Presentations at 29 conferences of the Spanish Society of Emergency Medicine (SEMES) from 1988 to 2017: a descriptive analysis.

OBJECTIVES: To gain greater understanding of the development of emergency medicine in Spain by analyzing the presentations at conferences of the Spanish Society of Emergency Medicine (SEMES) over the past 30 years (1988-2017).

MATERIAL AND METHODS: We examined the programs of all SEMES conferences and described the characteristics of both presentations and presenters. We also analyzed changes occurring between 1988 and 2017 of some of the characteristics observed. The Web of Science was searched to evaluate the scientific productivity of the most frequent presenters and to calculate h-indexes for those presenters to assesstheir scientific relevance.

RESULTS: . SEMES did not hold a conference in 1992. The total of 29 conferences included 2182 presentations (112 listing presenters from abroad) given by 1410 presenters (89 from abroad). The presenters' affiliations named 616 centers. The number of presentations and presenters increased linearly during the first period and then leveled off. The number increased exponentially in the final phase. Men gave 79.6% of the presentations; 70.6% of the presenters were physicians, 11.9% were nurses and 4.0% were ambulance staff. Specialists in emergency medicine accounted for 60.8% of the presenters who were physicians. Presenters from the Spanish autonomous community organizing the conference gave 29.8% of the presentations. The contributions of presenters from the local organizing community were nearly always more numerous than the average number of contributions from that community in all 29 conferences overall. Conference contributions from some autonomous communities (Extremadura, Andalusia, and Catalonia) were considerably fewer than would be expected given the scientific productivity of those communities. However, communities (Murcia, Balearic Islands, Asturias, Castile-Leon, Madrid), gave many more presentations than their productivity metrics would predict. Analysis of the 59 most frequent presenters (at 5 conferences or more) showed that 64.4% of them had published at least 20 articles and that 71.2% had an h-index of 5 or higher. The number of women on the program increased significantly between 1988 and 2017. Likewise, geographic diversity increased significantly (presentations from centers outside the local organizing area) as did the participation of hospitalbased emergency medicine specialists.

CONCLUSION: SEMES conference programs have attracted significantly more presentations and presenters over the years. We also detected changes in descriptive characteristics. The analysis of those characteristics can help future SEMES conference planners to plan ways to correct aspects such as scarce geographic diversity, low international participation, and few women among presenters.
