The factors influencing the outcomes of mild/moderate acute subdural hematoma (ASDH) are still unclear. Retrospective analyses were performed to identify such factors. The medical records of all patients who were admitted to Saiseikai Shiga Hospital with mild (Glasgow Coma Scale [GCS] score of 14–15) or moderate (GCS score of 9–13) ASDH between April 2008 and March 2017 were reviewed. Comparisons between the patients who exhibited favorable and poor outcomes were performed. Then, independent factors that contributed to poor outcomes were identified via logistic regression analyses. A total of 266 patients with a mean age of 70.2 were included in this study. The most common concomitant injuries were subarachnoid hemorrhages (SAHs; 56.8%). The patients’ Injury Severity Scores (ISS) ranged from 16 to 75 (median: 21). The 66 moderate ASDH patients exhibited significantly higher frequencies of surgery and mortality (24.2% and 13.6%, respectively) than the 200 mild ASDH patients (8.0% and 4.5%, respectively). The factors associated with poor outcomes were age (odds ratio [OR]: 1.06) and the ISS (OR: 1.24) in the mild ASDH patients, and older age (OR: 1.09) and the higher ISS (OR: 1.15) in the moderate group, too.

Sudden illness while driving has been identified as a major cause of vehicle collisions, particularly among taxi drivers. However, no previous studies have examined the factors contributing to the occurrence of health-related vehicle collisions. The current study aimed to identify the risk factors causing health-related vehicle collisions among taxi drivers, and to inform preventative interventions. A cross-sectional survey involving a written anonymous questionnaire was conducted for company-employed taxi drivers in Chiba Prefecture, Japan. A total of 1,739 drivers returned questionnaires. Drivers were classified into those who had experienced collisions or near-miss incidents caused by health problems (Event group), and those who had not (Non-event group). According to a multivariable logistic regression analysis, being unable to take vacation time (odds ratio [OR] 4.59, 95% confidence interval [CI] 2.2–9.58), having chronic diseases (OR 1.52, 95% CI 1.02–2.27), taking insufficient vacation time (OR 1.81, 95% CI 1.19–2.79), and difficulty reporting poor health conditions (OR 2.29, 95% CI 1.36–3.87) were significant factors for the likelihood of an event. Support for drivers to maintain well-balanced control of illnesses and improvement of working environments could prevent health-related events while driving.
