The epidemiology of head injuries in Sweden from 1987 to 2000

The purpose of the present study was to evaluate the variability in the annual head injury incidence rate in Sweden from 1987 to 2000. It was hypothesized that the annual incidence rate would decrease over time due to a variety of primary preventive strategies that have been introduced in Swedish society. We used the Hospital Discharge Register at the National Board for Health and Welfare and head injury codes 800-804, and 850-854 from ICD9 system and S2.0-S2.9, and S6.0-S6.9 codes from ICD-10 system. We evaluated the patterns of age, gender, external cause of injury (E-code), type of injury, length of hospital stay, and trends over time. Head injuries due to transportation collision were reduced over the 14-year period analysis. Falls persisted as the dominant cause of head injury. Overall, men had 2.1 times the incidence of head injury compared to women. There was a decline in younger ages experiencing a head injury over this interval, while the number of head injuries among elderly people increased over time. Concussion was about three times more frequent than fractures. Hematoma and diffuse or focal contusions had a much lower incidence rate than concussion. Concussions and fractures decreased over time. Diffuse or focal injuries showed a steady rate of occurrence over the study interval while hematoma increased. Although length of hospital stay varied widely from zero to more than 50 days, 73.6% of hospital days were confined to two days or less. The incidence rate is stable over this time frame. While head injuries attributable to transportation accidents decreased, falls made up an increasing proportion of head injuries. Since we observed an increase in head injuries among elderly, primary prevention strategies may need to be targeted at this age group, and at preventing falls.     

A retrospective population-based data analyses of unintentional fall mortality and hospitalisation in Taiwan during 2005–2007

The objective of this study is to describe the epidemiology of unintentional fall mortality and hospitalisation and to find the risk factors associated with inpatient mortality. We analysed mortality data from official publications which record the vital statistics and hospitalisation data from National Health Insurance (NHI) Research Database from 2005 to 2007 and fall injuries were classified in accordance with ICD-9-CM E-Codes, including ‘falls on the same level (E885–E886)’, ‘falls on a different level (E880–E884)’ and ‘unspecified falls (E887–E888)’. We used SPSS 18.0 software. During 2005–2007 in Taiwan, there were 3555 deaths and 180,175 inpatients due to unintentional falls and the mortality rate was 5.19 per 100,000 and the hospitalisation rate was 236.14 per 100,000. With regards to deaths, different-level falls were the primary cause, and those aged 25 or more were high-risk groups; with regards to hospitalisation, same-level falls were the primary cause, and those aged 65 or more were the high-risk group. Associated factors for inpatient mortality can be classified by patient characteristics (older age, catastrophic illness, higher Charlson Comorbidity Index (CCI) and head trauma) and hospital-related factors (geographic area, type of hospital, level of hospital and department of care). The high-risk groups were different between ‘same-level’ and ‘different-level’ falls and the findings of this study will be beneficial for concerned authorities to draft up appropriate prevention plans in the future. Moreover, future researchers can further explore different risk factors for injuries using questionnaire surveys or hospital emergency room data.     

How well do anatomical-based injury severity scores predict health service use in the 12 months after injury?

There is an acknowledged need for valid and reliable injury scores, suitable for use at the population level, which can accurately predict the long-term outcome of injury. The objective was to quantify the extent to which the abbreviated injury severity score (AIS) and the functional capacity index score (FCI) predict use of health services in the 12 months following an injury event. A cohort of injured people (ICD-9-CM 800-995) aged 18 - 64 years was identified from Manitoba hospital discharge abstracts from January 1988 to December 1991. For each member of the cohort whose injuries could be mapped to an abbreviated injury scale unique identifier, a maximum AIS (maxAIS) and a maximum FCI (maxFCI) were obtained. The cohort was linked with hospital discharge abstracts, physicians' claims and deaths from the population registry for the 12 months following injury. Negative binomial regression was used to model the relationships between the severity scores and the three outcome measures, while controlling for potential confounding variables. In total, 20 677 (97%) eligible cases were identified, of which 16 834 (81%) could be assigned a maxAIS and 15 823 (77%) a maxFCI. MaxAIS and maxFCI were significantly associated with total days in hospital following injury, but explained little of the variation in any of the health service use outcome variables (maxAIS, partial pseudo r2 ranging from < 0.001 to 0.041; and maxFCI, partial pseudo r2 ranging from < 0.001 to 0.018). It was concluded that anatomical damage is only partly responsible for long-term injury outcome. Additional variables would need to be included in predictive models of health outcomes of injury before these models could be reliable.     

Injuries among preschool children in the federal state of Brandenburg in relation to social factors – 1997–1999

The aim was to determine the epidemiology and risk factors of childhood and young adult injuries among long-term Afghan refugees in Pakistan. A stratified cluster study was undertaken on a random sample of refugee households from June to July 2002. The Afghan Refugee Injury Survey was administered to the head of the household and recorded all injuries among household members within the last 3 months. Crude injury incidence was 12.3 per 1000 population among those aged 0?–?29 years (age groups 0?–?4, 5?–?14 and 15?–?29 years). Those aged 15?–?29 years had the highest injury rate (18.3 per 1000) closely followed by those aged 5?–?14 (12.3 per 1000) and much higher than the 0?–?4 years category (2.3 per 1000). Falls accounted for most injuries (48%) with both road traffic injuries and assaults accounting for 15%. The 15?–?29 year age group (odds ratio?=?9.1) and those educated informally or for less than 6 years (odds ratio?=?2.10), were associated with injury (p?相似文献   

Injury classification: balancing continuity and utility

The approach to classifying injury and its causes in the International Classification of Diseases changed radically between ICD5 and ICD6. It has changed relatively little in the subsequent four revisions and fifty years. ICD6 introduced separate chapters for “injury and poisoning” and “external causes”, and the main groups in each of those chapters. Injury research has emerged as a discipline in the period since ICD6 was developed. Major themes are conceptual frameworks of aetiology and prevention, the empirical measurement of injury severity, and population-based and community injury prevention techniques. ICD-10 (in common with ICD-9) reflects these developments to a very limited extent. A response to limitations of the ICD for purposes of injury prevention and control was the development, particularly in the 1980s and 1990s, of special-purpose classifications of characteristics of events that result in injury. Recognition of strong commonality among several of these ‘multi-axial’ systems led to a view that an international system embodying shared characteristics was achievable and worthwhile. The draft ICECI is the latest outcome of this work. Compatibility with ICD-10 is a design criterion for ICECI because of the continuing central importance of the ICD for health classification. The precise meaning of “compatibility” in this context has not been resolved. At one extreme, “compatibility” could mean limiting ICECI simply to the ICD-10 external cause codes with subdivision of existing categories, and perhaps some additional data items that do not overlap conceptually with ICD-10. At other extremes, ICECI could be developed without specific reference to categories in ICD-10, or ICECI could replace the existing ICD external cause classification. It is not practicable to map every ICD-10 three-character external cause category to a unique equivalent combination of codes in a multi-axial system, mainly due to conceptual inconsistencies in the ICD-10 external cause classification. More limited mapping is possible and could be designed to ensure that data coded to ICECI could be grouped to be equivalent to important ICD external cause categories. The way chosen for classification of external causes should be one that recognises contemporary information requirements in the fields of injury prevention and control as well as the desirability of continuity in long-term monitoring of important categories of injury. Field-testing and consultation with data users will determine whether ICECI meets these criteria well enough to warrant its adoption as a member of the ICD family of classifications.     

On the epidemiology of injury in developing countries: A one-year emergency room-based surveillance experience from León,Nicaragua

Background Regularly available data has been shown to be inadequate for developing, implementing, and evaluating injury prevention and control programs in Nicaragua. A specific prevention-oriented local injury surveillance system has therefore been set up in the city of León. Objectives The aim of this paper is to describe the epidemiology of fatal and non-fatal injuries over a one-year period in a well-defined local population in Nicaragua, as emerging from the perspective of emergency room and inpatient treatments over a one-year period. Methods A hospital-based injury surveillance system was established to collect data for different levels of severity. All treated unintentional and intentional injuries were registered, including information on the external causes according to the ICD-9. Results Of all emergency room visits, 15.9% (9,970) were injuries. For every death due to injuries, there were 31 hospital admissions and 253 emergency room visits. Home and street/roads were the main arenas for the accidents. The estimated underreporting rate was about 6%, and in 20.3% of the cases, no E-code was assigned. The overall incidence and mortality rates were 56.2 per 1,000 and 20 per 100,000 inhabitants, respectively. However, comparison with a parallel household survey showed that the reporting rate of the surveillance system is only about 9%. The overall ratio of male to female injury rates was 2.1 to 1. The main causes of non-fatal injuries were falls, whereas the main cause of death was traffic accidents. Conclusions Hospital discharge and emergency room data systems are effective and feasible means for collecting the data needed to prevent injuries. However, in a country like Nicaragua with limited access to hospital health services, it is necessary to supplement such a system with additional sources of information in order to gain a more comprehensive picture of injury occurrence.     

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.     

Morbidity and mortality from road traffic crashes in children in Metro West,City of Cape Town – 2014

The road traffic crash injury burden significantly impacts the lives of South African children. This study aimed to assess the fatal and non-fatal pattern of road traffic crash injury of children under 13 years old from Metro West, City of Cape Town, from 1 January until 31 December 2014. The data were stratified by age, sex and mechanism of road traffic crash. The overall mortality rate was 8.7 per 100 000 population and pedestrians contributed the most to this burden (72.5%). There were more male children involved in a road traffic crash (p?=?0.0001). The greatest proportion of fatal and non-fatal road traffic crash injuries was observed in children aged 5–9 years. Fractures contributed to the greatest rate of years lived with disability (3.0 years of life lived with disability per 100 000). Our study found that the burden of road traffic crashes primarily affects male pedestrians aged 5–9 years old.     

Costs of unintentional injuries among children in an urban slum community in Kampala city,Uganda

Abstract

Unintentional injuries cause deaths, disabilities, productivity and financial losses and disproportionately affect children in low-income settings yet their cost remains under studied. This study determined the household out-of-pocket expenditure and missed school attendance due to unintentional childhood injuries in a Ugandan slum. We used a cross-sectional household survey design. Data were collected on occurrence and associated costs of unintentional injuries during a one-year period from July 2014 to June 2015. A total of 706 (44.7%) children who had suffered from injuries were reported in the one year period. More male children (N?=?415, 58.7%) suffered injuries than females (N?=?291, 41.2%). The average out-of-pocket expenditure on treating an injury was US $24.1 [standard deviation (SD)?=?±$62.8] and mean school days lost were 25 days (SD?=?±51.8). Road traffic injuries (RTIs) resulted in higher costs [mean difference was US $51.1 (95% CI: $11.4–$90.8)] compared to injuries that, for example, occurred at school. In a Ugandan slum community, unintentional childhood injuries resulted in high out-of-pocket expenditures and missed school attendance. The costs varied widely depending on external causes of the injury. These findings highlight the need to invest in population level injury prevention interventions to reduce injury costs by households.     

Child motor vehicle occupant and pedestrian casualties before and after enactment of Child Restraint Seats Legislation in Japan

Problem. Prevention of injuries to child passengers is a significant public health priority, as motor vehicle-related injuries remain a leading cause of death for children in Japan. The purpose of compulsory child restraint seats legislation in April 2000 was to reduce the number of child passengers killed or injured in motor vehicle crashes.

Methods. The objectives of this preliminary evaluation are to measure the effectiveness, benefits and usage of safety seats for child passengers aged 1–5 years by analysing the child casualty data for the period of 1997–2002. Population and vehicle miles travelled based injury and fatality rates were used to compare before and after legislation trends in child casualties.

Results. Despite overall increases in the use of child restraint seats (as observed by different national surveys), overall casualty rates in motor vehicle occupants in the 1–5 year age group did not change (fatalities and serious injuries) or even increased (minor injuries).

Conclusions. Casualties among restrained children have not decreased since the law came to effect in the year 2000, perhaps because of incorrect usage of the seats. Given that exposure to crash environments is increasing, traffic safety advocates and public health community need to be aware of the importance of child restraints as a means of reducing the likelihood of injury. It is necessary to implement effective community-based child safety seat campaigns to disseminate the information on appropriate restraint use and to increase efforts to enforce the existing legislation.     

Epidemiologic features and intervention effect of fall injury among rural school-aged children in southwest China: a short-term cohort study

ABSTRACT

Falls are the top one type in all unintentional injuries. In this study, we aim to explore the epidemiological characteristics of falls and assess the intervention effect. Our research had interviewed 2854 rural children in southwest China. Then, we used School–Family–Individual (SFI) comprehensive education model to conduct an intervention among 1506 children and follow up them for one year. The changes in injury knowledge and incidence rate before and after intervention were compared. We found the fall injury was 37.32% (178/477) and ranked top one in the total injuries. After intervention, the children's fall-injuries-related knowledge was significantly increased by 15.29 percent (P < 0.001). While falls incidence significantly decreased after- intervention (6.24% vs. 3.93%; P < 0.001). From the results we concluded that the falls rate was high and was the prior reason of all injuries. SFI intervention model can effectively reduce the incidence of the fall injury.     

The burden of road traffic injuries in Kermanshah Province,Iran, in 2010–2011: GBD 2010 method

Deaths, injuries and disabilities resulting from road traffic injuries (RTIs) are a public health major concern. This study aims to calculate the burden of RTIs in Kermanshah Province in Iran. In this study to determine the years of life lost (YLL) related to RTIs, the National Death Registration and Forensics Medicine census data were employed. We use forensic medicine data to calculate the incidence of non-fatal injuries and years lost due to disability (YLD). The cause of death and non-fatal injuries was classified using ICD-10 codes and 23 groupes of global burden of diseases (GBD) 2010. The disability-adjusted life year (DALY) estimated on the guidelines of the GBD 2010 and age and sex structure was taken from the National Statistic Center for the year 2010. Overall, 70.8% of the subjects were males. The fatal and non-fatal injury rates of RTI were 51.3 and 283.6 per 100,000 persons, respectively. YLLs and YLDs were 46613 (24.5 per 1000) and 3405 (1.8 per 1000) in both sexes, respectively. The disability adjusted life years were 40711 in males, 9306 in females and 50018 in both sexes (42.5, 9.8 and 26.3 per 1000, respectively). More than 93% of DALY was from YLL (24.5 per 1000), with a small proportion for YLD (1.8 per 1000). Accounting for more than 50,000 DALY attributed to RTIs, traffic injuries is a major public health and socioeconomic problem in Kermanshah. Designing cost-effective interventions based on comprehensive and multi-sectoral programmes at the national and provincial levels can save many lives and resources that are lost every year. Undoubtedly, establishing a surveillance system at the sub-national level and measuring the burden of injuries, as in this study, can help policy-makers and planners in lessening the burden of RTIs.     

Indicators of injury burden: which types are the most important?

Injury indicators are used for monitoring the impact of injury prevention initiatives on the population burden of injury. The object of the present study was to identify the types of injury responsible for the major component of the population health burden of injury in a large cohort in Manitoba, Canada. Injury cases (ICD-9-CM 800-995) aged 18-64 years were identified from all Manitoba hospital data between 1988 and 1991. Morbidity data were obtained from hospital discharge abstracts 12 months prior to date of injury and for 12 months post-injury. Outcomes for individuals were calculated as the difference pre- and post-injury in hospital inpatient days. Death outcomes in the 12 months post-injury were obtained by linking the cohort with the population registry. Summed outcomes across the population were stratified into injury types based on the International Code of Diseases (ICD) code of the index injury. Outcomes were also stratified by injury severity score categories where the injury severity score was obtained using ICDMAP-90. When ranked by contribution to the cohort's cumulative hospital inpatient days in the 12 months post-injury, the six most common ICD subchapter groups accounted for 65% of the total inpatient days. These six injury types also accounted for 62% of the total number of deaths in this cohort in 12 months after injury. The suggested injury types to use as indicators of burden include fracture of the lower limb, fracture of the head and neck, poisonings, intracranial injury, fracture of the upper limb, and fracture of skull.     

Childhood and adolescent injuries in elementary schools in north-western Uganda: extent,risk and associated factors

Childhood injuries remain understudied in Uganda. The objective of this study was to determine the extent, nature and determinants of school-related childhood injury risk in north-western Uganda. A cohort of 1000 grade fives from 13 elementary schools was followed-up for one term. Survival and multi-level modelling techniques compared the risk rates across gender, schools and locations. Childhood injuries are common in north-western Uganda. Most of them occur during travel, breaks, practical classes and gardening, while walking, playing, learning and digging. Most injuries result from collisions with objects, sports and falls. Two-thirds of children receive first aid and hospital care. Times to injury were 72.1 and 192.9 person days (p = 0.0000). Gender differences in time to event were significant (p = 0.0091). Girls had better survival rates: cumulative prevalence of childhood injury was 36.1%; with significant gender differences (p = 0.007). Injury rate was 12.3/1000 person days, with a hazard ratio of 1.4. Compared to girls, boys had a 37% higher injury rate (p = 0.004). Rates varied among schools. Associated factors include sex and school. Rural–urban location and school differences do influence childhood injury risk. Childhood injuries are common: the risk is high, gender- and school-specific. Determinants include gender and school. Location and school contexts influence injury risk.     

Traffic death trends in children aged 0–14 years in Lithuania: patterns by age group

The aim of the study was to analyse traffic-injury mortality trends in children aged 0–14 years in Lithuania between 1971 and 2005. The data was derived from Statistics Lithuania. Trends were estimated by the use of cubic regression. In addition, data from ‘tail’ years was compared, and the t-test was used. The significance level p ≤0.05 was considered statistically significant. In the age groups 1–4 and 5–9 years, traffic injury mortality showed significantly decreasing trends, but in the age group 10–14 years, no significant tendencies have been observed. Traffic deaths as a proportion of injury deaths and as a proportion of all deaths have risen significantly in the age groups 1–4 and 10–14 years. In children aged 5–9 years, for traffic deaths percentage of injury deaths, no significance change was observed, and significant decrease was shown for traffic deaths percentage of all deaths. The study showed that in road safety work, more attention should be given to young adolescents aged 10–14 years and to children aged 1–4 years. A public health approach, effective law enforcements and community involvement are recommended for road safety management.     

Clothing-related motorcycle injuries in Pakistan: findings from a surveillance study

This study aims to assess the burden and patterns of clothing-related motorcycle injuries in Karachi, Pakistan. Data were extracted from an ongoing traffic injury surveillance system. In three years (2007–2009), out of 99155 road traffic injury cases there were 986 (0.9%) cases of clothing-related motorcycle injuries. Most cases were females (73.9%) and pillion riders (80.6%). The crashes involving clothing-related injuries were mostly single vehicle (98.5%), and largely resulted in injuries to the external body (60.3%), limbs (51.0%), head (41.5%) and face (35.9%). One-third of injuries were either moderate (26.7%) or severe (10.2%) while 10 (1.01%) deaths were reported. Female gender (11.4%), age ≥ 45 years (19.4%), pillion riding (11.3%) and crashes occurring at intersections (12.3%) were more likely to result in moderate or severe injury as compared to other users (P < 0.001). Injuries due to entanglement of loose fitting clothing in motorcycles are not uncommon in Karachi. Awareness campaigns for prevention of such injuries may involve promotion of appropriate dressing for motorcycle riding including close wrapping of clothes and encouraging installations of covers on the rear wheels and drive chains.     

Hospitalized fall-related injury trends in Sweden between 2001 and 2010

Previous studies have indicated increasing trends of hospitalized fall-related injuries amongst elderly. Whether this is true also in Sweden is unknown though it is important to study considering the potential societal impact. Data were obtained regarding hospitalized injuries with falls as external cause among those aged 65 years and above with information on injury type, gender and age, on a yearly basis, from 2001 to 2010. Age- and sex-specific incidence rates were calculated (per 100,000 population) for all fall-related injuries, and for each injury type and trend lines were drawn. Linear regression analyses and percentage change were calculated for the types of fall-related injuries. A decreasing incidence was observed in the younger age groups (65–79 years) with greater decreases amongst women (women: ?14.6%, men 65–79 years: ?10.5%). However, increasing rates were observed in the older age group (80 years and above), with greater increases amongst men (women: 4.3%, men: 11.4%). Superficial injuries showed greater increases than fractures amongst those aged 80 years and above. This study indicates that older elderly in Sweden are increasingly being hospitalized for less serious injuries. This changing injury panorama is important to include in the future planning of both health care and fall-related prevention.     

Injuries from Motorcycle- and Moped crashes in Sweden from 1987 to 1999

The objective of this paper is to study injuries from motorcycle and moped crashes in Sweden from 1987 to 1999. Databases at the National Board for Health and Welfare and codes from both ICD9 and ICD10 systems were used, including patterns of age, gender, E-code and type of injury. Length of hospital stay, type of injuries and trends over time was evaluated. To get a more detailed picture of the age distribution, type of vehicle used and number of killed, data from the Swedish National Road Administration were also used. In Sweden, 27,122 individuals received in-patient care due to motorcycle and moped injuries between 1987 and 1999. The motorcycle and moped injury rate was reduced in the second half of the studied period and so were the total days of treatment per year. Males had eight times the incidence of injuries compared to females. Riders under the age of 26 and in particular those at an age of 15 had the highest incidence rate. Head injuries were the most frequent diagnosis, followed by fractures to the lower limbs. Concussion was the most frequent head injury. Focal and diffuse brain injuries combined showed the same frequency as concussion. It is concluded that more preventative strategies must be presented before the injury rate can be reduced.     

A nationwide evidence-based study of factors associated with hospitalisations due to unintentional poisoning and poisoning mortality in Taiwan

The aim of this study was to explore the epidemiologic characteristics of unintentional poisoning cases and the factors associated with inpatient mortality. Data were retrieved from the National Health Insurance database from 2005 to 2007. Patients with diagnosis classifications of ICD-9-CM E850–E869 (unintentional poisoning) were selected. SPSS 18.0 software was used for the analysis. In Taiwan between 2005 and 2007, a total of 11,523 patients were hospitalised due to unintentional poisoning, with a hospitalisation rate of 16.83 per 100,000, of which 60.1% and 39.9% were attributable to drug poisoning and solid, liquid and gas substance poisoning, respectively. The hospitalisation rate in men was higher than that of women. The age group of 45–64 had the highest hospitalisation rate of 52.85 per 100,000. The inpatient mortality rate increased with the presence of the following factors: age of 65 or older, surgery or procedure, a higher Charlson Comorbidity Index (CCI), short length of hospital stays, acute respiratory failure, alcohol poisoning, pesticide poisoning and a higher-level hospital visited. Methanol, herbicides and organophosphorus pesticide intoxications are associated with higher mortality rates. Therefore, when caring for patients poisoned by the above agents, healthcare professionals should look out for their clinical development to ensure quality of care and to reduce mortality.
