Area of Science:

  • Geriatric Medicine
  • Public Health
  • Pharmacoepidemiology

Background:

  • Polypharmacy is a growing concern among the elderly population.
  • Effective patient-provider communication is crucial for safe medication management in seniors.

Purpose of the Study:

  • To determine the prevalence of multiple-medication use in Canadian seniors.
  • To assess patient-physician and patient-pharmacist communication regarding medications in this demographic.

Main Methods:

  • Utilized Health Canada-sponsored supplementary questions from the 1994/95 National Population Health Survey (NPHS).
  • Employed weighted estimates to represent the Canadian population and age-standardized rates by sex.
  • Defined multiple-medication users as those reporting five or more drugs in the two days prior to the NPHS interview.

Main Results:

  • In 1994/95, 10% of Canadians aged 65-74 and 13% of those aged 75+ were identified as multiple-medication users.
  • A significant age-related decline was observed in the percentage of seniors reporting receiving drug information from their physicians.
  • Similarly, communication with pharmacists about medications also decreased with advancing age.

Conclusions:

  • Multiple-medication use was prevalent among Canadian seniors in 1994/95.
  • Age-related decreases in patient-physician and patient-pharmacist communication highlight potential gaps in medication information delivery to older adults.
