Completeness and accuracy of digital charting vs paper charting in simulated pediatric cardiac arrest: a randomized controlled trial.

OBJECTIVES: To determine if data collected through digital charting are more complete and more accurate compared to traditional paper-based charting during simulated pediatric cardiac arrest. METHODS: We performed a single-center simulation-based randomized controlled trial. Participants were randomized to a novel handheld digital charting device (intervention group) or to the standard resuscitation paper chart (control group). Participants documented two 15-min simulated pediatric cardiac arrest scenarios. We compared the charting completeness between the two groups. Completeness score (primary outcome) was established by calculating a completeness score for each group based on a list of pre-determined critical tasks. Charting accuracy (secondary outcome) was compared between the two groups, defined as the time interval between the real-time task performance and charted time. RESULTS: Charting data from 34 simulated cardiac arrest events were included in the analysis (n = 18 intervention; n = 16 control). The paper charting group had a higher completeness score (median (IQR) paper vs digital: 72.0% (66.4-76.9%) vs 65.0% (58.5-66.4%), p = 0.015). For accuracy, the digital charting group was superior to the paper charting group for all pre-established critical tasks. CONCLUSION: Compared to paper-based charting, digital charting group captured more critical tasks during pediatric simulated resuscitation and was more accurate in the time intervals between real-time tasks performance and charted time. For tasks charted, paper-based charting was significantly more complete and more detailed during simulated pediatric cardiac arrest.

RéSUMé: OBJECTIFS: Déterminer si les données recueillies au moyen de la cartographie numérique sont plus complètes et plus précises que celles recueillies sur papier lors d'un arrêt cardiaque pédiatrique simulé. MéTHODES: Nous avons réalisé un essai contrôlé randomisé basé sur une simulation à centre unique. Les participants ont été affectés par randomisation à un nouvel appareil de cartographie numérique portatif (groupe d'intervention) ou au tableau papier standard de réanimation (groupe témoin). Les participants ont documenté deux scénarios simulés d'arrêt cardiaque pédiatrique de 15 min. Nous avons comparé l'exhaustivité des dossiers entre les deux groupes. Le score d'exhaustivité (résultat principal) a été établi en calculant un score d'exhaustivité pour chaque groupe en fonction d'une liste de tâches critiques prédéterminées. La précision des graphiques (résultat secondaire) a été comparée entre les deux groupes, définie comme l'intervalle de temps entre la performance de la tâche en temps réel et le temps représenté sur la carte. RéSULTATS: Les données cartographiques de 34 arrêts cardiaques simulés ont été incluses dans l'analyse (n = 18 interventions; n = 16 contrôles). Le groupe de la cartographie papier avait un score d'exhaustivité plus élevé (papier médian (IQR) que numérique: 72,0% (66,4­76,9%) contre 65,0% (58,5­66,4%), p = 0,015). Pour des raisons de précision, le groupe de cartographie numérique était supérieur au groupe de cartographie papier pour toutes les tâches critiques préétablies. CONCLUSION: Par rapport à la cartographie sur papier, le groupe de cartographie numérique a capturé des tâches plus critiques lors de la réanimation pédiatrique simulée et était plus précis dans les intervalles de temps entre les performances des tâches en temps réel et le temps cartographié. Pour les tâches cartographiées, les dossiers papier étaient significativement plus complets et plus détaillés lors de l'arrêt cardiaque pédiatrique simulé.

Data-informed debriefing for cardiopulmonary arrest: A randomized controlled trial.

Aim: To determine if data-informed debriefing, compared to a traditional debriefing, improves the process of care provided by healthcare teams during a simulated pediatric cardiac arrest. Methods: We conducted a prospective, randomized trial. Participants were randomized to a traditional debriefing or a data-informed debriefing supported by a debriefing tool. Participant teams managed a 10-minute cardiac arrest simulation case, followed by a debriefing (i.e. traditional or data-informed), and then a second cardiac arrest case. The primary outcome was the percentage of overall excellent CPR. The secondary outcomes were compliance with AHA guidelines for depth and rate, chest compression (CC) fraction, peri-shock pause duration, and time to critical interventions. Results: A total of 21 teams (84 participants) were enrolled, with data from 20 teams (80 participants) analyzed. The data-informed debriefing group was significantly better in percentage of overall excellent CPR (control vs intervention: 53.8% vs 78.7%; MD 24.9%, 95%CI: 5.4 to 44.4%, p = 0.02), guideline-compliant depth (control vs. intervention: 60.4% vs 85.8%, MD 25.4%, 95%CI: 5.5 to 45.3%, p = 0.02), CC fraction (control vs intervention: 88.6% vs 92.6, MD 4.0%, 95%CI: 0.5 to 7.4%, p = 0.03), and peri-shock pause duration (control vs intervention: 5.8 s vs 3.7 s, MD -2.1 s, 95%CI: -3.5 to -0.8 s, p = 0.004) compared to the control group. There was no significant difference in time to critical interventions between groups. Conclusion: When compared with traditional debriefing, data-informed debriefing improves CPR quality and reduces pauses in CPR during simulated cardiac arrest, with no improvement in time to critical interventions.

Aerosol Box Use in Reducing Health Care Worker Contamination During Airway Procedures (AIRWAY Study): A Simulation-Based Randomized Clinical Trial.

Importance: The aerosol box has been used during the management of patients with COVID-19 to reduce health care practitioner (HCP) exposure during aerosol-generating medical procedures (AGMPs). Little is known about the effect of aerosol box use on HCP contamination and AGMP procedure time. Objective: To investigate whether use of an aerosol box during AGMPs reduces HCP contamination or influences the time to successful completion and first-pass success rate for endotracheal intubation (ETI) and laryngeal mask airway (LMA) insertion. Design, Setting, and Participants: This multicenter, simulation-based, randomized clinical trial was conducted from May to December 2021 at tertiary care pediatric hospitals. Participant teams performed 3 simulated patient scenarios: bag-valve-mask ventilation, ETI, and LMA insertion. During the scenarios, aerosols were generated using Glo Germ. Teams of 2 HCPs were randomly assigned to control (no aerosol box) or intervention groups (aerosol box). Statistical analysis was performed from July 2022 to February 2023. Interventions: The aerosol box (or SplashGuard CG) is a transparent, plastic barrier covering the patient's head and shoulders with access ports allowing HCPs to manage the airway. Main Outcomes and Measures: The primary outcome was surface area of contamination (AOC) on participants. Secondary outcomes were time to successful completion and first-pass success rates for ETI and LMA insertion. Results: A total of 64 teams (128 participants) were enrolled, with data from 61 teams (122 participants) analyzed. Among the 122 participants analyzed, 79 (64.8%) were female and 85 (69.7%) were physicians. Use of an aerosol box was associated with a 77.5% overall decreased AOC to the torso (95% CI, -86.3% to -62.9%; P < .001) and a 60.7% overall decreased AOC to the facial area (95% CI, -75.2% to -37.8%; P < .001) in airway HCPs. There was no statistically significant difference in surface contamination after doffing personal protective equipment between groups. Time to completing ETI was longer in the aerosol box group compared with the control group (mean difference: 10.2 seconds; 95% CI, 0.2 to 20.2 seconds; P = .04), but there was no difference between groups for LMA insertion (mean difference: 2.4 seconds; 95% CI, -8.7 to 13.5 seconds; P = .67). Conclusions and Relevance: In this randomized clinical trial of aerosol box use in AGMPs, use of an aerosol box reduced contamination deposition on HCPs' torso and face predoffing; the use of an aerosol box delayed time to successful intubation. These results suggest that the incremental benefits of reduced surface contamination from aerosol box use should be weighed against delayed time to complete intubation, which may negatively affect patient outcome.

The effect of step stool use and provider height on CPR quality during pediatric cardiac arrest: A simulation-based multicentre study.

OBJECTIVES: We aimed to explore whether a) step stool use is associated with improved cardiopulmonary resuscitation (CPR) quality; b) provider adjusted height is associated with improved CPR quality; and if associations exist, c) determine whether just-in-time (JIT) CPR training and/or CPR visual feedback attenuates the effect of height and/or step stool use on CPR quality. METHODS: We analysed data from a trial of simulated cardiac arrests with three study arms: No intervention; CPR visual feedback; and JIT CPR training. Step stool use was voluntary. We explored the association between 1) step stool use and CPR quality, and 2) provider adjusted height and CPR quality. Adjusted height was defined as provider height + 23 cm (if step stool was used). Below-average height participants were ≤ gender-specific average height; the remainder were above average height. We assessed for interaction between study arm and both adjusted height and step stool use. RESULTS: One hundred twenty-four subjects participated; 1,230 30-second epochs of CPR were analysed. Step stool use was associated with improved compression depth in below-average (female, p=0.007; male, p<0.001) and above-average (female, p=0.001; male, p<0.001) height providers. There is an association between adjusted height and compression depth (p<0.001). Visual feedback attenuated the effect of height (p=0.025) on compression depth; JIT training did not (p=0.918). Visual feedback and JIT training attenuated the effect of step stool use (p<0.001) on compression depth. CONCLUSIONS: Step stool use is associated with improved compression depth regardless of height. Increased provider height is associated with improved compression depth, with visual feedback attenuating the effects of height and step stool use.

Publication of Abstracts Presented at an International Healthcare Simulation Conference.

INTRODUCTION: We aimed to determine the publication rate for abstracts presented at the International Meeting for Simulation in Healthcare (IMSH) and the time between abstract presentation and publication. We also aimed to describe the study features influencing subsequent publication and the relationship between these features and journal impact factors (IFs). METHODS: All types of accepted abstracts from the 2012 and 2013 IMSH were reviewed. We extracted the following data from each abstract in duplicate: presentation format, subject, type of scholarship, research method, study design, outcome measure, number of institutions in authorship group, and number of study sites. PubMed and Google Scholar were searched (January 1, 2012 to August 1, 2016) using the names of the first, second, and last author for comparison with abstracts. Journal of publication and IF were recorded. Data were summarized with descriptive statistics. Bivariate and multivariate analysis was performed to explore the association between publication status and other variables. RESULTS: Of 541 abstracts, 22% (119/541) were published with a median time to publication of 16 months (interquartile range = 8.525), ranging from 0 to 43 months. The study characteristics associated with a greater likelihood of publication were the following: research-type abstract, quantitative studies, randomized trials, studies with patient or healthcare-related outcomes, multiple institutions represented in authorship group, and multicenter studies. Studies with multiple institutions in authorship group and multicenter studies were published in higher IF journals (P < 0.05). CONCLUSIONS: The publication rate of 22% for abstracts presented at IMSH is low, indicative of the relatively new nature of simulation-based research in healthcare.

Effect of Emergency Department Mattress Compressibility on Chest Compression Depth Using a Standardized Cardiopulmonary Resuscitation Board, a Slider Transfer Board, and a Flat Spine Board: A Simulation-Based Study.

INTRODUCTION: Cardiopulmonary resuscitation (CPR) performed on a mattress decreases effective chest compression depth. Using a CPR board partially attenuates mattress compressibility. We aimed to determine the effect of a CPR board, a slider transfer board, a CPR board with a slider transfer board, and a flat spine board on chest compression depth with a mannequin placed on an emergency department mattress. METHODS: The study used a cross-over study design. The CPR-certified healthcare providers performed 2 minutes of compressions on a mannequin in five conditions, an emergency department mattress with: (a) no hard surface, (b) a CPR board, (c) a slider transfer board, (d) a CPR board and slider transfer board, and (e) a flat spine board. Compression depths were measured from two sources for each condition: (a) an internal device measuring sternum-to-spine compression and (b) an external device measuring sternum-to-spine compression plus mattress compression. The difference of the two measures (ie, depleted compression depth) was summarized and compared between conditions. RESULTS: A total of 10,203 individual compressions from 10 participants were analyzed. The mean depleted compression depths (percentage depletion) secondary to mattress effect were the following: 23.6 mm (29.7%) on a mattress only, 13.7 mm (19.5%) on a CPR board, 16.9 mm (23.1%) on a slider transfer board, 11.9 mm (17.3%) on a slider transfer board plus backboard, and 10.3 mm (15.4%) on a flat spine board. The differences in percentage depletion across conditions were statistically significant. CONCLUSION: Cardiopulmonary resuscitation providers should use a CPR board and slider transfer board or a flat spine board alone because these conditions are associated with the smallest amount of mattress compressibility.

Reducing the impact of intensive care unit mattress compressibility during CPR: a simulation-based study.

BACKGROUND: The depth of chest compression (CC) during cardiac arrest is associated with patient survival and good neurological outcomes. Previous studies showed that mattress compression can alter the amount of CCs given with adequate depth. We aim to quantify the amount of mattress compressibility on two types of ICU mattresses and explore the effect of memory foam mattress use and a backboard on mattress compression depth and effect of feedback source on effective compression depth. METHODS: The study utilizes a cross-sectional self-control study design. Participants working in the pediatric intensive care unit (PICU) performed 1 min of CC on a manikin in each of the following four conditions: (i) typical ICU mattress; (ii) typical ICU mattress with a CPR backboard; (iii) memory foam ICU mattress; and (iv) memory foam ICU mattress with a CPR backboard, using two different sources of real-time feedback: (a) external accelerometer sensor device measuring total compression depth and (b) internal light sensor measuring effective compression depth only. CPR quality was concurrently measured by these two devices. The differences of the two measures (mattress compression depth) were summarized and compared using multilevel linear regression models. Effective compression depths with different sources of feedback were compared with a multilevel linear regression model. RESULTS: The mean mattress compression depth varied from 24.6 to 47.7 mm, with percentage of depletion from 31.2 to 47.5%. Both use of memory foam mattress (mean difference, MD 11.7 mm, 95%CI 4.8-18.5 mm) and use of backboard (MD 11.6 mm, 95% CI 9.0-14.3 mm) significantly minimized the mattress compressibility. Use of internal light sensor as source of feedback improved effective CC depth by 7-14 mm, compared with external accelerometer sensor. CONCLUSION: Use of a memory foam mattress and CPR backboard minimizes mattress compressibility, but depletion of compression depth is still substantial. A feedback device measuring sternum-to-spine displacement can significantly improve effective compression depth on a mattress. TRIAL REGISTRATION: Not applicable. This is a mannequin-based simulation research.
