AASLD guidelines recommend a risk\u2010based screening approach. Our aim was to ascertain if the risk\u2010based approach leads to appropriate HDV screening, identify targets to improve screening rates, and study HDV clinical burden. CHB patients screened for HDV from 01\/2016 to 12\/2021 were identified. Level of training and specialty of providers ordering HDV screening tests were determined. HDV seropositive (HDV+) patient charts were reviewed for the presence of individual risk factors per the AASLD guidelines to determine if they met screening criteria. The severity of liver disease at the time of HDV screening was compared between the HDV+ group and a matched (based on age, hepatitis B e antigen status, BMI and sex) HDV seronegative (HDV\u2212) group. During the study period, 1444\/11,190 CHB patients were screened for HDV. Most screening tests were ordered by gastroenterology (90.2%) specialists and attending physicians (80.5%). HDV+ rate was 88\/1444 (6%), and 72 HDV+ patients had complete information for analysis. 18% of HDV+ patients would be missed by a risk\u2010based screening approach due to unreported or negative risk factors (see Table). A significantly higher number of HDV+ patients had developed significant fibrosis (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0=\u20090.001) and cirrhosis (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u20090.01) by the time of screening than HDV\u2212 (\n                    <jats:italic>n<\/jats:italic>\n                    \u00a0=\u200967) patients. In conclusion, targeted interventions are needed towards trainees and primary care clinics to improve screening rates. Current risk\u2010based criteria do not appropriately screen for HDV. It is time for universal screening of HDV in CHB patients.\n
