Continuing medical education (CME) is continuing education (CE) that helps those in the medical field maintain competence and learn about new and developing areas of their field. These activities may take place as live events, written publications, online programs, audio, video, or other electronic media. Content for these programs is developed, reviewed, and delivered by faculty who are experts in their individual clinical areas. Similar to the process used in academic journals, any potentially conflicting financial relationships for faculty members must be both disclosed and resolved in a meaningful way. However, critics complain that drug and device manufacturers often use their financial sponsorship to bias CMEs towards marketing their own products. Continuing medical education is not a new concept. From essentially the beginning of institutionalized medical instruction (medical instruction affiliated with medical colleges and teaching hospitals), health practitioners continued their learning by meeting with their peers. Grand rounds, case discussions, and meetings to discuss published medical papers constituted the continuing learning experience. In the 1950s through to the 1980s, CME was increasingly funded by the pharmaceutical industry. Concerns regarding informational bias (both intentional and unintentional) led to increasing scrutiny of the CME funding sources. This led to the establishment of certifying agencies such as the Society for Academic Continuing Medical Education which is an umbrella organization representing medical associations and bodies of academic medicine from the United States, Canada, Great Britain and Europe. The pharmaceutical industry has also developed guidelines regarding drug detailing and industry sponsorship of CME, such as the Pharmaceutical Advertising Advisory Board (PAAB) and Canada's Research-Based Pharmaceutical Companies (Rx&D). In the United States, many states require CME for medical professionals to maintain their licenses.
