[Clinical evaluation of triage as drug-of-abuse test kit].
There are about 60,000 chemical substances which may cause poisoning. Identifying the cause substances is, therefore, very important for patient at emergency department. Triage is an immunoassay kit for the qualitative test for the metabolites of 8 major abuse drugs in urine. We assessed the usefullness of Triage on two patient groups. The first Group consists of the patients considered having not taken substances at initial diagnosis; the second Group consists of the patients considered having taken substances. The result are as follows. 1) The rate of Triage positive patients in the first Group were: attempt-suicide 23%, coma 24%, shock 10%, trauma 7%, respectively. Except for the habitually used medicine, narcotic and stimulant drugs were detected. In the first Group, negative result of Triage was effective in diagnosing the patients as not poisoned, excluding the possitivity of 8 major drugs usage. 2) The rate of Triage positive patients in the second Group were very high: attempt-suicide 77%, coma 51%, shock 57%, trauma 30%, respectively, showing mostly any of 8 major drugs were the cause of poisoning. In the second Group, positive result of Triage was effective in diagnosing the patient as poisoning or as coexisting poisoning with other diseases. 3) The specificity of Triage diagnosis in the first Group was 80% (113/142). The specificity and the sensitivity in the second Group were 64% (50/78) and 97% (74/76), respectively. These results means that Triage is very useful for diagnosis on 8 major drugs poisoning. 4) Triage is efficient for identifying the cause substances in drug poisoning and, therefore, can save medical expense. Triage is a very useful test kit at emergency department.
