To determine older adults’ awareness of the concept of medication‐induced harm and their familiarity with the term “deprescribing.” Secondary objectives were to ascertain determinants of self‐initiated deprescribing conversations and to identify how older adults seek information on medication harms.

Cross‐sectional population‐based household telephone survey using random‐digit dialling.

Canada.

Community‐dwelling adults aged 65 and older (N = 2,665; n = 898 men, n = 1,767 women, mean age 74.9 ± 7.2, range 65–100).

Information was gathered on age; sex; awareness of the term “deprescribing”; knowledge and information‐seeking behaviors related to medication harms; and previous initiation of a deprescribing conversation with a healthcare professional. Three targeted classes of potentially inappropriate prescriptions were asked about: sedative‐hypnotics, glyburide, and proton pump inhibitors. Descriptive statistics and regression analyses were used to quantify associations.

Two‐thirds (65.2%, 95% confidence interval (CI) = 63.4–67.0%) of participants were familiar with the concept of medication‐induced harms. Only 6.9% (95% CI = 5.9–7.8%) recognized the term deprescribing; 48% (95% CI = 46–50%) had researched medication‐related harms. Older adults most commonly sought information from the Internet (35.5%, 95% CI = 33.4–37.6%), and from health care professionals (32.2%, 95% CI = 30.1–34.3%). Patient‐initiated deprescribing conversations were associated with awareness of medication harms (odds ratio (OR) = 1.74, 95% CI = 1.46–2.07), familiarity with the term deprescribing (OR = 1.55, 95% CI = 1.13–2.12), and information‐seeking behaviors (OR = 4.57, 95% CI = 3.84–5.45), independent of age and sex.

Healthcare providers can facilitate patient‐initiated deprescribing conversations by providing information on medication harms and using the term “deprescribing.”
