Impact of Spiritual Support Interventions on the Quality of Life of Patients Who Receive Palliative Care: A Systematic Review.

Background: Palliative care focuses on the prevention of worsening health, improving the quality of the patient's life, and the relief of suffering, and therefore has a considerable impact on both the patient suffering from a life-threatening or potentially life-threatening illness and on their family. Spirituality, as the dimension of human life involving the search for meaning, purpose, and transcendence, and connection with oneself, others, and the sacred, could be essential in supporting these patients. The aim of this study was to synthesise the scientific evidence describing the interventions and/or activities undertaken to meet the spiritual needs of the palliative patient.

Methods: A literature search was carried out across the following databases: PubMed, LILACS, Scopus, and Web of Science. The PRISMA statement was used to guide this review.

Results: Twenty-four articles were included. The thematic categories included spiritual needs at the end of life, the influence of music and dance as palliative care, care for family caregivers, and the comparison between counselling and dignity therapy.

Conclusions: Interventions in the biopsychosocial-spiritual spheres impact on the patient's peace of mind and promote the acceptance of a "good death". Healthcare personnel play an essential role in the way their patients prepare for the moment of death, and the meaning and values they convey help them to accompany and welcome patients. Last but not least, universities can play a crucial role by training nurses to integrate spiritual interventions such as music and dance, or by considering the family as a unit of care. The systematic review protocol was registered in the Prospective International Register of Systematic Reviews (PROSPERO) under protocol number CRD42023490852.
