Abstract

Background: Hepatocellular carcinoma (HCC) surveillance in patients with cirrhosis is associated with improved survival. Provision of HCC surveillance is low in the US, particularly in primary care settings.

Aims: To evaluate current hepatitis C virus (HCV) and HCC surveillance practices and physician attitudes regarding HCC risk-stratification among primary care and subspecialty providers.

Methods: Using the Tailored Design Method, we delivered a 34-item online survey to 7654 North Carolina-licensed internal/family medicine or gastroenterology/hepatology physicians and advanced practice providers in 2022. We included the domains of HCV treatment, cirrhosis diagnosis, HCC surveillance practices, barriers to surveillance, and interest in risk-stratification tools. We performed descriptive analyses to summarize responses. Tabulations were weighted based on sampling weights accounting for non-response and inter-specialty comparisons were made using chi-squared or t test statistics.

Results: After exclusions, 266 responses were included in the final sample (response rate 3.8%). Most respondents (78%) diagnosed cirrhosis using imaging and a minority used non-invasive tests that were blood-based (~ 15%) or transient elastography (31%). Compared to primary care providers, subspecialists were more likely to perform HCC surveillance every 6-months (vs annual) (98% vs 35%, p < 0.0001). Most respondents (80%) believed there were strong data to support HCC surveillance, but primary care providers did not know which liver disease patients needed surveillance. Most providers (> 70%) expressed interest in potential solutions to improve HCC risk-stratification.

Conclusions: In this statewide survey, there were great knowledge gaps in HCC surveillance among PCPs and most respondents expressed interest in strategies to increase appropriate HCC surveillance.
