RESUMO
Objective: Burnout 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. Methods: We 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. Results: A 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). Conclusion: Our 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.
RESUMO
BACKGROUND: After 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. METHODS: This 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. RESULTS: The 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. CONCLUSIONS: There 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.

BACKGROUND: Anaphylaxis is a severe, potentially fatal, systemic allergic reaction. But its real-world evidence is limited. Both treatment of allergic symptoms and prevention of future anaphylactic episodes are clinically important. We have strongly recommended that patients visit our outpatient allergy clinic. OBJECTIVE: To classify the clinical features and triggers of anaphylaxis in patients (≥16 years old) in an urban area of Tokyo. METHODS: We used the medical records to analyze patients with anaphylaxis as the primary diagnosis who visited the emergency department in our hospital from January 2015 through December 2017. RESULTS: Among approximately 60000 patients who visited the emergency department, 181 subjects (mean age, 43.0; 44% male) were diagnosed with anaphylaxis. Fourteen of those patients had a systolic blood pressure of lower than 90mmHg. Upon arrival, 126 patients were treated with adrenaline. All patients recovered from the anaphylactic episode. Subsequently, 133 patients visited our outpatient allergy clinic. The trigger of the anaphylaxis were assessed; the most popular trigger was foods (n = 78), followed by drugs (n = 38), insect stings/bites or animal bites (n = 3) and others (n = 11). Adrenaline auto-injectors were prescribed to 84 patients. CONCLUSION: It is important for patients with anaphylaxis to undergo allergy testing after discharge from an emergency department. Collaboration between emergency medicine and allergy departments may be helpful for improving the patients' QOL through effective instruction and prevention of recurrent anaphylaxis.

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.
RESUMO
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.

The concentration of polycyclic aromatic hydrocarbons (PAHs) and the toxicity to marine bacteria (Vibrio fischeri) were measured for the organic solvent extracts of sea sediments collected from an urban watershed area (Hiroshima Bay) of Japan and compared with the concentrations and toxicity of atmospheric particulate matter (PM). In atmospheric PM, the PAHs concentration was highest in fine particulate matter (FPM) collected during cold seasons. The concentrations of sea sediments were 0.01-0.001 times those of atmospheric PM. 1/EC50 was 1-10 L g(-1) PM for atmospheric PM and 0.1-1 L g(-1) dry solids for sea sediments. These results imply that toxic substances from atmospheric PM are diluted several tens or hundreds of times in sea sediments. The ratio of the 1/EC50 to PAHs concentration ((1/EC50)/16PAHs) was stable for all sea sediments (0.1-1 L µg(-1) 16PAHs) and was the same order of magnitude as that of FPM and coarse particulate matter (CPM). The ratio of sediments collected from the west was more similar to that of CPM while that from the east was more similar to FPM, possibly because of hydraulic differences among water bodies. The PAHs concentration pattern analyses (principal component analysis and isomer ratio analysis) were conducted and the results showed that the PAHs pattern in sea sediments was quite different to that of FPM and CPM. Comparison with previously conducted PAHs analyses suggested that biomass burning residues comprised a major portion of these other sources.
