Sweden has no systematic advance care planning (ACP), nor legal recognition of end-of-life proxies. We describe our experiences and reflections from a participatory action research process, aiming at developing and initially using a conversation-based, structured ACP approach among community-dwelling, older adults in Sweden. Eco-mapping and DöBra cards were used with 65 people to catalyze discussions on preferences for the end-of-life. We found great individual variation in both Eco-map depictions of social networks and prioritization of the 37 DöBra card items. The DöBra cards were concluded to be a viable tool for stimulating person-centered conversations on preferences for future end-of-life care.
