医療機関における肝炎ウイルス検査と陽性者拾い上げ対策の現状―千葉県の肝疾患専門医療機関を対象としたアンケート調査結果より―

抄録

A questionnaire survey of medical institutions Chiba Prefecture, Japan, specializing in liver diseases was conducted. This study aimed to provide an overview of the current hepatitis virus tests situations and measures taken to link test-positive individuals to specialists. The positivity rate in these institutions was high, with 2.2% for hepatitis C antibody (HCVAb) and 0.9% for hepatitis B surface antigen (HBsAg). Although many institutions (70%) had been employing linking measures, the consultation rate with hepatologists was low, with 7.6% and 14.3% for HCVAb- and for HBsAg-positive cases, respectively. Only half of the institutions disclosed that their measures were working well. These data suggested the importance of improving the system for determining test-positive individuals and promoting hepatologist consultation.
