Hypothesis

Are elderly patients with pre-existing risk factors for falls more likely to be prescribed benzodiazepines?

Conclusion

Elderly patients with conditions that increase the risk of falls are more likely to receive new benzodiazepine prescriptions.

Supporting Evidence

  • 69% of elderly patients never filled a benzodiazepine prescription.
  • 31% of patients filled at least one benzodiazepine prescription over five years.
  • Women were more likely to receive benzodiazepine prescriptions compared to men.

Takeaway

Older people who are already at risk of falling are often given medications that can make them fall even more.

Methodology

Logistic regression models were used to evaluate predictors of new benzodiazepine use among elderly patients in Quebec.

Potential Biases

Potential bias due to the inability to comprehensively capture mental health issues and the effects of multiple prescribing physicians.

Limitations

The study relied on administrative databases, which may not capture actual benzodiazepine use and could lead to under-reporting of certain conditions.

Participant Demographics

Average age was 73.4 years, with 52% being women.
