[Spanish scientific production in antimicrobial agents and susceptibility procedures during period 1990-2002].

The aim of this study was to analyze the scientific production of Spanish authors on antimicrobial agents and susceptibility tests during the period 1990-2002. Articles from Spanish scientific institutions of microbiology, bacteriology, mycology and parasitology published and recorded in the MEDLINE database (WEBSPIRS version 4.2) during the period 1990-2002 were selected. Only articles about antimicrobial agents and susceptibility procedures were reviewed. A total of 5,259 documents were analyzed, of which 1,041 (19.8%) were about antimicrobal agents. The annual number of documents increased by two-fold (from 48 in 1990 to 101 in 2002). The journal that published most documents was Antimicrobial Agents and Chemotherapy, with 183 (17.1%). The main field of interest of the documents was antimicrobial agents and susceptibility tests (765; 73.5%) and in vitro resistance analyses (265; 25.5%). The highest number of contributions came from hospitals (571; 54.9%), followed by universities (351; 33.7%). The institutions with most documents published were the Ramón y Cajal Hospital (8.6%), and Seville University Faculty of Medicine (6%). The most productive autonomous communities were Madrid (43.4%), Catalonia (16.4%) and Andalusia (4.7%). A total of 787 documents (75.6%) were published in journals with impact factors and the mean expected impact factor was 2.390 +/- 1.546. It was concluded that the scientific production of Spanish researchers in antimicrobial agents had increased during the period 1990-2002, and that hospitals were the most productive institutions in this area of microbiology, with the main areas of interest being antimicrobial agents and susceptibility tests.
