[On the problem of industrial accidents under drug influence (author's transl)].

Industrial accidents resulting from technical defects have decreased in the last eights because of improved safety precautions. In contrast, accidents resulting from "human error" are increasing steadily. Toxicological urine analysis for drugs--directed mainly at soporifics, sedatives, tranquilizers, and pain-relievers--on 84 patients involved in industrial accidents yielded the following results. 1. Drugs were identified in 44 patients (= 52%). 2. In 13.4 patients, more than one drug was identified (= 16%). 3. Only five of the 44 patients admitted on being questioned that they had taken drugs (= 10%). On the other hand, in a control group of 47 persons who and not suffered any accident, drugs were detected in 19 cases (= 40%). The results show that the physician will have to take into account that healthy and efficient persons, too, are very often likely to practise drug abuse. It must be considered probable that this helps to promote accidents. Medical prescription, especially of neuroleptics and psychotropics, as well as of sedatives, should be practiced more.
