A decline in the proportion of articles published by American authors in medical journals has been reported. We therefore sought to determine whether the contributions of authors from the United States to the three leading anesthesia journals changed between the years 1980 to 2000. The journals Pain, Anesthesiology, and Anesthesia & Analgesia were selected for evaluation on the basis of their respective impact factors. All clinical studies and basic science studies published in the years 1980, 1985, 1990, 1995, and 2000 were evaluated. The country of origin of the lead author of each article was determined by two of the investigators. ² Tests and least squares linear regression analyses were used to determine associations between the source of publication (United States or abroad) and year of publication. The proportion of American publications in the leading anesthesia specialty journals was found to be decreasing over the period 1980–2000 because of an increase in the rate of publication from abroad that is disproportionate to the increase in the total number of publications in the journals over that time. The reasons for changes in anesthesia-related publications by American authors were not established by this study. The authors speculate that multiple factors are involved, including an increased emphasis on clinical care over research because of economic constraints, American publication in journals other than the leading specialty journals, and the increased quality of submissions from abroad.

IMPLICATIONS: In the period 1980–2000, there was an increase in the number of research articles published in the three main anesthesia journals: Anesthesiology, Anesthesia & Analgesia, and Pain. Despite this increase in research activity, there was a significantly disproportionate decrease in the United States versus non-US authorship.
