Missed opportunities?Chronic Infection:• Secondary Care

– Brighton: 62% of late diagnoses had been seen in secondary care in previous 2 years; 26% with HIV related problem1

• Primary Care– Brighton: 80% of late diagnoses had been seen in primary care

in previous 2 years; 60% with HIV related problem1

• Accident and Emergency– Brighton: 2.5% of those with symptoms consistent with primary

HIV had undiagnosed infection2

Primary HIV Infection:– 71% symptomatic; 51% seen in healthcare; 56% diagnosed –

19% of total3

– 1/680 men aged 18-50 with symptoms of PHI were seroconverting: ?not being blood-tested?2

Effect of knowing HIV statuson sexual behaviour

• Meta-analysis of 11 analyses of sexual behaviour– 6 compared HIV+ “aware” versus HIV+ “unaware”– 5 compared pre- and post- HIV seroconversion– All looked at self-reported rates of unprotected anal or

vaginal intercourse

• UAV 53% (CI 45-60%) lower in those aware versus unaware of HIV+ status– If only considering where partner HIV-, 68% (CI 59-

76%)

Marks et al. JAIDS 2005

Summary

• Earlier diagnosis decreases:– morbidity– mortality– onward transmission

• Routine/opt-out testing is acceptable to patients• Good practice - not to offer a test might be

considered negligent• Pressure from specialists/CMO
