bConselleria de Sanitat, Generalitat Valenciana, Valencia, Spain. OBJECTIVE: Citation analysis elucidates patterns of information consumption within professional communities. The aim of this study was to analyze the citations of 87 Spanish medical journals by calculating their impact factors and immediacy indices for 2001, and to estimate the importance of ARCHIVOS DE BRONCONEUMOLOGIA within the framework of Spanish medicine. MATERIAL AND METHOD: Eighty-seven Spanish medical journals were included. All were listed in the Spanish Medical Index (Indice Medico Espanol) and in at least one of the following databases: MEDLINE, BIOSIS, EMBASE, or Science Citation Index. References to articles from 1999 through 2001 in citable articles from 2001 were analyzed. Using the method of the Institute for Scientific Information, we calculated the national impact factor and immediacy index for each journal. RESULTS: The journals with the highest national impact factors were Revista Espanola de Quimioterapia (0.894), Medicina Clinica (0.89), and ARCHIVOS DE BRONCONEUMOLOGIA (0.732). The self-citation percentage of A RCHIVOS DE BRONCONEUMOLOGIA was 18.3% and the immediacy index was 0.033. CONCLUSIONS: The impact factor obtained by ARCHIVOS DE BRONCONEUMOLOGIA confirms its importance in Spanish medicine and validates its inclusion as a source journal in Science Citation Index and Journal Citation Report. |
