Injury prevention and recreational all-terrain vehicle use: the impact of helmet use in West Virginia.

UNLABELLED: All-terrain vehicles (ATVs) are a popular source of outdoor activity in the United States, particularly in West Virginia. During the period of time from 1999 to 2007, deaths associated with ATVs in West Virginia increased by 28%. Helmet use among bicycle and motorcycle riders has been shown to decrease morbidity and mortality following trauma. METHODS: We performed a retrospective observational study to compare injury patterns, hospital course, and resource utilization of non-helmeted and helmeted riders involved in ATV accidents using data from the West Virginia Trauma Center System. Descriptive statistics were calculated for all study variables and comparisons were made between helmeted and non-helmeted riders. RESULTS: In 2010, there were 1,059 patients aged 18 and over with traumas resulting from ATV accidents within the System. Riders involved in ATV trauma occurring on farms and streets were significantly more likely to be non-helmeted, while those using ATVs for recreational purposes were more likely to be helmeted. Non-helmeted riders were significantly more likely to arrive to the hospital via helicopter than helmeted riders, and were less likely to be discharged home from the ED compared to helmeted riders. Non-helmeted riders sustained significantly more head, neck, soft tissue injuries, concussions, intracranial hemorrhages, facial fractures, skull fractures, and thoracic spine fractures than helmeted riders. DISCUSSION: The findings of the current study support previous studies documenting that helmet use is protective against intracranial injury and other injuries of the head and neck. ATV use continues to be a significant contribution to trauma morbidity and mortality in West Virginia. CONCLUSION: Efforts that focus on increased helmet use have the potential to significantly reduce morbidity and mortality following ATV trauma. Enforcement of the current West Virginia ATV Law should be encouraged. Legislation expanding the mandatory use of safety equipment and rider training should be enacted in West Virginia.

Major trauma in West Virginia dementia patients injury patterns, discharge dispositions and implications for treatment and injury prevention.

Our study examines injury patterns, treatment implications, discharge disposition, and injury prevention for trauma patients with dementia. It is a retrospective observational study of trauma patients at the Jon Michael Moore Trauma Center at West Virginia University Hospitals. Causes of injury, injuries sustained, and discharge disposition were examined in 286 trauma patients with a pre-existing diagnosis of dementia and 5,865 trauma patients without dementia. All patients included in this study were 40 years of age or older. Injury data were compiled for patients with dementia. Causes of injury and discharge disposition were compared for the two groups.

Violence in the emergency department: a national survey of emergency medicine residents and attending physicians.

BACKGROUND: Violence in the Emergency Department (ED) is a well-known phenomenon. Few studies have been done to assess the incidence and nature of violence in the ED. STUDY OBJECTIVES: The purpose of this study was to assess the incidence of violence in the ED nationwide. METHODS: This study was a prospective, cross-sectional online survey of Emergency Medicine (EM) residents and attending physicians. Of the 134 accredited United States (US) EM residency programs, 65 programs were randomly selected and invited to participate. RESULTS: Overall, 272 surveys were returned, of which 263 (97%) were completed and further analyzed. At least one workplace violence act in the previous 12 months was reported by 78% (95% confidence interval 73-83%) of respondents, with 21% reporting more than one type of violent act. Workplace violence was experienced similarly between males and females (79% vs. 75%, respectively; p = 0.65), and was more common in EDs with annual volumes over 60,000 patients (82% vs. 67%; p = 0.01). The most common type of workplace violence was verbal threats (75%) followed by physical assaults (21%), confrontations outside the workplace (5%), and stalking (2%). Security was available full time in most settings (98%), but was least likely to be physically present in patient care areas. The majority of respondent EDs did not screen for weapons (40% screened) or have metal detectors (38% had metal detectors). Only 16% of programs provided violence workshops, and less than 10% offered self-defense training. CONCLUSION: Despite the high incidence of workplace violence experienced by the emergency physicians who responded to our survey, less than half of these respondents worked in EDs that screened for weapons or had metal detectors. An even smaller number of physicians worked in settings that provided violence workshops or self-defense training.

Hospitalizations for poisoning by prescription opioids, sedatives, and tranquilizers.

BACKGROUND: Unintentional poisoning deaths have been increasing dramatically over the past decade, and the majority of this increase has resulted from overdoses of specific prescription drugs. Despite this trend, there are limited existing data examining hospitalizations for poisonings, both unintentional and intentional, associated with prescription drugs. A better understanding of these hospitalizations may help identify high-risk populations in need of intervention to prevent subsequent mortality. PURPOSE: This article aims to describe the incidence and characteristics of hospitalizations resulting from poisoning by prescription opioids, sedatives, and tranquilizers in the U.S. from 1999 to 2006 and make comparisons to hospitalizations for all other poisonings during this time period. METHODS: Hospitalizations for poisonings were selected from the Nationwide Inpatient Sample (NIS), a stratified, representative sample of approximately 8 million hospitalizations each year, according to the principal discharge diagnosis. Intentionality of the poisoning was determined by external cause of injury codes. SAS callable SUDAAN software was used to calculate weighted estimates of poisoning hospitalizations by type and intentionality. Demographic and clinical characteristics of poisoning cohorts were compared. Data were analyzed in 2009. RESULTS: From 1999 to 2006, U.S. hospitalizations for poisoning by prescription opioids, sedatives, and tranquilizers increased a total of 65%. This increase was double the increase observed in hospitalizations for poisoning by other drugs and substances. The largest increase in the number of hospitalized cases over the 7-year period was seen for poisonings by benzodiazepines, whereas the largest percentage increase was observed for methadone (400%). In comparison to patients hospitalized for poisoning from other substances, those hospitalized for prescription opioids, sedatives, and tranquilizers were more likely to be women, aged >34 years, and to present to a rural or urban nonteaching hospital. CONCLUSIONS: Prescription opioids, sedatives, and tranquilizers are an increasing cause of hospitalization. The hospital admission provides an opportunity to better understand the contextual factors contributing to these cases, which may aid in the development of targeted prevention strategies.

Case report: esophageal foreign body mistaken for impacted button battery.

Foreign body ingestion is a common complaint in the pediatric emergency department. Here, we report an interesting case of a coin ingestion in which the radiographic findings were alarming and inconsistent with the history provided by our patient. A brief review of the diagnosis and management of gastrointestinal foreign bodies is presented, with particular focus on ingested coins and button batteries.

The effect of ethanol on uncontrolled hemorrhage in a rodent model.

OBJECTIVES: Ethanol intoxication has hemodynamic and metabolic effects after hemorrhage according to studies using fixed-volume controlled blood loss models. The authors tested the null hypothesis that after uncontrolled hemorrhage there would be no difference in the hemodynamic responses between ethanol-intoxicated (EtOH+) and nonintoxicated (EtOH-) rats. METHODS: Forty Sprague-Dawley rats were anesthetized with althesin intraperitoneally. Twenty EtOH+ rats received a 3-g/kg dose of 20% ethanol intraperitoneally 60 minutes before hemorrhage. The EtOH- rats received an equivalent volume of normal saline intraperitoneally. The femoral artery was cannulated by cutdown to monitor the mean arterial blood pressure (MAP) and to obtain blood samples for lactate (LAC). Twenty rats (ten EtOH+ and ten EtOH-) underwent uncontrolled hemorrhage by 75% tail amputation. Twenty rats (ten EtOH+ and ten EtOH-) served as nonhemorrhage controls. The MAP, LAC, and cumulative hemorrhage volume were measured prehemorrhage and then every 15 minutes posthemorrhage for 120 minutes. Data were reported as mean +/- SEM. Group comparisons were analyzed by analysis of variance with repeated values and post hoc testing by Bonferroni (two tailed; alpha = 0.05). RESULTS: Initially, EtOH+ and EtOH- rats were evenly matched for LAC and MAP. The mean (+/-SD) baseline ethanol level was 170 (+/-68) mg/dL in EtOH+ rats. Cumulative hemorrhage volume was similar (p = 0.23) for the EtOH- (2.36 +/- 0.24 mL/100 g) and EtOH+ (1.87 +/- 0.32 mL/100 g) rats. No significant difference was noted in posthemorrhage MAP between EtOH- (68.6 +/- 6.8 mm Hg) and EtOH+ (69.3 +/- 7.2 mm Hg) rats (p = 1.00). The EtOH- group had a significantly higher LAC (4.94 +/- 1.07 mmol/L) than the EtOH+ group (2.27 +/- 0.59 mmol/L) (p < 0.03). CONCLUSIONS: Ethanol intoxication does not deleteriously affect the hemodynamic response to uncontrolled hemorrhage.
