Treatment initiation rates of patients with positive anti-hepatitis C virus results in tertiary hospitals in Turkey: a retrospective, cross-sectional chart review (Lost-C Study)

Background: The aim of this national, multicenter, cross-sectional, retrospective chart review study was to determine the rate of patients in Turkey who received hepatitis C virus (HCV) treatment after receiving positive anti-HCV results during HCV screening. Methods: Data related to patients’ demographics, laboratory results, the time interval from obtaining a positive anti-HCV result to treatment initiation, the specialty of the physician requesting anti-HCV screening, and type of hospital were collected and analyzed. Results: Among 1000 patients who received a positive anti-HCV result, 50.3% were male and 78.5% were screened for HCV-RNA. Among HCV-RNA screened patients, 54.8% (n = 430) had a positive result. Among patients testing positive for HCV-RNA, 72.8% received HCV treatment in line with their positive anti-HCV results. The median time from obtaining a positive anti-HCV result to initiation of HCV treatment was 91.0 days (interquartile range 42.0 to 178.5). Non-surgical branches requested HCV-RNA testing more frequently than surgical branches (p < 0.001). The rate of access to HCV treatment was higher in patients screened in university hospitals than in patients screened in training and research hospitals (p < 0.001). Conclusions: Our results indicate a higher rate of treatment initiation in patients with HCV infection than is described in the published literature. Furthermore, the time from screening to treatment initiation was considerably shorter compared with other international studies. However, because HCV-RNA testing was not requested in a significant portion of patients with a positive test result for anti-HCV, there might be a large patient population with HCV who do not receive treatment.
