    背景:手术试验的数量正在增加,但此类试验的实施可能很复杂,并提出了具体的挑战。一个多中心,第三阶段,比较颈椎后路椎间孔切开术与颈椎前路椎间盘切除术和融合术治疗颈臂痛(FORVAD试验)的RCT无法招募目标。在试验结束期间进行了快速定性研究,以了解参与FORVAD试验的医疗保健专业人员的经验。目的是为该领域未来的研究提供信息。
    方法:对参与FORVAD试验的18名医疗保健专业人员进行了半结构化访谈。访谈探讨了FORVAD试验参与者的经验。进行了快速定性分析,由规范化过程理论提供信息。
    结果:数据分析中产生了四个主要主题:(1)个人与社区平衡;(2)试验设置和交付;(3)识别和接近患者;和(4)随机分组的时间安排。FORVAD试验的目标对参与者来说是有意义的,他们支持关于两种FORVAD干预措施存在临床或集体平衡的观点;然而,许多外科医生有治疗偏好,缺乏个体平衡。招募最成功的网站采用了更结构化的程序来识别和招募患者,而其他采用更多“临时”筛查策略的网站则难以识别患者。手术当天的随机化在某些地点引起了医学法律和实际问题。
    结论:神经外科手术试验的组织和实施是复杂的,并提出了许多挑战。站点经常报告招聘人数很少,并讨论了进行复杂的外科手术RCT的后勤问题。未来的神经外科试验可能需要在设置过程中提供更多的灵活性和时间,以最大限度地增加招聘人数的机会。规范化过程理论提供的快速定性分析能够快速确定试验实施的关键问题,因此快速定性分析可能是团队在试验中进行定性研究的有用方法。

    BACKGROUND: The number of surgical trials is increasing but such trials can be complex to deliver and pose specific challenges. A multi-centre, Phase III, RCT comparing Posterior Cervical Foraminotomy versus Anterior Cervical Discectomy and Fusion in the Treatment of Cervical Brachialgia (FORVAD Trial) was unable to recruit to target. A rapid qualitative study was conducted during trial closedown to understand the experiences of healthcare professionals who participated in the FORVAD Trial, with the aim of informing future research in this area.
    METHODS: Semi-structured interviews were conducted with 18 healthcare professionals who had participated in the FORVAD Trial. Interviews explored participants\' experiences of the FORVAD trial. A rapid qualitative analysis was conducted, informed by Normalisation Process Theory.
    RESULTS: Four main themes were generated in the data analysis: (1) individual vs. community equipoise; (2) trial set-up and delivery; (3) identifying and approaching patients; and (4) timing of randomisation. The objectives of the FORVAD trial made sense to participants and they supported the idea that there was clinical or collective equipoise regarding the two FORVAD interventions; however, many surgeons had treatment preferences and lacked individual equipoise. The site which had most recruitment success had adopted a more structured process for identification and recruitment of patients, whereas other sites that adopted more \"ad hoc\" screening strategies struggled to identify patients. Randomisation on the day of surgery caused both medico-legal and practical concerns at some sites.
    CONCLUSIONS: Organisation and implementation of a surgical trial in neurosurgery is complex and presents many challenges. Sites often reported low recruitment and discussed the logistical issues of conducting a complex surgical RCT. Future trials in neurosurgery may need to offer more flexibility and time during set-up to maximise opportunities for larger recruitment numbers. Rapid qualitative analysis informed by Normalisation Process Theory was able to quickly identify key issues with trial implementation so rapid qualitative analysis may be a useful approach for teams conducting qualitative research in trials.

    OBJECTIVE: This study aims to test the feasibility and acceptability of a group-based pelvic floor muscle training for pregnant women in China and facilitate women\'s adherence to the pelvic floor muscle training programme.
    BACKGROUND: Urinary incontinence is a prevalent health problem in women worldwide, especially in pregnant women. Supervised pelvic floor muscle training is recommended as the first-line conservative treatment for urinary incontinence. However, the implementation and effectiveness of pelvic floor muscle training are limited by insufficient human resources and low adherence. Group-based interventions may improve people\'s adherence to interventions by facilitating peer support. However, it has been investigated in a limited number of maternity studies.
    METHODS: Feasibility testing randomized controlled trial, accompanied by a mixed methods process evaluation.
    METHODS: This study was guided by the Medical Research Council framework for complex interventions and the Behaviour Change Wheel guide to developing interventions. A three-phase, mixed-methods design was used in this study. This study reported the feasibility of the group-based pelvic floor muscle training programme. Semi-structured reviews were conducted following the intervention to explore the acceptability of the programme.
    RESULTS: The study included 48 pregnant women with a recruitment rate of 52.17%. The adherence rate to the training programme was 66.67%. The intervention was positively valued, in particular the support promoting participants\' adherence, but additional changes need to be made to the programme for a future trial.
    CONCLUSIONS: Group-based pelvic floor muscle training programme provides a possible way of delivering pelvic floor muscle training with limited health professionals in China. The study showed promising results concerning the acceptability and feasibility of the intervention, which were well perceived by both pregnant women and the midwife.
    CONCLUSIONS: Group-based pelvic floor muscle training may have the potential of reducing the prevalence of urinary incontinence in pregnant women with insufficient healthcare professionals.
    CONCLUSIONS: This study assessed the feasibility of delivering group-based pelvic floor muscle training in pregnant women in China. The group-based pelvic floor muscle training is acceptable to both pregnant women and the midwife, but integrating online and face-to-face sessions need to be considered. The findings of this study provided evidence for delivering group-based pelvic floor muscle training to pregnant women in China.
    UNASSIGNED: The study has adhered to CONSORT guidelines (Table S1) and TIDier checklist (Table S2).
    UNASSIGNED: The patient and public have been invited as stakeholders during the development of the intervention. They worked with healthcare professionals to co-design the group-based pelvic floor muscle training programme.
    BACKGROUND: The trial was registered on ClinicalTrials.gov (NCT05242809) under the title \'Development and Feasibility Testing of a Group-based PFMT Programme for Antenatal Women in Nanjing City in China\'.

    BACKGROUND: In the UK, recent evidence of young people and gambling indicates a higher prevalence of gambling in comparison to other addictive behaviours. Engaging in gambling-related behaviour at a young age is associated with short and long-term consequences, including financial, emotional, academic, interpersonal, and physical and mental health detriments; otherwise known as gambling-related harms (GRH). Given the unique vulnerability of this younger group, early interventions aimed at delaying or preventing gambling are critical. PRoGRAM-A (Preventing Gambling-Related Harm in Adolescents) is a school-based, social network intervention to protect young people from future GRH, by delaying or preventing gambling experimentation.
    METHODS: Pilot cluster RCT with an embedded process evaluation and health economic scoping study.
    METHODS: PRoGRAM-A will be delivered in four schools, with two control schools acting as a comparator. All are secondary schools in Scotland. Baseline surveys were conducted with students in S3 (ages 13-14). Follow-up surveys were conducted with the same cohort, six months post-baseline.
    METHODS: PRoGRAM-A trainers will deliver a 2-day, out-of-school training workshop to Peer supporters. Peer supporters will be nominated by peers among their school year group (S3, age 13-14). Workshops will provide peer supporters with information on four gambling-related topics: (1) what is gambling? (2) gambling and gaming, (3) gambling marketing, (4) identifying harm and reducing risk. Peer supporters will disseminate the information (message diffusion) they have learned among their friends and family over a 10-week period. After the 2-day workshop, PRoGRAM-A trainers will conduct × 3 in-school follow-up sessions with peer supporters to offer support, encouragement, and advice to Peer Supporters as well as monitor and explore the extent of their message diffusion.
    METHODS: The primary outcome of the pilot cluster RCT (cRCT) will be whether progression to a phase III RCT is justified.
    CONCLUSIONS: This will be the first pilot cluster RCT (cRCT) of an intervention to prevent gambling-related harms among young people within the UK. If findings indicate feasibility and acceptability, funding will be sought for a phase III RCT of effectiveness.

    背景:这项研究证明了在“每个人一起实现更多身体活动”(TEAM-PA)随机对照试验中,如何使用形成性过程评估来评估实施并提高剂量和保真度。TEAM-PA使用随机组队列设计来评估基于组的干预措施对增加非裔美国女性体力活动的功效。
    方法:干预小组开会10周,由非裔美国女性主持人共同领导,由小组反馈组成的干预会议,健康课程,以团体为基础的体育活动游戏,和基于群体的目标设定。从多元理论框架出发,干预措施采用协作性和竞争性群体策略,以社会隶属关系为目标,包括关注基于群体的行为技能的基本要素,对等积极沟通,集体主义,最优挑战,社会便利,和点对点挑战。形成性过程评估用于监测范围,剂量,和忠诚,并实施反馈和解决方案。
    结果:在两个队列中,四组(n=54)随机接受TEAM-PA干预.平均每周有84.8%的参与者参加,超出了先验标准。系统观察的结果表明,平均每个疗程完成了93%的剂量项目,并且在促进者和小组水平上都达到了足够的保真度。参与者遵守FitBits(6.73±0.42天/周),大多数参与者成功地实现了基于小组的目标。开放式项目的使用也表明需要对基于群体的PA游戏进行额外的修改,包括允许个人休息,结合更广泛的练习,最大限度地减少需要在没有帮助的情况下弯曲/向下伸展的活动,并为主持人提供实施游戏的额外培训。初步证据表明,这些变化成功地提高了参与者对队列1(M=1.83,SD=0.71)到队列2(M=3.33,SD=0.69)的游戏理解。
    结论:这项研究的结果表明,剂量,和忠诚,同时还强调了实施可在身体健康水平上访问的竞争性基于小组的PA游戏的策略。形成过程评估,包括开放式项目和协作头脑风暴,在改善未来干预措施方面具有巨大潜力。
    背景:本研究于2022年8月22日在Clinicaltrials.gov(#NCT05519696)上注册,然后于2022年9月12日招募第一名参与者(https://clinicaltrials.gov/study/NCT05519696?term=N0CT5519696&rank=1)。
    BACKGROUND: This study demonstrates how formative process evaluation was used to assess implementation and improve dose and fidelity in the Together Everyone Achieves More Physical Activity (TEAM-PA) randomized controlled trial. TEAM-PA uses a randomized group cohort design to evaluate the efficacy of a group-based intervention for increasing physical activity among African American women.
    METHODS: Intervention groups met for 10 weeks and were co-led by female African American facilitators, with intervention sessions consisting of group feedback, a health curriculum, group-based physical activity games, and group-based goal-setting. Drawing from a multi-theoretical framework, the intervention targeted social affiliation using collaborative and competitive group strategies, including essential elements focused on group-based behavioral skills, peer-to-peer positive communication, collectivism, optimal challenge, social facilitation, and peer to peer challenges. Formative process evaluation was used to monitor reach, dose, and fidelity, and implement feedback and solutions.
    RESULTS: Across two cohorts, four groups (n = 54) were randomized to the TEAM-PA intervention. On average 84.8% of participants attended each week, which exceeded the a priori criteria. Results from the systematic observations indicated that on average 93% of the dose items were completed in each session and adequate levels of fidelity were achieved at both the facilitator and group-levels. Participants were compliant with wearing the FitBits (6.73 ± 0.42 days/week) and most participants successfully contributed to meeting the group-based goals. The use of open-ended items also revealed the need for additional modifications to the group-based PA games, including allowing for individuals to take breaks, incorporating a broader range of exercises, minimizing activities that required bending/reaching down without assistance, and providing facilitators with additional training for implementing the games. Initial evidence suggests that these changes were successful in increasing participants\' comprehension of the games from Cohort 1 (M = 1.83, SD = 0.71) to Cohort 2 (M = 3.33, SD = 0.69).
    CONCLUSIONS: Findings from this study demonstrated high levels of reach, dose, and fidelity, while also highlighting strategies for implementing competitive group-based PA games that are accessible across physical fitness levels. Formative process evaluation, including open-ended items and collaborative brainstorming, holds tremendous potential for improving future interventions.
    BACKGROUND: This study was registered on Clinicaltrials.gov (# NCT05519696) on August 22, 2022 prior to the enrollment of the first participant on September 12, 2022 ( https://clinicaltrials.gov/study/NCT05519696?term=NCT05519696&rank=1 ).

    There is a need for careful examination of large volumes of collected (structured and unstructured) information related to school-based evaluation. There is also no published, comprehensive framework/s for evaluating complex interventions in Irish primary schools. The aim of this paper is to outline a methodology for process evaluation of an Irish primary school-based physical activity (PA) and nutrition intervention. Evaluation followed the three themes outlined by the British Medical Research Council: implementation, context, and mechanism of impact that we further divided into six dimensions. Methodological tools included questionnaires, PA logs, reflective journals, write and draw, and semi-structured interviews. We triangulated findings across these multiple tools to assess each dimension. We designed a unique framework to enable comparisons and offer researchers a template for evaluating complex health promotion interventions in primary schools. We present a methodology for evaluating a complex school-based health promotion intervention. The framework we propose integrates process and outcome data. It aims to enhance future result interpretation and facilitate informed comparisons among intervention schools.

    预防青少年吸烟是一个重大的公共卫生优先事项,吸烟在职业学校尤其普遍。实施良好的全面学校烟草政策以及预防措施显示出减少吸烟的潜力,但是实施过程对于实现预期效果至关重要。我们调查了在丹麦职业教育和培训的学生中4-5个月后,多组分吸烟预防干预措施的实施保真度是否以及如何影响学生吸烟结果(全国年龄范围15-65岁,平均25.6)和预备基础教育(全国年龄范围15-25岁,平均17.6)机构使用来自集群RCT的问卷数据。干预措施包括无烟上课时间政策,教育课程,和班级竞争。我们计算了一个整体实施保真度度量,结合了员工报告的学校水平交付(保真度)和学生报告的收据(参与,响应能力),并使用多水平回归模型分析与吸烟结果的关联(每天吸烟,定期,和上学时间)。我们用有限三次样条回归来补充分析。此外,我们按学校类型对分析进行了分层,并分析了单独干预组成部分的实施保真度与吸烟结局之间的关联.高执行率与正常吸烟(OR:0.37,95%CI:0.18-0.78)和上学时间吸烟的几率较低相关,但不是每天吸烟,这些关联在学校环境之间有所不同。当单独分析时,组件的实施保真度对结局没有显著影响.我们的发现强调需要支持学校烟草政策干预措施的实施过程,以确保减少学生吸烟的预期效果。
    Preventing young people\'s cigarette smoking is a major public health priority, and smoking is especially prevalent in vocational schools. Well-enforced comprehensive school tobacco policies accompanied by preventive efforts show potential to reduce smoking, but the implementation process is crucial to achieve the intended effect. We investigate whether and how implementation fidelity of a multi-component smoking prevention intervention impacted student smoking outcomes after 4-5 months among students in Danish vocational education and training (national age range 15-65 years, mean 25.6) and preparatory basic education (national age range 15-25 years, mean 17.6) institutions using questionnaire data from a cluster-RCT. The intervention included a smoke-free school hours policy, educational curriculum, and class competition. We calculated an overall implementation fidelity measure combining staff-reported school-level delivery (fidelity) and student-reported receipt (participation, responsiveness), and used multilevel regression models to analyze associations with smoking outcomes (smoking daily, regularly, and during school hours). We supplemented the analysis with restricted cubic spline regression. Additionally, we stratified the analyses by school types and analyzed associations between implementation fidelity of the separate intervention components and smoking outcomes. High implementation was associated with lower odds of regular smoking (OR: 0.37, 95% CI: 0.18-0.78) and smoking during school hours, but not daily smoking, and these associations varied between the school settings. When analyzed separately, implementation fidelity of the components did not affect the outcomes significantly. Our findings underline the need to support the implementation process of school tobacco policy interventions to ensure the intended effects of reducing students\' smoking.

    辅助内分泌治疗(AET)降低早期乳腺癌的死亡率,但坚持率很低。我们开发了一种多成分干预措施来支持AET的依从性,包括:短信,信息传单,接受和承诺疗法(ACT),和副作用网站。在多阶段优化策略的指导下,在ROSETA初步优化试验中对干预组件进行了测试.我们的混合方法过程评估研究了组件的可接受性。中试优化试验使用24-1分数阶乘设计。52名服用AET的女性被随机分配到八个实验条件之一,包含独特的组件组合。随机化后4个月进行可接受性问卷,与20名参与者的半结构化访谈进一步探讨了可接受性。评估以可接受性理论框架的四个结构为指导:情感态度,负担,感知的有效性,和连贯性。对定量和定性结果进行了三角测量,以确定协议/分歧。总体可接受性评分较高(中位数=14-15/20,范围=11-20)。当进行三角测量时,定性和定量结果之间存在一致性。大多数参与者“喜欢”或“强烈喜欢”所有组件,并报告他们需要很少的努力才能参与。50%(单张)至65%(短信)"同意"或"强烈同意,“很明显,每个组件将如何帮助坚持。感知的有效性好坏参半,35.0%(短信)至55.6%(ACT)的参与者“同意”或“强烈同意”每个组件都能提高他们的依从性。访谈数据提供了改进建议。这四种成分对于患有乳腺癌的女性来说是可以接受的,并且将被改进。混合方法和三角测量是有用的方法学方法,可用于其他优化试验过程评估。
    Adjuvant endocrine therapy (AET) reduces mortality in early-stage breast cancer, but adherence is low. We developed a multicomponent intervention to support AET adherence comprising: text messages, information leaflet, acceptance and commitment therapy (ACT), and side-effect website. Guided by the multiphase optimization strategy, the intervention components were tested in the ROSETA pilot optimization trial. Our mixed-methods process evaluation investigated component acceptability. The pilot optimization trial used a 24-1 fractional factorial design. Fifty-two women prescribed AET were randomized to one of eight experimental conditions, containing unique component combinations. An acceptability questionnaire was administered 4 months post-randomization, and semi-structured interviews with 20 participants further explored acceptability. Assessments were guided by four constructs of the theoretical framework of acceptability: affective attitude, burden, perceived effectiveness, and coherence. Quantitative and qualitative findings were triangulated to identify agreements/disagreements. There were high overall acceptability scores (median = 14-15/20, range = 11-20). There was agreement between the qualitative and quantitative findings when triangulated. Most participants \"liked\" or \"strongly liked\" all components and reported they required low effort to engage in. Between 50% (leaflet) and 65% (SMS) \"agreed\" or \"strongly agreed,\" it was clear how each component would help adherence. Perceived effectiveness was mixed, with 35.0% (text messages) to 55.6% (ACT) of participants \"agreeing\" or \"strongly agreeing\" that each component would improve their adherence. Interview data provided suggestions for improvements. The four components were acceptable to women with breast cancer and will be refined. Mixed-methods and triangulation were useful methodological approaches and could be applied in other optimization trial process evaluations.

    在马里进行的主动社区案件管理(ProCCM)审判通过取消使用费来加强了两个方面的卫生系统,专业社区卫生工作者(CHW),以及升级的初级保健中心(PHCs)和随机的乡村集群,以接受CHW(干预)的主动家访或被动CHW(对照)的固定站点服务。在双臂上,患病儿童的24小时治疗和孕妇的四次或更多产前检查翻了一番,五岁以下儿童的死亡率减半,与基线相比超过三年。在干预臂中,积极的CHW家访对儿童的治疗和妇女的产前保健利用有适度的影响,但对五岁以下儿童死亡率没有影响,与控制臂相比。我们旨在通过检查实施情况来解释这些结果,机制,以及双方的背景。我们使用混合方法融合设计进行了过程评估,其中包括在两个时间点与提供者和参与者进行的79次深入访谈,与195家供应商进行的调查,和临床数据的二次分析。我们以新颖的方式嵌入了现实主义的方法来测试,精炼,巩固关于ProCCM工作原理的理论,生成三个级联展开的上下文干预行为者机制结果节点。首先,取消用户费用并在每个集群中部署专业CHW,使参与者能够迅速寻求卫生部门的护理,并创造了便利获取的环境。第二,卫生系统对所有CHW和PHC的支持实现了公平,尊敬的,优质医疗保健,动机增加了,快速利用。第三,积极的CHW家访促进CHW和参与者提供和寻求护理,建立关系,信任,和期望,但是这些机制在两个臂中也被激活。解决护理的多重结构性障碍,去除使用费,专业CHWs,升级后的诊所与提供者和患者机构互动,以实现双方的快速护理和儿童生存。积极主动的家访加速或复合了各种机制,这些机制被激活并改变了各种情况。
    The Proactive Community Case Management (ProCCM) trial in Mali reinforced the health system across both arms with user fee removal, professional Community Health Workers (CHWs), and upgraded primary health centres (PHCs)-and randomized village-clusters to receive proactive home visits by CHWs (intervention) or fixed site-based services by passive CHWs (control). Across both arms, sick children\'s 24-hour treatment and pregnant women\'s four or more antenatal visits doubled, and under-five mortality halved, over three years compared to baseline. In the intervention arm, proactive CHW home visits had modest effects on children\'s curative and women\'s antenatal care utilization, but no effect on under-five mortality, compared to the control arm. We aimed to explain these results by examining implementation, mechanisms, and context in both arms. We conducted a process evaluation with a mixed method convergent design that included 79 in-depth interviews with providers and participants over two time-points, surveys with 195 providers, and secondary analyses of clinical data. We embedded realist approaches in novel ways to test, refine, and consolidate theories about how ProCCM worked, generating three context-intervention-actor-mechanism-outcome nodes that unfolded in a cascade. First, removing user fees and deploying professional CHWs in every cluster enabled participants to seek health sector care promptly and created a context of facilitated access. Second, health systems support to all CHWs and PHCs enabled equitable, respectful, quality healthcare, which motivated increased, rapid utilization. Third, proactive CHW home visits facilitated CHWs and participants to deliver and seek care, and build relationships, trust, and expectations, but these mechanisms were also activated in both arms. Addressing multiple structural barriers to care, user fee removal, professional CHWs, and upgraded clinics interacted with providers\' and patients\' agency to achieve rapid care and child survival in both arms. Proactive home visits expedited or compounded mechanisms that were activated and changed the context across arms.

    背景:全面性教育(CSE)对于解决青少年的负面性健康和生殖健康(SRH)结局至关重要。然而,在包括赞比亚在内的许多低收入和中等收入国家,对这种影响知之甚少,CSE实施的现实,教学质量和内容的全面性。
    方法:我们的方法是通过过程评估获得的,其中包括欧洲专家组关于评估性教育计划的指南和医学研究理事会(MRC)过程评估指南的建议。CSE实施的开发过程和质量分别使用八个和六个质量标准进行评估。深度访谈(IDI)焦点小组讨论(FGD),采用文档分析和课堂观察来评估情境因素,CSE的实施过程和影响机制。在64名有意选择的参与者中,对每组7名学生进行了深入访谈(50)和焦点小组讨论(2)。样本包括学生(35),来自九所中学的家长(4人)和教师(17人)(四所郊区,四个城市和一个农村),决策者(4),宗教领袖(4)。我们采用演绎内容分析来分析数据。
    结果:影响CSE实施的背景因素包括:(1)CSE计划的零碎资金;(2)学校缺乏监测计划;(3)缺乏社区参与;(4)宗教和社会文化障碍;(5)缺乏教授CSE的技能和能力;(6)CSE的时间分配不足。对CSE发展质量的评估显示:(1)缺乏性别多样性;(2)学生没有有意义地参与计划的执行;(3)在计划执行过程中缺乏利益相关者的参与;(4)缺乏性别敏感性;(5)缺乏人权方法。对CSE实施质量的评估显示:(1)没有基于技能的CSE教学的证据;(2)社区中CSE和SRH服务之间没有联系;(3)在CSE教学过程中缺乏多种交付方法的结合。CSE的影响机制与学生SRH实践的可接受性和积极变化有关。
    结论:CSE实施过程中情境因素的复杂影响突出了介入设计过程中情境分析的必要性。通过利益相关者的参与共同创建CSE计划可以减少社会反对,并使文化敏感的CSE成为可能。全面的教师培训,指导课程以及设置适当的监测工具和指标可能会提高CSE实施的质量。
    BACKGROUND: Comprehensive sexuality education (CSE) is critical in addressing negative sexual and reproductive health (SRH) outcomes among adolescents. Yet in many low- and middle-income countries (LMICs) including Zambia, little is known about the impact, realities of CSE implementation, the quality of teaching and the comprehensiveness of the content covered.
    METHODS: Our approach was informed by a process evaluation incorporating recommendations by the European Expert Group guidance on evaluating sexuality education programmes and the Medical Research Council (MRC) guidelines on process evaluation. The development process and quality of CSE implementation were assessed using eight and six quality criteria respectively. In-depth interviews (IDIs), focus group discussions (FGDs), document analysis and classroom observation were employed to assess contextual factors, implementation process and mechanisms of impact of CSE. In-depth interviews (50) and focus group discussions (2) with seven pupils in each group were conducted among 64 purposefully selected participants. The sample comprised pupils (35), parents (4) and teachers (17) from nine secondary schools (four peri-urban, four urban and one rural), policymakers (4), and religious leaders (4). We employed deductive content analysis to analyse the data.
    RESULTS: Contextual factors that influenced the implementation of CSE included: (1) piecemeal funding for the CSE programme; (2) lack of monitoring programmes in schools; (3) lack of community engagement; (4) religious and socio-cultural barriers; (5) lack of skills and competency to teach CSE; and (6) insufficient time allocation for CSE. The assessment of the quality of the development of CSE revealed: (1) a lack of sexual diversity; (2) no meaningful participation of pupils in programme implementation; (3) a lack of stakeholder engagement during programme implementation; (4)  lack of gender sensitivity; and (5) lack of human rights approach. Assessment of the quality of the implementation of CSE revealed: (1) no evidence of skill-based CSE teaching; (2) no linkage between CSE and SRH services in the communities; and (3) a lack of incorporation of multiple delivery methods during CSE teaching. The mechanisms of impact of CSE were related to the acceptability and positive changes in pupils\' SRH practices.
    CONCLUSIONS: The complex influences of contextual factors during CSE implementation highlight the need for contextual analysis during the interventional design. Co-creation of the CSE programme through stakeholder participation could reduce social opposition and enable a culturally sensitive CSE. Comprehensive teacher training, a guiding curriculum as well as setting of appropriate monitoring tools and indicators are likely to enhance the quality of CSE implementation.

    背景:POINCARE-2试验旨在评估一种旨在通过每日称重和随后的治疗措施解决危重患者体液超负荷的策略的有效性。即使在高度标准化的护理环境中,比如重症监护病房,这种复杂干预措施的有效性取决于其实际有效性,也取决于其实施程度。使用过程评估,我们旨在提供对实施的理解,context,以及试验过程中POINCARE-2策略变化的机制,了解其有效性,并告知有关干预措施传播的决定。
    方法:我们遵循医学研究理事会指南进行了混合方法过程评估。这两个定量数据都来自试验,并使用来自与专业人士的半结构化访谈的定性数据来解释实施,POINCARE-2战略的变化机制,以及潜在影响战略实施的环境因素。
    结果:在对照期间,该策略的实际暴露分数为29.1%至68.2%,干预期间从61.9%上升到92.3%,表明了潜在的污染和对策略的次优保真度。缺乏适当的称重装置,缺乏专门用于研究的人力资源,审判前根深蒂固的处方习惯,和预期的战略知识已被确定为在试验背景下最佳实施战略的主要障碍。
    结论:POINCARE-2策略的污染和次优保真度都引起了人们对意向治疗(ITT)分析无效的潜在偏见的担忧。然而,最佳保真度似乎是可以实现的。因此,临床策略不应仅基于ITT分析的阴性结果而被拒绝.我们的研究结果表明,即使在高度标准化的护理条件下,临床策略的实施可能受到许多环境因素的阻碍,这表明了评估干预措施可行性的至关重要性,在对其有效性进行任何评估之前。
    背景:编号NCT02765009。
    BACKGROUND: POINCARE-2 trial aimed to assess the effectiveness of a strategy designed to tackle fluid overload through daily weighing and subsequent administration of treatments in critically ill patients. Even in highly standardized care settings, such as intensive care units, effectiveness of such a complex intervention depends on its actual efficacy but also on the extent of its implementation. Using a process evaluation, we aimed to provide understanding of the implementation, context, and mechanisms of change of POINCARE-2 strategy during the trial, to gain insight on its effectiveness and inform the decision regarding the dissemination of the intervention.
    METHODS: We conducted a mixed-method process evaluation following the Medical Research Council guideline. Both quantitative data derived from the trial, and qualitative data from semi-structured interviews with professionals were used to explain implementation, mechanisms of change of the POINCARE-2 strategy, as well as contextual factors potentially influencing implementation of the strategy.
    RESULTS: Score of actual exposure to the strategy ranged from 29.1 to 68.2% during the control period, and from 61.9 to 92.3% during the intervention period, suggesting both potential contamination and suboptimal fidelity to the strategy. Lack of appropriate weighing devices, lack of human resources dedicated to research, pre-trial rooted prescription habits, and anticipated knowledge of the strategy have been identified as the main barriers to optimal implementation of the strategy in the trial context.
    CONCLUSIONS: Both contamination and suboptimal fidelity to POINCARE-2 strategy raised concerns about a potential bias towards the null of intention-to-treat (ITT) analyses. However, optimal fidelity seemed reachable. Consequently, a clinical strategy should not be rejected solely on the basis of the negativity of ITT analyses\' results. Our findings showed that, even in highly standardized care conditions, the implementation of clinical strategies may be hindered by numerous contextual factors, which demonstrates the critical importance of assessing the viability of an intervention, prior to any evaluation of its effectiveness.
    BACKGROUND: Number NCT02765009.
