10. Missed opportunities to detectprimary HIV infection? Fig 12 • Brighton study: almost all MSM with pharyngitis, fever, rash • HCWs frequently not aware of patient’s sexual orientation • Significance of PHI in driving onward transmission • infectiousness • sexual behaviour 1Shacker, Ann Int Med 1996; 2Weintrob, Ann Int Med 2003; 3Sudarshi, BHIVA 2006

11. Fig 13 • “Pubmed” search; 2000-2007 • “late” or “missed” or “opportunity” “diagnosis” “HIV” “AIDS” • 421 entries • 59 consistent with them Informing clinicians about“Missed HIV” 83% of publications about late HIV diagnosis appeared in HIV/STD/ID/public health journals

12. 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 1Ottewill M et al.

14. 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

15. 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
