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.

Neonatal Admission Temperature in Middle- and High-Income Countries.

BACKGROUND AND OBJECTIVES: Despite being preventable, neonatal hypothermia remains common. We hypothesized that the proportion of newborns with hypothermia on admission would be high in all settings, higher in hospitals in middle-income countries (MIC) compared with high-income countries (HIC), and associated with morbidity and mortality. METHODS: Using the Vermont Oxford Network database of newborns with birth weights 401 to 1500 g or 22 to 29 weeks' gestational age from 2018 to 2021, we analyzed maternal and infant characteristics, delivery room management, and outcomes by temperature within 1 hour of admission to the NICU in 12 MICs and 22 HICs. RESULTS: Among 201 046 newborns, hypothermia was more common in MIC hospitals (64.0%) compared with HIC hospitals (28.6%). Lower birth weight, small for gestational age status, and prolonged resuscitation were perinatal risk factors for hypothermia. The mortality was doubled for hypothermic compared with euthermic newborns in MICs (24.7% and 15.4%) and HICs (12.7% and 7.6%) hospitals. After adjusting for confounders, the relative risk of death among hypothermic newborns compared with euthermic newborns was 1.21 (95% confidence interval 1.09-1.33) in MICs and 1.26 (95% confidence interval 1.21-1.31) in HICs. Every 1°C increase in admission temperature was associated with a 9% and 10% decrease in mortality risk in MICs and HICs, respectively. CONCLUSIONS: In this large sample of newborns across MICs and HICs, hypothermia remains common and is strongly associated with mortality. The profound burden of hypothermia presents an opportunity for strategies to improve outcomes and achieve the neonatal 2030 Sustainable Development Goal.
