Primary Objective: To determine the effectiveness of a protocol-based integrated care model for increasing treatment rates and the number of patients with successful antiviral treatment as measured by an increase in percentage of all new HCV patients achieving a sustained virologic response (SVR). We hypothesize that this model will increase the proportion of patients who are fully evaluated for treatment, who initiate treatment, and who complete treatment compared with patients that receive usual care. Secondary Objectives: Assess the effects of an integrated care model on patient involvement in care (appointment attendance) and PROs (substance abuse, depression, anxiety). We hypothesize that veterans managed with the integrated care model will have better attendance at HCV clinic appointments, have improved rates of drug and alcohol abstinence, and fewer psychological symptoms.
