EPIDEMIOLOGICAL STUDY OF INJURIES IN THE EMERGENCY DEPARTMENT OF THE UNIVERSITY HOSPITAL OF GEORGIA.

Injuries represent a significant burden on societies, resulting in deaths and health care costs incurred during Emergency Department visits and hospitalizations. This research aimed to estimate the burden of traumatic injury of patients treated and evaluated in the Emergency Department of the University Hospital in Georgia. A retrospective study was conducted at the University Hospital of Georgia for all trauma patients from January 1, 2018 to June 30, 2018. Visits were identified from existing electronic medical records, using the iCREATE Registry as a model. Data collected included patient demographics, injury characteristics, and injury costs. To estimate the direct costs of trauma treatment, data were obtained from the cost accounting database. A total of 2445 injured patients aged 0 to 91 years were medically examined during the study period and about 65% of them were male. Most of the injured patients were school-age children (31%). The leading mechanism of injury in the Emergency Departments were falls (45%). Most of the patients (78%) suffered from moderate injuries and needed only outpatient treatment. The total direct costs for all patients were $248 628. Fall-related injury costs accounted for most direct medical costs (51%), followed by road traffic crashes related costs (23%). Road traffic injured patients had the highest total mean costs ($269). Injuries result in a substantial number of Emergency Department visits and significant medical costs in Georgia. Understanding the characteristics of these injuries is essential for targeting injury prevention.

A RETROSPECTIVE STUDY OF THE MAXILLOFACIAL INJURIES IN TWO EMERGENCY DEPARTMENTS IN TBILISI, GEORGIA.

Maxillofacial injuries are a global problem in our modern society. It can be a major cause of increased morbidity and mortality. Maxillofacial trauma can lead to scar distortion accompanied by emotional and psychological problems. The epidemiology of facial fractures varies in terms of trauma type, the extent of injury, and severity. The main aim of this research is to explore the scope, the burden, and the etiology of maxillofacial injuries in Tbilisi, Georgia. Data was retrospectively collected from two large emergency departments in Tbilisi, Georgia using a cross-sectional design. Inclusion criteria was patients admitted in hospitals during one year with diagnosis maxillofacial injury. SPSS 21 software was used for statistical analysis. Differences in categorical variables were assessed with Chi-square tests of independence. This research shows that men are still the most frequent victims of maxillofacial injuries. Out of 598 patients, whose age ranged from 1month to 87 years - 67% were males, and 33% patients were females, including both, maxillofacial trauma alone and also combined injuries. With only maxillofacial injuries, the male patients were still leading, with 51% (307) and female patients were 28% (167), these results gave us a statistically significant difference (p=0.026). The main causes of maxillofacial injuries were falls, which equaled to 63% (378 patients) from total recorded data, as in many other countries. The results of this research provide really important information about future preventive interventions in the country. It also shows us that educating the public with prevention strategies is substantial.

Eye injury and demographic parameters associated with poor visual outcome.

BACKGROUND: Eye injuries can result in long-term disability, and healthcare providers need better tools to predict outcomes. Few prognostic models for poor visual acuity have been examined using variables usually present in very severe injuries, which creates a gap in prognosis. Therefore, a model associated with severe and less severe injuries is examined. METHODS: Eye injuries hospitalized in Bosnia and Herzegovina from 2006 through 2014 were included. A total of 258 eye injuries met the inclusion criteria of being an acute mechanical, chemical or physical eye injury. Prognostic variables were grouped by patient characteristics, eye injury characteristics and eye injury diagnosis. Poor final visual acuity was the main outcome measure (vision less than 20/200). Multivariable regression analysis used stepwise selection to identify the strongest set of predictive variables. RESULTS: Lens subluxation (95 % CI: 2.09-14.83), vitreous prolapse (95 % CI: 2.76-26.87), vitreous hemorrhage (95 % CI: 1.71-10.03), posterior segment intraocular foreign body (95 % CI: 1.19-39.09), and vitritis (95 % CI: 0.97-11.12) were significantly associated with poor final visual acuity. The predictive model identified the combination of age over 36, lens subluxation, vitreous prolapse and hemorrhage, vitritis, and macular hemorrhage as the combination most likely to have poor visual acuity. The final model resulted in a strong fit as measured by AIC, log likelihood, goodness-of-fit, and the c-statistic. CONCLUSIONS: This model can be used in clinical practice to evaluate the severity and predict final visual acuity in both severe and less severe eye injuries. The model accounts for characteristics of the injury as well as the patient. Additional studies with larger samples could further verify this model.

Characteristics of Fatal Agricultural Injuries by Production Type.

Although agriculture is recognized as a hazardous industry, it is unclear how fatal agricultural injuries differ by production type. The purpose of this study was to characterize fatal occupational injuries in agriculture, comparing crop and animal production, and determine which risk factors are specifically associated with each production type. A cross-sectional study was conducted among crop and animal pro ducers using data from the Census of Fatal Occupational Injuries in the Midwest region from 2005 to 2012. Rates offatal injury by production type were estimated. The frequency of fatal injury in each production type was also reported by demographic and injury characteristics. Finally, a logistic regression was performed to determine whether age, gender, injury timing, or injury event/exposure type were associated with crop or animal production. A total of 1,858 fatal agriculture-related injuries were identified, with 1,341 in crop production and 517 in animal production. The estimated rate of fatal injury was higher in crop production than in animal production (15.9 vs. 10.8 per 100,000 workers). Fatal injuries among young and elderly agricultural workers were significantly associated with crop production compared to animal production. Animal assaults, falls, and exposure to harmful substances or environments were significantly associated with animal production. Fatal agricultural injury is more common in crop production. However, the characteristics and risk factors of fatal injuries differ by production type. Intervention strategies may be guided by considering the production-specflc risk factors.

Factors influencing law enforcement decisions to adopt an evidence-based robbery prevention program.

Homicide is the leading cause of workplace death among small retail and service businesses in the United States. Evidence-based programs have been shown to reduce robbery and robbery-related crimes in small retail businesses; however, reaching small businesses with programs has been difficult. As small businesses typically have no corporate backing or trade affiliation, police departments have been identified as potential vehicles for program dissemination. A national sample of 300 law enforcement agencies was surveyed to identify facilitators and barriers to adoption and sustainability of an evidence-based program. The questionnaire was developed using behavioral theory concepts and administered via telephone. Preliminary findings suggest the primary facilitators to program adoption included organizational capacity factors such as staff buy-in, dedicated personnel and financial support. Competing responsibilities was the primary barrier identified by agencies. Agency size and program complexity were identified as potential predictors of program adoption. Identifying agency and program-specific characteristics that influence program adoption by law enforcement agencies will be valuable for marketing programs to agencies that have the infrastructure to support and sustain program dissemination. Understanding these factors will optimize the reach of evidence-based strategies to small businesses.

Economic sanctions, military activity, and road traffic crashes in Vojvodina, Serbia.

BACKGROUND: Political violence has not been examined as a risk factor for traumatic injuries from road traffic crashes. OBJECTIVE: To identify trends in road traffic crashes related to war-related military activity and international economic sanctions in the Autonomous Province of Vojvodina, Serbia. METHODS: Overall road traffic crashes and crashes leading to hospitalization and fatality in Vojvodina, Serbia were examined from 1996 through 2005. Rates were calculated per 100,000 population and per 10,000 registered vehicles. Three time periods were examined: years with international sanctions and military activity (1996-1999); years with international sanctions but no military activity (2000-2001); years with neither sanctions nor military activity (2002-2005). RESULTS: Compared with the period with neither sanctions nor military activity, severe injury crashes were 1.23 times more common (95% CI 1.19 to 1.27) during the period with sanctions and military activity and 1.21 times more common (95% CI 1.16 to 1.27) during the period with sanctions but no military activity. CONCLUSIONS: The data suggest that vehicle travel became safer after the end of military action and economic sanctions. Road traffic safety needs to be a priority during both periods of political unrest and its recovery phase.

Hospitalisations for sport-related concussions in US children aged 5 to 18 years during 2000-2004.

OBJECTIVES: To describe patient and hospital characteristics associated with hospitalisation for a diagnosis of non-fatal sport-related concussion, and to determine factors associated with these hospitalisations. METHODS: Children aged 5-18 years with a primary diagnosis of a sport-related concussion in the Nationwide Inpatient Sample (2000-2004) were identified. Length of stay and hospital charges for sport-related concussions were documented. Logistic regression was used to assess the association of patient or hospital characteristics with hospitalisations for sport-related concussion. RESULTS: Between 2000 and 2004, a total of 755 non-fatal paediatric sport-related hospitalisations for concussion were identified. Nationwide, this represents 3712 hospitalisations and over US$29 million total hospital charges, with nearly US$6 million in total hospital charges per year. Over half (52.3%) of patients with concussion experienced loss of consciousness. Over 80% of the patients hospitalised for concussion received no procedures during their average 1.1 day (median 0.8 day) of hospital stay. Older age, but not gender, was associated with increased odds of sport-related hospitalisations for concussion. Non-teaching hospitals or hospitals in rural areas had significantly greater odds of admitting sport-related concussions versus other sport-related traumatic brain injuries compared with teaching or urban hospitals. CONCLUSIONS: Management of paediatric sport-related concussions varied, depending on the patient and the hospital. Better guidelines are needed for the identification and management of sport-related concussions. Standardised procedures for hospitals treating concussive injuries may also be warranted.

Police deaths in New York and London during the twentieth century.

OBJECTIVES: To describe the incidences and causes of occupational police deaths in New York City in the United States and Greater London in the United Kingdom during the twentieth century. To assess the relation between overall societal violence and violence directed toward police officers in these metropolitan areas. DESIGN AND SETTING: Ecological study of New York and London from 1900 through 1999. MAIN OUTCOME MEASURES: Intentional and unintentional occupational police mortality rates for New York and London were estimated for each decade. The general population homicide rates of both New York and London were assessed for their correlation with their respective intentional occupational police mortality rates. RESULTS: During the 20th century, 585 police officers in New York and 160 police officers in London died while participating in law enforcement activities. New York had markedly greater intentional police mortality rates compared to London throughout most of the 20th century, but these differences decreased significantly by the end of the century. Intentional gunshot wounds comprised 290 police deaths in New York, but only 14 police deaths in London. In New York, gun shot wounds (both intentional and unintentional) accounted for more occupational police deaths (51.6%) than did all other injury mechanisms combined. In London, motor vehicle collision was the most common cause (47.5%) of occupational police death. There were no apparent correlations between the general population homicide rates and intentional police mortality rates in either New York (r(2) = 0.05, 95% CI -0.77 to 0.81) or London (r(2) = 0.34, 95% CI -0.61 to 0.89). CONCLUSIONS: During the 20th century, both intentional and unintentional occupational police mortality rates were significantly greater in New York compared to London. These differences are likely from several socioeconomic, cultural, and occupational factors. The declines in police deaths in New York during the latter part of the 20th century indicate that at least some measures taken by the New York Police Department have been successful at significantly reducing the incidence of both intentional and unintentional police deaths.

Depressive symptoms as a risk factor for unintentional injury: a cohort study in a rural county.

OBJECTIVE: The authors used data from a population based prospective cohort study to determine if depressive symptoms predicted incidence of unintentional injury. METHODS: The Keokuk County Rural Health Study, based in Iowa, is a prospective cohort study of health status that includes injury outcomes. Depressive symptoms were measured using the 11-item Center for Epidemiologic Studies Depression Scale at the beginning of the study on 1493 participants. Quarterly follow up phone calls were made to measure injury incidence. RESULTS: 471 injuries were reported for an overall injury rate of 9.8 per 100 person-years. Crude injury rates were significantly higher for those with depressive symptoms (p = 0.0003). Those with depressive symptoms had a 41% increased risk for injury after controlling for antidepressant medication use, gender, prior injury, income, and sleepiness (RR = 1.41, 95% CI 1.10 to 1.80). Depressive symptoms remained a risk factor for injury regardless of current antidepressant medication use (no medication use, RR = 1.43, 95% CI 1.09 to 1.88; medication use, RR = 1.31, 95% CI 0.76 to 2.26). CONCLUSIONS: Depressive symptoms were found to be risk factors for unintentional injury. Medical practitioners should consider talking about safety with their patients, especially those reporting symptoms of depression, and recognize that an increased risk for injury remains until the depressive symptoms subside.

When one is not enough: prevalence and characteristics of homes not adequately protected by smoke alarms.

OBJECTIVE: The National Fire Protection Association (NFPA) has specific recommendations about the number, location, and type of smoke alarms that are needed to provide maximum protection for a household. No previous studies have examined whether or not homes are completely protected according to these guidelines. The authors describe the prevalence and home characteristics associated with compliance to recommendations for smoke alarm installation by the NFPA. DESIGN, SETTING, AND SUBJECTS: Data are from the baseline on-site survey of a randomized trial to measure smoke alarm effectiveness. The trial was housed in a longitudinal cohort study in a rural Iowa county. Of 1005 homes invited, 691 (68.8%) participated. MAIN OUTCOME MEASURES: Information about smoke alarm type, placement, and function, as well as home and occupant characteristics, was collected through an on-site household survey. RESULTS: Although 86.0% of homes had at least one smoke alarm, only 22.3% of homes (approximately one in five) were adequately protected according to NFPA guidelines. Fourteen percent of homes had no functioning smoke alarms. More than half of the homes with smoke alarms did not have enough of them or had installed them incorrectly, and 42.4% of homes with alarms had at least one alarm that did not operate. Homes with at least one high school graduate were nearly four times more likely to be fully protected. Homes that had multiple levels, a basement, or were cluttered or poorly cleaned were significantly less likely to be fully protected. CONCLUSION: These findings indicate that consumers may not be knowledgeable about the number of alarms they need or how to properly install them. Occupants are also not adequately maintaining the alarms that are installed.

A population based study of reporting patterns and characteristics of men who abuse their female partners.

OBJECTIVE: This study estimates the prevalence of male abusive behavior reported by men and their female partners and identifies characteristics of abusive men. DESIGN: Baseline survey from a population based cohort study of general health. SETTING: A rural county in Iowa, USA. SUBJECTS: 572 men and their cohabitating female partners. MAIN OUTCOME MEASURES: Male-to-female physical, emotional, and sexual abuse reported by either partner. RESULTS: In this cohort, 13.6% of men had performed at least one act of physical abuse and 34.9% emotional abuse. More than 45% of abusive men reported their own behaviors. Alcohol problems, antisocial personality characteristics, depressive symptoms, and financial stress were all positively associated with both physical and emotional abuse, but suicidal thoughts were less likely among abusers. CONCLUSION: Identification of common characteristics of abusive men may predict proclivity towards partner violence and barriers to behavior modification.

Fatal motor vehicle crashes in rural and urban areas: decomposing rates into contributing factors.

OBJECTIVES: Motor vehicle crash fatality rates have been consistently higher in rural areas than in urban areas. However, the explanations for these differences are less clear. In this study the decomposition method was used to explore the factors associated with increased fatal crash involvement rates in rural communities. DESIGN: Using national databases, the fatal crash incidence density was decomposed into the product of three factors: the injury fatality rate, the crash injury rate, and the crash incidence density. RESULTS: As expected, the fatal crash incidence density was more than two times higher in rural than in urban areas. This was driven primarily by the injury fatality rate, which was almost three times higher in rural areas. CONCLUSIONS: Further research should examine the relative roles of crash severity and the timely receipt of definitive medical care after a crash.

Disability and risk of school related injury.

OBJECTIVE: Approximately six million children with disabilities attend school in the United States. Cognitive and physical limitations may compromise their ability to handle environmental hazards and hence increase their risk for injury. The objective of this study was to describe the epidemiology of school related injury among children enrolled in 17 special education schools in one large, urban school district. DESIGN: Altogether 6769 schoolchildren with disabilities were followed up from 1994-98. Injury and population data were collected from pupil accident reports and existing school records. Associations were estimated through generalized estimating equations. RESULTS: A total of 697 injuries were reported for a rate of 4.7/100 students per year. Children with multiple disabilities had a 70% increased odds of injury compared with the developmentally disabled (odds ratio (OR) 1.7, 95% confidence interval (CI) 1.3 to 2.3). The physically disabled (OR 1.4, 95% CI 1.0 to 1.9) had a modest increased odds of injury. Cuts, bruises, and abrasions composed almost three fourths of all injuries; almost half of these injuries were to the face. Falls (34%) and insults by other students (31%) were the most common external causes. More than a fourth of injuries were sports related, and 21% occurred on the playground/athletic field. Injury patterns differed across disabilities. CONCLUSIONS: Although limited to one school district, the population studied is the largest cohort thus far of schoolchildren with disabilities. With this large study base, potentially high risk groups were identified and circumstances of injury described. This information is imperative for developing and improving school based injury prevention measures.

Nighttime driving, passenger transport, and injury crash rates of young drivers.

OBJECTIVE: This study examines the association of nighttime driving and the carrying of passengers with the rate of motor vehicle crashes that resulted in severe or fatal injury to young drivers in California before the implementation of a graduated licensing system. METHOD: Passenger vehicle drivers aged 16 or 17 involved in injury crashes in California from 1 January 1993 to 30 June 1998 were identified through a police crash database. An induced exposure method was used to estimate driving exposure. Odds ratios for driver injury crashes were estimated with logistic regression. RESULTS: Driving at night, driving without adult supervision, driving with passengers, using alcohol, being 16, and being male were associated with high rates of driver injury crash. CONCLUSIONS: The injury crash rate for drivers aged 16 or 17 increases during nighttime hours and in the absence of adult supervision, with or without other passengers. Driving between 10 pm and midnight is particularly dangerous for young drivers. Nighttime driving restrictions that begin at 10 pm or earlier and restrictions on carrying passengers at any hour may increase the effectiveness of graduated licensing systems.

Seismic, structural, and individual factors associated with earthquake related injury.

BACKGROUND: Earthquakes cause thousands of deaths worldwide every year, and systematic study of the causes of these deaths can lead to their prevention. Few studies have examined how multiple types of risk factors are related to physical injury during an earthquake. METHODS: A population based case-control study was conducted to examine how individual characteristics, building characteristics, and seismic features of the 1994 Northridge, California, earthquake contributed to physical injury. Cases included fatal and hospital-admitted injuries caused by the earthquake. Controls were drawn from a population based phone survey of county residents. Cases were individually matched to two sets of controls: one matched by age and gender and one matched by location at the time of the earthquake. RESULTS: Individuals over age 65 had 2.9 times the risk of injury as younger people (95% confidence interval (CI) 1.2 to 7.4) and women had a 2.4 times greater risk than men (95% CI 1.2 to 5.1). Location in multiple unit residential and commercial structures each led to increased injury risk compared with single unit residential structures, but the exact estimate varied depending on the control group used. With every increase in ground motion of 10%g, injury risk increased 2.2 times (95% CI 1.6 to 3.3). CONCLUSIONS: Controlling for other factors, it was found that individual, building, and seismic characteristics were independently predictive of increased injury risk. Prevention and preparedness efforts should focus on each of these as potential points of intervention.

Local television news coverage of traumatic deaths and injuries.

OBJECTIVE: To assess how local television news programs' reporting of injuries and deaths from traumatic causes compares with coroners' records of deaths and the estimated incidence of injuries in the same geographic area during the same time. METHODS: Using epidemiologic methods, we identified the underlying cause of death or injury in each of 828 local television news stories broadcast in Los Angeles during late 1996 or early 1997 that concerned recent (<3 days) traumatic injuries or deaths in Los Angeles County. Odds ratios were computed using deaths by homicide or injuries sustained in assaults as the referent group. RESULTS: The number of persons depicted as dead amounted to 47.8% of the actual total number of traumatic deaths occurring in Los Angeles County during the study period. In contrast, the number depicted as injured represented only 3.4% of injuries due to traumatic causes. Both injuries and deaths due to fires, homicides, and legal interventions were proportionally well represented. However, injuries and deaths from accidental poisoning, falls, and suicide were significantly underrepresented. CONCLUSIONS: Some types of events receive disproportionately more news coverage than others. Local television news tends strongly to present only those events concerned with death or injury that are visually compelling. We discuss reasons for concern about the effect that this form of information bias has on public understanding of health issues and possible counteractions that physicians can take.

Early predictors of mortality in penetrating compared with closed brain injury.

INTRODUCTION: Although brain injury incidence rates have been decreasing, the proportion of these injuries which are penetrating has been increasing. This study compares mortality amongst persons with penetrating and closed brain injuries and explores the relationship of early predictors of mortality. METHODS: The study included 795 moderately or severely brain injured individuals identified through the UCLA Brain Injury Research Centre. Logistic regression was used to predict mortality by GCS level and brain injury type, controlling for age, gender, and presence of multiple trauma. RESULTS: Of the 795 individuals, 110 had penetrating and 685 had closed brain injury. Case fatality rates were higher for penetrating than closed injuries for all GCS, gender, age, and cause of injury categories. When controlling for GCS level at admission, age, gender, and multiple trauma, those with penetrating injuries were 6.6 (95% CI = 3.9-11.1) times more likely to die. CONCLUSIONS: As the pool of information about survival and recovery from penetrating injuries grows, decisions regarding clinical care and prevention activities can be more appropriately focused.

A geographic analysis of motor vehicle collisions with child pedestrians in Long Beach, California: comparing intersection and midblock incident locations.

OBJECTIVES: The purpose of this study was to use geographic information system (GIS) software to locate areas of high risk for child pedestrian-motor vehicle collisions in the city of Long Beach and to compare risk factors between midblock and intersection collisions. METHODS: Children 0-14 years of age involved in a motor vehicle versus pedestrian collision that occurred on public roadways in Long Beach, CA, between 1 January 1992 and 30 June 1995, were identified retrospectively from police reports. The GIS software program, ArcView, was used for spatial analysis and distance calculations. chi2 Tests were used to compare the distribution of the characteristics between intersection and midblock collisions. RESULTS: The average annual incident and fatality rate was 183.3/100,000 children/ year and 2.4/100,000 children/year, respectively. Children less than 5 years of age were significantly more likely to be hit at a midblock location while those aged 5-9 and 10-14 were more often hit at an intersection. Intersection collisions were more likely to occur on major arterials and local streets, and the driver to be the primary party at fault (p<0.001). While intersection incidents tended to occur further from the child's home (64.4%) the majority of midblock incidents (61.5%) occurred within 0.1 miles of the child's residence. For both midblock and intersection locations, pedestrian collisions tended to occur more frequently in those census tracts with a larger number of families per census tract-a measure of household crowding and density. CONCLUSIONS: Future studies taking into consideration traffic volume and vehicle speed would be useful to focus prevention efforts such as environmental modifications, improving police enforcement, and educational efforts targeted at parents of younger children. As GIS illustrative spatial relationships continue to improve, relationships between pedestrian collision sites and other city landmarks can advance the study of pedestrian incidents.
