目的：确定血液酒精浓度（BAC）为0.15或更高是否能准确识别被逮捕的酒驾司机的饮酒问题。设计：对86名酒驾者进行横断面分析研究（“诊断试验研究”）。地点：墨尔本圣文森特医院，酒驾教育项目。对象：年龄在18-25岁之间，在被取消驾驶资格后申请重新驾驶的男性，他们参加了1987年初连续10次的酒驾驾驶员教育课程。结果测量：自我报告的饮酒量和每周花在酒精上的钱，标准的密歇根酒精中毒筛查测试（MAST）得分和被捕时的血液酒精水平。前三项措施被用作酒精相关问题的参考标准，并与血液酒精水平进行比较。主要结果：酒精浓度与饮酒量、花费量和MAST分数的散点图显示，大量重度饮酒者没有被酒精浓度识别出来。经对数变换后的相关系数为：消费金额vs消费金额，r = 0.73；对于MAST分数与消费金额，r = 0.52；对于MAST分数与消费金额，r = 0.53。将BAC与MAST评分的对数相关联，r = 0.21， BAC与消耗量的对数相关联，r = 0.20， BAC与消耗量的对数相关联，r = 0.15。将BAC大于或等于0.15与大于或等于5的MAST评分进行比较，我们得到敏感性为0.36，特异性为0.76，阳性预测值为0.86，阴性预测值为0.23。通过MAST评分测量的重度饮酒患病率为0.80。结论：血液酒精浓度为0.15或更高的人只能识别出三分之一的酒驾者。虽然它选择了一组有酒精相关问题的饮酒者，但它错过了大多数有问题的饮酒者，也没有可靠地确定最严重的饮酒者。
Objective: To determine whether a blood alcohol concentration (BAC) of 0.15 or more identifies accurately problem drinking in an apprehended drinking driver.Design: Cross-sectional analytic study of 86 drink drivers ("diagnostic test study").Setting: St Vincent's Hospital, Melbourne, drink-driver education programme.Subjects: Men aged between 18-25 years, applying for relicensing after disqualification, who were participants at 10 consecutive drink-driver education courses conducted in early 1987.Outcome measures: Self-reports of the amount of alcohol consumed and the amount of money spent on alcohol per week, the standard Michigan Alcoholism Screening Test (MAST) score and the blood alcohol level at apprehension. The first three measures were used as reference standards for alcohol-related problems, against which the blood alcohol level was compared.Major results: Scatter plots of BAC against amount consumed, amount spent and the MAST scores showed that a large proportion of the heaviest drinkers were not identified by the BAC. Log-transformed correlation coefficients were: for amount spent v. amount consumed, r = 0.73; for MAST score v. amount consumed, r = 0.52, and for MAST score v. amount spent r = 0.53. Correlating the BAC with the log of the MAST score gave r = 0.21, BAC with log of the amount consumed, r = 0.20, and BAC with log of the amount spent, r = 0.15. Comparing a BAC of 0.15 or more with a MAST score of greater-than-or-equal-to 5, we obtained a sensitivity of 0.36, a specificity of 0.76, a positive predictive value of 0.86, and a negative predictive value of 0.23. The prevalence of heavy drinking as measured by the MAST score was 0.80.Conclusion: A blood alcohol concentration of 0.15 or more identifies only a third of the problem drinkers in this sample of drink drivers. Although it selected a group of drinkers with alcohol-related problems, it missed most of the problem drinkers and did not reliably identify the heaviest drinkers.
