Factors associated with emergency department length of stay of foreign patients visiting a regional core hospital in Japan.

Aim: This study aims to elucidate the foreign patient-specific factors associated with emergency department length of stay (EDLOS) in a regional core hospital emergency department (ED) in Japan. Methods: This retrospective observational study included non-Japanese patients who visited the ED in a Japanese regional core hospital between April 1, 2018, and March 31, 2020. The effects on EDLOS were assessed using multivariate linear regression analysis, which included factors such as age, sex, consultation language, interpreter usage, arrival time, day of visit, mode of arrival, underlying disease, triage level, diagnosis of injury/noninjury, diagnostic investigations, consultation with specialists, and treatments or procedures. Results: Of 65,297 ED patients, there were 777 study patients, with a median age of 37 years (interquartile range [IQR], 24.0-50.0). The median EDLOS was 101 min (IQR, 63.0-153.0). Multivariate linear regression analysis indicated that an extended EDLOS was associated with: language apart from Japanese, Chinese, or English (51.7 min; 95% confidence interval [CI], 17.8-85.6), helicopter arrival (115.6 min; 95% CI, 48.8-182.5), blood testing (60.5 min; 95% CI, 34.6-86.4), computed tomography (23.8 min; 95% CI, 3.7-43.9), consultation with specialists (36.2 min; 95% CI, 11.8-60.6), intravenous fluid/medication (29.7 min; 95% CI, 3.3-56.1), and surgical procedure/reduction/fixation in the ED (38.8 min; 95% CI, 14.2-63.4). Conclusions: Consultation in a language other than Japanese, English, or Chinese was associated with a longer EDLOS in a regional core hospital in Japan. Devising ways to accommodate patients who speak various languages could be important.

Association between underlying disease and serious events on a world cruise ship: A prospective cohort study.

BACKGROUND: This study aimed to clarify the effects of underlying diseases on clinical outcomes of patients aboard a world cruise ship. METHODS: This prospective cohort study included patients who sought physician consultations at an onboard clinic on a 105-day world cruise (September-December 201X) on a ship chartered by a Japanese travel agency. Multivariable logistic regression analysis was performed to ascertain whether any concurrent disease, such as hypertension, was associated with additional onboard treatment by the primary physician or serious events, including unexpected final disembarkation, temporary disembarkation for hospitalization ashore, shore-side referral, and onboard clinic admission. RESULTS: Of 313 patients, 182 (58%) had at least one underlying disease. Sixty-eight (22%) required additional treatment, and 24 (8%) experienced serious events. After adjusting for age, sex, and underlying diseases, the 60-69- and 70-74-year age groups had a lower risk of serious events than the ≤59-year age group (odds ratio [OR], 95% confidence interval [CI]: 0.24, 0.069-0.81; p = 0.022 and 0.045, 0.0051-0.47; p = 0.0055). Underlying disease was associated with serious events (OR, 95% CI: 3.2, 1.1-9.5; p = 0.036). CONCLUSIONS: Unexpected events can occur in patients on world cruises regardless of age. Preexisting diseases may confer higher risk of serious events.

A study of the usefulness of inspection of radiology reports in the emergency room.

AIM: The aim of this study was to better understand the usefulness of retrospective inspection of radiology reports of CT (computed tomography) or MRI (magnetic resonance imaging) by emergency doctors in the emergency room. METHODS: Between April 2018 and March 2019, patients who went home after CT or MRI who needed to change their treatment plans and subsequent corresponding procedures after inspection of radiology reports by emergency doctors were reviewed. RESULTS: Among 7,661 CT or MRIs performed on 5,917 patients, there were 131 patients (133 CT or MRI or 1.7% among 7,661 examinations) who required a change in their treatment plans after inspection of radiology reports. Of the 133 CT or MRI performed, there were 51 (38.3% among 133 CT or MRI, 0.7% among 7,661 examinations) CT or MRI performed, which indicated findings to suspect a tumor (11.8% in the head, 41.2% in the chest, 35.3% in the abdomen, and 11.8% in others). With the need to make important changes in treatment plans, making appointments for outpatient clinics was necessary for 52 CT or MRI findings, and requiring the patients to return to the clinic or be admitted was necessary for 9 (totally 61; 0.8% among 7,661 examinations). CONCLUSION: Data from this study suggest that inspection of radiology reports of CT or MRI by emergency doctors after patients went home is useful in finding characteristics suggestive of tumors in 0.7% of all radiology reports and is necessary to identify important changes that should be made in treatment plans in 0.8% of all radiology reports.
