Objectives: To compare the research productivity of different Gulf Cooperation Council (GCC) countries in the field of biomedical sciences from 2011-2013. Methods: This is a retrospective study conducted in the College of Medicine, Alfaisal University, Riyadh, Saudi Arabia. Data on the biomedical publications originating from GCC countries published between January 2011 to December 2013 was searched via MEDLINE using PubMed. The total number of publications emanating from each country was normalized with the country's population. The mean impact factor (IF) of all the publications in a year was calculated for comparative analysis. Results: A total of 11,000 publications were retrieved via MEDLINE using PubMed, out of which, 9222 were selected for analysis. A successive increase in the number of publications by every country was observed. The most striking increase in the number of publications was from Saudi Arabia. However, after normalization with population, the performance of Oman, Qatar, and Kuwait looks far better than Saudi Arabia in terms of research productivity. Data on mean IF showed that the overall mean IF of all GCC countries has remained largely unchanged except Oman. Although Oman had a comparatively low mean IF value in 2011, they recorded a tremendous improvement in successive years. Conclusion: All GCC countries underwent an increase in quantitative research productivity over the last 3 years. However, no increase in quality of research publications was noted based on the proxy reports of mean journal IF.
