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 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. |

Calculation: Description | The total number of seniors with at least one claim for a drug from the Beers list that was accepted by a public drug program divided by the total number of seniors with at least one claim for any drug accepted by a public drug program Unit of Analysis: Patients |

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 a commonly used 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. |

Caveats and Limitations |
The National Prescription Drug Utilization Information System (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 – Diagnoses or conditions for which prescriptions were written The NPDUIS Database contains claims data from public drug programs in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador. 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). |
