single application of CHX as soon as possible after birth. In this Bangladeshi trial, CHX led to a reduction in the risk of mild-moderate omphalitis and neonatal death. It is important, in an African setting, to explore the effect of a single application among health-facility births. A single application is programmatically much simpler to implement than daily applications for 7 days. Therefore, our study compares umbilical cord cleansing with a single application of 4% CHX at birth with dry cord care among Ugandan babies born in health facilities, on the risk of omphalitis and severe neonatal illness.

Methods

The CHX study is a facility-based, individually randomized controlled trial that will be conducted among 4760 newborns in Uganda. The primary outcomes are severe illness and omphalitis during the neonatal period. Analysis will be by intention-to-treat.

Discussion

This study will provide novel evidence, from a Sub-Saharan African setting, of the effect of umbilical cord cleansing with a single application of 4% CHX at birth and identify modifiable risk factors for omphalitis.

Factors related to choice of place of birth in a district in Nepal

OBJECTIVE

In Nepal, both percentage of women giving birth at health facility and proportion of birth assisted by skilled birth attendant is very low. The purpose of this research was to identify predictors for choice of place of birth: either at home, primary health care facility (including birthing centres) or at tertiary health care facilites (hospitals and clinics).

METHODS

A cross-sectional household survey was conducted in seven village development committee of a district lying in plain area of Nepal: Nawalparasi. A structured interview questionnaire was developed and administered face-to-face. Descriptive analysis along with chi-square test and multinomial logistic regression was used to identify the predictors of giving birth at a health care facility.

RESULTS

Women were significantly more likely to give birth at health care facilities compared to home if the distance was less than one hour, belonged to advantaged caste, had radio, television and motorbike/scooter, decision maker for place of birth was husband, reported their frequency of antenatal (ANC) visits at 4 or more and belonged to age group 15-19.

CONCLUSION

The analysis indicates that husbands of women giving birth influence the choice of place of birth. The findings highlight importance of having four or more ANC visits to the health institutions and that it should be located within one-hour walking distance. Inequity in utilisation of childbirth services at health institutions exists as showed by low utilisation of such services by disadvantaged caste.

Health care providers' perspectives regarding the use of chlorhexidine gel for cord care in neonates in rural Kenya: implications for scale-up

Background

This paper explores the perspectives of health care providers regarding the use of 7.1% Chlorhexidine Digluconate (CHX) gel that releases 4% chlorhexidine for newborn umbilical cord care under a managed access program (MAP) implemented in Bungoma County of Kenya. Understanding the perspectives of providers regarding CHX is important since they play a key role in the health system and the fact that their views could be influenced by prior beliefs and inconsistent practices regarding umbilical cord care.

Methods

Data are from in-depth interviews conducted between April and June 2016 with 39 service providers from 21 facilities that participated in the program. The data were transcribed, typed in Word and analyzed for content. Analysis entailed identifying recurring themes based on the interview guides.

Results

Use of CHX gel for cord care in neonates was acceptable to the health care providers, with all of them supporting scaling up its use throughout the country. Their views were largely influenced by positive outcomes of the medication including fast healing of the cord as reported by mothers, minimal side effects, reduced newborn infections based on what their records showed and mothers’ reports, ease of use that made it simple for them to counsel mothers on how to apply it, positive feedback from mothers which demonstrated satisfaction with the medication, and general acceptance of the medication by the community. They further noted that successful scale-up of the medication required community sensitization, adequate follow-up mechanisms to ensure mothers use the medication correctly, addressing issues of staffing levels and staff training, developing guidelines and protocols for provision of the medication, adopting appropriate service delivery approaches to ensure all groups of mothers are reached, and ensuring constant supply of the medication.

Conclusion

Use of CHX gel for cord care in neonates is likely to be acceptable to health care workers in settings with high prevalence of neonatal morbidity and mortality arising from cord infections. In scaling up the use of the medication in such settings, some of the health systems requirements for successful roll-out can be addressed by programs while others are likely to be a persistent challenge.

Umbilical cord-care practices in low- and middle-income countries: a systematic review

Background

Neonatal sepsis is the third leading cause of deaths for infants in their first month of life. The newly cut umbilical cord can be a pathway for bacteria that can cause newborn sepsis and death. Optimal umbilical cord care practices for newborns and during the first week of life, especially in settings with poor hygiene, has the potential to avoid these preventable neonatal deaths. The purpose of this review of cord care practices is to assist in the development of behavior-change strategies to support introduction of novel cord-care regimens, particularly 7.1% chlorhexidine digluconate for umbilical cord care.

Methods

We searched domestic and international databases for articles that were published in English between January 1, 2000, and August 24, 2016. We found 321 articles and reviewed 65 full-text articles using standardized inclusion criteria. The primary criteria for inclusion was a description of substances applied to the umbilical cord stump in the days following birth.

Results

We included 46 articles in this review of umbilical cord-care practices. Articles included data from 15 low- and middle-income countries in sub-Saharan Africa (8 countries), Asia (5 countries), North Africa (1 country), and Latin America and the Caribbean (1 country). Findings from this review suggest that documentation of cord-care practices is not consistent throughout low- and middle-income countries, yet existing literature depicts a firm tradition of umbilical cord care in every culture. Cord-care practices vary by country and by regions or cultural groups within a country and employ a wide range of substances. The desire to promote healing and hasten cord separation are the underlying beliefs related to application of substances to the umbilical cord. The frequency of application of the substance (either the number of days or the number of times per day the substance was applied), and source and cost of products used is not well-characterized.

Conclusions

This desire to actively care for the umbilical cord of a newborn—as noted in the variety of cord care practices and beliefs identified in this review—points toward the need to contextualize any behavior change approach to align with the local culture.

Use of antiseptic for cord care and its association with neonatal mortality in a population-based assessment in Bihar State, India

OBJECTIVES

Dry cord care is recommended for all births by the Health Ministry in India. We report prevalence of antiseptic cord care in the context of neonatal mortality in the Indian state of Bihar.

DESIGN

Population-based cross-sectional study with multistage stratified random sampling.

SETTING

Households in 1017 clusters in Bihar.

PARTICIPANTS

A representative sample of 12 015 women with a live birth in the last 12 months were interviewed from all 38 districts of Bihar (90.7% participation) in 2014.

PRIMARY AND SECONDARY OUTCOME MEASURES

Use of antiseptic cord care at birth and its association with neonatal mortality using multiple logistic regression.

RESULTS

Topical application of any material on cord was reported by 6534 women (54.4%; 95% CI 53.5% to 55.3%). Antiseptic cord care prevalence was 49.7% (95% CI 48.8% to 50.6%), the majority of which was gentian violet (76.4%). The odds of antiseptic use for cord care were higher in facility births (OR 1.46; 95% CI 1.27 to 1.69) and for deliveries by a qualified health provider (OR 1.44; 95% CI 1.26 to 1.66), but were lower for births that occurred before the expected delivery date (OR 0.77; 95% CI 0.61 to 0.96). A total of 256 (2.1%) newborns died during the neonatal period. The odds of neonatal death were significantly higher for live births with no reported antiseptic use (OR 1.53; 95% CI 1.18 to 1.99), and this association persisted when live births in health facilities were considered separately.

CONCLUSIONS

Even though dry cord care is recommended by health authorities in India, half the women in this study reported use of antiseptic for cord care mainly with gentian violet; and its use had beneficial effect on neonatal mortality. These findings suggest that the application of readily available gentian violet for cord care in less developed settings should be assessed further for its potential beneficial influence on neonatal mortality.

Dry Care Versus Antiseptics for Umbilical Cord Care: A Cluster Randomized Trial

BACKGROUND AND OBJECTIVES

In developed countries, where omphalitis has become rare and related mortality nil, benefits of antiseptic use in umbilical cord care have not been demonstrated. We aimed to assess the noninferiority of dry care compared with antiseptics in France where antiseptic use is widespread.

METHODS

We conducted a noninferiority, cluster-randomized, 2-period crossover trial, in 6 French university maternity units including all infants born after 36 weeks' gestation. Maternity units were randomly assigned to provide either their usual antiseptic care or a dry care umbilical cord method for a 4-month period, and then units switched to the alternate cord cleansing method for a 4-month period. The primary outcome was neonatal omphalitis, adjudicated by an independent blinded committee based on all available photographs, clinical, and bacteriological data. We used a noninferiority margin of 0.4%. Analysis was performed per protocol and by intention to treat.

RESULTS

Among 8698 participants, omphalitis occurred in 3 of 4293 (0.07%) newborns in the dry care group and in none of the 4404 newborns in the antiseptic care group (crude difference: 0.07; 95% confidence interval: -0.03 to 0.21). Late neonatal infection, parental appreciation of difficulty in care, and time to separation of the cord were not significantly different between the 2 groups.

CONCLUSIONS

Dry cord was noninferior to the use of antiseptics in preventing omphalitis in full-term newborns in a developed country. Antiseptic use in umbilical cord care is therefore unnecessary, constraining, and expensive in high-income countries and may be replaced by dry care.

Invasive Group A Streptococcus Infection among Children, Rural Kenya

These infections cause serious illness, especially in neonates.

To determine the extent of group A Streptococcus (GAS) infections in sub-Saharan Africa and the serotypes that cause disease, we analyzed surveillance data for 64,741 hospital admissions in Kilifi, Kenya, during 1998–2011. We evaluated incidence, clinical presentations, and emm types that cause invasive GAS infection. We detected 370 cases; of the 369 for which we had data, most were skin and soft tissue infections (70%), severe pneumonia (23%), and primary bacteremia (14%). Overall case-fatality risk was 12%. Incidence of invasive GAS infection was 0.6 cases/1,000 live births among neonates, 101/100,000 person-years among children <1 year of age, and 35/100,000 among children <5 years of age. Genome sequencing identified 88 emm types. GAS causes serious disease in children in rural Kenya, especially neonates, and the causative organisms have considerable genotypic diversity. Benefit from the most advanced GAS type–specific vaccines may be limited, and efforts must be directed to protect against disease in regions of high incidence.

Effectiveness of 4% chlorhexidine umbilical cord care on neonatal mortality in Southern Province, Zambia (ZamCAT): a cluster-randomised controlled trial

BACKGROUND

Chlorhexidine umbilical cord washes reduce neonatal mortality in south Asian populations with high neonatal mortality rates and predominantly home-based deliveries. No data exist for sub-Saharan African populations with lower neonatal mortality rates or mostly facility-based deliveries. We compared the effect of chlorhexidine with dry cord care on neonatal mortality rates in Zambia.

METHODS

We undertook a cluster-randomised controlled trial in Southern Province, Zambia, with 90 health facility-based clusters. We enrolled women who were in their second or third trimester of pregnancy, aged at least 15 years, and who would remain in the catchment area for follow-up of 28 days post-partum. Newborn babies received clean dry cord care (control) or topical application of 10 mL of a 4% chlorhexidine solution once per day until 3 days after cord drop (intervention), according to cluster assignment. We used stratified, restricted randomisation to divide clusters into urban or two rural groups (located <40 km or ≥40 km to referral facility), and randomly assigned clusters (1:1) to use intervention (n=45) or control treatment (n=45). Sites, participants, and field monitors were aware of their study assignment. The primary outcomes were all-cause neonatal mortality within 28 days post-partum and all-cause neonatal mortality within 28 days post-partum among babies who survived the first 24 h of life. Analysis was by intention to treat. Neonatal mortality rate was compared with generalised estimating equations. This study is registered at ClinicalTrials.gov (NCT01241318).

FINDINGS

From Feb 15, 2011, to Jan 30, 2013, we screened 42 356 pregnant women and enrolled 39 679 women (mean 436·2 per cluster [SD 65·3]), who had 37 856 livebirths and 723 stillbirths; 63·8% of deliveries were facility-based. Of livebirths, 18 450 (99·7%) newborn babies in the chlorhexidine group and 19 308 (99·8%) newborn babies in the dry cord care group were followed up to day 28 or death. 16 660 (90·0%) infants in the chlorhexidine group had chlorhexidine applied within 24 h of birth. We found no significant difference in neonatal mortality rate between the chlorhexidine group (15·2 deaths per 1000 livebirths) and the dry cord care group (13·6 deaths per 1000 livebirths; risk ratio [RR] 1·12, 95% CI 0·88-1·44). Eliminating day 0 deaths yielded similar findings (RR 1·12, 95% CI 0·86-1·47).

INTERPRETATION

Despite substantial reductions previously reported in south Asia, chlorhexidine cord applications did not significantly reduce neonatal mortality rates in Zambia. Chlorhexidine cord applications do not seem to provide clear benefits for newborn babies in settings with predominantly facility-based deliveries and lower (<30 deaths per 1000 livebirths) neonatal mortality rates.

Umbilical Cord Care in the Newborn Infant

Postpartum infections remain a leading cause of neonatal morbidity and mortality worldwide. A high percentage of these infections may stem from bacterial colonization of the umbilicus, because cord care practices vary in reflection of cultural traditions within communities and disparities in health care practices globally. After birth, the devitalized umbilical cord often proves to be an ideal substrate for bacterial growth and also provides direct access to the bloodstream of the neonate. Bacterial colonization of the cord not infrequently leads to omphalitis and associated thrombophlebitis, cellulitis, or necrotizing fasciitis. Various topical substances continue to be used for cord care around the world to mitigate the risk of serious infection. More recently, particularly in high-resource countries, the treatment paradigm has shifted toward dry umbilical cord care. This clinical report reviews the evidence underlying recommendations for care of the umbilical cord in different clinical settings.
