PURPOSE: To investigate the views of North American and European anesthesiologists on the value of the impact factor (IF). METHOD: Four hundred thirty-eight anesthesiologists in Canada, the United States of America (USA), and Europe were polled about the importance of the IF regarding hiring, promotions, funding of research and to express their personal views. RESULTS: IF of a candidate's publications is a criterion in 38% of academic appointments in Canada and USA vs 81% in Europe (P <0.0001). The importance of IF to obtain funding is greater in Europe (46%) than in North America (17%) (P <0.0001). Twenty-three percent and 50% of Canadian and American anesthesiologists respectively believe that IF affects financial support (P=0.0389). European anesthesiologists value the IF more than the North Americans (67% vs 31%, P <0.0001). Forty-five percent, 67%, and 56% of the Canadian, American and European anesthesiologists respectively estimate that IF reflects journal quality. Sixty-four percent of anesthesiologists in North America vs 81% in Europe (P=0.0175) pursue to publish in high IF journals. Eighty-six percent, 85% and 90% of the Canadian, American and European anesthesiologists believe that the IF of a journal can be manipulated. Finally, 79%, 67%, and 81% of the Canadian, American, and European anesthesiologists believe that IF should be improved but 33%, 35%, and 30% believe that it should be abandoned. CONCLUSIONS: IF for academic appointments and funding is more important in Europe than in North America. More than 50% of anesthesiologists agree that IF needs to be improved.
