Statewide Survey of Primary Care and Subspecialty Providers on Hepatocellular Carcinoma Risk-Stratification and Surveillance Practices.

Abstract

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