The Influence Of Spirituality And Religiosity On Us Oncologists' Personal Use Of And Clinical Practices Regarding Complementary And Alternative Medicine

Background: Cancer patients frequently use complementary and alternative medicine (CAM), and spirituality has been associated with CAM use among patients. We evaluated how oncologists' spirituality and religiosity are associated with personal use and patient recommendations for CAM. Methods: A survey was mailed to 1000 medical oncologists in the United States. The questionnaire asked about oncologists' approaches to CAM use by patients, focusing on the use of herbs and supplement (HS), and about religiosity and spirituality. Results: Of 937 deliverable questionnaires, 392 were returned (response rate 42%). Respondents were mostly men (71%) and Caucasian (76%), with a median age of 48. Approximately 16% reported no religion, 19% Jewish, 24% Catholic, 28% Christian, and 13% other religions. Eighteen percent reported attending religious services at least once a week, including 15% who attend several times per week. Twenty-eight percent reported high theological pluralism (skepticism regarding whether one religion is comprehensively and uniquely true); 58% described themselves as moderately or very spiritual. Self-reported spirituality and religious service attendance were associated with using CAM personally and recommending HS to patients. In multivariate analyses, moderate-high spirituality and attending religious services less than monthly was positively associated with personal use of CAM: odds ratio (OR) = 3.10 (confidence interval [CI] = 1.5-6.5) and OR = 3.04 (CI = 1.5-6.6), respectively. Physicians with moderate to high spirituality were more likely to report recommending CAM in general (OR = 3.07, CI = 1.3-7.1), but less likely to report recommending HS (OR = 0.33, CI = 0.14-0.75). Conclusion: Self-reported spirituality is a significant factor among US oncologists' decision to use CAM and recommend CAM to patients.
