Complementary and Alternative Medicine Use among Cancer Patients at the End of Life: Korean National Study

Abstract

<br/><b>Objectives</b>: To investigate in depth the use of complementary and alternative medicines (CAMs) bycancer patients at the end-of-life (EOL) and how they communicate with physicians about them. Designand location: In 17 hospitals in Korea between January and December 2004 we identified 4,042 familiesof cancer patients. <br/><b>Results</b>: The prevalence of CAM use among cancer patients at the EOL was 37.0%,and 93.1% had used pharmacologic types of agents. The most frequent motive for CAM use was therecommendation of friends or a close relative (53.4%) or a physician (1.6%). Only 42.5% discussed CAMuse with their physicians. Satisfaction with CAMS was recalled for 37.1% . The most common reason givenfor that satisfaction was improvement of emotional or physical well-being, while ineffectiveness was themost common reason given for dissatisfaction. The average cost of CAM during the last month of life was$US 900. CAM use was associated with longer disease periods, primary cancers other than liver, biliary,and pancreatic, and need of support from physicians or religion. <br/><b>Conclusions</b>: CAM use among cancerpatients at the EOL was common, not discussed with physicians, and associated with expectation of cure.Expectations were generally unmet while the treatments were a financial burden. Further studies evaluatingthe effects of CAM at the EOL and factors that enhance communication with the physician are needed.
