Article Synopsis
  • This study focused on understanding how common diagnostic uncertainty is when critically ill children are admitted to Pediatric Intensive Care Units (PICUs) and what factors contribute to it.
  • Researchers reviewed medical records from 882 pediatric patients across four hospitals to assess the presence of diagnostic uncertainty at admission and how it changed by the time of discharge.
  • Key findings indicated that 25.9% of patients showed diagnostic uncertainty upon PICU admission, with significant factors being the time of admission, illness severity, atypical symptoms, and discrepancies in diagnoses between different healthcare providers.

Background: Acute kidney injury (AKI) is independently associated with increased morbidity and mortality across the life course, yet care for AKI remains mostly supportive. Raising awareness of this life-threatening clinical syndrome through education and advocacy efforts is the key to improving patient outcomes. Here, we describe the unique roles education and advocacy play in the care of children with AKI, discuss the importance of customizing educational outreach efforts to individual groups and contexts, and highlight the opportunities created through innovations and partnerships to optimize lifelong health outcomes.

The nephrology and critical care communities have seen an increase in studies exploring acute kidney injury (AKI) epidemiology in children. As a result, we now know that AKI is highly prevalent in critically ill neonates, children, and young adults. Furthermore, children who develop AKI experience greater morbidity and higher mortality.

Over the past two decades, our understanding of the impact of acute kidney injury, disorders of fluid balance, and their interplay have increased significantly. In recent years, the epidemiology and impact of fluid balance, including the pathologic state of fluid overload on outcomes has been studied extensively across multiple pediatric and neonatal populations. A detailed understating of fluid balance has become increasingly important as it is recognized as a target for intervention to continue to work to improve outcomes in these populations.

Objectives: Effective interventions to prevent diagnostic error among critically ill children should be informed by diagnostic error prevalence and etiologies. We aimed to determine the prevalence and characteristics of diagnostic errors and identify factors associated with error in patients admitted to the PICU.

Design: Multicenter retrospective cohort study using structured medical record review by trained clinicians using the Revised Safer Dx instrument to identify diagnostic error (defined as missed opportunities in diagnosis).

Article Synopsis
  • The aim of the study was to see if hospitals that have ECMO (a special machine that helps kids who have serious heart or breathing problems) help more children survive cardiac arrest compared to hospitals without it.
  • Researchers looked at data from kids who had cardiac arrests in hospitals between 2016 and 2018, focusing on how many survived after treatment.
  • They found that kids treated at hospitals with ECMO had a better chance of surviving (50%) compared to those at hospitals without it (32%), suggesting that having ECMO can lead to better outcomes for kids in cardiac arrest.

Objectives: With the recognition that fluid overload (FO) has a detrimental impact on critically ill children, the critical care nephrology community has focused on identifying clinically meaningful targets for intervention. The current study aims to evaluate the epidemiology and outcomes associated with FO in an international multicenter cohort of critically ill children. The current study also aims to evaluate the association of FO at predetermined clinically relevant thresholds and time points (FO ≥ 5% and FO ≥ 10% at the end of ICU days 1 and 2) with outcomes.

Prior criteria for organ dysfunction in critically ill children were based mainly on expert opinion. We convened the Pediatric Organ Dysfunction Information Update Mandate (PODIUM) expert panel to summarize data characterizing single and multiple organ dysfunction and to derive contemporary criteria for pediatric organ dysfunction. The panel was composed of 88 members representing 47 institutions and 7 countries.

Article Synopsis
  • Acute kidney injury (AKI) and fluid overload (FO) are significant issues in children undergoing extracorporeal membrane oxygenation (ECMO), particularly in cases of extracorporeal cardiopulmonary resuscitation (eCPR).
  • A study involving 131 patients found that those with fluid overload at ECMO discontinuation had a higher risk of mortality and a longer hospital stay regardless of AKI status.
  • The findings highlight the need for future research to focus on effective fluid management strategies in children receiving eCPR.

Fluid overload (FO) and acute kidney injury (AKI) occur commonly in children supported with extracorporeal membrane oxygenation (ECMO). Continuous renal replacement therapy (CRRT) may be used to manage AKI and FO in children on ECMO. In 2012, our group surveyed ECMO centers to begin to understand the practice patterns around CRRT and ECMO.

Background: The consensus definition of acute kidney injury (AKI) has evolved since developing the original multiple organ dysfunction syndrome (MODS) definitions. Whether or not risk for adverse short- and long-term outcomes can be identified using the refined AKI criteria in the setting of MODS has not been studied. We hypothesize that incorporation of Kidney Disease: Improving Global Outcome (KDIGO) AKI criteria into existing MODS definitions will have a higher association with major adverse kidney events at 30 days (MAKE30) and will increase the number of patients with MODS.

Article Synopsis
  • The study aimed to evaluate the use of continuous renal replacement therapy (CRRT) alongside extracorporeal membrane oxygenation (ECMO) in children and its impact on mortality related to fluid overload.
  • A total of 756 out of 1009 children on ECMO had complete data, with a survival rate to ECMO decannulation of 66.4% and to hospital discharge of 44.3%.
  • The findings indicated that lower fluid overload at both the start and end of CRRT was linked with higher survival rates, and fluid overload levels were significant predictors of mortality in hospitalized patients.
