AIM: To investigate physicians’ knowledge including chronic hepatitis B(CHB) diagnosis, screening, and management in various stages of their training.METHODS: A voluntary 20-question survey was administered in Santa Clara County, CA where Asian and Pacific Islanders(API) account for a third of the population. Among the 219 physician participants,there were 63 interns, 60 second-year residents, 26 chief residents and 70 attending physicians. The survey asked questions regarding respondents’ demographics,general hepatitis B virus knowledge questions(i.e.,transmission, prevalence, diagnostic testing, prevention,and treatment options), as well as, self-reported practice behavior and confidence in knowledge.RESULTS: Knowledge about screening and managing patients with CHB was poor: only 24% identified the correct tests to screen for CHB, 13% knew the next steps for patients testing positive for CHB, 18% knew the high prevalence rate among API, and 31% knew how to screen for liver cancer. Wald chi-square analysis determined the effect of training level on knowledge; in all cases except for knowledge of liver cancer screening(p = 0.0032), knowledge did not significantly increase with length in residency training or completion of residency.CONCLUSION: Even in a high-risk region, both medical school and residency training have not adequatelyprepared physicians in the screening and management of CHB.
