Epidemiology of yoga-related injuries in Canada from 1991 to 2010: a case series study

The aim is to describe the epidemiology of yoga injuries presenting to select Canadian emergency departments (EDs). Those who presented with a yoga injury to a Canadian ED participating in the Canadian Hospitals Injury Reporting and Prevention Program and had completed a data collection form between 1991 and 2010 were included. Demographic and injury characteristics were tabulated and injury profiles of children were compared to adults. Sixty-six individuals (48 female, 18 male) who sustained 67 injuries were included. The median age was 19 (intraquartile range: 13, 32) and 73% of individuals were injured after 2005 (p = 0.0003). Sprain was the most common injury (23/67, 34%) and the most common body region injured was the lower extremity (27/67, 42%). Significantly more children were injured while being instructed than adults (p = 0.003) but more adults required treatment (p = 0.023). Although yoga-related injuries presenting to an ED are not common, the number of injuries are increasing.     

Skiing and snowboarding injuries and their impact on the emergency care system in South Tyrol: a restrospective analysis for the winter season 2001–2002

Objectives. To evaluate the incidence and the pattern of skiing and snowboarding injuries in South Tyrol and their impact on the emergency medical system in the winter season 2001–2002 in an attempt to rationalize and improve the emergency care and assist in prevention strategies.

Methods. All medical records of patients referred to our emergency department (ED) that sustained a skiing or snowboarding injury during the study period were retrospectively reviewed. Age, sex, local or non-local residency, type of injury, data and time of accident, type of transport to the hospital, hospital admission or ED discharge, Injury Severity Score, outcome (including mortality) were evaluated. On site mortality data were obtained from the emergency call-center registry. Ski resorts utilization was estimated from the data published by the Regional Office of Cable Transport.

Results. For the period analyzed approximately 2,500,000 skier and snowboarder days were recorded in the whole region of which about 500,000 were attributed to the four nearby ski resorts that refer to our hospital. Of the 1087 patients, 794 were skiers and 294 were snowboarders. Snowboarders were younger than skiers (mean age 20 and 36 respectively, p = 0.001). Females were equally represented in the two groups. Male patients, children, senior skiers and non-local residents suffered from more severe injuries than their corresponding classes (p < 0.01, p = 0.002, p = 0.02, p = 0.000 respectively). Critical injuries (ISS ≥ 25) were homogeneously spread in the groups, with the exception of the non-local resident patients that showed a higher incidence (p < 0.02). No difference in severity was found between skiers and snowboarders. The incidence was 2.05 per 1,000 skier-days. Mortality rate was 1.6 per 1,000,000 skier-days. The pattern of injury was different: snowboarders showed more forearm and wrist trauma and skiers more lower extremity injuries. 208 patients were hospitalized and the mean length of stay was 4.5 days. Head trauma and fractures were the most common diagnosis of admission. The lack of field triage led to 12% of unjustified helicopter transfer and 9.6% of avoidable ambulance transport.

Conclusions. Incidence, pattern of injuries and mortality from skiing and snowboarding accidents in South Tyrol resemble those reported in other part of the world. Nevertheless, strategies for prevention are needed. The routine use of helmets should be enforced by law. Dangerous behaviors should be prosecuted. Skiers and snowboarders should be made aware that skiing beyond their technical ability can be life-threatening.     

Incidence and characteristics of unintentional injuries among children in a resource limited setting in Kampala,Uganda

ABSTRACT

Given that little is known about the epidemiology of unintentional injuries in children in low-income countries, this study sought to determine the incidence and characteristics of unintentional injuries among children aged ≤18 years in a slum community in Uganda. From a household survey, the incidence and odds ratios for factors associated with unintentional injury characteristics were calculated. Of 1583 children, 706 had suffered 787 unintentional injuries yielding an annual incidence rate of 497 injuries per 1000 children. Commonest injuries were cuts, bites or open wounds (30.6%) and bruises or superficial injuries (28.6%) with majority (75.5%) occurring at home. Boys were more likely to be injured at school (AOR 4.34; 95% CI 1.22–15.54) and to be injured from falls (AOR 1.41; 95% CI 1.01–1.96). Older children (12–18 years) were more likely to suffer from fractures (AOR 2.37; 95% CI 1.26–4.43), concussions and organ system injuries (AOR 3.58; 95% CI 1.03–12.39) and cuts, bites or open wounds (AOR 2.05; 95% CI 1.21–3.48). Older children were less likely to suffer burns or scalds as compared to the young children (AOR: 0.23; 95% CI 0.11–0.50). Unintentional injury incidence rate was high among children with most occurring in the homes.     

Injury rates and risk-factors associated with eventing: a total cohort study of injury events among adult Swedish eventing athletes

The aim of this study was to examine injury events and risk-factors among Swedish adult eventing athletes. A cross-sectional study design with retrospective recording of 1-year sports-specific exposure and injury data was used. The invited study population consisted of all members of the Swedish Equestrian Federation with eventing as their primary discipline (n = 513). The participation rate was 70.0%. The total 1-year injury prevalence was 26.6%; the specific 1-year prevalence of traumatic injury was 19.3% and of overuse injury 10.9%. The incidence of traumatic injury events was 0.54 injury events/1000 eventing hours (95% confidence interval (CI), 0.35-0.73 injury events/1000 eventing hours) for novices and 0.35 injury events/1000 eventing hours for qualified riders (95% CI, 0.21-0.49 injury events/1000 eventing hours). A total of 27.9% of the traumatic injury events led to severe injuries (causing more than 3 weeks absence from riding). Attitude to risk-taking was the only factor predicting an athlete becoming injured (p = 0.023), and qualification level was the only risk factor for additional injuries among injured riders (p = 0.003). Our results suggest that injury prevention programs in eventing should also give attention to overuse injuries and that care should be taken when eventing athletes are licensed into higher qualification groups.     

Feasibility of routine collection of injured worker occupational information in hospital emergency departments

The aim of this study was to examine injury events and risk-factors among Swedish adult eventing athletes. A cross-sectional study design with retrospective recording of 1-year sports-specific exposure and injury data was used. The invited study population consisted of all members of the Swedish Equestrian Federation with eventing as their primary discipline (n = 513). The participation rate was 70.0%. The total 1-year injury prevalence was 26.6%; the specific 1-year prevalence of traumatic injury was 19.3% and of overuse injury 10.9%. The incidence of traumatic injury events was 0.54 injury events/1000 eventing hours (95% confidence interval (CI), 0.35–0.73 injury events/1000 eventing hours) for novices and 0.35 injury events/1000 eventing hours for qualified riders (95% CI, 0.21–0.49 injury events/1000 eventing hours). A total of 27.9% of the traumatic injury events led to severe injuries (causing more than 3 weeks absence from riding). Attitude to risk-taking was the only factor predicting an athlete becoming injured (p = 0.023), and qualification level was the only risk factor for additional injuries among injured riders (p = 0.003). Our results suggest that injury prevention programs in eventing should also give attention to overuse injuries and that care should be taken when eventing athletes are licensed into higher qualification groups.     

Valuing consumer safety

Snowboarding is quickly becoming a popular sport at alpine resorts. In contrast to alpine skiing, where injuries to the knee and thumb are most common, the wrist (and forearm) and ankle are the most frequently injured body regions for snowboarders. Unfortunately, the rapid international growth of the sport has not been matched by detailed epidemiological evaluation of the injuries specific to snowboarding or the countermeasures to prevent them. The aim of this paper is to critically review the literature describing injury prevention measures, or countermeasures, for snowboarding. In doing so, it provides an evaluation of the extent to which these countermeasures have been demonstrated to be effective or associated with the occurrence of new types of injuries. Few countermeasures specific for snowboarding were found to have been formally evaluated. The countermeasures to which some attention has been paid are boots, bindings, wrist guards, skill level and methods of falling. Skill level and the other injury countermeasures apply more generally across the sport. Recommendations for countermeasure implementation include: education for snowboarders, adherence to snow conduct and safety codes, preparing snowboarders for their activity and maintenance of parks and runs. Recommendations for improved data collections include: standardising and maintaining existing data collections, collecting information about equipment used by snowboarders and monitoring injury trends. Further biomechanical and epidemiological research needs to be undertaken on knee/ankle and wrist/forearm injuries. Evaluation of countermeasures needs to keep pace with the rapid developments in this field. Particular attention should be directed towards evaluations of the role of wristguards, boots/bindings, fall technique and lessons in preventing injuries. Given the rapidly increasing popularity of the sport, the need for the safety equipment to be evaluated would seem to be a priority, along with identification of the mechanisms of injury.     

Child injuries in land vehicles that do not require restraints

Abstract

The goal of this study was to determine the injury profiles of Canadian children who presented to the Emergency Department from 1990 to 2016 due to an injury caused while traveling in a form of land transportation that did not require child restraint. A case series was conducted using data from the electronic Canadian Hospitals Injury Reporting and Prevention Program (eCHIRPP). Children who were injured while travelling on land transportation for which child restraint is not required, who presented to a Canadian Emergency Department that participates in eCHIRPP between April 1, 1990 to August 29, 2016, were included. Overall, 1856 children sustained 2139 injuries (mean age: 9.8?years (SD 4.5), 45.5% male). The majority of children were injured on a school bus (49.3%). The most commonly injured body part was the head or neck (52.6%). The most common type of injury was a superficial or open wound (33.1%), followed by traumatic brain injury (19.3%). Overall, 39.4% of injuries required no treatment in hospital. Overall, approximately 70 children presented to eCHIRPP EDs per year on a land transportation vehicle that does not require restraints. Biomechanical studies are needed to improve safety on land transportation vehicles that do not require seatbelts.     

Environmental risk factors contributing to traffic accidents in children: a case-control study

The aim of this study is to identify environmental risk factors related to road accidents in children of Tehran. This case-control study was performed in 2013. The cases were injured pedestrians aged 5–15 who were admitted to major hospitals supervised by Tehran University of Medical Sciences. The sample size for the cases was 273 and for the control group was 546. For the completeness of the clusters, 7 extra persons in case (total = 280) and 14 persons (total = 560) in control group were included. The interference of confounding variables assessed through forward conditional logistic regression. Result shows occurrence of traffic accidents was significantly associate with the width of the alleys or (<5 m: OR = 8.4, 95% CI: 3.3–21.5; 5–8 m: OR = 4.7, 95% CI: 1.8–12.2), distance from home to school((<100 m: OR = 1.7, 95% CI: 1.0–2.8), existence of parking lot (OR = 1.5, 95% CI: 1.0–2.3), traffic congestion (OR = 4.1, 95% CI: 2.6–6.4), traffic speed (OR = 2.1, 95% CI: 1.3–3.2) and existence of pedestrian bridges(OR = 4.2, 95% CI: 2.6–6.8). In the light of the important role of environmental factors in the occurrence of child traffic accidents, alleviating structural risk factors in addition to education and enforcement need more systematic efforts and planning by policymakers and urban planners to attain pedestrian safety goals.     

Incidence,patterns and risk factors for injuries among Ugandan children

There is limited epidemiological data on childhood injuries in developing countries. This study assessed the incidence, patterns and risk factors for injuries among children aged 0–5 years in Wakiso District, Uganda. To determine differences, chi-square and Wilcoxon rank sum tests were used. Risk factors were assessed using Poisson regression. Overall, information from 359 children of mean age 32 months (SD: 18.4) was collected. Annual incidence of injuries was 69.8 per 1000 children/year (95% CI 58.8–80.8). One fatal injury due to burns was reported. Incidence of injuries was less associated with being female (IRR: 0.56, 95% CI 0.34–0.90) and increasing age of the caretaker (IRR: 0.96, 95% CI 0.92–0.99). The high incidence of childhood injuries necessitates the need for interventions to reduce injuries among children.     

Unintentional injuries among youth with developmental disabilities in the United States, 2006–2007

We examined unintentional injury among youth with and without developmental disabilities. Our nationally representative sample included 6369 injured youth, aged 0–17 years, who were seen in one of the 63 US hospital emergency rooms that participated in the National Electronic Injury Surveillance System – All Injury Program (NEISS-AIP) in 2006–2007. Parents or guardians of injured youth were interviewed by telephone after the hospital visit to ascertain disability status. Denominator data were obtained from the National Health Interview Survey. Leading causes of injury were comparable for youth with and without disability. Injury rates (per 100 youth per year) were also comparable [10.4; 95% confidence interval (CI) 7.8, 13.0 and 10.5; 95% CI 8.2, 12.9, for youth with and without disability, respectively]. When examined by specific disability, the rate ratio for youth with learning disabilities versus youth without learning disability was 1.57 (95% CI 1.04, 2.10), which may represent a subgroup for targeted interventions.     

Severity of alcohol-related motor vehicle crashes in British Columbia: case - control study

The objective of the present study was to compare the injury severity and vehicle damage severity rates of alcohol-related crashes with rates of non-alcohol-related crashes in British Columbia (BC). Injury severity rates and vehicle damage severity rates were taken from 2002 Insurance Corporation of British Columbia traffic collision data. The data were computed in order to compare the differences in injury severity and vehicle damage severity rates of alcohol-related vs. non-alcohol-related motor vehicle crashes. Case - control methods were used in this study to analyse the risk of alcohol-related crashes compared to non-alcohol-related crashes in BC. Odds ratios (OR) and 95% CI were calculated to estimate relative risks. In the case - control analysis, the risk of fatal collision was increased for those drinking and driving compared with those driving sober (OR 4.70; 95% CI 3.15 - 7.01). Risk of injury collision was increased for those drinking and driving compared with those driving sober (OR 1.32; 95% CI 1.19 - 1.37). Importantly, the risk of vehicle damage severity was increased for those drinking and driving compared with those driving sober (write-off vehicle OR 4.24; 95% CI 3.70 - 4.86, severely damaged vehicles OR 1.98; 95% CI 1.77 - 2.21). The study reinforces existing literature to suggest that current evidence is sufficient to show an increased risk of injury and fatality to drivers and occupants in alcohol-related crashes. This paper not only emphasizes this well-known relationship, but also such consequences as increased vehicle damage severity. The connection between drinking and severity of motor vehicle crashes is popularly believed and has now received substantial scientific support. There is strong justification for injury prevention experts and policy-makers to step up motor vehicle crash injury prevention advocacy by implementing evidence-based policies to reduce rates of alcohol-impaired driving in the province of BC. Most unintentional injuries in BC are related to motor vehicle crashes. Significant improvements can be made in these statistics by: increasing the use of occupant protection (safety belt and child restraint seats); reducing alcohol-related injuries through multiple strategies including corrections in the physical environment, extensive enforcement of drinking and driving laws and health promotion/education.     

The association of light trucks and vans with paediatric pedestrian deaths

The hypothesis that relative to cars, light trucks and vans (including sports utility vehicles) are more likely to result in fatal paediatric pedestrian injury was investigated. It was further hypothesized that this increased risk is a result of head injuries. The study sample consisted of 18 117 police records of motor vehicles involved in crashes in which one or more pedestrians aged 5 to 19 years old was injured or killed. Frequencies and case fatality ratios for each vehicle body type were calculated. A logistic regression analysis was conducted, with light truck or van vs. car as the exposure variable and fatal/non-fatal pedestrian injury as the outcome variable. After controlling for driver age, driver gender, vehicle weight, road surface condition and presence of head injury, 5 to 19 year-olds struck by light trucks or vans were more than twice as likely to die than those struck by cars (odds ratio (OR) 2.3; 95% CI 1.4, 3.9). For the 5 to 9 year-old age group, light trucks and vans were four times as likely to be associated with fatal injury (OR 4.2; 95% CI 1.9, 9.5). There was an association between head injury and light trucks and vans (OR 1.2; 95% CI 1.1, 1.3). It was concluded that vehicle body type characteristics play an important role in paediatric pedestrian injury severity and may offer engineering-based opportunities for injury control.     

Compulsory child restraint seat law and motor vehicle child occupant deaths and injuries in Japan 1994-2005

The purpose of child restraint seats (CRS) is to reduce the number of individuals killed or injured in motor vehicle (MV) crashes. Japanese Road Traffic Law 17-3-4 (April 2000) specifies a requirement that CRS be used for all children aged 0-5 years. The objective of this evaluation was to determine the legislative impact on fatalities in Japan for the period 1994-2005. Data were obtained from the Institute for Traffic Accident Research and Data Analysis. A time-series Poisson regression model was used to analyse the change (6 years pre/post) in incidence rate ratios of fatality and injury in MV crashes among children ages 0-5 years. Despite increases in CRS use, fatalities failed to decrease significantly after enactment of the law (incidence rate ratio: 0.80; 95% CI: 0.49-1.31). In 2005, 67% of children aged 0-5 years, who were killed as MV occupants were not seated in CRS. Between 2000 and 2005, the lack of CRS led to 43% of front seat passenger deaths, 54% of rear seat deaths, 143 children died in total and 500 + children were seriously injured. It was found that the compulsory CRS law enacted in April 2000 did not result in a statistically significant reduction in child MV occupant fatalities and injuries in Japan.     

Pedestrian and motorists’ actions at pedestrian hybrid beacon sites: findings from a pilot study

The objective of the study was to examine the effects of overweight and obesity on times to recovery among Canadian youth who have suffered one or more types of injury. The data source was the 2002 Canadian Health Behaviour in School-Aged Children (HBSC) survey. The study population included 7266 youth in grades 6 through 10 sampled from all Canadian provinces and territories. Of these, 2831 students reported an injury event and were included in the analysis. Kaplan–Meier curves and hazard ratios (HR) were used to profile survival functions and estimate relative hazards for non-recovery from injury events among normal weight, overweight and obese youth. Youth who were obese and suffered a combined injury (broken bone and strain/sprain) took longer to recover (HR: 1.81, 95% CI 0.99–3.32) compared to normal weight youth. HR for injury recovery in obese youth were not significantly elevated for broken bones (1.15, 95% CI 0.61–2.19) and sprain/strains (1.17, 95% CI 0.73–1.85) in isolation. Obesity was associated with times for injury recovery among injured youth. If these findings are confirmed in other settings, clinicians providing an injury recovery prognosis may need to take into account BMI status and allow for extra recovery time for patients in this age range.     

Injuries sustained during snow removal from roofs resulting in hospital care

Clearing snow from roofs causes serious injuries annually. The aim of this study was to describe injury mechanisms, injury panorama, and injury incidence in connection to this activity. A specific aim was to study the association between snow depth and injury incidence. A total of 95 people were injured during four study periods. The risk of injury is strongly associated with snow depth, and the incidence varied up to 10-fold between the studied winter seasons. The majority of injuries (91; 96%) occurred during leisure time and only four people were injured in the occupational setting. The most common injury mechanism was falling off roofs or ladders of residential homes. Nearly 60% sustained moderate or serious injuries (Maximum Abbreviated Injury Scale [MAIS] 2–3), and fractures accounted for almost half of all injuries. Because roofs of single-family homes in Sweden usually do not require snow removal for heavy snow loads, these injuries may have been both unnecessary and avoidable. Further education is required to advise the public on the risks associated with snow removal from roofs.     

The association of psychological symptoms with unintentional injuries among retired employees of a university in China

To investigate the association of psychological symptoms with injury risk, psychological symptoms were measured using symptom checklist-90 revised (SCL-90-R) and the unintentional injury information was followed up for 1 year among retired employees at a university in China. The injury rate had a significant difference between groups of raw mean score > or =2.0 and <2.0 for SCL-90-R global factor and subscale factors of obsessive compulsiveness, interpersonal sensitivity, depression and anxiety. After accounting for the factors of daily housework, physical activities, living alone and demographic factors, SCL-90-R global factor (odds ratio (OR) = 1.87, 95% CI: 1.20-2.91) and subscales factors of obsessive compulsiveness (OR = 1.93, 95% CI: 1.31-2.85), interpersonal sensitivity (OR = 2.05, 95% CI: 1.09-3.02), depression (OR = 2.09, 95% CI: 1.40-3.12) and anxiety (OR = 1.58, 95% CI: 1.03-2.44) were still significantly associated with an elevated risk of unintentional injury among the retired employees. In order to reduce the risk of unintentional injuries among the elderly, a psychological health service should be provided in the community.     

Do overweight and obese youth take longer to recover from injury?

The objective of the study was to examine the effects of overweight and obesity on times to recovery among Canadian youth who have suffered one or more types of injury. The data source was the 2002 Canadian Health Behaviour in School-Aged Children (HBSC) survey. The study population included 7266 youth in grades 6 through 10 sampled from all Canadian provinces and territories. Of these, 2831 students reported an injury event and were included in the analysis. Kaplan-Meier curves and hazard ratios (HR) were used to profile survival functions and estimate relative hazards for non-recovery from injury events among normal weight, overweight and obese youth. Youth who were obese and suffered a combined injury (broken bone and strain/sprain) took longer to recover (HR: 1.81, 95% CI 0.99-3.32) compared to normal weight youth. HR for injury recovery in obese youth were not significantly elevated for broken bones (1.15, 95% CI 0.61-2.19) and sprain/strains (1.17, 95% CI 0.73-1.85) in isolation. Obesity was associated with times for injury recovery among injured youth. If these findings are confirmed in other settings, clinicians providing an injury recovery prognosis may need to take into account BMI status and allow for extra recovery time for patients in this age range.     

Vulnerability of motorcycle riders and co-riders to injuries in multi-occupant crashes

In developing countries, most motorcycles are ridden with more than one occupant. The objective of this study was to establish the relative vulnerability of riders and co-riders to injury and determine the injury risk factors in multi-occupant motorcycle crashes. Between January and December 2010, we collected crash and injury data from victims of multi-occupant motorcycle. It is a hospital-based study. The probability of sustaining injuries was similar for co-riders and riders, but co-riders were more likely to sustain severe injuries. Occupants of >2-occupant motorcycles were also more likely to be involved in risky behaviours like not wearing helmet and speeding than those on 2-occupant motorcycles. Occupants of motorcycles on which there were more than two occupants were at an increased risk of sustaining injuries compared with occupants of motorcycles with only two occupants (OR: 2.1, 95% CI: 1.1–4.3). Motorcycle co-riders were more vulnerable to severe injuries than riders. The significance of the study finding to prevention was discussed.     

How socioeconomic status influences road traffic injuries and home injuries in Rome

Road traffic injuries (RTI) and home injuries (HI) are a relevant public health problem, especially among people living in deprived areas. The objective of this study was to explore the relationship between morbidity, hospitalisation, mortality from RTI and HI, and socioeconomic status (SES) of the area of residence. RTI and HI surveillance based on the Emergency Information System, the Hospital Information System and the Mortality Registry of Lazio region are the three sources of this study to create a unique surveillance system. For each subject, the SES index (5 levels) of its census tract of residence was obtained. The study population included emergency department admissions (year 2005) of residents in Rome, Italy. Incidence Rate Ratios (IRRs) have been estimated using Poisson Regression. The rates of RTI and HI emergency department visits were higher among the most deprived level of SES (IRR = 1.27, 95% CI: 1.24–1.30; IRR = 1.33, 95% CI: 1.29–1.37, respectively) compared to the most privileged ones; a similar result was found for hospitalisation (IRR = 1.19, 95% CI: 1.08–1.32; IRR = 1.11, 95% CI: 1.01–1.22). A strong relation was found between RTI mortality rates and poor level of SES. The study concluded that RTI and HI incidence were associated to sociodemographic factors.
