The practice pattern of hepatitis b testing in rheumatoid arthritis patients: A cross-national comparison between US and Taiwan. Lin, T., Hashemi, N., Kim, S. C., Kao Yang, Y., Yoshida, K., Tedeschi, S., Desai, R., & Solomon, D. H. Arthritis Care & Research, March, 2017. doi abstract bibtex OBJECTIVE: The Hepatitis B Virus (HBV) testing rates and patterns in rheumatoid arthritis (RA) patients starting disease modifying anti-rheumatic drugs (DMARDs) have not been well studied. We describe and compare the practice patterns of HBV testing among RA patients in U.S. and Taiwan. METHODS: We conducted a retrospective cohort study including RA patients starting first DMARD in U.S. or Taiwan. The first date patients newly received any DMARD was defined as the index date, and the 1-year period before the index date was the baseline period. HBV testing was defined as any of the following tests 1 year before or after the index date: HBsAg, HBsAb, HBcAb, HBeAg, HBeAb or HBV DNA. We calculated the HBV testing rate by year and used Poisson regression to calculate the testing rate ratio. RESULTS: We identified 14,568 RA patients in U.S. and 46,265 in Taiwan. The overall testing rate was 20.3% in U.S. and 24.5% in Taiwan, and gradually increased over the study period from 13.1% to 23.0% in the U.S. and 16.8% to 30.0% in Taiwan. More than one type of HBV test was used in 43.4% in the U.S. and 16.3% in Taiwan patients receiving tests. Results of Poisson regression found Taiwan had a 17% higher testing rate over U.S. during the follow-up period (crude rate ratio: 1.17; 95%CI 1.12-1.22). CONCLUSION: We found small differences in the HBV testing rates across U.S. and Taiwan. Although the rate gradually increased in the past decade, it remained low in both countries.
