A Systematic Review of Clinical Interventions Facilitating End-of-Life Communication Between Patients and Family Caregivers.

Communication between patients and family caregivers plays a key role in successful end-of-life (EOL) care. In the majority of cases, health-care providers (HCP) are responsible for leading this communication in clinical settings. This systematic review aimed to examine the evidence for the efficacy of HCP-led interventions in enhancing communication between patients and family caregivers. The review followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and involved a search of MEDLINE via PubMed, CINAHL, Scopus, Embase, and PsycINFO as well as a manual search for additional articles on Google Scholar without date restrictions. Of 2955 articles retrieved, 8 meeting the eligibility criteria were included in the review. A quality appraisal of the selected studies was performed using the van Tulder Scale, with 5 of 8 studies rated as high quality. All 8 studies employed psychoeducational interventions involving both patients and surrogate/family caregivers. Common elements of the interventions reviewed included encouraging participant dyads to share their concerns about the patient's medical condition, clarify their goals and values for EOL care, and discuss their EOL care preferences. Of 8 interventions reviewed, 6 measured EOL care preference congruence within dyads as a primary outcome, and all 6 interventions were effective in increasing congruence. Secondary outcomes measured included decisional conflict and relationship quality, with mixed outcomes reported. This review suggests that HCP-led EOL communication interventions show promise for improving EOL care preference congruence. However, further studies with improved methodological rigor are needed to establish the optimal timing, intensity, and duration of interventions.
