What percent of abstracts presented at the American Academy of Orthopaedic Surgeons annual meeting are submitted, survive peer review, and eventually are published? The answer to this fundamental question is important because many national meeting attendees use the unscrutinized information that is presented to alter their surgical practices. At the 1993 American Academy of Orthopaedic Surgeons meeting, 573 abstracts were presented. After a 5-year period, 44% of abstracts presented were published as papers in a peer reviewed journal. The results suggest that for various reasons, the majority of presented material at the Academy meeting has not been authenticated scientifically to be as accurate as papers that survive the rigors of peer review.
