8.3 Citation impact
Figure 8.3.1 presents the number of publications and citations and the field normalised citation score for each institution in relation to the world average. Data refers to the latest 5-year period 2006-2010. The field normalised citation score or “citation score” is the relative number of citations to publications of an institution compared to the world average of citations to publications of the same time period and scientific subject field. The normalisation was applied at the level of each publication according to the 253 NSI scientific subject fields. In the case that a publication was attributed to several subject fields, a mean value of the fields was calculated. The citation score was calculated using software that EKT developed. A value greater than 1, indicated that the impact of publications was higher than the world average.
The citation score was the highest for the G. PAPAGEORGIOU General Hospital/ G. PAPAGEORGIOU and equal to the world average. Other hospitals with citation scores above 0.90 were the IPPOKRATEIO General Hospital of Thessaloniki (0.93), the G. Papanikolaou General Hospital of Thessaloniki (0.92) and G. Gennimatas General Hospital of Athens (0.92).
