RESUMO
BACKGROUND: The lower clinical exposure of Pediatric Emergency Medicine (PEM) fellows to critical procedures may impede skill acquisition. We sought to determine the tracheal intubation learning curve of PEM fellows during training and compared PEM fellow success against standards for tracheal intubation success. METHODS: This was a retrospective, video-based study of a cohort of PEM fellows at a single academic pediatric emergency department (PED). All forms of tracheal intubation were included (rapid sequence intubation and crash or no medication). The cohort consisted of 36 PEM fellows from all or part of 5 consecutive fellowship classes. Data were collected by structured review of both existing ceiling-mounted videos and the electronic medical record. The main outcome was PEM fellows' success on the first or second attempt. We used cumulative summation to generate tracheal intubation learning curves. We specifically assessed the proportion of PEM fellows who reached 1 of 4 thresholds for procedural performance: 90% and 80% predicted success on the first and the first or second attempt. RESULTS: From July 2014 to June 2020, there were 610 patient encounters with at least 1 attempt at tracheal intubation. The 36 PEM fellows performed at least 1 attempt at tracheal intubation for 414 ED patient encounters (65%). Median patient age was 2.1 years (interquartile range, 0.4-8.1). The PEM fellows were successful on the first attempt for 276 patients (67%) and on the first or second attempt for 337 (81%). None of the 36 PEM fellows reached the 90% threshold for either first or second attempt success. Four fellows (11%) met the 80% threshold for first attempt success and 11 (31%) met the 80% threshold for first or second attempt success. CONCLUSIONS: Despite performing the majority of attempts, PEM fellows often failed to reach the standard thresholds for performance of tracheal intubation. Clinical exposure alone is too low to ensure acquisition of airway skills.
RESUMO
BACKGROUND: Pulse oximetry (SpO2) is a flawed measure of adequacy of preoxygenation prior to intubation. The fraction of expired oxygen (FeO2) is a promising but understudied alternative. OBJECTIVE: To investigate FeO2 as a measure of preoxygenation prior to intubation in a pediatric emergency department. METHODS: We conducted a prospective, observational study of patients 18 and younger. We collected data using video review, and FeO2 was measured via inline sampling. The main outcomes were FeO2 and SpO2 at the start of preoxygenation, end of preoxygenation/start of intubation attempt, and the end of intubation attempt. We compared FeO2 and SpO2 at the end of preoxygenation for patients with and without oxyhemoglobin desaturation. RESULTS: We enrolled 85 of 88 eligible patients during the 14-month study period. FeO2 data were available at the start of preoxygenation for 53 of 85 patients (62%), and for the end of preoxygenation for 59 of 85 patients (69%). Median FeO2 at the start and end of preoxygenation was 90% (interquartile range [IQR] 88, 92) and 90% (IQR 88, 92). Median SpO2 at the start and end of preoxygenation was 100% (IQR 100, 100). There were 11 episodes of desaturation, with median FeO2 at the start of intubation attempt of 89.5 (IQR 54.5, 91.5) and median SpO2 of 100 (IQR 99, 100). Patients who did not have a desaturation event had a median FeO2 of 90.0 (IQR 88.0, 92.0). CONCLUSIONS: Measuring FeO2 during rapid sequence intubation is challenging with feasibility limitations, but may be a more discriminatory metric of adequate preoxygenation.

OBJECTIVE: Develop a framework for data collection to determine the contributions of both laryngoscopy and tube delivery intervals to the apneic period in unsuccessful and successful attempts among patients undergoing rapid sequence intubation (RSI) in a pediatric emergency department (PED). DESIGN: This was a retrospective, observational study of RSI. SETTING: An academic PED. PATIENTS: A consecutive sample of all intubations attempts of first provider physicians performing RSI in the shock trauma suite over a 10-month period in 2018-2019. MEASUREMENT AND MAIN RESULTS: Data were collected by structured video review. The main outcome was the duration of the laryngoscopy and tube delivery intervals per attempt. We compared interval duration between successful and unsuccessful attempts, adjusting for age, accounting for repeated measures, and clustering by provider. There were 69 patients with 89 total intubation attempts. Sixty-three patients were successfully intubated by the first provider (91%). Pediatric emergency medicine fellows performed 54% of the attempts. The median duration of the apneic period per attempt was longer in unsuccessful attempts (57 vs 44 seconds; median of difference, -10.5; 95% confidence interval [CI], -17.0 to -4.0). The duration of laryngoscopy was similar (18 vs 13 seconds; median of difference, -3.5; 95% CI, -8.0 to 1.0), but tube delivery was longer in unsuccessful attempts (25.5 vs. 11 seconds; median of difference, -12.5; 95% CI, -17.0 to -4.0). These results did not change when adjusting for age or clustering by provider. CONCLUSIONS: We successfully developed a specific, time-based framework for the contributors to prolonged apnea in RSI. Prolonged tube delivery accounted for more of the apneic period. Future studies and improvement should focus on problems during tube delivery in the PED.

Objective: The study objective was to determine the effect of a rapid cycle deliberate practice (RCDP) program on simulated and actual airway skills by pediatric emergency medicine (PEM) fellows. Methods: We designed and implemented a 12-month RCDP airway skills curriculum for PEM fellows at an academic pediatric institution. The curriculum was designed using airway training literature, RCDP principals, and internal quality assurance airway video review program. Simulation training scenarios increased in complexity throughout the curriculum. PEM fellows participated in monthly sessions. Two PEM faculty facilitated the sessions, utilizing a step-by-step objective structured clinical evaluation (OSCE)-style tool for each scenario. Data were collected for all four levels of the Kirkpatrick Model of Training Evaluation-participant response (reaction, pre-post session survey), skills performance in the simulation setting (learning, pre-post OSCE), skills performance for actual patients (behavior, video review), and patient outcomes (results, video review). Results: During the study period (August 2021 to June 2022), 13 PEM fellows participated in 112 sessions (mean nine sessions per fellow). PEM fellows reported improved comfort in all domains of airway management, including intubation performance. Participant OSCE scores improved posttraining (pretraining median score for trainees 57 [IQR 57-59], posttraining median 61 [IQR 61-62], p = 0.0005). Over the 12 months, PEM fellows performed 45 intubation attempts in the pediatric emergency department (median patient age 4 years [IQR 1-9 years]). Compared to a 5-year historical cohort, participants had higher first-pass success (87% vs. 71%, p = 0.028) and shorter attempt duration (22 s vs. 29 s, p = 0.018). There was no significant difference in the frequency of oxyhemoglobin desaturation in the training period versus the historical period (7% vs. 15%, p = 0.231). Conclusions: At multiple levels of educational outcomes, including participant behavior and patient outcomes, an RCDP program was associated with improved airway skills and performance of PEM fellows.
RESUMO
Many quality improvement interventions do not lead to sustained improvement, and the sustainability of healthcare interventions remains understudied. We conducted a time-series analysis to determine whether improvements in the safety of rapid sequence intubation (RSI) in our academic pediatric emergency department were sustained 5 years after a quality improvement initiative. METHODS: There were 3 study periods: baseline (April 2009-March 2010), improvement (July 2012-December 2013), and operational (January 2014-December 2018). All patients undergoing RSI were eligible. We collected data using a structured video review. We compared key processes and outcomes with statistical process control charts. RESULTS: We collected data for 615 of 643 (96%) patient encounters with RSI performed: 114 baseline (12 months), 105 improvement (18 months), and 396 operational (60 months). Key characteristics were similar, including patient age. Statistical process control charts indicated sustained improvement of all 6 key processes and the primary outcome measure (oxyhemoglobin desaturation) throughout the 5-year operational period. CONCLUSIONS: Improvements in RSI safety were sustained 5 years after a successful improvement initiative, with further improvement seen in several key processes. Further research is needed to elucidate the factors contributing to sustainability.
