Sexually transmitted infections (STIs) continue to represent a major public health challenge. There is evidence that behavioural interventions to reduce risky sexual behaviours can reduce STI rates in patients attending sexual health (SH) services. However, it is not known if these interventions are effective when implemented at scale in SH settings in England.
The study (Santé) had two main objectives - (1) to develop and pilot a package of evidence-based sexual risk reduction interventions that can be delivered through SH services and (2) to assess the feasibility of conducting a randomised controlled trial (RCT) to determine effectiveness against usual care.
The project was a multistage, mixed-methods study, with developmental and pilot RCT phases. Preparatory work included a systematic review, an analysis of national surveillance data, the development of a triage algorithm, and interviews and surveys with SH staff and patients to identify, select and adapt interventions. A pilot cluster RCT was planned for eight SH clinics; the intervention would be offered in four clinics, with qualitative and process evaluation to assess feasibility and acceptability. Four clinics acted as controls; in all clinics, participants would be consented to a 6-week follow-up STI screen.
SH clinics in England.
Young people (aged 16-25 years), and men who have sex with men.
A three-part intervention package - (1) a triage tool to score patients as being at high or low risk of STI using routine data, (2) a study-designed web page with tailored SH information for all patients, regardless of risk and (3) a brief one-to-one session based on motivational interviewing for high-risk patients.
The three outcomes were (1) the acceptability of the intervention to patients and SH providers, (2) the feasibility of delivering the interventions within existing resources and (3) the feasibility of obtaining follow-up data on STI diagnoses (primary outcome in a full trial).
We identified 33 relevant trials from the systematic review, including videos, peer support, digital and brief one-to-one sessions. Patients and SH providers showed preferences for one-to-one and digital interventions, and providers indicated that these intervention types could feasibly be implemented in their settings. There were no appropriate digital interventions that could be adapted in time for the pilot; therefore, we created a placeholder for the purposes of the pilot. The intervention package was piloted in two SH settings, rather than the planned four. Several barriers were found to intervention implementation, including a lack of trained staff time and clinic space. The intervention package was theoretically acceptable, but we observed poor engagement. We recruited patients from six clinics for the follow-up, rather than eight. The completion rate for follow-up was lower than anticipated (16% vs. 46%).
Fewer clinics were included in the pilot than planned, limiting the ability to make strong conclusions on the feasibility of the RCT.
We were unable to conclude whether or not a definitive RCT would be feasible because of challenges in implementation of a pilot, but have laid the groundwork for future research in the area.

性传播感染(STIs)仍然是一项重大的公共卫生挑战。有证据表明,旨在减少危险性行为的行为干预措施可以降低性健康(SH)服务机构就诊患者的性传播感染率。然而,尚不清楚这些干预措施在英格兰的性健康服务机构大规模实施时是否有效。
该研究(Santé)有两个主要目标——(1)开发并试点一套基于证据的性风险降低干预措施,可通过性健康服务提供;(2)评估开展一项随机对照试验(RCT)以确定相对于常规护理的有效性的可行性。
该项目是一项多阶段、混合方法研究,包括开发阶段和试点随机对照试验阶段。准备工作包括系统评价、国家监测数据分析、分诊算法开发,以及与性健康服务工作人员和患者进行访谈和调查,以识别、选择和调整干预措施。计划在8家性健康诊所开展试点整群随机对照试验;干预措施将在4家诊所提供,并进行定性和过程评估以评估可行性和可接受性。4家诊所作为对照;在所有诊所,参与者将被同意进行为期6周的性传播感染随访筛查。
英格兰的性健康诊所。
年轻人(16 - 25岁),以及男男性行为者。
一个由三部分组成的干预包——(1)一种分诊工具,可以使用常规数据对性传播感染高风险或低风险患者进行评分;(2)一个研究设计的网页,为所有患者提供量身定制的性健康信息,无论风险高低;(3)针对高风险患者基于动机性访谈的简短一对一咨询。
三个结局指标为:(1)干预措施对患者和性健康服务提供者的可接受性;(2)在现有资源范围内实施干预措施的可行性;(3)获取性传播感染诊断随访数据的可行性(全面试验的主要结局指标)。
我们从系统评价中确定了33项相关试验,包括视频、同伴支持、数字化和简短一对一咨询。患者和性健康服务提供者对一对一和数字化干预表现出偏好,提供者表示这些干预类型在他们的机构中可以切实可行地实施。没有合适的数字化干预措施能及时调整用于试点;因此,为了试点目的我们创建了一个占位符。干预包在2家性健康服务机构进行了试点,而不是计划中的4家。发现了干预实施的几个障碍,包括缺乏经过培训的工作人员时间和诊所空间。干预包在理论上是可接受的,但我们观察到参与度较低。我们从6家诊所招募患者进行随访,而不是8家。随访完成率低于预期(16%对46%)。
试点纳入的诊所数量少于计划,限制了就随机对照试验的可行性得出有力结论的能力。
由于试点实施存在挑战,我们无法得出确定性随机对照试验是否可行的结论,但为该领域的未来研究奠定了基础。
