Abstract
Italian guidelines recommend HIV pre-exposure prophylaxis (PrEP) only upon satisfying strict eligibility criteria. The objective of this study is to evaluate if PrEP candidates attending a community-based service comply with these criteria and whether these prescribing conditions affect retention in care and sexually transmitted infections (STIs) acquisition. A retrospective analysis was performed on PrEP candidates evaluated from January 2019 to June 2022. Data were collected from self-administered questionnaires and clinical files. The population was divided in subjects with 0/1 (0/1 C) and ≥ 2 (≥ 2 C) criteria. Descriptive statistics and non-parametric tests were employed to describe study population. Incidence of PrEP discontinuation and of STIs was estimated per 100 persons-year of follow up (PYFU), and incidence rate ratio (IRR) was calculated. Univariate and multivariable Cox regression analyses were used to evaluate the association strength between PrEP drop out and other variables. The analyses enrolled 659 individuals: 422 individuals were included in 0/1 C, 237 in ≥ 2 C group, respectively. Inconsistent condom use was the most reported prescribing criteria (399 individuals, 60.6%), followed by a previous STI (186 individuals, 28.2%). 0/1 C exhibited lower STIs incidence. PrEP discontinuation was 29% in 0/1 C and 38% in ≥ 2 C (p = 0.031). Cox model revealed that inconsistent condom use was the only prescribing criteria associated to PrEP persistence. The majority of PrEP candidate did not comply with prescribing conditions. Eligibility criteria failed to identify individuals with better retention in care. Our results suggest that Italian guidelines should be updated removing barriers to prescription.
