Standardizing the Evaluation and Management of Necrotizing Enterocolitis in a Level IV NICU.

OBJECTIVES: Necrotizing enterocolitis (NEC) is a severe intestinal inflammatory disease and a leading cause of morbidity and mortality in NICUs. Management of NEC is variable because of the lack of evidence-based recommendations. It is widely accepted that standardization of patient care leads to improved outcomes. This quality improvement project aimed to decrease variation in the evaluation and management of NEC in a Level IV NICU. METHODS: A multidisciplinary team investigated institutional variation in NEC management and developed a standardized guideline and electronic medical record tools to assist in evaluation and management. Retrospective baseline data were collected for 2 years previously and prospectively for 3.5 years after interventions. Outcomes included the ratio of observed-to-expected days of antibiotics and nil per os (NPO) on the basis of the novel guidelines and the percentage of cases treated with piperacillin/tazobactam. Balancing measures were death, surgery, and antifungal use. RESULTS: Over 5.5 years, there were 124 evaluations for NEC. Special cause variation was noted in the observed-to-expected antibiotic and NPO days ratios, decreasing from 1.94 to 1.18 and 1.69 to 1.14, respectively. Piperacillin/tazobactam utilization increased from 30% to 91%. There were no increases in antifungal use, surgery, or death. CONCLUSIONS: Variation in evaluation and management of NEC decreased after initiation of a guideline and supporting electronic medical record tools, with fewer antibiotic and NPO days without an increase in morbidity or mortality. A quality improvement approach can benefit patients and decrease variability, even in diseases with limited evidence-based standards.

Effect of a Low-Dose/High-Frequency Training in Introducing a Nurse-Led Neonatal Advanced Life Support Service in a Referral Hospital in Ethiopia.

Background and Objective: In Ethiopia, birth asphyxia causes ~30% of all neonatal deaths and 11-31% of deaths among neonates delivered in healthcare facilities that have breathing difficulty at birth. This study aimed to examine the impact of low-dose, high-frequency (LDHF) training for introducing a nurse-led neonatal advanced life support (NALS) service in a tertiary care hospital in Ethiopia. Methods: Through a retrospective cohort study, a total of 12,001 neonates born post-implementation of the NALS service (between June 2017 and March 2019) were compared to 2,066 neonates born before its implementation (between June 2016 and September 2016). Based on when the neonates were born, they were divided into six groups (groups A to F). All deliveries occurred in the inpatient Labor and Delivery Unit (LDU) at St. Paul's Hospital Millennium Medical College. The number of neonatal deaths in the LDU, neonatal intensive care unit (NICU) admission rate, and proportion of neonates with normal axillary temperature (36.5-37.5°C) within the first hour of life were evaluated. Data were analyzed using the χ2 test, and p-values < 0.05 were considered statistically significant. Following the implementation of the NALS service, semi-structured interviews with key stakeholders were conducted to evaluate their perception of the service; the interviews were recorded, transcribed, and coded for thematic analysis. Results: There was a decrease in the proportion of neonates who died in the LDU (from 3.5 to 1%) during the immediate post-implementation period, followed by a sustained decrease over the study period (p < 0.001). The change in the NICU admission rate (from 22.8 to 21.2%) was insignificant (p = 0.6) during this initial period. However, this was followed by a significant sustained decrease (7.8% in group E and 9.8% in group F, p < 0.001). The proportion of newborns with normal axillary temperature improved from 46.2% during the initial post-implementation period to 87.8% (p < 0.01); this proportion further increased to 99.8%. The program was perceived positively by NALS team members, NICU care providers, and hospital administrators. Conclusion: In resource-limited settings, LDHF training for neonatal resuscitation improves the neonatal resuscitation skills and management of delivery room attendants.

Relationship Between Moral Distress and Intent to Leave a Position Among Neonatal Intensive Care Nurses.

BACKGROUND: The phenomenon of moral distress is prevalent in the literature, but little is known about the experiences of nurses working in the neonatal intensive care unit (NICU). In addition, a paucity of literature exists exploring the relationship between moral distress and intent to leave a position in NICU nurses. PURPOSE: To explore the phenomenon of moral distress in NICU nurses using the Measure of Moral Distress for Health Care Professionals (MMD-HP) survey. METHODS: A cross-sectional, descriptive, correlational study was conducted nationally via an electronic survey distributed to NICU nurses who are members of National Association of Neonatal Nurses (NANN). Participants were asked to electronically complete the MMD-HP survey between March 27 and April 8, 2020. FINDINGS: A total of 75 NICU nurses completed the survey, and 65 surveys were included for data analysis. Five situations from the survey had a composite MMD-HP score of more than 400. Results indicated that 41.5% of the NICU nurses surveyed considered leaving a clinical position due to moral distress, and 23.1% of the nurses surveyed left a position due to moral distress. IMPLICATIONS: for Practice: NICU nurses experiencing high MMD-HP scores are more likely to leave a position. Further research is needed to develop strategies useful in mitigating moral distress in and prevent attrition of NICU nurses. IMPLICATIONS FOR RESEARCH: Many NICU nurses experiencing high levels of moral distress have left positions or are considering leaving a clinical position. Longitudinal interventional studies are vital to understand, prevent, and address the root causes of moral distress experienced by NICU nurses.

Rho/SMAD/mTOR triple inhibition enables long-term expansion of human neonatal tracheal aspirate-derived airway basal cell-like cells.

BACKGROUND: Bronchopulmonary dysplasia remains one of the most common complications of prematurity, despite significant improvements in perinatal care. Functional modeling of human lung development and disease, like BPD, is limited by our ability to access the lung and to maintain relevant progenitor cell populations in culture. METHODS: We supplemented Rho/SMAD signaling inhibition with mTOR inhibition to generate epithelial basal cell-like cell lines from tracheal aspirates of neonates. RESULTS: Single-cell RNA-sequencing confirmed the presence of epithelial cells in tracheal aspirates obtained from intubated neonates. Using Rho/SMAD/mTOR triple signaling inhibition, neonatal tracheal aspirate-derived (nTAD) basal cell-like cells can be expanded long term and retain the ability to differentiate into pseudostratified airway epithelium. CONCLUSIONS: Our data demonstrate that neonatal tracheal aspirate-derived epithelial cells can provide a novel ex vivo human cellular model to study neonatal lung development and disease. IMPACT: Airway epithelial basal cell-like cell lines were derived from human neonatal tracheal aspirates. mTOR inhibition significantly extends in vitro proliferation of neonatal tracheal aspirate-derived basal cell-like cells (nTAD BCCs). nTAD BCCs can be differentiated into functional airway epithelium. nTAD BCCs provide a novel model to investigate perinatal lung development and diseases.
