Italian researchers investigated the knowledge of Italian oncology nurses in relation to CAM. A survey was carried out in 2007 with 270 nurses registered with the Italian Association of Oncology Nursing. A self-administered questionnaire was used and the response rate was 57.4% (155/270). Ninety-four (60.6%) nurses claimed to have knowledge about CAM. Over two-thirds (60.6%, 57/94) reported that books were a primary source of their knowledge. Other common sources included other healthcare workers (50%, 47/94), the Internet (48.9%, 46/94), workshops and seminars (29.8%, 28/94), and formal nursing education (17.0%, 16/94). Only 5.3% (5/94) reported that professional journals were a source of knowledge. During their professional activities, 71.6% (111/155) of the nurses encountered patients using CAM, while 47.1% (73/155) treated patients asking for information about these techniques.
