AbstractThis report describes the methodology for the 2007 U.S. national field study to estimate the prevalence of alcohol-, drug-, and alcohol-and-drug-involved driving, primarily among nighttime weekend drivers, but also daytime Friday drivers. This study involved randomly stopping drivers at 300 locations across the continental United States; sites were selected through a stratified random sampling procedure. Data were collected during a 2-hour Friday daytime session at 60 locations, and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on both Friday and Saturday nights) at 240 locations. Both self-report and biological measures were taken. An objective was to obtain at least 7,500 oral fluid samples for analysis. Biological measures included breath alcohol measurements on 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents. Oral fluid and blood samples were subjected to laboratory screening and LC/MS-MS and GC/MS confirmation respectively for both alcohol and 20 categories of drugs. These data are being analyzed to develop the first national prevalence estimate of alcohol-and drug-involved driving. This first report describes the field methods used to conduct this study, including data collection procedures. Overall response rates are also presented. Two other reports will present the results of the data collection and analyses; one will focus on alcohol use prevalence estimates among drivers and compare them with previous National Roadside Surveys conducted in 1973, 1986, and 1996; the other report will provide drug use prevalence estimates among drivers. AcknowledgementsThe authors would like to acknowledge the extensive assistance we received from State and local officials in the conduct of this project. Our data collection procedures were not routine by any means and the willingness of State officials to help us identify local police agencies and the agencies' willingness to participate in the project were essential to our success.
ABSTRACT. Objective: The purpose of this study was to determine whether the relative risk of being involved in an alcohol-related crash has changed over the decade from 1996 to 2007, a period during which there has been little evidence of a reduction in the percentage of all fatal crashes involving alcohol. Method: We compared blood-alcohol information for the 2006 and 2007 crash cases (N = 6,863, 22.8% of them women) drawn from the U.S. Fatality Analysis Reporting System (FARS) with control blood-alcohol data from participants in the 2007 U.S. National Roadside Survey (N = 6,823). Risk estimates were computed and compared with those previously obtained from the 1996 FARS and roadside survey data. Results: Although the adult relative risk of being involved in a fatal alcohol-related crash apparently did not change from 1996 to 2007, the risk for involvement in an alcohol-related crash for underage women has increased to the point where it has become the same as that for underage men. Further, the risk that sober underage men will become involved in a fatal crash has doubled over the 1996-2007 period. Conclusions: Compared with estimates obtained from a decade earlier, young women in this study are at an increased risk of involvement in alcohol-related crashes. Similarly, underage sober drivers in this study are more at risk of involvement in a crash than they were a decade earlier. (J. Stud. Alcohol Drugs, 73, 341-350, 2012)

The National Institute on Alcohol Abuse and Alcoholism (NIAAA) provided funding and support for the assessment of alcohol use disorders.

AbstractThis report presents the prevalence estimates for alcohol-involved driving derived from the recently completed U.S. national field survey of alcohol-and drug-involved driving (primarily of nighttime weekend drivers, but also daytime Friday drivers) and compares those estimates with the three previous National Roadside Surveys. This survey involved randomly stopping drivers at 300 locations across the 48 contiguous United States. Data were collected during 2-hour Friday daytime sessions (9:30 a.m. to 11:30 a.m. or 1:30 p.m. to 3:30 p.m.) at 60 locations and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on Fridays and Saturdays) at 240 locations. Both self-report and biological measures were taken. Biological measures included breath-alcohol measurements on 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents. A prior report described the sampling plan and data collection methodology and summarized the response patterns to the various stages of the multipart survey. A third report, based on analyses of the oral fluid and blood specimens collected, will present the first national prevalence estimate of drug-involved driving and of alcohol-plus-drug-involved driving. This report focuses on the alcohol breath-test results and how they relate to previous national surveys. It also summarizes response patterns to survey questions and to an alcohol-use-disorder-screening instrument. The data indicate a continuing trend over the past three decades of fewer alcohol-involved drivers on the Nation's roads during weekend nights.
This article describes the methodology used in the 2007 U.S. National Roadside Survey to estimate the prevalence of alcohol- and drug-impaired driving and alcohol- and drug-involved driving. This study involved randomly stopping drivers at 300 locations across the 48 continental U.S. states at sites selected through a stratified random sampling procedure. Data were collected during a 2-hour Friday daytime session at 60 locations and during 2-hour nighttime weekend periods at 240 locations. Both self-report and biological measures were taken. Biological measures included breath alcohol measurements from 9,413 respondents, oral fluid samples from 7,719 respondents, and blood samples from 3,276 respondents.
In our prospective study of prehospital LSIs performed in a combat zone, we observed a higher rate of incorrectly performed and missed LSIs in airway and chest (breathing) interventions than hemorrhage control interventions. The most commonly performed LSIs had lower incorrect and missed LSI rates.
Weapon injuries other than gunshot wounds or low-velocity stab wounds to the head are extremely rare. We report the case of a 6-year-old girl who sustained a penetrating craniocerebral injury after being accidentally shot with an underwater fishing harpoon. This mechanism of injury seems to share characteristics of both high- and low-velocity projectiles. We discuss the management of this unusual injury in a child, remarking that foreign body removal in these cases must be carried out following the original direction of the projectile trajectory. We review the current literature on craniocerebral injuries caused by similar objects, especially those occurring in children.
Introduction The literature presents a puzzling picture of Latinos being overrepresented in alcohol-related crashes, but not in noncrash drinking and driving. This report examines if, like other demographic variables in which some groups are at a higher crash risk than others (e.g., young drivers), different racial/ethnic groups face different crash risks Method This study compares blood-alcohol information from the 2006–2007 U.S. Fatality Analysis Reporting System (FARS) with control data from the 2007 U.S. National Roadside Survey. Logistic regression, including a dual interaction between BAC and race/ethnicity, was used to estimate crash risk at different BAC levels. Results It was found that, although Hispanic and African-American drivers were less likely to be involved in single-vehicle crashes than their White counterparts, all drivers face similar BAC relative crash risk regardless of their group membership. The overrepresentation of Latino drivers in alcohol-related crashes could be explained by differences in patterns of consumption, driving exposure, lack of awareness of driving rules, and/or socioeconomics.
