Background: Opt-out Emergency Department blood borne virus (EDBBV) screening was introduced at the Royal Free Hospital under the NHSEI (NHS England and NHS Improvement) programme to expand opt-out testing in local authority areas with high HIV prevalence. This initiative was part of the "Toward Zero" policy towards ending HIV transmission in England by 2030.
Methods: All patients attending the Royal Free Hospital Emergency Department (ED) aged 16 and over were screened for blood borne viruses (HIV/HBV/HCV) unless they opted out. We looked at HIV data from patients seen in ED between the initiation of EDBBV testing on the 12th of April and 12th of August 2022. Hepatitis B and C data was reviewed in a separate study.
Outcome: A total of 12,208 samples from 10,641 patients were screened for HIV. Amongst these samples there were 88 which were positive, giving a seroprevalence of 0.84 %. There were 48 patients who were already known to local HIV services, 35 were known to HIV services outside of our Trust and 5 were new diagnoses.
Conclusion: Our results confirmed our local HIV prevalence to be very high, as per the UK Health Security Agency and supports the need for HIV testing. Opt-out ED BBV screening has been a highly effective method for identifying people living with HIV who are unaware of their status.
