Most Cited Authors in the Field of Clinical Medicine: A Concentration on Its Transdisciplinary Relations in ISI*

There are numerous research projects in the field of medicine every year, however only few of them are so important that are frequently cited by others. In the current research, the most cited authors, organizations and countries which had an outstanding role in advancing clinical medicine during 1981-91 are identified. The relationship and coverage of the results for clinical medicine and other disciplines has also been investigated. This research is a descriptive work in which the Highly-cited, a product of ISI, is used as a tool for gathering the required data. The data have then been analyzed using MS-Excel. ISI has introduced 265 researchers from 16 countries as the most cited authors in the field of clinical medicine. United States with 200 (75.47%) authors comes first followed by UK with 28 (10.57 %) and Japan with 7 (2.64%) authors. Two universities in the United States, Texas and California universities, with 15 and 11 authors, had the first and second positions respectively. Sixty authors (22.64%) out of 265 were also introduced as the most cited researchers in non-clinical medicine. These researchers were also identified as preeminent researchers in another eight subfields with “Immunology” having the highest share. The findings show that the most efficient authors are from United States, so that their impact factor is 3.9 and 22.2 times greater than that of the European and Asian countries respectively
