Objective To study the improvement of interobserver consistency in pathological diag- nosis of chronic gastritis by using a visual-analog scale after the training on diagnostic criteria of chronic gas- tritis. Methods Eight pathologists conducted two rounds of evaluation of 70 slides with confirmed diagnosis of chronic atrophic gastritis. After the first round, every pathologist was trained with the diagnosis criteria from ＂Chinese consensus on chronic gastritis （2012, Shanghai）＂, and the visual analog scale was used in the second round. Eight pathologists were grouped by working experience and hospital, respectively, and the interobserver consistency was evaluated using Kappa analysis. Results The overall Kappa values of 5 kinds of chronic gastritis features improved in the second round when compared with those from the first one. In the second round of diagnosis, the difference in Kappa value between the senior and the junior group was -0. 018 0-0. 034 1, while the interobserver consistency was at the same level. The difference in Kappa value between the same hospital and the different hospital groups was 0. 012 2-0. 049 7, but the interobserver consistency was at the same level for the various chronic gastritis features, expect for H. pylori infection, which was better for the same hospital group. Conclusion Interohserver consistency generally improves after the training of the proposed diagnostic criteria of “Chinese consensus on chronic gastritis （2012, Shang- hai）” accompanied with a visual-analog scale.
