Critical Event Checklists for Simulated In-Hospital Dysrhythmias in Children with Heart Disease

Children with heart disease are at increased risk of unstable dysrhythmias and in-hospital cardiac arrest (IHCA). Clinician adherence to lifesaving processes of care is an important contributor to improving patient outcomes. This study evaluated whether critical event checklists improve adherence to lifesaving processes during simulated acute events secondary to unstable dysrhythmias. A randomized controlled trial was conducted in a cardiac ward in a tertiary care, academic children's hospital. Unannounced simulated emergencies involving dysrhythmias in pediatric patients with underlying cardiac disease were conducted weekly. Responders were pediatric and anesthesiology residents, respiratory therapists, and bedside registered nurses. Six teams were randomized into two groups-three received checklists (intervention) and three did not (control). Each team participated in four simulated scenarios over a 4-week pediatric cardiology rotation. Participants received a brief slideshow presentation, which included a checklist orientation, at the start of their rotation. Simulations were video and audio recorded and those with three or more participants were included for analysis. The primary outcome was team adherence to lifesaving processes, expressed as the percentage of completed critical management steps. Secondary outcomes included participant perceptions of the checklist usefulness in identifying and managing dysrhythmias. We used generalized estimating equations (GEE) models, which accounted for clustering within groups, to evaluate the effects of the intervention. A total of 24 simulations were conducted; one of the 24 simulations was excluded due to an insufficient number of participants. In our GEE analysis, 81.21% (78.96%, 83.47%) of critical steps were completed with checklists available versus 68.06% (59.38%, 76.74%) without checklists (p = 0.004). Ninety-three percent of study participants reported that they would use the checklists during an unstable dysrhythmia of a child with underlying cardiac disease. Checklists were associated with improved adherence to lifesaving processes during simulated resuscitations for unstable pediatric dysrhythmias. These findings support the use of scenario specific checklists for the management of unstable dysrhythmias in simulations involving pediatric patients with underlying cardiac disease. Future studies should investigate whether checklists are as effective in actual pediatric in-hospital emergencies.
