HIV testing in Black Ethnic Groups (n=287)
HIV testing in heterosexual men (n=2078)
HIV testing in MSM (n=219)
HIV testing in women (n=2131)
Hepatitis C antibody testing 566 of 4420 cases (13%, 4-57%) tested (8 known to have hep C antibody) MSM: 89 of 219 MSM (41%, 0-100%) tested (none known to have hep C antibody)
Conclusions High overall rates of testing with BASHH CEG first line recommended tests for chlamydia, syphilis and HIV High overall rates of testing for gonorrhoea in women when NAATs included Important number of cases having N. gonorrhoeae NAATs, including urine GC NAATs (45% MSM) Urethral microscopy ~ 20% men Cervical microscopy ~ 10% Most MSM tested for HepB (80%) Predominance of hepatitis C testing in MSM
Suggested Areas for Practice Improvement/Interventions Increased documentation of discussion about oral and anal sex, as recommended in the BASHH recommendations on sexual history taking to identify which anatomical sites need to be sampled for infection Regional strategies should be considered to balance nucleic acid amplification testing for gonorrhoea with culture testing to monitor antibiotic sensitivity Increased screening for hepatitis B in MSM is needed in some regions. Increased screening for HIV is needed in some regions, particularly for women
