A review of HIV postexposure prophylaxis provision at a genitourinary medicine department

We undertook a retrospective case-note audit of all patients who presented to the Edinburgh genitourinary (GU) medicine department following a potential exposure to HIV infection during the period 1 January 2006 to 31 December 2008. Over the audit period, 81 individuals attended the department, in relation to 85 exposure events. Twenty-three (27%) exposures had occurred in a health-care occupational setting and 50 (59%) in a sexual context. Baseline HIV testing was only performed in 38 (45%) of the 85 exposures. Postexposure prophylaxis (PEP) was initiated in 65 (76%) cases: 61 (94%) received the first dose within the recommended 72 hours. In 68 (80%) of the 85 exposures, the PEP initiation decision tallied with guideline recommendations. Fifty-six of the 65 individuals started on PEP continued beyond 72 hours; 53 of them were reviewed at least once during the course of PEP and had routine blood monitoring performed. Documentation regarding adherence was poor, with only 31 having this recorded in notes. Thirty-seven (66%) individuals who continued on PEP attended for follow-up HIV testing at three months. In summary, the department performed well in some aspects of PEP provision. However, baseline HIV testing and documentation regarding adherence are unsatisfactory and we suggest recommendations to improve this.
