Documentation of acute kidney injury at discharge from the neonatal intensive care unit and role of nephrology consultation

Academic Article


  • Objective: 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.
