Healthcare Disparities Identified Between Hmong and Other Asian Origin Groups Living with Chronic Hepatitis B Infection in Sacramento County 2014-2017.

Chronic hepatitis B (CHB) disproportionately affects non-US born Asians. The Hmong have been shown to have the highest rates of CHB and mortality from liver cancer compared to other Asian groups. From September 2014 to September 2017, testing for CHB within Sacramento County was conducted through community-based testing events and an electronic health record alert that identified Asian patients by surname. Demographic and laboratory data were collected for analysis and patients were followed through the study period to assess linkage to care and treatment to compare differences between Asian origin groups. Of 4350 patients tested for CHB, 318 (7.3%) were HBsAg positive, including 90 Chinese, 47 Hmong, and 101 Vietnamese. Hmong were more likely to have Medicaid insurance compared to other Asian origin groups (15%, p < 0.001). Hmong had significantly lower rates of hepatitis B DNA testing (p < 0.001), referral to hepatology (p < 0.001), attendance of first (p < 0.001) and second medical visit (p = 0.0003), and lower rates of antiviral treatment compared to other Asian origin groups. Hmong also had the highest proportion of non-English speakers (p < 0.001). Hmong patients in the Sacramento CHB testing and linkage to care program experience socioeconomic disadvantages compared to Vietnamese and Chinese patients. These factors may contribute to decreased linkage of care and decreased anti-viral treatment rates for CHB.
