Aims: To describe the prevalence of recent use of alcohol, medication, and illegal drugs among patients who attended emergency departments (EDs) as a result of suffering an injury due to any external mechanism and to identify factors associated with alcohol and drug use. Methods: A cross-sectional study was conducted in eight university hospitals in Spain. Participants were adult patients admitted to a trauma ED. Oral fluid was used to test for psychoactive substances analyzed by gas chromatography-mass spectrometry. Socio-demographic data and information on circumstances of the injury were collected through interviews. Results: The analysis included 1579 patients admitted to the EDs (56.4% men). Among Young people (= 40 years, 7.4% of men and 1.6% of women were positive for any illegal substance, and 16.3% and 11.0% respectively for alcohol. Prevalence of substance detected varied across mechanism of injury, gender and age group. Night-time injury was associated with substance use. Conclusions: A high proportion of injured patients who were treated in an EDs tested positive for psychoactive drugs. Routine testing at trauma departments would maximize the identification of patients who may benefit from referral to specialized addiction treatment centers, or brief interventions.

Objective: To describe the prevalence of recent psychoactive substance use and associated factors among road traffic casualties admitted to emergency departments. Methods: A cross-sectional study was carried out, including adults injured in road traffic crashes admitted to the emergency department (ED) of eight hospitals in Catalonia (Spain), during three cross-sections, each of 4 days duration (2005-2006). Information sources were an interview, an oral fluid specimen and the patient's clinical record. Dependent variables were presence of alcohol, cannabis, cocaine, ecstasy, opiates or benzodiazepines. Independent variables were socioeconomic characteristics and circumstances of the injuries and admission. Prevalence and exact 95% confidence intervals were estimated for men and women. Bivariate analyses and multivariate binomial regression modelling were carried out to study factors associated with substance use in male drivers and pedestrians. Results: The prevalence of substance use was higher in men (n = 226) than in women (n = 161) for any substance (34.4% and 16.2%), any illegal substance (19.3% and 7.6%), alcohol (18.5% and 9.2%) and cannabis (17.0% and 3.8%), respectively. In male drivers and pedestrians, alcohol use was associated with being in the 25-30-year age group, being injured at night and the weekend, and arriving at the ED by ambulance; cannabis use was only associated with being in the 18-30-year age group. Conclusions: A high prevalence of recent psychoactive substance use, especially alcohol, cannabis and cocaine, was observed in all age groups. The results indicate the need to screen for substance use and to give simple advice to casualties at EDs.

The objective is to describe injuries of road traffic deaths in Barcelona and identify injury profiles by road user type, through a cross-sectional study including road traffic deaths for the period 1997–2004. The data source was the Institut de Medicina Legal de Catalunya. Diagnoses were coded using the International Classification of Diseases, 9th revision, Clinical Modification, and classified using the Barell Matrix. Of the 719 deaths studied, 45% were pedestrians, 32% two wheel motor vehicle users, and 23% car occupants. The injury profile of the road traffic deaths in Barcelona is internal injuries and fractures to the torso and to the head/neck. This profile is repeated in all the road user groups, although pedestrians present higher frequencies of fractures and contusions to extremities and contusions to the head/neck, and fewer internal torso injuries than car occupants or two wheel motor vehicle users.
