P77 Undiagnosed HIV: can at risk groups be identified for a new testing strategy?: Abstract P77 Table 1

Abstract

Background/introduction Public Health England report (Nov 2014) the number of HIV tests is increasing, number of positive diagnoses decreasing, but proportion undiagnosed HIV unchanged. We aimed to suggest new local strategy. Demographically identifying late diagnoses (CD4 <350 cells/mm3) would find groups within the population more likely to be diagnosed late. Testing that group could uncover undiagnosed early HIV.Methods Data gathered about HIV diagnosed in our city Jan 2009–Dec 2014: age, gender, ethnicity, orientation, previous test, indication, place tested. Chi-Square compared early/late diagnoses. Under-served compared to well-served demographics.Results 251 new diagnoses in 5 years. 125 early, 126 late.

MSM benefit from specialised clinics yet are <50% diagnoses. Likely public and clinician unawareness of risk excludes earlier testing.
