Background: Pediatric cardiac arrest (PCA) is a rare event but associated with high morbidity and mortality. Despite advancements in high-fidelity simulation and PALS/EPALS training, critical issues remain regarding the optimal management of pediatric emergencies. In this context, audiovisual cognitive aids have shown potential in improving resuscitation performance and reducing errors during resuscitation. However, their role within educational settings is not yet clearly defined. Study Objective: The primary aim of this study was to evaluate the educational effectiveness of an innovative audiovisual cognitive aid (the PediAppRREST app) compared to the traditional paper-based cognitive aid (PALS Pocket card) during the simulated management of a PCA scenario. The primary outcome was to determine whether the use of PediAppRREST leads to improved clinical performance in the second of two simulated scenarios, which was conducted without any cognitive aids (assessment carried out using the validated Clinical Performance Tool, CPT). Secondary outcomes included: 1. Evaluation of the quality and timing of resuscitative interventions in accordance with PALS guidelines; 2. Analysis of the perceived workload of the team leader (NASA-TLX scale); 3. Measurement of CPR quality (CPR Quality, Laerdal system); 4. Subjective self-assessment of knowledge consolidation (via a questionnaire developed by the research team). Materials and Methods: A randomized pilot study with two parallel arms was conducted, involving 100 medical residents from the University of Padua. Participants were divided into 26 teams of four members, each led by a certified PALS team leader, and were randomly assigned to two groups: the Intervention group (using PediAppRREST) and the Control group (using the PALS Pocket card). Each team managed two consecutive simulated PCA scenarios, each lasting 8 minutes: the first with a cognitive aid, the second without any support. Each study arm handled either a shockable or non-shockable PCA scenario, consistently across both simulations. All sessions were video-recorded and blindly reviewed by two independent raters. Statistical analysis was conducted blinded to group assignment using Stata MP version 18.5.

The results of this pilot study will inform the design of a future international multicenter study aimed at investigating the optimal integration of cognitive aids into pediatric resuscitation training.
Background: L’arresto cardiaco pediatrico (ACP) è un evento raro ma gravato da elevata morbilità e mortalità. Nonostante i progressi nella simulazione ad alta fedeltà e nella formazione PALS/EPALS, persistono criticità nella gestione ottimale delle emergenze pediatriche. I supporti cognitivi audio-visivi hanno mostrato potenziale nel migliorare le performance e ridurre gli errori in rianimazione, ma il loro ruolo nella formazione non è ancora ben definito. Scopo dello studio: L'obiettivo principale è valutare l’efficacia formativa di un supporto cognitivo audio-visivo innovativo (app PediAppRREST) rispetto al supporto tradizionale cartaceo (PALS Pocket), durante la simulazione di un ACP. In particolare, si è voluto verificare se l’uso dell’app migliorasse la performance clinica in un secondo scenario simulato, affrontato senza alcun supporto (valutazione con Clinical Performance Tool, CPT). Tra gli obiettivi secondari si trovano: Qualità e tempismo degli interventi rianimatori secondo le linee guida PALS, carico di lavoro percepito dal team leader (NASA-TLX), qualità della RCP (CPR Quality - Laerdal) e autovalutazione del consolidamento delle conoscenze (questionario ad hoc). Materiali e metodi: Studio pilota randomizzato a due bracci paralleli, con 100 medici in formazione specialistica dell’Università di Padova, suddivisi in 26 squadre da quattro membri, ciascuna con team leader certificato PALS. Le squadre sono state randomizzate in due gruppi: Intervento (uso di PediAppRREST) e Controllo (uso di PALS Pocket). Ogni squadra ha affrontato due scenari simulati consecutivi di ACP della durata di 8 minuti: il primo con supporto cognitivo, il secondo senza. Gli scenari (defibrillabili/non defibrillabili) sono stati coerenti nei due tempi. Le sessioni sono state videoregistrate e analizzate in cieco da due revisori indipendenti. Analisi statistica effettuata in cieco con Stata MP 18.5. Risultati: Il punteggio globale CPT è risultato simile nei due gruppi: PediAppRREST vs PALS Pocket (media 27,5 ± 3,3 vs 28,9 ± 2,0; p=0,2382), così come per le singole categorie. Le abilità tecniche sono state sovrapponibili, salvo due differenze: 1. Posizionamento più rapido dell’accesso vascolare con PediAppRREST (32 s vs 49 s; p=0,0138). 2. Maggiore tempestività nella richiesta di adrenalina (78 s vs 120 s; p=0,0513). Il carico di lavoro percepito è stato simile (Raw TLX: 58,1 vs 62,0; p=0,23). La qualità della RCP ha mostrato una differenza significativa a favore di PediAppRREST solo nel rilascio toracico (49,5% vs 76,7%; p=0,0364). L’autovalutazione del consolidamento delle conoscenze non ha evidenziato differenze significative tra i gruppi. Discussione e conclusioni: L’uso di PediAppRREST come supporto formativo immediato prima di una simulazione di ACP non ha mostrato superiorità rispetto a PALS Pocket in termini di performance rianimatorie, sia per valutazioni oggettive che soggettive. Alcuni benefici sono emersi su tempi di esecuzione di singole manovre, ma senza impatto complessivo significativo. I risultati di questo studio pilota saranno utili per progettare un futuro studio multicentrico volto a definire il ruolo dei supporti cognitivi nella formazione alla rianimazione pediatrica.
