Polypharmacy is one risk factor for medication errors in older adults. This study describes the implementation of a pharmacist-administered deprescribing program in a long-term care facility in Canada. Over a one-year period, residents were randomized to receive either a deprescribing-focused medication review by a pharmacist or usual care. The intervention resulted in fewer medications taken by residents the intervention group after 6 months. Most deprescribing recommendations reflected a lack of ongoing indication or a dosage that was too high.
