Introduction: Conference proceedings provide an opportunity for attendees to gain access to the most current information available. However, peer-review publication remains the standard for research. The purpose of this study was to determine the percentage of abstracts presented at ISASS that resulted in peer-reviewed publications, investigate factors possibly related to the progression from abstract to publication, and to compare the publication rate of ISASS abstracts to the rates reported for other spine/orthopaedic specialty societies.

Methods: Programs for the 2007 to 2010 ISASS conferences were reviewed and all abstract-based podium presentations were entered into a spreadsheet. Data recorded included title, authors, country/continent of origin (if authors were from multiple countries, the first author's affiliation was used), type of study (clinical, biomechanics, basic science), and study topic (artificial disc, tissue regeneration, interspinous device, etc). A total of 385 abstracts were recorded. Publication status was determined based on searching PubMed and the International Journal of Spine Surgery (formerly SAS J; the official ISASS journal). Searches were based on the abstract's first author and the study topic. Possible matches were further evaluated based on co-authors, and data including number of subjects, implant type, methods, results, and conclusions. Also analyzed was the length of time between the conference and publication dates. The publication rates were compared to those reported in the literature for other spine/orthopaedic conferences.

Results: Of 385 abstracts presented at ISASS, 31.3% were published as full-length manuscripts in peer-reviewed journals. The publication rate did not vary with continent of origin, study type, or study topic. The publication rate of 41.7% from the 2008 conference was significant greater than the other years (p< 0.05). Rates for the 2009 and 2010 conferences were the lowest, 23.3% and 28.6% respectively. The number of years between presentation and publication ranged from 0 (published same year as conference) to 5 years. Table 1 provides the percentages of papers published each year after the meeting. The publication rates reported for presentations at other spine/orthopaedic conferences are presented in Table 2.

Among spine meetings, ISSLS and SRS had the highest publication rates. Of note, the rate varied as much as 17% for a conference as well-established as AAOS.

Conclusions: The rate of ISASS presentations resulting in peer-reviewed journal publications was comparable to other spine/orthopaedic conferences, although lower than SRS and ISSLS. Considering the number of papers published up to 5 years after presentation at a conference, which occurred for all of the societies reviewed, the overall ISASS publication rate may rise slightly, particularly for the 2009 and 2010 meetings.
