The Role of Spirituality in Patients Undergoing Hematopoietic Stem Cell Transplantation: a Systematic Mixed Studies Review.

Background: Hematopoietic stem cell transplantation (HSCT) has become the standard treatment for many diseases, but it is an intense and distinctive experience for patients. HSCT-related mortality is present throughout the whole process of transplantation, from pretransplantation to recovery. Long-term rehabilitation and the uncertain risk of death evoke feelings of vulnerability, helplessness, and intense fear. Zimmermann et al. proposed that spiritual well-being is an important dimension of quality of life and that patients at the end stage of life require spiritual support in addition to physical care, psychological care, and social support. Therefore, the purpose of this review is to examine the role of spirituality in the process of HSCT.

Method: A systematic mixed studies review (SMSR) was based on Pluye and Hong's framework to understand the role of spirituality in patients' experiences while undergoing HSCT. We use the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement to report the results of integration.

Results: Fifteen original qualitative studies, 19 quantitative studies, and one mixed method study were included in the systematic mixed studies review. The evidence from the review revealed the following three themes: the spiritual experiences of HSCT patients, the spiritual coping styles of HSCT patients, and the spiritual need changes brought about by HSCT.

Discussion: Few medical institutions currently offer spiritual healing, although HSCT patients with different cultural backgrounds may have different spiritual experiences and spiritual coping styles. Psychotherapists or nurses should be considered to provide spiritual care for patients undergoing HSCT, to help patients cope with disease pressures, promote HSCT patients' comfort, and improve their quality of life.
