ObjectiveTo characterise the excess risk for death, grade 3–4 intraventricular haemorrhage (IVH), bronchopulmonary dysplasia (BPD) and stage 3–5 retinopathy of prematurity independently associated with birth small for gestational age (SGA) among very preterm infants, stratified by completed weeks of gestation.MethodsRetrospective cohort study using the Optum Neonatal Database. Study infants were born <32 weeks gestation without severe congenital anomalies. SGA was defined as a birth weight <10th percentile. The excess outcome risk independently associated with SGA birth among SGA babies was assessed using adjusted risk differences (aRDs).ResultsOf 6708 infants sampled from 717 US hospitals, 743 (11.1%) were SGA. SGA compared with non-SGA infants experienced higher unadjusted rates of each study outcome except grade 3–4 IVH among survivors. The excess risk independently associated with SGA birth varied by outcome and gestational age. The highest aRD for death (0.27; 95% CI 0.13 to 0.40) occurred among infants born at 24 weeks gestation and declined as gestational age increased. In contrast, the peak aRDs for BPD among survivors (0.32; 95% CI 0.20 to 0.44) and the composites of death or BPD (0.35; 95% CI 0.24 to 0.46) and death or major morbidity (0.35; 95% CI 0.24 to 0.45) occurred at 27 weeks gestation. The risk-adjusted probability of dying or developing one or more of the evaluated morbidities among SGA infants was similar to that of non-SGA infants born approximately 2–3 weeks less mature.ConclusionThe excess risk for neonatal morbidity and mortality associated with being born SGA varies by adverse outcome and gestational age.

Abstract Primary Subject area Neonatal-Perinatal Medicine Background In a health care system with limited resources, hospital organizational factors such as unit occupancy and nurse-to-patient ratios may contribute to patient outcomes. Objectives We aimed to assess the association of NICU occupancy and nurse staffing with outcomes of very preterm infants born &lt; 33 weeks gestational age (GA). Design/Methods This was a multicenter retrospective cohort study of infants born 23-32 weeks GA without major congenital anomaly, admitted within 2 days after birth to one of four Level 3 NICUs in Quebec, Canada (2015-2018). For each 8 h shift, data on unit occupancy were obtained from a central provincial database (SiteNeo) and linked to the hospital nursing hours database (Logibec). Unit occupancy rates and nursing provision ratios (nursing hours/recommended nursing hours based on patient dependency categories) were pooled for the first shift, 24 h, and 7 days of admission for each infant. Patient data were obtained from the Canadian Neonatal Network database. Primary outcome was mortality and/or morbidity (severe neurological injury, bronchopulmonary dysplasia, necrotizing enterocolitis, and late-onset sepsis, severe retinopathy of prematurity). Adjusted odds ratios (AOR) for association of exposure with outcomes were estimated using generalized linear mixed models with a random effect for center, while adjusting for confounders (gestational age, small for gestational age, sex, outborn, Score for Neonatal Acute Physiology version 2, mode of delivery, and the other organizational variables). Results Among 1870 infants included in analyses, 796 (43%) had mortality/morbidity. Median occupancy was 89% (IQR 82-94) and median nursing provision was 1.13 (IQR 0.97-1.37). Overall higher NICU occupancy on shift of admission, first 24 h, and 7 days were associated with higher odds of mortality/morbidity (Figure 1) but nursing provision was not (Figure 2). Subgroup analysis by GA (&lt; 29 and 29-32 weeks) yielded similar results (not shown). Generalized linear mixed model analyses showed that a 5% reduction in occupancy in the first 24 h of admission was associated with a 6% reduction in mortality/morbidity. Conclusion NICU occupancy is associated with mortality/morbidity among very preterm infants and may reflect lack of adequate resources in periods of high activity. Interventions aimed at reducing occupancy and maintaining adequate resources need to be considered as strategies to improve patient outcomes.

Background: Oxygen supplementation is an important component for preterm infants neonatal care. Pulse oximetry (SpO2) is essential to guide oxygen therapy. Evidence on SpO2 values in premature infants previous to discharge is limited. Objectives: To establish SpO2 values in asymptomatic premature infants at 34, 35, and 36 weeks postmenstrual age (PMA). Methods: Longitudinal, multicentric study. From May 2018 to May 2019 premature infants born ≤32 weeks gestational age, from three level III NICUs in Santiago, Chile (altitude 579mt), were enrolled. Healthy children without current apnea of prematurity were included. Continuous SpO2 was obtained with Masimo-Radical 7/8 (USA), averaging time 2-4 seconds. Results: 101 SpO2 recordings (n = 44, 33 and 24 at 34, 35 and 36 weeks PMA respectively) from 62 infants. Twenty eight (45%) male, median (range) gestational age at birth 30 (26-32) weeks, median (range) birth weight 1480 (785-2700) g. Oximetry variables for total recordings: mean SpO2, median (range) 96.9 (93.3-99.3); minimum SpO2, median (range) 74 (51-89); time of SpO2 <90%, median (range) 2% (0-10.6%); time of SpO2 <80%, median (range) 0.1% (0-1.3%); desaturation event by ≥4% (DI4) ≥ 0 and ≥ 10 seconds per sample hour, median (range) 45.2 (5.2-115) and median (range) 15 (3.5-62.5) respectively; desaturation event <80% (DI80), median (range) 0.58 (0-10.8). We found no differences between SpO2 values at different weeks PMA. Conclusions: We described SpO2 values in very preterm infants, asymptomatic at 34, 35 and 36 weeks PMA. These values could be used as a reference to guide oxygen therapy previous to discharge.
