Purpose
Recently, a sharp increase in the use of delivery services has led to an increase in motorcycle accidents. This study aimed to identify the characteristics of the commercial motorcycle injured patients and factors related to the severity during the past 10 years.
Methods
Patients (15–64 years old) who visited the emergency department with commercial motorcycle accidents injury registered in the Korean Emergency Department-based Injury In-depth Surveillance (2011–2020) database, were included. All included cases were categorized into two groups according to the period: group 1 (2011–2015) and group 2 (2016–2020). General characteristics and the factors associated with severity were investigated.
Results
Among 8,123 emergency department visits, patients in group 1 were 3,071, and patients in group 2 were 5,052. The odds for severity were affected by patients age (odds ratio [OR], 1.008; 95% confidence interval [CI], 1.004–1.013), and overnight/morning (00:00–12:00; OR, 1.243; 95% CI, 1.091–1.415). The odds for severity were higher in head and neck injury (OR, 8.357; 95% CI, 7.410–9.424) and torso injury (OR, 4.122; 95% CI, 3.610–4.708). The odds for the severity of accidents based on excess mortality ratio-adjusted Injury Severity Score (EMR-ISS) after 2015 were significant (OR, 1.491; 95% CI, 1.318–1.687). Hospitalization in the intensive care unit and death were associated with accidents after 2015 (OR, 2.593; 95% CI, 2.120–3.170).
Conclusions
Commercial motorcycle accidents have increased significantly over the past decade. There were statistical differences in severity based on EMR-ISS and the hospitalization in intensive care unit and death.

Purpose

The optic nerve sheath diameter (ONSD) measured by ultrasonography is among the indicators of intracranial pressure (ICP) elevation. However, whether ONSD measurement is useful for initial treatment remains controversial. Thus, this study aimed to investigate the relationship between ONSD measured by computed tomography (CT) and ICP in patients with traumatic brain injury (TBI).

Methods

A total of 246 patients with severe trauma from January 1, 2015 until December 31, 2015 were included in the study. A total of 179 patients with brain damage with potential for ICP elevation were included in the TBI group. The remaining 67 patients comprised the non-TBI group. A comparison was made between the two groups. Receiver operating characteristic (ROC) curve analysis was performed to determine the accuracy of ONSD when used as a screening test for the TBI group including those with TBI with midline shift (with elevated ICP).

Results

The mean injury severity score (ISS) and glasgow coma scale (GCS) of all patients were 24.2±6.1 and 5.4±0.8, respectively. The mean ONSD of the TBI group (5.5±1.0 mm) was higher than that of the non-TBI group (4.7±0.6 mm). Some significant differences in age (55.3±18.1 vs. 49.0±14.8, p<0.001), GCS (11.7±4.1 versus 13.3±3.0, p<0.001), and ONSD (5.5±1.0 vs. 4.7±0.6, p<0.001) were observed between the TBI and the non-TBI group. An ROC analysis was used to assess the correlation between TBI and ONSD. Results showed an area under the ROC curve (AUC) value of 0.752. The same analysis was used in the TBI with midline shift group, which showed an AUC of 0.912.

Conclusions

An ONSD of >5.5 mm, measured on CT, is a good indicator of ICP elevation. However, since an ONSD is not sensitive enough to detect an increased ICP, it should only be used as one of the parameters in detecting ICP along with other screening tests.
