Benzodiazepine use in a rural general practice population.

This study investigates the prevalence and pattern of benzodiazepine use in an isolated Australian rural general practice setting. Some clinical features of psychological dependence were also examined. Data were obtained from 771 patients attending each of two general practices over a five-day period. The results indicated that 11.3% of the sample had used a benzodiazepine in the preceding four weeks and that 82% of these had been regular users for over six months. Prevalence increased with age and 36.5% of patients over the age of 70 were using benzodiazepines. Features suggesting some degree of psychological dependence were found in over 50% of users. The findings illustrate the extensive and prolonged use of benzodiazepines and raise questions about overuse and dependence, particularly in the elderly.
