Importance: Surveillance 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., Objective: To evaluate clinician-level factors contributing to underuse of HCC surveillance in patients with cirrhosis., Design, Setting, and Participants: This 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 Measures: HCC 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., Results: Overall, 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 Relevance: In 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.

Background: Timely initiation of antiviral therapy in chronic hepatitis B virus (CHB) reduces risk of disease progression. We evaluate overall treatment rates and predictors of treatment among treatment-eligible safety-net CHB patients., Methods: We retrospectively evaluated adults with CHB from 2010 to 2018 across 4 large safety-net health systems in the United States. CHB was identified with ICD-9/10 diagnosis coding and confirmed with laboratory data. Treatment eligibility was determined using American Association for the Study of Liver Diseases (AASLD) guidelines. Comparison of CHB treatment rates among treatment-eligible patients were performed using χ2 testing, Kaplan Meier methods and log-rank testing. Adjusted multivariate Cox proportional hazards models evaluated independent predictors of receiving treatment among eligible patients., Results: Among 5157 CHB patients (54.7% male, 34.6% African American, 22.3% Asian), 46.8% were treatment-eligible during the study period. CHB treatment rates were 48.4% overall and 37.3% among CHB patients without human immunodeficiency virus. Significantly lower odds of treatment were observed in females versus males (odds ratio: 0.40, 95% confidence interval: 0.33-0.49, P<0.001) and patients age 65 years or above versus age below 45 years (odds ratio: 0.68, 95% confidence interval: 0.51-0.92, P=0.012). Conversely, significantly greater odds of treatment were observed in African American and Asians versus non-Hispanic whites, CHB patients with indigent care versus commercially insured patients, and non-English speaking versus English speaking patients., Conclusion: Among a large multicentered, safety-net cohort of CHB patients, 46.8% of treatment-eligible CHB patients overall and 37.3% of treatment-eligible CHB patients without human immunodeficiency virus received antiviral therapy. Improving CHB treatment rates among treatment-eligible patients represents "low hanging fruit," given the clear benefits of antiviral therapy in mitigating disease progression., (Copyright © 2021 Wolters Kluwer Health, Inc.

Introduction: To evaluate the impact of chronic hepatitis B virus infection (CHB) treatment on risk of cirrhosis, liver-related outcomes, and death among a diverse CHB cohort with a large proportion of African Americans., Methods: Adults with noncirrhotic CHB without human immunodeficiency virus from 2010 to 2018 were retrospectively evaluated across 4 US safety-net health systems. CHB was identified with International Classification of Diseases, Ninth Revision/Tenth Revision diagnosis coding and confirmatory laboratory data. Propensity-score matching, Kaplan-Meier methods, and adjusted Cox proportional hazards models were used to evaluate impact of CHB treatment on risk of cirrhosis, hepatocellular carcinoma (HCC), death, and composite of cirrhosis, HCC, or death., Results: Among 4,064 CHB patients (51.9% female, 42.0% age <45 years, 31.6% African American, 26.6% Asian, 26.7% Hispanic), 23.2% received CHB antiviral therapy and 76.8% did not. Among the propensity score-matched cohort (428 treated and 428 untreated), CHB treatment was associated with lower risk of cirrhosis (hazards ratio 0.65, 95% confidence interval 0.46-0.92, P = 0.015) and composite of cirrhosis, HCC, or death (hazards ratio 0.67, 95% confidence interval 0.49-0.94, P = 0.023). Females vs males and African Americans vs non-Hispanic whites had significantly lower risk of cirrhosis. When treatment effects were stratified by age, sex, and ethnicity, the benefits of antiviral therapies in reducing risk of cirrhosis were seen primarily in CHB patients who were females, age <45 years, and of Asian ethnicity., Discussion: Our propensity score-matched cohort of noncirrhotic CHB patients demonstrated significant reductions in risk of cirrhosis due to CHB treatment., (Copyright © 2021 by The American College of Gastroenterology.)

Alcohol-associated liver disease (ALD) can be coded in United Network for Organ Sharing (UNOS) as either alcoholic cirrhosis or alcoholic hepatitis (AH), without having specific criteria to assign either diagnosis. In this multicenter American Consortium of Early Liver Transplantation for Alcoholic Hepatitis (ACCELERATE-AH) study, we sought to assess the concordance of the clinician diagnosis of AH at liver transplantation (LT) listing versus UNOS data entry of AH as listing diagnosis. In a prior study, consecutive early LT recipients transplanted for AH between 2012 and 2017 were identified by chart review at 10 ACCELERATE-AH sites. In this current study, these same LT recipients were identified in the UNOS database. The primary UNOS diagnostic code was evaluated for concordance with the chart-review assignment of AH. In cases where the primary listing diagnosis in UNOS was not AH, we determined the reason for alternate classification. Among 124 ACCELERATE-AH LT recipients with a chart-review diagnosis of AH, only 43/124 (35%) had AH as listing diagnosis in UNOS; 80 (64%) were listed as alcoholic cirrhosis, and 1 (1%) as fulminant hepatic necrosis. Of the 81 patients missing AH as a UNOS listing diagnosis code, the reasons for alternate classification were 44 (54%) due to a lack of awareness of a separate diagnosis code for AH; 13 (16%) due to concomitant clinical diagnosis of AH and alcoholic cirrhosis in the chart; 12 (15%) due to clinical uncertainty regarding the diagnosis of AH versus acute decompensated alcoholic cirrhosis; and 12 (15%) due to a data entry error. In conclusion, in a large cohort of LT recipients with AH, only 35% were documented as such in UNOS. Increased education and awareness for those performing UNOS data entry, the establishment of specific criteria to define AH in the UNOS database, and the ability to document dates of alcohol use would allow future research on ALD to be more informative., (Copyright © 2019 by the American Association for the Study of Liver Diseases.)

Direct-acting antivirals (DAA) for hepatitis C virus (HCV) became available in 2014, but the role of mental health or substance use disorders (MH/SUD) on access to treatment is unknown. The objective of this study was to examine the extent and predictors of HCV treatment in the pre-DAA and post-DAA periods in four large, diverse health care settings in the United States. We conducted a retrospective analysis of 29,544 adults with chronic HCV who did or did not receive treatment from January 1, 2011, to February 28, 2017. Kaplan-Meier curve was used to examine cumulative risk for receiving HCV treatment stratified by MH/SUD. Predictors of HCV treatment in the pre-DAA (January 1, 2011, to December 31, 2013) and post-DAA (January 1, 2014, to February 28, 2017) cohorts were analyzed using multivariate generalized estimating equations and a modified Poisson model. Overall, 21.7% (2,879/13,240) of those with chronic HCV post-DAA were treated compared with 3.5% (574/16,304) in the pre-DAA period. Compared with non-Hispanic whites, Hispanic whites (adjusted odds ratio [AOR] 0.36; 95% confidence interval [CI], 0.25, 0.52) were less likely to be treated in the post-DAA period. Those with concurrent nonalcoholic fatty liver disease (AOR 1.39; 95% CI, 1.05, 1.83), cirrhosis (AOR 2.00; 95% CI, 1.74, 2.31), and liver transplant (AOR 2.72; 95% CI, 1.87, 3.94) were more likely to be treated post-DAA. Those with MH/SUD were less likely to be treated both before (AOR 0.46; 95% CI, 0.36, 0.60) and after (AOR 0.63; 95% CI, 0.55, 0.71) DAA therapy was available. Overall, the cumulative risk for receiving HCV treatment from 2011 to 2017 among those with versus without MH/SUD was 13.6% versus 21.6%, respectively (P < 0.001). Conclusion: The volume of patients treated for HCV has increased in the post-DAA period, especially among those with liver-related comorbidities, but disparities in access to treatment continue among those with MH/SUD., (© 2018 by the American Association for the Study of Liver Diseases.)

Objective: Despite availability of highly effective direct acting antivirals (DAA), barriers in access to these therapies limit our ability to achieve HCV eradication. We aim to evaluate overall rates and predictors of HCV treatment across four community-based health-care systems focusing on race/ethnicity and insurance-specific disparities., Methods: We retrospectively evaluated all adults with chronic HCV at four health care systems from 1 January 2011 to 28 February 2017, which included a large proportion of ethnic minorities, two safety-net systems, and a broad payer mix across four states. Overall and stratified HCV treatment rates were calculated using Kaplan-Meier methods. Multivariate logistic regression models evaluated for predictors of receiving treatment., Results: Among 29,544 chronic HCV patients (60.5% male, 38.4% black, 8.8% Hispanic, 18.7% Medicaid, 25.9% Medicare, 22.5% private/commercial), overall annual treatment rates were stable from 2011 (0.5%) to 2013 (2.0%), but increased from 2014 (4.8%) to 2017 (16.9%) after availability of DAAs. While similar treatment rates were observed by sex, significantly lower odds of treatment were observed in Hispanics (OR 0.48, 95% CI 0.39-0.60, p < 0.001) compared to non-Hispanic whites and among those with Medicaid (OR 0.21, 95% CI 0.20-0.24, p < 0.001) compared to commercially insured patients., Conclusions: Among our cohort of 29,544 chronic HCV patients, we observed significant improvements in HCV treatment rates after the availability of DAAs in 2014, but overall treatment rates remained <20% in 2017. The lowest rates of treatment were seen among Hispanics and those with Medicaid or indigent care insurance, which is concerning given these are particularly vulnerable populations.
