Percentage Rate of Beers Drug Use Among Seniors on Public Drug Programs

</td></tr>


<tr><td>Description</td><td>

The rate of seniors who have a claim from the Beers list (American Geriatrics Society \[AGS\] 2019 Updated Beers Criteria for Potentially Inappropriate Medication Use in Older Adults)

</td></tr>

<tr><td>Interpretation</td><td>

This indicator is interpreted as the rate of seniors who take a medication identified as potentially inappropriate to prescribe to seniors because it is either ineffective or it poses 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.

There may be differences in population characteristics (such as age and health status) between seniors with and without public coverage. In provinces where a lower proportion of seniors have claims accepted by the public plan, drug utilization patterns among those with public coverage are more likely to be affected by these differences and, therefore, may be less reflective of utilization patterns among all seniors in the province.

<tr><td>Rationale</td><td>

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 ineffective, they pose unnecessarily high risk for older persons or a safer alternative is available.

In the 2019 update, 2 medications (ticlopidine and pentazocine) were removed and 4 medications (glimepiride, homatropine, methscopolamine and pyrilamine) were added, compared with the 2015 criteria. These changes caused an absolute decrease of 0.3% in the proportion of seniors identified as using a drug meeting the Beers criteria.
