BACKGROUND: Complementary and alternative medicine (CAM) is now being increasingly used among cancer patients. The objectives of our study were to assess the prevalence, types, cost, subjective effects, and side effects of CAM use, reasons for CAM use, characteristics of CAM users compared to those of nonusers, and patients' expectations of doctors regarding their CAM use among Korean cancer patients at a single cancer center. METHODS: From April to August, 2003, we interviewed 186 cancer patients hospitalized in the Korea Cancer Center Hospital using a structured questionnaire, and analyzed the data. RESULTS: 78.5% of experimental subjects (146 patients) had been treated with at least one type of CAM, in addition to conventional Western treatment, with a mean monthly cost of 1, 380, 000 Won/person (approximately, 1, 100 U.S. dollars on July, 2004). The most prevalent types of CAM used by these patients included medicinal mushrooms (67.1%), herbs (54.1%), vegetable diets (50.6%), and ginseng (46.5%). The main reported reasons for the use of CAM in addition to conventional medicine were nutritional support (19.1%) and physical strengthening (17.8%). 5% of CAM users experienced side effects. The younger and more educated the patients were, the more likely they were to employ CAM. 66% of CAM users wanted to discuss CAM techniques with their doctors. CONCLUSION: More than two-thirds of cancer patients used various kinds of CAM, incurring considerable costs. Therefore, in order to help patients make informed decisions, medical society should be open to communication with patients. Not only the scientific aspects, but also the economic aspects of CAM usage should be examined more thoroughly, in order to ensure proper distribution of medical resources.

Drug utilization review (DUR) is one of the approaches to improve quality of health care and reduce its costs. DUR programs have been defined as "structured, ongoing initiatives that interpret patterns of drug use in relation to predetermined criteria, attempting to prevent or to minimize inappropriate prescribing while maximizing the effectiveness of drug therapy to save costs." There have been a limited number of papers to evaluate the economic consequences of DUR programs, and they provide no definite evidence regarding the cost saving or costeffectiveness of the programs. A possible explanation for this would be that DUR might not be awarded a high priority, resulting in reduced opportunities for financing to DUR including development of a good program and its evaluation study. However, despite these problems, in Korea simple descriptive studies of drug utilization and the development of effective intervention strategies must start and continue in order to optimize drug therapy and to save costs in health care. Pharmacoeconomic studies are employed to measure drug efficiencies, through comparison of the costs and effects of alternative therapies. Theses studies can uncover the economics repercussions of inappropriate prescribing and quantify the cost effectiveness of various DUR interventions. The use of DUR in conjunction with pharmacoeconomic analysis will result in more costeffective and rational utilization of medicines. Both methods could be used in a complementary fashion. In conclusion, DUR processes will lead to the better utilization of drugs, based on improved economic and social performance.
