The global burden of neonatal hypothermia: systematic review of a major challenge for newborn survival

Thermal care of newborns: drying and bathing practices in Malawi and Bangladesh

Background

Thermal care of newborns is one of the recommended strategies to reduce hypothermia, which contributes to neonatal morbidity and mortality. However, data on these two topics have not been collected at the national level in many surveys. In this study, we examine two elements of thermal care: drying and delayed bathing of newborns after birth with the objectives of examining how two countries collected such data and then looking at various associations of these outcomes with key characteristics. Further, we examine the data for potential data quality issues as this is one of the first times that such data are available at the national level.

Methods

We use data from two nationally-representative household surveys: the Malawi Multiple Indicator Cluster Survey 2014 and the Bangladesh Demographic and Health Survey 2014. We conduct descriptive analysis of the prevalence of these two newborn practices by various socio-demographic, economic and health indicators.

Results

Our results indicate high levels of immediate drying/drying within 1 hour in Malawi (87%). In Bangladesh, 84% were dried within the first 10 minutes of birth. Bathing practices varied in the two settings; in Malawi, only 26% were bathed after 24 hours but in Bangladesh, 87% were bathed after the same period. While in Bangladesh there were few newborns who were never bathed (less than 5%), in Malawi, over 10% were never bathed. Newborns delivered by a skilled provider tended to have better thermal care than those delivered by unskilled providers.

Conclusion

These findings reveal gaps in coverage of thermal care and indicate the need to further develop the role of unskilled providers who can give unspecialized care as a means to improve thermal care for newborns. Further work to harmonize data collection methods on these topics is needed to ensure comparable data across countries.

Thermal Effect of a Woolen Cap in Low Birth Weight Infants During Kangaroo Care

BACKGROUND AND OBJECTIVES

World Health Organization guidelines recommend covering the head during kangaroo mother care (KMC), but the effect of a cap on neonatal thermal control during KMC remains to be defined. Our objective was to assess the effectiveness and safety of a woolen cap in maintaining low birth weight infants (LBWIs) in normal thermal range during KMC.

METHODS

Three hundred LBWI candidates for KMC in 3 African hospitals were randomly assigned to KMC with (CAP group) or without (NOCAP group) a woolen cap in a 1:1 ratio during the first week after birth. Axillary temperature was measured every 6 hours. Maternal and room temperature and adherence to skin-to-skin contact were registered at the same time points.

RESULTS

A total number of 5064 measurements were recorded (median 19 measurements per subject; interquartile range: 10-25). Mean time spent in normal temperature range was 55% (SD 24) in CAP and 56% (SD 24) in NOCAP groups. Multivariable analysis estimated a rate ratio of 0.92 (95% confidence interval: 0.84 to 1.00; P = .06) for the effect of the cap versus no cap on time spent in the normal temperature range.

CONCLUSIONS

In these 3 African, low-resource settings and so many days post birth, the use of a woolen cap was safe but provided no advantages in maintaining LBWI in the normal thermal range while being in a KMC ward. LBWIs spent only half of the time in the normal temperature range despite warm rooms and skin-to-skin contact. Maintaining normothermia in LBWIs remains an unfinished challenge in low-resource settings.

Kangaroo mother care for clinically unstable neonates weighing ≤2000 g: Is it feasible at a hospital in Uganda?

BACKGROUND

Kangaroo mother care (KMC) for stable neonates ≤2000 g (g) is associated with decreased mortality, sepsis, hypothermia, and length of stay compared to conventional care. The World Health Organization states that KMC "should be initiated… as soon as newborns are clinically stable" [12]. However, the majority of deaths occur in unstable neonates. We aimed to determine the proportion of admitted neonates meeting proposed instability criteria, assess the feasibility of providing KMC to unstable neonates, and evaluate the acceptability of this intervention to parents and providers at Jinja Regional Referral Hospital in Uganda.

METHODS

This was a mixed-methods study. We recorded data including birthweight, chronological age, and treatments administered from medical charts, and calculated the percentage of clinically unstable neonates, defined as the need for ≥2 medical therapies in the first 48 hours of admission. We enrolled a sample of neonates meeting pre-defined instability criteria. Mothers were counselled to provide KMC as close to continuously as possible. We calculated the median duration of KMC per episode and per day. To explore acceptability, we conducted semi-structured interviews with parents and newborn unit care providers, and analysed data using the thematic content approach.

FINDINGS

We included 254 neonates in the audit, 10 neonates in the feasibility sub-study, and 20 participants in the acceptability sub-study. Instability criteria were easily implementable, identifying 89% of neonates as unstable in the audit. The median duration of individual KMC episodes ranged from 115 to 134 minutes. The median daily duration ranged from 4.5 to 9.7 hours. Seventy-five percent of interviewees felt KMC could be used in neonates concurrently receiving other medical therapies. Barriers included lack of resources (beds/space, monitoring devices), privacy issues, inadequate education, and difficulties motivating mothers to devote time to KMC. Recommendations included staff/peer counselling, resources, family support, and community outreach.

CONCLUSIONS

There remains a need for an evidence-based approach to consistently define stability criteria for KMC to improve care. We found that KMC for unstable neonates weighing ≤2000g was feasible and acceptable at Jinja Hospital in Uganda. Randomised controlled trials are needed to demonstrate the effect of KMC on survival among unstable neonates in low-resource settings.

Kangaroo mother care for the prevention of neonatal hypothermia: a randomised controlled trial in term neonates

OBJECTIVE

To test the hypothesis that kangaroo mother care (KMC) initiated either at birth or at 1 hour after birth reduces moderate or severe hypothermia in term neonates at (A) 1 hour after birth and (B) at discharge when compared with standard thermoregulation care.

METHODS

Term neonates born at a tertiary delivery centre in Zambia were randomised in two phases (phase 1: birth to 1 hour, phase 2: 1 hour to discharge) to either as much KMC as possible in combination with standard thermoregulation care (KMC group) or to standard thermoregulation care (control group). The primary outcomes were moderate or severe hypothermia (axillary temperature <36.0°C) at (A) 1 hour after birth and (B) at discharge.

RESULTS

The proportion of neonates with moderate or severe hypothermia did not differ between the KMC and control groups at 1 hour after birth (25% vs 27%, relative risk (RR)=0.93, 95% CI 0.59 to 1.4, P=0.78) or at discharge (7% vs 2%, RR=2.8, 95% CI 0.6 to 13.9, P=0.16). Hypothermia was not found among the infants who had KMC for at least 9 hours or 80% of the hospital stay.

CONCLUSIONS

KMC practised as much as possible in combination with standard thermoregulation care initiated either at birth or at 1 hour after birth did not reduce moderate or severe hypothermia in term infants compared with standard thermoregulation care. The current study also shows that duration of KMC either for at least 80% of the time or at least 9 hours during the day of birth was effective in preventing hypothermia in term infants.

Use of Plan-Do-Study-Act cycles to decrease incidence of neonatal hypothermia in the labor room

Background

Body temperature of a neonate continues to be under-documented, under-recognized, and under-managed, even though studies have shown that neonatal hypothermia increases mortality and morbidity. We aimed to reduce neonatal hypothermia (body temperature <36.5 °C) at 1 h following normal vaginal delivery in term and late preterm neonates in delivery room from 50% at baseline to less than 10% by 6 weeks.

Methods

We implemented a quality improvement (QI) initiative using the rapid-cycle Plan-Do-Study-Act approach (PDSA) improvement model and the project was conducted from 15 Jan 2017 to 25 Feb 2017. All singleton neonates with gestational ages above 34 completed weeks born by vaginal delivery were targeted. Exclusion criteria included neonates needing any form of resuscitation, those developing respiratory distress after birth needing any form of respiratory support or observation in NICU. We ran PDSA cycles (including pre-warmed cloths, skin to skin care with mother, early breast feeding, delaying weight check by 1 h and checklist of planned steps), every week, after taking the baseline data in the first week.

Results

A total of 46 neonates were studied. After 4 PDSA cycles, incidence of neonatal hypothermia at 1 h of birth dropped to zero from 50% at baseline and we were able to sustain 100% normal temperature (36.5-37.5 °C) since then.

Conclusion

This QI project has significantly reduced the incidence of hypothermia in term and late preterm neonates born by vaginal delivery in our institute.

EFEITO DE DUAS TÉCNICAS DE BANHO DE IMERSÃO NA TEMPERATURA AXILAR DE RECÉM-NASCIDOS PRÉ-TERMOS: ESTUDO PILOTO

RESUMO Objetivo: comparar as temperaturas axilares pós-banho de imersão de recém-nascidos pré-termos envoltos e não em lençol. Método: estudo piloto, do tipo ensaio clínico cruzado; participaram 15 neonatos pré-termos, clinicamente estáveis internados na unidade neonatal, que receberam os dois tipos de banho em intervalo, entre 24 e 48 horas, seguindo uma lista de randomização da sequência dos banhos. O teste t-Student pareado e o valor p ≤ 0,05 e IC 95% foram adotados. Resultados: as temperaturas do ambiente pré-banhos e da água do banho e axilar apresentaram homogeneidade entre os grupos. As médias da temperatura axilar dos recém-nascidos no 10°e 20° minutos após os banhos foram similares. Independente da técnica, os recém-nascidos apresentaram leve hipotermia pós-banho. Conclusão: estudos sobre o efeito do banho de imersão nos parâmetros fisiológicos e comportamentais são necessários para avaliar a segurança do procedimento.

Impact of hypothermia on implementation of CPAP for neonatal respiratory distress syndrome in a low-resource setting

BACKGROUND

Neonatal hypothermia is widely associated with increased risks of morbidity and mortality, but remains a pervasive global problem. No studies have examined the impact of hypothermia on outcomes for preterm infants treated with CPAP for respiratory distress syndrome (RDS).

METHODS

This retrospective analysis assessed the impact of hypothermia on outcomes of 65 neonates diagnosed with RDS and treated with either nasal oxygen (N = 17) or CPAP (N = 48) in a low-resource setting. A classification tree approach was used to develop a model predicting survival for subjects diagnosed with RDS.

FINDINGS

Survival to discharge was accurately predicted based on three variables: mean temperature, treatment modality, and mean respiratory rate. None of the 23 neonates with a mean temperature during treatment below 35.8°C survived to discharge, regardless of treatment modality. Among neonates with a mean temperature exceeding 35.8°C, the survival rate was 100% for the 31 neonates treated with CPAP and 36.4% for the 11 neonates treated with nasal oxygen (p<0.001). For neonates treated with CPAP, outcomes were poor if more than 50% of measured temperatures indicated hypothermia (5.6% survival). In contrast, all 30 neonates treated with CPAP and with more than 50% of temperature measurements above 35.8°C survived to discharge, regardless of initial temperature.

CONCLUSION

The results of our study suggest that successful implementation of CPAP to treat RDS in low-resource settings will require aggressive action to prevent persistent hypothermia. However, our results show that even babies who are initially cold can do well on CPAP with proper management of hypothermia.

Body temperatures of very low birth weight infants on admission to a neonatal intensive care unit

OBJECTIVE

Hypothermia occurs frequently in the first minutes after birth in preterm infants. Hyperthermia also occurs, often as a consequence of efforts to provide thermal support. Both hypothermia and hyperthermia are potentially harmful. Our objective was to examine the distribution of admission temperatures of very low birth weight (VLBW) infants, the effect of gestational age on admission temperatures, and the time required for correction of low temperatures.

METHODS

Admission axillary temperatures were retrieved from the medical records for all VLBW infants born in our hospital during a 5-year period. The temperatures were classified as severe (<35.0 °C), moderate (35.0-35.9 °C), or mild (36.0-36.4 °C) hypothermia, normothermia (36.5-37.4 °C), or hyperthermia (≥37.5 °C). The relationship between gestational age and admission temperature was examined. In addition, we analyzed the time required for normalization of low temperatures.

RESULTS

Overall, 12% of infants were severely hypothermic, 40% moderately hypothermic, 27% mildly hypothermic, 19% normothermic, and 2% hyperthermic. Gestational age was inversely related to hypothermia risk and to the time required for recovery to normothermia.

CONCLUSION

Admission hypothermia is common among VLBW infants and is affected by gestational age.

Care of the growth-restricted newborn

With the first 1,000 days of life proving to be a critical window of opportunity for physical and cognitive growth and development, an optimal intrauterine environment is vital. If fetus needs are compromised prenatally, there is an increased risk of intrauterine growth restriction (IUGR), and infants being born premature, low birth weight (LBW), or small-for-gestational age (SGA). Specialized care of these high-risk infants is necessary in terms of preconception interventions, resuscitation, thermoregulation, nutritional support and kangaroo mother care. Significant evidence supports exclusive breastfeeding as the standard of care for feeding SGA, preterm, LBW and very low birth weight infants. Expressed milk or donor milk may also require fortification, to meet higher nutrient needs of these newborns. Future research should address the gap in the literature on specific care of term and preterm IUGR and or SGA infants, and strengthening evidence for human milk bank models and emollient care.

Remote biomonitoring of temperatures in mothers and newborns: design, development and testing of a wearable sensor device in a tertiary-care hospital in southern India

Objective

Newer technologies such as wearables, sensors, mobile telephony and computing offer opportunities to monitor vital physiological parameters and tackle healthcare problems, thereby improving access and quality of care. We describe the design, development and testing of a wearable sensor device for remote biomonitoring of body temperatures in mothers and newborns in southern India.

Methods

Based on client needs and technological requirements, a wearable sensor device was designed and developed using principles of ‘social innovation’ design. The device underwent multiple iterations in product design and engineering based on user feedback, and then following preclinical testing, a techno-feasibility study and clinical trial were undertaken in a tertiary-care teaching hospital in Bangalore, India. Clinical trial phases I and IIa for evaluation of safety and efficacy were undertaken in the following sequence: 7 healthy adult volunteers; 18 healthy mothers; 3 healthy babies; 10 stable babies in the neonatal care intensive unit and 1 baby with morbidities. Time-stamped skin temperature readings obtained at 5 min intervals over a 1-hour period from the device secured on upper arms of mothers and abdomen of neonates were compared against readings from thermometers used routinely in clinical practice.

Results

Devices were comfortably secured on to adults and neonates, and data were efficiently transmitted via the gateway device for secure storage and retrieval for analysis. The mean skin temperatures in mothers were lower than the axillary temperatures by 2°C; and in newborns, there was a precision of –0.5°C relative to axillary measurements. While occasional minimal adverse events were noted in healthy volunteers, no adverse events were noted in mothers or neonates.

Conclusions

This proof-of-concept study shows that this device is promising in terms of feasibility, safety and accuracy (with appropriate calibration) with potential for further refinements in device accuracy and pursuit of further phases of clinical research for improved maternal and neonatal health.

Interventions to prevent hypothermia at birth in preterm and/or low birth weight infants

BACKGROUND

Newborn admission temperature is a strong predictor of outcomes across all gestations. Hypothermia immediately after birth remains a worldwide issue and, if prolonged, is associated with harm. Keeping preterm infants warm is difficult even when recommended routine thermal care guidelines are followed in the delivery room.

OBJECTIVES

To assess the efficacy and safety of interventions designed for prevention of hypothermia in preterm and/or low birth weight infants applied within 10 minutes after birth in the delivery room, compared with routine thermal care or any other single/combination of intervention(s) also designed for prevention of hypothermia in preterm and/or low birth weight infants applied within 10 minutes after birth in the delivery room.

SEARCH METHODS

We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 5), MEDLINE via PubMed (1966 to 30 June 2016), Embase (1980 to 30 June 2016), and CINAHL (1982 to 30 June 2016). We also searched clinical trials databases, conference proceedings, and reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.

SELECTION CRITERIA

Trials using randomised or quasi-randomised allocations to test interventions designed to prevent hypothermia (apart from 'routine' thermal care) applied within 10 minutes after birth in the delivery room for infants at < 37 weeks' gestation and/or birth weight ≤ 2500 grams.

DATA COLLECTION AND ANALYSIS

We used Cochrane Neonatal methods when performing data collection and analysis.

MAIN RESULTS

Twenty-five studies across 15 comparison groups met the inclusion criteria, categorised as: barriers to heat loss (18 studies); external heat sources (three studies); and combinations of interventions (four studies).Barriers to heat loss Plastic wrap or bag versus routine carePlastic wraps improved core body temperature on admission to the neonatal intensive care unit (NICU) or up to two hours after birth (mean difference (MD) 0.58°C, 95% confidence interval (CI) 0.50 to 0.66; 13 studies; 1633 infants), and fewer infants had hypothermia on admission to the NICU or up to two hours after birth (typical risk ratio (RR) 0.67, 95% CI 0.62 to 0.72; typical risk reduction (RD) -0.25, 95% CI -0.29 to -0.20; number needed to treat for an additional beneficial outcome (NNTB) 4, 95% CI 4 to 5; 10 studies; 1417 infants). Risk of hyperthermia on admission to the NICU or up to two hours after birth was increased in infants in the wrapped group (typical RR 3.91, 95% CI 2.05 to 7.44; typical RD 0.04, 95% CI 0.02 to 0.06; number needed to treat for an additional harmful outcome (NNTH) 25, 95% CI 17 to 50; 12 studies; 1523 infants), but overall, fewer infants receiving plastic wrap were outside the normothermic range (typical RR 0.75, 95% CI 0.69 to 0.81; typical RD -0.20, 95% CI -0.26 to -0.15; NNTH 5, 95% CI 4 to 7; five studies; 1048 infants).Evidence was insufficient to suggest that plastic wraps or bags significantly reduce risk of death during hospital stay or other major morbidities, with the exception of reducing risk of pulmonary haemorrhage.Evidence of practices regarding permutations on this general approach is still emerging and has been based on the findings of only one or two small studies.External heat sourcesEvidence is emerging on the efficacy of external heat sources, including skin-to-skin care (SSC) versus routine care (one study; 31 infants) and thermal mattress versus routine care (two studies; 126 infants).SSC was shown to be effective in reducing risk of hypothermia when compared with conventional incubator care for infants with birth weight ≥ 1200 and ≤ 2199 grams (RR 0.09, 95% CI 0.01 to 0.64; RD -0.56, 95% CI -0.84 to -0.27; NNTB 2, 95% CI 1 to 4). Thermal (transwarmer) mattress significantly kept infants ≤ 1500 grams warmer (MD 0.65°C, 95% CI 0.36 to 0.94) and reduced the incidence of hypothermia on admission to the NICU, with no significant difference in hyperthermia risk.Combinations of interventionsTwo studies (77 infants) compared thermal mattresses versus plastic wraps or bags for infants at ≤ 28 weeks' gestation. Investigators reported no significant differences in core body temperature nor in the incidence of hypothermia, hyperthermia, or core body temperature outside the normothermic range on admission to the NICU.Two additional studies (119 infants) compared plastic bags and thermal mattresses versus plastic bags alone for infants at < 31 weeks' gestation. Meta-analysis of these two studies showed improvement in core body temperature on admission to the NICU or up to two hours after birth, but an increase in hyperthermia. Data show no significant difference in the risk of having a core body temperature outside the normothermic range on admission to the NICU nor in the risk of other reported morbidities.

AUTHORS' CONCLUSIONS

Evidence of moderate quality shows that use of plastic wraps or bags compared with routine care led to higher temperatures on admission to NICUs with less hypothermia, particularly for extremely preterm infants. Thermal mattresses and SSC also reduced hypothermia risk when compared with routine care, but findings are based on two or fewer small studies. Caution must be taken to avoid iatrogenic hyperthermia, particularly when multiple interventions are used simultaneously. Limited evidence suggests benefit and no evidence of harm for most short-term morbidity outcomes known to be associated with hypothermia, including major brain injury, bronchopulmonary dysplasia, retinopathy of prematurity, necrotising enterocolitis, and nosocomial infection. Many observational studies have shown increased mortality among preterm hypothermic infants compared with those who maintain normothermia, yet evidence is insufficient to suggest that these interventions reduce risk of in-hospital mortality across all comparison groups. Hypothermia may be a marker for illness and poorer outcomes by association rather than by causality. Limitations of this review include small numbers of identified studies; small sample sizes; and variations in methods and definitions used for hypothermia, hyperthermia, normothermia, routine care, and morbidity, along with lack of power to detect effects on morbidity and mortality across most comparison groups. Future studies should: be adequately powered to detect rarer outcomes; apply standardised morbidity definitions; focus on longer-term outcomes, particularly neurodevelopmental outcomes.

Perinatal outcomes following Helping Babies Breathe training and regular peer-peer skills practice among village midwives in Sudan

BACKGROUND

Over 80% of deliveries in Sudan occur in rural areas, attended by village midwives (VMWs).

OBJECTIVE

To determine the impact of Helping Babies Breathe training and regular peer-peer skills practice (HBBT^+RPPSP) on VMW resuscitation practices and outcomes.

METHODS

In a prospective community-based intervention study, 71/82 VMWs, reporting to six East Nile rural medical centres, with previous experience in community health research, consented to HBBT^+RPPSP. Outcomes included changes in the resuscitation practices, fresh stillbirths (FSB) and early neonatal deaths <1 week (ENND).

RESULTS

There were 1350 and 3040 deliveries before and after HBBT^+RPPSP, respectively, with no significant differences between the two cohorts regarding maternal age, education or area of birth. Drying of the newborn increased almost tenfold (8.4%, n=113 to 74.9%, n=1011) while suctioning of the mouth/nose decreased fivefold (80.3%, n=2442 to 14.4%, n=437) following HBBT^+RPPSP. Pre-HBBT^+RPPSP9/18 (50%) newborns who had mouth-to-mouth ventilation died, compared with 13/119 (11%) who received bag-mask ventilation post-HBBT^+RPPSP. Excluding 11 macerated fetuses, there were 55 perinatal deaths: 14 FSB/18 ENND (6 months pre-HBBT^+RPPSP) and 10 FSB/13 ENND (18 months post-HBBT^+RPPSP). FSB rates decreased from 10.5 to 3.3 per 1000 births ((χ²)=8.6209, p=0.003), while ENND rates decreased from 13.5 to 4.3 per 1000 live births ((χ²)=10.9369, p=0.001) pre-HBBT^+RPPSP and post-HBBT^+RPPSP, respectively.

CONCLUSION

In a selected group of VMWs, HBBT^+RPPSP was associated with improvements in newborn resuscitation and perinatal outcomes. HBBT^+RPPSP could have immense benefits if propagated nationally to all 17 000 VMWs in Sudan.

Market mechanisms for newborn health in Nepal

Background

In Nepal, hypothermia is a major risk factor for newborn survival, but the country’s public health care sector has insufficient capacity to improve newborn survival given the burden imposed by distance to health facilities and cost. Low-cost technology to provide newborn thermal care in resource-limited environments exists, but lacks effective distribution channels.

This study aims to develop a private sector distribution model for dedicated newborn thermal care technology to ensure equitable access to thermal protection and ultimately improve newborn health in Nepal.

Methods

We conducted a document analysis of newborn health policy in Nepal and a scoping literature review of approaches to newborn hypothermia in the region, followed by qualitative interviews with key stakeholders of newborn health in Nepal.

Results

Current solutions addressing newborn hypothermia range from high-technology, high-cost incubators to low-cost behavioral interventions such as skin-to-skin care. However, none of these interventions  are currently implemented at scale. A distribution model that provides incentives for community health volunteers and existing public health services in Nepal can deliver existing low-cost infant warmers to disadvantaged mothers where and when needed. Newborn technology can serve as an adjunct to skin-to-skin care and potentially create demand for newborn care practices.

Conclusion

Harnessing market forces could promote public health by raising awareness of newborn challenges, such as newborn hypothermia, and triggering demand for appropriate health technology and related health promotion behaviors. Market approaches to promoting public health have been somewhat neglected, especially in economically disadvantaged and vulnerable populations, and deserve greater attention in Nepal and other settings with limited public health service delivery capacity.

Differences in Temperature Changes in Premature Infants During Invasive Procedures in Incubators and Radiant Warmers

Premature infants tend to lose heat quickly. This loss can be aggravated when they have received an invasive procedure involving a venous puncture. This research uses crossover design by conducting 2 intervention tests to compare 2 different treatments on the same sample. This research involved 2 groups with 18 premature infants in each. The process of data analysis used a statistical independent t test. Interventions conducted in an open incubator showed a p value of .001 which statistically related to heat loss in premature infants. In contrast, the radiant warmer p value of .001 statistically referred to a different range of heat gain before and after the venous puncture was given. The radiant warmer saved the premature infant from hypothermia during the invasive procedure. However, it is inadvisable for routine care of newborn infants since it can increase insensible water loss.

Reducing hypothermia in newborns admitted to a neonatal care unit in a large academic hospital in New Delhi, India

Neonatal hypothermia is a common and dangerous condition around the world. 70% of neonates born in Kalawati Saran Children’s Hospital in New Delhi, India, and subsequently admitted to the neonatal intensive care unit (NICU) had a temperature below 36.5°C on admission. In July 2016, we formed a team of staff from the labour room, NICU and auxiliary staff to reduce hypothermia in babies transported to our NICU using quality improvement methods. We identified problems related to staff awareness of hypothermia and its dangers, environmental factors and supply issues in the labour room, and challenges with rapidly and safely transferring sick newborns to the NICU. We used the Plan-Do-Study-Act cycles to test and adapt solutions to these problems. Because infection is a common complication of hypothermia, we also instituted a training programme to improve handwashing skills among parents and health workers. Within 9 months of starting our quality improvement project, the proportion of neonates who were normothermic on admission increased from 27% to 75%, the number of cases of late-onset neonatal sepsis decreased from 15.2 to 5 cases/1000 patient days, and all-cause mortality fell from 4.2 to 2.6 neonatal deaths per week. Multiple factors can lead to neonatal hypothermia, and the most important factors will differ from facility to facility. Quality improvement methods provide health workers with the skills to identify the key factors contributing to hypothermia in their facility and to develop strategies to address them. Addressing processes of care can lead to improved thermal care and save lives.

Point-of-care diagnostics to improve maternal and neonatal health in low-resource settings

Each day, approximately 830 women and 7400 newborns die from complications during pregnancy and childbirth. Improving maternal and neonatal health will require bringing rapid diagnosis and treatment to the point of care in low-resource settings. However, to date there are few diagnostic tools available that can be used at the point of care to detect the leading causes of maternal and neonatal mortality in low-resource settings. Here we review both commercially available diagnostics and technologies that are currently in development to detect the leading causes of maternal and neonatal mortality, highlighting key gaps in development where innovative design could increase access to technology and enable rapid diagnosis at the bedside.

Polyethylene versus cotton cap as an adjunct to body wrap in preterm infants

BACKGROUND

Occlusive body wrap using polyethylene plastic applied immediately after birth had been shown to reduce hypothermia among preterm infants. Various adjunct methods have been studied in an attempt to further reduce the incidence of hypothermia. This study was conducted to determine whether polyethylene cap is more effective than cotton cap as an adjunct to polyethylene occlusive body wrap in reducing hypothermia in preterm infants.

METHODS

The subjects consisted of preterm infants 24-34 weeks' gestation born at Universiti Kebangsaan Malaysia Medical Centre. Infants were randomly assigned to NeoCap or control groups. Infants in both groups were wrapped in polyethylene sheets from the neck downwards immediately after birth without prior drying. Infants in the control group had their heads dried and subsequently covered with cotton caps while infants in the NeoCap group had polyethylene caps put on without drying. Axillary temperature was measured on admission to the neonatal intensive care unit (NICU), and after having been stabilized in the incubator.

RESULTS

Among the 80 infants recruited, admission hypothermia (axillary temperature <36.5°C) was present in 37 (92.5%) and in 40 (100%) in the NeoCap and control groups, respectively. There was no significant difference in mean temperature on NICU admission between the two groups (35.3 vs 35.1°C, P = 0.36). Mean post-stabilization temperature, however, was significantly higher in the NeoCap group (36.0 vs 35.5°C, P = 0.01).

CONCLUSION

Combined use of polyethylene body wrap and polyethylene cap was associated with a significantly higher mean post-stabilization temperature compared with polyethylene body wrap and cotton cap.

The impact of mobile phone based messages on maternal and child healthcare behaviour: a retrospective cross-sectional survey in Bangladesh

BACKGROUND

Mobile phones are gradually becoming an integral part of healthcare services worldwide. We assessed the association between Aponjon mobile phone based messaging services and practices regarding childbirth and care of mother and neonates in selected areas in Bangladesh.

METHODS

In early 2014, 476 subscriber mothers whose last born child's age was between 3 and 18 months, were recruited to the study by Dnet from selected areas of Bangladesh. One group of mothers received the early warning messages from Aponjon during pregnancy (exposed; n = 210) while the other group of new mothers did not receive the messages during pregnancy as they had enrolled in the service after childbirth (non-exposed; n = 266). We undertook regression analyses to investigate the relationship between timing of exposure to Aponjon messages and socio-economic factors and outcomes of safe delivery, immediate breastfeeding post birth, delayed bathing of the neonate, and number of postnatal care (PNC) visits.

RESULTS

Women reported delivering babies at home without a skilled birth attendant (SBA) (n = 58, 12%), at home with SBA (n = 111, 23%) and at health facilities (n = 307, 65%). Most (n = 443, 93%) women breastfed babies immediately post birth. Babies were bathed after 72 h (n = 294, 62%), between 48 and 72 (n = 100, 21%) and between 0 and 47 (n = 80, 17%) hours after birth. PNC frequencies were reported as none (n = 273, 57%), 1 (n = 79, 17%), 2 (n = 54, 11%), 3 (n = 34, 7%) and 4 (n = 36, 8%). There was no significant association between exposure to Aponjon messages during pregnancy and presence of a SBA at birth, breastfeeding practices, and postnatal care visits, although delayed bathing up to 48 h was significant at the 10% but not 5% level (RRR 1.7; 95% CI 0.93-3.0; p = 0.083). Women with higher education, from higher income, older in age, with birth order 1 or 2 were more likely to birth at health facilities. Facility based delivery was an independent factor for delayed bathing and having postnatal care visits.

CONCLUSIONS

Low cost mobile phone messages may have the potential to positively influence maternal and child healthcare behaviours, such as delayed timing of first bath, in resource-poor settings. Further studies are needed, with adequate sample size to detect significant change.

Where technology does not go: specialised neonatal care in resource-poor and conflict-affected contexts

Setting: Although neonatal mortality is gradually decreasing worldwide, 98% of neonatal deaths occur in low- and middle-income countries, where hospital care for sick and premature neonates is often unavailable. Médecins Sans Frontières Operational Centre Brussels (MSF-OCB) managed eight specialised neonatal care units (SNCUs) at district level in low-resource and conflict-affected settings in seven countries. Objective: To assess the performance of the MSF SNCU model across different settings in Africa and Southern Asia, and to describe the set-up of eight SNCUs, neonate characteristics and clinical outcomes among neonates from 2012 to 2015. Design: Multicentric descriptive study. Results: The MSF SNCU model was characterised by an absence of high-tech equipment and an emphasis on dedicated nursing and medical care. Focus was on the management of hypothermia, hypoglycaemia, feeding support and early identification/treatment of infection. Overall, 11 970 neonates were admitted, 41% of whom had low birthweight (<2500 g). The main diagnoses were low birthweight, asphyxia and neonatal infections. Overall mortality was 17%, with consistency across the sites. Chances of survival increased with higher birthweight. Conclusion: The standardised SNCU model was implemented across different contexts and showed in-patient outcomes within acceptable limits. Low-tech medical care for sick and premature neonates can and should be implemented at district hospital level in low-resource settings.

Sociocultural factors affecting uptake of home-based neonatal thermal care practices in Africa: A qualitative review

Neonatal hypothermia is a major contributor to neonatal mortality in sub-Saharan Africa, often as a comorbidity of severe infections, preterm births or asphyxia. Simple, cost-effective thermal care practices (TCPs) immediately at birth and in the post-natal period are recommended in the World Health Organization 'warm chain'. Current practices are suboptimal in the home in low-resource settings, where approximately half of neonatal deaths occur. Several databases (PubMed, OVID SP, Web of Science, The Cochrane Library and Google Scholar) were searched for original research on home-based TCPs. Seventeen articles were identified, and the results were analysed using a 'thermal care behavioural model'. This review of the qualitative literature on home-based practices across Africa illuminates the sociocultural factors affecting the uptake of recommended practices and strategies for behaviour change. Findings from the review confirm that potentially harmful cultural norms and traditions influence the sequence of TCPs in different contexts across Africa. Furthermore, caregiver factors and contextual barriers or facilitating factors to TCPs and behaviour change exist. Hypothermia and home-based TCPs are areas for further research. Thermal care behaviour change interventions tailored to the sociocultural context are necessary to improve neonatal outcomes in Africa.

Advances in understanding and management of retinopathy of prematurity

The understanding, diagnosis, and treatment of retinopathy of prematurity have changed in the 70 years since the original description of retrolental fibroplasia associated with high oxygenation. It is now recognized that retinopathy of prematurity differs in appearance worldwide and as ever smaller and younger premature infants survive. New methods are being evaluated to image the retina, diagnose severe retinopathy of prematurity, and determine windows of time for treatment to save eyes and improve visual and neural outcomes. New treatments to promote physiologic retinal vascular development, vascular repair, and inhibit vasoproliferation by regulating proteins involved in vascular endothelial growth factor, insulin-like growth factor, or erythropoietin signaling. Reducing excessive oxidative/nitrosative stress and understanding progenitor cells and neurovascular and glial vascular interactions are being studied.

Golden 60 minutes of newborn's life: Part 2: Term neonate

The concept of "Golden 60 minutes" or "Golden Hour" has been derived from adult trauma. It has been defined as the first 60 min of postnatal life. It has been seen that care received by any newborn in the initial first hour has implications in the future life, showing the importance of golden hour. The major cause of neonatal mortality term newborn is asphyxia, which can be reduced with effective resuscitation. In golden hour approach for term newborn, the importance is given to effective and evidence based resuscitation, post-resuscitation care, delayed cord clamping, prevention of hypothermia, immediate breast feeding, prevention of hypoglycemia, and starting of therapeutic hypothermia in case of moderate to severe asphyxia. In this part of review, we will cover all the golden hour interventions in term neonate with current evidence.

A New Look at Care in Pregnancy: Simple, Effective Interventions for Neglected Populations

BACKGROUND

Although this is beginning to change, the content of antenatal care has been relatively neglected in safe-motherhood program efforts. This appears in part to be due to an unwarranted belief that interventions over this period have far less impact than those provided around the time of birth. In this par, we review available evidence for 21 interventions potentially deliverable during pregnancy at high coverage to neglected populations in low income countries, with regard to effectiveness in reducing risk of: maternal mortality, newborn mortality, stillbirth, prematurity and intrauterine growth restriction. Selection was restricted to interventions that can be provided by non-professional health auxiliaries and not requiring laboratory support.

METHODS

In this narrative review, we included relevant Cochrane and other systematic reviews and did comprehensive bibliographic searches. Inclusion criteria varied by intervention; where available randomized controlled trial evidence was insufficient, observational study evidence was considered. For each intervention we focused on overall contribution to our outcomes of interest, across varying epidemiologies.

RESULTS

In the aggregate, achieving high effective coverage for this set of interventions would very substantially reduce risk for our outcomes of interest and reduce outcome inequities. Certain specific interventions, if pushed to high coverage have significant potential impact across many settings. For example, reliable detection of pre-eclampsia followed by timely delivery could prevent up to ¼ of newborn and stillbirth deaths and over 90% of maternal eclampsia/pre-eclampsia deaths. Other interventions have potent effects in specific settings: in areas of high P falciparum burden, systematic use of insecticide-treated nets and/or intermittent presumptive therapy in pregnancy could reduce maternal mortality by up to 10%, newborn mortality by up to 20%, and stillbirths by up to 25-30%. Behavioral interventions targeting practices at birth and in the hours that follow can have substantial impact in settings where many births happen at home: in such circumstances early initiation of breastfeeding can reduce risk of newborn death by up to 20%; good thermal care practices can reduce mortality risk by a similar order of magnitude.

CONCLUSIONS

Simple interventions delivered during pregnancy have considerable potential impact on important mortality outcomes. More programmatic effort is warranted to ensure high effective coverage.

Efficacy and Safety of Plastic Wrap for Prevention of Hypothermia after Birth and during NICU in Preterm Infants: A Systematic Review and Meta-Analysis

OBJECTIVE

This meta-analysis aimed to investigate the efficacy and safety of plastic wrap applied after birth and during NICU in preterm infants for prevention of heat loss in preterm infants.

STUDY METHODS

The Medline (1950 to August 2015), the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 7, 2015), CINAHL (1982 to August 2015) and the Embase (1974 to August 2015) databases were searched for randomized controlled trials (RCTs) or quasi-RCTs with main outcomes related to the core temperature (baseline temperature and/or post-stabilization temperature), hypothermia, mortality rate and hyperthermia.

RESULT

The included studies were of low to moderate quality. Compared with unwrapped infants, plastic wrap was associated with a significantly higher baseline temperature and post-stabilization temperature both in infants < 28 weeks of gestation (mean difference [MD] = 0.62, 95% CI 0.38 to 0.85; MD = 0.41, 95% CI 0.33 to 0.50, respectively), and in infants between 28 to 34 weeks of gestation (MD = 0.54, 95% CI 0.21 to 0.87; MD = 0.64, 95% CI 0.45 to 0.82, respectively). Use of plastic wrap was associated with lower incidence of hypothermia (relative risk [RR] = 0.70, 95% CI 0.63 to 0.78). However, use of plastic wrap in preterm infants was not associated with decrease in mortality (RR: 0.88, 95% CI 0.70 to 1.12, P = 0.31). Incidence of hyperthermia was significantly higher in the plastic wrap group as compared to that in the control group (RR = 2.55, 95% CI: 1.56 to 4.15, P = 0.0002). Hyperthermia in the plastic wrap group was resolved within one or two hours after unwrapping the babies.

CONCLUSION

Plastic wrap can be considered an effective and safe additional intervention to prevent hypothermia in preterm infants. However, its cost-effectiveness and long-term effect on mortality needs to be ascertained by conducting well-designed studies with longer follow-up period.

The effect of coverings, including plastic bags and wraps, on mortality and morbidity in preterm and full-term neonates

Neonatal hypothermia is an important risk factor for mortality and morbidity, and is common even in temperate climates. We conducted a systematic review to determine whether plastic coverings, used immediately following delivery, were effective in reducing the incidence of mortality, hypothermia and morbidity. A total of 26 studies (2271 preterm and 1003 term neonates) were included. Meta-analyses were conducted as appropriate. Plastic wraps were associated with a reduction in hypothermia in preterm (⩽29 weeks; risk ratio (RR)=0.57; 95% confidence interval (CI) 0.46 to 0.71) and term neonates (RR=0.76; 95% CI 0.60 to 0.96). No significant reduction in neonatal mortality or morbidity was found; however, the studies were underpowered for these outcomes. For neonates, especially preterm, plastic wraps combined with other environmental heat sources are effective in reducing hypothermia during stabilization and transfer within hospital. Further research is needed to quantify the effects on mortality or morbidity, and investigate the use of plastic coverings outside hospital settings or without additional heat sources.

What impact do essential newborn care practices have on neonatal mortality in low and lower-middle income countries? Evidence from Bangladesh

OBJECTIVE

To assess the impact of essential newborn care (ENC) practices on the mortality of neonates delivered at home in Bangladesh.

STUDY DESIGN

This study used cross-sectional data from the 2011 Bangladesh Demographic and Health Survey. Adjusted logistic regression model was used to examine the effect of ENC practices on neonatal mortality based on 3190 live-born infants.

RESULT

Delayed bathing (72 h after delivery) significantly contributed to reducing neonatal mortality. A significant but counterintuitive relation was observed between the dry cord care and neonatal deaths.

CONCLUSION

Neonatal mortality may be reduced through emphasizing delayed bathing. Specific guidelines on the cleanliness of the fabric used to dry and wrap newborns, as well as emphasizing the use of clean delivery kits and initiation of immediate and exclusive breastfeeding, may improve neonatal outcomes. Further, the ENC guidelines in Bangladesh should include the application of topical antiseptics to the cord stump.

Reducing Transitional Hypothermia in Outborn Very Low Birth Weight Infants

BACKGROUND

Transitional hypothermia (TH) is associated with increased morbidity and mortality in very low birth weight (VLBW) infants worldwide.

OBJECTIVES

To assess the effect of a quality improvement project (QIP) on outborn TH and the associated mortality/morbidity among VLBW neonates.

METHODS

We conducted a multi-intervention QIP to reduce TH (<36°C) among outborn VLBW neonates. This cohort study compared a historical group (group I, n = 86) to a prospective group (group II, established after QIP implementation, n = 86). The primary outcome was axillary temperature measured in the delivery room (DR) and upon admission to the neonatal intensive care unit (NICU).

RESULTS

The baseline characteristics of the two groups were similar. After introducing the QIP, the mean DR and NICU admission temperatures of the patients rose from 35.5 to 36.1°C and from 34.6 to 36.2°C, respectively (p < 0.01), and the percentage of patients with temperatures <36°C in the DR and NICU decreased from 80 to 40% and from 81 to 42% (p < 0.01), respectively. Meanwhile, the percentage of patients with a normal temperature in the DR and NICU rose from 20 to 58% and from 19 to 56% (p < 0.01), respectively, which was accompanied by significantly decreased mortality (p < 0.02) and other improvements.

CONCLUSION

Implementation of a QIP resulted in a decrease in the number of moderately hypothermic VLBW neonates and a sustained improvement in normothermia rates during DR stabilization and transfer to the NICU in outborn VLBW neonates.

"Why not bathe the baby today?": A qualitative study of thermal care beliefs and practices in four African sites

Background

Recommendations for care in the first week of a newborn’s life include thermal care practices such as drying and wrapping, skin to skin contact, immediate breastfeeding and delayed bathing. This paper examines beliefs and practices related to neonatal thermal care in three African countries.

Methods

Data were collected in the same way in each site and included 16–20 narrative interviews with recent mothers, eight observations of neonatal bathing, and in-depth interviews with 12–16 mothers, 9–12 grandmothers, eight health workers and 0–12 birth attendants in each site.

Results

We found similarities across sites in relation to understanding the importance of warmth, a lack of opportunities for skin to skin care, beliefs about the importance of several baths per day and beliefs that the Vernix caseosa was related to poor maternal behaviours. There was variation between sites in beliefs and practices around wrapping and drying after delivery, and the timing of the first bath with recent behavior change in some sites. There was near universal early bathing of babies in both Nigerian sites. This was linked to a deep-rooted belief about body odour. When asked about keeping the baby warm, respondents across the sites rarely mentioned recommended thermal care practices, suggesting that these are not perceived as salient.

Conclusion

More effort is needed to promote appropriate thermal care practices both in facilities and at home. Programmers should be aware that changing deep rooted practices, such as early bathing in Nigeria, may take time and should utilize the current beliefs in the importance of neonatal warmth to facilitate behaviour change.

Vitamin paradox in obesity: Deficiency or excess?

Since synthetic vitamins were used to fortify food and as supplements in the late 1930s, vitamin intake has significantly increased. This has been accompanied by an increased prevalence of obesity, a condition associated with diabetes, hypertension, cardiovascular disease, asthma and cancer. Paradoxically, obesity is often associated with low levels of fasting serum vitamins, such as folate and vitamin D. Recent studies on folic acid fortification have revealed another paradoxical phenomenon: obesity exhibits low fasting serum but high erythrocyte folate concentrations, with high levels of serum folate oxidation products. High erythrocyte folate status is known to reflect long-term excess folic acid intake, while increased folate oxidation products suggest an increased folate degradation because obesity shows an increased activity of cytochrome P450 2E1, a monooxygenase enzyme that can use folic acid as a substrate. There is also evidence that obesity increases niacin degradation, manifested by increased activity/expression of niacin-degrading enzymes and high levels of niacin metabolites. Moreover, obesity most commonly occurs in those with a low excretory reserve capacity (e.g., due to low birth weight/preterm birth) and/or a low sweat gland activity (black race and physical inactivity). These lines of evidence raise the possibility that low fasting serum vitamin status in obesity may be a compensatory response to chronic excess vitamin intake, rather than vitamin deficiency, and that obesity could be one of the manifestations of chronic vitamin poisoning. In this article, we discuss vitamin paradox in obesity from the perspective of vitamin homeostasis.

Neonatal admissions, quality of care and outcome: 4 years of inpatient audit data from The Gambia's teaching hospital

BACKGROUND

National facility-based neonatal mortality audits are an important source of data to identify areas for improvement of service delivery and outcome of care.

OBJECTIVES

To examine admissions to the neonatal unit, Edward Francis Small Teaching Hospital, Banjul, The Gambia and make recommendations for programme action to reduce mortality through improvements in the quality of care, particularly with respect to suspected neonatal infections.

METHODS

Case notes were reviewed for all neonates admitted to the neonatal unit during a 5-year period (1 January 2009 to 31 December 2013) to assess outcome and quality of care. Data for 2009 were subsequently excluded because of the low proportion of records retrieved.

RESULTS

Of the 4944 admissions between 1 January 2010 and 31 December 2013, 1734 infants (35%) died, with 57% of all deaths occurring within the first 48 hours of admission. There were 1267 early neonatal deaths (deaths occurring during the first 7 days of life), 67% of which occurred during the first 48 hours of life. Independent predictors of neonatal death in the multivariable analysis were; maternal lack of antenatal care, non-teaching hospital delivery, admission weight < 1500 g, abnormal blood glucose concentration ( < 2.6 mmol/L or >6.9 mmol/L) and hypothermia (axillary temperature < 36.5 ˚C). Forty-eight per cent of newborns had point-of-admission hypothermia. Possible severe bacterial infection (pSBI) accounted for 44% (2166/4944) of admissions, prematurity/low birthweight for 27% (1340/4944) and intrapartum-related conditions for 20%. Only 5% (104/2166) of pSBI cases had at least one supportive investigation; 41 had a chest radiograph, 26 had a blood culture and 43 had a lumbar puncture. Although 94% of the newborns received intravenous antibiotics, 55% of those who did lacked clinical evidence of pSBI and had no diagnostic work-up.

CONCLUSION

Priority areas for action include infection prevention and improved diagnosis and management. There is also scope to reduce hypothermia with feasible interventions particularly targeting preterm infants. Improved patient records and audit data with linked action and accountability are interventions which could prevent such deaths of newborns in The Gambia and other developing countries.

Skin, thermal and umbilical cord care practices for neonates in southern, rural Zambia: a qualitative study

BACKGROUND

In Choma District, southern Zambia, the neonatal mortality rate is approximately 40 per 1000 live births and, although the rate is decreasing, many deliveries take place outside of formal facilities. Understanding local practices during the postnatal period is essential for optimizing newborn care programs.

METHODS

We conducted 36 in-depth interviews, five focus groups and eight observational sessions with recently-delivered women, traditional birth attendants, and clinic and hospital staff from three sites, focusing on skin, thermal and cord care practices for newborns in the home.

RESULTS

Newborns were generally kept warm by application of hats and layers of clothing. While thermal protection is provided for preterm and small newborns, the practice of nighttime bathing with cold water was common. The vernix was considered important for the preterm newborn but dangerous for HIV-exposed infants. Mothers applied various substances to the skin and umbilical cord, with special practices for preterm infants. Applied substances included petroleum jelly, commercial baby lotion, cooking oil and breastmilk. The most common substances applied to the umbilical cord were powders made of roots, burnt gourds or ash. To ward off malevolent spirits, similar powders were reportedly placed directly into dermal incisions, especially in ill children.

CONCLUSIONS

Thermal care for newborns is commonly practiced but co-exists with harmful practices. Locally appropriate behavior change interventions should aim to promote chlorhexidine in place of commonly-reported application of harmful substances to the skin and umbilical cord, reduce bathing of newborns at night, and address the immediate bathing of HIV-infected newborns.

Keeping babies warm: a non-inferiority trial of a conductive thermal mattress

BACKGROUND

External thermal support is critical for preterm or ill infants due to altered thermoregulation. Incubators are the gold standard for long-term support and have been adopted successfully in many countries. Alternatives such as radiant warmers, blankets and others are often used as standard of care (SoC) in resource-limited settings when infants are otherwise not in Kangaroo Mother Care (KMC).

METHODS

In this pilot study, we evaluate the feasibility of a conductive thermal mattress (CTM) using phase change materials as a low-cost warmer. We conducted a prospective multicentre open-label randomised controlled trial to determine non-inferiority of this CTM to SoC warming practices in low birthweight infants. The primary outcome was maintenance of axillary temperature.

RESULTS

We equally randomised 160 infants to CTM or SoC. The latter cohort continued to receive warmth by radiant warmers (n=48), blankets (n=18), warmed cradles (n=7) or KMC (n=7) before, during and subsequent to the study. CTM was deemed non-inferior since warmed babies had higher axillary temperature compared with SoC (mean increase 0.11±0.03°C SEM; p<0.001). Post hoc comparison to radiant warmers alone showed that CTM led to a higher axillary temperature (mean increase by 0.14±0.03°C SEM; p<0.001).

CONCLUSIONS

Short-term use of CTM compared with radiant warmers and other modes of warming is non-inferior to SoC and efficacious in maintaining body temperature. No adverse effects were reported. An extended multinational trial, preferably one that demonstrates longer-term thermoregulation, is warranted.

Developing sustainable global health technologies: insight from an initiative to address neonatal hypothermia

Relative to drugs, diagnostics, and vaccines, efforts to develop other global health technologies, such as medical devices, are limited and often focus on the short-term goal of prototype development instead of the long-term goal of a sustainable business model. To develop a medical device to address neonatal hypothermia for use in resource-limited settings, we turned to principles of design theory: (1) define the problem with consideration of appropriate integration into relevant health policies, (2) identify the users of the technology and the scenarios in which the technology would be used, and (3) use a highly iterative product design and development process that incorporates the perspective of the user of the technology at the outset and addresses scalability. In contrast to our initial idea, to create a single device, the process guided us to create two separate devices, both strikingly different from current solutions. We offer insights from our initial experience that may be helpful to others engaging in global health technology development.

Usage of EMBRACE(TM) in Gujarat, India: Survey of Paediatricians

Aim. EMBRACE(TM) is an innovative, low cost infant warmer for use in neonates. It contains phase change material, which stays at constant temperature for 6 hours. We surveyed paediatricians using EMBRACE(TM) regarding benefits, risks, and setup in which it was used in Gujarat. Methods. Questionnaire was administered telephonically to 52 out of 53 paediatricians. Results. EMBRACE(TM) was used for an average of 8.27 (range of 3-18, SD = 3.84) months by paediatricians. All used it for thermoregulation during transfers, for average (SD) duration of 42 (0.64) m per transfer, 62.7% used it at mother's side for average (SD) 11.06 (7.89) h per day, and 3.9% prescribed it at home. It was used in low birth weight neonates only by 56.9% while 43.1% used it for all neonates. While hyperthermia was not reported, 5.9% felt that EMBRACE(TM) did not prevent hypothermia. About 54.9% felt that they could not monitor the newborn during EMBRACE(TM) use. Of paediatricians who practiced kangaroo mother care (KMC), 7.7% have limited/stopped/decreased the practice of KMC and substituted it with EMBRACE(TM). Conclusions. EMBRACE(TM) was acceptable to most but concerns related to monitoring neonates and disinfection remained. Most paediatricians felt that it did not hamper KMC practice.

Newborn care practices in rural Bangladesh: Implications for the adaptation of kangaroo mother care for community-based interventions

Bangladesh has one of the world's highest rates of low birth weight along with prevalent traditional care practices that leave newborns highly vulnerable to hypothermia, infection, and early death. We conducted formative research to explore existing newborn care practices in rural Bangladesh with an emphasis on thermal protection, and to identify potential facilitators, barriers, and recommendations for the community level delivery of kangaroo mother care (CKMC). Forty in-depth interviews and 14 focus group discussions were conducted between September and December 2012. Participants included pregnant women and mothers, husbands, maternal and paternal grandmothers, traditional birth attendants, village doctors, traditional healers, pharmacy men, religious leaders, community leaders, and formal healthcare providers. Audio recordings were transcribed and translated into English, and the textual data were analyzed using the Framework Approach. We find that harmful newborn care practices, such as delayed wrapping and early initiation of bathing, are changing as more biomedical advice from formal healthcare providers is reaching the community through word-of-mouth and television campaigns. While the goal of CKMC was relatively easily understood and accepted by many of the participants, logistical and to a lesser extent ideological barriers exist that may keep the practice from being adopted easily. Women feel a sense of inevitable responsibility for household duties despite the desire to provide the best care for their new babies. Our findings showed that participants appreciated CKMC as an appropriate treatment method for ill babies, but were less accepting of it as a protective method of caring for seemingly healthy newborns during the first few days of life. Participants highlighted the necessity of receiving help from family members and witnessing other women performing CKMC with positive outcomes if they are to adopt the behavior themselves. Focusing intervention messages on building a supportive environment for CKMC practice will be critical for the intervention's success.

Viral respiratory tract infections in the neonatal intensive care unit: the VIRIoN-I study

OBJECTIVE

To determine the frequency of respiratory viral infections among infants who were evaluated for late-onset sepsis in the neonatal intensive care units (NICUs) of Parkland Memorial Hospital, Dallas, Texas; and Women & Infants Hospital, Providence, Rhode Island.

STUDY DESIGN

Prospective cohort study conducted from January 15, 2012 to January 31, 2013. Infants in the NICU were enrolled if they were inborn, had never been discharged home, and were evaluated for sepsis (at >72 hours of age) and antibiotic therapy was initiated. Infants had a nasopharyngeal specimen collected for detection of respiratory viruses by multiplex polymerase chain reaction within 72 hours of the initiation of antibiotic therapy. Their medical records were reviewed for demographic, clinical, radiographic, and laboratory data until NICU discharge.

RESULTS

During the 13-month study, 8 of 100 infants, or 8 (6%) of the 135 sepsis evaluations, had a respiratory virus detected by polymerase chain reaction (2, enterovirus/rhinovirus; 2, rhinovirus; 2, coronaviruses; and 2, parainfluenza-3 virus). By bivariate analysis, the infants with viral detection were older (41 vs 11 days; P = .007), exposed to individuals with respiratory tract viral symptoms (37% vs 2%; P = .003), tested for respiratory viruses by provider (75% vs 11%; P < .001), and had lower total neutrophil counts (P = .02). In multivariate regression analysis, the best predictor of viral infection was the caregivers' clinical suspicion of viral infection (P = .006).

CONCLUSIONS

A total of 8% of infants, or 6% of all NICU sepsis evaluations, had a respiratory virus detected when evaluated for bacterial sepsis. These findings argue for more respiratory viral testing of infants with suspected sepsis using optimal molecular assays to establish accurate diagnoses, prevent transmission, and inform antibiotic stewardship efforts.

Does cultural practice affects neonatal survival- a case control study among low birth weight babies in Aceh Province, Indonesia

BACKGROUND

Cultural practice have often overlooked when providing maternal and child health care services. Low birth weight is the second cause of neonatal mortality in the world but it is a major factor in a developing country such as Indonesia. The purpose of this study is to predict the neonatal mortality among low birth weight babies in Aceh Province Indonesia.

METHODS

Unmatched case control study was conducted using data from year 2010 to 2012 in 8 selected districts of Aceh Province Indonesia. A total of 500 samples were obtained. There were 250 of the samples died in neonatal period (case group) and 250 who were alive (control group). There were 26 variables studied and were grouped into 4 factors: neonatal factor, maternal factor, maternal and child health services and neonatal care practices. The data was analysed using bivariate logistic regression and multivariate logistic regression.

RESULTS

There were 13 out of 26 variables found as determinant factors of neonatal mortality among low birth weight babies in Aceh Province. The predictors found in this study were: boy (aOR1.80, 95% CI: 1.09-2.96), moderate low birth weight (aOR17.84, 95% CI: 6.20-51.35), preterm (aOR1.84, 95% CI: 1.07- 3.17), presence of maternal illnesses (aOR1.87, 95% CI: 1.06-3.30), too short or too long birth interval (aOR1.80, 95% CI: 1.20-2.91), inappropriate antenatal care (aOR2.29, 95% CI: 1.34-3.91), inappropriate neonatal visit (aOR7.04, 95% CI: 3.67-13.49), not practicing kangaroo mother care (aOR15.32, 95% CI: 2.85-82.56), not using warm bottle padding (aOR20.70, 95% CI: 6.32-67.80), not practicing 'didaring' (aOR4.33, 95% CI: 1.83-10.19), late initiation of breastfeeding (aOR2.03, 95% CI: 1.09-3.80), discard colostrums (aOR3.53, 95% CI: 1.93-6.43) and not practicing exclusive breastfeeding (aOR5.58, 95% CI: 2.89-10.77).

CONCLUSIONS

Cultural practices are strongly seen among Acehnese. Inappropriate antenatal care and neonatal care, late initiation of breastfeeding, discarding colostrums and not practicing exclusive breastfeeding were related to cultural practices. Improving knowledge heat preservation to prevent hypothermia using Kangaroo mother care, warm bottle padding and 'didaring' were proven methods to reduce neonatal mortality. Strengthening of health services in screening for high risk cases and anticipate intervention tailored to cultural practices are important to decrease neonatal mortality among low birth weight.

Neonatal hypothermia and associated risk factors at baby friendly hospital in babol, iran

Background:

Thermal care is an important element of Baby Friendly Hospital.

Aim:

The objective of this study was to determine the prevalence of neonatal hypothermia and associated risk factors in healthy full term newborns at a Baby Friendly Hospital.

Subjects and Methods:

A cross-sectional, descriptive study was conducted on consecutively healthy full term neonates recruited during a 1 year. Temperatures were recorded immediately after birth and at the age of 1, 2 and 4 h after birth in order to estimate the prevalence of neonatal hypothermia, defined as axillary temperature less than 36.0°C. The data were collected using an especially questionnaire; data of history of abortion, parity, mode of vaginal delivery, gestational age, birth weight, newborn temperatures, time of the first skin-to-skin contact, time of first breast feeding, first wrapping and first visiting by the pediatrician. Association between neonatal hypothermia and risk factors was determined using logistic regression.

Results:

Axillary temperature showed 41.2%, 47.5%, 46.4% and 37.2% of the a consecutive number of 522 healthy full term neonates were moderately hypothermia immediately after birth, at 1 h, 2 h and 4 h respectively. Spontaneous labor and warming room were associated with decreased risk of hypothermia. A persistently high prevalence of neonatal hypothermia was shown within the first 4 h of vaginal birth. All analyses were carried out using the SPSS version 17.0 (Chicago IL, USA). Test of the associations were done, stepwise multiple logistic regressions. Odds ratios (ORs) were assessed using maximum likelihood and associated 95% confidence intervals were computed. A P ≤ 0.05 was considered to be statistically significant

Conclusion:

The findings of this study indicated that a high prevalence of neonatal hypothermia was identified among healthy full term newborn in a Baby Friendly Hospital Initiative. Therefore, it is necessary to emphasize on the development “warm chain” in preventing neonatal hypothermia in Baby Friendly Hospital.

Thermal care for newborn babies in rural southern Tanzania: a mixed-method study of barriers, facilitators and potential for behaviour change

BACKGROUND

Hypothermia contributes to neonatal morbidity and mortality in low-income countries, yet little is known about thermal care practices in rural African settings. We assessed adoption and community acceptability of recommended thermal care practices in rural Tanzania.

METHODS

A multi-method qualitative study, enhanced with survey data. For the qualitative component we triangulated birth narrative interviews with focus group discussions with mothers and traditional birth attendants. Results were then contrasted to related quantitative data. Qualitative analyses sought to identify themes linked to a) immediately drying and wrapping of the baby; b) bathing practices, including delaying for at least 6 hours and using warm water; c) day to day care such as covering the baby's head, covering the baby; and d) keeping the baby skin-to-skin. Quantitative data (n = 22,243 women) on the thermal care practices relayed by mothers who had delivered in the last year are reported accordingly.

RESULTS

42% of babies were dried and 27% wrapped within five minutes of birth mainly due to an awareness that this reduced cold. The main reason for delayed wrapping and drying was not attending to the baby until the placenta was delivered. 45% of babies born at a health facility and 19% born at home were bathed six or more hours after birth. The main reason for delayed bathing was health worker advice. The main reason for early bathing believed that the baby is dirty, particularly if the baby had an obvious vernix as this was believed to be sperm. On the other hand, keeping the baby warm and covered day-to-day was considered normal practice. Skin-to-skin care was not a normalised practice, and some respondents wondered if it might be harmful to fragile newborns.

CONCLUSION

Most thermal care behaviours needed improving. Many sub-optimal practices had cultural and symbolic origins. Drying the baby on birth was least symbolically imbued, although resisted by prioritizing of the mothers. Both practical interventions, for instance, having more than one attendant to help both mother and baby, and culturally anchored sensitization are recommended.

Risk factors and neonatal/infant mortality risk of small-for-gestational-age and preterm birth in rural Nepal

OBJECTIVE

Our study seeks to elucidate risk factors for and mortality consequences of small-for-gestational-age (SGA) and preterm birth in rural Nepal. In contrast with previous literature, we distinguish the epidemiology of SGA and preterm birth from each other.

METHODS

We analyzed data from a maternal micronutrient supplementation trial in rural Nepal (n = 4130). We estimated adjusted risk ratios (aRR) for risk factors of SGA and preterm birth, and aRRs for the associations between SGA/preterm birth and neonatal/infant mortality. We used mutually exclusive categories of term-appropriate-for-gestational-age (AGA), term-SGA, preterm-AGA, and preterm-SGA (with term-AGA as reference) in our analyses.

RESULTS

Stunted (<145 cm) and wasted (<18.5 kg/m(2)) women both had increased risk of having term-SGA (aRR 1.36, 95% CI: 1.14-1.61, aRR 1.22, 95% CI: 1.09-1.36 respectively) and preterm-SGA (aRR 2.48, 95% CI: 1.29-4.74, aRR 1.99, 95% CI: 1.33-2.97 respectively), but not preterm-AGA births. Similar results were found for low maternal weight gain per gestational week. Those born preterm-SGA generally experienced the highest neonatal and infant mortality risk, although term-SGA and preterm-AGA newborns also had statistically significantly high mortality risks compared to term-AGA babies.

CONCLUSIONS

SGA and preterm birth have distinct risk factors and mortality patterns. Maternal chronic and acute malnutrition appear to be associated with SGA outcomes. Because of high SGA prevalence in South Asia and the increased neonatal and infant mortality risk associated with SGA, there is an urgent need to intervene with effective interventions.

The incidence and prevention of hypothermia in newborn bonding after cesarean delivery: a randomized controlled trial

BACKGROUND

Little is known about thermoregulation of the newborn while bonding on the mother's chest immediately after cesarean delivery. Newborn hypothermia is associated with serious complications and should be avoided. Therefore, we evaluated whether newborns develop hypothermia during intraoperative bonding while positioned on their mothers' chests and investigated the effects of active cutaneous warming of the mothers and babies during a 20-minute intraoperative bonding period.

METHODS

We enrolled 40 parturients scheduled for elective cesarean delivery under spinal anesthesia. Mothers and their newborns were randomized to receive either passive insulation or forced-air skin-surface warming during the surgical procedure and bonding period. The primary outcome was neonatal core temperature at the end of the bonding period. Core temperatures of the newborns were measured with a rectal probe. Body temperatures of the mothers were assessed by sublingual measurements. Skin temperatures, thermal comfort of the mothers, and perioperative shivering were evaluated.

RESULTS

Without active warming from the beginning of the surgical procedure until the end of the bonding period, the mean (SD) neonatal core temperature decreased to 35.9 (0.6)°C. Seventeen of 21 (81%) newborns became hypothermic (defined as a core temperature below 36.5°C). Active skin-surface warming from the beginning of the surgical procedure until the end of the bonding period resulted in a neonatal core temperature of 37.0 (0.2)°C and a decreased incidence of hypothermia (1 of 19 (5%) newborns (P < 0.0001)). In addition, active warming increased the mean skin temperatures of the infants, maternal core and skin temperatures, maternal thermal comfort, and reduced perioperative shivering.

CONCLUSIONS

Active forced-air warming of mothers and newborns immediately after cesarean delivery reduces the incidence of infant and maternal hypothermia and maternal shivering, and increases maternal comfort.

Delivery room management of extremely low birthweight infants shows marked geographical variations in Italy

AIM

To evaluate any geographical variations in practice and adherence to international guidelines for early delivery room management of extremely low birthweight (ELBW) infants in the North, Centre and South of Italy.

METHODS

A questionnaire was sent to all 107 directors of Italian level III centres between April and August 2012.

RESULTS

There was a 92% (n = 98) response rate. A polyethylene bag/wrap was used by 54 centres (55.1%), with the highest rate in Northern Italy (77.5%) and the lowest rate in Southern (37.7%) areas. In Northern regions, one centre (2.5%) said it used oxygen concentrations >40% to initiate positive pressure ventilation in ELBW infants. These proportions were higher in the Central (14.3%) and Southern (16.2%) areas. A T-piece device for positive pressure ventilation was more frequently available in the Northern (95%) units than in those in the Central (66.7%) and Southern (69.4%) regions. A median of 13% (IQR: 5%-30%) of ELBW infants received chest compressions at birth in Italy: 5%, 18% and 22% in Northern, Central and Southern units, respectively.

CONCLUSION

In Italy, delivery room management of ELBW infants showed marked geographical variations. Implementation of national training programmes could increase adherence to the guidelines and reduce such discordance.

Medicine: a rethink? Are entrants to the profession and the way it is organised fit for purpose?

The health burden in most countries has changed. Although acute care is needed for trauma, acute illness and exacerbations of chronic disease, most of the burden is now long term. These patients need different approaches, with more emphasis upon supporting self-management, enhancing lifestyle changes, aiding compliance by shared decision-making and providing more convenient follow-up that appreciates the likelihood of multimorbidity. Integrated care will increasingly be offered from within the community. The current hospital- and doctor-centric focus needs to change to one where specialists work in the community as much as in hospitals and share this different type of care with others. For potential future doctors, the scientific basis of medicine will still underpin their unique role in diagnosis and prescribing, but they will need to understand these other changes and to be selected according to attributes compatible with their future role, and then be trained and assessed accordingly.
