Prevalence of complementary and alternative medicine use in brain tumor patients at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.

Objectives: To determine the prevalence and types of complementary and alternative medicine (CAM) being utilized and the possible factors that prompted the use of CAM in patients with brain tumors. Methods: The study conducted was a questionnaire-based, cross-sectional study of patients diagnosed with brain tumors at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia from January 2011 to May 2018. Patients with primary and secondary brain tumors, were included. Our questionnaire was conducted via phone interviews after obtaining patient consent. Results: A total of 72 patients were included. The mean age of the participants was 45.89 (+/- 16.52) years. We found that education level significantly affected the use of CAM. Fewer users of CAM held bachelor's degree and patients with lower degrees used CAM more frequently (p=0.027). The most frequent types of CAM were Zamzam (holy water) and Ruqya (Quran reading). Family members were the most frequent source of information about the use of CAM (81.6%). Conclusion: Education level has a significant effect on CAM use. Gender plays a role in the type of CAM used. Future research should focus on the adverse effects of some CAM therapies, how effective CAM therapies are, and the effect CAM may play in delaying patients from seeking medical advice.
