Isles S, McBride P, Gee P, Fleischer D, Kappatos D, Pandey R, Civil I, Gabbe B. Prevalence of psychoactive drugs in injured patients presenting to an emergency department. Emerg Med Australas 2023; 35:25-33. [PMID: 35859101 DOI: 10.1111/1742-6723.14040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2022] [Revised: 06/09/2022] [Accepted: 06/12/2022] [Indexed: 01/19/2023]
Abstract
OBJECTIVE The aim of the present study was to obtain an unbiased understanding of the prevalence of psychoactive drugs in trauma patients presenting to a large ED. METHODS Consecutive adult patients presenting to the ED with an injury resulting in a trauma call had an anonymised, additional blood test taken for detection of over 2000 drugs. Laboratory testing was to judicial standards. Drugs given by ambulance pre-hospital were detected but excluded from the analysis. RESULTS Over 6 months 276 (74.7%) of 371 patients were tested. Of the 276 patients tested, 158 (57.2%) had one or more psychoactive drug present. Recreational drugs were detected in 101 (36.6%) patients and medicinal drugs in 88 (31.8%) patients, with a combination of both detected in 31 (11.2%) patients. The most common drugs detected were cannabis (22.1%), antidepressants (18.4%), alcohol (15.5%), opioids (10.1%), benzodiazepine/z-drugs (9.4%) and methamphetamine (7.2%). The prevalence of psychoactive drugs differed by age group, sex and cause of injury. CONCLUSIONS The prevalence of psychoactive drugs in injury presentations to an ED is high, and provides an opportunity to reduce harm. The present study demonstrates the feasibility of an approach which limits bias and obtains results that accurately reflect the drug prevalence in injured cohorts. Systematic testing of injured patients is an important contribution to the epidemiology of injury.

Abstract
OBJECTIVE Examine the driving impairment effects of alcohol alone and of alcohol combined with texting. METHODS Fifteen drivers (nine male, six female; mean age: 31.1 ± 6.9 years, range: 23 to 43 years) with similar drinking habit (i.e., social drinkers) completed a lap in a closed-course section in six different situations: (I) sober; (II) sober and while texting; (III) 30 minutes after ingesting a moderate dose of ethanol (0.50 g/kg); (IV) 30 minutes after drinking and while texting; (V) 60 minutes after drinking, (VI) 60 minutes after drinking and while texting. Driving performance was analyzed by means of maximum and mean speed, braking time and braking distance; and ability to control the car (i.e., evaluating if the drivers hit a traffic cone or exceeded the boundaries of the course). P values of < 0.05 were considered significant. RESULTS Pre and post-alcohol consumption results show a significant increase concerning the drivers' mean and maximum speed after drinking (p < 3.2x10-8). However, neither alcohol nor texting had significant effects on braking parameters (p > 0.05). Traffic cones were knocked down only in texting experiments. In addition, when using the cell phone drivers tended to reduce the speed, and to accelerate abruptly right after they finish texting. CONCLUSION Our findings strengthen the hypothesis that even moderate alcohol doses may significantly impair the driving performance. Additionally, alcohol and texting have complementary effects on driving impairment, and their combination represents a significant risk factor for crashes.

Abstract
BACKGROUND Alcohol consumption is a leading preventable risk factor for morbidity and mortality in China. Understanding drinking patterns provides important data to inform public health policies in alcohol control, especially in specific groups like university students. This study aims to assess the alcohol consumption patterns and level of use in an urban population and a university town in a Chinese city using wastewater-based epidemiology (WBE). METHODS Daily wastewater sample was collected from an urban catchment (n = 270) and every Wednesday's sample from a university town of 10 university campus (n = 43) in 2017-2018. Concentration of alcohol consumption biomarker in wastewater, ethyl sulfate, was measured by direct injection LC-MS/MS analysis. Per capita daily alcohol consumption was then back calculated for assessment purposes. RESULTS Per capita daily alcohol consumption was 1.4 ± 0.6 mL/ person aged 15 + /day (EPD) (range: 0.2-4.9) in the urban catchment and 1.3 ± 0.6 EPD (range: 0.3-2.6) in the university town. Trends of alcohol consumption were stable in both catchments in 2017-2018. Alcohol consumption on weekends (1.5 EPD) and weekdays (1.4 EPD) were at a similar level. Additionally, no difference was observed between holidays (1.5 EPD) and non-holidays (1.4 EPD). CONCLUSION There is a stable weekly drinking level in the studied urban population, which is different compared to studies conducted in Western countries. Our study suggested a similar consumption level between the urban population and university students. Drinking during weekdays could negatively affect China's economic productivity and future public health policies could be adapted to reflect this pattern of drinking.

Park JY, Wu LT. Trends and correlates of driving under the influence of alcohol among different types of adult substance users in the United States: a national survey study. BMC Public Health 2019; 19:509. [PMID: 31054563 PMCID: PMC6500580 DOI: 10.1186/s12889-019-6889-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Accepted: 04/24/2019] [Indexed: 11/21/2022] Open
Abstract
Background Despite a decrease in driving under the influence of alcohol (DUIA) prevalence over the past decades, DUIA prevalence still remains high in the United States. To date, there is limited research examining whether different types of substance users have different trends in DUIA. This study sought to assess trends and variables associated with DUIA by substance use type. Methods National Survey on Drug Use and Health (NSDUH) is a cross-sectional, nationally representative population-based survey. By using the NSDUH 2008–2014, we performed the Joinpoint analysis to identify time trends of DUIA in each group of substance users (aged ≥18 years). Logistic regression analysis was used to explore association between substance use type and DUIA and to identify variables associated with DUIA. Results Adults who reported alcohol or drug use in the past year were classified into different groups based on past-year substance use status: alcohol use only (n = 141,521) and drug use regardless alcohol use. Drug users included prescription opioids only (n = 5337), marijuana only (n = 32,206), other single drug (n = 3789), prescription opioids-marijuana (n = 3921), multiple prescription drugs (n = 1267), and other multiple drugs (n = 18,432). The Joinpoint analysis showed that DUIA prevalence decreased significantly from 2008 to 2014 among alcohol only users (Average Annual Percent Change [AAPC] = − 2.8), prescription opioids only users (AAPC = -5.4), marijuana only users (AAPC = -5.0), prescription opioids-marijuana users (AAPC = -6.5), multiple prescription drug users (AAPC = -7.4), and other multiple drug users (AAPC = -3.2). Although the estimate was not statistically significant, other single drug users showed a decreasing trend (AAPC = -0.9). Substance use type was significantly associated with DUIA in the adjusted logistic regression. All drug use groups, relative to the alcohol only group, had elevated odds of DUIA, and the odds were especially elevated for the multiple drug use groups (prescription opioids-marijuana, adjusted odds ratio [AOR] = 2.71; multiple prescription drugs, AOR = 2.83; and other multiple drugs, AOR = 3.68). Additionally, younger age, male sex, being white, higher income, and alcohol abuse/dependence were positively associated with DUIA. Conclusions DUIA prevalence decreased over time and the magnitude of this reduction differed by substance use type. DUIA interventions need to be tailored to substance use type and individual characteristics.

Abstract
OBJECTIVES The objective of this study was to examine the frequency of psychoactive drugs and alcohol in drivers under suspicion of driving under the influence of drugs and alcohol in 2015 and 2016 in the eastern part of Denmark. The trends in the number of traffic cases sent for drug analysis since 2000 and alcohol analysis since 2011 are also discussed. METHODS Blood samples from drivers suspected of being under the influence of alcohol and/or medication and/or illicit drugs in 2015 and 2016 were investigated as requested by the police. The blood samples were screened for alcohol and/or tetrahydrocannabinol (THC) alone, for other drugs (covering all drugs, except THC, listed in the Danish list of narcotic drugs), or for THC and other drugs. Age and gender were also recorded. The number of drug traffic cases since 2000 and the number of alcohol cases since 2011 were extracted from our Laboratory Information Management System (LIMS). RESULTS In total, 11,493 traffic cases were investigated. Alcohol and/or drugs exceeded the legal limit in 9,657 (84%) cases. Men constituted 95% of the drivers investigated for drugs and 88% of the alcohol cases. The drivers investigated for drugs consisted primarily of young men, whereas drivers investigated for alcohol were older. The frequency was higher for positive alcohol cases above the legal limit (87%) than for drug cases (76%) above the fixed concentration limit. THC (67-69%) was the most frequently detected drug above the legal limit, followed by cocaine (27-28.5%), amphetamine (17%), and clonazepam (6-7%) in both years. Morphine (5.4%), included among the 5 most frequent drugs in 2015, was replaced by methadone (4.6%) in 2016. Few new psychoactive drugs (NPS) were detected. The number of traffic cases sent for drug analysis has increased more than 30-fold since 2000-2006, and the number of traffic cases submitted in 2016 for drug analysis was higher than the number for alcohol analysis; the latter has decreased since 2011. CONCLUSION Overall, alcohol was the most frequent compound detected above the legal limit in both years, followed by the well-known illicit drugs THC, cocaine, and amphetamine. NPS were seldom seen. One consequence of the increased focus on drugs in traffic has been an immense increase in drug traffic cases sent for analysis since 2006 in the eastern part of Denmark. Although this survey revealed only minimal changes compared to earlier investigations, surveys like this are invaluable for monitoring abuse patterns and trends in drugged and drunken driving.

Abstract
BACKGROUND A data acquisition from the medical sector may give one important view of the burden on the society caused by vehicle related injuries. The official police-reported statistics may only reflect a part of all vehicle-related injured seeking medical attention. The aim is to provide a comprehensive picture of the burden of vehicle related injuries on the medical sector (2013), and to compare with official police-reported statistics and the development year 2000-2013. METHODS The data set includes 1085 injured from the Injury Data Base at Umeå University Hospital's catchment area with 148,500 inhabitants in 2013. RESULTS Bicyclists were the most frequently injured (54%). One-third had non-minor (MAIS2+) injuries, and bicyclists accounted for 58% of the 1071 hospital bed days for all vehicle-related injuries. Car occupants represented 23% of all injured, and only 9% had MAIS2+ injuries. They accounted for 17% of the hospital bed days. Motorized two wheel vehicle riders represented 11% of the injured and 39% had MAIS2+ injuries and they occupied 11% of the hospital bed days. Of the 1085 medically treated persons, 767 were injured in public traffic areas, and, therefore, should be included in the official police statistics; however, only a third (232) of them were reported by the police. The annual injury rate had not changed during 2000-2013 for bicyclists, motor-cycle riders, pedestrians or snowmobile riders. However, for passenger car occupants a decrease was observed after 2008, and for mopedists the injury rate was halved after 2009 when a licensing regulation was introduced. CONCLUSION The Swedish traffic injury reducing strategy Vision Zero, may have contributed to the reduction of injured car occupants and moped riders. The official police-reported statistics was a biased data source for vehicle related injuries and the total number medically treated was in total five times higher. Bicyclists caused the heaviest burden on the medical sector; consequently, they need to be prioritized in future safety work, as recently declared in the Government plan Vision Zero 2.0.

Abstract
OBJECTIVE The objective of this study was to understand the social context and circumstances surrounding alcohol-impaired driving prior to fatal crash involvement for drivers with an illegal blood alcohol concentration (BAC ≥ 0.05 g/100 ml or 0.00 g/100 ml for restricted license holders). METHODS Coroners' case reports investigating fatal crashes in South Australia over a 3-year period (2008-2010) were examined. The personal and crash characteristics of drivers with an illegal BAC were compared with those who had a legal BAC. For each driver with an illegal BAC, information was recorded including characteristics of last trip, location and social context of alcohol consumption, quantity and type of alcohol consumed, BAC level, presence of drugs, perceived alcohol intoxication, and alcohol dependence. Official traffic offense records were also obtained. RESULTS Of the 284 fatal crashes included in the study, 34% (n = 95) involved a driver or rider with an illegal BAC. Prior to the crash, alcohol was most frequently consumed by drivers in rural areas, within private homes, and was part of normal social activities. Drivers recorded a high level of alcohol impairment, with a mean BAC of 0.173 g/100 ml and a level of alcohol dependence that was above the Australian national average (7.4 vs. 3.9%). In addition, 23% of drivers were known to be experiencing psychological stress at the time of the crash. The results also confirm that drink driving recidivism continues to be a significant problem, with 44% of drivers recording at least one prior alcohol driving offense. CONCLUSIONS Alcohol-impaired driving continues to be a leading cause of fatal crashes. The popularity of drinking at home, particularly in rural areas, has implications for police enforcement strategies and suggests that drink driving interventions that focus on community values and looking after friends might be beneficial. Importantly, the study highlights the need for a broader holistic approach to reduce the high levels of alcohol consumption and alcohol dependence underlying drink driving behavior.

Abstract
OBJECTIVES The objective of the study was to describe 'the results of the blood alcohol determinations made on drivers from the Liege area between 2007 and 2012. METHODS The results were interpreted according to the sex, to the age, to the circumstances and temporal variation of the test. Statistical analysis was performed using R® software. RESULTS 2725 determinations were done, mainly after crashes. The mean blood alcohol concentration (BAC) was 1.69 g/L, and 2132 drivers were above the legal threshold. A majority of offenders were men, but the mean BAC did not differ significantly between men and women. A correlation between age and mean BAC can be observed on the positive cases. Lowest and highest mean BACs are observed during the daytime and during the night, respectively, but no significant difference can be observed between the week and the weekend. Finally, no significant difference in BAC was observed over years.

Abstract
BACKGROUND It is rare that epidemiological surveys of patients with major trauma include both those admitted to the emergency department and those sent for medico-legal autopsy. The main aim of the present population-based study of major trauma was to examine the importance of medico-legal autopsy data. METHODS A new injury severity score (NISS)>15 or lethal outcome was used as criteria for major trauma and to identify patients at the emergency, anaesthesiology and forensic departments and/or being within the jurisdiction of the Malmö police authority and subjected to a medico-legal autopsy between 2011 and 2013. According to Swedish legislation all trauma related deaths should be reported to the police who refer these cases for medico-legal autopsy. RESULTS Among the 174 individuals included, 92 (53%) died and 81 (47%) underwent medico-legal autopsy. One hundred twenty-six patients were primarily admitted to hospital and 48 died before admission to hospital and were sent directly for medico-legal autopsy. Forty-four in-hospital deaths occurred, of whom 33 (75%) were sent to medico-legal autopsy. In those sent directly to the department of forensic medicine the proportion of accidents was lower (p<0.001), self-inflicted injuries higher (p<0.001) and gunshot wounds higher (p=0.002) in comparison with those sent to hospital. The most prevalent drugs detected by forensic toxicology screening in the 81 fatalities were ethanol (20%), sedatives (16%), anti-depressives (15%) and illicit narcotics (9%). Forty-four cases (54%) were positive for at least one drug, and twenty-eight cases (35%) were positive for two or more drugs. Factors associated with a lower rate of medico-legal autopsies among trauma-related deaths at hospital were high age (p<0.001), lower NISS (p<0.001), a longer duration between trauma and death (p<0.001), falls (p=0.030) and trauma-related infections (p<0.001). CONCLUSION This population based study covering clinical and forensic data shows that more than half of the individuals sustaining major trauma died. An additional 25% of the in-hospital fatalities should have undergone medico-legal autopsy according to legislation, but did not. The high proportion of positive toxicological findings among fatalities examined at medico-legal autopsy implies that toxicology screening should be routine in major trauma patients, in order to improve treatment and prevention.

Abstract
OBJECTIVES We sought to estimate the association between sedative hypnotic use and motor vehicle crash risk. METHODS We conducted a new user cohort study of 409 171 adults in an integrated health care system. Health plan data were linked to driver license and collision records. Participants were aged 21 years or older, licensed to drive in Washington State, had at least 1 year of continuous enrollment between 2003 and 2008, and were followed until death, disenrollment, or study end. We used proportional hazards regression to estimate the risk of crash associated with 3 sedatives. RESULTS We found 5.8% of patients received new sedative prescriptions, with 11 197 person-years of exposure. New users of sedatives were associated with an increased risk of crash relative to nonuse: temazepam hazard ratio (HR) = 1.27 (95% confidence interval [CI] = 0.85, 1.91), trazodone HR = 1.91 (95% CI = 1.62, 2.25), and zolpidem HR = 2.20 (95% CI = 1.64, 2.95). These risk estimates are equivalent to blood alcohol concentration levels between 0.06% and 0.11%. CONCLUSIONS New use of sedative hypnotics is associated with increased motor vehicle crash risk. Clinicians initiating sedative hypnotic treatment should consider length of treatment and counseling on driving risk.

Abstract
OBJECTIVE Employing a sample of 3655 senior students (grades 10 and 12, median ages of 16 and 18, respectively) in Atlantic Canada, this paper examines the risk factors associated with driving under the influence of opioids (DUIO), comparing medical versus recreational opioid users. The associations of DUIO with driving under the influence of alcohol, cannabis, and being a passenger of an impaired driver are also examined. METHODS Participants were drawn from the 2012 Student Drug Use Survey in the Atlantic Provinces, an anonymous cross-sectional survey of junior and senior high school students in three Atlantic Canadian provinces. Logistic regression techniques were employed in the analysis of unadjusted and adjusted models. RESULTS Among all senior students, the prevalence of DUIO in the past year was 4.3%. For those who had used a prescription opioid at least once in the past year, the rate of DUIO was 14%, with a higher rate among medical and recreational users (25.1%) compared to those using opioids only for medical purposes (9.6%). The predictors of DUIO were higher SES, higher sensation seeking, lower parental attachment, and being a recreational prescription opioid user. DUIO was strongly associated with other risky driving and passenger behaviours among recreational opioid users. CONCLUSIONS DUIO is an emerging socio-legal and road safety issue, with implications for public health. Prescription opioid use intentions matter, with recreational users exhibiting most risky driving behaviour than medical users. Effort must be placed on educating prescription opioid users about potential impairment while driving.

Abstract
OBJECTIVES The aim of this study was to investigate polydrug use in drunk drivers. METHODS The experimental study was conducted on 2,072 drunk drivers undergoing a driving license reissue protocol at the Department of Legal Medicine of Padova University Hospital in the period between January 2011 and December 2012. The study protocol involved anamnesis, clinical examination, toxicological history, and toxicological analyses on multiple biological samples. RESULTS One thousand eight hundred seventy-seven subjects (90.6%) were assessed as fit to drive, and 195 (9.5%) were declared unfit. Among those unfit, 32 subjects (1.6%) were declared unfit due to recent use of an illicit drug (time span < 6 months), 23 (1.1%) spontaneously interrupted the protocol before its end, and 140 (6.8%) completed the assessment. Ineligibility to drive after completeness of the protocol was established in 1.2% of cases for alcohol disorders and in 5.7% of cases for illicit drug abuse; only one subject was included in both subgroups. Cocaine was the most widely used substance, followed by cannabis, opiates, and psychotropic pharmaceutical drugs. CONCLUSIONS The application of the protocol presented in this study allowed the identification of underlying polydrug use in drunk drivers. The study led to the identification of 6.8% unfit subjects on the basis of alcohol disorders and/or drug abuse, compared to 1.2% of identifiable unfitness if the protocol were limited to the mere assessment of alcohol consumption. The frequent association of alcohol and cocaine is different from other patterns of use in North Europe countries.

Abstract
INTRODUCTION The impairing effects of combined use of amphetamines and benzodiazepines among recreational drug users are not well described, but knowledge about this is important in the risk assessment of such combined drug use. The aim of this study was to compare the impairment, among apprehended drivers, as judged by a clinical test of impairment (CTI), in cases where a combination of amphetamines and benzodiazepines was detected, in blood, with cases where only one of the two drug groups was detected. METHODS The results of CTI judgments were compared to toxicological drug tests of blood samples that were obtained at the time of CTI screening in cases containing amphetamines only, cases containing different benzodiazepines only, and cases containing a combination of amphetamines and benzodiazepines. RESULTS There were significantly more drivers being judged as impaired in the combined group (n = 777), compared both with amphetamines alone (n = 267, χ(2) = 47.8, p < 0.001) and benzodiazepines alone (n = 153, χ(2) = 7.0, p = 0.008). This was also seen when only including the lowest concentrations of benzodiazepines (χ(2) = 4.3, p = 0.038). The concentrations of the drugs were higher in the single drug groups, compared with the combined group. CONCLUSION This study indicates that during real-life driving, those influenced by both amphetamines and benzodiazepines are more impaired, as judged by the CTI, compared with those influenced by either drug alone, although the combined group showed lower drug concentrations.

Abstract
Riding a motorcycle under the influence of alcohol is a dangerous activity, especially considering the high vulnerability of motorcyclists. The present research investigates the factors that affect the declared frequency of drink-riding among motorcyclists in Europe and explores regional differences. Data were collected from the SARTRE-4 (Social Attitudes to Road Traffic Risk in Europe) survey, which was conducted in 19 countries. A total sample of 4483 motorcyclists was interviewed by using a face-to-face questionnaire. The data were analyzed by means of multilevel ordered logit models. The results revealed significant regional differences (between Northern, Eastern and Southern European countries) in drink-riding frequencies in Europe. In general, declared drinking and riding were positively associated with gender (males), increased exposure, underestimation of risk, friends' behaviour, past accidents and alcohol ticket experience. On the other hand, it was negatively associated with underestimation of the amount of alcohol allowed before driving, and support for more severe penalties.

Abstract
Powered-two-wheelers (PTWs) constitute a very vulnerable type of road users. The notable increase in their share in traffic and the high risk of severe accident occurrence raise the need for further research. However, current research on PTW safety is not as extensive as for other road users (passenger cars, etc.). Consequently, the objective of this research is to provide a critical review of research on Power-Two-Wheeler behaviour and safety with regard to data collection, methods of analysis and contributory factors, and discuss the needs for further research. Both macroscopic analyses (accident frequency, accident rates and severity) and microscopic analyses (PTW rider behaviour, interaction with other motorised traffic) are examined and discussed in this paper. The research gaps and the needs for future research are identified, discussed and put in a broad framework. When the interactions between behaviour, accident frequency/rates and severity are co-considered and co-investigated with the various contributory factors (riders, other users, road and traffic environment, vehicles), the accident and injury causes as well as the related solutions are better identified.

Abstract
Over a period of five years, blood samples were taken from 1046 drivers killed as a result of a motor vehicle crash on New Zealand roads. These were analysed for the presence of alcohol and a range of both illicit drugs and psychoactive medicinal drugs. Driver culpability was determined for all crashes. The control group of drug- and alcohol-free drivers comprised 52.2% of the study population. Drivers positive for psychoactive drugs were more likely to be culpable (odds ratio (OR) 3.5, confidence interval (CI) 95% 2.4-5.2) than the control group. Driver culpability exhibited the expected positive association with alcohol use (OR 13.7, 95% CI 4.3-44) and with combined alcohol and cannabis use (OR 6.9, 95% CI 3.0-16). There was only a weak positive association between cannabis use (with no other drug) and culpability (OR 1.3, CI 95% 0.8-2.3). Furthermore, the OR for drivers with blood tetrahydrocannabinol (THC) concentrations greater than 5 ng/mL was lower (OR 1.0, CI 95% 0.4-2.4) than drivers with blood THC concentrations less than 2 ng/mL (OR 3.1, CI 95% 0.9-10). This is inconsistent with results reported by other studies where a significant increase in crash risk was found with blood THC levels greater than 5 ng/mL. In this study, there were very few drivers who had used a single drug, other than cannabis or alcohol. Therefore, from this study, it is not possible to comment on any relationship between opioid, stimulant or sedative drug use and an increased risk of being killed in a crash for the drivers using these drugs. The results from a multivariate analysis indicate that driver gender, age group and licence status, (P=0.022, P=0.016, P=0.026, respectively), the type of vehicle being driven (P=0.013), the number of vehicles in the crash (P<0.001), the blood alcohol concentration of the driver (P<0.001) and the use of any drug other than alcohol and cannabis (P=0.044), are all independently associated with culpability.

Abstract
Alcohol intoxication plays a significant and causal role in various fatal injuries. In comparison to sober individuals, intoxicated people have a greater generic risk for being involved in hazardous activities that may result in fatal injuries. However, it is not clear whether the biological effects of acute alcohol intoxication result in worse injuries than those sustained by sober individuals who are injured by identical mechanisms. Alcohol intoxication has a neuroprotective effect in experimental animal models of traumatic brain injury (TBI) but the evidence for a similar effect in humans is controversial. Earlier studies found such a protective effect, but more recent large epidemiological studies have not confirmed this finding; some studies also suggest a dose-related protective or exacerbating effect of alcohol intoxication on TBI. There are two apparent alcohol-associated syndromes in which an otherwise survivable blunt force impact to the head of an intoxicated individual is fatal at the scene. The first is a fatal cardiorespiratory arrest (the so-called alcohol concussion syndrome or “commotio medullaris”); the second is “traumatic basilar subarachnoid hemorrhage” (secondary to tears in the cerebral arteries, particularly the intracranial and extracranial vertebral arteries).

Abstract
Sobriety checkpoints are not usually randomly located by traffic authorities. As such, information provided by non-random alcohol tests cannot be used to infer the characteristics of the general driving population. In this paper a case study is presented in which the prevalence of alcohol-impaired driving is estimated for the general population of drivers. A stratified probabilistic sample was designed to represent vehicles circulating in non-urban areas of Catalonia (Spain), a region characterized by its complex transportation network and dense traffic around the metropolis of Barcelona. Random breath alcohol concentration tests were performed during spring 2012 on 7596 drivers. The estimated prevalence of alcohol-impaired drivers was 1.29%, which is roughly a third of the rate obtained in non-random tests. Higher rates were found on weekends (1.90% on Saturdays and 4.29% on Sundays) and especially at night. The rate is higher for men (1.45%) than for women (0.64%) and it shows an increasing pattern with age. In vehicles with two occupants, the proportion of alcohol-impaired drivers is estimated at 2.62%, but when the driver was alone the rate drops to 0.84%, which might reflect the socialization of drinking habits. The results are compared with outcomes in previous surveys, showing a decreasing trend in the prevalence of alcohol-impaired drivers over time.

Abstract
OBJECTIVE To analyze variables associated with recurrence of blood alcohol content (BAC)-related traffic violations among drivers in southern Brazil. METHOD This cross-sectional study included 12,204 driving-under-the-influence (DUI) offenders according to data provided by the Rio Grande do Sul state Transportation Department. Sociodemographic characteristics, license duration, license category, and psychological assessment results were analyzed. Drivers convicted of DUI more than once in 2009/2010 were considered recidivists. Variables were evaluated using descriptive statistical analysis and Poisson regression, adjusted by sex, age, and education level. RESULTS A total of 538 (4.41%) drivers were considered recidivists. The following variables showed the strongest associations with recidivism: being aged 41-50 years (prevalence ratio [PR] = 3.41), being licensed for ≥ 12 years (PR = 1.86), being licensed for motorcycles, cars and trucks (PR = 1.36), having a license with psychological restrictions (PR = 1.33), and driving a truck or a similar vehicle at the moment of notification (PR = 1.08). CONCLUSIONS In the age group with the highest risk for recurrence, drivers showed a higher probability of having a diagnosis of alcohol dependence and other psychiatric comorbidities that hinder the control of alcohol use. Psychological assessments seem to be important in predicting repeat offenses, especially when limited aptitudes are suspected, and should therefore be better investigated.

Abstract
The aim of the study presented here has been to see what the effects of the new traffic safety law are, 2 years into its initial implementation, on driving under the influence of alcohol. Until the end of 2009, the legal limit for blood concentration for drivers in Serbia was 0.5g/l; however, the new traffic safety law stipulates the new limit to be 0.3g/l. A retrospective autopsy study was performed over a 6-year period (from 2006 to 2011) whose sample covered cases of fatally injured drivers who had died at the scene of the incident, before being admitted to hospital. A total of 161 fatally injured drivers were examined for their blood alcohol concentration. The average age for these drivers was 40.2±15.4 years, with a significant male predominance of 152 men to 9 women (χ(2)=152.000, p<0.001). This study has shown no decrease in the ratio of drivers under the influence of alcohol vs. all drivers (Pearson χ(2)=4.415, df=5, p=0.491), nor in the number of drivers under the influence of alcohol (Pearson χ(2)=6.629, df=5, p=0.250), nor a decrease in the mean blood alcohol concentration in drivers (1.72±0.87 vs. 1.68±0.95g/l, t=0.177, df=80, p=0.860). The conclusion of this study is that the new law has had a limited effect on driving under the influence of alcohol, which still remains one of the major human factors, responsible for road-traffic crashes in Serbia.

Abstract
OBJECTIVE To examine the prevalence and factors affecting activity-limiting injuries (ALI) in individuals and in the Canadian population; to estimate the short and long term impact on health status and well-being because of ALI in Canada from 1994 to 2006 using the Canadian National Population Health Survey (NPHS). DESIGN The NPHS is a randomised longitudinal cohort study with biennial interviews, with information on age, sex, education, marital status, income, residence, height and weight to self-perceived health status, healthcare utilisation and medication use in addition to ALI. SETTING The study population was a random sample of male and female participants 20 years and older from 10 provinces and three territories in Canada. PRIMARY AND SECONDARY OUTCOME MEASURES Logistic regression models were used to assess the potential impact of ALI on individuals and on the Canadian population. The interviews 2 years before and 2 years after the ALI were compared to examine long-term effects, and the McNemar test option in SAS was used for the matched analysis. RESULTS The immediate impacts of ALI were pain, disability and disruption of regular life. Long-term effects in patients were chronic pain and increased medical doctor visits. Population impact included a considerable increase in healthcare access and cost. The odds ratios (OR) for the 20-39 age group compared with those 60+ was 2.2; 95% CI 1.8 to 2.7, while the OR associated with male participants was 1.4; 95% CI 1.1 to 1.6. Individuals consuming nine or more alcoholic drinks per week were also significantly more likely to report an ALI (OR, 1.5; 95% CI 1.3 to 1.8). CONCLUSIONS The findings from this study illustrated the immediate and long-term impact of individuals and population level injuries in Canada. Injury control policies should aim to prevent the number of injuries, fatalities as well as the consequences among survivors.

Abstract
OBJECTIVE To study the epidemiology and causes of death in fatal car crashes on Swedish roads in which the victim's vehicle caught fire. METHODS The data set is from the Swedish Transport Administrations in-depth studies of fatal crashes 1998-2008. Autopsies from all cases provided data on injuries, toxicological analyses, and cause of death. RESULTS In total, 181 people died in 133 burning cars, accounting for 5 percent of all deaths in passenger cars, sport utility vehicles, vans, and minibuses during 1998 to 2008. The cause of death for a third of the victims was fire related, as burns and/or smoke inhalation injuries, with no fatal trauma injuries. Twenty-five of these 55 deaths were persons 19 years or younger and included 15 of 18 rear seat deaths. Over half of the 181 deaths were in vehicles that had collided with another vehicle and, of these cases, half were killed in collisions with heavy vehicles. The percentage of drivers with illegal blood alcohol concentrations (27%) and suicides (5.5%) were not higher than in other fatal crashes on Swedish roads. The ignition point of the fire was indicated in only half of the cases and, of those, half started in the engine compartment and one fourth started around the fuel tank or lines. CONCLUSIONS Car fires are a deadly postcrash problem. Reducing this risk would be primarily a responsibility for the automotive industry. A multifactor approach could be considered as follows: risk-reducing design, insulation, reduced flammability in motor compartment fluids and plastics, and automatic fire extinguishing equipment. Inspiration could be found in how, for example, the auto racing and aviation industries handle this problem.

Abstract
OBJECTIVE To estimate the percentage of drivers involved in a traffic crash in Belgium who have alcohol and drugs in their blood. METHODS Blood samples of the drivers injured in a traffic crash and admitted to the emergency departments of 5 hospitals in Belgium between January 2008 and May 2010 were analyzed for ethanol (with an enzymatic method) and 22 other psychoactive substances (with ultra-performance liquid chromatography with tandem mass spectrometry or gas chromatography-mass spectrometry). RESULTS One thousand seventy-eight drivers were included in the study. Alcohol (≥0.1 g/L) was the most common substance (26.2%). A large majority of the drivers (64%) who were positive for alcohol had a blood alcohol concentration (BAC) ≥1.3 g/L (legal limit in Belgium: 0.5 g/L). These high BACs were most frequent among male injured drivers. Cannabis was the most prevalent illicit drug (5.3%) and benzodiazepines (5.3%) were the most prevalent medicinal drugs. Approximately 1 percent of the drivers were positive for cocaine and amphetamines. No drivers tested positive for illicit opioids. Medicinal drugs were more likely to be found among female drivers and drivers older than 35 years, and alcohol and illicit drugs were more likely to be found among male drivers and drivers younger than 35 years. CONCLUSION A high percentage of the injured drivers were positive for a psychoactive substance at the time of injury. Alcohol was the most common substance, with 80 percent of the positive drivers having a BAC ≥0.5 g/L. Compared to a roadside survey in the same area, drivers/riders with high BACs and combinations of drugs were overrepresented. Efforts should be made to increase alcohol and drug enforcement. The introduction of a categorization and labeling system might reduce driving under the influence of medicinal drugs by informing health care professionals and patients.

Abstract
Alcohol is a drug known to impair the ability to drive safely and is acknowledged as a major factor in New Zealand road crashes. However, the use of other impairing drugs by New Zealand drivers is largely unknown. This paper reports the prevalence of drug use by drivers killed on New Zealand roads. As this is a biased population sample the results can only indicate possible drug use in the wider driving population. Blood samples taken from 1046 deceased drivers were analysed for the presence of alcohol and a range of both illicit drugs and psychoactive medicinal drugs. Five hundred and forty-six (52%) of these drivers had not used alcohol or other potentially impairing drugs. Five hundred (48%) had alcohol and/or other drugs in their blood that may have impaired their ability to drive safely. Of these 500 drivers, 135 had used alcohol alone, 96 had used cannabis alone and 142 had used a combination of alcohol and cannabis, but no other drug. Alcohol concentrations in 351 drivers who had drunk alcohol ranged from 5 to 354 mg per 100 mL (mean 152 mg/100 mL). Levels of tetrahydrocannabinol (THC) in the blood of the 314 drivers who had used cannabis ranged from approximately 0.1 ng/mL to 44 ng/mL (mean 5.6 ng/mL). There were 127 drivers who had used some other combination of drugs, many still including alcohol and/or cannabis. Only 29 of the 500 drivers who had used a drug, had not used either cannabis or alcohol and 240 (48%) of the 500 drivers had used more than one potentially impairing drug.

Abstract
AIM To study the results from the toxicological investigations of drivers of cars and vans who were fatally injured in road traffic accidents in 2006-2008 and discuss the findings in relation to the proposed legal limits and impairment thresholds for drugs. METHODS Analyses for alcohol, illegal drugs and psychoactive medicinal drugs were performed by the Norwegian Institute of Public Health. Information on type of accident (single or multiple vehicles) and type of road (urban or rural) was obtained from Statistics Norway. RESULTS Toxicological analyses were requested for 59% of the fatally injured drivers. Drivers involved in single vehicle accidents were more often subject to toxicological investigations, so were also young male drivers and drivers killed on urban roads. Alcohol or drugs were found in concentrations above the current (for alcohol) or proposed (for drugs) legal limits in samples from 37.8% of the drivers; from 64.3% those killed in single-vehicle accidents and 17.9% of those killed in multiple-vehicle accidents. In total, alcohol was found in 25.0%, illicit drugs in 10.2%, and psychoactive medicinal drugs in 13.8% of the samples. Combinations of alcohol and drugs were found in 5.1% and multiple drugs without alcohol in 6.1% of the samples. The prevalence of alcohol or drugs was higher in samples from males than females, higher in samples from young drivers, and higher in samples from drivers killed during weekends. Two thirds of the drivers with alcohol or drug concentrations above the current or proposed legal limits had concentrations above the proposed high impairment threshold. About 60% of the latter ones were impaired by alcohol only, 20% by drugs in combination with alcohol, and 20% by drugs only, mainly due to multi-drug use. CONCLUSION The use of alcohol or drugs before driving was a significant contributing factor in fatal road traffic accidents, particularly in single vehicle accidents, and particularly among young male drivers. Alcohol was the most significant intoxicant, but multi-substance use was also significantly prevalent. The majority of the drivers with alcohol or drug findings were strongly impaired.

Abstract
In many countries, benzodiazepines are the most commonly used and misused psychoactive medicinal drugs. Results of epidemiological studies investigating the association between benzodiazepine use and traffic accidents seem to be inconclusive or inconsistent at first sight. However, the outcome of epidemiological studies may be influenced by several methodological factors like study design, study population, exposure measurement, outcome definitions and possible confounders. Our objective was to conduct a systematic literature review of epidemiological studies that investigated the association between benzodiazepine use and traffic accidents, including related outcomes like culpability and injury or accident severity. We searched EMBASE, PubMed and Forensic Science Abstracts 3/0 (FORS) for references included in these databases at 1 June 2009 using the term 'benzodiazepines' in combination with 'driving performance' or 'accident risk' or 'traffic accident'. For inclusion in this review, the study design had to be comparative, include road users involved in accidents and provide specific data about benzodiazepines. Sixty-six studies were included in the review. The study populations varied from the general (driving) population, accident-involved road users with or without injury and persons admitted to a hospital to fatally injured accident-involved drivers. Exposure assessment was performed by using toxicological results, prescription data or questionnaires. The divergent study populations and comparison groups and the variety of methods used to express the outcome of interest hampered comparison between results. Evidence is growing that exposure to benzodiazepines is related to increased accident risk. The literature indicates that the greatest accident risk is associated with the use of long half-life benzodiazepines, increasing dosage and the first few weeks of use of benzodiazepines. Clear evidence of increased culpability associated with benzodiazepine use is scarce. More research has to be done to elucidate the relationship between benzodiazepine use and injury severity.

Abstract
OBJECTIVE To assess the temporal trends in the incidence and demographic characteristics of traumatic spinal cord injury (TSCI) with clinical concomitant traumatic brain injury (TBI), in an unselected, geographically defined cohort, 1952-2001. MATERIAL AND METHODS The patients were identified from hospital records. TBI was classified as none, mild, moderate, and severe. RESULTS Of 336 patients, 157 (46.7%) patients had a clinical concomitant TBI. Clinical TBI was classified as mild in 30.1%, moderate in 11.0% and severe in 5.7%. The average annual incidence increased from 3.3 per million in the first decade to 10.7 per million in the last. Alcohol was the strongest risk factor of clinical TBI (OR = 3.69) followed by completeness of TSCI (OR = 2.18). CONCLUSIONS The incidence of TSCI with concomitant TBI has increased during the last 50 years. Alcohol and completeness of injury are strong risk factors. Increased awareness of dual diagnoses is necessary.
