Decline incidence in upper gastrointestinal bleeding in several recent years: data of the Japan claims database of 13 million accumulated patients. J Clin Biochem Nutr 2020; 68:95-100. [PMID: 33536718 PMCID: PMC7844659 DOI: 10.3164/jcbn.20-153] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 09/27/2020] [Indexed: 12/27/2022] Open
Abstract
This study was to examine the recent trends in upper gastrointestinal bleeding in Japan using a large-scale real-world database. The incidence of upper gastrointestinal bleeding was evaluated in the Japan Medical Data Center claims database of 13,019,713 patients aged 20 to 74 years with traceability for 3 months from 2009 to 2014. The incidence was compared with peptic ulcers and gastroesophageal reflux disease. The prescription of medications was also evaluated. The incidence of bleeding was 0.137%, 0.121%, 0.113%, 0.106%, 0.099%, and 0.105% during 2009 to 2014 with a time-dependent decline (p<0.001). Peptic ulcers (>10 times higher than the incidence of bleeding) decreased with time (p<0.001), whereas gastroesophageal reflux disease increased (p = 0.006). Upper gastrointestinal bleeding was higher in male patients and older patients (60–74 years old) (p<0.001 respectively). The prescription rate of antithrombotic medications and proton pump inhibitors increased from 2009 to 2014 (p<0.001 respectively). The incidence of upper gastrointestinal bleeding decreased from 2009 to 2014 in this relatively large-scale real-world database in Japan, concomitant with the decrease in peptic ulcers. The decreased incidence might have been due to changes in the disease structure and therapeutic strategies over time.

Tokushima Y, Tago M, Tokushima M, Katsuki NE, Iwane S, Eguchi Y, Yamashita SI. Management of Hepatitis B Surface Antigen and Hepatitis C Antibody-Positive Patients by Departments Not Specializing in Hepatology at a Suburban University Hospital in Japan: A Single-Center Observational Study. Int J Gen Med 2020; 13:743-750. [PMID: 33061544 PMCID: PMC7534862 DOI: 10.2147/ijgm.s268857] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Accepted: 08/27/2020] [Indexed: 12/25/2022] Open
Abstract
Objective To investigate effects of an altered medical environment between 2010 and 2015 on viral hepatitis treatment behaviors of doctors who were not hepatology specialists. Methods Charts of patients who were identified as hepatitis B surface antigen (HBs-Ag)-positive or hepatitis C virus antibody (HCV-Ab)-positive by university hospital departments not specializing in hepatology from January to December 2015 were retrospectively reviewed. Patients were assigned to a “referred” group or a “non-referred” group based on whether they were subsequently referred to the Hepatology Department. Age, sex, type of department visited (one of various internal medicine departments, or a different department), and blood test results were compared in the two groups. Results Among 7,824 patients screened for HBs-Ag, 82 were positive. Twenty-nine (35.4%) had subsequently been referred to the Hepatology Department, which was higher than the 2010 referral rate (20.6%). In multivariate analysis, patients in the referred group were significantly more likely to have visited one of various internal medicine departments, and they had higher levels of platelet count and γ-glutamyl transpeptidase. Among 7,778 patients screened for HCV-Ab, 279 were positive. Only 33 (11.8%) had subsequently been referred to the Hepatology Department, which was lower than the 2010 referral rate (18.7%). In multivariate analysis, patients in the referred group were significantly more likely to have visited an internal medicine department. Conclusion HCV-antibody-positive patients screened by departments not specializing in hepatology were not managed adequately in 2015. This suggests a need for education of doctors not specializing in hepatology, particularly those not working in internal medicine departments.
