title: Does routine screening for benzodiazepines help to diagnose dependence in psychiatric inpatients?
abstract: After admission, 899 inpatients of a psychiatric university hospital were routinely screened for benzodiazepines (BDZ) in the urine. BDZ were detected in 134 (15%) patients with various primary diagnoses. Criteria for BDZ abuse or dependence were found in 36 patients. In 35 cases, either intake of BDZ had not been reported in the first psychiatric interview, or such a report had not been documented in the patient's charts. None of these 35 patients was found to have BDZ abuse or dependence. Psychiatric inpatients with BDZ abuse or dependence seem to report their intake of BDZ. These findings suggest that a routine screening for BDZ can hardly help to diagnose dependence within a university hospital setting. Nevertheless, an objective test for intake of BDZ may be useful in special cases.
