Name Percentage Rate of Beers Drug Use Among Seniors on Public Drug Programs
Description The rate of seniors who have a claim from the Beers list (an internationally recognized list of drugs that are identified as potentially inappropriate to prescribe to seniors due to an elevated risk of adverse effects)
Interpretation This indicator is interpreted as the rate of seniors who take a medication identified as potentially inappropriate to prescribe to seniors because they "are either ineffective or they pose unnecessarily high risk for older persons and a safer alternative is available." It should be noted that there may be cases where it is appropriate for seniors to take drugs on the Beers list.

Background, Interpretation and Benchmarks
Rationale

Seniors are at greater risk for adverse drug reactions (ADRs), as well as other types of drug-related adverse events, due to the number of drugs they take, the higher prevalence of certain chronic conditions and age-related changes in the body. The higher prevalence of chronic conditions does contribute to the number of drugs seniors take. However, it is important to evaluate the appropriateness of each medication prescribed. The Beers list is an internationally recognized list of drugs identified as potentially inappropriate to prescribe to seniors because they "are either ineffective or they pose unnecessarily high risk for older persons and a safer alternative is available."

Interpretation

This indicator is interpreted as the rate of seniors who take a medication identified as potentially inappropriate to prescribe to seniors because they "are either ineffective or they pose unnecessarily high risk for older persons and a safer alternative is available." It should be noted that there may be cases where it is appropriate for seniors to take drugs on the Beers list.

Quality Statement
Caveats and Limitations

The NPDUIS Database includes claims accepted by public drug programs, either for reimbursement or toward a deductible. Claims are included regardless of whether or not the patient actually used the drugs.

The NPDUIS Database does not include information regarding prescriptions that were written but never dispensed, prescriptions that were dispensed but for which the associated drug costs were not submitted to or not accepted by the public drug programs, or diagnoses or conditions for which prescriptions were written.

The NPDUIS Database contains claims data from public drug programs in Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia and Prince Edward Island. The First Nations and Inuit Health Branch (FNIHB), a federal drug program, also submits data, which comes from all Canadian provinces and territories (including those not listed above).
