What contributes to promote sexual health in cancer palliative care? A realist review.

Introduction: Sexuality is an important determinant of the overall health of a population and remains so at the end of life and in patients with advanced cancers. Despite the abundant literature on sexuality and intimacy, these topics have been rarely discussed in the context of cancer palliative care, and very few interventions to promote sexual health in patients undergoing cancer palliative care have been explored.

Objectives: In this study we sought to identify which factors and mechanisms contribute to promoting sexual health in cancer palliative care.

Methods: A realist review was performed according to the guidelines of the realist and meta-narrative evidence synthesis method guidelines. Articles published between January 2010 and June 2021 were searched in 4 databases. Records were screened for their relevance regarding a predefined list of context-mechanism-outcome (CMO) configurations. Abstracts were independently screened by 2 authors before the data were extracted from the full-text articles selected for inclusion. With the use of abductive and retroductive reasoning techniques, each article was examined for evidence of its contribution to one of the CMO configurations, which could be refined when relevant. The data were summarized according to the final CMO configurations.

Results: Of the 2056 articles identified, 38 articles were included in the review. The data reported in these articles contributed to 7 CMO hypotheses: (1) improving communication skills, (2) healthcare provider training, (3) reorganizing the patient environment in care settings or at home, (4) managing sexual symptoms and also general symptoms, (5 and 6) patient-centered counseling or couple counseling, and (7) lifting the taboo.

Conclusions: The findings reported here highlight various ways to improve sexual health for patients in cancer palliative care but are limited to genital cancers. Further research should consider all types of cancer rather than being restricted to genital cancers.
