Risk factors for mortality among neonates admitted to a special care unit in a low-resource setting

Amenable Mortality in Children under 5: An Indicator for Identifying Inequalities in Healthcare Delivery: A Review

Universal health coverage has been proposed as a strategy to improve health in low- and middle-income countries, but this depends on a good provision of health services. Under-5 mortality (U5M) reflects the quality of health services, and its reduction has been a milestone in modern society, reducing global mortality rates by more than two-thirds between 1990 and 2020. However, despite these impressive achievements, they are still insufficient, and most deaths in children under 5 can be prevented with the provision of timely and high-quality health services. The aim of this paper is to conduct a literature review on amenable (treatable) mortality in children under 5. This indicator is based on the concept that deaths from certain causes should not occur in the presence of timely and effective medical care. A systematic and exhaustive review of available literature on amenable mortality in children under 5 was conducted using MEDLINE/PubMed, Cochrane CENTRAL, OVID medline, Scielo, Epistemonikos, ScienceDirect, and Google Scholar in both English and Spanish. Both primary sources, such as scientific articles, and secondary sources, such as bibliographic indices, websites, and databases, were used. Results: The main cause of amenable mortality in children under 5 was respiratory disease, and the highest proportion of deaths occurred in the perinatal period. Approximately 65% of avoidable deaths in children under 5 were due to amenable mortality, that is, due to insufficient quality in the provision of health services. Most deaths in all countries and around the world are preventable, primarily through effective and timely access to healthcare (amenable mortality) and the management of public health programs focused on mothers and children (preventable mortality).

Identifying neonates at risk for post-discharge mortality in Dar es Salaam, Tanzania, and Monrovia, Liberia: Derivation and internal validation of a novel risk assessment tool

INTRODUCTION

The immediate period after hospital discharge carries a large burden of childhood mortality in sub-Saharan Africa. Our objective was to derive and internally validate a risk assessment tool to identify neonates discharged from the neonatal ward at risk for 60-day post-discharge mortality.

METHODS

We conducted a prospective observational cohort study of neonates discharged from Muhimbili National Hospital in Dar es Salaam, Tanzania, and John F Kennedy Medical Centre in Monrovia, Liberia. Research staff called caregivers to ascertain vital status up to 60 days after discharge. We conducted multivariable logistic regression analyses with best subset selection to identify socioeconomic, demographic, clinical, and anthropometric factors associated with post-discharge mortality. We used adjusted log coefficients to assign points to each variable and internally validated our tool with bootstrap validation with 500 repetitions.

RESULTS

There were 2344 neonates discharged and 2310 (98.5%) had post-discharge outcomes available. The median (IQR) age at discharge was 8 (4, 15) days; 1238 (53.6%) were male. In total, 71 (3.1%) died during follow-up (26.8% within 7 days of discharge). Leaving against medical advice (adjusted OR [aOR] 5.62, 95% CI 2.40 to 12.10) and diagnosis of meconium aspiration (aOR 6.98, 95% CI 1.69 to 21.70) conferred the greatest risk for post-discharge mortality. The risk assessment tool included nine variables (total possible score=63) and had an optimism corrected area under the receiver operating characteristic curve of 0.77 (95% CI 0.75 to 0.80). A score of ≥6 was most optimal (sensitivity 68.3% [95% CI 64.8% to 71.5%], specificity 72.1% [95% CI 71.5% to 72.7%]).

CONCLUSIONS

A small number of factors predicted all-cause, 60-day mortality after discharge from neonatal wards in Tanzania and Liberia. After external validation, this risk assessment tool may facilitate clinical decision making for eligibility for discharge and the direction of resources to follow-up high risk neonates.

Risk Factors for Neonatal Mortality in Rural Iganga District, Eastern Uganda: A Case Control Study

Background

Reducing Neonatal Mortality (NM) is vital in decreasing mortality in children below 5 years. Uganda has reported a significant reduction in under 5 and infant mortality over the past decade while NM has stagnated at 27 deaths per 1,000 live births. The NMR of 34 deaths per 1,000 live births in Eastern Uganda is higher than the national rate.

Objective

To determine risk factors for neonatal mortality in rural Iganga district, Eastern Uganda.

Methods

A matched case-control study was conducted between February and July 2019 in Nakigo and Nakalama sub-counties of Iganga district. Cases (n=91) were neonates that died and the controls (n=182) were live neonates at 1 month. Data on maternal, social demographic and neonatal variables were collected from mothers of neonates at household level. Descriptive analysis was performed to determine the profile of study participants. Data was presented as mean (and standard deviation) for continuous variables, and frequencies with percentages for categorical variables. A conditional logistic regression was performed to calculate Odds Ratios and to establish factors that were independently associated with risk of neonatal Mortality.

Results

Giving birth to 5 or more children (AOR=2.88, 95% CI =1.25-6.63), attending less than 4 antenatal care visits (AOR= 2.27, 95% CI= 1.14-5.54), and giving birth to twins (AOR= 6.30, 95% CI=1.24-32.0) were the risk factors for neonatal mortality while delivering from health facilities was protective (AOR= 0.26, 95% CI= 0.12-0.56).

Conclusion

The risk factors for NM are: - giving birth to 5 or more children, attendance of less than 4 antenatal care visits and giving birth to twins. To reduce the risk of NM, the study re-emphasises the need to put more focus on neonatal care during pregnancy and child birth. The study findings can be utilised to determine priorities for reducing the risk of NM in rural settings.

Neonatal Mortality at Felege Hiwot Comprehensive Specialized Hospital in Ethiopia Over 5 years: Trends and Associated Factors

Background

Globally, neonatal mortality remains a serious catastrophic problem for newborns, particularly in a low-resource setting. There were no neonatal mortality trend studies in the study area.

Objective

This study aimed to determine the trends and risk factors of neonatal mortality at the neonatal intensive care unit of Felege Hiwot Comprehensive Specialized Hospital, Northwest Ethiopia.

Methods

An institution-based retrospective cross-sectional study was conducted among 870 admitted neonates from January 1, 2016 to December 31, 2020 in the neonatal intensive care unit by a stratified simple random sampling technique. Data were entered into EpiData and then exported to STATA 14.0 for analysis. A linear regression statistical model was used for trend analysis and binary logistic regression was carried out to identify explanatory variables of neonatal mortality.

Results

Overall, neonatal mortality averagely increased by 2.1% per year throughout the 5 consecutive years. In this study, rural residency [adjusted odds ratio (AOR): 1.96, 95% confidence interval (CI): (1.26, 3.06)], birth asphyxia (AOR: 7.73, 95% CI: 4.31, 13.84), congenital deformity (AOR: 3.61, 95% CI: 1.17, 11.18), low birth weight (AOR: 2.13, 95% CI: 1.23, 3.67), respiratory distress syndrome (AOR: 3.32, 95% CI: 1.97, 5.59), Ambu-bag resuscitation (AOR: 0.16, 95% CI: 0.07, 0.38), taking antibiotics (AOR: 0.50, 95% CI: 0.27, 0.90), glucose (AOR: 0.47, 95% CI: 0.30, 0.72), and oxygen (AOR: 0.26, 95% CI: 0.16, 0.41) were associated with neonatal mortality.

Conclusions

This 5-year trend analysis revealed an increased trend of NMR, indicating more work is still needed to make progress toward meeting the SDG goal by 2030. Rural residency, birth asphyxia, congenital deformity, low birth weight, respiratory distress syndrome, Ambu-bag resuscitation, taking antibiotics, glucose, and oxygen were associated with neonatal mortality. Therefore, all stakeholders shall give due attention to reducing this timely-increasing trend of neonatal mortality.

Factors influencing hypothermia in very low/extremely low birth weight infants: a meta-analysis

Introduction

Previous studies have explored factors that influence the occurrence of hypothermia in very low/extremely low birth weight (VLBW/ELBW) infants, but the factors associated with hypothermia in VLBW or ELBW infants remain inadequately evaluated due to limited prospective data and inconsistency in study populations. Therefore, it is necessary to systematically evaluate the risk factors of hypothermia in VLBW/ELBW infants in order to provide a theoretical basis for clinical practice.

Methods

PubMed and other databases were used to search for case-control or cohort studies on factors influencing the occurrence of hypothermia in VLBW/ELBW infants. The search time was set from database creation to June 30th, 2022. Literature screening, quality evaluation, and data extraction were performed independently by two investigators according to predefined inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.3.

Results

A total of 10 papers were finally included in this study and 12 factors were established by meta-analysis: body weight (six papers), failure to keep warm in time (three papers), neonatal resuscitation (seven papers), gestational age (three papers), premature rupture of membranes (three papers), maternal combined complications (four papers), cesarean section (six papers), antenatal steroids (four papers), multiple birth (two papers), small for gestational age (two papers), 1 min Apgar score (three papers), and 5 min Apgar score (three papers). Since only one study included race, age (hour), socio-economic status, and spontaneous labor, these factors could not be fitted into RevMan 5.3 for the analysis.

Conclusion

Although there were differences in the study design of the included literature, the influencing factors described in each study were relatively similar. The influencing factors identified in this study may contribute to the construction of related intervention strategies for hypothermia in VLBW/ELBW infants.

Determinants of neonatal mortality among neonates admitted to neonatal intensive care unit of Dessie comprehensive and specialized hospital, Northeast Ethiopia; An unmatched case-control study

Background

According to the World health organization, neonatal mortality is defined as the death of babies within the first 28 days of their lives. The newborn period is the most vulnerable period for a child's survival, with the bulk of neonatal deaths occurring on the first day and week. According to a recent study, about a third of all newborn deaths occur within the first day of life, and nearly three-quarters occur within the first week. This study aimed to assess the determinants of neonatal mortality among neonates admitted to the neonatal intensive care unit in Dessie comprehensive and specialized hospital, northeast Ethiopia.

Methodology

Health institution-based unmatched case-control study was conducted among neonates admitted to Dessie comprehensive and specialized hospital, Ethiopia from February 01 up to March 30, 2020. After keeping cases and controls in separate frames, study participants were chosen using a simple random sampling procedure until the sample size was met. Epi data version 7.0 and SPSS version 25 were used for data entry and analysis respectively. P ≤ 0.05 was used as a cut point of statistical significance in multivariable binary logistic regression.

Results

A total of 698 (233 cases and 465 controls) participated in the study. Pregnancy induced hypertension (AOR = 3.02; 95% CI; 1.47-6.17), public hospital delivery (AOR = 3.44; 95% CI; 1.84-6.42), prematurity (AOR = 2.06; 95% CI; 1.43-2.96), being referred (AOR = 4.71; 95% CI; 3.01-7.39), and hypothermia (AOR = 2.44; 95% CI; 1.56-3.82) were determinant factors of neonatal mortality.

Conclusion

Pregnancy-induced hypertension, public hospital delivery, prematurity, referral, and hypothermia were found to be the determinant factors of neonatal mortality. It would be important to give due attention to neonates delivered from mothers with a history of hypertensive disorder. Besides better to give due attention to neonates delivered in public health institutions, prematurely delivered, referred, and hypothermic neonates. Lastly, further research should be conducted to investigate the additional determinants of neonatal mortality.

Risk factors for mortality in a hospitalised neonatal cohort in Botswana

OBJECTIVES

A disproportionate number of neonatal deaths occur in low/middle-income countries, with sepsis a leading contributor of mortality. In this study, we investigate risk factors for mortality in a cohort of high-risk hospitalised neonates in Botswana. Independent predictors for mortality for infants experiencing either a sepsis or a non-sepsis-related death are described.

METHODS

This is a prospective observational cohort study with infants enrolled from July to October 2018 at the neonatal unit (NNU) of Princess Marina Hospital (PMH) in Gaborone, Botswana. Data on demographic, clinical and unit-specific variables were obtained. Neonates were followed to death or discharge, including transfer to another hospital. Death was determined to be infectious versus non-infectious based on primary diagnosis listed on day of death by lead clinician on duty.

RESULTS

Our full cohort consisted of 229 patients. The overall death rate was 227 per 1000 live births, with cumulative proportion of deaths of 22.7% (n=47). Univariate analysis revealed that sepsis, extremely low birth weight (ELBW) status, hypoxic ischaemic encephalopathy, critical illness and infants born at home were associated with an increased risk of all-cause mortality. Our multivariate model revealed that critical illness (HR 3.07, 95% CI 1.56 to 6.03) and being born at home (HR 4.82, 95% CI 1.76 to 13.19) were independently associated with all-cause mortality. Low birth weight status was independently associated with a decreased risk of mortality (HR 0.24, 95% CI 0.11 to 0.53). There was a high burden of infection in the cohort with more than half of infants (140, 61.14%) diagnosed with sepsis at least once during their NNU admission. Approximately 20% (n=25) of infants with sepsis died before discharge. Our univariate subanalysis of the sepsis cohort revealed that ELBW and critical illness were associated with an increased risk of death. These findings persisted in the multivariate model with HR 3.60 (95% CI 1.11 to 11.71) and HR 2.39 (95% CI 1 to 5.77), respectively.

CONCLUSIONS

High rates of neonatal mortality were noted. Urgent interventions are needed to improve survival rates at PMH NNU and to prioritise care for critically ill infants at time of NNU admission, particularly those born at home and/or of ELBW.

Training on the Silverman and Andersen score improved how special care unit nurses assessed neonatal respiratory distress in a low-resource setting

AIM

Identifying the severity of neonatal respiratory distress (RD) is essential, so that resources can be appropriately allocated. We assessed the ability of nurses to grade neonatal RD in a low-resource setting before and after they were trained to use a dedicated scoring tool.

METHODS

The study was conducted in the Special Care Unit of St Luke Wolisso Hospital, Ethiopia. Ten nurses reviewed nine local video recordings and graded neonatal RD without a standardised method, which was current practice, and then after they were trained to use the Silverman and Andersen score. The data were analysed using the McNemar test and Cohen's kappa.

RESULTS

Training increased the identification of mild RD from 63% to 93% (p = 0.008) and moderate RD from 40% to 73% (p = 0.03). Severe RD was 93% before and 90% after training (p = 0.99). Overall, the agreement improved from kappa 0.59 to 0.84, mainly by reducing the overestimation of milder degrees of RD.

CONCLUSION

Being trained on how to use the Silverman and Andersen score improved the ability of nurses to identify mild and moderate neonatal RD. This improvement has the potential to optimise the use of equipment, staff and time.

Early neonatal mortality is modulated by gestational age, birthweight and fetal heart rate abnormalities in the low resource setting in Tanzania - a five year review 2015-2019

BACKGROUND

Early Neonatal mortality (ENM) (< 7 days) remains a significant problem in low resource settings. Birth asphyxia (BA), prematurity and presumed infection contribute significantly to ENM. The study objectives were to determine: first, the overall ENM rate as well as yearly ENM rate (ENMR) from 2015 to 2019; second, the influence of decreasing GA (< 37 weeks) and BW (< 2500 g) on ENM; third, the contribution of intrapartum and delivery room factors and in particular fetal heart rate abnormalities (FHRT) to ENM; and fourth, the Fresh Still Birth Rates (FSB) rates over the same time period.

METHODS

Retrospective cohort study undertaken in a zonal referral teaching hospital located in Northern Tanzania. Labor and delivery room data were obtained from 2015 to 2019 and included BW, GA, fetal heart rate (FHRT) abnormalities, bag mask ventilation (BMV) during resuscitation, initial temperature, and antenatal steroids use. Abnormal outcome was ENM < 7 days. Analysis included t tests, odds ratios (OR), and multivariate regression analysis.

RESULTS

The overall early neonatal mortality rate (ENMR) was 18/1000 livebirths over the 5 years and did not change significantly comparing 2015 to 2019. Comparing year 2018 to 2019, the overall ENMR decreased significantly (OR 0.62; 95% confidence interval (CI) 0.45-0.85) as well as infants ≥37 weeks (OR 0.45) (CI 0.23-0.87) and infants < 37 weeks (OR 0.57) (CI 0.39-0.84). ENMR was significantly higher for newborns < 37 versus ≥37 weeks, OR 10.5 (p < 0.0001) and BW < 2500 versus ≥2500 g OR 9.9. For infants < 1000 g / < 28 weeks, the ENMR was ~ 588/1000 livebirths. Variables associated with ENM included BW - odds of death decreased by 0.55 for every 500 g increase in weight, by 0.89 for every week increase in GA, ENMR increased 6.8-fold with BMV, 2.6-fold with abnormal FHRT, 2.2-fold with no antenatal steroids (ANS), 2.6-fold with moderate hypothermia (all < 0.0001). The overall FSB rate was 14.7/1000 births and decreased significantly in 2019 when compared to 2015 i.e., 11.3 versus 17.3/1000 live births respectively (p = 0.02).

CONCLUSION

ENM rates were predominantly modulated by decreasing BW and GA, with smaller/ less mature newborns 10-fold more likely to die. ENM in term newborns was strongly associated with FHRT abnormalities and when coupled with respiratory depression and BMV suggests BA. In smaller newborns, lack of ACS exposure and moderate hypothermia were additional associated factors. A composite perinatal approach is essential to achieve a sustained reduction in ENMR.
