This study provides early evidence that a multi-component communication intervention to engage both older adults and involved family in ACP in the primary care context is acceptable. More than half of participating patients adopted one or more therapeutic components of SHARING Choices: nearly half engaged in at least one ACP conversation and two-thirds provided the primary care clinic with a new or previously completed advance directive for documentation in their electronic health record. Although patient and family ACP engagement changed little over the 6-week observation period, open-ended comments at six weeks indicate that patients and family who engaged in the program found value in intervention components.
