Speakers provide one of the most promising methods of influencing prescribers. They are typically clinicians who have experience with a product and, coupled with their scientific training, have the know-how to determine how to guide their colleagues who may have less experience with the product. Peer-to-peer works. This is why companies spend hundreds of millions of dollars annually on speaker programs. Truly developing speakers with impact, while minimizing costs, is the holy grail of medical education.
