To describe benzodiazepine prescribing for elderly people living in the community in British Columbia, and to compare such prescribing with an indicator of current guidelines.
Descriptive analysis of pharmacy billing data.
Province of British Columbia.
All elderly persons (age 65 and older) dispensed benzodiazepines by community pharmacies in British Columbia during 1990.
Potentially inappropriate prescriptions were defined by a maximum 2-month limit of 20 diazepam equivalents daily, as determined by the BC Drug Usage Review Program in consultation with experts in the field. Physicians' rates of potentially inappropriate prescribing were determined per 100 benzodiazepine prescriptions written.
Almost 24% of elderly people in British Columbia were prescribed benzodiazepines at least once during 1990. Of these, 17.1% were given potentially inappropriate prescriptions. Physicians who prescribed benzodiazepines most frequently had the highest rates of potentially inappropriate prescriptions.
Prescribing practice does not correspond with our indicator of current guidelines.

药房计费数据的描述性分析。
不列颠哥伦比亚省。
1990年期间在不列颠哥伦比亚省社区药房领取苯二氮䓬类药物的所有老年人（65岁及以上）。
由不列颠哥伦比亚省药物使用审查计划与该领域专家协商确定，每日最大剂量为20地西泮等效剂量、最长使用期限为2个月的处方被定义为潜在不适当处方。根据开具的每100张苯二氮䓬类药物处方确定医生潜在不适当处方的比例。
1990年期间，不列颠哥伦比亚省近24%的老年人至少有一次开具苯二氮䓬类药物的处方。其中，17.1%的处方为潜在不适当处方。开具苯二氮䓬类药物最频繁的医生，其潜在不适当处方的比例最高。
处方行为与我们当前指南的指标不符。
