Fatal crash between a car operating with automated control systems and a tractor-semitrailer truck.

Objective: The objective of this investigation was to evaluate the interaction between an SAE level 2 automated vehicle and the driver, including the limitations imposed by the vehicle on the driver.

Methods: A case study of the first fatal crash involving a vehicle operating with an automated control system was performed using scene evidence, vehicle damage, and recorded data available from the vehicle, and information from both drivers, including experience, phone records, computer systems, and medical information, was reviewed.

Results: System performance data downloaded from the car indicated that the driver was operating it using the Traffic-Aware Cruise Control and Autosteer lane-keeping systems, which are automated vehicle control systems within Tesla's Autopilot suite.

Changes in baseline concussion assessment scores following a school bus crash.

Objective: The objective of this article is to present concussion assessment data for 30 male athletes prior to and after being involved in a large school bus crash. The athletes on the bus, all male and aged 14-18 years, were participants in their school's concussion management program that included baseline and postinjury testing using Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT).

Methods: This case study described changes in concussion assessment scores for 30 male athletes following a primarily frontal school bus crash.

23 years of toxicology testing fatally injured pilots: Implications for aviation and other modes of transportation.

Unlabelled: Use of over-the-counter, prescription, and illicit drugs is increasing in the United States (US). Many of these drugs are psychoactive and can affect the user's ability to safely operate a vehicle. However, data about drug use by vehicle operators is typically limited to a small proportion of operators and a short list of drugs.

Fatal Consequences: Obstructive Sleep Apnea in a Train Engineer.

This special report describes the findings of the National Transportation Safety Board's investigation into the probable cause of the derailment of a Metro-North passenger train in the Bronx, New York on December 1, 2013, that resulted in 4 deaths and injuries to 59 additional persons. A key finding in the medical investigation was the engineer's post-accident diagnosis of severe, obstructive sleep apnea, and the probable cause of the accident was determined to be the result of the engineer having fallen asleep while operating the train. This accident highlights the importance of screening, evaluating, and ensuring adequate treatment of obstructive sleep apnea, particularly among patients working in positions where impairment of physical or cognitive function or sudden incapacitation may result in serious harm to the public.

Exceeding the speed limit: prevalence and determinants in Iran.

Speeding is one of the most common risk behaviours associated with crashes causing signficant injury. The objective of this study is to explore the prevalence and determinants of speeding on a road between Tehran and Hamadan, Iran. In a cross-sectional study in 2009, stretches of the road were studied including three groups of posted speed limits: < 50 km/h, 50-100 km/h and > 100 km/h.

The epidemiology of mountain bike park injuries at the Whistler Bike Park, British Columbia (BC), Canada.

Objective: To describe the epidemiology of injuries sustained during the 2009 season at Whistler Mountain Bike Park.

Methods: A retrospective chart review was performed of injured bike park cyclists presenting to the Whistler Health Clinic between May 16 and October 12, 2009.

Results: Of 898 cases, 86% were male (median age, 26 years), 68.

Trauma registries: history, logistics, limitations, and contributions to emergency medicine research.

Trauma registries have been designed to serve a number of purposes, including quality improvement, injury prevention, clinical research, and policy development. Since their inception over 30 years ago, there are increasingly more institutions with trauma registries, many of which submit data to a national trauma registry. The goal of this review is to describe the history, logistics, and characteristics of trauma registries and their contribution to emergency medicine and trauma research.

The effect of driver age on the incidence and severity of upper extremity injuries due to second generation front air bag deployment.

This study used NHTSA NASS/CDS data to examine whether advancing age was associated with a higher incidence and severity of front airbag-related upper extremity injury (UEI). Using a retrospective cohort design we analyzed weighted data from 1998-2007 for. The study population consisted of lap/shoulder belted people over 16 years of age who were driving passenger vehicles with model years 1998-2003 and were involved in a frontal crash where their front airbag deployed.

Serious injuries related to the Segway® personal transporter: a case series.

Study Objective: We describe a case series of emergency department (ED) visits for injuries related to the Segway® personal transporter.

Methods: This was a retrospective case review using a free-text search feature of an electronic ED medical record to identify patients arriving April 2005 through November 2008. Data were hand extracted from the record, and further information on admitted patients was obtained from the hospital trauma registry.

National survey of emergency department alcohol screening and intervention practices.

Study Objective: We describe current alcohol screening and brief intervention practices in emergency departments (EDs) at Level I and Level II trauma centers and characterize ED directors' attitudes and perceived barriers associated with these practices among injured patients in the ED.

Methods: ED directors at Level I and Level II trauma centers were surveyed about current alcohol screening and intervention practices in the ED, as well as knowledge, attitudes, and perceived barriers to these practices.

Results: Nearly half (46.

Analysis of emergency medical services activations in Shenandoah National Park from 2003 to 2007.

Background: Wilderness activities continue to be popular in the United States, but may lead to both direct injuries and exacerbations or complications from chronic diseases. Appropriate response planning requires information on the type and location of emergency medical services (EMS) activations in large outdoor areas with many visitors.

Objectives: To describe EMS calls in Shenandoah National Park in Virginia and explore the resultant implications for EMS resources and staging, medical provider training, and potential public health interventions in similar wilderness recreation areas.

Public health in the emergency department: overcoming barriers to implementation and dissemination.

This article is the outcome of a consensus building workshop entitled, "Overcoming Barriers to Implementation and Dissemination" convened at the 2009 Academic Emergency Medicine Consensus Conference, ''Public Health in the ED: Surveillance, Screening, and Intervention." The participants were asked to address potential methods for overcoming barriers to the dissemination and implementation in the emergency department (ED) of evidenced-based practices to improve public health. The panel discussed three broad areas of interest including methods for disseminating evidence-based practices, barriers encountered during the process of implementation, and the importance of involvement in activities outside the ED including engagement in policy development and improvement.

Six-month follow-up of a brief intervention on self-reported safety belt use among emergency department patients.

Objectives: Safety belt use (SBU) reduces motor vehicle deaths by 45%. We previously reported that a brief intervention improved self-reported SBU among emergency department (ED) patients at 3 months. We sought to determine if these effects were sustained at 6 months postenrollment.

Mastitis and methicillin-resistant Staphylococcus aureus (MRSA): the calm before the storm?

Background: Post-partum mastitis is a common infection in breastfeeding women, with an incidence of 9.5-16% in recent literature.
