Purpose: The acquisition and interpretation of clinical results during resuscitations is common; however, this can delay critical clinical tasks, resulting in increased morbidity and mortality. This study aims to determine the impact of clinical result acquisition and interpretation by the team leader on critical task completion during simulated pediatric cardiac arrest before and after team training.

Methods: This is a secondary data analysis of video-recorded simulated resuscitation scenarios conducted during Teams4Kids (T4K) study (June 2011-January 2015); scenarios included cardiac arrest before and after team training.

Rationale, Aims And Objectives: Healthcare practitioners often note system-level barriers to empathy between patients and practitioners. These include burnout-inducing administrative workloads, unfriendly meeting times, burdensome protocols, lack of wellbeing spaces, and undervaluing empathy as a core part of an institution's mission. The need for empathy in healthcare has been magnified with the current SARS-COV-2 outbreak which has limited the expression of interpersonal empathy due to rigid isolation protocols and the use of personal protective equipment.

Article Synopsis
  • The study examines the long-term effects of acute kidney injury (AKI) in children admitted to pediatric intensive care units (PICUs), focusing on kidney abnormalities and blood pressure issues after 6 years.
  • Researchers found that 25% of the 277 children had AKI, with those who experienced stage 2/3 AKI having significantly higher odds of developing chronic kidney disease signs and elevated blood pressure.
  • The findings indicate that kidney and blood pressure problems are prevalent years after PICU admission and are linked to prior AKI, highlighting the need for further research to improve follow-up care and reduce health risks.

Objective: Acute kidney injury occurs early in PICU admission and increases risks for poor outcomes. We evaluated the feasibility of a multicenter acute kidney injury biomarker urine collection protocol and measured diagnostic characteristics of urine neutrophil gelatinase-associated lipocalin, interleukin-18, and liver fatty acid binding protein to predict acute kidney injury and prolonged acute kidney injury.

Design: Prospective observational pilot cohort study.

Simulation-based education often relies on confederates, who provide information or perform clinical tasks during simulation scenarios, to play roles. Although there is experience with confederates in their more routine performance within educational programs, there is little literature on the training of confederates in the context of simulation-based research. The CPR CARES multicenter research study design included 2 confederate roles, in which confederates' behavior was tightly scripted to avoid confounding primary outcome measures.

Background: Physicians often administer corticosteroids for the treatment of fluid and vasoactive infusion dependent pediatric shock. This use of corticosteroids is controversial, however, and has never been studied in a pediatric randomized controlled trial (RCT). This pilot trial will determine the feasibility of a larger RCT on the role of corticosteroids in pediatric shock.

Aim: The variability in quality of CPR provided during cardiac arrest across pediatric institutions is unknown. We aimed to describe the degree of variability in the quality of CPR across 9 pediatric institutions, and determine if variability across sites would be affected by Just-in-Time CPR training and/or visual feedback during simulated cardiac arrest.

Methods: We conducted secondary analyses of data collected from a prospective, multi-center trial.

Background: The prevention of near and actual cardiopulmonary arrest in hospitalized children is a patient safety imperative. Prevention is contingent upon the timely identification, referral and treatment of children who are deteriorating clinically. We designed and validated a documentation-based system of care to permit identification and referral as well as facilitate provision of timely treatment.

Article Synopsis
  • The quality of CPR in pediatric emergencies is crucial for improving survival rates and neurological outcomes, yet many healthcare professionals do not consistently follow established CPR guidelines.
  • A study was conducted to see if "just-in-time" (JIT) training or real-time visual feedback (VisF) could enhance the quality of chest compressions during simulated cardiopulmonary arrest scenarios.
  • Results showed that both JIT training and VisF significantly improved the depth and rate of chest compressions compared to control groups, but neither intervention significantly affected the CPR fraction percentage during the simulations.

Introduction: In adults, small (< 50%) serum creatinine (SCr) increases predict mortality. It is unclear whether different baseline serum creatinine (bSCr) estimation methods affect findings of acute kidney injury (AKI)-outcome associations. We characterized pediatric AKI, evaluated the effect of bSCr estimation approaches on AKI-outcome associations and evaluated the use of small SCr increases to predict AKI development.
