All terrain vehicles (ATVs). A recreational gamble

Over the period September 1985 to July 1986, the authors reviewed 28 admissions to the Level I trauma center as a result of all-terrain vehicle (ATV) accidents. The patients ranged in age from 6 to 71 years, with nearly 33 per cent (9), under age 16. There were 22 (78.6%) male and 6 (21.4%) female patients. All suffered multiple abrasions, lacerations, and contusions. In addition, 21 (75%) patients had a fracture of some type. Eight (28.6%), had head injuries and 3 (10.7%) sustained spinal cord injuries with a permanent neurologic deficit. Intrathoracic injury occurred in 2 patients (7.1%) and intraabdominal injuries occurred in 1 (3.6%). Moreover, death occurred in 3 (10.7%). Simultaneously reviewed were admissions resulting from motor vehicle accidents (MVA) and motorcycle accidents (MCA) during the same period. By comparison, the death rates (DR), fracture rates (FR), and spinal cord lesions with deficit (SLR) were significantly higher in accidents with ATVs than with MVAs or MCAs. The death rates for ATVs, MVAs, and MCAs were 10.7 per cent, 4.6 per cent, and 1.2 per cent, respectively, with significance between the MCA and ATV groups, P = .0395. The FR were 75 per cent, 53 per cent, and 65 per cent, respectively, with P = .265. SLR was found in 10.7 per cent, 2.3 per cent, and 4.4 per cent of these same groups, with P = .0001. These data suggest that ATV riders are at a higher risk for sustaining fractures, significant spinal cord injuries, or death. ATVs clearly present a health hazard to riders of all ages.     

All-terrain vehicle injuries: are they dangerous? A 6-year experience at a level I trauma center after legislative regulations expired

All-terrain vehicles (ATVs) have increased in popularity and sales since 1971. This rise in popularity led to an increase in injuries resulting in voluntary industry rider safety regulations in 1988, which expired without renewal in 1998. Our purpose was twofold, to determine the incidence and severity of ATV injuries in our patient population and what, if any impact the safety regulations had. To further characterize the risk of ATV use, we compared them to a vehicle generally recognized as dangerous, the motorcycle (MC). Our trauma registry was reviewed from January 1998 through August 2004 for ATV or MC injured. Data collected included age, gender, mortality, Injury Severity Score (ISS), helmet use, and injury distribution. These were compared to our data from the decade of regulation. There were 352 MC and 221 ATV patients. ATV injured demonstrated a higher proportion of pediatric and female patients (P < 0.001 and P < 0.01, respectively), a decrease in helmet use (8.6% vs 64.7%, P < 0.001), and increased closed head injuries (CHI) (54.2% vs 44.9%, P < 0.05) compared with MC injured. ISS and mortality were similar. The average number of patients from 1988 to 1998 was 6.9/yr compared to 31.6/yr (P < 0.001) during 1998-2004 with equal ISS. Our data show that there has been a dramatic and progressive increase in the number of ATV crashes since expiration of industry regulations. ATVs are as dangerous as MCs based on patient ISS and mortality. There are significantly more children and women injured on ATVs. The lower rate of helmet use in ATVs may account for the significantly greater incidence of CHI. These data mandate the need for injury prevention efforts for ATV riders, in particular children, through increased public awareness and new legislation.     

All-terrain vehicle and bicycle crashes in children: epidemiology and comparison of injury severity

Background/Purpose: Despite statements by the American Academy of Pediatrics (AAP) and the US Consumer Product Safety Commission (CPSC) against the use of all-terrain vehicles (ATVs) by children under the age of 16 years, nearly half of ATV-related injuries and over 35% of all ATV-related deaths continue to occur in this age group. Because ATV and bicycle crashes have been associated with serious injury in children, the authors compared the demographics, mechanism of injury, injury severity, and outcome of children with ATV- and bicycle-related injuries. Further, the authors sought to identify whether ATV-related injuries elicited changes in risk-taking behavior. Methods: A retrospective, comparative analysis of 109 children admitted for ATV-related injuries and 994 children admitted for bicycle-related injuries to a level 1 pediatric trauma center between January 1991 and June 2000 was performed. A phone survey was conducted to determine self-reported changes in safety behaviors or use patterns after ATV injury. Results: Mean age was 11.1 [plusmn] 3.5 years (range, 2 to 18 years) for ATV crashes versus 9.4 [plusmn] 3.3 years (range, 1 to 17 years) for bicycle crashes (P [lt ] .05). Ninety-three percent of ATV crashes occurred in children less than 16 years of age; 31% in children [le ]10 years of age; and 7% in children [le ]5 years of age. Male-to-female ratio was about 3:1 for both groups. White race accounted for 97% of ATV injuries compared with 79% of bicycle injuries (P [lt ] .05). Falls from ATVs or bicycles were the most common mechanism of injury (41% v 59%, respectively). Collisions with motor vehicles were more common for bicyclists (32% v 10%), whereas collisions with stationary objects were more common among ATV riders (27% v 9%). Sixteen percent of ATV crashes were caused by a roll-over mechanism. Mean injury severity score (ISS) were significantly higher for victims of ATV crashes (8.3 ATV v 6.7 bicycle; P [lt ] .05). ATV-related trauma was associated with multiple injuries, more operative interventions, and longer hospital stays. Location and distribution of injuries were similar for both groups. Helmet use was low in both groups but higher for ATV riders (23% v 8%; P [lt ] .5). Mortality rate was similar for both groups (0.9% for ATV riders v 0.7% for bicyclists). There was a 39% response for the phone survey post-ATV injury. Twenty-three of 43 (53%) respondents owned the ATV, and 70% of these received safety information at the time of purchase. However, only 14% of injured riders received any formal training before riding ATVs. Postinjury, 60% of children continued to ride, although 42% reported decreased riding time. Fifty-four percent of children reportedly wore helmets preinjury, and there were no changes in helmet usage postinjury. There were no differences in pre- and postinjury parental supervision (61% v 65%). Conclusions: Both ATV and bicycle-related injuries occur predominantly in boys, but ATV victims are older and almost all are white. Almost all ATV injuries occurred in children under the age of 16 years. Although both ATV and bicycle crashes cause severe injuries in children, injury severity is higher for ATV crashes in terms of multiple injuries, need for operative intervention, and longer length of stay. Despite severe injuries, the majority of children injured by ATVs continue to ride, albeit fewer hours per day, and safety behaviors are unaltered. These data reinforce the current AAP stance that legislation prohibiting the use of ATVs in children under the age of 16 years without a valid driver's license should be pursued and enforced aggressively.     

Perils of rib fractures

Rib fractures (RF) are noted in 4 to 12 per cent of trauma admissions. To define RF risks at a Level 1 trauma center, investigators conducted a 10-year (1995-2004) retrospective analysis of all trauma patients. Blunt chest trauma was seen in 13 per cent (1,475/11,533) of patients and RF in 808 patients (55% blunt chest trauma, 7% blunt trauma). RF were observed in 26 per cent of children (< 18 years), 56 per cent of adults (18-64 years), and 65 per cent of elderly patients (> or = 65 years). RF were caused by motorcycle crashes (16%, 57/347), motor vehicle crashes (12%, 411/3493), pedestrian-auto collisions (8%, 31/404), and falls (5%, 227/5018). Mortality was 12 per cent (97/808; children 17%, 8/46; adults 9%, 46/522; elderly 18%, 43/240) and was linearly associated with a higher number of RF (5% 1-2 RF, 15% 3-5 RF, 34% > or = 6 RF). Elderly patients had the highest mortality in each RF category. Patients with an injury severity score > or = 15 had 20 per cent mortality versus 2.7 per cent with ISS < 15 (P < 0.0001). Increasing age and number of RF were inversely related to the percentage of patients discharged home. ISS, age, number of RF, and injury mechanism determine patients' course and outcome. Patients with associated injuries, extremes of age, and > or = 3 RF should be admitted for close observation.     

Unsafe at any age: a retrospective review of all-terrain vehicle injuries in two level I trauma centers from 1995 to 2003

BACKGROUND: All-terrain vehicles (ATVs) are popular recreational and utility vehicles. In 1984, Cogbill published an article regarding three-wheelers. These are no longer manufactured, but the injury and death rate with four-wheeled ATVs is high and disproportionately affects young riders. METHODS: We conducted a retrospective review at two Level I trauma centers from January 1994 to April 2003. Statistical analysis was performed using the SAS V8.2 program. Values of p < 0.05 were significant. RESULTS: Two hundred eight patients were identified. There were no differences identified in demographics, mechanism, types of injury, Injury Severity Score (ISS), or Glasgow Coma Scale (GCS) score. Seventy-five percent were male and 84% were white. The mean age was 23 +/- 13 years. The average ISS was 12.3 +/- 9 and the mean GCS score was 13.1 +/- 3.7. Injury mechanisms were loss of stability (33%), separation of rider from ATV (32%), and ATV versus stationary object (27%). ISS for ages 12 to 15 years was significantly higher than for other ages (14.5 vs. 11.5, p = 0.04, Wilcoxon rank sum test) and included more major head injuries (40.4% vs. 21.8%, p = 0.09, Wilcoxon rank sum test). They experienced fewer spinal fractures (3.9% vs. 15.4%, p = 0.03) and pelvic injuries (0% vs. 9%, p = 0.02, Wilcoxon rank sum test). The GCS score in this group was lower (12.3 vs. 13.4, p = 0.03, Wilcoxon rank sum test). CONCLUSION: Adolescent ATV riders have more severe injuries and more head injuries than other age groups. Prevention efforts should target this group.     

All-terrain vehicle injuries. A review at a rural level II trauma center

All-terrain vehicles (ATVs) have become a major source of morbidity and mortality with more than 600 deaths nationwide. Nearly half of those injured are children under 16 years. Twenty three ATV accidents were seen at the Guthrie Medical Center over a 30 month period ending in August 1986. Ten patients (43.5%) were under 16 years old. Of those injured who were older, alcohol was involved in 70 per cent of the accidents. Five accidents occurred on highways (21.7%), in spite of laws banning their use on public roads. Rollover type accidents and collisions were the most frequent mechanisms of injury (39% and 35%). Of 18 patients known not to have worn a helmet, 61 per cent sustained a closed head injury. In all, there were 88 injuries in 23 patients. Common injuries included lacerations (13), long bone fractures (13), renal contusions (11) and head injury (11). There were two deaths (8.7%), two cord transections with permanent disability, and a below-knee amputation. ATVs present a serious hazard to adult and children riders alike. Age limits, state licensing, safety programs, and protective equipment are all recommended as a means to reduce injury and death from recreational riding.     

Motorcycle injuries at a tertiary referral hospital in Kenya: injury patterns and outcome

Background

The rise in the use of motorcycles in Kenya in the last 10 years has been associated with increased injury rates. Between 2004 and 2009, motorcycle injuries increased at a rate of 29 % and, in some hospitals, motorcycle users have become the predominant road user category injured. Although most road traffic injuries occur in Nairobi, there has been no previous account of motorcycle injury and associated outcomes at its main hospital.

Objective

To describe the injury patterns and outcomes following motorcycle trauma at the Kenyatta National Hospital.

Methods

All motorcycle trauma admissions during one calendar year were analyzed. The data captured included demographics, injury patterns and outcomes, lengths of hospital stay, hospitalization cost, and early hospital mortality. Factors associated with outcomes were analyzed by univariate and multivariate means. The probability of survival was estimated using the Trauma and Injury Severity Score (TRISS) methodology for each patient.

Results

Two hundred and five patients were reviewed. Motorcycle trauma admissions formed 22.3 % of all road traffic injury admissions. Male riders predominated. The average age and modal age group was 30.78 and 21–30 years, respectively. Half of riders and 20 % of passengers used protective helmets. Injuries were mostly to the extremities (60.7 %) and head/neck (32.07 %), and the average Injury Severity Score (ISS) was 7.57 + 4.0 (median 9.0). At 2 weeks, 9.0 % of patients had died. The estimated probability of survival ranged from 0.86 to 0.97. Surgical interventions were needed for 51.7 % of patients. The mean length of stay in the hospital was 24.3 days, while the cost of treatment was 31,783 Kenya Shillings (Kshs). Injury severity (P < 0.001), admission to the intensive care unit (ICU) (P < 0.001), non-surgical treatment (P = 0.003), blood transfusion (P = 0.029), head injury (P < 0.001), and low Glasgow Coma Scale (GCS) score at admission were significantly associated with mortality.

Conclusion

Injuries to the lower limbs and the head predominate in motorcycle trauma. The high mortality rate, need for surgery in the majority of patients, and prolonged admission days call for motorcycle control and expedited care. Significant head injury mortality calls for efforts to embrace helmet laws for riders and passengers.     

Trauma in nonagenarians and centenarians: review of 137 consecutive patients

The purpose of this study was to examine the hospital course and outcomes of elderly trauma patients. We accomplished a retrospective review of all consecutive trauma patients admitted to a level II trauma center from January 2000 to April 2002. Gender, Injury Severity Score (ISS), length of stay (LOS), operative procedure, morbidity, and mortality of patients > or = 90 years of age were compared with younger patients. Of 2645 trauma admissions, 137 patients (5%) were > or = 90 years (range, 90 to 108 years; mean, 93.1 years); 5 patients were > or = 100 years. One hundred eleven (81%) patients were female; 26 (19%) male. Average ISS for patients > or = 90 was 8.75 and was 7.78 for younger patients. One hundred sixteen elderly patients (85%) had ISS < 15. Falls were the most common mechanism of injury (93%), usually ground-level falls (64%). Two hundred ninety-two injuries included 133 fractures and 102 soft tissue injuries. Thirty-four elderly patients (25%) and 733 younger patients (29%) required surgery. Complications developed in 8 per cent of older and 6 per cent of younger patients. Hospital LOS averaged 4.36 days for older and 3.51 days for younger patients. Six older (4.4%) and 63 younger (2.5%) patients died. ISS scores and LOS were slightly higher in elderly patients, but morbidity and mortality were comparable in both groups.     

Association of age and severe injury in young motorcycle riders: A cross-sectional study from Karachi,Pakistan

IntroductionThe burden imposed by motorcyclist deaths and injuries is high in low- and middle-income countries. Many injured motorcycle riders in these settings are underage. The aim of this study was to assess the association between age and severe injury in young motorcycle riders.MethodsWe analysed road traffic injury surveillance data from the emergency rooms of five hospitals in Karachi from 2007 to 2015. We used logistic regression to assess the association of motorcycle riders’ age, categorised as underage (13-17 years), early licensing age (18-19 years) and late licensing age (20-24 years), with severe injury, defined as an Injury Severity Score (ISS) ≥ 16.ResultsThe study sample included 45,366 motorcycle riders. There were 10115 (22.3%) motorcycle riders aged 13-17 years, 9899 (21.8%) aged 18-19 years and 25352 (55.9%) aged 20-24 years. Almost all were male (99%). Being aged 13-17 years (adjusted odds ratio 1.25; 95% CI 1.11, 1.42) and 18-19 years (adjusted odds ratio 1.26; 95% CI 1.10, 1.43) were associated with higher odds of severe injury compared with being aged 20-24 years.ConclusionMotorcycle riders who presented to the hospital with injuries after road traffic crashes and were aged 13-17 years and 18-19 years had significantly higher odds of severe injury than those aged 20-24 years.     

All-terrain vehicle injuries in children: industry-regulated failure.

Although the sale of all-terrain vehicles (ATVs) to children under 16 years of age was prohibited in 1988, they continue to represent half of the ATV-associated injuries. We conducted a retrospective review of ATV injuries admitted to our institution from 1988 to 1998. We identified 76 patients over the last 10 years, with 50 patients admitted in the last 4 years. Children <16 years of age account for 50 per cent of all ATV-injured patients. Only eight per cent of these children wore helmets. We conclude that despite industry regulation, nearly half of ATV injuries continue to involve children under 16 years of age. The consent decree restricting access of children <16 years of age to ATVs has been ineffective and expired in April 1998. Significant morbidity and mortality continues to occur in children <16 years of age who operate these vehicles. Reform is needed, such as legislation that would mandate the sale of safety equipment on ATV purchase, as well as provide for ATV safety education.     

Survey of factors influencing injury among riders involved in motorized two-wheeler accidents in India: a prospective study of 302 cases

Two-wheeler trauma in developing countries differs in some respects when compared to that in developed countries. A total of 302 cases involved in motorcycle, scooter, and moped accidents were analyzed. There were 201 drivers and 101 passengers. Injury severity scores (ISS), overall number of wounds, and number of fractures were studied. Motorcycle riders had a significantly higher ISS than did scooter riders. Persons involved in collisions with other powered vehicles had 36% more fractures and higher ISS than those involved in accidents where no collision occurred with a powered vehicle. Female passengers, sitting sideways, and involved in collisions, sustained fewer injuries than did a comparable group of male passengers who sat astride; the ISS of female passengers was also lower. Helmet users had a much lower incidence and severity of head injury than riders who did not use helmets. Turbans appeared to offer partial protection from head injury.     

Statewide assessment of injury and death rates among riders of off-road vehicles treated at trauma centers

BACKGROUND: Injuries and deaths among riders of off-road motorized all-terrain vehicles are increasing in the US. We hypothesized that serious injuries in Oregon have increased among riders of both four-wheel and two-wheel vehicles. STUDY DESIGN: We analyzed the Oregon Trauma Registry. Seriously injured patients treated in the state's designated urban and rural trauma centers were identified using E-codes (821.0 to 821.9), which indicate whether patients were riding either an off-road all-terrain four-wheel vehicle (ATV) or off-road two-wheeled motorcycle (ORMC). Second, we performed a supplemental analysis of similar patients in the trauma registry of Oregon's University-based tertiary care trauma center. Patients in earlier time periods were compared with those in later time periods. RESULTS: Patients injured riding off-road vehicles and needing treatment in Oregon's trauma centers increased 76%. Sixty percent of patients were injured riding an ATV, and 35% were injured riding an ORMC. Children (aged younger than 15 years) were 20% and 23% of patients in the earlier and later years. At Oregon's University-based Level I trauma center, in the years 2002 to 2005, more than twice as many patients needed tertiary care for severe injuries caused by off-road vehicle crashes compared with the previous 4 years. CONCLUSIONS: There has been an alarming increase in the number of both ATV and ORMC riders requiring treatment in Oregon's trauma centers. Surgeons need to join a coalition of health care providers, citizens and public officials to implement a comprehensive injury-prevention response to this epidemic.     

Predictors of mortality in patients with traumatic diaphragmatic rupture and associated thoracic and/or abdominal injuries

This is a retrospective review of 731 patients sustaining diaphragmatic trauma over a 22 year period (1980-2002) at an urban level I trauma center. Patients had an average injury severity score (ISS) of 22 +/- 12. The mortality rate (MR) was 23 per cent (168/731). There were a total of 460 left-sided diaphragmatic injuries (L-TDR), 263 right-sided diaphragmatic injuries (R-TDR), and 8 bilateral diaphragmatic injuries (B-TDR). There were no significant differences in mortality with L-TDR versus R-TDR. Shotgun wounds had the highest MR (42%) (P = 0.0028). Emergency thoracotomies were performed in 31 per cent (225) with a 62 per cent (140) MR. Bilateral thoracotomies had a significantly higher MR of 85 per cent (33/39) compared to the 58 per cent (107/186) for unilateral thoracotomies (P = 0.0028). Multivariate analysis revealed the most significant independent predictors of mortality to be the revised trauma score, transfusion of pRBCs > 10 units, and need for thoracotomy (P < 0.0001). The infection rate was 41 per cent. Multivariate analysis revealed blunt trauma, blood transfusions, ISS, and pancreatic injury as the most significant independent predictors of infection (P < 0.001). The initial physiologic presentation of the patient and the severity of hemorrhagic shock are the primary determinants for survival. Prompt identification of associated injuries with rapid control of bleeding is paramount to survival.     

Pediatric blunt trauma: a retrospective analysis in a Level I trauma center

This study consisted of an 8-year retrospective trauma registry analysis of blunt trauma and comprised of 2458 children (<18 years of age) and 4568 adults (18-64 years of age). Falls and motor vehicular crashes were seen in 30.4 per cent (749) and 23 per cent (566) of children, and 25.4 per cent (1158) and 41.9 per cent (1914) of adults. Children had a higher mean revised trauma score (7.69 vs 7.66) and Glasgow Coma Score (14.5 vs 14.3), and a lower Injury Severity Score (ISS; 6.68 vs 7.83 and hospital length of stay (2.8 vs 3.8 days) with P < 0.05. Overall mortality was 1.3 per cent in children and 1.9 per cent in adults (P = 0.05). Pedestrian accidents resulted in a 3.8 per cent (6/161) mortality rate. Pediatric nonsurvivors had a 6.4-fold higher ISS than survivors compared with a 5.2-fold increase in adults. Mortality progressively increased with higher ISS; 0.09 per cent in <15, 1.3 per cent, in 15 to 24, and 17 per cent in children with > or = 25 ISS. Mortality in multiple chest injuries was 19 per cent. The presence of chest trauma resulted in a 46-fold higher mortality in children. Most lethal injuries were combined head, chest, and abdomen trauma with a 25 per cent mortality in children and 28 per cent in adults. Admission Glasgow Coma Score <9 and systolic blood pressure below 100 mm Hg carried high mortality: 39 and 6 per cent in children vs 31 and 24 per cent in adults. Ninety-seven per cent of children and 89 per cent of adults were discharged home.     

Changing patterns of severe craniomaxillofacial trauma in Auckland over eight years

BACKGROUND: This study was performed to review the changing pattern of incidence of severe craniomaxillofacial (CMF) trauma in Auckland over 8 years (1989-1997) and to audit the involvement of the regional plastic surgery service. METHODS: A review of prospectively collected admission data of patients admitted to the Auckland Hospital Department of Critical Care Medicine (DCCM) with severe CMF trauma during 1997. A comparison is made with similar data from 1989. Injury severity was defined using the Injury Severity Score (ISS). RESULTS: Twenty-six patients with severe CMF trauma were admitted to Auckland Hospital DCCM in 1997. Their average ISS was 35. Eighty per cent had a significant head injury. Sixty-two per cent had injuries due to road traffic accidents (RTA) and 42% had positive blood alcohol levels, including 37% of the RTA victims. Twenty-three per cent had their surgical care provided by the regional plastic surgery service. In 1989, 55 patients were admitted to DCCM with severe CMF trauma. The average ISS was 36. Ninety-five per cent had a significant head injury. Seventy-three per cent had injuries due to RTA and 55% had positive blood alcohol, including 60% of the RTA group. CONCLUSIONS: Patients with severe CMF trauma make up a significant proportion of trauma admissions to DCCM and have a high incidence of life-threatening injuries. A multidisciplinary approach is essential. The nature and severity of these injuries has not changed over the last decade. There has been a clear decrease in the incidence of these injuries. This seems to be due to a profound decrease in the rate of RTA associated with alcohol intoxication.     

All-terrain vehicle riding among youth: how do they fair?

Purpose

Pediatric all-terrain vehicle (ATV) injuries have been increasing annually for more than a decade. The objective of this study was to describe the riding behaviors, helmet use, and crash history of young ATV riders.

Methods

A 38 question self-administered survey was distributed to a convenience sample of children at 4 agricultural fairs during 2007. A total of 228 surveys were reviewed. Collected data included demographic information, ATV characteristics, helmet use, driving habits, and crash history.

Results

Survey respondents were predominantly male (71%) with an average age of 13.6 ± 2.0 years. Riding began at a young age (9.2 ± 3.2 years). Few children reported using age-appropriate sized engines (3% < 90 cm³), and 22% of children rode ATVs with engines more than 300 cm³. Respondents rode primarily for recreation (94%), and more than a third reported riding without a helmet (40%). More than 70% of children reported riding with passengers, 60% without adult supervision, and nearly half (46%) rode after dark. Less than 5% of riders received any formal ATV riding/safety instruction. Of the respondents, 45% reported being involved in an ATV crash. Those children who reported a crash also rode more powerful ATVs, were more often self-taught, and overall reported higher rates of riding with passengers and without supervision, and riding after dark (P < .05).

Conclusion

Dangerous driving behavior among children who ride ATVs is widespread, and current safety recommendations are largely ignored. Renewed efforts are needed to improve safety programs and create policy measures that prevent pediatric ATV crash-related injuries.     

An appraisal of trauma in the elderly

To review the trends of trauma in the elderly experienced at our trauma center compared with other Level I trauma centers. This was a retrospective trauma registry analysis (1996-2003) of 2783 blunt trauma in elderly (BTE) and 4568 adult (BTA) patients in a Level 1 trauma center. Falls and motor vehicular crashes were the most common mechanisms noted in 47 per cent and 31 per cent (84% and 13% in BTE, 25% and 42% in BTA). BTE were sicker, with higher Injury Severity Scores (ISS), lengths of stay, and mortality (5% vs 2%, P value < 0.05). ISS was 5.2-fold higher in nonsurvivors to survivors in BTA and 2.4-fold in BTE. Elevation in ISS resulted in higher linear increase in mortality in BTE (vs BTA) at any ISS level. Mortality in patients with ISS > or = 25 was 43.5 per cent vs 23.8 per cent. ISS > or = 50 had 31 per cent adult survivors but no elderly survivors. Among isolated injuries, head trauma in the elderly carried the highest mortality, at 12 per cent (19% in patients with an Abbreviated Injury Score > or = 3). Abdominal injuries were the most lethal (18.3% and 41.2% in patients with an Abbreviated Injury Score > or = 3) in multiple trauma victims (41% vs 18% in isolated trauma). There was 4.4-fold increased mortality in the presence of thoracic trauma. Combined head, chest, and abdominal trauma carried the worst prognosis. Thirty-four per cent of BTE and 88 per cent of BTA patients were discharged home. Elderly patients need more aggressive therapy, as they are sicker with higher mortality.     

Comparison of severity and pattern of injuries between motorcycle riders and their pillions: A matched study

Introduction

Motorcyclists and their pillion riders are the most vulnerable group of road users in Singapore, accounting for 50% of all road traffic accident fatalities in 2011. This study aims to compare the severity and pattern of injuries between matched pairs of riders and pillions.

Methods

Thirty-two matched pairs who presented to the A&E of an urban hospital from 1 August 2011 to 20 March 2012 were enrolled. Data were obtained from the hospital's trauma registry records, clinical records and accident victims were interviewed individually. Analysis was done using Stata 10 and considered rider-pillion pairs.

Results

Thirty-one pairs agreed to participate. There was no statistically significant difference in the ISS between riders and pillions (p = 0.25). There was no significant difference in the probability of survival, Revised Trauma Score, distribution of injuries, total duration of admission and ICU stay between riders and pillions. When one party of the matched pair sustained a head, face, thoracic, abdominal/pelvic, extremity or external injury, the likelihood that the other party had an injury in the same region was 31%, 14%, 10%, 14%, 56% and 68% respectively. Cohen's kappa values were 0.28, 0.15, 0.05, 0.17, 0.24 and −0.16 for the respective regions.

Discussion

By comparing the severity and pattern of injuries between naturally matched pairs on the same motorcycle, one can account for potential confounding by the type and impact of collision, rider experience, amount of time to availability of medical aid, and other factors that may influence the outcome. Our study shows no statistically significant difference in the ISS and distribution of injuries between riders and pillions of matched pairs. Therefore, future health and insurance policies should provide equal coverage for both riders and pillions. Medical practitioners should approach riders and pillions similarly as there is no significant difference in their injury distribution. When one party of a matched pair presents with a head, extremity or external injury, care should be taken to look for an injury in the same region in the other party.

Conclusion

Our study shows that there is no statistically significant difference in the ISS of riders and pillions. The pattern of injury is also similar. This study provides us useful information in the clinical management of motorcyclists and their pillions.
