Abstract
BACKGROUND
Acute kidney injury (AKI) is a critical concern in pediatric intensive care units (PICUs) due to its high mortality rate.
OBJECTIVES
Investigate AKI incidence, outcomes, and mortality-related risk factors among critically ill children.
DESIGN
Retrospective cohort.
SETTING
A PICU.
PATIENTS AND METHODS
The study included children (aged 4 weeks to 14 years) who were admitted to the PICU from (2016 to 2019) and developed AKI at King Faisal Specialist Hopsital and Research Centre.
MAIN OUTCOMES MEASURES
AKI incidence, outcomes, and mortality-related risk factors.
SAMPLE SIZE
111 records of patients with AKI.
RESULTS
Of 969 PICU admissions, 111 cases developed AKI and were entered in the analysis, with an incidence rate of (11.5%). The median age was 43 months [interquartile range (IQR): 16-120], with hematology/oncology conditions being the most prevalent underlying diseases (56.8%). Septic shock and nephrotoxin medications were the leading causes of AKI, accounting for (46.8%) and (45.0%), respectively. Regarding AKI severity, (37.8%) were classified as stage 1, (25.2%) as stage 2, and (37.0%) as stage 3 AKI. As for PICU interventions, the highest was inotropic support (63.1%), followed by mechanical ventilation (56.8%) and renal replacement therapy (23.4%). The PICU mortality rate was (38.7%) (43/111), with no significant association between AKI stage and mortality. However, the multivariable analysis identified bone marrow transplant (BMT) (P=.042) and inotropic support (P=.001) as significant predictors of mortality.
CONCLUSION
These findings underscore the importance of early recognition and tailored management of AKI in PICU settings. Despite advancements in critical care, AKI remains a significant challenge, contributing to prolonged hospitalization, mortality, and increased health-care resource utilization. Therefore, more investigation is warranted.
LIMITATIONS
Retrospective study single-center nature.
