BackgroundFrequent and repeated visits from patients with mental illness or free medical care recipients may elicit physicians’ negative emotions and influence their clinical decision making. This study investigated the impact of the psychiatric or social background of such patients on physicians’ decision making about whether to offer recommendations for further examinations and whether they expressed an appropriate disposition toward the patient.MethodsA randomized, controlled multi-centre study of residents in transitional, internal medicine, or emergency medicine was conducted in five hospitals. Upon randomization, participants were stratified by gender and postgraduate year, and they were allocated to scenario set 1 or 2. They answered questions pertaining to decision-making based on eight clinical vignettes. Half of the eight vignettes presented to scenario set 1 included additional patient information, such as that the patient had a past medical history of schizophrenia or that the patient was a recipient of free care who made frequent visits to the doctor (biased vignettes). The other half included no additional information (neutral vignettes). For scenario set 2, the four biased vignettes presented to scenario set 1 were neutralized, and the four neutral vignettes were rendered biased by providing additional information. After reading, participants answered decision-making questions regarding diagnostic examination, interventions, or patient disposition. The primary analysis was a repeated-measures ANOVA on the mean management accuracy score, with patient background information as a within-subject factor (no bias, free care recipients, or history of schizophrenia).ResultsA total of 207 questionnaires were collected. Repeated-measures ANOVA showed that additional background information had influence on mean accuracy score (F(7, 206) = 13.84, p <  0.001 partial η2 = 0.063). Post hoc pairwise multiple comparison test, Sidak test, showed a significant difference between schizophrenia and no bias condition (p <  0.05). The ratings for patient likability were lower in the biased vignettes compared to the neutral vignettes, which was associated with the lower utilization of medical resources by the physicians.ConclusionsAdditional background information on past medical history of schizophrenia increased physicians’ mistakes in decision making. Patients’ psychiatric backgrounds should not bias physicians’ decision-making. Based on these findings, physicians are recommended to avoid being influenced by medically unrelated information.

Background: Several countries have imposed a mandatory 14-day period of quarantine on individuals arriving from countries considered high-risk for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection. However, it is not clear how long asymptomatic patients infected with SARS-CoV-2 can be an asymptomatic carrier. Case Presentation: We experienced a case of an asymptomatic female patient infected with SARS-CoV-2 with abnormal chest computed tomography findings. She did not develop a fever during hospitalized isolation. She remained reverse transcription-polymerase chain reaction-positive for 24 days. Conclusion: An asymptomatic patient diagnosed with SARS-CoV-2 infection remained reverse transcription-polymerase chain reaction-positive for 24 days, although she was quarantined in an isolation hospital. This finding suggests that an asymptomatic patient diagnosed with SARS-CoV-2 infection with abnormal chest computed tomography findings can be an asymptomatic carrier for more than 3 weeks.

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.
