Huang W, Lin Q, Xu F, Chen D. Effect of COVID-19 on epidemiological characteristics of road traffic injuries in Suzhou: a retrospective study. BMC Emerg Med 2021; 21:88. [PMID: 34311702 PMCID: PMC8312208 DOI: 10.1186/s12873-021-00483-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Accepted: 07/19/2021] [Indexed: 01/16/2023] Open
Abstract
BACKGROUND To present the new trends in epidemiology of road traffic injuries (RTIs) during the Coronavirus disease 2019 (COVID-19) pandemic in Suzhou. METHODS Pre-hospital records of RTIs from January to May in 2020 and the same period in 2019 were obtained from the database of Suzhou pre-hospital emergency center, Jiangsu, China. Data were extracted for analysis, including demographic characteristics, pre-hospital vital signs, transport, shock index, consciousness, pre-hospital death. A retrospective study comparing epidemiological characteristics of RTIs in Suzhou during the 5-month period in 2020 to the parallel period in 2019 was performed. RESULTS A total of 7288 RTIs in 2020 and 8869 in 2019 met inclusion criteria. The overall volume of RTIs has statistical difference between the 2 years (p < 0.001), with fewer RTIs in 2020 compared with 2019. Electric bicycle related RTIs increased during the pandemic (2641, 36.24% vs 2380, 26.84%, p < 0.001), with a higher incidence of RTIs with disorder of consciousness (DOC) (7.22% vs 6.13%, p = 0.006). CONCLUSIONS Under the impact of COVID-19, the total number of RTIs in Suzhou from January to May 2020 decreased. This observation was coupled with a rise in electric bicycle related injuries and an increase in the incidence of RTIs with DOC.

[PMID: 32090972 DOI: 10.1016/j.jflm.2020.101917] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Revised: 11/22/2019] [Accepted: 01/26/2020] [Indexed: 11/16/2022]
Abstract
To understand the injury severity of bicyclists and motorcyclists in single vehicle collisions, we performed a retrospective analysis of forensic autopsy cases of 25 motorcyclists and 14 bicyclists performed from 1999 to 2018. Collision details, injury characteristics, and involvement of alcohol were examined. The injury severity between bicyclists and motorcyclists was compared. The average age of victims was 62.3 years. All motorcyclists and no bicyclists wore a helmet. Motorcyclists had more severe injuries than bicyclists (mean Injury Severity Score of 42 and 27, respectively). The motorcyclists had more severe chest injuries but fewer severe facial injuries than bicyclists, owing to the difference in collision velocity or rate of helmet use (p < 0.05). Alcohol was present in the blood of 52.0% of bicyclists but no motorcyclists. The mean blood alcohol concentration of these bicyclists was 1.59 mg/mL. The bicyclists under the influence of alcohol had more severe injuries to neck and upper extremities than non-drunken bicyclists (p < 0.05). Our results may be useful for determining the cause of death and reconstructing the mechanisms of fatal injuries in bicyclists and motorcyclists.

Abstract
Background Rising fuel cost and subsequent increase in transportation prices encourage people to use cheap transportation such as a bicycle. This vehicle can also be used for sports and recreation. Bicycles are widely used in Iran, like other countries. There is not enough data about bicycle-related traumas in our country. Objectives The aim of this study was to obtain the epidemiology of this type of injury in Tabriz Imam Reza Hospital as a referral center in northwest of Iran during 2009 to 2012. Materials and Methods One hundred bicycle-related patients during the three years were entered in this descriptive cross-sectional study. Patient’s demographics, place and time of crash, mechanism of trauma, helmet and other safety device usage, and disposition information were gathered by a researcher-made checklist. Admission rate and ward as well as the site of injuries were also collected. The data were analyzed by SPSS 16 software using descriptive statistics. Results All the patients were males with a mean age of 31.3 ± 23.12. Seventy six bicycle-related injuries occurred during weekdays and 24 happened on holidays; 71 patients attended the emergency department in the morning and 29 at night. Only three of 100 cyclists had helmets during the accident. The rates of injuries were as follows: 65 head and face, 20 abdomen, 14 chest, 11 soft tissue, eight lower limb, eight cervical spine, six upper limb, four thoracic and lumbar spine, and three pelvis injuries. Conclusions Head and face are the most common sites of injury and skull fracture is the most common one. Considering the preventable entity of trauma, the use of helmets seems to be beneficial to prevent most bicycle-related injuries.

Leg Med (Tokyo) 2016; 18:58-61. [PMID: 26832378 DOI: 10.1016/j.legalmed.2015.12.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2015] [Revised: 10/20/2015] [Accepted: 12/01/2015] [Indexed: 11/25/2022]
Abstract
The objective of this study was to clarify the relationship between injury severity and mechanism of death in bicycle fatalities resulting from trauma compared with those resulting from disease, to propose effective measures to prevent fatal bicyclist accidents. Autopsy and accident records were reviewed for bicyclist fatalities who had undergone forensic autopsy at the Dokkyo Medical University School of Medicine between September 1999 and March 2014. Victims' health histories, blood alcohol levels, causes of death, mechanisms of injury, Abbreviated Injury Scale (AIS) scores and Injury Severity Scores (ISSs) were determined. Fifty-five bicyclists (43 male and 12 female) with a mean age of 62.5±17.3 years were included in this study. Sixteen victims had driven under the influence of alcohol (mean blood concentration of 1.8±0.7 mg/ml). Mean ISS was 32.4 and the chest had the highest mean AIS score (2.6), followed by the head (2.1) and the neck (1.8). Thirty-nine victims (70.9%) had died of trauma and 16 had died of disease. The disease-death victims had significantly higher prevalence of having diabetes mellitus, hyperlipidemia, hypertension, heart disease or cerebrovascular diseases (50.0% vs. 22.2%, p=0.03) and a lower rate of drunk driving (6.3% vs. 41.0%, p=0.01) than the trauma-death group. All victims who were affected by disease, and 33.3% of trauma-death victims, had fallen on the road without a vehicle collision (p<0.001). The mean ISS of the trauma-death group was significantly higher than that of the disease-death group (44.0 vs. 4.2, p<0.001). Except for facial injuries, the AIS scores were significantly higher in trauma-death victims than in the disease-death group (p<0.005). To effectively reduce bicyclist fatalities, the authors strongly advocate efforts that will increase compliance with drunk driving prohibitions. For victims of fatal bicycle accidents with a medical history of diseases, a forensic autopsy should be performed to establish a disease-related death while bicycle riding. We must also put into effect preventative safety measures, which take into consideration the physical condition of bicyclists, to reduce the incidence of these types of accidents.

[PMID: 26219341 PMCID: PMC4517401 DOI: 10.1186/s12889-015-2075-9] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2015] [Accepted: 07/20/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND This study aimed to investigate differences in injury severity and mortality between patients who met with bicycle or motorcycle accidents and were hospitalized at a Level I trauma center in Taiwan. METHODS We performed a retrospective analysis of bicycle-related injuries that have been reported in the Trauma Registry System in order to identify and compare 699 bicyclists to 7,300 motorcyclists who were hospitalized for treatment between January 1, 2009 and December 31, 2013. Statistical analyses of the injury severity, associated complications, and length of stay in the hospital and intensive care unit (ICU) were performed to compare the risk of injury of bicyclists to that of motorcyclists with the corresponding unadjusted odds ratios and 95 % confidence intervals (CIs). Adjusted odds ratios (AORs) and 95 % CIs for mortality were calculated by controlling for confounding variables that included age, and an Injury Severity Score (ISS) was calculated. RESULTS More of the cyclists were under 19 years of age or over 70 than were the motorcyclists. In contrast, fewer bicyclists than motorcyclists wore helmets, arrived at the emergency department between 11 p.m. and 7 a.m., and had a positive blood alcohol concentration test. The bicyclists sustained significantly higher rates of injuries to the extremities, while motorcyclists sustained significantly higher rates of injuries to the head and neck, face, and thorax. Compared to motorcyclists, the bicyclists had significantly lower ISSs and New Injury Severity Scores, shorter length hospital stays, and a smaller proportion of admittance into the ICU. However, the bicyclists had higher AORs for in-hospital mortality (AOR: 1.2, 95 % CI: 1.16-1.20). In terms of critical injury severity (ISS ≥ 25), the bicyclists had 4.4 times (95 % CI: 1.95-9.82) the odds of mortality than motorcyclists with the same ISSs. CONCLUSIONS Data analysis indicated that the bicyclists had unique injury characteristics including bodily injury patterns and lower ISSs, but had higher in-hospital mortality compared to motorcycle riders. In this study, given that only 9 % of bicyclists reported wearing helmets and considering the high mortality associated with head injury, it is possible that some bicycle riders underestimated the gravity of cycling accidents.
