Despite high HCV cure rates for those treated in primary care at our FQHC, only a small minority of eligible patients has initiated treatment. Though onsite treatment reduces obstacles related to specialty referral, patient level barriers to HCV evaluation and treatment uptake still exist. IDUs in particular often have limited HCV knowledge, as well as low perceived vulnerability to poor HCV-related health outcomes, low self-esteem and poor self-efficacy, high levels of perceived stigma, and mistrust of healthcare providers.13,14,18 These, as well as other barriers, prevent many IDUs from ever initiating HCV evaluation or starting the treatment uptake process. We therefore propose to test an HCV Group Evaluation and Treatment UPtake (HCV GET-UP) intervention to improve HCV medical evaluation and treatment uptake for HCV and HCV/HIV IDUs within an FQHC. Group-based interventions, often familiar to IDUs, provide social support and encourage behavior change, which together promote enhanced engagement in care. Group-based care can also allow efficient delivery of health-education and medical treatment. Informed by the Information-Motivation-Behavior (IMB) model,19,20 we hypothesize that a group-based HCV intervention, HCV GET-UP, delivered in an FQHC already accessed by patients, will improve HCV treatment uptake by: (1) providing HCV education; (2) increasing motivation by minimizing stigma, and addressing competing priorities and social norms; and (3) increasing self-efficacy and related behavioral skills. We propose the following specific aims:
