Advanced Practice Nurses' Roles and Responsibilities in Advance Care Planning for Older Persons—A Mixed Methods Systematic Review

To systematically identify, evaluate and synthesise the research literature about (a) the roles and responsibilities of advanced practice nurses (APNs) in the context of advance care planning (ACP) for older persons, (b) the characteristics of APNs' ACP practices and (c) the facilitators and barriers influencing APNs' involvement in ACP. Mixed-methods systematic review. Followed the mixed methods systematic review guidelines outlined by the Joanna Briggs Institute. Three researchers independently screened studies for eligibility using the Covidence Screening Application. The screening involved two stages: titles and abstracts, followed by full-text evaluation. The Mixed Methods Appraisal Tool was used for quality assessment. A convergent integrated synthesis combined quantitative and qualitative data by 'qualitising' quantitative findings into text, enabling integration and thematic analysis to synthesise the results. Medline, CINAHL and Embase were searched from 2012 to 2024 for original research in English, focusing on APNs involved in ACP for individuals aged 65 or older, using qualitative, quantitative or mixed method designs. The review included 19 studies: seven qualitative, nine quantitative and three mixed method designs. Thematic analysis revealed that APNs play a key role in ACP, aligning care with patient preferences through discussions and documentation. Studies from the United States (12), United Kingdom (4), Canada (2) and Australia (1) show varying APN roles and responsibilities. APNs are crucial to ACP, but barriers limit their impact. Overcoming these is key to improving outcomes. APNs clinical expertise and close patient relationships are crucial for aligning care with patient preferences and needs in ACP. However, to fully maximise their contribution, it is essential to overcome barriers such as time constraints, lack of role recognition and insufficient training. Addressing these challenges will enhance the effectiveness of APNs in providing person-centred care.
