Results: A total number of 222 elderly patients were included in this study. 45.5% (n = 101) of the participants agreed that they were taking a large number of medicines (95% CI = 38.89%–52.10%). 56.3% (n = 125) of the participants had the desire to reduce their number of medications (95% CI = 49.73%–62.88%). Majority of them (n = 185, 83.33%) agreed to involve themselves in deprescribing process if permitted by their health care provider. 86.9% (n = 193) of the participants tended to not be afraid of deprescribing of their regular medications after a series of investigations by their health care provider (95% CI = 81%–89%).
