A re-audit of individuals with a late diagnosis of HIV in 2016 and 2019 in Greater Manchester

Background: New late HIV diagnosis (CD4 count <350cells/mm³) are higher in North West England compared to the UK average. A Greater Manchester-wide audit into individuals diagnosed with late or very late HIV was conducted in 2016 and re-audited in 2019. Our aim was to gain intelligence into key demographics of late diagnosed individuals across Greater Manchester, review opportunities for earlier diagnosis and determine if key recommendations from the 2016 audit were followed.

Methods: Individuals were identified from locally kept data or HIV and AIDS Reporting System (HARS) data. A retrospective case note review was performed for each patient using data from local notes, General Practice summary of care records and relevant clinical letters. Data was collected for 2019 and compared to 2016 results.

Results: In 2016, nine departments contributed data and 104 individuals were identified as having been diagnosed late. In 2019, seven departments contributed data and 65 individuals were identified as having been diagnosed late. In both years, a greater proportion of males diagnosed late were White British and for females Black African. A greater proportion of late diagnosis occurred in men who have sex with men (MSM) and in heterosexual females. In 2019, a greater proportion of patients had an AIDS-defining illness at time of diagnosis. Whilst in 2016, most patients were asymptomatic. Over one third of patients had a clinical indicator disease in their past medical history, which is an increase in proportion from 2016. The proportion of cases where clinicians felt that there had been probable missed opportunities for earlier diagnosis also increased in 2019.

Conclusions: There are continued missed opportunities for earlier diagnosis. We recommend targeted interventions for groups at higher risk of late presentation, education in primary/secondary care regarding clinical indicator conditions, a formal review process for all late diagnosed cases, communication with primary/secondary care if missed opportunities are identified and broader HIV testing especially in high prevalence areas.
