Use of Complementary and Alternative Medicine Among Patients: Classification Criteria Determine Level of Use
Background and objectives: Self-reported use of complementary and alternative medicine (CAM) among patients varies widely between studies, possibly because the definition of a CAM user is not comparable. This makes it difficult to compare studies. The aim of this study is to present a six-level model for classifying patients' reported exposure to CAM. Prayer, physical exercise, special diets, over-the-counter products/CAM techniques, and personal visits to a CAM practitioner are successively removed from the model in a reductive fashion. Methods: By applying the model to responses given by Norwegian patients with cancer, we found that 72% use CAM if the user was defined to include all types of CAM. This proportion was reduced successively to only 11% in the same patient group when a CAM user was defined as a user visiting a CAM practitioner four or more times. When considering a sample of 10 recently published studies of CAM use among patients with breast cancer, we found 98% use when the CAM user was defined to include all sorts of CAM. This proportion was reduced successively to only 20% when a CAM user was defined as a user of a CAM practitioner. Conclusions: We recommend future surveys of CAM use to report at more than one level and to clarify which intensity level of CAM use the report is based on.
