Publication Rates in Podium and Poster Presentations at the 2012-2014 American Association of Hip and Knee Surgeons Annual Meetings

Background

Subspecialty conferences are an important forum for disseminating the latest research relevant to clinical practice. The purpose of this study was to identify publication rates in podium and poster abstracts for the American Association of Hip and Knee Surgeons (AAHKS) Annual Meeting and to identify the most common journals of publication and the reasons for nonpublication.

Proceedings of the 48th Annual Pancreas Club Meeting

The 48th annual Pancreas Club meeting was held on May 2 and 3, 2014, at the Westin Lombard in Lombard, IL. Two hundred sixty attendees included pancreatologists from 17 countries. Two hundred eleven abstracts were submitted; from these, a record number (64) oral presentations and 136 posters were selected. Table 1 documents oral abstract titles with institutional affiliation. Full abstracts for all oral presentations and posters are available at the Pancreas Club website, http://pancreasclub.com. Representative abstracts from each of the eight sessions are summarized below.

Publication rate of abstracts presented at the British Association of Urological Surgeons Annual Meeting

OBJECTIVE: To determine the number of peer-reviewed publications arising from the abstracts presented at the annual meetings of the British Association of Urological Surgeons (BAUS), and to assess urological trainees' attitudes to research in relationship to the pursuit of Specialist Registrar (SpR) training numbers and their perception of academic urology in the UK. METHODS: Publications resulting from presentations at the annual meetings of the BAUS 2001 and 2002 were searched for using the PubMed database. Variables that might influence the subsequent publication of abstracts in peer-reviewed journals were analysed. Whether institutions from other countries had similar publication rates to those in the UK was also assessed. SpRs were interviewed about their motivation to convert presentations to publications before and after their appointment to SpR training. RESULTS: In July 2004, 142 of 449 abstracts presented at BAUS 2001 and 2002 were published, giving a publication rate of approximately 42% on Kaplan-Meier analysis. The rate of publication appeared to continue to the end of the period of searching for publications. The publication rate arising from UK presentations was lower than that from the non-UK presentations (hazard ratio 0.75, 95% confidence interval 0.49-1.15, P = 0.14). Publication rates from podium and poster presentations were similar. Urology journals accounted for 75% of the publications. Of the SpRs evaluated, 83% did research and presented papers to obtain a training number rather than because of an inherent interest to pursue an academic career. CONCLUSIONS: The conversion rate from BAUS presentation to peer-reviewed publication at 36 months was similar on Kaplan-Meier analysis to that of the American Urological Association (AUA, 38%). Interestingly, the rate of publication from the AUA seems to be faster than from BAUS. In addition, presentations from outside the UK appeared to be published faster than those from the UK. Delegates attending these conferences need to consider this when deciding whether a particular presentation will influence their practice. British urology requires academics who are interested in pursuing high-quality research, and which is presented at major conferences with an intention to publish it in peer-reviewed journals.     

Publication rate of abstracts presented at the Annual Congress of the Spine Society of Europe (years 2000–2003)

Introduction

The quality of presentations at medical conferences is of major importance. The publication rate (PR) following congress presentation is an indicator of the extent and quality of a scientific society’s activity. The purpose of this study was to investigate publication rates in the Spine Society of Europe (SSE), compare them with the results for American spine societies, and determine factors affecting publication.

Materials and methods

All 839 abstracts of podium and poster presentations at SSE congresses held in 2000–2003 were investigated. PRs in peer-reviewed journals within a period of 5 years were assessed. Subgroup analyses were performed for different study types. The consistency of abstracts with publications was also analyzed.

Results

The overall PR was 37.8%, with a mean of 17.7 ± 15.7 months between congress and publication and a mean impact factor of 1.8 ± 1.0 at the time of publication. Comparatively high PRs were found for podium presentations versus posters, studies with higher versus lower levels of evidence, experimental versus clinical studies, prospective versus retrospective studies, randomized versus nonrandomized studies, studies reporting significant main results versus those without, and multicenter studies versus single-center studies. Biomechanical studies also achieved high PRs.

Conclusion

The PR was similar to that of NASS (40%) and only slightly inferior to that of SRS (47%) and ISSLS (45%). This shows the high quality of presentations at SSE congresses. The fate of unpublished abstracts is worth further consideration. It is questionable whether it is acceptable to cite abstracts that have not passed a journal’s peer-review process and to implement their results in clinical practice.     

Summary of at the 45th Annual Pancreas Club Meeting Proceedings

Background  

The 45th meeting of the Pancreas Club was held on 5 and 6 May 2011 at the Robert H. Lurie Medical Research Center in Chicago, IL. An outstanding program of 47 oral presentations (Table 1) and 137 poster presentations was chosen from a record number of submitted abstracts. Ten posters each day were chosen for presentation as part of the Professor Rounds portion of the formal poster viewing program. Summaries of the oral presentations are provided; published work is referenced. Full abstracts are available on the Pancreas Club website: .     

Publication rate of General Surgery abstracts presented at the Royal Australasian College of Surgeons Annual Scientific Congress

Background

A commonly used metric for evaluating the quality and impact of presentations at a scientific meeting is the frequency with which the findings presented are published as full research papers in peer‐reviewed journals. The purpose of this study was to determine the full article publication rates of abstract presentations for General Surgery and related sub‐specialities at the Royal Australasian College of Surgeons Annual Scientific Congress (RACS ASC) from 2010 to 2014.

Methods

All General Surgical (including its sub‐speciality groups) abstracts presented at the RACS ASC from 2010 to 2014 were identified from the ANZ Journal of Surgery. We determined the rates of full paper publication, time to publication, journals of publication and specialty rates of conversion. Full article publications were identified using the PubMed, MEDLINE and Google Scholar databases.

Results

A total of 1386 abstracts were identified, of which 356 (26%) were converted to full paper publications. The number of abstracts presented annually increased from 206 in 2010 to 386 in 2014, but the percentage of abstracts converted to full paper publications did not follow any temporal trend. The majority (74%) of full papers were published within 2 years of the abstract presentation.

Conclusion

In total, 26% of General Surgery abstracts presented at the RACS ASC from 2010 to 2014 were converted to full paper publications. This could provide a baseline against which to judge the quality of presentations at other national General Surgical congresses, as well as at future RACS ASC meetings.     

Summary of the 42nd Annual Meeting of the Pancreas Club

The annual meeting of the Pancreas Club, traditionally held during the same week as the meetings of the Society for the Surgery of the Alimentary Tract and Digestive Disease Week was held at the University of California San Diego on May 18, 2008 and consisted of both oral presentations and selected poster sessions. Submissions for the program numbered 143 abstracts of which 29 were chosen for oral presentation. There were 19 10-min presentations and ten were 3 min in length. Each was followed by 5- and 2-min discussion periods, respectively. In addition, 50 of the submitted abstracts were chosen for a designated poster session. Summaries of the presentations comprise the body of this report. A summary of the work presented at the 42nd Pancreas Club Meeting, May 18, 2008, University of California San Diego.     

Publication of abstracts submitted to the annual meeting of the Pediatric Orthopaedic Society of North America

A computerized MEDLINE search was performed to determine the publication pattern of the abstracts submitted for podium presentation at the 1991-1994 annual meetings of the Pediatric Orthopaedic Society of North America (POSNA). The publication percentage for all papers submitted to the POSNA meetings from 1991 through 1994 was 45%. Fifty-three percent of papers accepted for podium presentation were ultimately published in comparison with 38% of those not accepted for presentation (p < 0.001). The mean time to publication was 29 months and did not differ significantly for the two groups. The majority of papers (65%) were published in either Journal of Pediatric Orthopaedics (48%) or The Journal of Bone and Joint Surgery (American) (17%). The frequency of ultimate publication of abstracts submitted to the annual POSNA meetings compares favorably with the rates for other medical subspecialties.     

Podium versus poster publication rates at the Orthopaedic Trauma Association

Original studies at orthopaedic meetings are presented on the podium and in poster format. Publication of those studies in peer-reviewed journals is the standard of communicating scientific data to colleagues. Investigators of previous studies have reported publication rates, but never differentiated between the modes of presentation. We evaluated the annual meeting of the Orthopaedic Trauma Association from 1994-1998 and found that studies presented on the podium were 1.3 times more likely to be published than those presented in a poster format (67% versus 52%). The mean time to publication was similar, 21.6 months for poster presentations and 24.8 months for podium presentations. Podium presentations were more likely to be published in the Journal of Orthopaedic Trauma, Clinical Orthopaedics and Related Research, and the Journal of Bone and Joint Surgery (American and British editions). Our findings suggest different rates and distribution of publication between podium and poster presentations at an international trauma meeting. These findings should be considered when evaluating studies of interest at the Orthopaedic Trauma Association meeting.     

Publication bias in papers presented to the Australian Orthopaedic Association Annual Scientific Meeting

BACKGROUND: The selective publication of articles based on factors, such as positive outcome, statistical significance and study size is known as publication bias. If publication bias is present, any clinical decision based on a review of the published work will also be biased. Publication bias has been shown in various specialties, based on review of publication rates for abstracts presented at major scientific meetings. This study was conducted to investigate publication bias in orthopaedics. METHODS: Abstracts presented at the 1998 Australian Orthopaedic Association Annual Scientific Meeting were reviewed independently by two reviewers. Details of sample size, study setting, country of origin, outcome and study type were recorded for each abstract. Publication within 5 years was ascertained by electronic searching of Medline and Embase databases and direct author contact. Logistic regression analysis was used to identify predictors of publication. RESULTS: The overall publication rate was 31%. Publication was more likely if the study was a laboratory study, rather than a clinical study (odds ratio (OR), 3.45; 95% confidence interval (CI) 1.69-7.01, P < 0.001). Sample size, country of origin, study type, statistical significance and positive outcome were not significantly associated with publication. CONCLUSION: According to this study, laboratory studies were significantly more likely to be published than clinical studies. In contrast to previous studies, publication bias due to the selective publication of papers with a positive outcome or those reporting statistical significance was not found.     

Introduction of cardiac surgery residency program at an earlier stage in surgical training

Objective

Reform of the Japanese postgraduate residency program has dramatically influenced the recruitment system. Because shortage of young cardiac surgeons is anticipated, an effective program for residents who want to become cardiac surgeons must be established at an earlier stage in surgical training.

Methods

A 3-year cardiac surgery residency curriculum was developed for senior residents. The surgical training program includes harvesting of the saphenous vein, radial artery and internal thoracic artery, and repair of abdominal aortic aneurysm and specifies the target number of surgical procedures for each training. Academic training is provided in addition to clinical skills training. Nine residents completed the 3-year program between 2004 and 2012. The number of surgical procedures performed, presentations made at scientific meetings, and scientific papers published were investigated and analyzed.

Results

Each resident participated in 438 operations during 3-year program, 25.9 ± 8.3 (5.9 %) as main operator and 182.2 ± 15.8 (42 %) as first assistant. The average number of procedures per resident over the 3 years was 43.0 ± 6.7 for saphenous vein harvest, 14.4 ± 3.9 for radial artery harvest, 27.9 ± 13.0 for internal thoracic artery harvest, 7.1 ± 4.6 for abdominal aortic aneurysm. In addition, over the 3 years, the mean number of presentations at scientific meetings was 13.2 ± 3.2 and the mean number of publication of scientific papers was 1.9 ± 1.4.

Conclusion

The new cardiac surgery training curriculum for residents worked fairly well. A system for assessment of the program by an authoritative body should be established in the future.     

Publication Rates of Presentations at an Annual Meeting of the American Academy of Orthopaedic Surgeons

Background  

The Program Committee of the American Academy of Orthopaedic Surgery (AAOS) continually tries to improve the quality of the scientific program at AAOS meetings. However, according to the most recent study, the publication rate of papers presented at the 1996 annual meeting was only 34%.     

The publication rates of presentations at major Spine Specialty Society meetings (NASS, SRS, ISSLS)

STUDY DESIGN: A review of all the presentations at three major spine specialty meetings held over a 3-year period. OBJECTIVES: To determine the rate of publication in peer-reviewed journals after presentations at major spine meetings conducted annually by the following three organizations: North American Spine Society (NASS), Scoliosis Research Society (SRS), and International Society for the Study of the Lumbar Spine (ISSLS). SUMMARY OF BACKGROUND DATA: The rate of publication for presentations at national and international meetings has been determined for medical and surgical subspecialties. This rate has been used to judge the quality of the content of the meetings and to determine the validity of the research presentations. METHODS: All presentations either in poster or oral presentation form were entered into a database covering a 3-year period for spine specialty meetings conducted annually by the following three organizations: NASS 1990 to 1992, SRS 1991 to 1993, and ISSLS 1991 to 1993. A computer search for each abstract was performed with the Melvyl Medline Plus database to determine if the abstract had been published in a peer-reviewed journal from 1990 to the end of 1997. Publication rates for presentations at these three meetings were determined over a 3-year period. RESULTS: A total of 1186 abstracts were listed over a 3-year period in the final programs of these three meetings for the years 1991 to 1993 (SRS, ISSLS) and 1990 to 1992 (NASS). Of these 1186 abstracts, 516 were published in peer-reviewed journals, giving an overall publication rate of 43.5%. The publication rates for the three different meetings (NASS, SRS, ISSLS) were similar, with values of 40%, 47%, and 45% respectively. More than 90% of the publications resulting from these meetings were published within a period of 4 years from the data of the meeting. CONCLUSIONS: The publication rates of presentations at three major spine specialty meetings are high and quite comparable with the publication rates of meetings in other medical subspecialties. This reflects the high quality of the meeting programs and validates their selection process.     

Fate of abstracts from the Paris 1995 European Society of Anaesthesiologists meeting

BACKGROUND AND OBJECTIVE: To assess the publication rate of full papers presented as abstracts at the 1995 meeting of the European Society of Anaesthesiologists, and to assess factors that might predict subsequent full publication. METHODS: All abstracts presented at the meeting and published in the British Journal of Anaesthesia (Suppl 1, 1995) were included. To verify subsequent full publication, a MEDLINE search was performed and validated. We studied the average time from the meeting to publication, the first author's country, the subspeciality, the publishing journal of the full report, the type of presentation (oral or poster), the object of investigation, and the quality of research design and of statistical reporting in the abstract. RESULTS: Of 472 meeting abstracts, 199 (42.2%) were eventually published. The average (+/- SD) delay between meeting and publication was 16.8 (15.6) months (range 24-60 months). Most papers (79.4%) had been published within 3 yr of the meeting. Circulation, pharmacology and intensive care papers had the highest rates of publication. Sixty-three journals attracted papers, with the British Journal of Anaesthesia publishing most (n = 29). No difference in subsequent publication was found between oral and poster presentations. Randomized trials and animal research were more likely to be published. The number of authors or their positions differed between the abstract and the full publication in 145 cases (72.9%); the first author was changed in 43 cases. CONCLUSIONS: Less than half of the abstracts accepted at the 1995 European Society of Anesthesiologists' meeting were subsequently published in journals indexed by MEDLINE in the 3 yr following the meeting. Many changes in authorship occurred between the abstract and the full publication. The study architecture and the object of investigation predicted full publication.     

Summary of Proceedings at the 43rd Annual Pancreas Club Meeting

The 43rd Meeting of the Pancreas Club was held on May 30 and 31, 2009 at Northwestern University coincident to the meetings of the Society for Surgery of the Alimentary Tract and Digestive Disease Week. For the first time, the Pancreas Club meeting was extended to 1.5 days. There were 115 abstract submissions of which 42 were chosen for oral presentation, and 67 were assigned to the poster category. Within the oral category, 30 were allowed 10 min for presentation and 5 min for discussion, while 12 were assigned to 3-min presentations followed by 2 min for discussion. In the poster group, 20 abstracts were selected for “Professor Rounds” discussion by senior pancreatologists during the formal poster viewing sessions.     

Publication rates of presentations made at annual meetings of the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America

The purpose of this study was to determine the publication rates of presentations made at the annual meetings of 2 sports medicine specialty societies--the American Orthopaedic Society for Sports Medicine (AOSSM) and the Arthroscopy Association of North America (AANA). We created a database covering annual AOSSM meetings from 1990 to 1993 (4 years) and annual AANA meetings from 1991 to 1993 (3 years) and searched the Melvyl Medline Plus database for abstracts from 1990 through 1998 to determine which had been published in peer-reviewed journals. Of the 333 abstracts listed for the 1990 to 1993 meetings, 198 (59.5%) were published in peer-reviewed journals. Publication rates of the AOSSM and AANA meetings were 68.1% and 50.9%, respectively. The majority of articles were published in American Journal of Sports Medicine (40.1%) and Arthroscopy (30.3%). Publication rates of presentations made at meetings of these sports medicine specialty societies are high and exceed the publication rates associated with meetings of other medicine specialty societies.     

Full text publication rates of papers presented at the British Foot and Ankle Society

Background

Techniques in foot and ankle surgery have expanded rapidly in recent years, often presented at national society meetings. It is important that research is published to guide evidence based practice. Many abstracts however do not go on to full text publication.
