Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Over a 12-month period, clinical staff at each site will be prompted by participating viral hepatitis nurses/nurses/investigators at the start of each clinic session to adopt a universal screening approach of all new and existing CHB patients for HDV infection. This approach will be supported by the provision of written educational material that will be placed in clinic rooms and clinician folders.

Written prompt :
FOR ALL PHYSCICIANS – Double Reflex Testing for Hepatitis D
Patients with chronic hepatitis B should be screened at least once for hepatitis D co-infection.
Current recommendations:
- Test all HbsAg positive individuals for HDV antibody at least once
- Test HDV RNA in all HDV antibody positive individuals

An electronic prompt within the centralised laboratory testing system will also encourage clinicians to adopt this universal screening approach and perform HDV RNA testing on all HDV seropositive participants. All new CHB patients entering tertiary care at each site will be issued blood forms for HDV testing prior to their initial clinic appointments.

EMR prompt :
Consistent with an acute or chronic infection with hepatitis D virus (HDV). To assess for active infection, HDV NAT testing is recommended. Please send a dedicated 10mL EDTA (lavender top) sample requesting HDV NAT.
