Pandemic-Related Disruptions and Hepatocellular Carcinoma Surveillance in Safety-Net Settings.

Abstract

IMPORTANCE: Pandemic-related disruptions in cirrhosis care resulted in major gaps and delays in surveillance for hepatocellular carcinoma (HCC). Whether these initial declines improved and rebounded to prepandemic levels remains unclear. OBJECTIVE: To evaluate contemporary clinical practice data on HCC surveillance utilization from before the COVID-19 pandemic to 4 years after the onset of the pandemic among safety-net populations with cirrhosis. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study was conducted at 5 safety-net health systems in the US. Adults with cirrhosis were evaluated longitudinally across 3 time periods: March 1, 2018, to February 29, 2020 (pre-COVID-19 period), March 1, 2020, to February 28, 2022 (COVID-19 era), and March 1, 2022, to February 29, 2024 (post-COVID-19 period). MAIN OUTCOMES AND MEASURES: The primary outcome was undergoing HCC surveillance identified using Current Procedural Terminology codes for ultrasonography, computed tomography, and magnetic resonance imaging, and corresponding International Statistical Classification of Diseases, Tenth Revision, Clinical Modification diagnosis codes for indication. Comparisons of HCC surveillance across time periods used paired t tests, and comparisons of HCC surveillance between subgroups within the same time period used χ2 tests. RESULTS: Among 6940 patients with cirrhosis, 4001 (57.7%) were men (median [IQR] age, 58 [52-64] years), 206 (3.0%) were Asian, 1720 (24.8%) were Hispanic, 1672 (24.1%) were non-Hispanic Black or African American, and 3081 (44.4%) were non-Hispanic White. The proportion who underwent HCC surveillance within 6 months after diagnosis was 30.8% (1940 patients) in the pre-COVID-19 era, which declined to 21.1% (1468 patients) in the COVID-19 era, and remained at 22.3% (1405 patients) in the post-COVID-19 era. Consistent trends were observed among men and women and among all age and race groups, except for Asian individuals, for whom there was an observed increase in the post-COVID-19 era. Similar trends of low HCC surveillance post-COVID-19 were observed across insurance types but was particularly concerning among uninsured or indigent care covered patients, among whom only 116 of 997 (11.9%) underwent surveillance in the most recent period. CONCLUSIONS AND RELEVANCE: In this observational study of US safety-net populations with cirrhosis, rates of HCC surveillance following pandemic-related declines remained persistently low even up to 4 years after the onset of the COVID-19 pandemic, with fewer than 1 in 4 patients having undergone guideline-concordant HCC surveillance.
