Oesophageal coins invisible on chest radiography: a case report

Abstract Background Coins are made of metal, which is generally radiopaque, and so physicians often have the misconception that all coins are detectable by radiography. Here, we report a case of intentionally swallowed coins in the oesophagus of an adult; the coins could not be detected on chest radiography but were detected using computed tomography (CT). Case presentation A 46-year-old woman with a history of depression presented to the emergency department after an intentional medication overdose and ingestion of two Japanese 1-yen coins. She complained of persistent retrosternal discomfort. In order to confirm whether the coins were in the oesophagus or trachea, an anteroposterior chest radiograph was obtained; however, no coins were detected. Owing to her persistent symptoms, a chest CT was performed. On the initial CT scan, two 1-yen coins were observed in the oesophagus: one in the middle oesophagus and the other in the lower oesophagus. After the scanning, the patient drank water with permission, but vomited. No coins were found in her vomit, and the symptoms of retrosternal discomfort had completely disappeared. A subsequent CT scan revealed that the two 1-yen coins were in the patient’s stomach. Conclusions Japanese 1-yen coins are made of 100% aluminium, which is less radiopaque than the metals that make up coins (nickel, bronze, and lead), and so, they were not visible via chest radiography in our case. Detecting very small or thin radiolucent foreign bodies is not possible using a chest radiograph or contrast oesophagram, but is possible via CT. CT is both increasingly convenient and non-invasive, unlike endoscopy or bronchoscopy, and so, the use of CT scans should be considered in cases of possible radiolucent foreign body ingestion

Factors for delays in door-to-balloon time ≤ 90 min in an electrocardiogram triage system among patients with ST-segment elevation myocardial infarction: a retrospective study

Abstract Background Door to balloon time is a crucial factor of mortality in patients with ST-segment elevation myocardial infarction. However, the factors that contribute to failure of achieving door to balloon time ≤ 90 min in an electrocardiogram triage system remain unknown. Methods This single-center retrospective observational study collected data from consecutive patients with ST-segment elevation myocardial infarction from April 2016 to March 2021. The primary outcome was the failure to achieve door to balloon time ≤ 90 min. A multivariate logistic regression model was performed to predict factors associated with failure to achieve door to balloon time ≤ 90 min. Results In total, 190 eligible patients were included. Of these, the 139 (73.2%) patients with door to balloon time ≤ 90 min were significantly younger compared to those with door to balloon time > 90 min (p = 0.02). However, there was no significant difference in sex and timing of hospital arrival between the door to balloon time ≤ 90 and > 90 min groups. Presence of chest pain and ambulance usage were significantly more frequent in patients with door to balloon time ≤ 90 min (p ≤ 0.01, p = 0.02, respectively). Multivariate analysis showed that absence of chest pain (adjusted odds ratio 4.76; 95% confidence interval, 2.04–11.1; p < 0.01) and non-ambulance usage (adjusted odds ratio 3.53; 95% confidence interval, 1.57–7.94; p < 0.01) are predictive factors of failure to achieve door to balloon time ≤ 90 min. Conclusion Patients without chest pain as the chief complaint or non-ambulance usage were significantly associated with the failure to achieve door to balloon time ≤ 90 min

Association between capnography and recovery time after procedural sedation and analgesia in the emergency department

Abstract Aim Capnography is recommended for use in procedural sedation and analgesia (PSA); however, limited studies assess its impact on recovery time. We investigated the association between capnography and the recovery time of PSA in the emergency department (ED). Methods This study was a secondary analysis of a multicenter PSA patient registry including eight hospitals in Japan. We included all patients who received PSA in the ED between May 2017 and May 2021 and divided the patients into capnography and no‐capnography groups. The primary outcome was recovery time, defined as the time from the end of the procedure to the cessation of monitoring. The log‐rank test and multivariable analysis using clustering for institutions were performed. Results Of the 1265 screened patients, 943 patients who received PSA were enrolled and categorized into the capnography (n = 150, 16%) and no‐capnography (n = 793, 84%) groups. The median recovery time was 40 (interquartile range [IQR]: 25–63) min in the capnography group and 30 (IQR: 14–55) min in the no‐capnography group. In the log‐rank test, the recovery time was significantly longer in the capnography group (p = 0.03) than in the no‐capnography group. In the multivariable analysis, recovery time did not differ between the two groups (adjusted hazard ratio, 0.95; 95% confidence interval, 0.77–1.17; p = 0.61). Conclusion In this secondary analysis of the multicenter registry of PSA in Japan, capnography use did not associate with shorter recovery time in the ED

Burnout among Japanese emergency medicine physicians: A multicentric questionnaire study

Abstract 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

Emergency department outpatient treatment of alcohol-intoxicated bicyclists increases the cost of medical care in Japan.

Riding a bicycle under the influence of alcohol is illegal in Japan. Nevertheless, intoxicated bicyclists are frequently treated at hospital emergency departments for bicycle-related injuries. This patient population usually requires more hospital resources, even for relatively minor injuries. Therefore, we hypothesized that bicycle-related crashes involving bicyclists under the influence of alcohol cost more to treat than those that do not involve alcohol intoxication. The aim of the present study was to examine the costs associated with bicycle-related minor injuries and alcohol intoxication of the bicyclist. The study was conducted at the Tokyo Bay Urayasu Ichikawa Medical Center Emergency Department, Japan. All minor bicycle crashes involving 217 individuals aged ≥20 years treated from September 1, 2012 to August 31, 2013 were included in the analysis of data obtained from medical records. Variables included alcohol intoxication, sex, age, collision with a motor vehicle, Glasgow Coma Scale, injury severity score (ISS), laboratory tests, treatment of wounds, number of X-ray images, number of computed tomography scans, and medical costs. Multiple linear regression analysis was performed to evaluate the association between alcohol intoxication and medical costs. Seventy (32%) patients consumed alcohol, and the median medical cost was 253 USD (interquartile range [IQR], 164-330). Multivariable analysis showed that alcohol intoxication was independently associated with higher medical costs (p = 0.030, adjusted R-square value = 0.55). These findings support our hypothesis and should encourage authorities to implement comprehensive measures to prohibit bicycling under the influence of alcohol to prevent injuries and to reduce medical costs

Comparison of professionalism between emergency medicine resident physicians and faculty physicians: A multicenter cross-sectional study.

Professionalism is a critical competency for emergency medicine (EM) physicians, and professional behavior affects patient satisfaction. However, the findings of various studies indicate that there are differences in the interpretation of professionalism among EM resident physicians and faculty physicians. Using a cross-sectional survey, we aimed to analyze common challenges to medical professionalism for Japanese EM physicians and survey the extent of professionalism coursework completed during undergraduate medical education. We conducted a multicenter cross-sectional survey of EM resident physicians and faculty physicians at academic conferences and eight teaching hospitals in Japan using the questionnaire by Barry and colleagues. We analyzed the frequency of providing either the best or second-best answers to each scenario as the main outcome measure and compared the frequencies between EM resident physicians and EM faculty physicians. Fisher's exact test and the Wilcoxon rank sum test were used to analyze data. A total of 176 physicians (86 EM resident physicians and 90 EM faculty physicians) completed the survey. The response rate was 92.6%. The most challenging scenario presented to participants dealt with sexual harassment, and only 44.5% chose the best or second-best answers, followed by poor responses to the confidentiality scenario (69.9%). The frequency of either the best or second-best responses to the confidentiality scenario was significantly greater for EM resident physicians than for EM faculty physicians (77.1% versus 62.9%, p = 0.048). More participants in the EM resident physician group completed formal courses in medical professionalism than those in the EM faculty physician group (25.8% versus 5.5%, p < 0.01). Further, EM faculty physicians were less likely than EM resident physicians to provide acceptable responses in terms of confidentiality, and few of both had received professionalism training through school curricula. Continuous professionalism education focused on the prevention of sexual harassment and gender gap is needed for both EM resident physicians and faculty physicians in Japan
