The Abbreviated Injury Scale and its correlation with preventable traumatic accidental deaths: a study from South Delhi

Anatomic trauma scoring systems are fundamental to trauma research. The Abbreviated Injury Scale (AIS) and its derivative, the Injury Severity Score (ISS), are the most frequently used scales. In a prospective study, 400 autopsies of road traffic accident victims performed between January 2002 and December 2003 were coded according to the AIS and ISS methods. All the cases were classified into different injury groups according to the Injury Severity Scale. Fifty-eight cases (14.5%) were assigned an ISS value of <25; 244 (61%) cases were valued between 25-49; 38 cases (9.5%) were valued between 50-74 and 60 (15%) cases had a value of 75. On analysis of medical care, in cases with ISS<50, about 96% of the victims did not receive optimal care quickly enough with a lack of pre-hospital resuscitation measures and lengthy transportation time to hospital being of major importance.     

Gender-related traumatic deaths in Transkei: incidence and causes

This study is unique in that it strives to unfold, perhaps for the first time, the problem of female mortality due to trauma in the Transkei region of the Eastern Cape Province of South Africa. This study was carried out in the Umtata and Ngqeleni magisterial districts which have a combined population of about 400,000. Most of the people have very few resources and have historically relied on money repatriated by migrant workers. The objective was to establish the incidence and the causes of deaths due to gender-related trauma and to formulate recommendations which could probably help prevent or reduce these deaths. The study reviewed cases of female traumatic death during the period January 1993 to December 1999 that were brought to the mortuary in Umtata General Hospital (UGH). There were 1,054 (23%) traumatic deaths recorded in females between 1993 and 1999. Of these 486 (28%) were related to motor vehicle collisions, 219 (18%) due to gunshot injuries, 152 (19%) due to stab wounds and 139 (21%) as a result of blunt trauma. The male to female ratio was 3.3:1 in traumatic deaths. In homicides the male:female ratio was 4.4:1, gunshot 4.5:1, stab 4.2:1 and blunt injuries 3.7:1. In motor vehicle collisions (MVC's) the ratio was 2.5:1. There is an increasing incidence of traumatic deaths in women. Gun shot injuries are the commonest among traumatic deaths in females. This article recommends stricter measures to protect women in the form of legislation. Social uplifting and economic support should be carried out as part of the process of social change. In this case educating the entire community is necessary to safeguard women and their future survival.     

A profile of abdominal and pelvic injuries in medico-legal autopsy

Abdomino-pelvic region is vulnerable to injury in various forms of trauma. This study was undertaken with objectives to study the pattern and type of external and internal abdominal and pelvic injuries and to identify the risk organs in abdomen and pelvis susceptible to trauma among the medico-legal autopsies at the mortuary of a referral centre in eastern Nepal during the period of one year (n = 80). Males constituted 80% of the cases and the mean age of the victims was 30.76 years. The cause of trauma was Road Traffic Accident in 82.5%. The manner of death was accidental in 87.5% and homicidal in 11.25% cases. Liver (57.5%) was the most common organ injured followed by spleen in 37.5% cases. Multiple organs injury was seen in 67.5% and absence of any external injuries was noted in 31.25% cases. Autopsy can play a role in establishing the missed injuries and be helpful to widen the knowledge of the medical faculty in early diagnosis and management of such injuries.     

The epidemiology of back injuries in elite Gaelic football athletes: An 8-year prospective study

ObjectivesTo describe the epidemiology of back injury in elite male Gaelic football athletes between 2008 and 2016.DesignProspective cohort study.SettingInjury data from the National GAA Injury Surveillance Database.ParticipantsElite male Gaelic football athletes.Main outcome measuresIncidence of injury as a rate per 1000 h of exposure.Results38 datasets were analysed. Out of a total of 1606 time-loss injuries, 76 were back injuries (4.73%, 95% CI 3.80%–5.88%). The incidence of back injuries in match play was 1.72 (CI 95% 1.21 to 2.45) and in training was 0.2 (CI 95% 0.14 to 0.28) injuries per 1000 h of exposure. The majority of back injuries (63.16%, CI 95% 51.93–73.12) were new, as opposed to recurrent (35.53% CI 95% 25.7–46.74). Most back injuries were acute (51.32%, CI 95% 40.29–62.22), compared to chronic (31.58%, CI 95% 22.23–42.7) or overuse (11.84%, CI 95% 6.36–21.00). The majority of back injuries occurred during non-contact player activities (n = 60, 78.94% CI 95% 68.50–86.60).ConclusionsBack injury rates in Gaelic football are similar to soccer and Australian football but less than rugby union. Further research is needed to understand the factors leading to the onset and recurrence of back injury in Gaelic football athletes.     

Occupational fatalities in Jordan

ObjectiveOccupational fatalities are a worldwide problem. Certain occupations pose a greater risk than others. Recent statistics on global occupational injuries and diseases that might lead to temporary or permanent disability and even worse might lead to death, are staggering. The purpose of this study was to estimate the death rates from occupational injuries in Jordan over a period of four years; to estimate occupational fatality rate that results from accidental injuries and identify the most risky concurrent occupations with the type of injuries, the age and nationality of the victims.MethodA total of 88 work related fatalities were admitted to three hospitals in Amman through 2008–2012 and were examined by a forensic (occupational) physician at the time. They were categorized according to, age, nationality, occupation, type of injury and were all tested for toxic substances.ResultsThe occupation with the most fatalities was construction (44%); falling from a height was the commonest type of accident (44%) and head injuries were the leading injury type (21.6%); 9.1% of the deaths were positive for alcohol. Moreover, 22.7% of deaths were between ages of 25–29. Consequently, the mean occupational fatality rate was 2 per 100.000 workers during 2008–2012.ConclusionConstructions and other types of occupations are more extensive problems than what is usually anticipated, especially when safety precautions are not effective or implemented. They may cause injuries and death, which will have a socioeconomic burden on families, society, governments and industries. Not to mention the grief that is associated with the death of a worker at his work site to all concerned parties.     

Pediatric and adolescent injury in all-terrain vehicles

ABSTRACT

All-terrain vehicles (ATVs) remain a significant source of death and injury among youth. The purpose of this review is to provide an overview of the scope of the problem, the risk factors involved, crash-related outcomes and costs, and injury prevention strategies. There are currently more than 100 pediatric ATV-related fatalities each year and over 30,000 emergency department visits, with a potential annual cost for deaths and injuries approaching $1 billion. Major risk factors include lack of training, operating adult-size ATVs, riding as or carrying passengers, riding on the road, and not wearing a helmet. Extremity injuries are highly common, and the leading causes of death include brain injuries and multi-organ trauma. The latter increasingly involves being crushed by or pinned under the ATV. Reducing ATV-related deaths and injuries will require multiple strategies that integrate approaches from education, engineering, and evidence-based safety laws and their enforcement.     

Assaults in schools: Findings using a national data base

BackgroundAssaults can occur at schools/educational facilities involving students, teachers and other school employees. It was the purpose of this study to correlate injury patterns with patient demographics in school assault victims. Understanding injury patterns with their associated demographics will not only be useful for health care providers but can also assist in proposing prevention strategies for both students and school employees.MethodsEmergency department data from the National Electronic Injury Surveillance System All Injury Program data for the years 2005 through 2015 were used in this study. Statistical analyses were performed with SUDAAN software to account for the weighted, stratified nature of the data.ResultsThere were an estimated 852,822 ED visits for school assaults. The median age was 13.8 years with 81.3% between 5 and 19 years old; 64.4% were male. After age 4, the number of females proportionately increased with increasing age. The most common diagnosis was a contusion/abrasion (38.6%). The injuries occurred in the head/neck (63.9%), upper extremity (19.0%), upper trunk (6.6%), lower trunk (5.5%), and lower extremity (4.9%). Firearm violence accounted for 0.1% of the assaults. Human bites occurred in 3.7%. Sexual assault was rare and proportionally the highest in those ≤4 years of age. Internal organ injuries were more common in females (13.1% vs 3.55) and for those admitted to the hospital (29.9% vs 19.9%). The incidence of ED visits for school assault decreased 50% from 2005 to 2015.ConclusionsThis study analyzed ED visits due to assaults occurring in schools. Firearm violence accounted for only 0.1% of the injuries, in contrast to media coverage regarding school assaults. The most common injury location was the head/neck (63.9%) and the most common diagnosis was a contusion/abrasion. This data can also serve as a baseline for further studies and the impact of potential reduction strategies.     

Injury patterns and features of cycling fatalities in South Australia

There has been an increase in cycling in Australia. This means that more cyclists are at risk of injuries, which account for a proportion of transport-related fatalities. In this study, all cyclist fatalities from 2002 to 2013 in South Australia where post-mortem examinations were performed were investigated. There were 42 deaths representing 3% of the total road fatalities over the same time. Of this total number of cases, 13 deaths (31%) involved collapse (mostly natural causes from an underlying medical condition) and 29 (69%) resulted from trauma. There were no cases of hyperthermia. Of the decedents 95% were male, and the mean age at death was 47 years. Fatal incidents were more likely to occur during April and November, and on a Monday. However, statistical analysis was not possible due to the small number of cases. Fatalities (traumatic and collapse) predominantly occurred whilst the cyclist was riding (86%). The majority of riding fatalities were as a result of collision with vehicles (81%). Drugs (including alcohol) were detected in two (15%) of the 13 cases of the collapses, and in seven (26%) of the 27 trauma cases tested. In trauma cases, death was most often due to multiple injuries. The most frequent area for injury was the head (found in 90% of traumatic deaths). Despite the increasing numbers of cyclists on South Australian roads over the last decade, death rates have trended downwards suggesting that road safety campaigns and the provision of more dedicated bicycle lanes have had a positive outcome.     

Lethal injuries among the members of the 4th Guardian Brigade of Croatian Army during the 1991-1995 war

OBJECTIVE: We analyzed the causes of deaths among the members of the 4th Guardian Brigade (GB) of the Croatian Army during the war in Croatia from 1991 to 1995: the site of the lethal injuries, the type of wounds, and estimated the severity of injuries with lethal outcome according to the Abbreviated Injury Scale. METHODS: This was a retrospective study using the files and data obtained from 4th GB, Croatian Ministry of Defense, and Croatian Ministry of War Veterans. RESULTS: During the War in Croatia from 1991 to 1995, 182 members of 4th GB were killed. One hundred fifteen (63.2%) suffered lethal injuries caused by shell fragments, 47 (25.8%) soldiers had gunshot wounds, and 20 ( 11.0%) died in traffic accidents. Mean Abbreviated Injury Scale for killed soldiers was 7.61 +/- 1.27. CONCLUSION: During the war in Croatia, the leading causes of death were mines and explosions, and, in a minor proportion, gunshot wounds.     

Physical assault related injuries in Western Nepal – A hospital based retrospective study

ObjectiveThe study was carried out to study the pattern of injuries and epidemiological factors in Nepal where there is no systematic surveillance system for injuries.DesignA hospital based, retrospective study conducted by extracting data from the medico-legal register of the Emergency Department of a Regional Hospital for 3 years.SettingRegional Hospital in Pokhara, Western Nepal.ResultsA total of 1100 cases of physical assault had been reported. Male to female ratio was 3.6:1 and most commonly involved age group in males was 16–25 and in females was 26–35 years. Contusion (28.7%) was the commonest type of injury followed by incised wounds (25.7%). Most commonly used weapon was wooden stick and clubs (21.5%) followed by kicks and punches (20.6%). The most frequently affected anatomical site involved was the head and neck (57.06%), followed by the upper limbs (17.74%) and the lower limbs (10.5%). Assailants for females were most commonly spouse (40%) and in-laws (14%) and for males it was unspecified known individuals (18%) followed by neighbours (11%). Maximum number of physical assault injuries occurred between evening and midnight (59.59%).ConclusionInjuries from physical assault occurred in all age groups but most commonly affecting the young males and majority of them were in the productive age group. Commonest type of injury was contusion and weapon used wooden sticks and clubs. Assailants were spouses in females and known but unspecified individuals in men.     

Fatal injuries among motorcyclists in Klang Valley,Malaysia

BackgroundMotorcycle fatalities constitute the majority of road traffic deaths in Malaysia. The aims of this study were to describe the pattern of fatal injuries among Klang Valley fatal motorcyclists and to describe the factors associated with fatal (vs non-fatal) injuries.MethodsA cross-sectional analysis was performed on data from a case series of injured (fatal and non-fatal) motorcyclists recruited from Klang Valley between 14th March 2010 and 13th March 2011. Fatal cases in the cases series were identified from the Police files. Non-fatal cases were recruited from five major hospitals in the study region. Information used in the analyses were obtained from Police crash reports, hospital medical records, and Coroner's records of the participant sample.ResultsOf the 177 fatal cases, 142 (80.2%) were categorised as instantaneous death while 35 (19.8%) cases were categorised as experiencing delayed death. Thirty two percent of the cases had a Maximum Abbreviated Injury Score (MAIS) of 5 with head injury being the most common cause of death. Significant predictors of fatal (vs non-fatal) injury included ethnic groups, monthly income, alcohol and drug use and road type. Alcohol and drug use was shown to be the strongest predictor with adjusted odds ratio (AOR) of 14.77 (95% CI 3.32–65.65).ConclusionFactors related to the motorcyclists, road user behaviour and the road environment as well as pre-hospitalisation emergency care must be addressed efficiently in low and middle income countries to reduce the number and severity of motorcycle-related injuries.     

Pedestrian deaths following collisions with heavy goods vehicles

Pedestrian fatalities following collisions with heavy goods vehicles ('lorries') in south-east Scotland were studied between 1992 and 1998. Data sources included police and ambulance reports, forensic medicine records, hospital casenotes and the Scottish Trauma Audit Group database. All injuries were scored according to the Abbreviated Injury Scale, yielding Injury Severity Scores (ISS). Sixteen pedestrians (mean age 60.2 years) died after being hit by a lorry. Actions of pedestrians were implicated in causing all the collisions--four of which appeared to be suicides. Four of the apparently accidental deaths involved pedestrians with significant blood alcohol levels. Thirteen pedestrians were dead when found. Ten pedestrians had an ISS of 75, having a total of 13 injuries acknowledged to be unsurvivable (Abbreviated Injury Scale = 6), largely to the head and chest. The unsurvivable injuries reflect huge forces, explaining why only a small proportion of the pedestrians survived to hospital. There is little potential to reduce the number of deaths by improving hospital treatment, rather the focus needs to be directed towards injury prevention. Although pedestrians appeared to be responsible for the collisions, the results suggest it may be more feasible and effective to direct injury prevention measures towards lorry drivers.     

What are the differences in injury patterns of young and elderly traffic accident fatalities considering death on scene and death in hospital?

Older traffic participants have higher risks of injury than the population up to 65 years in case of comparable road traffic accidents and further, higher mortality rates at comparable injury severities. Rib fractures as risk factors are currently discussed. However, death on scene is associated with hardly survivable injuries and might not be a matter of neither rib fractures nor age. As 60% of traffic accident fatalities are estimated to die on scene, they are not captured in hospital-based trauma registries and injury patterns remain unknown. Our database comprises 309 road traffic fatalities, autopsied at the Institute of Legal Medicine Munich in 2004 and 2005. Injuries are coded according to Abbreviated Injury Scale, AIS© 2005 update 2008 [1]. Data used for this analysis are age, sex, site of death, site of accident, traffic participation mode, measures of injury severity, and rib fractures. The injury patterns of elderly, aged 65+ years, are compared to the younger ones divided by their site of death. Elderly with death on scene more often show serious thorax injuries and pelvic fractures than the younger. Some hints point towards older fatalities showing less frequently serious abdominal injuries. In hospital, elderly fatalities show lower Injury Severity Scores (ISSs) compared to the younger. The number of rib fractures is significantly higher for the elderly but is not the reason for death. Results show that young and old fatalities have different injury patterns and reveal first hints towards the need to analyze death on scene more in-depth.

     

Fatal burns in Manipal area: a 10 year study

The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burn injuries retrospectively. An analysis of autopsy records revealed 19.4% cases of burn injuries amongst the total autopsies done over 10years period (1993-2002) in the mortuary of the department of Forensic Medicine of Kasturba medical College, Manipal. The majority of deaths (78.5%) occurred between 11 and 40years of age group with preponderance of females (74.8%). The flame burns were seen in 94.1% of the victims followed by scalds and electrical burns in 2.8% and 2.5% cases, respectively. The majority of burn incidents were accidental (75.8%) in nature followed by suicidal (11.5%) and homicidal (3.1%) deaths. The percentage of burn (TBSA) over 40% were observed in most of the cases (92.5%). The majority of deaths occurred within a week (69.87%) and most the victims died because of septicemia (50.9%).     

Trauma angiography of the extremity: The impact of injury mechanism on triage decisions

A review of angiographic studies of 227 consecutive injured patients suspected of having sustained extremity arterial trauma was done to determine whether knowledge of the mechanisms of injury was of use in the establishment of priority in multiply injured patients. Stab wounds and other lacerations occurred in 32 patients. Major arterial injury occurred in only 3 (12%) cases; in no case was arterial occlusion present or limb viability threatened. These injuries may be angiographically evaluated on a nonurgent basis. Alternatively, patients with gunshot wounds (130 patients) and blunt injuries (63 patients) had a high incidence of major arterial injury (18 and 38%, respectively), especially arterial occlusion (15 and 24%, respectively) as well as a significant incidence of threatened limb viability (5 and 21%, respectively). Disproportionately increased risk of arterial injury occurred in patients with high-energy gunshot wounds (75%), motorcycle accidents (62%), and crush injuries (63%). Patients who sustain gunshot wounds or blunt injuries and have an abnormal vascular physical examination should be evaluated angiographically on an urgent basis.     

Injury patterns in peacekeeping missions: the Kosovo experience

Proper medical deployment planning requires projecting injuries. For this reason, the injury patterns and mechanism of injury were reviewed for an 18-month period in Kosovo, and injury rates and mechanisms were extracted for review. Overall, there were 404 trauma patients treated during the study period. Isolated head and neck injuries accounted for 29.5% (119) of injuries, chest wounds 5.7% (23), abdominal wounds 4.5% (18), and extremities 33.4% (135). Multiply injured patients accounted for the remaining 27.0% (109). When subdivided by mechanism, penetrating injury made up 36.9% (149), whereas blunt trauma accounted for 63.1% (255). Motor vehicle accidents made up the majority of blunt trauma (72.2%). Of penetrating injuries, gunshot wounds accounted for 55%, blast wounds 38%, and stabbings 6.7%. The data clearly demonstrate that humanitarian and peacekeeping missions require preparation for a wide variety of mechanisms of injury beyond the typical penetrating trauma of combat situations.     

Lightning fatalities in the Transkei sub-region of South Africa

Lightning is a particularly unsettling product of bad weather. It kills more people than other natural disasters such as floods, hurricanes, and tornadoes, but, because lightning usually kills people one at a time, it tends to be an underrated hazard. High risk groups are uneducated, unsheltered and rural people. This study was carried out to determine the incidence of lightning fatalities in the Transkei sub-region. It is a review of records between 1993 and 2004 from the medico-legal autopsies at Umtata General Hospital (UGH). During the study period there were 10,860 autopsies performed on those who died of trauma and other unnatural circumstances which included 151 (1.4%) lightning fatalities. This represents 0.31 deaths per million per year. The highest (0.5/million) was in 1999, and the lowest (0.13/million) in 1997. The age of the victims ranged from 1 to 82 years, with a mean of 22 years. Males and females were almost equally represented (50%). The highest number of deaths (26.5%) was in the age group of 11 to 20 years, and the lowest number (2.7%) in the age group of 70+ years. There is a high incidence of lightning fatalities in the Transkei sub-region of South Africa. People need to be educated to disregard the myths of lightning strike.     

Injuries in amateur soccer players on artificial turf: A one-season prospective study

BackgroundEpidemiological studies in soccer are important for injury prevention. However, most of the available information is limited to elite players.ObjectiveTo determine the epidemiology of injuries in amateur soccer players on artificial turf.DesignProspective cohort study during one competitive season (2010–2011).SettingAmateur soccer players. Participants: 231 players (aged 24.7; range: 18–38 years).Main outcome measuresInjury incidence was recorded prospectively according to the consensus statement for soccer.Results213 injuries were recorded; 57% of the players suffered injuries. Injury incidence was 5.1 (95% CI: 4.3–5.9) injuries/1000 h exposure. Injury incidence was higher in matches than in training (32.2 [95% CI: 23.1–41.3] vs. 2.4 [95% CI: 1.8–3.0] injuries/1000 h; p < 0.001). The thigh (22.1%), knee (20.2%), and ankle (19.2%) were the most affected regions. The most frequent diagnoses were thigh strain/muscle rupture (18.3%), and ankle and knee strain/ligament injury (17.3% and 11.3%, respectively). Time-loss due to injury was 20.3 (95% CI: 16.8–23.73) days. Most injuries (79%) were traumatic; 21% were overuse injuries. Re-injuries accounted for 10% of all injuries sustained during the season.ConclusionsInjury incidence in amateur soccer players is higher during matches played on artificial turf than during training sessions.
