Little is known about the acquisition of intubation skills among novice physicians during their one-year clinical training. Our primary objective was to determine the changes in the intubation skills of novice physicians between prior to the clinical training and after completion of the clinical training. We used data of a prospective longitudinal multicenter data registry developed to investigate factors associated with the improvement of intubation skills among novice physicians. The study participants included 90 postgraduate year 1 physicians in 2015–2016. We used 4 simulation scenarios based on the devices used (direct laryngoscope [DL] and Airway scope [AWS]) and difficulty of intubation (normal and difficult scenarios). As a marker of the intubation skills, we used the force applied on the maxillary incisors and the tongue with each intubation. We compared the data obtained prior to clinical training with those obtained after completion of one-year clinical training. When using DL, compared to prior, significantly less force were applied on the maxillary incisors and the tongue after clinical training in the normal scenario (28.0 N vs 19.5 N, p < 0.001, and 11.1 N vs 8.4 N, p = 0.004). Likewise, when using AWS, compared to prior, significantly less force were applied on the tongue after clinical training in the normal scenario (22.0 N vs 0 N, p < 0.001). The force on the tongue decreased after clinical training but not significant. These associations persisted in the difficult airway scenario. These findings suggest that force applied on oral structures can be quantified as a marker of intubation skills by using high-fidelity simulators, and the assessment of procedural competency is recommended for all novice physicians prior to performing intubation in the clinical setting to improve the quality of emergency care.

Aim Little evidence on Japanese frequent presenters (FPs) is available. Therefore, this retrospective cohort study compared characteristics between FPs and non‐frequent presenters (NFPs) in emergency departments (EDs) in Japan. Methods Frequent presenters included those who presented to an ED ≥4 times during the study period from August 1, 2012 to July 21, 2013. The primary outcomes were triage level and disposition. Secondary outcomes were ED length of stay, method of arrival, and discharge diagnosis. Results During the study period, 195 FPs had 1,154 visits to the ED, compared to 15,953 visits by 13,838 NFPs. The sex distribution between FPs and NFPs was comparable (107 men [54.9%] versus 7,070 men [51.1%], respectively; P = 0.29), but the mean age was significantly higher in the FP group (57.3 versus 46.5 years, respectively; P < 0.0001). Among the FPs, the rate of free governmental health insurance was higher than that of those who pay 30% of health costs (35 patients paid 0% [79.5%] versus 109 patients paid 30% [42.6%], respectively). Condition severity (FP, 84 severe cases [7.28%]; NFP, 1,320 severe cases [8.27%], respectively) and rate of admission (FP, 207 admissions [17.9%]; NFP, 2,987 admissions [18.7%], respectively) were comparable between the groups, although the rate of ambulance use was lower for the FP group. The most frequent diagnostic codes (International Classification of Diseases, 10th Revision) in the FP group were “symptoms and signs”. Conclusion Triage levels and hospital admission rates were not significantly different between FPs and NFPs in this single‐center study in Japan.

ObjectiveBurnout negatively affects the wellness and performance of emergency physicians (EPs). This study aimed to clarify the actual prevalence of burnout and its associated factors among Japanese EPs.MethodsWe conducted a cross‐sectional questionnaire study of selected 27 Japanese emergency departments (EDs). We examined the Maslach Burnout Inventory‐Human Services Survey score and its associations with ED‐level‐ and EP‐level factors in a multivariable analysis.ResultsA total of 267 EPs (81.9%) completed survey. Of these, 43 EPs (16.1%) scored severe emotional exhaustion (EE), 53 (19.8%) scored severe depersonalization (DP), and 179 (67.0%) scored severe personal accomplishment (PA), and 24 (8.9%) scored severely in all three domains. In our multivariable analysis, emergency medical service centers were associated with severe PA scores (odds ratio [OR], 10.56; 95% confidence interval [CI], 1.78–62.66; p = 0.009). A 3 to 6 hour‐sleep period was associated with severe EE scores (OR, 2.04; 95% CI, 1.04–3.98; p = 0.036), and EPs in their 20s were associated with severe DP scores (OR, 7.37; 95% CI, 1.41–38.38; p = 0.018).ConclusionOur results suggest that 8.9% of Japanese EPs are in higher degrees of burnout. In particular, Japanese EPs scored more severely on PA. To avoid burnout in Japanese EPs, it is important to improve the working environment by ensuring more than 6 h of sleep, providing more support for young EPs, and taking effective action to combat low EP self‐esteem.

BackgroundAfter the coronavirus disease (COVID‐19) pandemic, nationwide school closures were implemented in many countries. This study aimed to determine the impact of the school closures on pediatric ambulance transport, comparing the situation before and after the COVID‐19 pandemic.MethodsThis retrospective observational study was conducted using data from the Kochi‐Iryo.net database. In Kochi prefecture, schools were closed from March 6 to May 24, 2020. Pediatric emergency transport during the school closure period in 2020 was compared with that in the same period in 2019 (before the COVID‐19 pandemic) and in 2021 (when schools were not closed). Statistical analysis comprised χ2 tests with Bonferroni adjustments for multiple testing. To adjust for patient backgrounds, we also performed multiple logistic regression analyses for numbers of pediatric ambulance transports.ResultsThe rate of pediatric ambulance transports was significantly lower (p = 0.008) in 2020 (276; 3.97%) than in 2019 (391; 4.87%), but there was no significant difference (p = 0.360) between 2019 (391; 4.87%) and 2021 (352; 4.56%). Multivariable analysis revealed similar trends (2019 vs. 2020: OR 0.86, 95% CI 0.73–1.00; 2019 vs. 2021: OR 0.96, 95% CI 0.82–1.11). Regarding the characteristics of pediatric ambulance transport journeys, there were no significant differences in 2019, 2020, and 2021 in terms of sex, severity, locations of ambulance stations, and disease classification.ConclusionsThere was a decrease in pediatric ambulance transportation due to the public health interventions for COVID‐19, including school closures. However, this decrease was not solely due to school closures.
