IDDF2023-ABS-0299 Effectiveness of relink initiatives to re-engage diagnosed-but-untreated HCV-positive patients with direct-acting antiviral treatment

Abstract

BackgroundHepatitis C virus (HCV) infection is a major cause of chronic liver disease that can progress to cirrhosis and hepatocellular carcinoma. The WHO has identified HCV infection as a public health threat and set a global target for HCV elimination by 2030. Simple pangenotypic direct-acting antiviral regimens allow most patients to be cured with minimal pretreatment and on-treatment monitoring. To achieve the WHO goal, patients including previously diagnosed HCV-positive patients who have been lost to follow-up, need to be linked to care. Studies report that up to 60% of patients who test positive for HCV antibodies are lost to follow-up and not treated. This loss has been further exacerbated by the COVID-19 pandemic, and many patients put off receiving care. Here, we explore the effectiveness of care re-engagement programs for patients with HCV.MethodsWe assessed ReLink programs (sponsored by Gilead Sciences, Inc.), designed to identify and re-engage HCV-positive patients with medical care and start/restart HCV treatment. We evaluated these programs by analyzing the number of patients, steps in the care cascade where patients were lost to follow-up, and the efficacy of the engagement program (determined by the number relinked and treated).ResultsSix programs assessed 44,964 patient records, identifying 11,163 patients lost to follow-up and eligible for contact. The main reason for the loss of follow-up was the inability to contact patients. Overall, 3726 patients were relinked with care, and 701 were treated. Several key points were identified for improving patient engagement with care, including the use of electronic databases to identify patients lost to follow-up, securing reliable contact information for patients, and partnership with medical societies.ConclusionsActive case finding, patient navigation, and care coordination in these programs led to increased engagement and treatment rates. Engaging HCV-positive patients with care is urgent, as many may already have developed more advanced liver disease. Adopting and adapting effective strategies from these programs may be a feasible way to improve patient outcomes and increase treatment numbers, thus contributing to meeting the WHO goal of HCV elimination.
