Aims To examine the prevalence of drug driving, the prevalence of drug‐related motor vehicle accidents, risk perceptions of drug driving and factors associated with drug driving among injecting drug users (IDU). Design Cross‐sectional survey. Setting Sydney, Australia. Participants Three hundred current IDU. Findings Ninety‐five per cent had driven a vehicle, 74% in the previous 12 months (‘current drivers’). Eighty‐seven per cent of life‐time drivers reported having drug driven, and 88% of current drivers had drug driven in the previous 12 months. There were no significant sex differences in life‐time or recent drug driving. The most common drugs used before driving in the preceding year were: cannabis, heroin, amphetamines and cocaine. A third of life‐time drivers reported having had a drug driving accident, with males more likely to have done so, and 9% of current drivers reported a drug driving accident in the previous year. The most common drugs that had been used before the most recent drug driving accident were heroin, cannabis and alcohol. Alcohol was perceived to be the most dangerous substance for driving performance and cannabis the least dangerous. Recent drug drivers perceived drug driving to be less dangerous than non‐drug drivers. Recent drug drivers had driven more frequently over the preceding 12 months, had significantly higher levels of dependence, higher frequency of drug use, more extensive polydrug use and were more likely to have used and/or injected a drug in a car in the previous 12 months. Conclusions Drug driving and drug‐related accidents are large‐scale public health problems among IDU. These behaviours pose serious risks to IDU themselves and to the broader community. 相似文献

Lisa Ottomanelli Scott D. Barnett Lance L. Goetz Richard Toscano 《Topics in spinal cord injury rehabilitation》2015,21(1):31-39
Background:
Designing effective vocational programs for persons with spinal cord injury (SCI) is essential for improving return to work outcome following injury. The relationship between specific vocational services and positive employment outcome has not been empirically studied.Objective:
To examine the association of specific vocational service activities as predictors of employment.Method:
Secondary analysis of a randomized, controlled trial of evidence-based supported employment (EBSE) with 12-month follow-up data among 81 Veteran participants with SCI.Results:
Primary activities recorded were vocational counseling (23.9%) and vocational case management (23.8%). As expected, job development and employment supports were the most time-consuming activities per appointment. Though the amount of time spent in weekly appointments did not differ by employment outcome, participants obtaining competitive employment averaged significantly more individual activities per appointment. Further, for these participants, job development or placement and employment follow-along or supports were more likely to occur and vocational counseling was less likely to occur. Community-based employment services, including job development or placement and employment follow-along or supports as part of a supported employment model, were associated with competitive employment outcomes. Office-based vocational counseling services, which are common to general models of vocational rehabilitation, were associated with a lack of employment.Conclusions:
Vocational services that actively engage Veterans with SCI in job seeking and acquisition and that provide on-the-job support are more likely to lead to employment than general vocational counseling that involves only job preparation. 相似文献48.

目的了解高职护理专业学生对老年高血压患者家庭护理的认知与态度。方法对218例高职学生进行关于老年高血压患者家庭护理的问卷调查,内容包括疾病基本知识、营养知识、健康教育、心理护理、家庭护理技能以及异常情况观察等方面。结果高职学生对老年高血压及其家庭护理了解程度较好者占19.72%和32.57%;有一定了解者占52.29%和45.41%;完全不了解者27.98%和22.02%。其相关知识问卷总分为(51.66±4.02)分;其中对心理护理了解最差,其次为营养知识、健康教育、疾病基本知识、异常情况的观察、家庭护理技能。结论高职学生对老年高血压患者家庭护理的认知与态度不容乐观,应加强相关知识和技能的教育,对减少患者并发症的发生、提高其生活质量具有重要意义。 相似文献
