Potentially inappropriate prescribing in long-term care and its relationship with probable delirium.

Potentially inappropriate prescribing (PIP) is common and can contribute to patient harm, including adverse drug events, functional decline, and death. This population-based study including over 171,000 long-term care residents in Ontario, Canada, examined the relationship between PIP and probable delirium. Researchers found that residents with three or more instances of PIP (measured by STOPP/START and Beers criteria) were significantly more likely to have probable delirium compared to residents with no instances of PIP.
