Background: Infectious diseases (ID) physicians are important for hepatitis C virus (HCV) care delivery in Canada. Our study describes their current and intended patterns of practice, attitudes, and barriers to care.
Methods: The study population includes 372 practicing ID physicians who are members of the Association of Medical Microbiology and Infectious Disease (AMMI) Canada. A random sample from each province was invited to participate in a web-based survey. Our outcome of interest was level of HCV care provided, and related intentions for the next 12 months. Additional survey domains included attitudes toward treatment and perceived barriers to care.
Results: Of 205 invitations to complete the survey, 64 (31%) physicians responded to the full survey and 81 to an abbreviated survey on the main outcomes of interest (overall response rate 71%). After adjusting for non-response, we estimate that 38% (95% CI 29% to 46%) are prescribing direct-acting antiviral (DAA) therapy, and 17% (95% CI 9% to 24%) are interested in starting to prescribe. Of full survey respondents, 100% of prescribers and 79% of non-prescribers agreed that people who inject drugs should be offered DAA therapy. Common barriers to care include patients' competing priorities, mental health comorbidities, poor access to harm reduction services, and insufficient physician training.
Conclusions: A large proportion of Canadian ID physicians are not currently prescribing DAA therapy for HCV. While some of these physicians are interested in starting to prescribe, we need strategies to improve physician training and address other barriers to care as provincial restrictions on DAA eligibility are being eliminated.
