Abstract
In Japanese hospitals, patients undergoing invasive procedures or surgery are screened for anti-HCV antibodies; however, the majority of possible HCV careers are not referred to hepatologists. In addition to the conventional alert email system, a hepatologist extracted monthly lists of anti-HCV-antibody-positive patients who had been tested two months previously and checked medical records to determine whether the doctors who ordered the tests had properly dealt with the positive results. If the doctors had not yet properly followed up, the hepatologist would send emails to both the doctor and a medical clerk to inform them to conduct an HCV-RNA test and to refer HCV-RNA-positive patients to hepatologists. In total, 130 patients managed in the pre-intervention period and 151 patients managed in the post-intervention period were included in this study. The number of anti-HCV-positive patients whose results were not properly handled showed a significant decrease after the introduction of the double alert system (p = 0.034). Among patients undergoing screening anti-HCV antibody testing, a significant number of patients with probable chronic HCV hepatitis were overlooked by the email alert system and their results were not properly handled. The double alert system was useful for reducing the number of positive anti-HCV antibody patients whose results were not properly handled.
