Publication rate of radiodiagnostics specialists in Spain: bibliometric analysis based on publications in the journal Radiologia from 1984 to 1993

To analyze the yield of authors who have published articles in Radiologia between 1984 and 1993 according to known measurements of productivity, to identify those who are most productive, to analyze their productivity in Spanish and foreign journals and to calculate their approximate impact in Spain. The sources for our search were the IME and Medline databases, the journal Radiologia itself (vols. 26 to 35) and the Index of Citations of Medical Literature by Spanish Authors (Indice Medico Espanol nos. 107, 110, 113 and 116). A total of 2,580 authors participated in the 1.344 publications appearing the in journal: of these, 57% published a single article, while six authors (0.23%) were involved in the preparation of over 19 publications. The most productive authors also publish in other Spanish and foreign journals, and the impact of their works in Radiologia is similar to that of their overall impact in other journals. The productivity of authors of Spanish medical literature is similar to that of other medical journals, although there are too many authors whose index of productivity is low or moderate, a fact that is attributable to their collaboration in publications. Of those having a great volume of productivity, 61% also publish in other journals, and nearly 27% submit articles to foreign journals. With the tools available at present, it is not possible to evaluate the impact of the authors themselves, an aspect that requires specific studies. (Author) 26 refs
