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

BACKGROUND: Early Neonatal mortality (ENM) (< 7 days) remains a significant problem in low resource settings. Birth asphyxia (BA), prematurity and presumed infection contribute significantly to ENM. The study objectives were to determine: first, the overall ENM rate as well as yearly ENM rate (ENMR) from 2015 to 2019; second, the influence of decreasing GA (< 37 weeks) and BW (< 2500 g) on ENM; third, the contribution of intrapartum and delivery room factors and in particular fetal heart rate abnormalities (FHRT) to ENM; and fourth, the Fresh Still Birth Rates (FSB) rates over the same time period. METHODS: Retrospective cohort study undertaken in a zonal referral teaching hospital located in Northern Tanzania. Labor and delivery room data were obtained from 2015 to 2019 and included BW, GA, fetal heart rate (FHRT) abnormalities, bag mask ventilation (BMV) during resuscitation, initial temperature, and antenatal steroids use. Abnormal outcome was ENM < 7 days. Analysis included t tests, odds ratios (OR), and multivariate regression analysis. RESULTS: The overall early neonatal mortality rate (ENMR) was 18/1000 livebirths over the 5 years and did not change significantly comparing 2015 to 2019. Comparing year 2018 to 2019, the overall ENMR decreased significantly (OR 0.62; 95% confidence interval (CI) 0.45-0.85) as well as infants ≥37 weeks (OR 0.45) (CI 0.23-0.87) and infants < 37 weeks (OR 0.57) (CI 0.39-0.84). ENMR was significantly higher for newborns < 37 versus ≥37 weeks, OR 10.5 (p < 0.0001) and BW < 2500 versus ≥2500 g OR 9.9. For infants < 1000 g / < 28 weeks, the ENMR was ~ 588/1000 livebirths. Variables associated with ENM included BW - odds of death decreased by 0.55 for every 500 g increase in weight, by 0.89 for every week increase in GA, ENMR increased 6.8-fold with BMV, 2.6-fold with abnormal FHRT, 2.2-fold with no antenatal steroids (ANS), 2.6-fold with moderate hypothermia (all < 0.0001). The overall FSB rate was 14.7/1000 births and decreased significantly in 2019 when compared to 2015 i.e., 11.3 versus 17.3/1000 live births respectively (p = 0.02). CONCLUSION: ENM rates were predominantly modulated by decreasing BW and GA, with smaller/ less mature newborns 10-fold more likely to die. ENM in term newborns was strongly associated with FHRT abnormalities and when coupled with respiratory depression and BMV suggests BA. In smaller newborns, lack of ACS exposure and moderate hypothermia were additional associated factors. A composite perinatal approach is essential to achieve a sustained reduction in ENMR.

Implementation of a novel bubble continuous positive airway pressure system with a blender in preterm infants in a low resource setting.

OBJECTIVE: To determine if a novel CPAP system is associated with physiologic improvement in premature infants in a low resource setting and if the introduction of blended oxygen would reduce FiO2. STUDY DESIGN: Feasibility study of infants ≤2000 g or ≤32 weeks gestational age with early respiratory distress who were placed on Vayu CPAP with continuous pulse oximetry. Physiologic parameters were recorded prior to initiation and through the first 24 h. RESULTS: Seventy-six infants of birthweight 1360 ± 324 g and gestational age 31.2 ± 2.5 weeks were included. Compared to baseline, heart rate, respiratory rate, FiO2, and Silverman Anderson score significantly decreased while oxygen saturations significantly increased at one hour with persistence through 24 h. CONCLUSION: Utilization of Vayu CPAP in premature infants with respiratory distress was associated with immediate improvement in physiologic parameters. Use of blended oxygen coupled with pulse oximetry facilitates reduction in delivered oxygen.

Reducing NICU Unplanned Extubations From Tube Dislodgement.

OBJECTIVES: Unplanned extubations (UEs) can be a frequent problem and are associated with adverse outcomes. This quality improvement initiative sought to reduce UEs from tube dislodgement in a level IV NICU utilizing methods applicable to other ICUs and performed with minimal monetary funds. METHODS: From January 2019 to July 2023, an interdisciplinary quality improvement team used the Model for Improvement and performed sequential interventions to improve the outcome measure of UEs per 100 ventilator days. Process measures included adherence to a modified, site-specific UE care bundle derived from the Solutions for Patient Safety network, whereas the number of endotracheal tube-related pressure injuries was used as a balancing measure. Statistical process control charts and established rules for special cause variation were applied to analyze data. RESULTS: Sequential interventions reduced the rate of UEs from a baseline of 2.3 to 0.6 UEs per 100 ventilator days. Greater than 90% adherence with the UE care bundle and apparent cause analysis form completion occurred since December 2020. There were no endotracheal tube-related pressure injuries. CONCLUSIONS: A sustained reduction in UEs was demonstrated. Leveraging a multidisciplinary team allowed for continuous UE analysis, which promoted tailored consecutive interventions. UE care bundle audits and the creation of a postevent debrief guide, which helped providers share a common language, were the most impactful interventions. Next steps include disseminating these interventions to other ICUs across our hospital enterprise. These low-cost interventions can be scalable to other NICUs and PICUs.

Capacity Building in Remote Facilitation of Newborn Resuscitation.

The past decade has been notable for widespread dissemination of newborn resuscitation training in low-resource settings through simplified training programs including Helping Babies Breathe. Since 2020, implementation efforts have been impacted by restrictions on travel and in-person gatherings with the SARS-CoV-2 pandemic, prompting the development of alternative methods of training. While previous studies have demonstrated feasibility of remote neonatal resuscitation training, this perspective paper covers common barriers identified and key lessons learned developing a cadre of remote facilitators. Challenges of remote facilitation include mastering videoconferencing platforms, establishing personal connections, and providing effective oversight of skills practice. Training sessions can be used to support facilitators in acquiring comfort and competency in harnessing videoconferencing platforms for effective facilitation. Optimization of approaches and investment in capacity building of remote facilitators are imperative for effective implementation of remote neonatal resuscitation training.
