The Influence of Patient and Provider Religious and Spiritual Beliefs on Treatment Decision Making in the Cancer Care Context.

Background: Providers often underestimate the influence of patient religious and spiritual (R&S) needs. The current study sought to determine the influence of R&S beliefs on treatment decision making among patients and providers in the context of cancer care.

Methods: We conducted a systematic review of the literature using web-based search engines and discipline-specific databases. Search terms included a combination of the following Medical Subject Headings and key terms: "cancer,""spirituality,""religion," and "decision making." We used Covidence to screen relevant studies and extracted data into Microsoft Excel.

Results: Among 311 screened studies, 32 met inclusion/exclusion criteria. Most studies evaluated the patient perspective ( = 29), while 2 studies evaluated the provider perspective and 1 study examined both. In assessing patient R&S relative to treatment decision making, we thematically characterized articles according to decision-making contexts, including general ( = 11), end-of-life/advance care planning ( = 13), and other: specific ( = 8). Specific contexts included, but were not limited to, clinical trial participation ( = 2) and use of complementary and alternative medicine ( = 4). Within end-of-life/advance care planning, there was a discrepancy regarding how R&S influenced treatment decision making. The influence of R&S on general treatment decision making was both active and passive, with some patients wanting more direct integration of their R&S beliefs in treatment decision making. In contrast, other patients were less aware of indirect R&S influences. Patient perception of the impact of R&S on treatment decision making varied relative to race/ethnicity, being more pronounced among Black patients.

Conclusion: Most articles focused on R&S relative to treatment decision making at the end of life, even though R&S appeared important across the care continuum. To improve patient-centered cancer care, providers need to be more aware of the impact of R&S on treatment decision making.
