Characteristics of kangaroo-related motor vehicle crashes. Injury 2022; 53:3025-3029. [PMID: 35811153 DOI: 10.1016/j.injury.2022.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 05/28/2022] [Accepted: 06/08/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Kangaroo-related motor vehicle collisions are common but there is limited literature on this topic. Drivers confronted by kangaroos may choose to swerve or to directly collide with the kangaroo. The effect of these differing crash mechanisms, along with the effect of vehicle type or time of day, has not yet been reported. METHODS A retrospective cohort study was performed, examining patients admitted to our tertiary trauma centre for kangaroo-related motor vehicle collisions between 2000 and 2020. Data on patient demographics, crash characteristics, and hospital stay were collected and analysed. RESULTS A total of 366 patients were included and were predominantly male (76%) with an median age of 40. Swerve crashes were more common (59%) than direct impact and swerving was a statistically significant predictor of reduced injury severity score on multivariable analysis (other significant factors were female sex and no rollover). Motor vehicle crashes and motorbike crashes had differing crash characteristics. Motor vehicle crashes were more likely the result of swerving, and swerving was less likely to cause ejection or require extrication but more likely to cause rollover. Motorbike crashes however, were more likely the result of head on collision and riders were more likely to be ejected from the vehicle, require extrication, or be involved in a rollover. In terms of time of day, there were more crashes at dawn and there was a trend towards higher injury severity score and length of stay for night-time crashes. CONCLUSION For kangaroo-related motor vehicle crashes, predictors of increased injury severity score on multivariable analysis were male sex, direct impact, and rollover. Motorbikes and motor vehicles had differing crash mechanisms and characteristics, as did night-time crashes when compared to daytime or twilight crashes. LEVEL OF EVIDENCE IV, prognostic.

Abstract
A search was undertaken of the Forensic Science South Australia (FSSA), Australia, autopsy database over a 20-year period from 2000 to 2019 for all cases where vehicle crashes had involved kangaroos. There were six cases with an age range of 18-62 years (M=42 years) and a male-to-female ratio of 5:1. There were three crashes involving motor vehicles and three involving motorcycles. The three motor-vehicle crashes were initiated by impact with a kangaroo followed by a head-on crash with a truck (n=1) and a tree (n=2). In two of the motorcycle crashes, the cycle hit a kangaroo, resulting in the rider being unseated. In the third case, following impact with the animal, the cyclist hit a tree. In one of the latter cases, the only evidence of impact with a kangaroo was fur found by investigating officers adherent to the front-right indicator. Lethal injuries were located in the chest in six cases, the cranio-cervical region in five cases and the abdomen in three cases. Thus, in the majority of cases (n=5), death was due to multiple injuries. In the remaining case, death was caused by blunt chest trauma. This study shows that kangaroo-vehicle impacts may result in very significant blunt-force trauma. Motorcycle riders are particularly vulnerable. It may be only by careful examination of the vehicle/motorcycle for animal residues that the nature of the incident will be clarified.

Abstract
OBJECTIVE Non-fatal injuries sustained from animal-vehicle collisions are a globally under-recognised road safety issue, with limited data on these crash types. The present study aimed to quantify the number and causes of major trauma events resulting from animal-vehicle collisions. METHODS The study was a retrospective analysis of major trauma cases occurring in Victoria, Australia, between 2007 and 2016, using data from the population-based Victorian State Trauma Registry. To identify animal-vehicle collisions, Victorian State Trauma Registry injury codes were combined with text-mining of the text description of the injury event. RESULTS Over the 10 year period, there were 152 major trauma patients who were admitted to Victorian trauma-receiving hospitals due to vehicle collisions with animals. The crude population-based incidence rate for animal-vehicle collisions increased by 6.7% per year (incidence rate ratio 1.07; 95% confidence interval 1.01-1.13; P = 0.02). CONCLUSION Development of systematic recording methods of animal-vehicle collisions will improve reporting of these crash types to assist future studies in implementing effective countermeasures.

Abstract
Context The presence of large mammals on roads poses a serious risk to both the animals and motorists if collisions with vehicles occur. Fencing roads can reduce this risk, and it also limits the landscape-scale movements of animals. By also constructing fauna underpasses it may be possible to avoid collisions with vehicles, while, at the same time, allowing the natural movement of animals across the landscape. Aims We aimed to determine whether western grey kangaroos (Macropus fulignosus) would use fauna underpasses and to determine how this may affect their home range. Methods We used motion-activated infrared cameras to monitor the use of one large 8 × 3 m arched underpass and two 0.9-m-diameter fauna underpasses over 342 days between March 2011 and March 2012. The underpasses were situated between reserves separated by a four-lane fenced highway, with one reserve surrounded by residential properties. At the same time, 20 kangaroos (10 males and 10 females) were radio-tracked to determine the size of their home range and to test whether the animals incorporated the fauna underpasses into their daily movements. Key results The large fauna underpass was used 3116 times by individual kangaroos in groups of up to 21 animals, whereas the two smaller underpasses were used only twice. In total, 14 of the 20 radio-collared kangaroos used the large underpass over the course of the study, but underpass use did not affect home-range size. Kangaroos that did not use the underpass had a significantly higher proportion of their home range on residential properties surrounding one of the reserves than did those kangaroos that used the underpass. Conclusions The use of the underpass did not affect the size of the home range of the kangaroos, but it allowed the kangaroos to access grazing areas that would have been otherwise inaccessible. Fauna underpasses allow the safe passage of kangaroos between isolated remnant vegetation patches and may reduce significantly the risks posed to motorists and kangaroos from collisions. Implications Fencing roads and constructing fauna underpasses is a viable solution to reducing some of the problems of managing large kangaroos in peri-urban areas.

Abstract
Context Fertility control of females with levonorgestrel or deslorelin implants shows promise for managing populations of overabundant eastern grey kangaroos (Macropus giganteus). Although these implants have been tested separately in captive and free-ranging kangaroos, there has been no direct comparison under equivalent field conditions. Aims We investigated the long-term efficacy of levonorgestrel and deslorelin implants, together with the cost of treatment, ease of administration, and the welfare of the animals, in a side-by-side trial under realistic management conditions. Methods We captured 65 adult female kangaroos over 11 days at a golf course in Anglesea, Victoria, Australia. We assigned each female to one of the following three experimental groups: levonorgestrel (210 mg, n = 18), deslorelin (9.4 mg, n = 24) or procedural control (n = 23). We monitored reproductive success for 8 years, by observing young in the pouch in winter and spring. Key results Natural fertility was high; in most years, less than 20% of control females failed to reproduce. For deslorelin-treated females, the odds of failing to reproduce were four times higher than for the control group; for levonorgestrel-treated females, these odds were 74 times higher. Deslorelin was ineffective after 3 years, whereas levonorgestrel was effective for at least 5 years. Conclusions Levonorgestrel was markedly superior in efficacy, as shown by a stronger contraceptive effect persisting for longer. In other respects, the two implants were comparable, being similar in cost and ease of delivery, and equally safe. Implications Only levonorgestrel implants fulfill their promise for non-lethal, long-term control of kangaroo populations. Deslorelin implants cannot be recommended for this purpose.

Abstract
Critical illness intersects with the workload of rural doctors in Australia, mostly via their on-call responsibilities to rural hospitals. A significant proportion of these are prehospital incidents - vehicle crashes, farming injuries, bushfire etc. Effective care for such patients requires an integration of prehospital ambulance services, retrieval services and tertiary level trauma services all the way through to rehabilitation. Ambulance services in rural areas are often volunteer based, and with increasing remoteness via the 'tyranny of distance' comes the likelihood of increased delay in arrival of specialist retrieval services. Potential exists to utilise rural clinicians to respond to prehospital incidents in certain defined circumstances, as suggested by a recent survey of rural doctors.

Abstract
Understanding the impacts of roads on wildlife and the natural environment is of increasing importance. Macropods (mostly kangaroos and wallabies) are a diverse and widespread taxon in Australia that has been significantly affected by the presence of roads in various ways. We reviewed the available literature on macropods and roads, assessing 60 scientific journal articles, reports and theses. Studies on road mortalities were the most prevalent (n = 29, with 12 on macropods only), revealing both spatial and temporal patterns in occurrence. Behavioural studies in relation to the road environment are limited (n = 2) yet could help our understanding of patterns of road-kill and other impacts. Some macropod populations are critically affected by the presence of roads (e.g. brush-tailed rock-wallaby, Petrogale penicillata) due to either proportionately high road mortalities and/or population fragmentation, and may face continued decline unless effective road-mitigation measures are implemented. Investigations of various types of road mitigation focussed on wildlife-exclusion fencing and road crossing structures as the most effective option, although the high cost of these measures appears to limit their implementation. Further research into several areas was identified, particularly on species where severe road impacts are likely to result in population declines.

Abstract
BACKGROUND Camel-related injuries have been less well studied than other animal-related injuries. We aimed to study prospectively the incidence, mechanism, distribution of injury, and outcome of patients admitted to hospital with camel-related injuries in Al-Ain, United Arab Emirates. METHODS All patients who were admitted to Al-Ain Hospital with a camel-related injury were prospectively studied during the period of October 2001 to January 2010. Patient's demography, time of injury, mechanism of injury, and distribution and severity of injury were studied. RESULTS A total of 212 patients, all male, with a median age of 28 years (5-89 years) were studied. The estimated incidence of hospitalized camel-related injured patients in Al-Ain City was 6.88 per 100,000 population per year. Camel kicks were most common (36.8 %) followed by a fall from a camel (26.4 %) and camel bites (25.0 %). Camel kicks and falling from a camel were more common during the hot month of August, and camel bites were more common during the rutting season (November to February). Patients with a kick-related injury had a significantly higher rate of maxillofacial fractures compared with other mechanisms. Spinal injuries occurred significantly more often in vehicle occupants who collided with camels compared with other mechanisms (3/7 compared with 7/205, p = 0.0022, Fisher's exact test). Twelve patients (5.7 %) were admitted to the intensive care unit. The mean hospital stay was 8.6 days (1-103 days). Two patients died (overall mortality 1 %). CONCLUSIONS Understanding the biomechanisms and patterns of injury and correlating them with the behavior of the camel is important for identification and prevention of camel-related injuries.

Abstract
PURPOSE To prospectively study the incidence, mechanism, distribution of injury, and outcome of patients admitted to Al-Ain Hospital with camel bite injuries in Al-Ain, United Arab Emirates. METHODOLOGY All patients admitted to Al-Ain Hospital with a camel bite were prospectively studied during the period of October 2001-October 2007. Patient's demography, mechanism of injury including behaviour of the camel, distribution and severity of injury, and outcome were studied. RESULTS 33 patients were studied having a median (range) age of 27 (10-58), all were males. 97% were from the Indian subcontinent. A majority of injuries (73%) occurred during the camel rutting season (November-March). Twenty-five patients were camel caregivers whilst five were camel jockeys. All camel jockeys were children. Seven patients were raised up by the camel's mouth and thrown to the ground whilst 26 patients were only bitten. Most injuries were in the upper limb (64%) and head and face (15%). 48% of upper limb injuries had associated fractures. Two patients who were bitten at the neck were admitted to the ICU. One of these died due to massive left-brain infarction and the other had complete quadriplegia due to spinal cord injury. The median hospital stay was 6 days. There was only one death (3%). CONCLUSION The behaviour of the camel is occasionally unpredictable, especially during the rutting season. The mechanism of camel bite injuries, which are usually severe, are complex including penetrating and crushing injuries by the camel jaw and blunt injuries when patients are picked up and thrown away. Care should be taken when handling camels, particularly in the rut.

Abstract
Animals may be responsible for an array of potentially lethal injuries. Blunt force injuries characteristically involve larger animals such as cattle or horses that may kick, crush, or trample a victim causing head and facial injuries. Farm workers in particular are at high risk of lethal injuries involving the head and torso. Significant blunt trauma may be found in vehicle occupants after collisions with large animals such as camels or moose. Rarely, zookeepers may be crushed by particularly massive animals such as elephants. Sharp force injuries usually involve carnivore bites, most often from dogs with a "hole and tear" pattern of wounding. Injuries from animals such as alligators and sharks may have a significant component of crushing. Incised wounds may result in death from exsanguination and air embolism. On occasion, blunt or sharp trauma from animal activity may be confused with postmortem damage or with inflicted injury from an assault.

Abstract
BACKGROUND Our American College of Surgeons Level 1 Trauma Center serves a rural population. As a result, there is a unique set of accidents that are not present in an urban environment such as deer related motor vehicle crashes (dMVC). We characterized injury patterns between motorcycle/all-terrain vehicles (MCC) and automobile (MVC) crashes related to dMVC (deer motor vehicle crash) with the hypotheses that MCC will present with higher Injury Severity Score (ISS) and that it would be related to whether the driver struck the deer or swerved. METHODS The records of 157 consecutive patients evaluated at our institution for injury related to dMVC from January 1st, 1997 to December 31st, 2006 were reviewed from our prospectively collected trauma database. Demographic, clinical, and crash specific parameters were abstracted. Injury severity was analyzed by the Abbreviated Injury Scale score for each body region as well as the overall Injury Severity Score (ISS). RESULTS Motorcycle crashes presented with a higher median ISS than MVCs (14 vs 5, p < 0.001). Median Abbreviated Injury Score (AIS) of the spine for MCC riders was higher (3 vs 0, p < 0.001) if they swerved rather than collided. Seventy-seven percent of riders were not wearing a helmet which did not result in a statistically significant increase in median ISS (16 vs 10), head AIS (2 vs 0) or spine AIS (0 vs 0).Within the MVC group, there was no difference between swerving and hitting the deer in any AIS group. Forty-seven percent of drivers were not wearing seat belts which resulted in similar median ISS (6 vs 5) and AIS of all body regions. CONCLUSIONS Motorcycle operators suffered higher ISS. There were no significant differences in median ISS if a driver involved in a deer-related motor vehicle crash swerved rather than collided, was helmeted, or restrained.

Abstract
Each year in Australia many thousands of collisions occur between motor vehicles and animals, resulting in considerable vehicle repair costs, injury to persons, and loss of animal life. This paper reviews animal-related road crashes in Australia and presents data from the in-depth Rural and Remote Road Safety Study in North Queensland for serious casualties (n=33) resulting from direct impact with an animal or swerving to avoid an animal on public roads. These crash types accounted for 5.5% of all eligible on-road serious casualties in the study and, hence, are considered to be an important issue that requires particular attention within rural and remote areas. Kangaroos and wallabies were the predominant species involved in these crashes (44.8%). Consistent with international studies, night-time travel was found to be a significant risk factor when comparing animal-related crashes to other serious injury crashes in the study. There were also a significantly higher proportion of motorcyclists (51.7%) than other vehicle occupants involved in animal-related serious crashes compared to all other serious injury crashes. Data matching to official Government records found underreporting of animal-related crashes to be an issue of concern. These findings are discussed in terms of countermeasures suitable for the Australian context and the need for consistent crash reporting across jurisdictions.

Abstract
Kangaroo–vehicle collisions are frequent on Australian highways. Despite high economic costs, detrimental effects on animal welfare, and potential impacts on population viability, little research has been done to investigate the impact of road mortality on kangaroo populations, where and why accidents occur, and how the collisions can be mitigated. We therefore collected data on species (Macropus rufus, M. giganteus, M. fuliginosus, M. robustus), sex and age of kangaroos killed on a 21.2-km bitumenised section of outback highway over 6 months in far western New South Wales, Australia. The spatial and temporal distribution of road-killed kangaroos was investigated in relation to the cover and quality of road-side vegetation, road characteristics, the density of kangaroos along the road, climatic variables and traffic volume. A total of 125 kangaroos were found killed on the road at a rate of 0.03 deaths km–1 day–1. Grey kangaroos of two species (M. giganteus, M. fuliginosus) were under-represented in the road-kill sample in comparison with their proportion in the source population estimated during the day. No bias towards either sex was found. The age structure of road-killed kangaroos was similar to age structures typical of source kangaroo populations. Road-kills mainly occurred in open plains country. In road sections with curves or stock races, road-kill frequencies were higher than expected. Greater cover and greenness of roadside vegetation at the verge probably attracted kangaroos to the road and variation in this vegetation affected the spatial distribution of road-kills. The temporal distribution of road-kills was positively correlated with the volume of night-time traffic. The probability of a kangaroo–vehicle collision increased exponentially with traffic volume. Results are discussed in relation to the potential for mitigation of kangaroo–vehicle collisions.

Abstract
A goal to reduce the frequency of animal–vehicle collisions is motivating extensive research on this topic world-wide. Over the last 30 years, one popular mechanism to warn wildlife of approaching vehicles has been the wildlife warning reflector, manufactured and distributed under the brands Swareflex (Austria) and Strieter-Lite (USA). These reflectors were designed to scare deer and other ungulates from roadways at night by reflecting light from the headlights of approaching vehicles into the eyes of animals on the road verge. Robust documentation of their effectiveness has been lacking, yet there has been a push in Australia to examine their efficacy with regard to medium to large macropodids. Field trials of the reflectors are problematic and difficult to design rigorously, so we chose to examine the behavioural response of two captive macropodid species (Macropus rufus and M. rufogriseus) to the reflectors on a simulated road in order to derive some indication as to their efficacy. The behavioural response to the reflectors was negligible for both species and not consistent with an aversive effect to deter road use or crossing. We conclude that they would be of little value in our efforts to reduce the frequency of collisions of kangaroos or wallabies with vehicles in Australia.

Abstract
Horse riding and handling are uniquely dangerous. Knowledge of the risk factors of horse-related injuries is essential to prevent them. We aimed to define the factors that affect the severity of horse-related injuries and the length of hospital stay. A number of 231 patients (136 females and 95 males) with horse-related injuries were studied. A generalized linear model was used to test the effect of age, sex, cause of injury, complexity of the mechanism of injury, year, place of injury and profession of the injured, on the injury severity score (ISS) and the hospital stay. Fall from a horse was the most common cause of injury (67%). Most of the patients were non-professional (153, 66%). Females were significantly younger than males (P<0.001, t-test). Statistical analysis showed that the primary mechanism of injury (F=2.73, P=0.014) and the complexity of this mechanism (F=4.47, P=0.013) significantly affected the duration of hospital stay. None of the studied variables affected the injury severity score. The mechanism of the horse-related injuries and their complexity significantly affected the duration of hospital stay but not the injury severity score.
