title: A survey of drug usage among patients admitted to a psychiatric hospital.
abstract: A six-month survey of the urinary concentrations of drugs and alcohol of 176 patients within one hour of their admission to the acute psychiatric wards of the Macquarie Hospital, Sydney, is reported. Non-prescribed drugs were detected in the urine specimens of 29.5% of patients and alcohol in the urine specimens of 13.6% of patients. The survey demonstrated inconsistencies between patients' reports of their recent drug or alcohol intake and the laboratory findings, and inadequacies in the information recorded and relayed to the laboratory at the time of patients' admission to the hospital.
