ABSTRACT
Articles published by staff of the Faculty of Medicine Siriraj Hospital, which were referred to in international journals during 1991-1995, were retrieved from the Medline database. The citation rates were calculated in terms of reference articles per year and per person per year for each department. The total number of references was 1,185 during the period reviewed, or 192, 180, 235, 288, and 290 times in the year 1991, 1992, 1993, 1994 and 1995 respectively. Accordingly, the citation rates per person per year were calculated to be 0.29, 0.27, 0.35, 0.43 and 0.43 times. The Department of Immunology gained the highest average rate during the dive-year review period, which was 3.71 times per person per year. The Departments of Medicine and Dermatology posted the second and third highest rates which were 1.31 and 1.03 respectively. When the citation rate was calculated separately by per-clinical and clinical departments and year, the citation rates were found be higher for the per-clinical department every year, The average citation rate over the whole five years for the Faculty was 0.35 times per person per year, which indicates an increasing trend when compared with 0.243 times per person per years during 1985-1994.
