Profile name: Proportion of population aged 15 to 24 screened for chlamydia, measured separately in GUM and non-GUM settings

The profile presents a combination of asymptomatic screens and symptomatic tests undertaken as part of the National Chlamydia Screening Programme (NCSP) and includes all tests made in GUM and all other services outside of GUM.

Data corrected 04/07/2011: A number of data errors were identified in the patient residence rates released on the 14/06/2011. Patient residence rates are corrected by Country, SHA and PCT. Data by LA of patient residence remain unchanged. Please ensure that any previously downloaded data are replaced with the current version (04/07/2011).

Profile name:  Proportion of HIV diagnoses where CD4 cell count is < 350 at time of diagnosis

Three surveillance datasets are integrated to form this profile: (i) the Survey Of Prevalent HIV Infections Diagnosed; (ii) HIV and AIDS New Diagnoses Database; and (iii) CD4 Surveillance.  The profile measures the time between infection and diagnosis, shows whether there is a trend towards earlier diagnosis and indirectly informs our understanding of the proportion of HIV infections undiagnosed.  Please contact hiv-sti@hpa.org.uk for further details.  ›› LA map

The definition of a late HIV diagnosis has been updated from a CD4 count <200 cells/mm³ within 91 days of diagnosis to <350 cells/mm³.  This reflects the 2008 BHIVA treatment guidelines which recommend patients should begin anti-retroviral therapy when CD4 cells counts drop <350 cells/mm³.

Profile name:  Uptake of HIV testing among MSM, women and heterosexual men (including those for whom sexual orientation not recorded) measured separately in GUM

This information is taken from the GUMCAD dataset, which is based on all attendances made at GUM clinics. Although GUM services have made significant progress in increasing offer and uptake of HIV testing, in 2009 27% of people left GUM services with their infection still undiagnosed.
