RESUMO
BACKGROUND: Race and insurance status have been shown to predict outcomes in pediatric bicycle traumas. It is unknown how these factors influence outcomes in adult bicycle traumas. This study aims to evaluate the association, if any, between race and insurance status with mortality in adults. METHODS: This retrospective cohort study used the National Trauma Data Bank Research Data Set for the years 2013-2015. Multivariate logistic regression models were used to determine the independent association between patient race and insurance status on helmet use and on outcomes after hospitalization for bicycle-related injury. These models adjusted for demographic factors and comorbid variables. When examining the association between race and insurance status with outcomes after hospitalization, injury characteristics were also included. RESULTS: A study population of 45,063 met the inclusion and exclusion criteria. Multivariate regression demonstrated that black adults and Hispanic adults were significantly less likely to be helmeted at the time of injury than white adults [adjusted odds ratio of helmet use for blacks 0.25 (95% CI 0.22-0.28) and for Hispanics 0.33 (95% CI 0.30-0.36) versus whites]. Helmet usage was also independently associated with insurance status, with Medicare-insured patients [AOR 0.51 (95% CI 0.47-0.56) versus private-insured patients], Medicaid-insured patients [AOR 0.18 (95% CI 0.17-0.20)], and uninsured patients [AOR 0.29 (95% CI 0.27-0.32)] being significantly less likely to be wearing a helmet at the time of injury compared with private-insured patients. Although patient race was not independently associated with hospital mortality among adult bicyclists, we found that uninsured patients had significantly higher odds of mortality [AOR 2.02 (AOR 1.31-3.12)] compared with private-insured patients. CONCLUSIONS: Minorities and underinsured patients are significantly less likely to be helmeted at the time of bicycle-related trauma when compared with white patients and those with private insurance. Public health efforts to improve the utilization of helmets during bicycling should target these subpopulations.

Objectives: Increasing bicycle ridership is accompanied by ongoing bicycle-related accidents in many urban cities. There is a need for improved understanding of patterns and risks of urban bicycle usage. We describe the injuries and outcomes of bicycle-related trauma in Boston, Massachusetts, and determine accident-related factors and behaviors associated with injury severity. Methods: We conducted a retrospective review via chart review of 313 bicycle-related injuries presenting to a Level 1 trauma center in Boston, Massachusetts. These patients were also surveyed regarding accident-related factors, personal safety practices, and road and environmental conditions during the accident. Results: Over half of all cyclists biked for commuting and recreational purposes (54%), used a road without a bike lane (58%), and a majority wore a helmet (91%). The most common injury pattern involved the extremities (42%) followed by head injuries (13%). Bicycling for commuting rather than recreation, cycling on a road with a dedicated bicycle lane, the absence of gravel or sand, and use of bicycle lights were all factors associated with decreased injury severity (p<0.05). After any bicycle injury, the number of miles cycled decreased significantly regardless of cycling purpose. Conclusion: Our results suggest that physical separation of cyclists from motor vehicles via bicycle lanes, regular cleaning of these lanes, and usage of bicycle lights are modifiable factors protective against injury and injury severity. Safe bicycling practices and understanding of factors involved in bicycle-related trauma can reduce injury severity and guide effective public health initiatives and urban planning.
RESUMO
PURPOSE: Chronic opioid use is a significant public health burden. Orthopaedic trauma is one of the main indications for opioid prescription. We aimed to assess the risk for long-term opioid use in a healthy patient cohort. METHODS: In this matched cohort study, bicycle trauma patients from a Swedish Level-I-Trauma Centre in 2006-2015 were matched with comparators on age, sex, and municipality. Information about dispensed opioids 6 months prior until 18 months following the trauma, data on injuries, comorbidity, and socioeconomic factors were received from national registers. Among bicycle trauma patients, the associations between two exposures (educational level and injury to the lower extremities) and the risk of long-term opioid use (> 3 months after the trauma) were assessed in multivariable logistic regression models. RESULTS: Of 907 bicycle trauma patients, 419 (46%) received opioid prescriptions, whereof 74 (8%) became long-term users. In the first quarter after trauma, the mean opioid use was significantly higher in the trauma patients than in the comparators (253.2 mg vs 35.1 mg, p < 0.001) and fell thereafter to the same level as in the comparators. Severe injury to the lower extremities was associated with an increased risk of long-term opioid use [OR 4.88 (95% CI 2.34-10.15)], whereas high educational level had a protecting effect [OR 0.42 (95% CI 0.20-0.88)]. CONCLUSION: The risk of long-term opioid use after a bicycle trauma was low. However, opioids should be prescribed with caution, especially in those with injury to lower extremities or low educational level.

Purpose: Electric bicycles (e-bikes) achieve higher speeds than pedal bicycles, but few studies have investigated the impact on injury rates specific to the pediatric population. Utilizing the National Electronic Injury Surveillance System (NEISS), we compared rates of pediatric injury for e-bikes, bicycles, and gas-engine bicycles (mopeds) from 2011 to 2020. Methods: Descriptive and bivariate inferential analyses were performed upon NEISS estimates of e-bike, bicycle, and moped injuries in children aged 2-18 years. Analyses were stratified by patient age and helmet usage. The Mann-Kendall test of trends was used. Results: We identified 3945 e-bike, 23,389 moped, and 2.05 million bicycle injuries. Over time, the incidence of injury increased for e-bikes (Kendall's τ=0.73, p = 0.004), decreased for pedal bicycles (Kendall's τ= - 0.91, p = 0.0003), and did not change for mopeds (Kendall's τ = 0.06, p = 0.85). Males accounted for 82.5 % of e-bike injuries. The age group most commonly affected by e-bike injury (44.3 %) was 10-13 years old. The proportion of injuries requiring hospitalization was significantly higher for e-bikes (11.5 %), compared to moped and bicycle (7.0 and 4.8 %, respectively, p < 0.0001). In cases where helmet use or absence was reported, 97.3 % of e-bike riders were without a helmet at the time of injury, compared to 82.1 % of pedal bicycle riders and 87.2 % of moped riders. Conclusions: The rate of pediatric e-bike injuries increased over the study period. Compared to riders on pedal bicycles or mopeds, children on e-bikes had infrequent helmet use and increased rate of hospitalization. These findings suggest that attention to e-bike safety and increasing helmet usage are important to public health among the pediatric population. Level of evidence: IV.
RESUMO
BACKGROUND: In Western Australia, the media has reported on an increase in the purchasing, repairs and use of bicycles during the COVID-19 period. The study aimed to investigate for a relationship in bicycle related injuries in the paediatric population during the time of COVID-19 restrictions. METHODS: A retrospective study of the incident of motorized and non-motorized bicycle related injuries and trauma presentations during the COVID-19 'shutdown' period from March to June 2020. Data were collected from the Emergency Department Information System, discharge summaries, operation and radiology reports. The data presented is from Perth Children's Hospital, the only tertiary paediatric hospital and the only referral centre for childhood trauma in the state of Western Australia. Participants were children aged 15 years and younger attending the emergency department (ED) at Perth Children's Hospital during the designated time period. The primary outcomes included total ED presentations, bicycle related presentations and bicycle related admissions during the COVID-19 period. RESULTS: Bicycle related presentations to the ED increased by 42.7% over the COVID-19 period from 1.4% to 3.0% of all children attending the ED. Children admitted to the hospital with bicycle related injuries or trauma increased by 48.7% from 76 to 113 children in comparison to the same period in 2019. CONCLUSION: During the period of COVID-19 restrictions, paediatric ED presentations decreased dramatically, but bicycle related injuries and trauma increased substantially. Safety equipment including helmets and protective gear should be worn for all children riding bicycles, and social distancing should be maintained.

BACKGROUND: This study aimed to characterize bodily injury patterns associated with helmet usage by comparing trauma sustained by helmeted and helmetless cyclists admitted to a large US health-care system. MATERIALS AND METHODS: A prospective trauma registry associated with a large regional United States health-care network was queried for bicycle injuries resulting in hospital admission over a 5-year period. Data pertaining to helmet usage, demographics, injury description (s), Abbreviated Injury Scale score, Injury Severity Score, and hospital length of stay were collected from 140 patients treated for bicycle-related injuries. Mann-Whitney tests were performed. RESULTS: Fifty-six of the injured cyclists were helmeted (40%) and 84 were not helmeted (60%). A significantly greater proportion of helmeted cyclists exhibited abrasions and a higher incidence of injury across all injury types (P = <0.001 and 0.003). The number and severity of injury to the external body (P = <0.001 and 0.001) and overall injury severity (P = 0.004) for patients with multiple injuries were also significantly greater among helmeted cyclists. Helmeted cyclists did demonstrate significantly shorter hospital stays (P = 0.021). CONCLUSION: While the helmeted and helmetless riders admitted to the emergency department exhibit few differences in injury patterns, when significant injury differences were detected, they were more prevalent in helmeted riders. These differences were represented by minor-to-moderate injuries relative to morbidity and mortality, suggesting that the trauma profile of the helmeted and helmetless riders is relatively comparable. Yet, helmetless wearers did have significantly longer hospital stays, which may indicate underlying health disparities and/or behavioral differences.
RESUMO
BACKGROUND: Epidemiological studies have shown that bicycle trauma is associated with genitourinary (GU) injuries. Our objective is to characterize GU-related bicycle trauma admitted to a level I trauma center. MATERIALS AND METHODS: We queried a prospective trauma registry for bicycle injuries over a 20-year period. Patient demographics, triage data, operative interventions and hospital details were collected. RESULTS: In total, 1659 patients were admitted with major bicycle trauma. Of these, 48 cases involved a GU organ, specifically the bladder (n=7), testis (n=6), urethra (n=3), adrenal (n=4) and/or kidneys (n=36). The median age of cyclists with GU injuries was 29 (range 5-70). More men were injured versus women (35 versus 13). GU-related bicycle trauma involved a motor vehicle in 52% (25/48) of injuries. The median injury severity score for GU-related bicycle trauma was 17 (range 1-50). The median number of concomitant organ injuries was 2 (range 0-6), the most common of which was the lungs (13/48, 27%) and ribs (13/48, 27%). The majority of GU injured cyclists were admitted to an ICU (15/48, 31%) or hospital floor (12/48, 25%). Operative intervention for a GU-related trauma was low (12/48, 25%). The most common GU organ injured was the kidney (36/48, 75%) however most were managed nonoperatively (33/36, 92%). Bladder injuries most often required operative intervention (6/7, 86%). Mortality following GU-related bicycle trauma was low (2/48, 4%). CONCLUSIONS: In a large series of bicycle trauma, GU organs were injured in 3% of cases. The majority of cases were managed non-operatively and mortality was low.

Alcohol use is a risk factor for severe injury in pedestrians struck by motor vehicles. Our objective was to investigate alcohol use by bicyclists and its effects on riding behaviors, medical management, injury severity, and mortality within a congested urban setting. A hospital-based, observational study of injured bicyclists presenting to a Level I regional trauma center in New York City was conducted. Data were collected prospectively from 2012 to 2014 by interviewing all bicyclists presenting within 24 h of injury and supplemented with medical record review. Variables included demographic characteristics, scene-related data, Glasgow Coma Scale (GCS), computed tomography (CT) scans, and clinical outcomes. Alcohol use at the time of injury was determined by history or blood alcohol level (BAL) >0.01 g/dL. Of 689 bicyclists, 585 (84.9%) were male with a mean age of 35.2. One hundred four (15.1%) bicyclists had consumed alcohol prior to injury. Alcohol use was inversely associated with helmet use (16.5% [9.9-25.1] vs. 43.2% [39.1-47.3]). Alcohol-consuming bicyclists were more likely to fall from their bicycles (42.0% [32.2-52.3] vs. 24.2% [20.8-27.9]) and less likely to be injured by collision with a motor vehicle (52.0% [41.7-62.1] vs. 67.5% [63.5-71.3]). 80% of alcohol-consuming bicyclists underwent CT imaging at presentation compared with 51.5% of non-users. Mortality was higher among injured bicyclists who had used alcohol (2.9% [0.6-8.2] vs. 0.0% [0.0-0.6]). Adjusted multivariable analysis revealed that alcohol use was independently associated with more severe injury (Adjusted Odds Ratio 2.27, p = 0.001, 95% Confidence Interval 1.40-3.68). Within a dense urban environment, alcohol use by bicyclists was associated with more severe injury, greater hospital resource use, and higher mortality. As bicycling continues to increase in popularity internationally, it is important to heighten awareness about the risks and consequences of bicycling while under the influence of alcohol.

INTRODUCTION: Bicycle crashes often affect individuals in working age, and can impair quality of life (QoL) as a consequence. The aim of this study was to investigate QoL in bicycle trauma patients and to identify those at risk of impaired QoL. PATIENTS AND METHODS: 173 bicycle trauma patients who attended a level I trauma centre from 2010 to 2012 received Hadorn's QoL questionnaire six months after their crash. Medical data was collected from the patient's records. Univariate ordinal logistic regression was used to investigate the association between QoL and other factors. RESULTS: 148 patients returned the questionnaire (85.5%). The majority had only mild or minor injuries (85.1%; n=126). However, 72.1% (n=106) still suffered from pain or other physical symptoms more than six months after their bicycle crash. Patients with a Glasgow Coma Scale (GCS) ≤13 or an Injury Severity Score (ISS) >15 experienced impaired emotions/outlook on life (p-values 0.003 and 0.045, respectively). Physical suffering was reported by patients with a GCS ≤13 and in those with injuries to the cervical spine (p-values 0.02 and 0.025, respectively). Patients with an ISS >15 or facial fractures experienced limitations in daily activities (p-values 0.031 and 0.025, respectively). CONCLUSIONS: More than 70% of bicycle trauma patients suffered physically more than six months after their crash, even though only 15% were severely injured. Risk factors for an impaired QoL were cervical spine injuries or facial fractures, a GCS ≤13 and an ISS >15.

PURPOSE: Worldwide, the use of bicycles, for both recreation and commuting, is increasing. S100B, a suggested protein biomarker for cerebral injury, has been shown to correlate to extracranial injury as well. Using serum levels of S100B, we aimed to investigate how S100B could be used when assessing injuries in patients suffering from bicycle trauma injury. As a secondary aim, we investigated how hospital length of stay and injury severity score (ISS) were correlated to S100B levels. METHODS: We performed a retrospective, database study including all patients admitted for bicycle trauma to a level 1 trauma center over a four-year period with admission samples of S100B (n = 127). Computerized tomography (CT) scans were reviewed and remaining data were collected from case records. Univariate- and multivariate regression analyses, linear regressions and comparative statistics (Mann-Whitney) were used where appropriate. RESULTS: Both intra- and extracranial injuries were correlated with S100B levels. Stockholm CT score presented the best correlation of an intracranial parameter with S100B levels (p < 0.0001), while the presences of extremity injury, thoracic injury, and non-cervical spinal injury were also significantly correlated (all p < 0.0001, respectively). A multivariate linear regression revealed that Stockholm CT score, non-cervical spinal injury, and abdominal injury all independently correlated with levels of S100B. Patients with a ISS > 15 had higher S100 levels than patients with ISS < 16 (p < 0.0001). Patients with extracranial, as well as intracranial- and extracranial injuries, had significantly higher levels of S100B than patients without injuries (p < 0.05 and p < 0.01, respectively). The admission serum levels of S100B (log, µg/L) were correlated with ISS (log) (r = 0.53) and length of stay (log, days) (r = 0.45). CONCLUSIONS: S100B levels were independently correlated with intracranial pathology, but also with the extent of extracranial injury. Length of stay and ISS were both correlated with the admission levels of S100B in bicycle trauma, suggesting S100B to be a good marker of aggregated injury severity. Further studies are warranted to confirm our findings.

INTRODUCTION: In recent years, the increasing number of bicyclists has evoked the debate on use of bicycle helmet. The aim of this study was to investigate the association between helmet use and injury pattern in bicycle trauma patients. PATIENTS AND METHODS: We performed a retrospective population-based study of 186 patients treated for bicycle-related injuries at a Level 1 Trauma Centre in Sweden during a 3-year period. Data were collected from case records. Unconditional logistic regression was used to calculate odds ratios (ORs), and 95% confidence intervals (CIs). RESULTS: 43.5% of the 186 patients used a bicycle helmet at the time of the crash. Helmet users were less likely to get head and facial injuries in collisions than non-helmet users (OR, 0.3; 95% CI, 0.07-0.8, and OR, 0.07; 95% CI, 0.02-0.3), whereas no difference was seen in single-vehicle accidents. The risk of limb injuries was higher among helmet users. CONCLUSIONS: Non-helmet use is associated with an increased risk of injury to head and face in collisions, whereas helmet use is associated with an increased risk of limb injuries in all types of crashes.

INTRODUCTION: As bicycling has become more popular, admissions after bicycle trauma are on the rise. The impact of alcohol use on bicycle trauma has not been well studied. The aim of this study was to examine the effect of alcohol intoxication on injury burden following bicycle-related crashes. METHODS: A retrospective review of trauma patients presenting to a Level I trauma center after bicycle-related crashes from January 2002 to December 2011 was conducted. Demographics, injury data, alcohol intoxication, helmet use, and clinical outcomes were reviewed. Blood alcohol level (BAL) was considered positive if >0.01 g/dL. Variables were compared between patients based on BAL: negative, 0.01-0.16 g/dL, and >0.16 g/dL. RESULTS: During the 10 year study period, 563 patients met study criteria; mean age was 33.5 ± 16.5 years, 87% were male, and mortality was 1%. On average, bicycle crashes increased over the study period by 4.4 collisions per year. BAL was tested in 211 (38%) patients. Mean BAL was 0.24 g/dL, with 37% of these patients being intoxicated (BAL ≥ 0.010 g/dL). Intoxicated patients were significantly less likely to wear a helmet (4.7% vs. 22.2%, p = 0.002) and to be involved in motor vehicle crash (59.0% vs. 81.2%, p < 0.001). There was no difference noted in the injury burden including ISS ≥ 16 (14.3% vs. 19.5%, p = 0.335) and AIS Head ≥ 3 (17.9% vs. 21.8%, p = 0.502). When comparing patients according to their BAL, there was a decreasing risk of motor vehicle collision with increasing BAL (81.2% for undetected, 76.5% for BAL ≤ 0.16 g/dL and 54.1% for BAL >0.16 g/dL, p < 0.001). The risk for a severe head injury (AIS Head ≥ 3) was significantly lower in helmeted patients (8.4% vs. 15.8%, p = 0.035). CONCLUSIONS: The incidence of bicycle-related crashes is increasing and more than a third of patients tested for alcohol after bicycle-related crashes are found to be intoxicated. The injury burden in intoxicated patients, including head trauma, was not different compared to non-intoxicated patients. In addition, the risk for a collision with a motor vehicle was significantly lower. Nonetheless, these patients rarely utilize a helmet. The findings from this study can be used for the development and implementation of preventive strategies to minimize the injury burden associated with bicycle crashes and intoxicated cyclists.
