Individuals who have purchased long-acting benzodiazepines (numerator), among Individuals aged 65 years or older (denominator)
Benzodiazepines are sleep-inducing and anti-anxiety drugs. Studies have shown that using benzodiazepines in the elderly increases the risk of accidents, falls and fractures. In addition, their use for extended periods of time may lead to problems associated with discontinuation and withdrawal symptoms . Hence, several guidelines and expert consensus statements recommend avoiding benzodiazepine use for longer periods, especially in older populations . Furthermore, Elderly persons are particularly sensitive to the side effects of benzodiazepines, due to the increased sensitivity of the nervous system, and a slower metabolism . Therefore, guidelines recommend that the use of long-acting benzodiazepines by older adults be avoided .
