[Incidence of anonymous medication before admission to the hospital (author's transl)].

Only about 1/4 of the statements made by the patients or accompanying persons regarding preclinical medication proved to be true. In about 66% of the cases 1--5 drugs were not stated during the first interview, while in 10% of the cases more drugs were stated than had actually been taken. Among the substances which had remained anonymous, the main shares are represented by benzodiazepines (28%), narcotic drugs (19%), neuroleptics (15%) and alcohol (15%). If one relates the number of false statements to the individual patients grouped according to diagnoses, the relatively highest quota of defaulters is found among the addicts, namely, 100%. This means that all the addicts had made false statements. The second rank is occupied by the alcoholic group who made 66% false statements, followed by the patients suffering from psychoses with 52% false statement, and the depressive patients with 47% false statements.
