Foreign Patients Visiting the Emergency Department: A Systematic Review of Studies in Japan.

Background: As the number of non-native patients in Japan is increasing, emergency departments must provide proper care for international patients. However, no research has been conducted to determine the demographics of international patients that visit Japanese hospitals or the requirements to accept them. We aimed to organize the existing research and its patterns for foreign patients in Japan's emergency departments and to identify the areas that require further research. Methods: Systematic review of research articles indexed in MEDLINE and Ichushi-web (Japanese medical literature) was conducted. The search strategy was based on a previous study in Japanese, and the search was limited to manuscripts published from 2015. Results: Nine publications that reported on the demographic characteristics of foreign patients who visited the emergency department were among the study's 13 references. Injury diagnoses and the Asian population were both common. Dealing with overseas patients can be challenging due to linguistic barriers, cultural differences, and payment issues. However, studies describing the spoken language and the type of healthcare insurance used were lacking. Furthermore, neither the definition of "foreign patients" nor the distinction between short-term visitors and long-term residents were made in the majority of the research. Conclusions: The demographic characteristics of patients differed depending on the location and facility, despite the fact that several characteristics of foreign patients in emergency departments appeared to be generalizable. The COVID-19 pandemic may modify the demographic characteristics of immigrants; thus, more research from a broad range of locations and medical facilities is still necessary.

Traumatic retropharyngeal hematoma without spinal cord injury or spinal fracture: a retrospective multicenter analysis.

BACKGROUND: Retropharyngeal hematoma can be a life-threatening injury due to progressive upper airway obstruction. It is common following spinal cord injury or spinal fracture, and the clinical course and outcome of such patients are determined by their primary injuries. However, the natural clinical course of retropharyngeal hematoma itself remains unclear. In this study, we aimed to examine the clinical characteristics of traumatic retropharyngeal hematoma without spinal cord injury or spinal fracture (TREWISS). METHODS: We performed a multicenter retrospective analysis of patients who were diagnosed in the emergency department with soft tissue swelling of the retropharyngeal space by neck CT, between April 2010 and April 2020. The inclusion criterion was thickness of the retropharyngeal space > 7 mm at C1-C4 or > 22 mm at C5-C7 on a CT image. The exclusion criteria were (1) age < 18 years, (2) cardiopulmonary arrest, (3) other causes of soft tissue swelling besides hematoma, (4) patients with cervical spinal cord injury or spine fractures. Baseline characteristics were compared between intubated and non-intubated patients. RESULTS: Twenty-two patients were included in the analysis. Among them, 16 patients needed intubation. Median patient age was 69 years, and 27% of the patients were on antiplatelet or anticoagulant medications. The width of the hematoma on sagittal CT images was significantly wider in the intubated group [median (interquartile range), 2.5 cm (2.0-3.4) vs. 1.2 cm (0.9-1.7), p = 0.002). More than half the intubated patients needed tracheotomy. Tracheotomy was performed around day 3, and endotracheal tube was placed about 3 weeks. Only 60% of patients were successfully discharged to their homes, and one patient (6.3%) died during hospitalization. CONCLUSION: Early intubation and subsequent intensive care are important for patients with TREWISS. The patients typically require several weeks of hospitalization, although their outcomes are usually poor.

Fluid resuscitation of at least 30 mL/kg was not associated with decreased mortality in patients with infection, signs of hypoperfusion, and a do-not-intubate order.

Aim: Administration of at least 30 mL/kg of fluid as fluid resuscitation is recommended for patients with sepsis and signs of hypoperfusion. However, it is not clear whether this is appropriate for patients with a do-not-intubate (DNI) order. This study evaluated the association between volume of fluid resuscitation and outcomes in patients with infection, signs of hypoperfusion, and a DNI order in an emergency department. Methods: This was a single-center retrospective cohort study. We classified the infected patients with signs of hypoperfusion and a DNI order seen in our emergency department between April 1, 2015 and November 31, 2020 into the standard fluid resuscitation group (≥30 mL/kg) and the restricted fluid resuscitation group (<30 mL/kg). We compared with in-hospital mortality and the rate of discharge to home in two groups. Results: Of 367 patients, 149 received standard fluid resuscitation and 218 received restricted fluid resuscitation. In-hospital mortality was similar in each group (40/149 and 62/218, respectively). Standard fluid resuscitation was not associated with in-hospital mortality (adjusted odds ratio [aOR], 1.05; 95% confidence interval [CI], 0.62-1.77, P = 0.86), but was associated with a significantly lower rate of discharge to home (aOR, 0.55; 95% CI, 0.30-0.98, P = 0.043). There was no significant difference in respiratory rate or need for oxygen therapy post-resuscitation between the two groups. Conclusion: This study suggests that fluid resuscitation may be not beneficial for infected patients with signs of hypoperfusion and a DNI order. Further studies should be conducted on the options for resuscitation management for these patients.

Foreign patients in emergency departments of Japanese medical facilities.

Our manuscript is a letter to the article "Factors associated with emergency department length of stay of foreign patients visiting a regional core hospital in Japan." by Aoki et al. published ahead of print in Acute Medicine and Surgery. We believe that the manuscript by Aoki et al. is the first publication to suggest that linguistics play an important role in the outcomes of foreign patients in Japanese medical facilities, and applaud them for their contribution. However, we also believe that further assessments are required to make their implications more robust. Therefore, in our manuscript, we would like to highlight several criteria that should be included in such studies, derived from studies that have been conducted under similar situations in Japanese medical facilities.

Autopsy findings of a patient with severe COVID-19 treated with long-term extracorporeal membrane oxygenation.

Extracorporeal membrane oxygenation (ECMO) therapy in patients with coronavirus disease 2019 (COVID-19) has a low frequency of use, and thus pathological findings in such patients are valuable. In this case report, a 62-year-old man with a history of hypertension presented with a runny nose. After an at-home COVID-19 positive test, he developed dyspnea and fever. Once admitted to our hospital, his oxygenation worsened, and ECMO was initiated. He died from respiratory failure 69 days after ECMO induction. Macroscopically, the lungs gained mass, were partially consolidated, and were airless. Histological analysis revealed diffuse bronchial epithelial metaplasia and adenoid metaplasia in the alveolar epithelium. Although the lung parenchyma was partially preserved, there was organizing and fibrosis that filled pulmonary alveolus due to COVID-19 and changes resulting from disuse and long-term ECMO.
