Factors Influencing the Implementation of Infant Warming Devices Among Healthcare Workers in Malawian Hospitals

Objectives. Preterm infants are at risk of hypothermia. This study described the available infant warming devices (IWDs) and explored the barriers and facilitators to their implementation in neonates in Malawi. Methods. A qualitative descriptive study was conducted among 19 health care workers in Malawi from January to March 2020. All interviews were digitally recorded, transcribed, and managed using NVivo and analyzed using a thematic approach. Results. The warming devices included radiant warmers, Blantyre hot-cots, wall-mounted heaters, portable warmers, and incubators. Inadequate equipment and infrastructure and gaps in staff knowledge and capacity were reported as the main challenges to optimal IWD implementation. Caregiver acceptance was described as the main facilitator. Strategies to optimize implementation of IWD included continuous practical training and adequate availability of equipment and spare parts. Conclusion. Implementation of warming devices for the management of neonatal hypothermia is effective when there are adequate human and material resources.

Incidence and risk factors of neonatal hypothermia: A systematic review and meta-analysis

AIM

Hypothermia poses a threat to the health and lives of newborns. Therefore, it is essential to identify the factors that influence neonatal hypothermia and provide targeted intervention suggestions for clinical practice to reduce its occurrence.

METHODS

We conducted a literature search to identify factors influencing neonatal hypothermia and performed a meta-analysis to determine the prevalence of neonatal hypothermia and its associated factors. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of cohort and case-control studies, while the Agency for Healthcare Research and Quality (AHRQ) was used to evaluate the quality of cross-sectional studies.

RESULTS

Eighteen studies involving 44 532 newborns from 13 countries were included. The incidence of neonatal hypothermia was 52.5% (95% CI: 0.37, 0.68). Factors such as no skin-to-skin contact, prematurity, low birth weight, delayed breastfeeding, asphyxiation and resuscitation after birth, low APGAR score, not wearing a cap, and caesarean section were found to affect neonatal hypothermia.

CONCLUSION

Multiple factors influence neonatal hypothermia, and clinicians can utilise these factors to develop targeted intervention measures to prevent and reduce the incidence of neonatal hypothermia.

Preclinical validation of NeoWarm, a low-cost infant warmer and carrier device, to ameliorate induced hypothermia in newborn piglets as models for human neonates

Introduction

Approximately 1.5 million neonatal deaths occur among premature and small (low birthweight or small-for gestational age) neonates annually, with a disproportionate amount of this mortality occurring in low- and middle-income countries (LMICs). Hypothermia, the inability of newborns to regulate their body temperature, is common among prematurely born and small babies, and often underlies high rates of mortality in this population. In high-resource settings, incubators and radiant warmers are the gold standard for hypothermia, but this equipment is often scarce in LMICs. Kangaroo Mother Care/Skin-to-skin care (KMC/STS) is an evidence-based intervention that has been targeted for scale-up among premature and small neonates. However, KMC/STS requires hours of daily contact between a neonate and an able adult caregiver, leaving little time for the caregiver to care for themselves. To address this, we created a novel self-warming biomedical device, NeoWarm, to augment KMC/STS. The present study aimed to validate the safety and efficacy of NeoWarm.

Methods

Sixteen, 0-to-5-day-old piglets were used as an animal model due to similarities in their thermoregulatory capabilities, circulatory systems, and approximate skin composition to human neonates. The piglets were placed in an engineered cooling box to drop their core temperature below 36.5°C, the World Health Organizations definition of hypothermia for human neonates. The piglets were then warmed in NeoWarm (n = 6) or placed in the ambient 17.8°C ± 0.6°C lab environment (n = 5) as a control to assess the efficacy of NeoWarm in regulating their core body temperature.

Results

All 6 piglets placed in NeoWarm recovered from hypothermia, while none of the 5 piglets in the ambient environment recovered. The piglets warmed in NeoWarm reached a significantly higher core body temperature (39.2°C ± 0.4°C, n = 6) than the piglets that were warmed in the ambient environment (37.9°C ± 0.4°C, n = 5) (p < 0.001). No piglet in the NeoWarm group suffered signs of burns or skin abrasions.

Discussion

Our results in this pilot study indicate that NeoWarm can safely and effectively warm hypothermic piglets to a normal core body temperature and, with additional validation, shows promise for potential use among human premature and small neonates.

Introduction of a novel neonatal warming device in Malawi: an implementation science study

BACKGROUND

Neonatal hypothermia significantly contributes to infant morbidity and mortality in low-resource settings like Malawi. Kangaroo mother care (KMC) is essential but faces challenges in providing continuous thermal support. The Dream Warmer is a neonatal warming device that was developed to complement KMC. We studied its implementation outside a research environment.

METHODS

Using an implementation science approach, we conducted a prospective interventional cohort study in two hospitals and four health centres in Malawi. Through audits and surveys, we assessed the effect of the Dream Warmer on neonatal hypothermia as well as healthcare provider (HCP) and parent attitudes regarding thermoregulation and related issues.

RESULTS

The Dream Warmer raised no safety concerns and effectively treated hypothermia in 90% of uses. It was positively received by HCPs and parents, who reported it had a favourable effect on the care of small and sick newborns. Challenges identified included a scarcity of water and electricity, lack of availability of the device and HCPs forgetting to prepare it in advance of need or to use it when indicated. Feedback for future training was obtained. The Dream Warmer's strong safety and effectiveness performance is consistent with results from strict research studies. Training materials can be adapted to optimize integration into daily practice and provide educational content for parents.

CONCLUSIONS

The Dream Warmer is a safe and effective device to treat neonatal hypothermia, particularly when KMC is insufficient. We gained an understanding of how to optimize implementation through robust HCP and family education to help combat hypothermia.

Improving the Duration and Rate of Home-Based Kangaroo Mother Care: A Before-and-After Intervention Study

Introduction Kangaroo mother care (KMC) is an evidence-based, simple, time-tested, low-cost, and high-impact intervention for neonatal survival in hospitals and the community, particularly in resource-constrained areas. This has many beneficial effects on sick and stable low-birth-weight babies, lactating mothers, families, society, and the government. However, despite the World Health Organization (WHO) and United Nations International Children's Emergency Fund (UNICEF) recommendations for KMC, there is no satisfactory implementation of it in the community as well as in facilities. This study aimed to improve the duration of home-based kangaroo mother care (HBKMC). Material and methods  We conducted a before-and-after intervention hospital-based, single-center study in a level III neonatal intensive care unit (NICU) to improve the duration of HBKMC. The KMC duration was classified into four categories: short, extended, long, and continuous where KMC was provided for 4 hours/day, 5-8 hours/day, 9-12 hours/day, and more than 12 hours/day, respectively. All neonates with birth weight < 2.0 kg and their mothers/alternate KMC providers at a tertiary care hospital in India in the time period of five months from April 2021 to July 2021 were considered eligible for the study. We tested three sets of interventions by using the plan-do-study-act cycle (PDSA cycle). The first set of interventions was the sensitization of parents and healthcare workers regarding the benefits of KMC by comprehensive counseling to mothers and other family members using educational lectures, videos, charts, and posters. The second set of interventions was to reduce maternal anxiety/stress while maintaining maternal privacy by providing more female staff and teaching proper gown-wearing techniques. The third set of interventions was to solve lactation and environment temperature issues by providing antenatal and postnatal lactation counseling and warming of the nursery. The paired T-test and one-way analysis of variance (ANOVA) were used for statistical analysis, and p<0.05 was taken as significant.  Results  One hundred and eighty neonates were enrolled along with their mothers/alternate KMC providers in four phases, and three PDSA cycles were implemented. Out of 180 LBW infants, 21 (11.67%) infants received KMC < 4 hours/day. According to the KMC classification, 31% have continuous KMC in the institution, followed by 24% long KMC, 26% extended KMC, and 18% short KMC. After three PDSA cycles, HBKMC was 38.88% continuous KMC, followed by 24.22% long KMC, 20.55% extended KMC, and 16.11% short KMC. Continuous KMC was improved from 21% to 46% at the institute and 16% to 50% at home from phase 1 to phase 4 of the study after the implementation of three sets of interventions in three PDSA cycles. The phase-by-phase KMC rate and duration were improved after the application of the PDSA cycles, and this was maintained in HBKMC as well, but it was statistically not significant. Conclusion Sets of intervention packages based on needs analysis using the PDSA cycle were able to improve the rate and duration of KMC in the hospital and at home.

Association of Neonatal Hypothermia with Morbidity and Mortality in a Tertiary Hospital in Malawi

OBJECTIVES

To evaluate associations with neonatal hypothermia in a tertiary-level neonatal unit (NU) in Malawi.

METHODS

Neonates with a birth weight >1000 g were recruited and temperatures were recorded 5 min after birth, on admission and 4 h thereafter. Clinical course and outcome were reviewed. Data were analysed using Stata v.15 and p < 0.05 was considered statistically significant.

RESULTS

Between August 2018 to March 2019, 120 neonates were enrolled, and 112 were included in the data analysis. Hypothermia at 5 min after birth was noted in 74%, 77% on admission to the NU and 38% at 24 h. Neonates who had hypothermia 5 min after birth were more likely to have hypothermia on admission to the NU compared with normothermic subjects (p < 0.01). All neonates with hypothermia on admission to the NU died (100 vs.72%, p = 0.02), but hypothermia at 5 min nor at 24 h were not associated with mortality. After adjusting for potential confounders, the odds ratio of hypothermia at 5 min for hypothermia on admission to NU was 13.31 (95% CI 4.17-42.54).

DISCUSSION

A large proportion of hospitalized neonates is hypothermic on admission and has associated morbidity and mortality. Our findings suggest that a strong predictor of mortality is neonatal hypothermia on admission to the NU, and that early intervention in the immediate period after delivery could decrease the incidence of hypothermia and reduce associated morbidity and mortality.
