Within the last month, AASLD*, IDSA** and IASUSA*** have collaborated to create an updated set of evidence-based guidelines to give healthcare providers a credible, non-biased reference to help guide patient care.2 Current guidelines recommend the collection of a HCV viral genotype to guide regimen and length of therapy selection. The healthcare provider must consider several additional factors to support optimal outcomes, such as comorbidities including co-infection with HIV, renal impairment, depression, history of cardiac, thyroid, transplant and/or autoimmune disease, interferon eligibility status, hematologic and biochemical indices, severity of liver fibrosis, previous response to therapy, applicable genetic polymorphism testing and age. These additional considerations should be evaluated when determining clinical appropriateness of treatment selection and length of therapy.2 Pharmacists caring for HCV patients have the responsibility of making sure these factors are also part of their standard drug utilization review and should collaborate with the prescriber on the collection and review of the patient’s medical history. Pharmacists in a specialty pharmacy setting are more likely to have the ability to invest the time needed to collect and document this information prior to the patient starting treatment. The most appropriate HCV regimen choice is critical but patient commitment to therapy is equally important towards reaching a positive outcome. HCV therapies are often solely self-administered and require strict adherence to therapy in order to reach a SVR goal. A pharmacist should provide the patient with support methods to improve adherence and confidence with therapy. Prior to starting any therapy, a pharmacist, the patient and/or the caregiver should have a consultation session that focuses on objectives to empower a patient to take responsibility for management of their HCV therapy. Clinically, a pharmacist would assess readiness for treatment, evaluate the patient’s treatment expectations, gather additional medical information and educate the patient regarding proper medication administration, storage and all potential side effects and how to manage them. From a non-clinical perspective, it is equally important to evaluate the patient’s support system and need for additional resources before therapy begins. This preliminary conversation helps identify and remove potential barriers to adherence but should also engage the patient to take control of their healthcare needs. Motivational interviewing techniques and the use of open ended questions are often used by pharmacists to help identify 8 adherence risk factors
