Can Telemedicine Optimize the HCV Care Cascade in People Who Use Drugs? Features of an Innovative Decentralization Model and Comparison with Other Micro-Elimination Strategies

SIMPLE SUMMARY: The global fight against the hepatitis C virus (HCV) involves the processes of micro-elimination of populations at risk. People who use drugs (PWUDs) represent a viral reservoir, due to the historical challenge in treating this population. In particular, the difficulties in the linkage to care of these patients, as well as low adherence to therapies and follow-up and the risk of re-infection make PWUDs a “difficult-to-treat” population. In view of this, the testing of effective management and treatment models for chronic HCV infection in PWUDs is crucial for promoting its elimination. Telemedicine could be a successful solution in the integration and decentralization of care services. ABSTRACT: People who use drugs (PWUDs) are a crucial population in the global fight against viral hepatitis. The difficulties in linkage to care, the low adherence to therapy, the frequent loss to follow-up and the high risk of re-infection make the eradication process of the hepatitis C virus (HCV) really hard in this viral reservoir. Several management and treatment models have been tested with the aim of optimizing the HCV care cascade in PWUDs. Models of decentralization of the care process and integration of services seem to provide the highest success rates. Giving this, telemedicine could favor the decentralization of diagnostic-therapeutic management, key for the implementation of linkage to care, reduction of waiting times, optimization of adherence and results and reduction of the costs. The purpose of this literature review is to examine the role and possible impact of telemedicine in optimizing the HCV care cascade, comparing the different care models that have shown to improve the linkage to care and therapeutic adherence in this special population.
