This mixed-methods study will utilize qualitative and quantitative methods to achieve its three primary aims. To address aim 1, qualitative interviews will be used to collect data that will inform the initial implementation and re-versioning of a web-based BAI for use in two HCV clinics located at the Palo Alto and San Francisco. To address aim 2, the investigators will use a randomized, hybrid (type 1) design with patient level clinical outcome data and formative evaluation data collected to examine the effectiveness of the web-based BAI. "Hybrid" designs also integrate formative evaluation into experimental designs to identify factors that impact the effectiveness of implementation efforts. Formative evaluation (e.g., site visits, clinic observation, and interviews with staff and patients) will be used to improve the adoption of the web-based BAI at both sites and to provide evidence-based guidance to the investigators' CREATE operational partners for nationwide implementation. To address aim 3, the investigators will conduct a budget impact analysis to estimate the short-term costs (1-3 years) of adoption and diffusion of the web-based BAI and the trajectory of health care spending for study participants. The investigators plan to collect several types of utilization data, including outpatient, inpatient, and pharmacy utilization, and calculate total dollars.
