Incidence trends of traumatic spinal cord injury and traumatic brain injury in Spain, 2000-2009

AIMS The aim of the present study was to estimate the incidence of hospital discharges for traumatic spinal cord injury (TSCI) and traumatic brain injury (TBI) in Spain by injury circumstances (traffic crashes and others), injury severity, gender and age group and to describe its trends over the period 2000-2009. METHODS It is a study of trends that includes hospital discharges with a primary diagnosis of TSCI or TBI. Crude and age-standardised rates were calculated per million inhabitants. Changes in rates between 2000 and 2009 were assessed through calculation of the relative risk adjusted for age, using Poisson regression. RESULTS Between 2000 and 2009 in Spain, 10,274 patients were admitted for traumatic TSCI, and 206,503 for TBI. The annual incidence rate for TSCI was 23.5 per million, that for TBI was 472.6 per million. The overall incidence rate for TSCI fell significantly between 2000 and 2009 by 24.2% (traffic-related 40.9%, other 12.9%), as did that for TBI (23.8% overall, 60.2% traffic-related, with no change for other circumstances). Among people aged 65 years and over, no change was observed for TSCI, incidence of TBI fell significantly when due to traffic crashes, but there was a dramatic increase of 87% in men and 89.3% in women when due to other circumstances. CONCLUSIONS Over the last decade the incidence of these types of injury has fallen significantly when the injury resulted from traffic crashes, and to a lesser extent when from other circumstances. However TBI incidence among people aged 65 and over injured in non-traffic-related circumstances has risen dramatically.

Substance use among road traffic casualties admitted to emergency departments

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.

Psychometric properties of the CAST and SDS scales in young adult cannabis users

AIM To assess the validity of two cannabis use severity scales among young cannabis users and to evaluate their ability to detect Substance Use Disorders (SUD). PARTICIPANTS 241 volunteers (18-25 years), with a wide spectrum of cannabis use in the last 12 months. MEASUREMENTS The Cannabis Abuse Screening Test (CAST) and Severity of Dependence Scale (SDS) were self-administered. The Psychiatric Interview for Substance and Mental Disorders (PRISM) was used as gold standard for cannabis use disorders according to DSM-IV. Reliability and validity were assessed for two different CAST coding algorithms (b-binary and f-full) and for the SDS. In addition, the cannabis use diagnostic criteria contained in the PRISM were grouped to approximate forthcoming proposed DSM-V criteria to further evaluate these scales. FINDINGS 26.6% (95% CI: 21.0-32.2) of the subjects met criteria for cannabis dependence, and 49.0% (95% CI: 42.7-55.3) for cannabis use disorders. For both scales internal consistency (Cronbachs alpha>0.71) and test-retest intraclass correlation coefficients (>0.80) were good. The score 12 in the CAST-full discriminated better than others between presence and absence of dependence (27.0%; 95% CI: 21.4-32.6) while the score for discrimination of SUD was 9 (51.5%; 95% CI: 45.1-57.8). For the SDS the values were 7 (22.0%; 95% CI: 16.8-27.2) and 3 (64.7%; 95% CI: 58.7-70.8), respectively. According to proposed DSM-V criteria, for moderate and severe addiction the values for the CAST-f were 7 (68.5%; 95% CI: 62.5-74.3) and 12 (27%; 95% CI: 21.3-32.6) and for the SDS, 3 (65.0%; 95% CI: 58.7-70.8) and 7 (22%; 95% CI: 17.0-34.3), respectively. CONCLUSIONS The CAST and SDS applied to young cannabis users are reliable and valid measures to detect cannabis use disorders when compared to both DSM-IV and proposed DSM-V criteria.

Spinal cord injury and traumatic brain injury: a cost-of-illness study

Background: Among traumatic injuries, spinal cord injuries (SCI) and traumatic brain injuries (TBI) are of major importance because of their epidemiological and economic impact on society. The overall objective of this study was to estimate the economic cost associated with people with SCI and TBI in Spain in 2007. Methods: A cost-of-illness analysis was performed, considering the perspective of society, using a 1-year time horizon. Medical costs, adaptation costs, material costs, administrative costs, and costs of police, firefighters and roadside assistance, productivity losses due to institutionalization and sick leave, as well as an estimate of productivity losses of carers, and productivity losses due to death were included. Results: The economic cost associated with people with SCI is between EUR 92,087,080.97 and 212,496,196.41 (USD 131 million and 302 million) according to the injury mechanism, and between EUR 1,079,223,688.66 and 3,833,752,692.78 (USD 1,536 million and 5,458 million) for people with TBI. Conclusions: There is an urgent need to develop effective interventions known to prevent SCI and TBI, and to evaluate their effectiveness and efficiency.

Lesiones por caídas y factores asociados en personas mayores de Cataluña, España

OBJECTIVES To assess, based on a population health survey, what proportion of individuals in a sample of non-institutionalized older persons suffered injuries from unintentional falls, and to evaluate the associated demographic and health-related factors. METHODS A total of 3,247 individuals over 65 years of age, selected by multistage random sampling, participated in the Health Survey of Cataluña (ESCA-2006), answering an interviewer-administered questionnaire that included questions about injuries from falls, and any relevant associated factors, during the 12 months preceding the survey. RESULTS Of the respondents, 14.9% reported having been injured by falling. Multivariate analysis indicated that sex, age, living alone, taking five or more medications, and suffering from mobility problems, diabetes, or musculoskeletal disorders were associated with an increased risk of injury from falls. However, no statistically significant effect was observed from sensory or communication impairment, cardiovascular disease, cataracts, or alcohol consumption. CONCLUSIONS Health care services, which are often in contact with the elderly, can identify those who are at increased risk of falling and put into place a variety of proven, preventive interventions. Though somewhat limited, population health surveys provide useful information regarding the burden of fall-related injuries on elderly health and complement data provided by other sources.

Substance use among non-fatally injured patients attended at emergency departments in Spain

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), 21.4% of men and 8.5% of women were positive for any illegal substance, primarily cannabinoids or cocaine; 24.7% of men and 14.8% of women were positive for alcohol. Among patients > or = 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.

La proyección social y sanitaria de los Institutos de Medicina Legal en España: más allá de la justicia

The main mission of Spanish Institutes of Legal Medicine (ILMs) is to serve the justice system. We review the potential broader role of the work done by ILMs, with an emphasis on forensic pathology. The relevance of forensic information to increase the quality of mortality statistics is highlighted, taking into account the persistence of the low validity of the external causes of death in the Mortality Register that was already detected more than a decade ago. The new statistical form and reporting system for the deaths under ILMs jurisdiction, as introduced by the Spanish Instituto Nacional de Estadística in 2009, are also described. The IMLs role in the investigation of the following mortality causes and of their determinants is reviewed in detail: traffic accidents, suicide, drugs of abuse, child deaths and sudden deaths. We conclude that an important public role of IMLs is emerging beyond their valuable service to the justice system, mainly through the gathering of data critical to assess and prevent several medical and public health and safety issues of great social impact and through their participation in epidemiologic research and surveillance.The main mission of Spanish Institutes of Legal Medicine (ILMs) is to serve the justice system.

Violencia del compañero íntimo contra la mujer: una mirada desde la Salud Pública

Resumen La violencia del companero intimo (VCI) es la forma mas frecuente de violencia contra las mujeres, y causa fallecimientos, lesiones, danos psicologicos y discapacidad. En Espana, la mortalidad por VCI parece relativamente estable, pero el 15% de las mujeres visitadas por medicos de familia y el 10% de las mayores de 18 anos la han padecido. Ser inmigrante, mayor, separada o divorciada, con un bajo nivel educativo o de ingresos, y bajo apoyo social se asocian con haber sufrido VCI. La VCI es el resultado de una constelacion de determinantes individuales, interpersonales, comunitarios y sociales. Las estrategias de prevencion efectivas incluyen intervenciones dirigidas a bebedores problematicos, programas escolares de modifi cacion de las normas y actitudes con respecto al sexo y programas de apoyo a las organizaciones sociales. La salud publica puede tener un papel valioso colaborando activamente en la prevencion y el control de la violencia del companero intimo.Intimate partner violence (IPV), an intentional use of physical force or power against a partner, is the most common form of violence against women, and frequently results in injuries, death, psychological harm and disability. In Spain, mortality due to IPV is fairly stable, but around 15% of women visited by family doctors and 10% of those aged 18 or above, have experienced some form of IPV within the previous year. Being immigrant, older, separated or divorced, with low education or incomes, and low social support are associated with a history of IPV. IPV is the result of a multitude of individual, interpersonal, community and social determining factors. Interventions for problem drinkers, school-based programmes to address gender norms and attitudes, and social support programmes are effective strategies to prevent IPV. The Public Health sector may have a valuable role by actively collaborating in the prevention and control of intimate partner violence

Internet Use and Suicidal Behaviors: Internet as a Threat or Opportunity?

BACKGROUND Suicidal behavior is a common and severe health problem around the world. Internet use has been related to an increase in suicidal behaviors, but few studies have focused on the potential benefits of Internet use for preventing self-harm and suicide. MATERIALS AND METHODS We reviewed the existing literature on the relationship between suicide and Internet use. RESULTS The accessibility of suicide-related information on the Internet seems to have an impact on the incidence of suicide behaviors. However, the Internet is useful for linking people who feel lonely or isolated, and it provides access to suicide prevention information and resources. The Internet can influence vulnerable people to attempt suicide, but it can also be used to prevent self-harm and suicide. CONCLUSIONS We propose some efforts that can be made in this preventive line.
