Background: Despite medical advancements, preterm birth rates in the United States remain high and contribute substantially to infant mortality and long-term morbidity, with Black families disproportionately affected. Very preterm (VPT) infants—born between 24 and 30 weeks’ gestation—are frequently delivered at community hospitals that lack advanced neonatal care and therefore require postnatal transport to tertiary neonatal intensive care units (NICUs). While neonatal transport is essential for optimizing infant outcomes, it can create additional challenges for families, including geographic separation from the NICU, disruptions to early parent-infant bonding, and increased parental psychosocial stress. These challenges may be further intensified by social vulnerability and experiences of perceived discrimination in health care settings. Objective: This study examines associations between neonatal transport, infant health outcomes, and the psychosocial well-being of Black parents with VPT infants. It also examines how structural inequities and social vulnerability shape experiences from delivery through NICU hospitalization. Methods: This protocol describes a longitudinal mixed methods multiple case study at a single perinatal center in South Carolina. Up to 10 cases of VPT Black infants transported from community hospitals between May 2023 and January 2024 are included. Each case includes the infant and mother, with partners invited. Quantitative data include infant outcomes from electronic medical records, neighborhood disadvantage using the Area Deprivation Index, and parent surveys of stress, anxiety, depression, bonding, perceived discrimination, and access to care. Qualitative data come from semistructured interviews guided by an adaptation of the National Institute on Minority Health and Health Disparities Research Framework and analyzed using reflexive thematic analysis. Data are integrated within each case to create structured summaries, followed by cross-case comparisons to identify patterns and variation. Results: The study was funded by the National Institute of Nursing Research in July 2023. Participant enrollment occurred between May 2023 and January 2024, with 6 cases enrolled. Data collection and electronic medical record abstraction were completed in May 2024, with analysis completed by July 2024. This manuscript reports the protocol and analytic plan. Detailed results will be reported in 2 companion manuscripts currently under review; publication of one is anticipated in fall 2026. Conclusions: This protocol outlines a novel mixed methods case study of neonatal transport and infant and parent outcomes among Black families. The study is exploratory and intended to generate hypotheses and inform future larger scale research and intervention development to support parental mental health, reduce disparities, and improve care experiences following preterm birth and neonatal transport.

Background: The birthrate of Black preterm (BPT) infants is 65% higher than White preterm (WPT) infants with a BPT mortality that is 2.3 times higher. The incidence of culture-positive late-onset sepsis is as high as 41% in very-preterm infants. The main purpose of this study was to examine thermal gradients and the heart rate in relation to the onset of infection. This report presents disparities in very-preterm infection incidence, bacteria, and mortality data amongst BPT and WPT infants. Methods: 367 preterms born at p = 0.2313) and 27.67 (SD 2.00, p = 0.982) weeks GA. Of the 426 episodes of suspected infections evaluated across all the enrolled infants, the incidence of early-onset sepsis (EOS) was 1.9%, with BPT infants having 2.50 times higher odds of EOS than WPT infants (p = 0.4130, OR (odds ratio) = 2.50, p_or = 0.408). The overall incidence of late-onset sepsis (LOS) was 10.8%, with LOS in 11.9% of BPT infants versus 9.3% (p = 0.489, OR = 1.21, p_or = 0.637) of WPT infants. BPT infants made up 69.2% of the 39 infants with Gram-positive infections vs. 25.6% for WPT infants; 16 infants had Gram-negative culture-positive infections, with 81.2% being BPT infants versus 18.8% being WPT infants. Of the 27 urinary tract infections, 78% were in BPTs. The necrotizing enterocolitis incidence was 6.9%; the incidence in BPT infants was 7.5% vs. 6.5% in WPT infants. The overall mortality was 8.3%, with BPTs at 8.4% vs. WPT infants at 9.3%, (p = 0.6715). Conclusions: BPTs had a higher rate of positive cultures, double the Gram-negative infections, a much higher rate of urinary tract infections, and a higher rate of mortality than their WPT counterparts. This study emphasizes the higher risk of morbidity and mortality for BPTs.

Background: The birthrate of Black preterm (BPT) infant is 65% higher than White preterm (WPT) infants with BPT mortality 2.3 times higher. The incidence of culture positive sepsis is as high as 41% in preterms. This study aimed to examine infections and mortality in BPTs and WPTs. Methods: We enrolled 362 preterms born < 32 weeks gestational age (GA) between 2019-2023 in 5 neonatal intensive care unit (NICU)s to study onset of infections, and dispositions; RedCap data were analyzed for descriptive statistics. Results: 226 BPTs (63.5%) and 107 WPTs (30.8%) enrolled, with 29 other than White or Black, 50.5% female, mean GA of 27.67 weeks and 986.74 grams birthweight. Of 426 suspected infections evaluated in enrolled infants, there were 7 infants with early onset sepsis (EOS) and 39 infants with late onset sepsis (LOS). The incidence of EOS was 1.9% overall, 2.2% in BPTs vs 0.9% in WPTs. LOS incidence was 10.8% overall, 11.9% in BPTs and 9.3% in WPTs. Both BPT and WPT infants had ~ 8% gram-positive LOS events and 3% gram-negative LOS events; however, 82% of all gram-negative LOS episodes occurred in BPTs. There were 27 urinary tract infections and 78% were in BPTs. Two cerebral spinal fluid cultures were positive in BPTs. Necrotizing enterocolitis was diagnosed in 5.8% of the sample, with an incidence of 6.1% in BPTs versus 4.7% in WPTs. Death occurred in 6.0% of the enrolled infants with the rate of death being slightly higher in BPTs (7.0%) versus WPTs (5.6%). Conclusions: BPTs had a higher rate of positive cultures, double the gram-negative infections, a much higher rate of urinary tract infec-tions and a higher rate of mortality than their WPT counterparts. This study emphasizes higher risk of morbidity and mortality for BPTs.

Neonatal hypothermia poses an increased risk of infection, hypoglycemia, metabolic dysfunction, and mortality, particularly in preterm or low birthweight (LBW) infants. However, early detection of hypothermia and prompt thermoregulation can mitigate these effects thus, the need for continuous neonatal temperature monitoring. The BEMPU TempWatch is a small bracelet designed for continuous temperature monitoring for neonates. When the body temperature falls below 36.5˚C, the bracelet generates an alarm sound and flashes an orange light, indicating hypothermia. This study aimed to assess the validity of the BEMPU TempWatch in detecting hypothermia in a clinical setting in Ghana using sensitivity and specificity. Additionally, the study sought to identify factors associated with misclassification using logistic regression analysis. A standardized questionnaire collected information about the mother, pregnancy, delivery, and neonate. The BEMPU TempWatch was placed on the wrist of the neonate, and over a 24-hour follow-up period, a nurse took 4-hourly axillary temperature readings using a digital thermometer. Whenever the device’s alarm sounded, a nurse immediately checked and recorded the axillary temperature, undertook necessary clinical actions, and rechecked after 30 minutes. Among the 249 neonates included in the study, 57.0% were female, 12.5% were extremely LBW, and 13.7% were extremely preterm. Based on 1,973 temperature readings, the sensitivity of the BEMPU TempWatch in detecting hypothermia was 67.8%, and the specificity was 95.9%. The sensitivity was lower among neonates being treated in incubators (58.4%) compared to those not (82.7%). Sensitivity was higher among neonates with LBW (1,500–2,500g) (73.5%) than very or extremely LBW neonates (<1,500g) (62.8%). The results showed that the BEMPU TempWatch had significantly fewer misclassifications among neonates who were not treated in an incubator, received only breastmilk, and were not born extremely preterm. Further studies are warranted to evaluate the effectiveness of the BEMPU TempWatch on neonatal health outcomes.

Background: Very preterm infants (less than 32 weeks gestational age) experience acute morbidity during their stay in a neonatal intensive care unit. Because of their prematurity and frequent laboratory testing, they experience anemia, requiring correction with packed red blood cell (PRBC) transfusion(s). PRBC transfusions have been linked to neonatal morbidity, such as necrotizing enterocolitis, but never signs and symptoms of physiological stability. Objective: The secondary data analysis aimed to examine very preterm infants’ physiological stability before, during, and after PRBC transfusions. Methods: A within-case, mixed-methods design was used in a secondary data analysis for 16 transfusion cases from 13 very preterm infants. Results: The findings showed very preterm infants with physiological variables falling within defined limits based on gestational age during the transfusion. Two contrasting case exemplars will be presented. Discussion: PRBC transfusions are necessary and prevent morbidity in very preterm infants. Observing instability during transfusions and prospectively studying hypothermia, cardiac instability, and thermal gradients is essential to design interventions to decrease morbidity associated with PRBC transfusions.

Background: The coronavirus pandemic disrupted normal clinical operations and research. Nurse scientists conducting research studies in the neonatal intensive care unit experienced significant challenges to continuing their research studies amid national lockdowns and hospital visitation restrictions. Objectives: The purpose of this article is to describe the challenges encountered by nurse scientists conducting research studies in the neonatal intensive care unit during the pandemic, the creative solutions devised to overcome these barriers, and the lessons learned during this unprecedented time. Methods: Using our pandemic area studies as exemplars, we highlight the barriers encountered in continuing our research in the intense environment of the neonatal intensive care unit. Results: Visitor restrictions limited the presence of parents and researchers in the neonatal intensive care unit during the pandemic, causing disruptions to participant recruitment and data collection. Laboratory closures further limited research activities during the pandemic. Strategies to overcome these barriers include building formal collaborations among researchers and clinicians, creating the infrastructure to support virtual recruitment and electronic consent, and developing contingency plans for studies involving the analysis of biological samples. Discussion: The neonatal intensive care unit is a unique environment because of vulnerable patient population and need for researchers to interact with parents to recruit study participants. Implementing the strategies developed during the coronavirus pandemic may allow for the continuation of research activities during future public health crises.

Background: Previously, we recorded periods of time with foot higher than abdominal temperatures in association with infection in preterm infants. Monitoring dual temperatures may be an important tool to assess infant instability. Currently, incubators cannot measure and display dual temperatures in servo-control mode. Purpose: To examine the usability of GE Healthcare's Giraffe OmniBed with research software to measure, display, and record dual temperatures, and their differences while in servo-control. In addition, nurses' perceptions of the use and display of dual temperatures and differences were evaluated. Methods: A multiple-case, mixed-methods design. Abdominal and foot temperatures were measured, displayed, and stored for 28 days for 14 preterm infants. Nurses were surveyed for satisfaction and preferences with the dual temperature display. Nurses noted abnormal temperature differences and infant condition in bedside journals. Results: Study infants were 26 to 31 weeks of gestational age and 670 to 1410 g. Abdominal, foot, and the abdominal-foot temperature difference was measured, recorded, and downloaded successfully in all infants over all days. Nurses liked using dual temperature display with the abdominal-foot temperature difference. Surveys indicated preferences for larger displays and alarms for abnormal values. Thermal instability, stimulation, and thermistor detachment were associated with abnormal thermal gradients. Two exemplar cases are presented. Implications for Practice: Monitoring dual temperatures adds information to the clinical assessment. Implications for Research: Studies are needed to examine relationships between abnormal thermal gradients and infections, infant stability, and nursing care along with the underlying physiologic mechanisms. Studies are needed for wireless dual temperature monitoring.
