Changes in the provision of post-exposure prophylaxis for HIV after sexual exposure following introduction of guidelines and publicity campaigns.

In July 2004, British Association of Sexual Health and HIV (BASHH) published guidelines for post-exposure prophylaxis following sexual exposure (PEPSE) and the Terence Higgins Trust (THT) launched a campaign promoting PEPSE among men who have sex with men (MSM). We evaluated subsequent changes in PEPSE attendances. Individuals requesting PEPSE in 2004 were identified from clinic databases. Comparisons of clinical data, exposure characteristics and follow-up were made pre and post campaign. Data were available for 197/216 (91%) PEP attendances. The proportion requesting PEP following sexual exposure increased significantly following the campaign. The majority commencing PEPSE were MSM, with the proportion of MSM increasing significantly from 36/46 (78%) pre to 76/80 (95%) following the campaign. Most prescriptions were in high-risk groups and within guidelines. Times to initiation and completion rates were unchanged. Access to PEPSE following the THT campaign and introduction of BASHH guidelines increased. Promotion of earlier initiation of PEPSE and improvement of completion and follow-up is required.
