Introducing palliative care in advanced cancer: a systematic review

Negative perceptions about palliative care (PC), held by patients with cancer and their families, are a barrier to early referral and the associated benefits. This review examines the approaches that support the task of introducing PC to patients and families and describes any evaluations of these approaches.

A systematic review with a systematic search informed by the Preferred Reporting Items for Systemic Reviews and Meta-Analyses guidelines was performed on the online databases MEDLINE, PsychInfo and CINAHL from May 2022 to July 2022. Identified studies were screened by title and abstract, and included if they were empirical studies and described an approach that supported the introduction of PC services for adult patients. A narrative-synthesis approach was used to extract and present the findings.

Searches yielded 1193 unique manuscripts, which, following title and abstract screening, were reduced to 31 papers subject to full-text review, with a final 12 studies meeting eligibility criteria. A diverse range of included studies described approaches used to introduce palliative care, which may be broadly summarised by four categories: education, clinical communication, building trust and rapport and integrative system approaches.

While educational approaches were helpful, they were less likely to change behaviours, with focused communication tasks also necessary to facilitate PC introduction. An established relationship and trust between patient and clinician were foundational to effective PC discussions. A framework to assist clinicians in this task is likely to be multidimensional in nature, although more quantitative research is necessary to establish the most effective methods and how they may be incorporated into clinical practice.
