The benefits of a public pharmacist service in chronic hepattis C treatment: The real-life results of sofosbuvir-based therapy.

Background: In Brazil, the sofosbuvir-based therapy was introduced in the public health system (SUS) in 2015 to treat Chronic Hepatitis C (CHC). This drug and other direct-acting antiviral agents (DAAs) represent a major advance in the HCV-infection treatment due to their high effectiveness and tolerability. However, the drug safety profile is limited by significant drug interactions and its use is restricted for their high cost. Pharmacists have the opportunity to improve patient care by monitoring the therapy, recommending strategies to guarantee treatment adherence, effectiveness and safety, preventing complications of the disease, and drug-related problems, thus reducing the cost for patients and payers.

Objective: This study aimed to assess the results of the one of the first patient group treated with sofosbuvir in Brazil and their opinions about the benefits of clinical pharmacist services in the achievement of the cure for CHC and in the management of their therapy difficulties.

Methods: This cohort study (November 2015-January 2017) enrolled 240 patients followed up by the clinical pharmacists at the University Pharmacy (UPh) of the Federal University of Santa Catarina, Brazil, during the CHC treatment. The therapeutic schemes used were sofosbuvir + daclatasvir or + simeprevir associated or not with ribavirin. At the end of the therapy, the patients provided qualitative feedback about the clinical pharmacist services.

Results: The study demonstrated high levels of treatment adherence (99.2% of completion rates) and effectiveness rates (Sustained Virological Response rates) (92.1%). Patients reported high levels of satisfaction with the care provided on account of the good rapport built with their pharmacist, the counseling and education on HCV-infection and on sofosbuvir-based therapy utilization, motivation for adherence, and convenient access to the pharmacist.

Conclusions: The clinical pharmacist services provided by the UPh was beneficial to patients treated for CHC with the sofosbuvir-based therapy.
