Objective. There is much evidence that driving under the influence of alcohol and/or drugs of abuse is related to an increased accident risk. A remaining question is whether the use of psychoactive substances is also related to clinically more severe accidents. The aim of this study is to explore the relationship between the use of psychoactive substances and the injury severity in a group of crash-involved drivers. Methods. The study group included all injured car drivers, admitted to the regional trauma center, in the period from May 2000 until August 2001. The outcome of interest was the severity of injury, measured by using the Injury Severity Score (ISS). The determinant was the presence of psychoactive substances in blood and urine samples. Psychoactive substances tested for were alcohol, amphetamines, barbiturates, benzodiazepines, cannabis, methadone, opiates, and tricyclic antidepressants in blood and urine. Results. The number of injured car drivers included in this study was 106. Overall, 43% (46/106) of the drivers tested positive for at least one psychoactive substance. Comparison of the means of the log ISS suggests that there is no significant difference between drivers who tested positive for alcohol and/or drugs, compared to drivers tested negative. Conclusion. The results of this study support the hypothesis that there is no clear association between use of psychoactive substances and the severity of crash-related injury. [ABSTRACT FROM AUTHOR]

To assess experiences related to antidepressant use reported to an internet-based medicine reporting system and to compare the nature of the side effects reported by patients with those reported by health care professionals (HCPs). All reports submitted from May 2004 to May 2005 to an internet-based medicine reporting system in The Netherlands related to the use of antidepressants were analysed. Spontaneous reports of adverse drug reactions on antidepressants from HCPs received by The Netherlands Pharmacovigilance Centre Lareb from May 2004 to May 2005 were included for comparison. Of the 2232 individuals who submitted a report to the internet-based medicine reporting system, 258 submitted a report on antidepressants. Of these, 92 individuals (36%) reported on effectiveness, 40 (16%) of whom reported on ineffectiveness, and 217 (84%) submitted a report on side effects, with 202 (78%) reporting a total of 630 side effects that were experienced as negative. Fourteen individuals (5%) reported a practical issue and four (2%) reported a reimbursement issue. Of all 630 side effects reported, 48% resulted in the patient discontinuing the antidepressant therapy; of these 29% did not inform their HCP. Of all the side effects reported, 52% were perceived as “very negative”. In comparison to the side effects reported by HCPs, patients more often reported apathy, excessive sweating, ineffectiveness, somnolence, insomnia, sexual problems and weight increase. Patients report the ineffectiveness and side effects of antidepressant therapy as negative and leading to discontinuation of the therapy. Patients and HCPs differ in the nature of the reported side effects. Patient experiences should be included in the evaluation of antidepressant treatment in clinical practice. [ABSTRACT FROM AUTHOR]
