摘要
目的:对常用的7种吞咽困难的筛选方法进行敏感度、特异度等研究,期望找出比较满意的筛选试验供临床选择使用。方法:对连续住院的56例患者进行7种筛选试验检查及电视透视检查。以后者为金标准计算敏感度、特异度、阳性预测值、阴性预测值、验后概率。结果:敏感度最高的是筛选试验3,4,6(95.8%),特异度最好的是7(70.7%),筛选试验2的阳性预测值最好(70.0%),试验3、4的阴性预测值最高(90.0%)。筛选试验3和4各项指标完全一致,因此实际使用中二者可以相互替代。验后概率最好的是筛选试验1(63.2%)。结论:临床上筛选试验3,4可以首先选用,试验1,2也不失为较好的筛选试验。
AIM:To study the sensitivity,specificity,predictive value and posttest probability of common seven ways for screening dysphagia. METHODS:Fifty six consecutive inpatients with dysphagia after stroke were enrolled in the study.They completed the seven screening tests and videofluorography.The latter included the sensitivity,specificity,predictive value and posttest probability. RESULTS:The highest sensitivity(95.8%) was found in test 3,4 and 6,the best specificity(70.7%)in test 7,the highest positive predictive value(70.0%) in test 2,the highest negative predictive value(90.0%) in test 3 and 4,and the best posttest probability(63.2%) in test 1.The indexes in test 3 were completely coincident with those in test 4 so that the indexes in the two tests could be interchanged. CONCLUSION:Test 3 and 4 is preferred in clinic and test 1 and 2 is secondary.
