Pre-exposure prophylaxis (PrEP) has proven biological efficacy in reducing the risk of sexual acquisition of HIV. Healthcare providers' (HCPs) knowledge of and attitudes to PrEP will be key to successful implementation. In England, PrEP is only available to men who have sex with men (MSM) through the open-label randomized PROUD pilot study of immediate or deferred use.
In September 2013, a cross-sectional survey of UK HCPs distributed through sexual health clinics (219) and professional societies' email lists (2599) and at a conference (80) asked about knowledge of, attitudes to and practice of PrEP.
Overall, 328 of 2898 (11%) completed the survey, of whom 160 of 328 (49%) were doctors, 51 (16%) sexual health advisers (SHAs), 44 (14%) nurses and 73 (22%) unspecified. Over a quarter (83 of 311; 27%) were involved in PROUD. Most respondents (260 of 326; 80%) rated their knowledge of PrEP as medium or high. Over half of respondents (166 of 307; 54%) thought PrEP should be available outside of a clinical trial. The main barriers to supporting PrEP availability outside a clinical trial were concerns about current evidence (odds ratio [OR] 0.13), lack of UK-specific guidance (OR 0.35), concerns about adherence (OR 0.38) and risk of sexual or physical coercion for patients to have condomless or higher risk sex (OR 0.42 in multivariate regression). Just over half (147 of 277; 53%) had been asked about PrEP by patients in the past year, including almost half of those working in a clinic not involved in the PROUD study (86 of 202; 43%).
There is support for PrEP availability outside a clinical trial, but HCPs have residual concerns about its effectiveness and negative consequences, and the absence of UK-specific implementation guidance.
暴露前预防(PrEP)已被证明在降低通过性行为感染艾滋病毒的风险方面具有生物学功效。医疗服务提供者(HCPs)对PrEP的了解和态度将是成功实施的关键。在英国,通过开放标签随机化的立即或延迟使用的PROUD试点研究,PrEP仅提供给男男性行为者(MSM)。
2013年9月,通过性健康诊所(219个)、专业协会的电子邮件列表(2599个)以及一次会议(80个)对英国的医疗服务提供者进行了横断面调查,询问他们对PrEP的了解、态度和实践情况。
总体而言,2898人中328人(11%)完成了调查,其中328人中有160人(49%)是医生,51人(16%)是性健康顾问(SHAs),44人(14%)是护士,73人(22%)未明确职业。超过四分之一(311人中的83人;27%)参与了PROUD研究。大多数受访者(326人中的260人;80%)将他们对PrEP的了解评为中等或高等。超过一半的受访者(307人中的166人;54%)认为PrEP应在临床试验之外可用。支持在临床试验之外提供PrEP的主要障碍包括对当前证据的担忧(比值比[OR] 0.13)、缺乏英国特定的指导(OR 0.35)、对依从性的担忧(OR 0.38)以及患者发生无保护性行为或高风险性行为的性或身体强迫风险(多变量回归中的OR 0.42)。在过去一年中,略多于一半(277人中的147人;53%)的受访者曾被患者问及PrEP,包括在未参与PROUD研究的诊所工作的人中近一半(202人中的86人;43%)。
支持在临床试验之外提供PrEP,但医疗服务提供者对其有效性和负面后果以及缺乏英国特定的实施指导仍存在担忧。
