Can a simple online tool help people with memory loss plan their future medical care?

This study tested whether sending a simple online planning tool through a patient portal could help older adults with mild memory problems have better conversations with their doctors about their future medical care wishes. Researchers wanted to see if using this tool made it more likely for these important preferences to be discussed and officially recorded in the patient's medical chart. The goal was to understand if this approach is practical and helpful for patients and doctors.
