Background: Digital approaches are being explored internationally to support the elicitation, documentation and sharing of advance care planning information. However, the views and experiences of patients and carers are little understood, impeding the development and impact of digital approaches to strengthen palliative and end-of-life care. Aim: To explore perspectives of patients with progressive illness and their carers on digital approaches to advance care planning, anticipated impact from their use and expectations for their future development. Design: A qualitative study employing thematic framework analysis of data collected from focus groups and semi-structured interviews. Setting/participants: Purposive sample of 29 patients and 15 current or bereaved carers in London and West Yorkshire from hospice settings, non-governmental support and advocacy groups, and care home residents. Results: Four generated themes included: 1. ‘ Why haven’t you read what’s wrong with me?’; uncertainty around professionals’ documenting, sharing and use of information; 2. The art of decision-making relies on the art of conversation; 3. The perceived value in having ‘ a say in matters’: control and responsibility; 4. Enabling patient and carer control of their records: ‘ custodianship is key’. Conclusions: Lived experiences of information sharing influenced trust and confidence in digital advance care planning systems. Despite scepticism about the extent that care can be delivered in line with their preferences, patients and carers acknowledge digital systems could facilitate care through contemporaneous and accurately documented wishes and preferences. There remains a need to determine how independent patient and public-facing advance care planning resources might be integrated with existing digital health record systems.
