Coping with a patient's death is one of the most challenging events faced by healthcare professionals in clinical practice. A broad understanding of the coping strategies used by healthcare professionals is fundamental to the development of effective interventions and the provision of good bereavement care. This review aims to systematically synthesize the coping experience of healthcare professionals in the course of their work when they are confronted with patient deaths. PubMed, Embase, ScienceDirect, CINAHL, PsycINFO, Web of Science, Cochrane Library, Scopus, and Wiley online library were searched in April 2023 with no restriction on publication date. A 3-stage thematic synthesis method was applied for data integration and analysis. Thirty studies involving 545 participants met the inclusion criteria and scored a high level on quality assessment ranging from 9.0 to 10.0. Six themes were identified: emotional coping, cognitive coping, behavioral coping, relational coping, spiritual coping, and occupational coping. Overall, the coping strategies used by healthcare professionals in response to bereavement were found to be unique and multidimensional. Understanding how healthcare practitioners use emotional, cognitive, behavioral, relational, spiritual, and professional strategies to cope with bereavement will prove extremely beneficial in helping them to manage their grief, and can furthermore promote their professional growth and ensure the provision of excellent bereavement care for patients.
