Exploration of decision aids to support advance care planning: A scoping review

Abstract

BackgroundAdvance care planning is a process through which people communicate their goals and preferences for future medical care. Due to the complexity of the decision‐making process, decision aids can assist individuals in balancing potential benefits and risks of treatment options.ObjectiveWhile decision aids have the potential to better promote advance care planning, their characteristics, content and application effectiveness are unclear and lack systematic review. Therefore, we aimed to explore these three aspects and establish a foundation for future research.DesignScoping review.MethodsThis scoping review adheres to the framework proposed by Arksey and O'Malley and the PRISMA‐ScR list. Six English‐language databases were systematically searched from the time of construction until 1 December 2023. Two researchers conducted the article screening and data extraction, and the extracted data was presented in written tables and narrative summaries.ResultsOf the 1479 titles and abstracts, 20 studies fulfilled the inclusion criteria. Types of decision aids were employed, mainly websites and videos. Decision aid's primary components center around 11 areas, such as furnishing information, exploring treatment and care preferences. The main manifestations were a significant increase in knowledge and improved recognition of patients' target value preferences. Among the aids, websites and videos for advance care planning have relatively high content acceptability and decision‐making process satisfaction, but their feasibility has yet to be tested.ConclusionsDecision aids were varied, with content focused on describing key information and exploring treatment and care preferences. Regarding application effects, the aids successfully facilitated the advance care planning process and improved the quality of participants' decisions. Overall, decision aids are efficient in improving the decision‐making process for implementing advance care planning in cancer and geriatric populations. In the future, personalised decision aids should be developed based on continuous optimization of tools' quality and promoted for clinical application.Reporting MethodThe paper has adhered to the EQUATOR guidelines and referenced the PRISMAg‐ScR checklist.No Patient or Public ContributionThis is a review without patient and public contribution.Registration: https://doi.org/10.17605/OSF.IO/YPHKF, Open Science DOI: 10.17605/OSF.IO/YPHKF.
