In hospitalized older adults, a CAS-based pharmacist-physician intervention, compared to usual clinical care, resulted in significant higher number of drug cessation and dosage reductions for targeted PIMs.

The intervention model reduced high-risk medication use in older inpatients. Most of the vulnerable inpatients identified by CAS alerts would not have otherwise had a geriatric medication review.

A KT strategy resulted in decreased use of PIM in elderly adults in the hospital. Additional interventions will be implemented to maintain or further reduce PIM use.
