1. Background
2. Methods
• Recent studies show that at least 2 per 1000 people in the greater Dublin area have been diagnosed with
HIV infection.
• Prevalence rates for Hepatitis C infection in Ireland have varied in previous studies from 0.5-1.2%.
• True Hepatitis B prevalence rate in Ireland is unknown,
• Given the recent improvement in treatment options for HIV and Hepatitis C and sustained late
presentation of new HIV diagnoses, Emergency Medicine, Infectious Diseases, Hepatology and
Laboratory Medicine collaboratively proposed a universal screening programme for the above 3 infections
as a pilot study.
• An opt-out screening program for Blood Borne Viruses (BBV) including HIV antibody, Hepatitis B surface
antigen and Hepatitis C antibody was introduced in March 2014 in our Emergency Department.
• All patients undergoing blood sampling in the department as part of routine clinical care were offered
serological testing for the above viral panel.
• The primary aim of our study was is to assess feasibility and acceptability of this screening approach. A
secondary aim was to describe prevalence rates of both new and known HIV, HBV and HCV infections
• Targets for uptake of BBV panel in those who had bloods drawn were set at 50% for month 1 and 2 and 80%
from month 3 onwards.
3. Results
• Over the first 20 weeks of testing, results of screening 5299 patients were obtained.
• A sustained target rate of >50% was obtained after week 3.

4. Conclusion
• A high feasibility and acceptability rate has been achieved at an early point in this study with sustained
target uptake rates of higher than 50% achieved.
• The overall prevalence of HIV was 11.9/1000, HBV 4.7/1000 and HCV 54.2/1000
• The HIV prevalence found has supported recent data and an unexpectedly high rate of new diagnoses
for HBV and HCV has been found.
• High HCV prevalence rates amongst emergency department attendees are noted with a difference in
linkage to care rates in this virus group.
• These results suggest a roll out to widespread ED testing in urban areas and general practice is
warranted.
• Panel testing may be more effective for this purpose.

•The majority (79%) of patients with known Hepatitis C are now re-linked to care as a result of
the study team intervention.
•Those with newly diagnosed Hepatitis C are being actively followed up on an ongoing basis.
