How can existential or spiritual strengths be fostered in palliative care? An interpretative synthesis of recent literature.

BACKGROUND: Patients receiving palliative care may benefit greatly when their existential or spiritual strengths are fostered. To date however, there has not been a comprehensive literature review of patient and care professional approaches that are available.

AIMS: To describe and synthesise existential or spiritual strength-based approaches within the context of palliative care.

METHODS: Literature search of 2436 articles between January 1999 and March 2019 in Scopus, Web of Science, CINAHL and PsycINFO. Articles were included if they deal with a palliative care situation, focus on the patient, specific existential/spiritual strength, discernible strength approach and an analysis of the workings of that approach. The interpretative synthesis consisted of a thematic analysis of the included articles and an integration of themes.

RESULTS: In the 14 included articles, 5 different strengths were found to be fostered by 16 approaches: (1) Meaning was fostered by: maintaining normalcy, experiencing sanctuaries, reassessing importance and reconstructing positive self; (2) Connection by: opening up, giving/receiving care and envisioning continuation; (3) Agency by: maintaining control, refocusing goals and continuous adaptation; (4) Hope through: setting special targets, imagining alternate outcomes, building a collection and extending wishes; (5) Faith through: living the tradition and relating to a benevolent force. Strengths and approaches are visualised in an overarching analytical framework: 'the Propeller'.

CONCLUSIONS: The constructed Propeller framework can be used to become aware of, apply and further develop approaches to foster existential or spiritual strengths among patients receiving palliative care.
