Abstract
Recovery from injury involves painful movement and activity, painful stretches and muscle strengthening, and adjustment to permanent impairment. Recovery is facilitated by embracing the concept that painful movement can be healthy, which is easier when one has more hope, less worry, and greater social supports and security. Evolution of one's identity to match the new physical status is a hallmark of a healthy outcome and is largely determined by mental and social health factors. When infection, loss of alignment or fixation, and nerve issues or compartment syndrome are unlikely, greater discomfort and incapability that usual for a given pathology or stage of recovery signal opportunities for improved mental and social health. Surgeons may be the clinicians most qualified to make this discernment. A surgeon who has gained a patient's trust can start to noticed despair, worry, and unhelpful thinking such as fear of painful movement. Reorienting people to greater hope and security and a healthier interpretation of the pains associated with the body's recovery can be initiated by the surgeon and facilitated by social workers, psychologist, and physical, occupational and hand therapists trained in treatments that combine mental and physical therapies.

Abstract
BACKGROUND Trauma centers are required to screen patients for alcohol use, and if necessary, intervene and refer to treatment (SBIRT). Similar screening for illicit drug use is recommended but not required. Urine drug screening (UDS) underestimates problematic substance use. This study aimed to estimate the types and rates of UDS false negatives (FN) compared to comprehensive testing by liquid chromatography-mass spectrometry (LC-MS) in trauma patients. METHODS We performed a prospective cohort study of deidentified urine samples from adult trauma and burn activation patients. Both UDS and LC-MS comprehensive testing of >200 analytes were performed by a reference laboratory on all samples. Iatrogenic medications were excluded from the FN count. Crosstab analyses were conducted for UDS versus LC-MS outcomes to establish FN types and rates. We dichotomized the results by creating an "intentionality" variable (intentional injuries by self/others versus accidental injuries). A series of crosstabs with odds ratios considered intentionality by substance class and demographics. Statistically significant variables by Chi-Square were assessed by logistic regression. RESULTS Psychoactive FN were detected in 56/100 urine samples analyzed; the most frequent included anticonvulsants (primarily gabapentin, N = 13), opioid agonists (N = 12), antihistamines (primarily diphenhydramine, N = 10), and phenethylamines (primarily bupropion, N = 5). Nonpsychoactive FN were detected in 70/100 samples; the most common were nicotine (N = 33), caffeine (N = 23), acetaminophen (N = 22), and antidepressants (N = 12). Of substance classes included in the UDS and also tested by LC-MS, FN occurred for opiates (3%), amphetamines (5%) and opioids (25%). Polypharmacy was associated with fall injuries in elderly patients. Cocaine (p = 0.015) and cannabinoids (p = 0.002) were significantly associated with intentionality. CONCLUSIONS Our results indicate that FN for potentially important psychoactive and nonpsychoactive substances are common when toxicologic testing is limited to routine UDS in trauma patients. We recommend expanding SBIRT in this patient population to include misuse of tobacco products, prescription analgesics, and over-the-counter antihistamines.

Abstract
Background Motor vehicle accidents (MVAs) are one of the main causes of mortality in developing countries. Although the association between alcohol and the risk of MVA has been known for a long time, only a few studies have been conducted on driving following substance consumption in a short period of time. This is while narcotic and stimulant use seems to be a threat to traffic safety and a serious health concern for substance users. In this study, we investigated the prevalence of substance use (narcotics and stimulants) in drivers with traffic injuries admitted to the orthopedic ward of Imam Khomeini Hospital between October 2020 and June 2021. Methods The current research is a cross-sectional, descriptive-analytical study. The statistical population consisted of 77 patients admitted to the orthopedic ward of a training hospital (Imam Khomeini) in Mazandaran Province, northern Iran. The Shapiro-Wilk test was used to determine the quantitative variables. The sampling method is random and consecutive. The method of data collection was through questionnaire tools. The software used was SPSS 26 with an independent t-test, Mann–Whitney U test, Chi-square or Fisher's exact test. Results In this study, the frequency of substance use was 18.18%. The prevalence of opioid usage was 35.7% and for stimulants it was 64.28%. There was no case of concomitant use of opioids and stimulants. In the opioid group, 60% of patients used opium, 20% methadone, and 20% tramadol. In the stimulant and alcohol groups, 12.12% utilized methamphetamine and 88.88% drank alcohol. The average age of consumers was 39 years, which was significantly higher in the opioid group (P = 0.040). The education level of substance users was remarkably lower (P < 0.05) and, occupationally, there was no statistically significant difference between groups of substance users (P = 0.290). Considerably, the unemployed population consumed more substances (P = 0.001). Multiple fractures (P < 0.05) and surgical treatment (P = 0.012) were more common in the user group. Conclusion Users of stimulants and alcohol were younger than opioid users, according to our results. There is an association between drug use and the incidence of traffic accidents, as well as lower educational levels, masculinity, fracture type, and patient complication type. Association between drug use and the incidence of traffic accidents. Substance use has the ability to disrupt attention. Most drivers who suffer from severe accidents can be caused by the Substance use.

Abstract
INTRODUCTION Australasian emergency departments (ED) routinely test patient alcohol levels following major trauma, but assessment for illicit drugs is uncommon. METHODS A prospective cross-sectional study of major motor-vehicle-related trauma patients attending both adult major trauma centres in Victoria, Australia. All eligible patients had point-of-care saliva testing to determine the prevalence of common illicit drugs. RESULTS Over 12 months, 1411 patients were screened, 36 refused (2.6%) and 63 were excluded. Of the final 1312 cases included, 173 (13.2%; 95% confidence interval 11.5, 15.1) tested positive to at least one illicit substance, with 133 (76.9%; 69.7, 82.8) positive for meth/amphetamines. One in five had more than one illicit substance detected. Patients testing positive were most frequently in motor vehicles (91.9% vs. 85.6%) and least frequently cyclists (2.3% vs. 4.2%) or pedestrians (5.2% vs. 10.3%), compared to those testing negative. They were younger (mean age 35.4 vs. 43.1 years), more likely to arrive overnight (27.2% vs. 12.1%) or after single vehicle crashes (54.3% vs. 42.3%). Although the initial disposition from ED did not differ, those testing positive were more likely to re-present within 28 days (13.9% vs. 5.4%). DISCUSSION AND CONCLUSIONS A high prevalence of potentially illicit substances among patients presenting with suspected major trauma supports the need for urgent preventive strategies. The low rate of patient refusal and large numbers screened by ED staff suggests that point-of care testing for illicit substances in major trauma is acceptable and feasible. This study and ongoing surveillance may be used to inform driver education strategies.

Abstract
BACKGROUND Opium addiction is associated with multiple physical, psychological, and social problems. The aim of this study was to compare the risk of morbidity and mortality in opium-addicted and non-addicted trauma patients admitted to the intensive care units (ICUs) of trauma center of Kerman Province, Iran. METHODS In this cohort study, a total of 200 addict and non-addicted patients who were admitted due to trauma in ICUs of Shahid Bahonar Hospital in Kerman during 9 months of 2018 were included. Patients were compared in terms of mortality, incidence of pressure ulcers, incidence of organ failure, duration of mechanical ventilation, and duration of hospitalization. Data were analysed using Fisher's exact test and independent t-test at P < 0.05. FINDINGS Out of 197 examined patients, 161 (81.7%) individuals were men and 36 (18.3%) were women. Moreover, 98 (49.7%) patients had a history of opium abuse, while 99 (50.2%) patients had no history of opium addiction. The addicted and non-addicted groups had no significant differences in terms of age (P = 0.650) and gender (P = 0.580). In addicted patients, mortality, duration of mechanical ventilation (P = 0.027), the incidence of pressure ulcer, and organ failure were significantly higher (P < 0.001), but mean ICU stay and hospitalization time was the same in both groups. CONCLUSION The results of this study indicated higher mortality and morbidity in opium-addicted patients admitted to ICU than non-addicted ones. This suggests that various systems of the body are affected by opium and, in certain circumstances such as severe diseases, this will cause problems for patients. Therefore, experts should pay attention to complications and side effects of addiction in the management of critical patients with a history of opium abuse.

Abstract
Driving under the influence of cannabis and alcohol represents a major safety concern due to the synergistic or additive effect of these substances of abuse. Hence, rapid road-site testing of these substances is highly desired to reduce risks of fatal accidents. Here we describe a wearable electrochemical sensing device for the simultaneous direct, decentralized, detection of salivary THC and alcohol. The new ring-based sensing platform contains a voltammetric THC sensor and an amperometric alcohol biosensor on the ring cap, along with the wireless electronics embedded within the ring case. Rapid replacement of the disposable sensing-electrode ring cap following each saliva assay is accomplished by aligning spring-loaded pins, mounted on the electronic board (PCB), with the current collectors of the sensing electrodes. The printed dual-analyte sensor ring cover is based on a MWCNT/carbon electrode for the THC detection along with a Prussian-blue transducer, coated with alcohol oxidase/chitosan reagent layer, for the biosensing of alcohol. THC and alcohol can thus be detected simultaneously in the same diluted saliva sample within 3 min, with no cross talk and no interferences from the saliva matrix. The new wearable ring sensor platform should enable law enforcement personnel to screen drivers in a single traffic stop and offers considerable promise for addressing growing concerns of drug-impaired driving.

Abstract
Marijuana is listed as a Schedule I substance under the American Controlled Substances Act of 1970. As more U.S. states and countries beyond the U.S. seek legalization, demands grow for identifying individuals driving under the influence (DUI) of marijuana. Currently no roadside DUI test exists for determining marijuana impairment, thus the merit lies in detecting the primary and the most sought psychoactive compound tetrahydrocannabinol (THC) in marijuana. Salivary THC levels are correlated to blood THC levels making it a non-invasive medium for rapid THC testing. Affinity biosensing is leveraged for THC biomarker detection through the chemical reaction between target THC and THC specific antibody to a measure signal output related to the concentration of the targeted biomarker. Here, we propose a novel, rapid, electrochemical biosensor for the detection of THC in saliva as a marijuana roadside DUI test with a lower detection limit of 100 pg/ml and a dynamic range of 100 pg/ml – 100 ng/ml in human saliva. The developed biosensor is the first of its kind to utilize affinity-based detection through impedimetric measurements with a rapid detection time of less than a minute. Fourier transform infrared spectroscopy analysis confirmed the successful immobilization of the THC immobilization assay on the biosensing platform. Zeta potential studies provided information regarding the stability and the electrochemical behavior of THC immunoassay in varying salivary pH buffers. We have demonstrated stable, dose dependent biosensing in varying salivary pH’s. A binary classification system demonstrating a high general performance (AUC = 0.95) was employed to predict the presence of THC in human saliva. The biosensor on integration with low-power electronics and a portable saliva swab serves as a roadside DUI hand-held platform for rapid identification of THC in saliva samples obtained from human subjects.

Abstract
INTRODUCTION A priori power analysis is increasingly being recognized as a useful tool for designing efficient research studies that improve the probability of robust and publishable results. However, power analyses for many empirical designs in the addiction sciences require consideration of numerous parameters. Identifying appropriate parameter estimates is challenging due to multiple sources of uncertainty, which can limit power analyses' utility. METHOD We demonstrate a sensitivity analysis approach for systematically investigating the impact of various model parameters on power. We illustrate this approach using three design aspects of importance for substance use researchers conducting longitudinal studies base rates, individual differences (i.e., random slopes), and correlated predictors (e.g., co-use) and examine how sensitivity analyses can illuminate strategies for controlling power vulnerabilities in such parameters. RESULTS Even large numbers of participants and/or repeated assessments can be insufficient to observe associations when substance use base rates are too low or too high. Large individual differences can adversely affect power, even with increased assessments. Collinear predictors are rarely detrimental unless the correlation is high. CONCLUSIONS Increasing participants is usually more effective at buffering power than increasing assessments. Research designs can often enhance power by assessing participants twice as frequently as substance use occurs. Heterogeneity should be carefully estimated or empirically controlled, whereas collinearity infrequently impacts power significantly. Sensitivity analyses can identify regions of model parameter spaces that are vulnerable to bad guesses or sampling variability. These insights can be used to design robust studies that make optimal use of limited resources.

Abstract
OBJECTIVE The main objective of this study was to establish the blood alcohol concentrations (BACs) of bar patrons relative to the legal (BAC) limit for Ghana and the international guideline on alcohol consumption. METHOD A cross-sectional study design and a convenience sampling technique were used to collect data at selected bars in 2 cities, namely; Bolgatanga and Wa, in northern Ghana. A breathalyzer was used to measure the breath alcohol concentrations of participants exiting bars and face-to-face questionnaires were administered to participants to capture their accident histories, alcohol consumption patterns, and modes of transport they usually use to travel to their next destination after alcohol consumption. RESULTS The mean BAC of bar patrons was 0.143 ± 0.096% (95% confidence interval, 0.127 to 0.160%). The mean BAC of males (0.156%) was significantly higher than the mean BAC of females (0.103%; p = 0.004). Sixty-two percent of participants were exiting the bars with BACs of more than the legal BAC limit and 44% of this proportion was at 0.150% or more. Fifty-one percent of participants indicated that they usually consume a mixture of alcoholic beverages consisting of homemade and factory-made drinks. Fifty-seven percent of participants who usually consume a mixture of drinks had BACs of 0.150% or above. Only 22% of females and 6% of males consume alcohol within their respective recommended low risk of 1 to 2 units and 1 to 4 units, respectively. A vast majority of participants (96%) reported that they usually engage in risky behaviors such as riding, walking, or driving to their next destination after consuming alcohol. CONCLUSION Motorists were more likely to exit the bars with very high BACs. It is recommended that police should enforce the BAC law. In addition, in order to prevent harmful use of alcohol, the introduction of an alcohol consumption guideline in Ghana is recommended. Because alcohol consumption is increasing currently with motorization, it is also necessary to educate alcohol users about the number of drinks required to stay below the legal limit if they are motorists as well as other road users or to prevent long-term illnesses associated with excessive alcohol use.

Abstract
BACKGROUND Alcohol use is pervasive among motorists on the road in Ghana; however, we do not know the extent to which this behavior is implicated in road accidents in this country. OBJECTIVES The main objective of this research was to establish the prevalence of alcohol in the blood of nonfatally injured casualties in the emergency departments (EDs) in northern Ghana. METHOD Participants were injured road traffic crash victims, namely, pedestrians, cyclists, motorcyclists, and drivers seeking treatment at an ED. The study sites were 2 level III trauma centers located in Wa and Bolgatanga. Participants were screened for alcohol followed by breath tests for positive participants using breathalyzers. RESULTS Two hundred and sixty-two accident victims visited EDs, 58% of whom were in Wa. Among the victims, 41% were hospitalized and 57% experienced slight injuries. The vast majority (76%) of the casualties were motorcyclists, 13% were pedestrians, 8% were cyclists, and 2% were drivers. Casualties who had detectable alcohol in their blood were predominantly vulnerable road users. In all, 34% of participants had detectable blood alcohol concentrations (BACs) and the mean BAC for all casualties who tested positive and could give definitive BACs was 0.2265 (226 mg/dl). The prevalence of alcohol use was 53% among cyclists, 34% among motorcyclists, 21% among pedestrians, and 17% among drivers. Male casualties were more likely to test positive for alcohol than females. In addition, the prevalence of alcohol was significantly higher among injured casualties in Bolgatanga compared to Wa. CONCLUSION There was a high prevalence of alcohol use among nonfatally injured casualties in northern Ghana and injury severity increased with BAC. AUDIT screening in the hospital, alcohol consumption guideline, road safety education with an emphasis on minimizing or eliminating alcohol consumption, and enhanced enforcement of the BAC limit among motorists are recommended.

Abstract
BACKGROUND Traffic accidents and traffic-related injuries and mortality have become a major public health concern in Iran. This study aimed to examine the role of drug and alcohol use in motor vehicle accidents in Iran. METHODS This case-crossover study was conducted on 441 drivers who survived a road traffic crash and were taken to the emergency department of Shahid Rajaee trauma hospital in Shiraz, southern Iran. Data were collected using checklists that included demographic characteristics and drug and alcohol use prior to driving. Alcohol and drug use was identified through self-report, and cannabis, morphine, and methamphetamine urine tests were used to confirm drug abuse among drivers. RESULTS In total 17.9% of drivers reported using drugs (cannabis, opium, or metamphetamine) and 8.84% of drivers reported consuming alcohol prior to the collision. The crude odds ratios (ORs) for having a crash for opium, cannabis, and metamphetamine were 1.94 (95% interval confidence [CI], 1.11-3.38), 2.37 (95% CI, 1.03-5.42), 5.5 (95% CI, 1.21-24.81), respectively, and for all drugs was 3.83 (95% CI, 2.28-6.43). The OR for alcohol was 3.5 (95% CI, 1.73-7.06) based on self-report. CONCLUSION Drug and alcohol use are increasing the risk of traffic crashes in Iran. Risk-reducing programs must be designed and implemented.

Abstract
OBJECTIVES The main objective of this study was to establish the knowledge, attitudes, and practices toward drink driving/riding as a risk factor for road traffic crashes in 3 regional capitals in Ghana. METHODS The study used a face-to-face approach to randomly sample motorists who were accessing various services at fuel/gas stations, garages, and lorry terminals in 3 cities in Ghana. RESULTS Over the previous 12 months, 24% of all motorists and 55% of motorists who were current alcohol users reported driving or riding a vehicle within an hour of alcohol intake. On average, motorists/riders who were current alcohol users consumed 4 standard drinks per drinking occasion. Generally, 83% of motorists who currently use alcohol walked, rode, or drove home after consuming alcohol away from their homes. Motorists/riders who reported drink driving were 4 times more likely to have had previous traffic violation arrests compared to those who reported no drink driving/riding (P =.001). Respondents were of the opinion that speeding was the major cause of traffic crashes, followed by driver carelessness, poor road conditions, inexperienced driving, and drink driving, in that order. Thirty-six percent of motorists who use alcohol had the perception that consuming between 6 and 15 standard drinks was the volume of alcohol that will take them to the legal blood alcohol concentration (BAC) limit of 0.08%. Compared to females, male motorists/riders were more likely to report drink driving (adjusted odds ratio [AOR] = 5.15; 95% confidence interval [CI], 2.31 to 11.47). Private motorists also reported a higher likelihood of drink driving compared to commercial drivers (AOR = 3.36; 95% CI, 1.88 to 6.02). Only 4% of motorists knew the legal BAC limit of Ghana and only 2% had ever been tested for drink driving/riding. CONCLUSION The volumes of alcohol that motorists typically consume per drinking occasion were very high and their estimates of the number of drinks required to reach the legal BAC limit was also very high. Provision of authoritative information advising motorists about safe, responsible, or low-risk levels of alcohol consumption is imperative. Many traffic violations including drink driving were reported, thus suggesting a need for enhanced policing and enforcement. However, given the low level of knowledge of the legal BAC limit, educating motorists about how many drinks will approximate the legal BAC should be intensified prior to an increase in enforcement; otherwise, the desired outcome of enforcement may not be achieved.

Abstract
OBJECTIVE To determine whether preinjury health and injury-related factors were associated with posthospitalization discharge location and injury-associated complications for patients with blunt thoracic trauma. METHODS A retrospective analysis using registry data from a level 1 trauma center was conducted. A random sample of 200 patients admitted between 2009 and 2012 was included. Relationships between variables were assessed through cross-tabulation with the chi-square analysis; a P value <.05 was considered statistically significant. RESULTS Alcohol/drug use was related to hospital discharge location. Most patients with alcohol involved injuries discharged to locations other than home or long-term care facilities. Of the 59 patients who required intensive care, their length of stay was less than 3 days, and 24 required mechanical ventilation for short periods. Most blunt thoracic trauma patients were hospitalized less than 7 days. A relationship was identified between discharge location and the presence of any of the National Trauma Databank comorbid conditions and the comorbid condition of bleeding. A relationship between rib fractures and injury-associated complications was not found. The complication of pneumonia was related to length of stay and primary payment method. CONCLUSION Comorbid medical conditions and injury-related factors were associated with injury-related complications and discharge location for select variables. Further exploration with is needed to elucidate the associations more fully.

Abstract
Alcohol consumption with psychostimulants is very common among drug addicts. There is little known about the possible pharmacological interactions between alcohol and psychostimulants. Among most commonly co-abused psychostimulants with alcohol are methamphetamine, cocaine, 3,4-methylenedioxymethamphetaminen, and nicotine. Co-abuse of alcohol with psychostimulants can lead to several neurophysiological dysfunctions such as decrease in brain antioxidant enzymes, disruption of learning and memory processes, cerebral hypo-perfusion, neurotransmitters depletion as well as potentiation of drug seeking behaviour. Moreover, co-abuse of alcohol and psychostimulants can lead to increase in heart rate, blood pressure, myocardial oxygen consumption and cellular stress, and the risk of developing different types of cancer. Co-abuse of alcohol with psychostimulants during pregnancy can lead to fetal brain abnormalities. Further studies are needed to investigate the pharmacokinetics, pharmacodynamics, and neurochemical changes on co-abuse of alcohol and psychostimulants.

Abstract
Background Methamphetamine has an adverse effect on the ability to drive safely. Police need to quickly screen potentially impaired drivers therefore a rapid disposable test for methamphetamine is highly desirable. This is the first proof-of-concept report of a disposable electrochemical test for methamphetamine in undiluted saliva. Results A screen printed carbon electrode is used for the N,N′-(1,4-phenylene)-dibenzenesulfonamide mediated detection of methamphetamine in saliva buffer and saliva. The oxidized mediator reacts with methamphetamine to give an electrochemically active adduct which can undergo electrochemical reduction. Galvanostatic oxidation in combination with a double square wave reduction technique resulted in detection of methamphetamine in undiluted saliva with a response time of 55 s and lower detection limit of 400 ng/mL. Conclusions Using a double square wave voltammetry technique, rapid detection of methamphetamine in undiluted saliva can be achieved, however there is significant donor variation in response and the detection limit is significantly higher than desired. Further optimization of the assay and sensor format is required to improve the detection limit and reduce donor effects.

Abstract
Background Cannabis has an adverse effect on the ability to drive safely, therefore a rapid disposable test for Δ9-tetrahydrocannabinol (Δ9-THC), the psychoactive component of cannabis, is highly desirable for roadside testing. Results A screen printed carbon electrode is used for the N-(4-amino-3-methoxyphenyl)-methanesulfonamide mediated detection of Δ9-THC in saliva. Mediator placed in an overlayer was galvanostatically oxidized and reacted with Δ9-THC to give an electrochemically active adduct which could be detected by chronoamperometric reduction. Detection of 25-50 ng/mL Δ9-THC spiked into undiluted saliva was achieved with a response time of 30 s. A trial of the sensors with four cannabis smokers showed sensitivity of 28 %, specificity of 99 % and accuracy of 52 %. Conclusions Rapid electrochemical detection of Δ9-THC in undiluted saliva has been demonstrated using a disposable sensor, however the sensitivity is lower than acceptable. Further optimization of the assay and sensor format is required to improve the sensitivity of response to Δ9-THC.

Abstract
Impaired driving due to drug use is a growing problem worldwide; estimates show that 18-23.5% of fatal accidents, and up to 34% of injury accidents may be caused by drivers under the influence of drugs (Drummer et al., 2003; Walsh et al., 2004; NHTSA, 2010). Furthermore, at any given time, up to 16% of drivers may be using drugs that can impair one's driving abilities (NHTSA, 2009). Currently, drug recognition experts (DREs; law enforcement officers with specialized training to identify drugged driving), have the most difficult time with identifying drivers potentially impaired on central nervous system (CNS) depressants (Smith et al., 2002). The fact that the use of benzodiazepines, a type of CNS depressant, is also associated with the greatest likelihood of causing accidents (Dassanayake et al., 2011), further emphasizes the need to improve research tools in this area which can facilitate the refinement of, or additions to, current assessments of impaired driving. Our laboratories collaborated to evaluate both the behavioral and neurophysiological effects of a benzodiazepine, alprazolam, in a driving simulation (miniSim(TM)). This drive was combined with a neurocognitive assessment utilizing time synched neurophysiology (electroencephalography, ECG). While the behavioral effects of benzodiazepines are well characterized (Rapoport et al., 2009), we hypothesized that, with the addition of real-time neurophysiology and the utilization of simulation and neurocognitive assessment, we could find objective assessments of drug impairment that could improve the detection capabilities of DREs. Our analyses revealed that (1) specific driving conditions were significantly more difficult for benzodiazepine impaired drivers and (2) the neurocognitive tasks' metrics were able to classify "impaired" vs. "unimpaired" with up to 80% accuracy based on lane position deviation and lane departures. While this work requires replication in larger studies, our results not only identified criteria that could potentially improve the identification of benzodiazepine intoxication by DREs, but also demonstrated the promise for future studies using this approach to improve upon current, real-world assessments of impaired driving.

Abstract
OBJECTIVE The objective of this study was to determine the roadside prevalence of alcohol-impaired driving among drivers and riders in northern Ghana. The study also verifies motorists' perceptions of their own alcohol use and knowledge of the legal blood alcohol concentration (BAC) limit in Ghana. METHOD With the assistance of police, systematic random sampling was used to collect data at roadblocks using a cross-sectional study design. Breathalyzers were used to screen whether motorists had detectable alcohol in their breath and follow-up breath tests were conducted to measure the actual breath alcohol levels among positive participants. RESULTS In all, 9.7% of the 789 participants had detectable alcohol, among whom 6% exceeded the legal BAC limit of 0.08%. The prevalence of alcohol-impaired driving/riding was highest among cyclists (10% of all cyclists breath-tested) followed by truck drivers (9%) and motorcyclists (7% of all motorcyclists breath-tested). The occurrence of a positive BAC among cyclists was about 8 times higher (odds ratio [OR] = 7.73; P < .001) and it was 2 times higher among motorcyclists (OR = 2.30; P = .039) compared to private car drivers. The likelihood for detecting a positive BAC among male motorists/riders was higher than that among females (OR = 1.67; P = .354). The odds for detecting a positive BAC among weekend motorists/riders was significantly higher than on weekdays (OR = 2.62; P = .001). CONCLUSION Alcohol-impaired driving/riding in Ghana is high by international standards. In order to attenuate the harmful effects of alcohol misuse such as alcohol-impaired driving/riding, there is the need to educate road users about how much alcohol they can consume and stay below the legal limit. The police should also initiate random breath testing to instill the deterrence of detection, certainty of apprehension and punishment, and severity and celerity of punishment among drink-driving motorists and riders.

Abstract
BACKGROUND Statistics show an increasing proportion of alcohol and drug use in drivers in more recent times throughout the world. It has been found that among the various human factors, alcohol consumption, using drugs and subsequent driving on the roads are major risk factors. Traffic regulations in India penalises drivers who drive beyond permissible alcohol limit of 30 mg%. Consumption of psychoactive drugs such as opioid, cannabis and benzodiazepines has been reported mainly among youngsters. Hardly any data is available in Indian context particularly from North-West Zone of India. STUDY OBJECTIVE To study the pattern of alcohol, opioid, cannabis and benzodiazepines use in injured drivers presenting to a designated trauma centre in Chandigarh zone of North-West India. MATERIALS AND METHODS Consenting injured drivers who presented to the trauma centre in Chandigarh from September 2013 to January 2014 were included. Urine samples collected from the subjects were screened for abusive drug exposure (opioid, cannabis and benzodiazepines) and alcohol using commercial bedside urine immunoassay kits. In urine alcohol positive cases blood samples were collected and analysed for alcohol concentration using standard gas chromatography. Retrograde extrapolation method was used to assess BAC at the time of accident. RESULTS A total of 200 injured drivers were included in this study. We found substance consumption in 54.5% of drivers and alcohol (40.5%) was the most prevalent substance consumed followed by opiates (13%), cannabis (7%) and benzodiazepines (7%). More than one substance was shown in urine of 11.5% of drivers. Among 81 alcohol positive screening cases, the quantitative analysis was successfully done for 76 cases. Except one, all cases showed BAC value more than 30 mg% which is the legal limit for driving any vehicle in India. The values of alcohol concentration in blood at the time of accident were in the range of 20 to 391 mg%. CONCLUSION This study has shown that drivers are consuming not only alcohol but other psychoactive drugs also. Indian traffic regulatory authorities are penalising drunk drivers by doing road side breath alcohol testing with no protocols for drug screening. Appropriate measures should be adopted to screen traffic offenders for psychoactive drugs also.

Abstract
INTRODUCTION Emergency department (ED) visits resulting from motor vehicle crashes (MVCs) among individuals younger than 21 impaired by alcohol and/or drugs have been less studied than MVC fatalities. METHOD Using data from 2004 to 2011, we compare the magnitude and pattern of national ED visit and mortality data for alcohol- and drug-impaired youths involved in MVCs. RESULTS Temporal patterns of ED visits are similar to those of fatalities, but the two differ in magnitude. The ratio of ED visits to fatalities is 3.5:1; alcohol related events involvement dominates other drugs in both categories. DISCUSSION The volume of injuries serious enough to warrant ED visits imposes significant health, social, and financial burdens. In ED visits, alcohol is the prime source of MVC morbidity burden; other drugs consistently contribute less. PRACTICAL APPLICATIONS These incidents are persistent and require interventions aimed at multiple levels of prevention, including stricter corrective steps earlier in the impaired driving career to reduce subsequent incidents. ED visits for MVC injuries can be important "teachable moments." Limitations of the study indicate the need for improved surveillance of underage substance-involved crashes.

Abstract
BACKGROUND Patients with a history of substance misuse may develop tolerance to analgesics and psychotropic drugs which alter the need for sedation and analgesia after ICU admittance. AIMS The objective was to qualify and quantify the needs for sedation and analgesia in critically ill patients with and without a history of substance misuse admitted to an intensive care unit (ICU). DESIGN A 2-year prospective, observational study. METHODS Patients admitted to an ICU who required sedation and analgesia for ≥72 h were included and were classified as substance misusers and non-substance misusers. We analysed demographic data and the consumption of alcohol and other substances. Comparisons between groups were made using the non-parametric Mann-Whitney test for quantitative variables and Fisher's exact test for qualitative variables. The analysis was made using SPSS version 17.0 (SPSS Inc., Chicago, IL, USA) for Windows. Statistical significance was established as p < 0·05. RESULTS We included 44 patients, of whom 31 (70·3%) were users of ≥1 substance. The median age was 47 years, 8 (18·2%) patients were female. The most-consumed substances were tobacco (56·8%), alcohol (54·5%), cannabis (13·6%), amphetamines (11·4%) and cocaine (9·1%). Toxicological samples were positive for alcohol (65·2%, mean blood alcohol level 1·38 ± 1·05 g/L). There were no significant differences in the need for sedation between substance misusers and non-substance misusers (p > 0·05). CONCLUSIONS The prevalence of substance misuse in this population was high. We found no greater need for sedation in patients with a history of substance misuse although these patients often require three or more drugs to achieve optimal sedation. RELEVANCE TO CLINICAL PRACTICE Physicians and nurses should be aware of substance misuse in order to provide adequate care by optimizing drug administration and dosages in the ICU.

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.

Front Psychiatry 2014; 5:69. [PMID: 25221521 PMCID: PMC4148638 DOI: 10.3389/fpsyt.2014.00069] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2013] [Accepted: 05/31/2014] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Although the problem of substance use among drivers is not limited to certain parts of the world, most epidemiological reports on this topic have been published from industrial world. AIM To investigate pattern of drug use among Iranian drivers who were involved in fatal road accidents. METHODS This study enrolled 51 Iranian adults who were involved in fatal vehicle accidents and were imprisoned thereafter. Data came from a national survey of drug abuse that was done among Iranian prisoners. The survey collected data at the entry to seven prisons in different regions of the country during a 4-month period in 2008. Self-reported lifetime, last year, and last month drug use was measured. Commercial substance screening tests were applied to detect recent substance use (opioids, cannabinoids, methamphetamines, and benzodiazepines). RESULTS The commercial substance screening test showed three distinct patterns of recent illicit drug use: opioids (37.3%), cannabinoids (2.0%), opioids and cannabinoids (13.7%). 29.4% were also positive for benzodiazepines. The substance use screening test detected 23.5% of participants who had used drugs but did not disclose any substance use. CONCLUSION Opioids are the most common illicit drugs being used by Iranian drivers who are involved in fatal car accidents. The high rate of substance use prior to fatal car accidents in Iran advocates for the need for drug use control policies and programs as major strategies for injury prevention in Iran. There is also a need for substance screening among all drivers involved in fatal car accidents in Iran, as more than 20% of users may not disclose substance use.

Abstract
Oral fluid (OF) is a new biological matrix for clinical and forensic drug testing, offering non-invasive and directly observable sample collection reducing adulteration potential, ease of multiple sample collections, lower biohazard risk during collection, recent exposure identification, and stronger correlation with blood than urine concentrations. Because cannabinoids are usually the most prevalent analytes in illicit drug testing, application of OF drug testing requires sufficient scientific data to support sensitive and specific OF cannabinoid detection. This review presents current knowledge of OF cannabinoids, evaluating pharmacokinetic properties, detection windows, and correlation with other biological matrices and impairment from field applications and controlled drug administration studies. In addition, onsite screening technologies, confirmatory analytical methods, drug stability, and effects of sample collection procedure, adulterants, and passive environmental exposure are reviewed. Delta-9-tetrahydrocannabinol OF concentrations could be >1000 µg/L shortly after smoking, whereas minor cannabinoids are detected at 10-fold and metabolites at 1000-fold lower concentrations. OF research over the past decade demonstrated that appropriate interpretation of test results requires a comprehensive understanding of distinct elimination profiles and detection windows for different cannabinoids, which are influenced by administration route, dose, and drug use history. Thus, each drug testing program should establish cut-off criteria, collection/analysis procedures, and storage conditions tailored to its purposes. Building a scientific basis for OF testing is ongoing, with continuing OF cannabinoids research on passive environmental exposure, drug use history, donor physiological conditions, and oral cavity metabolism needed to better understand mechanisms of cannabinoid OF disposition and expand OF drug testing applicability. Published 2013. This article is a U.S. Government work and is in the public domain in the USA.

Abstract
OBJECTIVE Drug use by drivers is a significant and growing highway safety problem. College students are an important population to understand drugged driving. The objective of this study was to examine correlates of drugged driving among undergraduate college students. METHODS We conducted an anonymous, confidential, 24-question survey at a large New England public university during the 2010-2011 academic year among undergraduates in courses that met a graduation requirement. Data include demographics; academics; housing status; lifestyle; personal values; high school/college drug use; and driving following alcohol use, drug use, or both; and as a passenger with a driver who used alcohol, drugs, or both. Descriptive statistics were calculated. Chi-square tests compared driver alcohol use, drug use, or both with demographic, academic, and lifestyle variables. Logistic regression analyses were performed with drugged driving as the dependent variable. Odds ratios and corresponding 95 percent confidence intervals were calculated for each of the potential explanatory variables in relation to the outcome. RESULTS Four hundred forty-four of 675 students completed surveys (66% participation rate). Participants were representative of the student body with a mean age of 19.4 (±1.3 years), 51 percent male, 75 percent white, and 10 percent Hispanic. Seventy-eight percent lived on campus, 93 percent had a driver's license, and 37 percent had access to a car. Students disagreed that cannabinoids impair driving (18%) compared to other drugs (17%), stimulants (13%), depressants (11%), hallucinogens (8%), and alcohol (7%). Twenty-three percent drove after alcohol use and 22 percent drove after drug use. Forty-one percent reported having been a passenger with a driver who had been drinking and 37 percent with a driver using drugs. Drugged driving was more likely among males vs. females (30% vs. 14%, P < .01), those living off campus (34% vs. 19%, P < .01), those reporting that parties are important (33% vs. 14%, P < .01), those reporting that community service is not important (28% vs. 18%, P < .05), those reporting that religion is not important (28% vs. 14%, P < .01), and those reporting personal drug use in high school (75% vs. 14%, P < .01) and well as that their best friends used drugs in high school (42% vs. 12%, P < .01) and college (50% vs. 8%, P < .01). Those factors most associated with drugged driving included using drugs in high school (odds ratio [OR] = 9.5, 95% confidence interval [CI]: 4.6-19.6) and best friends in college used drugs regularly (OR = 6.2, 95% CI: 3.4-11.6). CONCLUSION Self-reported drugged driving and riding as a passenger with a drugged driver is common among subgroups of college students. The identification of undergraduate subgroups at risk for drugged driving will guide the design and implementation of traffic safety activities.

Abstract
BACKGROUND Drunk or drug-impaired drivers represent a major public health and societal problem worldwide. Because over 95% of drivers killed on the roads in Sweden are autopsied, reliable information is available about the use of alcohol and/or other drug before the crash. METHODS This retrospective 4-year study (2008-2011) used a forensic toxicology database (TOXBASE) to evaluate the concentrations of alcohol and other drugs in blood samples from drivers killed in road-traffic crashes. RESULTS The mean age of all victims (N = 895) was 48 ± 20 years, and the majority were male (86%). In 504 drivers (56%), the results of toxicological analysis were negative and these victims were older; mean age (± SD) 47 ± 20 years, than alcohol positive cases (35 ± 14 years) and illicit drug users (34 ± 15 years). In 21% of fatalities, blood-alcohol concentration (BAC) was above the statutory limit for driving (0.2 g/L), although the median BAC was appreciably higher (1.72 g/L). Illicit drugs (mainly amphetamine and cannabis) were identified in ~7% of victims, either alone (2.5%), together with alcohol (1.8%) or a prescription drug (2%). The psychoactive prescription drugs identified were mainly benzodiazepines, z-hypnotics and tramadol, which were found in the blood of 7.6% of crash victims. CONCLUSIONS The high median BAC in fatally-injured drivers speaks strongly towards alcohol-induced impairment as being responsible for the crash. Compared with alcohol, the prevalence of illicit and psychoactive prescription drugs was fairly low despite a dramatic increase in the number of drug-impaired drivers arrested by the police after a zero-tolerance law was introduced in 1999.

Abstract
Drugged driving is a serious safety concern, but its role in motor vehicle crashes has not been adequately studied. Using a case-control design, the authors assessed the association between drug use and fatal crash risk. Cases (n=737) were drivers who were involved in fatal motor vehicle crashes in the continental United States during specific time periods in 2007, and controls (n=7719) were participants of the 2007 National Roadside Survey of Alcohol and Drug Use by Drivers. Overall, 31.9% of the cases and 13.7% of the controls tested positive for at least one non-alcohol drug. The estimated odds ratios of fatal crash involvement associated with specific drug categories were 1.83 [95% confidence interval (CI): 1.39, 2.39] for marijuana, 3.03 (95% CI: 2.00, 4.48) for narcotics, 3.57 (95% CI: 2.63, 4.76) for stimulants, and 4.83 (95% CI: 3.18, 7.21) for depressants. Drivers who tested positive for both alcohol and drugs were at substantially heightened risk relative to those using neither alcohol nor drugs (Odds Ratio=23.24; 95% CI: 17.79, 30.28). These results indicate that drug use is associated with a significantly increased risk of fatal crash involvement, particularly when used in combination with alcohol.

Abstract
AIM To assess the epidemiological evidence associating the use of analgesics with the occurrence of road traffic crashes in senior drivers including a meta-analysis with specific focus on opioids. METHODS Systematic literature review of articles published between 1991 and 2012 retrieved from major databases using relevant key words. Eligible articles were fully reviewed and the main characteristics and results summarized. The methodological quality was assessed using the Newcastle-Ottawa Scale. Heterogeneity tests and forest and funnel plots were used as part of the meta-analysis on opioids. RESULTS From the potentially eligible articles, nine were selected (4 case-control, 1 case-crossover, and 4 cohort studies) of which four were of medium and five of high quality; seven investigated opioids and four non-steroidal anti-inflammatory drugs. Crash involvement (n=7) rather than responsibility (n=2) was investigated. Age and sex were the most common covariates adjusted for. Both opioids and non-steroidal anti-inflammatory drugs showed mixed results including differences across estimates between and within studies. A marginal positive effect was observed in the pooled analyses on opioids (n=6, OR 1.20; 95% CI 1.08-1.32). CONCLUSIONS The evidence is unconvincing in terms of number of studies, control of major confounders, and consistency of the results. The effect seen for opioids can be attributed to the lack of adjustment of key confounders such as concomitant illness or the consumption of alcohol or other psychoactive medications. There is a need for more efficient designs like larger population-based retrospective cohorts and nested case-control or case-crossover studies based on registers of high quality allowing adjustment for these factors and for the selection of unequivocal outcomes (e.g. drivers' responsibility) to produce more persuasive empirical evidence.

Abstract
BACKGROUND Cannabis is the most prevalent illicit drug identified in impaired drivers. The effects of cannabis on driving continue to be debated, making prosecution and legislation difficult. Historically, delays in sample collection, evaluating the inactive Δ(9)-tetrahydrocannabinol (THC) metabolite 11-nor-9-carboxy-THC, and polydrug use have complicated epidemiologic evaluations of driver impairment after cannabis use. CONTENT We review and evaluate the current literature on cannabis' effects on driving, highlighting the epidemiologic and experimental data. Epidemiologic data show that the risk of involvement in a motor vehicle accident (MVA) increases approximately 2-fold after cannabis smoking. The adjusted risk of driver culpability also increases substantially, particularly with increased blood THC concentrations. Studies that have used urine as the biological matrix have not shown an association between cannabis and crash risk. Experimental data show that drivers attempt to compensate by driving more slowly after smoking cannabis, but control deteriorates with increasing task complexity. Cannabis smoking increases lane weaving and impaired cognitive function. Critical-tracking tests, reaction times, divided-attention tasks, and lane-position variability all show cannabis-induced impairment. Despite purported tolerance in frequent smokers, complex tasks still show impairment. Combining cannabis with alcohol enhances impairment, especially lane weaving. SUMMARY Differences in study designs frequently account for inconsistencies in results between studies. Participant-selection bias and confounding factors attenuate ostensible cannabis effects, but the association with MVA often retains significance. Evidence suggests recent smoking and/or blood THC concentrations 2-5 ng/mL are associated with substantial driving impairment, particularly in occasional smokers. Future cannabis-and-driving research should emphasize challenging tasks, such as divided attention, and include occasional and chronic daily cannabis smokers.

Abstract
OBJECTIVE Prescription drug overdoses, abuse, and sales have increased dramatically in the United States in the last decade. The purpose of the present study was to link crash data with emergency department (ED) and inpatient hospitalization data to assess the concordance between the data sets in the identification of the presence of drugs among injured motor vehicle drivers (passenger cars, passenger trucks, light trucks, and semi-trucks) in Kentucky. METHODS Kentucky CRASH data were probabilistically linked to ED data sets for years 2008-2010 and to inpatient hospitalization data sets for years 2000-2010. Statistical analyses were performed. RESULTS Of the 72,529 linked crash/ED visits, there were 473 drivers with an associated nondependent abuse of drugs diagnosis in the ED, and 930 drivers had drug involvement recorded in the CRASH data (only 163 cases overlapped with drug involvement both recorded in CRASH data and coded as nondependent abuse of drugs in the ED); 64 drivers had multiple drug types present in their system. Of the 20,860 total linked crash/inpatient hospitalization cases, there were 973 drivers diagnosed with nondependent abuse of drugs in the inpatient hospitalization record and 499 drivers had drug involvement recorded in the CRASH data (only 207 overlapped); 250 drivers were diagnosed with multiple drugs in their system. CONCLUSIONS Surveillance data from multiple public health data sets is necessary to identify the presence of drugs in injured drivers involved in motor vehicle crashes. The use of a single surveillance data set alone may significantly underreport the number of drugged drivers who were injured in a motor vehicle collision.

Abstract
PURPOSE The use of small titanium plates for the management of mandibular fractures continues to be a source of controversy because of their load-sharing properties. The purpose of the present study was to determine whether the use of small plates for mandibular fractures is as efficacious as large plates in a large level I trauma center. MATERIALS AND METHODS Consecutive subjects presenting with mandibular fractures were randomly allocated to the use of either small plates (group 1) or large plates (group 2). The primary predictor variable was the plate size. The primary outcome variable was fracture union. The secondary outcomes included complications and operative time. Statistical analysis was performed using the Wilcoxon rank sum test for ordinal and continuous variables and the χ(2) test or Fisher exact test for proportions. RESULTS A total of 127 consecutive subjects with a fracture of the mandible were enrolled in the study. Of the 127 subjects, 53 completed the required follow-up of at least 6 weeks. There was no difference in the rate of fracture union between the 2 groups (P = .95). CONCLUSIONS The study findings suggest that the use of small plates and monocortical screws for mandibular fractures results in favorable outcomes compared with using larger plates and bicortical screws.

Abstract
Background The prevalence of alcohol and other psychoactive substances is high in biological specimens from injured drivers, while the prevalence of these psychoactive substances in samples from drivers in normal traffic is low. The aim of this study was to compare the prevalence of alcohol and psychoactive substances in drivers admitted to hospital for treatment of injuries after road traffic accidents with that in drivers in normal traffic, and calculate risk estimates for the substances, and combinations of substances found in both groups. Methods Injured drivers were recruited in the hospital emergency department and drivers in normal conditions were taken from the hospital catchment area in roadside tests of moving traffic. Substances found in blood samples from injured drivers and oral fluid samples from drivers in moving traffic were compared using equivalent cut off concentrations, and risk estimates were calculated using logistic regression analyses. Results In 21.9% of the injured drivers, substances were found: most commonly alcohol (11.5%) and stimulants eg. cocaine or amphetamines (9.4%). This compares to 3.2% of drivers in normal traffic where the most commonly found substances were z-hypnotics (0.9%) and benzodiazepines (0.8%). The greatest increase in risk of being injured was for alcohol combined with any other substance (OR: 231.9, 95% CI: 33.3- 1615.4, p < 0.001), for more than three psychoactive substances (OR: 38.9, 95% CI: 8.2- 185.0, p < 0.001) and for alcohol alone (OR: 36.1, 95% CI: 13.2- 98.6, p < 0.001). Single use of non-alcohol substances was not associated with increased accident risk. Conclusion The prevalence of psychoactive substances was higher among injured drivers than drivers in normal moving traffic. The risk of accident is greatly increased among drivers who tested positive for alcohol, in particular, those who had also ingested one or more psychoactive substances. Various preventive measures should be considered to curb the prevalence of driving under the influence of psychoactive substances as these drivers constitute a significant risk for other road users as well as themselves.

Abstract
Since 1996, 16 states and the District of Columbia in the United States have enacted legislation to decriminalize marijuana for medical use. Although marijuana is the most commonly detected nonalcohol drug in drivers, its role in crash causation remains unsettled. To assess the association between marijuana use and crash risk, the authors performed a meta-analysis of 9 epidemiologic studies published in English in the past 2 decades identified through a systematic search of bibliographic databases. Estimated odds ratios relating marijuana use to crash risk reported in these studies ranged from 0.85 to 7.16. Pooled analysis based on the random-effects model yielded a summary odds ratio of 2.66 (95% confidence interval: 2.07, 3.41). Analysis of individual studies indicated that the heightened risk of crash involvement associated with marijuana use persisted after adjustment for confounding variables and that the risk of crash involvement increased in a dose-response fashion with the concentration of 11-nor-9-carboxy-delta-9-tetrahydrocannabinol detected in the urine and the frequency of self-reported marijuana use. The results of this meta-analysis suggest that marijuana use by drivers is associated with a significantly increased risk of being involved in motor vehicle crashes.

Correlation between driving-related skill and alcohol use in young-adults from six European countries: the TEN-D by Night Project. BMC Public Health 2011; 11:526. [PMID: 21722358 PMCID: PMC3145590 DOI: 10.1186/1471-2458-11-526] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2010] [Accepted: 07/01/2011] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Only few studies with small experimental samples investigated the impact of psychoactive substances on driving performance. We conducted a multicenter international cross-sectional study to evaluate the correlation between alcohol use and driving-related skill as measured by brake reaction time (RT). METHODS Before and after the entrance into randomly selected recreational sites from six European countries, all subjects aged 16-35 years, owning a driver license, were asked to compile a structured socio-demographic questionnaire and measure RT (SimuNomad3 driving simulator), breath alcohol concentration (BAC; Drager Alcoltest), and drug use (Oratect III saliva test, only at the exit). Mixed regression modeling was used to evaluate the independent association between RT and alcohol concentration or drug use. RESULTS Before the entrance into the recreational site, 4534 subjects completed all assessments and composed the final sample. Their mean age was 23.1±4.2 y; 68.3% were males; 54.7% had BAC>0 g/L (assumed alcoholics); 7.5% declared illegal drug assumption (mostly cannabis). After the exit, 3019 also completed the second assessment: 71.7% showed BAC>0 g/L. Controlling for age, gender, educational level, occupation, driver license years, and drug use, BAC was positively associated with RT, achieving significance, however, only when BAC was higher than 0.49 g/L. Significant interaction terms were found between BAC and female gender or drug use, with highest RTs (>1 sec.) recorded among drug users with BAC>or=1 g/L. CONCLUSIONS This field study confirms previous experimental data on the negative impact of alcohol use on driving-related skill, supporting regulations and educational campaigns aimed at discouraging driving after consumption of psychoactive substances.

Dubois S, Bédard M, Weaver B. The association between opioid analgesics and unsafe driving actions preceding fatal crashes. ACCIDENT; ANALYSIS AND PREVENTION 2010; 42:30-37. [PMID: 19887141 DOI: 10.1016/j.aap.2009.06.030] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2008] [Revised: 06/18/2009] [Accepted: 06/30/2009] [Indexed: 05/28/2023]
Abstract
Currently, most epidemiological research into the impact of opioid analgesics on road safety has focused on the association between opioid use and traffic crash occurrence. Yet, the role of opioid analgesics on crash responsibility is still not properly understood. Therefore, we examined the impact of opioid analgesics on drivers (all had a confirmed BAC=0) involved in fatal crashes (1993-2006) using a case-control design based on data from the Fatality Analysis Reporting System. Cases had one or more crash-related unsafe driving actions (UDA) recorded; controls had none. We calculated adjusted odds ratios (ORs) of any UDA by medication exposure after controlling for age, sex, other medications, and driving record. Compared to drivers who tested negative for opioid analgesics, female drivers who tested positive demonstrated increased odds of performing an UDA from ages 25 (OR: 1.35; 95% CI: 1.05; 1.74) to 55 (OR: 1.30; 95% CI: 1.07; 1.58). For male drivers this was true from ages 25 (OR: 1.66; 95% CI: 1.32; 2.09) to 65 (OR: 1.39; 95% CI: 1.17; 1.67). The detection of opioid analgesics was not associated with greater risk of an UDA for older drivers. Research is necessary to examine why these age differences exist, and if possible, to ensure that opioid analgesics do not contribute to crashes.

Abstract
OBJECTIVE To determine characteristics of a nationwide sample of Iranian dependent drug users whose main profession is driving. METHODS Data were derived from a larger study, which aimed to describe pattern of drug dependency in Iran. A "driver" was defined as a person whose main profession was driving a motor vehicle to earn a living. Nine hundred twenty individuals were interviewed by a trained drug abuse team in all provinces of Iran during a 5-month period, from April to August 2007. Socioeconomic characteristics, substance abused, and high-risk behaviors were collected by a checklist. RESULTS All drivers were male and their mean (+/- standard deviation) age was 35.1 (+/- 8.6) years. Opioids (434 cases, 46.8%) and kerack (256 cases, 27.6%) were the two most common drugs used. Except for buprenorphine, which was used via intravenous injection, inhalation was the dominant method of us in other substances including opioids (56%), heroin (51.4%), kerack (80.1%), methamphetamine (73.9%), and cannabis (77.8%). Extramarital sexual relationships (414 cases, 45%) and nonfatal intoxication (362 cases, 39.3%) were the two most frequent high-risk behaviors. CONCLUSIONS There are people with drug dependencies who drive for living in Iran. Deterrence programs through screening and random drug testing at police stations and legislation regarding charges of drugged drivers and prohibition from driving for long time periods are essential priorities in traffic safety.

Abstract
Alcohol and other substance abuse that alters behavior make up the principal risk factor to suffer serious traumas. Patients who have had an alcohol or other drug consumption related accident have a high risk of recidivism. Currently, no efforts are spared to achieve the physical recovery of these patients. However, on the contrary to other diseases, the efforts aimed at preventing recidivism (secondary prevention) are practically null. A brief psychological intervention made during the bedridden period may modify the behavior and decrease the risk of new accidents. Therefore, establishing secondary prevention programs should be considered a priority objective in sites that receive traumatized patients.

Abstract
Alcohol is one of the main causes of traffic accidents worldwide. Its use decreases significantly the driving ability of an individual increasing in this way the possibilities of their involvement in motor-vehicle accidents. The above possibilities are increased when a psychoactive substance has been taken in combination with alcohol due to their synergistic effect. The Laboratory of Forensic Medicine and Toxicology of the University of Athens is authorized to perform the toxicological investigation of traffic accidents that happen in the southern part of Greece. The objective of the present study was to identify the prevalence of alcohol and other psychoactive substances among drivers involved in road traffic accidents in Greece during the period 1998-2004. Alcohol was detected in the blood of about 37% of the drivers involved in traffic accident during the years 1998-2000. The detection of alcohol was lower (29%) in the years 2001-2004. Cannabis, benzodiazepines, opiates, and cocaine were found in 4%, 4%, 4% and 1% of the total number of cases, respectively. The above values were compared with those of a previous study concerning the period 1995-1997 and the reasons for the reduction of the number of alcohol-related traffic accidents during the last years are discussed.

Abstract
Cocaine and its major metabolite benzoylecgonine (BZE) were determined in blood samples from people arrested in Sweden for driving under the influence of drugs (DUID) over a 5-year period (2000-2004). Venous blood or urine if available, was subjected to a broad toxicological screening analysis for cannabis, cocaine metabolite, amphetamines, opiates and the major benzodiazepines. Verification and quantitative analysis of cocaine and BZE in blood was done by gas chromatography-mass spectrometry (GC-MS) at limits of quantitation (LOQ) of 0.02mg/L for both substances. Over the study period 26,567 blood samples were analyzed and cocaine and/or BZE were verified in 795 cases (3%). The motorists using cocaine were predominantly men (>96%) with an average age of 28.3+/-7.1 years (+/-standard deviation, S.D.). The concentration of cocaine was below LOQ in 574 cases although BZE was determined at mean, median and highest concentrations of 0.19mg/L, 0.12mg/L and 1.3mg/L, respectively. In 221 cases, cocaine and BZE were together in the blood samples at mean and (median) concentrations of 0.076mg/L (0.05mg/L) and 0.859mg/L (0.70mg/L), respectively. The concentrations of BZE were always higher than the parent drug; mean BZE/cocaine ratio 14.2 (median 10.9) range 1-55. Cocaine and BZE were the only psychoactive substances reported in N=61 cases at mean (median) and highest concentrations of 0.095 (0.07) and 0.5mg/L for cocaine and 1.01 (0.70) and 3.1mg/L for BZE. Typical signs of drug influence noted by the arresting police officers included bloodshot and glossy eyes, agitation, difficulty in sitting still and incoherent speech.

Abstract
A current perspective of workplace drug testing in the USA is presented covering three major issue areas: (1) epidemiology, (2) new technology and (3) initiatives to reach out and assist small business. First, national illegal drug-use self-reported survey data is compared with national laboratory drug testing results, illustrating a number of inconsistencies. During the 17-year period (1988-2004) the number of laboratory positive test results has decreased by 66% while during the same period self-reported drug-use has increased by 30%. The lack of concurrence between lab results and self-report surveys are examined in light of the typical panel of drugs being tested in U.S. laboratories, the increased specificity of immunoassay screening tests, and the critical issues of adulteration and substitution. Second, a brief review of the state-of-the-science in rapid point-of-collection (POCT) oral fluid drug-testing devices is presented along with some device evaluation findings. In general the window of drug detection in oral fluid is measured in hours. Most of the available oral fluid POCT devices can detect methamphetamine and amphetamines and opiates very well. The ability to detect cocaine appears to vary significantly across devices, while the ability to detect cannabis use is generally poor across all devices. Finally, efforts to reach out and assist small businesses in the development of workplace anti-drug programs are discussed in the context of increasing workplace programs in the European Union.

Abstract
BACKGROUND Abrupt cessation of chronic drinking patterns places hospitalized patients at risk for alcohol withdrawal syndrome (AWS). The purpose of this study was to investigate the effect of AWS on length of stay, morbidity, mortality, and cost in low injury acuity trauma patients. METHODS A retrospective review of the National Trauma Registry of the American College of Surgeons database from July 1999 to February 2004 was performed. All patients 15 years or older admitted to our Level I trauma center with an Injury Severity Score (ISS) <16 were included. AWS patients were compared with those without AWS. Demographics, mechanism of injury (MOI), ISS, revised trauma score, Glasgow Coma score, hospital course, morbidity, requirement of additional procedures, mortality, and cost were compared. Analysis was done with chi2 test and Student's t test. A p value of < or =0.05 determined significance. RESULTS Of 6,431 patients, 55 (0.9%) developed AWS. AWS patients were likely men (p < 0.001); had a higher ISS (p = 0.001) and lower Glasgow Coma score (p = 0.01); had more ventilator days (p = 0.008), intensive care unit days (p < 0.0001), and hospital days (p < 0.0001); suffered more complications, including respiratory failure (p < 0.0001), pneumonia (p < 0.0001), urinary tract infection (p = 0.0005), sepsis (p < 0.0001), tracheostomy (p < 0.0001), and percutaneous endoscopic gastrostomy (p < 0.0001); and had higher cost (p < 0.0001). Mortality was similar (p = 0.38) among groups. CONCLUSIONS Low injury acuity patients with AWS have increased morbidity, leading to increased hospital stay and cost. To allow minor injuries to remain minor problems, the best modality to identify patients at risk and to achieve AWS prophylaxis require further investigation.

Abstract
BACKGROUND Use of alcohol and illicit drugs by adolescents remains a problem in the U.S. Case identification and early treatment can occur within a broad variety of healthcare and non-healthcare settings, including acute care hospitals. The objective of this study is to describe the extent and nature of adolescent admissions to the acute inpatient setting for substance abuse (SA). We use the Agency for Healthcare Research and Quality (AHRQ) 2000 Healthcare Cost and Utilization Project Kids Inpatient Database (HCUP-KID) which includes over 2.5 million admissions for youth age 20 and under to 2,784 hospitals in 27 states in the year 2000. Specifically, this analysis estimates national number of admissions, mean total charges, and mean lengths of stay for adolescents between the ages of 12 and 17 admitted to an acute care hospital for the following diagnostic categories from the AHRQ's Clinical Classifications Software categories: "alcohol-related mental disorders" and "substance-related mental disorders". Frequency and percentage of total admissions were calculated for demographic variables of age, gender and income and for hospital characteristic variables of urban/rural designation and children's hospital designation. RESULTS SA admissions represented 1.25 percent of adolescent admissions to acute care hospitals. Nearly 90 percent of the admission occurred in non-Children's hospitals. Most were for drug dependence (38%) or non-dependent use of alcohol or drugs (35%). Costs were highest for drug dependence admissions. Nearly half of admissions had comorbid mental health diagnoses. Higher rates of admission were seen in boys, in older adolescents, and in "self-pay" patients. Alcohol and drug rehabilitation/detoxification, alone or in combination with psychological and psychiatric evaluation and therapy, was documented for 38 percent of admissions. Over 50 percent of cases had no documentation of treatment specific to substance use behavior. CONCLUSION General acute care hospitals have a significant and important opportunity to recognize, treat, and refer adolescents with substance abuse problems. These results suggest that inpatient facilities should develop and implement policies and processes to ensure that adolescent substance abusers admitted to their institutions receive appropriate care during the admission and appropriate referral to community care resources.
