Authorship, collaboration, and predictors of extramural funding in the emergency medicine literature

Of 5728 articles identified, there were 3278 (57%) original research, 1437 (25%) case reports/series, and 975 (17%) classified as others. The percentage funded was 22% for all articles (32% for original research). The literature had at least one EM investigator as coauthor 84% of the time. Article location of origin was the United States (63%), foreign (15%), and combined (22%). Multidisciplinary collaboration increased overall from 33% in 1994 to a high of 43% in 2003. Multi-institutional collaboration also increased from 16% in 1994 to 26% in 2003. The percentage of articles having 6 or more authors increased from 12% to 18% over the decade. Of all variables studied, only article type (original research: odds ratio, 4.8; 95% confidence interval, 4.0-5.6) and foreign source (non–United States: odds ratio, 1.3; 95% confidence interval, 1.1-1.5) predicted extramural funding.
