Item Association of Fluid Balance With Short- and Long-term Respiratory Outcomes in Extremely Premature Neonates: A Secondary Analysis of a Randomized Clinical Trial(American Medical Association, 2022-12-01) Starr, Michelle C.; Griffin, Russell; Gist, Katja M.; Segar, Jeffrey L.; Raina, Rupesh; Guillet, Ronnie; Nesargi, Saudamini; Menon, Shina; Anderson, Nekayla; Askenazi, David J.; Selewski, David T.; Pediatrics, School of MedicineImportance: Extremely low gestational age neonates are at risk of disorders of fluid balance (FB), defined as change in fluid weight over a specific period. Few data exist on the association between FB and respiratory outcomes in this population. Objective: To describe FB patterns and evaluate the association of FB with respiratory outcomes in a cohort of extremely low gestational age neonates. Design, setting, and participants: This study is a secondary analysis of the Preterm Erythropoietin Neuroprotection Trial (PENUT), a phase 3 placebo-controlled randomized clinical trial of erythropoietin in extremely premature neonates conducted in 30 neonatal intensive care units in the US from December 1, 2013, to September 31, 2016. This analysis included 874 extremely premature neonates born at 24 to 27 weeks' gestation who were enrolled in the PENUT study. Secondary analysis was performed in November 2021. Exposures: Primary exposure was peak FB during the first 14 postnatal days. The FB was calculated as percent change in weight from birth weight (BW) as a surrogate for FB. Main outcomes and measures: The primary outcome was mechanical ventilation on postnatal day 14. The secondary outcome was a composite of severe bronchopulmonary dysplasia (BPD) or death. Results: A total of 874 neonates (449 [51.4%] male; mean [SD] BW, 801 [188] g; 187 [21.4%] Hispanic, 676 [77.3%] non-Hispanic, and 11 [1.3%] of unknown ethnicity; 226 [25.9%] Black, 569 [65.1%] White, 51 [5.8%] of other race, and 28 [3.2%] of unknown race) were included in this analysis. Of these 874 neonates, 458 (52.4%) received mechanical ventilation on postnatal day 14, and 291 (33.3%) had severe BPD or had died. Median peak positive FB was 11% (IQR, 4%-20%), occurring on postnatal day 13 (IQR, 9-14). A total of 93 (10.6%) never decreased below their BW. Neonates requiring mechanical ventilation at postnatal day 14 had a higher peak FB compared with those who did not require mechanical ventilation (15% above BW vs 8% above BW, P < .001). On postnatal day 3, neonates requiring mechanical ventilation were more likely to have a higher FB (5% below BW vs 8% below BW, P < .001). The median time to return to BW was shorter in neonates who received mechanical ventilation (7 vs 8 days, P < .001) and those with severe BPD (7 vs 8 days, P < .001). After adjusting for confounding variables, for every 10% increase in peak FB during the first 14 postnatal days, there was 103% increased odds of receiving mechanical ventilation at postnatal day 14 (adjusted odds ratio, 2.03; 95% CI, 1.64-2.51). Conclusions and relevance: In this secondary analysis of a randomized clinical trial, peak FB was associated with mechanical ventilation on postnatal day 14 and severe BPD or death. Fluid balance in the first 3 postnatal days and time to return to BW may be potential targets to help guide management and improve respiratory outcomes.Item Documentation of acute kidney injury at discharge from the neonatal intensive care unit and role of nephrology consultation(Springer Nature, 2022) Chmielewski, Jennifer; Chaudhry, Paulomi M.; Harer, Matthew W.; Menon, Shina; South, Andrew M.; Chappell, Ashley; Griffin, Russell; Askenazi, David; Jetton, Jennifer; Starr, Michelle C.; Neonatal Kidney Collaborative; Pediatrics, School of MedicineObjective: To investigate whether NICU discharge summaries documented neonatal AKI and estimate if nephrology consultation mediated this association. Study design: Secondary analysis of AWAKEN multicenter retrospective cohort. Exposures: AKI severity and diagnostic criteria. Outcome: AKI documentation on NICU discharge summaries using multivariable logistic regression to estimate associations and test for causal mediation. Results: Among 605 neonates with AKI, 13% had documented AKI. Those with documented AKI were more likely to have severe AKI (70.5% vs. 51%, p < 0.001) and SCr-only AKI (76.9% vs. 50.1%, p = 0.04). Nephrology consultation mediated 78.0% (95% CL 46.5-109.4%) of the total effect of AKI severity and 82.8% (95% CL 70.3-95.3%) of the total effect of AKI diagnostic criteria on documentation. Conclusion: We report a low prevalence of AKI documentation at NICU discharge. AKI severity and SCr-only AKI increased odds of AKI documentation. Nephrology consultation mediated the associations of AKI severity and diagnostic criteria with documentation.Item Incidence and outcomes of neonatal acute kidney injury (AWAKEN): a multicentre, multinational, observational cohort study(Elsevier, 2017-11) Jetton, Jennifer G.; Boohaker, Louis J.; Sethi, Sidharth K.; Wazir, Sanjay; Rohatgi, Smriti; Soranno, Danielle E.; Chishti, Aftab S.; Woroniecki, Robert; Mammen, Cherry; Swanson, Jonathan R.; Sridhar, Shanty; Wong, Craig S.; Kupferman, Juan C.; Griffin, Russell L.; Askenazi, David J.; Pediatrics, School of MedicineBackground: Single-center studies suggest that neonatal acute kidney injury (AKI) is associated with poor outcomes. However, inferences regarding the association between AKI, mortality, and hospital length of stay are limited due to the small sample size of those studies. In order to determine whether neonatal AKI is independently associated with increased mortality and longer hospital stay, we analyzed the Assessment of Worldwide Acute Kidney Epidemiology in Neonates (AWAKEN) database. Methods: All neonates admitted to 24 participating neonatal intensive care units from four countries (Australia, Canada, India, United States) between January 1 and March 31, 2014, were screened. Of 4273 neonates screened, 2022 (47·3%) met study criteria. Exclusion criteria included: no intravenous fluids ≥48 hours, admission ≥14 days of life, congenital heart disease requiring surgical repair at <7 days of life, lethal chromosomal anomaly, death within 48 hours, inability to determine AKI status or severe congenital kidney abnormalities. AKI was defined using a standardized definition -i.e., serum creatinine rise of ≥0.3 mg/dL (26.5 mcmol/L) or ≥50% from previous lowest value, and/or if urine output was <1 mL/kg/h on postnatal days 2 to 7. Findings: Incidence of AKI was 605/2022 (29·9%). Rates varied by gestational age groups (i.e., ≥22 to <29 weeks =47·9%; ≥29 to <36 weeks =18·3%; and ≥36 weeks =36·7%). Even after adjusting for multiple potential confounding factors, infants with AKI had higher mortality compared to those without AKI [(59/605 (9·7%) vs. 20/1417 (1·4%); p< 0.001; adjusted OR=4·6 (95% CI=2·5-8·3); p=<0·0001], and longer hospital stay [adjusted parameter estimate 8·8 days (95% CI=6·1-11·5); p<0·0001]. Interpretation: Neonatal AKI is a common and independent risk factor for mortality and longer hospital stay. These data suggest that neonates may be impacted by AKI in a manner similar to pediatric and adult patients.Item Reduction of CLABSIs at Riley NICU: It Takes a Village and a Continuous QI Process!(Wolters Kluwer, 2021-08-02) Blazier, Laura A.; Stefanescu, Beatrice M.; Pediatrics, School of MedicineThe NICU population is one of the most vulnerable for central line associated bloodstream infections (CLABSI) due to extended hospitalizations, necessary central line access, and prolonged catheter periods. Unfortunately, CLABSIs are associated with significant morbidity and mortality, as well as increased hospital costs. The objective set was to measure changes in the rate of CLABSI after implementation, ongoing education, and maintenance of our CLABSI bundle with the ultimate goal of achievement and sustainment of “ZERO CLABSI.”
