Abstract

Introduction A large proportion of new HIV diagnoses are incident and hospitalised. HIV testing can be accessed by various means. HIV incidence in UK men who have sex with men (MSM) continues to increase. HIV testing is an important public health intervention to reduce incidence. Locally we have a high prevalence (8:1000) and an HIV cohort of 2300 mainly MSM.

Methods New diagnoses from January- December 2015 were identified from our local database, clinical records were examined. Data was collected on patient characteristics, medical history, results, the method and location of testing.

Results There were 57 new diagnoses; 50 (88%) MSM, 4 (7%) heterosexual females and 3 (5%) heterosexual males. 24 (42%) had tested negative in the previous year, 24 (42%) more than 1 year ago and 9 (16%) had never tested. Testing locations included: 27 (47%) GUM clinic, 14 (25%) GP, 5 (9%) home test kits, 4 (7%) THT, 3 (5%) inpatient, 2 (3.5%) hospital outpatients, 1 (1.75%) sauna and 1 (1.75%) private clinic. Reasons for testing encompassed: 17 (30%) GUM screening, 10 (18%) HIV symptoms, 2 (4%) post exposure prophylaxis, 2 (4%) partner notification, 2 (4%) malignancy, 1 (2%) assault, 1 (2%) condom break, 1 (2%) intravenous drug use and 1 (2%) insurance. 12/49 (24%) avidity results were incident. 10/57 (18%) were hospitalised within 3 months of diagnosis; 3 malignancies, 2 opportunistic infections (Pneumocystis, Mycobacterium avium complex), 1 STI (Shigella), 1 abscess, 1 seroconversion, 1 treatment toxicity and 1 for investigations.

Discussion/conclusion Locally a large proportion of new HIV diagnoses are incident, MSM and hospitalised. Continued innovation is vital in community and hospital admission testing to reduce undiagnosed HIV and incidence.
