Benzodiazepine use among older adults is common despite evidence for many potential risks. While treatment guidelines recommend short-term use of benzodiazepines, up to one-third of use is long term, which is most common among older adults. To reduce benzodiazepine prescribing to older adults, one potential point for intervention is at the transition from new to long-term use, yet little is known about the factors that predict conversion to long-term use.
