ImportanceSurveillance for hepatocellular carcinoma (HCC) in patients with cirrhosis is underused. Identifying potentially modifiable factors to address barriers in HCC surveillance is critical to improve patient outcomes.ObjectiveTo evaluate clinician-level factors contributing to underuse of HCC surveillance in patients with cirrhosis.Design, Setting, and ParticipantsThis survey study included primary care clinicians (PCCs) and gastroenterology and hepatology clinicians at 5 safety-net health systems in the US. Clinicians were surveyed from March 15 to September 15, 2023, to assess knowledge, attitudes, beliefs, perceived barriers, and COVID-19–related disruptions in HCC surveillance in patients with cirrhosis. Data were analyzed from October to November 2023.Main Outcome and MeasuresHCC surveillance knowledge was assessed with 6 questions querying the respondent’s ability to correctly identify appropriate use of HCC surveillance. Attitudes, perceived barriers, and beliefs regarding HCC surveillance and perceived impact of the COVID-19 pandemic–related disruptions with HCC surveillance were assessed with a series of statements using a 4-point Likert scale and compared PCCs and gastroenterology and hepatology clinicians.ResultsOverall, 347 of 1362 clinicians responded to the survey (25.5% response rate), among whom 142 of 237 (59.9%) were PCCs, 48 of 237 (20.3%) gastroenterology and hepatology, 190 of 236 (80.5%) were doctors of medicine and doctors of osteopathic medicine, and 46 of 236 (19.5%) were advanced practice clinicians. On HCC knowledge assessment, 144 of 270 (53.3%) scored 5 or more of 6 questions correctly, 37 of 48 (77.1%) among gastroenterology and hepatology vs 65 of 142 (45.8%) among PCCs (P < .001). Those with higher HCC knowledge scores were less likely to report barriers to HCC surveillance. PCCs were more likely to report inadequate time to discuss HCC surveillance (37 of 139 [26.6%] vs 2 of 48 [4.2%]; P = .001), difficulty identifying patients with cirrhosis (82 of 141 [58.2%] vs 5 of 48 [10.4%]; P < .001), and were not up-to-date with HCC surveillance guidelines (87 of 139 [62.6%] vs 5 of 48 [10.4%]; P < .001) compared with gastroenterology and hepatology clinicians. While most acknowledged delays during the COVID-19 pandemic, 62 of 136 PCCs (45.6%) and 27 of 45 gastroenterology and hepatology clinicians (60.0%) reported that patients with cirrhosis could currently complete HCC surveillance without delays.Conclusions and RelevanceIn this survey study, important gaps in knowledge and perceived barriers to HCC surveillance were identified. Effective delivery of HCC education to PCCs and health system–level interventions must be pursued in parallel to address the complex barriers affecting suboptimal HCC surveillance in patients with cirrhosis.
