| アブストラクト | BACKGROUND: Anticoagulants and/or antiplatelet agents such as acetylsalicylic acid (ASA) are important in prevention of cardiovascular (CV) events, but may be associated with upper gastrointestinal bleeding (UGIB). However, discontinuing these agents may leave patients at risk of CV events. OBJECTIVES: This study aimed to assess patterns of therapy after UGIB in routine clinical practice. METHODS: The Health Improvement Network UK primary care database was used to identify a cohort of patients aged 40-84 years with a UGIB event between 2000 and 2007 (n = 2,036). Patients were followed up for 1 year from the recorded UGIB. Re-prescription rates for antithrombotics and drugs that can modify the risk of UGIB were estimated at 30, 90, 180, and 365 days. RESULTS: At 365 days, the re-prescription rate was 43 % for ASA, 66 % for warfarin, 69 % for clopidogrel, and 49 % for dipyridamole. The re-prescription rate of gastroprotective agents at 365 days for current users of histamine H2-receptor antagonists was 36 % and that of proton pump inhibitors (PPIs) was 97 %. In patients who were prescribed ASA before UGIB (n = 572), only 24 % were prescribed a PPI in the previous year. In patients who were prescribed ASA in the year after UGIB (n = 337), 92 % were prescribed a PPI. CONCLUSIONS: Antiplatelet use fell after UGIB events. In patients who were prescribed a PPI after a UGIB event, there was increased re-prescription of antiplatelet agents and antithrombotics. |
