As people age, they can end up taking many medications. Certain medications might have made sense when they were started. But as people get older, some medications may no longer be needed, or may be unsafe. It makes sense to consider stopping such medications. It can be tough for prescribers and patients to decide when and how to stop a medication. From 2014 to 2017, we developed guidelines and resources to help patients and prescribers make decisions about stopping medications. Our guidelines and resources are used in Canada and across the world. However, guidelines and resources need to be up to date with the most current evidence. There also needs to be ongoing strategies to ensure guidelines are used in the real world. This project, led from UBC Vancouver, will first survey patients and prescribers to assess needs and priorities for guidelines on stopping medications. We will then update our guidelines based on needs and current evidence. Finally, we will design knowledge translation materials together with patients and prescribers (called “co-design”), and spread the word about our updated resources. We strive to help patients/prescribers decide when and how to stop medications and improve well-being of older adults.
