BACKGROUND This study aimed to discover the common cause of non-variceal upper-gastrointestinal bleeding (NVUGIB) by conducting a multi-center retrospective study from 2008 to 2012. MATERIAL AND METHODS Hospitalized patients ages ≥18 years old, from 8 hospitals in China, diagnosed with NVUGIB by endoscopy from 1 January 2008 to 31 December 2012 were enrolled. Questionnaires were developed and a data-entry graphical user interface was designed by using EpiData software. RESULTS Total of 2977 hospitalized patients from 8 medical centers were included. A total of 95.47% (2842/2977) of patients were admitted to a general ward, 3.53% (105/2977) were admitted to an emergency ward, and 1.00% (31/2977) were admitted to an intensive care unit. Peptic ulcer remained the most common cause of NVUGIB (73.26%), but there was a declining trend in its constituent ratio, from 2008 to 2012. A total of 14.41% (429/2977) of patients had co-morbid conditions, 92.85% (2764/2977) used proton-pump inhibitors (PPIs) prior to endoscopic treatment, 19.65% (585/2977) underwent emergency endoscopy, and 23.45% (698/2977) received a transfusion of red blood cell suspensions. A total of 5.34% (159/2977) underwent endoscopic therapy, with a treatment rate of 16.9% in high-risk peptic ulcer patients (96/568). A total of 7.69% (237/2977) were administered aspirin, of whom 32.50% (77/237) resumed aspirin intake after gastrointestinal bleeding was controlled. The median length of hospitalization was 8 days (IQR, 5-11) and the mortality rate was 1.71% (51/2977). CONCLUSIONS Peptic ulcer was still the most common cause of NVUGIB in China. The proportion of patients with high-risk peptic ulcer bleeding who received endoscopic therapy was 16.9%. Only 19.65% of NVUGIB patients underwent emergency endoscopy.
