A recent clinical trial demonstrated that a daily dose tenofovir disoproxil fumarate and emtricitabrine (TDF-FTC) can reduce HIV acquisition among men who have sex with men (MSM) and transgender (TG) women by 44%, and up to 90% if taken daily. We explored how medical and service providers understand research results and plan to develop clinical protocols to prescribe, support and monitor adherence for patients on PrEP in the United States.
Using referrals from our community collaborators and snowball sampling, we recruited 22 healthcare providers in San Francisco, Oakland, and Los Angeles for in-depth interviews from May-December 2011. The providers included primary care physicians seeing high numbers of MSM and TG women, HIV specialists, community health clinic providers, and public health officials. We analyzed interviews thematically to produce recommendations for setting policy around implementing PrEP. Interview topics included: assessing clinician impressions of PrEP and CDC guidance, considerations of cost, office capacity, dosing schedules, and following patients over time.
Little or no demand for PrEP from patients was reported at the time of the interviews. Providers did not agree on the most appropriate patients for PrEP and believed that current models of care, which do not involve routine frequent office visits, were not well suited for prescribing PrEP. Providers detailed the need to build capacity and were concerned about monitoring side effects and adherence. PrEP was seen as potentially having impact on the epidemic but providers also noted that community education campaigns needed to be tailored to effectively reach specific vulnerable populations.
While PrEP may be a novel and clinically compelling prevention intervention for MSM and TG women, it raises a number of important implementation challenges that would need to be addressed. Nonetheless, most providers expressed optimism that they eventually could prescribe and monitor PrEP in their practice.
最近的一项临床试验表明,替诺福韦酯富马酸二吡呋酯和恩曲他滨(TDF-FTC)的每日剂量可以使男男性行为者(MSM)和跨性别(TG)女性的 HIV 感染率降低 44%,如果每日服用,最高可降低 90%。我们探讨了医疗和服务提供者如何理解研究结果,并计划制定临床方案,以在美国为接受 PrEP 的患者提供处方、支持和监测依从性。
我们通过我们的社区合作者的推荐和滚雪球抽样,于 2011 年 5 月至 12 月在旧金山、奥克兰和洛杉矶招募了 22 名医疗保健提供者进行深入访谈。这些提供者包括为大量 MSM 和 TG 女性提供服务的初级保健医生、HIV 专家、社区卫生诊所提供者和公共卫生官员。我们对访谈进行了主题分析,以提出制定实施 PrEP 政策的建议。访谈主题包括:评估临床医生对 PrEP 和 CDC 指南的印象、考虑成本、办公室容量、剂量方案以及随时间跟踪患者。
在访谈时,很少有或没有患者对 PrEP 提出需求。提供者对最适合接受 PrEP 的患者没有达成一致意见,他们认为目前的护理模式,不涉及常规频繁的办公室就诊,不适合开 PrEP 处方。提供者详细说明了建立能力的必要性,并对监测副作用和依从性表示关注。PrEP 被认为可能对疫情产生影响,但提供者也指出,需要开展有针对性的社区教育活动,以有效地接触到特定的弱势群体。
虽然 PrEP 可能是一种新颖且具有临床吸引力的 MSM 和 TG 女性预防干预措施,但它提出了一些重要的实施挑战,需要加以解决。尽管如此,大多数提供者还是表示乐观,认为他们最终可以在实践中开处方和监测 PrEP。
