Falls from a balcony while intoxicated: a new injury trend among young adults?

BACKGROUND: Unintentional falls from heights, including balconies, result in life threatening traumatic injury. Alcohol, when combined with environmental factors and poor judgement, can potentially lead to fatal outcomes. One trauma center's registry identified a group of young adults falling from balconies and we investigated the role of alcohol. METHODS: Hospital trauma service admissions from 2010 through 2017 were reviewed for unintentional falls from heights. Suicide attempts and unintentional falls off ladders or roofs were excluded. Data were obtained from trauma registry and medical record review, as well as social work service interviews. RESULTS: Falls from heights comprised 4.8% of injuries treated at our trauma center during the eight-year study period with 98.5% admitted. Of patients admitted because of falls, 10.3% (55/532) were from a balcony. The majority of this group of patients was male and 19-29 years old (67%). Of patients with a blood alcohol concentration (BAC) determination, 62% had a positive BAC upon hospital admission with an average of 0.20 g/dL among those 34 patients. No gender differences were evident for alcohol use. Seven of the eight patients under the legal drinking age of 21 years were a subgroup with high alcohol use as compared with patients 21 years and older (p = 0.099). Ninety-four percent of falls occurred at residential locations such as dormitories or apartment complexes, often during a social event. Backward falls off railings and attempts to jump to adjoining balconies were common. Head, thorax/abdomen, and extremity fractures were common, with an average injury severity score (ISS) of 16. Average length of hospital stay was 8 days. Most patients (67%) were discharged home after hospital stay, but 21% were transferred to inpatient rehabilitation or skilled nursing facilities. There were two deaths. CONCLUSIONS: Falls from balconies among young adults occur in our area yet the true frequency of these events remain unknown. Occurrence was most common among underage drinkers. Generalization is difficult with this small sample, yet high risk behaviors and environmental factors were evident. It is imperative that educational programs focus on this population with collaborative prevention efforts focused on the dangers of, and increased risk of injury associated with the balcony environment.

Trauma resource designation: an innovative approach to improving trauma system overtriage.

BACKGROUND: Effective triage of injured patients is often a balancing act for trauma systems. As healthcare reimbursements continue to decline,1 innovative programs to effectively use hospital resources are essential in maintaining a viable trauma system. The objective of this pilot intervention was to evaluate a new triage model using 'trauma resource' (TR) as a new category in our existing Tiered Trauma Team Activation (TA) approach with hopes of decreasing charges without adversely affecting patient outcome. METHODS: Patients at one Level II Trauma Center (TC) over seven months were studied. Patients not meeting American College of Surgeons criteria for TA were assigned as TR and transported to a designated TC for expedited emergency department (ED) evaluation. Such patients were immediately assessed by a trauma nurse, ED nurse, and board-certified ED physician. Diagnostic studies were ordered, and the trauma surgeon (TS) was consulted as needed. Demographics, injury mechanism, time to physician evaluation, time to CT scan, time to disposition, hospital length of stay (LOS), and in-hospital mortality were analyzed. RESULTS: Fifty-two of the 318 TR patients were admitted by the TS and were similar to TA patients (N=684) with regard to gender, mean Injury Severity Score, mean LOS and in-hospital mortality, but were older (60.4 vs 47.2 years, p<0.0001) and often involved in a fall injury (52% vs 35%, p=0.0170). TR patients had increased door to physician evaluation times (11.5 vs 0.4 minutes, p<0.0001) and increased door to CT times (76.2 vs 25.9 minutes, p<0.0001). Of the 313 TR patients, 52 incurred charges totaling US$253 708 compared with US$1 041 612 if patients had been classified as TA. CONCLUSIONS: Designating patients as TR prehospital with expedited evaluation by an ED physician and early TS consultation resulted in reduced use of resources and lower hospital charges without increase in LOS, time to disposition or in-hospital mortality. LEVEL OF EVIDENCE: Level II.

Head injuries in hospital-admitted adolescents and adults with skateboard-related trauma.

OBJECTIVE: To provide new information on properties of skateboarders who were hospital admitted with head injuries with details of the injuries including region of head impact. METHODS: Hospital records of patients aged 15 and older with a skateboard injury admitted to one Level II Trauma Centre during a 10-year period were reviewed. Data on demographic, exposure, severity, diagnostic and clinical factors for patients with head injury (HI) and without HI (N-HI) were compared analytically. RESULTS: While there were no differences for patients with HI and N-HI by age, gender, mechanism of injury or alcohol use, patients with HI were more severely injured. Although significantly more head impacts occurred to the occipital region of the head, haematomas and/or contusions were much more likely to occur in the frontal region of the brain. Acute neurosurgical intervention was needed in 14% of HI skateboarders. CONCLUSION: Skateboarding is not an innocuous recreational activity, with head injury present in 75% of patients who were hospital-admitted. Pre-hospital treatment protocols should be aware of this growing injured population. Falls while on a skateboard lead to impacts to the back of head with a contra-coup brain injury resulting in severe and sometimes fatal outcomes. The very low prevalence of helmet use among skateboarders with head injuries indicates that greater efforts should be directed toward incentives for their use.

Sustained outcomes following mild traumatic brain injury: results of a five-emergency department longitudinal study.

OBJECTIVE: To report on the occurrence of sustained outcomes including post-concussion symptoms, health services used and indicators of social disruption following a mild traumatic brain injury (MTBI). RESEARCH DESIGN: A dual cohort comparing MTBI Emergency Department (ED) patients and a comparison group of non-head injured ED patients. METHODS AND PROCEDURES: The outcomes measures employed were the Rivermead Post-Concussion Symptoms Questionnaire (RPQ) and indicators of health services used and social disruption all recorded at the ED and at 3 and 6 months post-ED discharge. 'Sustained' meant a positive response to these measures at 3 and 6 months. MAIN OUTCOMES AND RESULTS: Reasonable follow-up success was achieved at 3 and 6 months and the cohorts were alike on all demographic descriptors. RPQ average score and symptom occurrence were far more frequent among MTBI patients than for the comparison cohort from 3 to 6 months. The use of health services and indicators of social disruption were also more frequent among MTBI post-discharge patients. CONCLUSIONS: These findings argue that some with an MTBI suffer real complaints and they are sustained from 3 to at least 6 months. More effort should be given toward specificity of these symptoms from those reported by members of the comparison group.

A journey to and through injury epidemiology.

This brief commentary describes key events in the development of Dr. Jess Kraus's professional career in injury epidemiology from the 1950s to the 2000s. It highlights the interactions with Dr. William Haddon Jr. and other researchers that were instrumental to his contributions to the field of injury epidemiology.

Epidemiological and clinical features of an older high-risk population of skateboarders.

BACKGROUND: Skateboard injuries have been described in the media and scientific journals as a problem prevalent among children and adolescents. Skateboarding popularity has continued to grow since the 1970s with ridership increasing to include all age groups. Recently, surgeons at one trauma centre at an urban hospital noted an increase in the number of older skateboarders with life-threatening injuries. We hypothesise that the clinical and epidemiological features of skateboard-related injuries from one trauma centre (TC) will be different from injured skateboarders identified in the U.S. National Trauma Data Bank (NTDB). We also sought to identify factors related to poor outcomes in the TC and NTDB patient groups. METHODS: Two injured skateboarder patient groups were identified and compared using proportional morbidity odds ratios (PMORs) and multivariable methods to estimate differences among factors common to both groups of patients. Clinical and demographic features were evaluated for hospital admitted patients injured whilst riding a skateboard. Chi-square tests, PMORs and logistic regression were used to determine outcome differences between patients in both groups. RESULTS: Patients in the TC group were on average older, with higher Injury Severity Scores (ISS), more head injuries requiring neurosurgical intervention, longer ICU and hospital stays, and injured more frequently on local streets than patients in the NTDB series. Poor outcomes in the TC group were related to moderate or severe head injuries and presence of a head/face injury. For NTDB patients, a GCS of <13, a head/face injury and an ISS of 25+ were related to poor outcomes. CONCLUSIONS: From our Trauma Centre we describe an older injured skateboarding population, clinically and epidemiologically different from injured patients identified in the NTDB as well as those described in the literature. The greater severity of injury, including traumatic brain injury, has direct implications for preventive and educational measures and the planning of emergency surgical response.

Media literacy as a violence-prevention strategy: a pilot evaluation.

Youth violence is a major unresolved public health problem in the United States and media exposure to violence is a synergistic source of this national problem. One media literacy curriculum designed specifically to address this issue is Beyond Blame: Challenging Violence in the Media. The purpose of this pilot study was to examine the curriculum's feasibility as a full-scale intervention. Intervention and control groups were similar with respect to knowledge of the Beyond Blame curriculum at baseline. Intervention students scored much higher on the posttest compared with the control students. The majority (90.2%) of the intervention students reported a significant increase in pre- to posttest score compared with only 18.8% of the control students (p < .0001). The magnitude of the score increase for intervention students was much greater than those in the control group. Several intervention students (N = 49; 19.9%) improved their score by 12 or more points compared with the control students who showed only a 1- to 7-point score increase (N = 3; 18.8%; p < .0001). The pre-and posttest scores were similar for males and females. Three of the six intervention classrooms scored higher on both the pretest and posttest compared with the other three classrooms.

Preinjury factors and 3-month outcomes following emergency department diagnosis of mild traumatic brain injury.

OBJECTIVE: To investigate the sequelae of mild traumatic brain injury (MTBI) by comparing selected outcomes of emergency department-diagnosed patients with mild head injuries to those with non-head injuries. SETTING: Five emergency departments in southern California. PARTICIPANTS: Two cohorts, one with MTBI (n = 689 at initial assessment) and another with non-head injuries (n = 1318). MAIN MEASURES: Rivermead Post-Concussion Symptoms Questionnaire and Pittsburgh Sleep Quality Index at 3 months postinjury. RESULTS: Postconcussion symptom rates and summary Rivermead Post-Concussion Symptoms Questionnaire scores were significantly higher for persons with MTBI than for the comparison cohort. Women reported significantly more symptoms than men. Complaints about sleep quality overall (and also sleep latency and daytime dysfunction subcomponents) were significantly more frequent among those with MTBI. CONCLUSION: Patients with MTBI have significantly more negative outcomes than patients in the comparison cohort and should be clinically managed with these prevalent outcomes in mind. Further study of follow-up medical management and the development of treatment guidelines for this group of patients are both warranted.

Immunologic function after splenic embolization, is there a difference?

BACKGROUND: To define the immunologic status of patients undergoing splenic embolization (SE) after traumatic injury. This information may lead to the development of immunization protocols based on scientific data. METHODS: Patients with traumatic splenic injury, treated at one level II Trauma Center were eligible for study. SE patients were compared with splenectomy (SP) patients and controls (C = blunt abdominal trauma patients with negative abdominal computed tomography scans). Clinical examination, medical survey, blood sampling, and nuclear medicine spleen scans were performed. IgM, IgG, C3 complement, complement factor B, helper T cells (CD3, CD4), suppressor T-cells (CD8), complete blood counts, and HIV status were tested. Radionuclide spleen scans were analyzed for total spleen volume, splenic defects, abnormal radionuclide uptake, and ectopic sites of tracer uptake. RESULTS: There were no significant differences in age, gender, or injury severity score among groups. Follow-up time was comparable (SP = 2.67 years; SE = 2.88 years). There were no significant differences in all studies measured except for higher CD8 levels in the SP group (730.1 vs. SE 452.1 vs. C 480.6; p = 0.002), although all values were within the normal range. CD3 levels showed a trend of being higher in the SP group (1709.3 vs. SE 1397.2 vs. C 1371.9), but were not statistically significant. CONCLUSION: The data suggest that the immunologic profile of embolized patients is similar to controls. This supports the safe use of SE in managing the traumatically injured spleen. Larger studies examining the immune function after SE will be needed to make definitive vaccination recommendations.

A review of risk factors and patterns of motorcycle injuries.

Per vehicle mile traveled, motorcycle riders have a 34-fold higher risk of death in a crash than people driving other types of motor vehicles. While lower-extremity injuries most commonly occur in all motorcycle crashes, head injuries are most frequent in fatal crashes. Helmets and helmet use laws have been shown to be effective in reducing head injuries and deaths from motorcycle crashes. Alcohol is the major contributing factor to fatal crashes. Enforcement of legal limits on the blood alcohol concentration is effective in reducing motorcycle deaths, while some alcohol-related interventions such as a minimal legal drinking age, increased alcohol excise taxes, and responsible beverage service specifically for motorcycle riders have not been examined. Other modifiable protective or risk factors comprise inexperience and driver training, conspicuity and daytime headlight laws, motorcycle licensure and ownership, riding speed, and risk-taking behaviors. Features of motorcycle use and potentially effective prevention programs for motorcycle crash injuries in developing countries are discussed. Finally, recommendations for future motorcycle-injury research are made.

A study of the effectiveness of a workplace violence intervention for small retail and service establishments.

OBJECTIVE: Examine the effectiveness of a robbery and violence prevention program in small businesses in Los Angeles. METHODS: Gas/convenience, liquor and grocery stores, bars/restaurants, and motels were enrolled between 1997 and 2000. Intervention businesses (n = 305) were provided training, program implementation materials, and recommendations for a comprehensive security program. Control businesses (n = 96) received neither training nor program materials. RESULTS: Rate ratios comparing intervention to control businesses were 0.90 for violent crime (95% confidence limits [CL] = 0.53, 1.53) and 0.81 for robbery (95% CL = 0.38, 1.73). The reduction in violent crime was concentrated in high-compliance intervention businesses (risk ratio = 0.74, 95% CL = 0.40, 1.36). Low-compliance intervention businesses had practically the same postintervention crime as the control businesses. CONCLUSIONS: Our results suggest that the workplace violence intervention may reduce violent crime among high-risk businesses, especially those with high program compliance.

Methodological issues in motorcycle injury epidemiology.

Motorcycle riders are over 30 times more likely than car occupants to die in a traffic crash. While this fact is well known, specific issues of methodology in epidemiological motorcycle-injury research have been rarely researched. To facilitate more-valid research on motorcycle injuries, this article evaluates the current state of our knowledge on how we measure the population at risk of injury, completeness of case finding and identification, validity of crash/injury data sources, and completeness of information on important exposures such as alcohol consumption, helmet status, crash severity, and crash speeds, as well as problems of existing injury severity scales and statistical analyses for correlated injury data.

Violent entertainment pitched to adolescents: an analysis of PG-13 films.

OBJECTIVE: The purpose of this study was to evaluate the violence content of the top-grossing PG-13 films of 1999 and 2000 to determine what percentage of it had potential for negative effects on young viewers and what percentage of it had potential for prosocial or beneficial effects. METHODS: A large, multidimensional analytic instrument was designed for systematic coding of each act of violence and its contextualization by features that have been shown either to enhance or to protect against harmful effects that are associated with violent media exposure: perpetrators and victims of violence, motivation for violence, presence of weapons, degree of realism, and consequences of violence. Descriptive statistics by genre were performed for each film. An ordinal logistic regression model was used to examine the association between the seriousness of violence and weapons, motive, and genre. RESULTS: In the sample of 77 PG-13 films, a total of 2251 violent actions were observed with roughly half (47%) of lethal magnitude. A total of 118 acts contained justified violence that were initiated by major characters and were extremely serious, and approximately two thirds of the films (49 [64%]) were rated PG-13 for reasons other than violence. CONCLUSIONS: Violence permeated nearly 90% of the films in our study. Although only a small subset of this content contained violence that was associated with negative effects, only 1 film contained violence that was associated with protective or beneficial effects.

The effectiveness of video-telemedicine for screening of patients requesting emergency air medical transport (EAMT).

BACKGROUND: Demand for emergency air medical transport (EAMT) services have increased in recent years. However, the high costs of these services have raised questions on the benefit to patient outcomes. In this study, we evaluate the effectiveness of video-telemedicine for the preflight screening of patients for air medical transports. METHOD: A prospective cohort study. Medical records of patients transported from the Penghu Islands to Taiwan were retrospectively collected from November 1999 to October 2002 (stage 1). In addition, we collected medical records of patients who were preflight-screened by physicians using video Web cameras from November 1, 2002 through August 30, 2003 (stage 2). The intervention in stage 2 included a set of protocols and screening criteria for EAMT implemented by the National Aeromedical Consultation Center (NACC). In stage 1, there were no standardized protocols or screening guidelines for EAMT. The EAMT system before implementing preflight screening and telemedicine was mostly based on patient's requests and their health condition determined by the treating medical officers (TMO). RESULTS: A total of 822 transfers were included in this study. Patient demographic backgrounds in the two groups were similar on gender, age, disease classification, and types of illnesses. Patients in stage 2 were significantly older than those in stage 1. In a comparison of flight frequencies between the two stages, the results revealed a 36.2% reduction of EAMT applications in stage 2. The flight approval rate was 91.2%. The intervention in stage 2 also presented a significant reduction in cross-zone transport (16.1% to 0.1% to the northern Taiwan region). Within-zone transfers increased from 74.9% to 88.3%. Cost analysis showed that physician triage in stage 2 resulted in a total annual savings on EAMTs of US 448,986 dollars. CONCLUSIONS: This study demonstrates the physician-assisted preflight screening using video-telemedicine significantly reduced the frequency of unnecessary air medical transports and consequently led to reduced costs. Video-telemedicine can be an essential tool to support physicians in decision-making for patient screening.

Guidelines for the pharmacologic treatment of neurobehavioral sequelae of traumatic brain injury.

There is currently a lack of evidence-based guidelines to guide the pharmacological treatment of neurobehavioral problems that commonly occur after traumatic brain injury (TBI). It was our objective to review the current literature on the pharmacological treatment of neurobehavioral problems after traumatic brain injury in three key areas: aggression, cognitive disorders, and affective disorders/anxiety/ psychosis. Three panels of leading researchers in the field of brain injury were formed to review the current literature on pharmacological treatment for TBI sequelae in the topic areas of affective/anxiety/ psychotic disorders, cognitive disorders, and aggression. A comprehensive Medline literature search was performed by each group to establish the groups of pertinent articles. Additional articles were obtained from bibliography searches of the primary articles. Group members then independently reviewed the articles and established a consensus rating. Despite reviewing a significant number of studies on drug treatment of neurobehavioral sequelae after TBI, the quality of evidence did not support any treatment standards and few guidelines due to a number of recurrent methodological problems. Guidelines were established for the use of methylphenidate in the treatment of deficits in attention and speed of information processing, as well as for the use of beta-blockers for the treatment of aggression following TBI. Options were recommended in the treatment of depression, bipolar disorder/mania, psychosis, aggression, general cognitive functions, and deficits in attention, speed of processing, and memory after TBI. The evidence-based guidelines and options established by this working group may help to guide the pharmacological treatment of the person experiencing neurobehavioral sequelae following TBI. There is a clear need for well-designed randomized controlled trials in the treatment of these common problems after TBI in order to establish definitive treatment standards for this patient population.

Employee and customer injury during violent crimes in retail and service businesses.

OBJECTIVES: We sought to compare the frequency and risk factors for employees and customers injured during crimes in retail (convenience, grocery, and liquor stores) and service businesses (bars, restaurants, motels). METHODS: A total of 827 retail and service businesses in Los Angeles were randomly selected. Police crime reports (n=2029) from violent crimes that occurred in these businesses from January 1996 through June 2001 were individually reviewed to determine whether a customer or an employee was injured and to collect study variables. RESULTS: A customer injury was 31% more likely (95% confidence interval [CI]=1.11, 1.51) than an employee injury during a violent crime. Customer injury was more frequent than employee injury during violent crimes in bars, restaurants, convenience stores, and motels but less likely in grocery or liquor stores. Injury risk was increased for both employees and customers when resisting the perpetrator and when the perpetrator was suspected of using alcohol. Customers had an increased risk for injury during crimes that occurred outside (relative risk [RR]=2.01; 95% CI=1.57, 2.58) and at night (RR=1.79; 95% CI=1.40, 2.29). CONCLUSIONS: Security programs should be designed to protect customers as well as employees.

Injuries to high school football athletes in California.

BACKGROUND: Among all high school sports, football has the highest rate of injury. Prior research has been limited primarily because of challenges in surveillance, defining injuries, and measuring exposures. HYPOTHESIS: Football injury patterns differ across player and session characteristics. STUDY DESIGN: Descriptive epidemiology study. METHODS: More than 5000 football players from 87 high schools in California were observed for 2 seasons (2001 and 2002). School representatives were trained to collect data on injuries, player characteristics, and daily exposures. Data were analyzed using descriptive statistics and clustered Poisson regression. RESULTS: Players sustained 25.5 injuries per 100 players, 9.3 injuries per 10,000 player-hours, and 8.4 injuries per 100 session-hours. Session rates were highest during games, on artificial turf (13.8 of 100), during foggy weather (25.1 of 100), and on clear evenings (21 of 100). Offensive and defensive backfielders had about a 20% increased rate of injury compared with linemen. The adjusted injury rate for starters was 60% higher than the rate for nonstarters (relative rate, 1.6; 95% confidence interval, 1.4-1.9). CONCLUSION: Risk profiles differed by experience, playing position, and surface types. We recommend future sports injury research that measures time-dependent exposures at the individual level and for various types of environmental playing conditions.

Suicides at work: misclassification and prevention implications.

To determine the extent of misclassification of suicides with regard to work-relatedness and the implication for intervention, a matched case-control design was used. Cases were identified from California's master mortality file using ICD 9-CM external cause codes E950-959 and a positive response to the "injury-at-work" designation on the death certificate. Two controls matched on the same external cause of death codes, age, date of death, and county of occurrence were randomly selected. Outcome measures were odds ratios and accuracy assessments. Over 11% of cases and 23% of controls were misclassified. Extrapolation to the United States suggests thousands of suicides are misclassified as to a work-related connection. The findings point to misappropriation of the work-relatedness of suicide and hence, an inaccurate understanding of underlying risk factors and their intervention potential.
