BACKGROUND: Advance care planning is well established in general medical wards, but its implementation in anaesthesia and perioperative care presents unique challenges. Effective communication and shared decision-making regarding treatment limitations are essential to clarify care goals and provide timely, high-quality end-of-life care. Terminally ill patients with complex care needs can experience a higher risk of postoperative mortality during anaesthesia. METHODS: This scoping review examines the literature describing when and how advance care planning has been studied in perioperative care, focusing on patient characteristics, the content of advance care planning discussions, and impact on patient outcomes. The study follows PRISMA-ScR guidelines. Articles were collected from MEDLINE, CENTRAL, and CINAHL databases, using search terms from MeSH and synonyms for anaesthesia, surgery and perioperative care, advance care planning, living wills or advance directives, goals of care and terminal care, resuscitation orders, shared decision-making, and palliative care discussions. RESULTS: Advance care planning documentation varies across surgical specialties and settings, with higher rates in emergency and palliative surgery. Patient factors, such as age and comorbidities, impact completion of advance care planning. Structurally, the presence of interdisciplinary teams, increased decision-making aids, and structured discussions improve implementation. Barriers included a lack of consistency in terminology, poor timing of needed conversations, a lack of cultural sensitivities, and patient fears of abandonment and palliative care. CONCLUSIONS: Further research is required to determine the most appropriate and beneficial methods and outcomes for implementing advance care planning into perioperative and end-of-life care, ensuring appropriate, timely, and patient-oriented care delivery.
