    背景:抗真菌药物管理(AFS)计划被认为有助于优化抗真菌药物的治疗和预防处方。然而,只有少数这样的程序被实施。因此,有关此类计划的行为驱动因素和障碍以及从现有成功的AFS计划中学到的证据有限。这项研究旨在利用英国的大型AFS计划并从中汲取教训。目的是(a)调查AFS计划对处方习惯的影响,(A)使用基于COM-B的理论域框架(TDF)(能力,机会,和行为动机),以定性地识别多个专业的抗真菌处方行为的驱动因素和障碍,(c)半定量调查过去5年抗真菌处方习惯的趋势。
    方法:对血液学进行了定性访谈和半定量在线调查,重症监护,呼吸,剑桥大学医院的实体器官移植临床医生。开发了讨论指南和调查,以确定处方行为的驱动因素,基于TDF。
    结果:来自21/25临床医生的反应。定性结果表明,AFS计划在支持最佳抗真菌处方实践方面是有效的。我们发现了七个影响抗真菌处方决策的TDF域-五个驱动因素和两个障碍。主要驱动因素是多学科团队(MDT)之间的集体决策,而主要障碍是缺乏某些治疗方法和真菌诊断能力。此外,在过去的5年里,跨专业,我们观察到处方集中在更有针对性而非广谱抗真菌药物上的趋势越来越明显.
    结论:了解相关临床医生对已确定的驱动因素和障碍的处方行为的基础,可以为AFS计划的干预措施提供信息,并有助于持续改善抗真菌药物处方。可以利用MDT之间的集体决策来改善临床医生的抗真菌处方。这些发现可能会在专科护理环境中推广。
    BACKGROUND: Antifungal stewardship (AFS) programs are recognized to contribute to optimizing antifungal prescribing for treatment and prophylaxis. However, only a small number of such programs are implemented. Consequently, evidence on behavioral drivers and barriers of such programs and learnings from existing successful AFS programs is limited. This study aimed to leverage a large AFS program in the UK and derive learnings from it. The objective was to (a) investigate the impact of the AFS program on prescribing habits, (a) use a Theoretical Domains Framework (TDF) based on the COM-B (Capability, Opportunity, and Motivation for Behavior) to qualitatively identify drivers and barriers for antifungal prescribing behaviors across multiple specialties, and (c) semiquantitatively investigate trends in antifungal prescribing habits over the last 5 years.
    METHODS: Qualitative interviews and a semiquantitative online survey were conducted across hematology, intensive care, respiratory, and solid organ transplant clinicians at Cambridge University Hospital. The discussion guide and survey used were developed to identify drivers of prescribing behavior, based on the TDF.
    RESULTS: Responses were received from 21/25 clinicians. Qualitative outcomes demonstrated that the AFS program was effective in supporting optimal antifungal prescribing practices. We found seven TDF domains influencing antifungal prescribing decisions-five drivers and two barriers. The key driver was collective decision-making among the multidisciplinary team (MDT) while key barriers were lack of access to certain therapies and fungal diagnostic capabilities. Furthermore, over the last 5 years and across specialties, we observed an increasing tendency for prescribing to focus on more targeted rather than broad-spectrum antifungals.
    CONCLUSIONS: Understanding the basis for linked clinicians\' prescribing behaviors for identified drivers and barriers may inform interventions on AFS programs and contribute to consistently improving antifungal prescribing. Collective decision-making among the MDT may be leveraged to improve clinicians\' antifungal prescribing. These findings may be generalized across specialty care settings.

    背景:在COVID-19大流行期间,病毒检测呈阳性的个体参加了一项研究,48小时内,远程监测他们的生命体征,以表征疾病进展和恢复。在一项名为“关于COVID-19住院的风险分层和早期警报”(RiskSEARCH)的研究中,采用了虚拟试验设计,以降低参与者和研究界的风险。食品和药物管理局批准的带有可穿戴设备的CurrentHealth平台是一种连续的远程患者监测技术,可支持医院的家庭护理,并用作数据收集工具。注册参与者连续佩戴CurrentHealth可穿戴设备长达30天,并通过提供的平板电脑进行每日症状调查。并行进行了定性子研究,以更好地了解虚拟试验的实施,包括参与者的障碍和促进者。
    目的:本研究旨在了解与虚拟护理平台和研究团队进行交互的用户体验的障碍和促进因素,同时使用定性和定量数据参与完全虚拟的研究。
    方法:进行了半结构化访谈,以了解参与者在全球大流行期间参与虚拟研究的经验。时间表包括他们的注册经验以及与设备和研究人员的互动。共有3名RiskSEARCH参与者通过电话接受了采访,并使用主题分析对转录进行感应编码和分析。将主题映射到理论域框架(TDF)上,以识别和描述影响研究依从性的因素。定量指标,包括对作为RiskSEARCH主要研究的一部分收集的可穿戴和计划任务的依从性,与访谈配对,以呈现参与的整体情况。
    结果:所有参与者都超出了我们对完全坚持参与者的定义,并报告说参与是可行的并且负担较低。试验期间症状逐渐缓解。归纳主题分析从访谈数据中确定了13个主要主题,它们被演绎地映射到14个TDF域中的11个,突出每个人的障碍和促进者。
    结论:RiskSEARCH子研究的参与者在整个参与过程中表现出高水平的依从性和参与度。尽管参与者在设置和维护当前健康工具包方面遇到了一些挑战(例如,充电设备),他们报告说,参与的要求既合理又现实。我们证明了TDF可用于归纳主题分析。我们预计在未来的虚拟研究和试验中扩大这项工作,以确定实施的障碍和有利因素。
    BACKGROUND: During the COVID-19 pandemic, individuals with a positive viral test were enrolled in a study, within 48 hours, to remotely monitor their vital signs to characterize disease progression and recovery. A virtual trial design was adopted to reduce risks to participants and the research community in a study titled Risk Stratification and Early Alerting Regarding COVID-19 Hospitalization (RiskSEARCH). The Food and Drug Administration-cleared Current Health platform with a wearable device is a continuous remote patient monitoring technology that supports hospital-at-home care and is used as a data collection tool. Enrolled participants wore the Current Health wearable device continuously for up to 30 days and took a daily symptom survey via a tablet that was provided. A qualitative substudy was conducted in parallel to better understand virtual trial implementation, including barriers and facilitators for participants.
    OBJECTIVE: This study aimed to understand the barriers and facilitators of the user experience of interacting with a virtual care platform and research team, while participating in a fully virtual study using qualitative and quantitative data.
    METHODS: Semistructured interviews were conducted to understand participants\' experience of participating in a virtual study during a global pandemic. The schedule included their experience of enrollment and their interactions with equipment and study staff. A total of 3 RiskSEARCH participants were interviewed over telephone, and transcriptions were inductively coded and analyzed using thematic analysis. Themes were mapped onto the Theoretical Domains Framework (TDF) to identify and describe the factors that influenced study adherence. Quantitative metrics, including adherence to wearable and scheduled tasks collected as part of the RiskSEARCH main study, were paired with the interviews to present an overall picture of participation.
    RESULTS: All participants exceeded our definition of a fully adherent participant and reported that participation was feasible and had a low burden. The symptoms progressively resolved during the trial. Inductive thematic analysis identified 13 main themes from the interview data, which were deductively mapped onto 11 of the 14 TDF domains, highlighting barriers and facilitators for each.
    CONCLUSIONS: Participants in the RiskSEARCH substudy showed high levels of adherence and engagement throughout participation. Although participants experienced some challenges in setting up and maintaining the Current Health kit (eg, charging devices), they reported feeling that the requirements of participation were both reasonable and realistic. We demonstrated that the TDF can be used for inductive thematic analysis. We anticipate expanding this work in future virtual studies and trials to identify barriers and enabling factors for implementation.

    背景:临床试验包括处于试验生命周期各个阶段的多个过程。这些过程通常涉及复杂的行为,例如招募弱势患者人群和临床医生必须成功提供复杂的试验干预措施。很少有研究利用行为框架来评估挑战并制定有效的试验招募和实施试验干预措施的策略。这项研究报告了一种创新的方法学方法的应用,以了解核心试验过程,即招募和干预交付,使用行为科学方法制定旨在减轻试验过程问题的策略。
    方法:UK-REBOA试验旨在评估主动脉内球囊阻断复苏术(一种新型干预措施)对失血出血的损伤患者的临床和成本效益。使用理论知情(理论领域框架,TDF)与UK-REBOA试验的现场工作人员进行半结构化访谈,以检查在试验招募和干预措施交付方面可以改进的试验过程。使用TDF分析访谈,以确定对行为的影响,然后将其映射到行为改变的技术,并发展成为潜在的解决方案。
    结果:试验过程中遇到的挑战的行为诊断突出了与一系列TDF领域相关的因素:技能,环境背景和资源,关于能力的信念,关于后果的信念,社会影响,和记忆,注意,和决策过程。在解决方案开发阶段,我们确定了24种合适的行为改变技术,这些技术已发展成为针对报告的流程问题的建议解决方案,目的是改变行为以改善招募和/或干预交付.建议的解决方案包括对试用培训内容进行有针对性的更改,重组环境的建议(例如,通过提供有关社会和环境后果的信息来加强试验的目的)以及其他减少招募和干预措施障碍的策略.
    结论:这项研究证明了在一项积极的创伤试验中应用行为方法来调查(“诊断”)行为试验过程问题并随后制定和实施有针对性的解决方案(“治疗”)的可行性。了解影响行为的因素,这种创伤试验中的态度和信念使我们能够实施理论上的知情,旨在加强审判实践的循证解决方案。

    BACKGROUND: Clinical trials comprise multiple processes at various stages of the trial lifecycle. These processes often involve complex behaviours such as recruiting vulnerable patient populations and clinicians having to deliver complex trial interventions successfully. Few studies have utilised a behavioural framework to assess challenges and develop strategies for effective trial recruitment and delivery of trial interventions. This study reports the application of an innovative methodological approach to understand core trial processes, namely recruitment and intervention delivery, using a behavioural science approach to develop strategies designed to mitigate trial process problems.
    METHODS: The UK-REBOA trial aims to evaluate the clinical and cost-effectiveness of resuscitative endovascular balloon occlusion of the aorta (a novel intervention) in injured patients with exsanguinating haemorrhage. A behavioural investigation (\'diagnosis\') was conducted using theory-informed (Theoretical Domains Framework, TDF) semi-structured interviews with site staff from the UK-REBOA trial to examine trial processes which could be improved in relation to trial recruitment and delivery of the intervention. Interviews were analysed using the TDF to identify influences on behaviour, which were then mapped to techniques for behaviour change and developed into potential solutions.
    RESULTS: The behavioural diagnosis of the challenges experienced during trial processes highlighted factors relevant to a range of TDF domains: Skills, Environmental context and resources, Beliefs about capabilities, Beliefs about consequences, Social influences, and Memory, attention, and decision-making processes. Within the solution development phase, we identified 24 suitable behaviour change techniques that were developed into proposed solutions to target reported process problems with the aim of changing behaviour to improve recruitment and/or intervention delivery. Proposed solutions included targeted changes to trial training content, suggestions to restructure the environment (e.g. reinforced the purpose of the trial with information about the social and environmental consequences) and other strategies to reduce barriers to recruitment and intervention delivery.
    CONCLUSIONS: This study demonstrates the feasibility of applying a behavioural approach to investigate (\'diagnose\') behavioural trial process problems and subsequently develop and implement targeted solutions (\'treatment\') in an active trauma trial. Understanding the factors that affected behaviour, attitudes and beliefs in this trauma trial allowed us to implement theoretically informed, evidence-based solutions designed to enhance trial practices.

    BACKGROUND: Blood glucose is higher in people working night shifts compared to day workers. Changes to eating behaviour, activity and sleep patterns in addition to circadian disruption are likely to impact glucose management in night-shift workers with type 2 diabetes.
    OBJECTIVE: To investigate current dietary intake and glucose variability during night work, including barriers and facilitators to dietary behaviour in this context.
    METHODS: A mixed-methods case study will be conducted. Shift workers with type 2 diabetes working in a hospital setting will be recruited to this two-part study. Part 1: 70 participants will complete a 10-day observational study collecting data on continuous glucose, diet (self-report diary), sleep and physical activity during a period covering night work, rest days and non-night workdays. Mean glucose concentration and variability, and the mean healthy diet index score, will be compared between days of night work, non-night work and rest, after adjusting for other individual factors (sleep/physical activity/demographics). Part 2: A sample (n~13) will complete semi-structured interviews based on behavioural science frameworks to explore barriers/enablers to dietary behaviour when working night shifts. This will inform a quantitative survey to explore the generalisability of interview findings.
    CONCLUSIONS: Findings from Part 1 and 2 will be triangulated to identify potential intervention strategies to address key barriers and enablers to healthier eating, and in turn improved glucose control, in shift workers with type 2 diabetes. This will be facilitated through stakeholder consultation and application of behavioural science frameworks. Shift-Diabetes study registration: ISRCTN11764942.

    Despite the overwhelming interest in clinical genomics, uptake has been slow. Implementation science offers a systematic approach to reveal pathways to adoption and a theory informed approach to addressing barriers presented. Using case study methodology, we undertook 16 in-depth interviews with nongenetic medical specialists to identify barriers and enablers to the uptake of clinical genomics. Data collection and analysis was guided by two evidence-based behaviour change models: the Theoretical Domains Framework (TDF), and the Capability, Opportunity Motivation Behaviour model (COM-B). Our findings revealed the use of implementation science not only provided a theoretical structure to frame the study but also facilitated uncovering of traditionally difficult to access responses from participants, e.g., \"safety in feeling vulnerable\" (TDF code emotion/COM-B code motivation). The most challenging phase for participants was ensuring appropriate patients were offered genomic testing. There were several consistent TDF codes: professional identity, social influences, and environmental context and resources and COM-B codes opportunity and motivation, with others varying along the patient journey. We conclude that implementation science methods can maximise the value created by the exploration of factors affecting the uptake of clinical genomics to ensure future interventions are designed to meet the needs of novice nongenetic medical specialists.

    Invasive species are considered a major threat for global agricultural production, biodiversity and ecosystem services. Their spread and establishment is mainly influenced by bio-physical factors, but also by people\'s activities such as tourism or farming. Understanding farmers\' behavior is necessary to develop effective control measures. We conducted qualitative semi-structured interviews in south-east Austria to explore factors that facilitate or impede farmers\' behavior to individually or collectively control the invasive Western Corn Rootworm (WCR, Diabrotica virgifera virgifera). We analyze the interview contents using the Capability-Opportunity-Motivation-Behavior model (COM-B model). Our results show that farmers\' motivation and related behavior is influenced by intra- and interpersonal factors such as their knowledge about WCR control measures (capability psychological), perceived societal acceptance of WCR control measures or perceived normative obligations to participate in collective measures (opportunity social). Farmers\' motivation (reflective and automatic) for implementing individual or collective WCR control measures is mainly determined by their perceived self-efficacy, their perceived efficacy of WCR control measures and the perceived severity of WCR damages. Contextual factors such as environmental conditions, legal regulations, the landscape composition, the farm type or financial impacts of WCR control measures (opportunity physical) are essential prerequisites for farmers\' behavior. The results suggest that new modes of knowledge transfer are required to facilitate the proactive implementation of individual and collective WCR control measures prior to trigger events, such as severe WCR damages. The development of a trusting and communicative environment between farmers is key for collective WCR control. Exchange with residents about WCR and applied control measures may help to create a shared understanding and increase societal acceptance. Moreover, a long-term and proactive coordination which meets individual famers\' needs is required to implement collective WCR control measures. Farmers who have successfully implemented individual and collective WCR measures may encourage non-applicants and sceptics by \"learning from peers\".

    Background and Purpose: Little is known about the process of engaging key stakeholders to select and design a knowledge translation (KT) intervention to increase the use of an outcome measure using audit and feedback. The purpose of this case report was to describe the development of a KT intervention designed with organizational support to increase physical therapists\' (PTs) use of a selected outcome measure in an inpatient sub-acute rehabilitation hospital. Case Description: Eleven PTs who worked at a sub-acute rehabilitation hospital participated. After determining organizational support, a mixed methods barrier assessment including a chart audit, questionnaire, and a focus group with audit and feedback was used to select an outcome measure and design a locally tailored intervention. The intervention was mapped using the Theoretical Domains Framework (TDF). One investigator acted as knowledge broker and co-designed the intervention with clinician and supervisor support. Outcomes: The 4-m walk test was selected through a group discussion facilitated by the knowledge broker. Support from the facility and input from the key stakeholders guided the design of a tailored KT intervention to increase use of gait speed. The intervention design included an interactive educational meeting, with documentation and environmental changes. Discussion: Input from the clinicians on the educational meeting, documentation changes and placement of tracks, and support from the supervisor were used to design and locally adapt a KT intervention to change assessment practice among PTs in an inpatient sub-acute rehabilitation hospital. Implementation and evaluation of the intervention is underway.

    实施临床试验的治疗部门通常需要改变医疗保健实践。这种变化的障碍可能会破坏治疗的实施,使试验更有可能证明没有治疗效果。“个性化透析液温度的主要结果”(MyTEMP)是一项集群随机试验,将在安大略省的84个血液透析中心进行,加拿大将调查在每次血液透析开始时测得的患者体温以下0.5°C的个体化透析温度(IDT)的主要结果是否存在差异。与36.5°C的标准透析温度相比。为了告知如何在许多血液透析中心部署IDT,我们评估了血液透析医生和护士使用IDT的感知障碍和促成因素。
    我们使用理论域框架(TDF)开发了两个主题指南,以评估IDT排序和IDT设置的感知障碍和推动者(医师和护士行为,分别)。我们从安大略省各地招募了血液透析医生和护士的目的样本,并进行了面对面或电话采访。我们使用定向内容分析将转录的话语双重编码到TDF域中,和归纳主题分析来发展主题。
    我们采访了来自安大略省11个血液透析中心的9名医生和9名护士。我们确定了实施IDT的潜在障碍和促进者的七个主题:(1)对临床指南的认识以及IDT如何与当地政策(知识,目标)相适应,(2)使用IDT的好处和动机(对后果的信念;乐观;强化;意图;目标),(3)使IDT与通常的实践和角色(社会/职业角色和身份;行为性质;对能力的信念)保持一致,(4)温度计可用性/准确性和透析机特性(环境背景和资源),(5)对工作量的影响(对后果的信念;对能力的信念),(6)患者舒适度(行为调节;对后果的信念;情绪),和(7)忘记开处方或设置IDT(记忆,注意,决策过程;情感)。
    在随机临床试验中,改变医疗保健专业人员的有效干预行为存在着可对抗的障碍。行为改变框架可以帮助系统地识别这些障碍,以便更好地提供和评估治疗,因此,有可能提高干预措施的保真度,从而提高试验的内部有效性.这些发现将用于优化MyTEMP试验中IDT的交付,并证明该方法如何用于计划其他临床试验中的干预交付。

    Implementing the treatment arm of a clinical trial often requires changes to healthcare practices. Barriers to such changes may undermine the delivery of the treatment making it more likely that the trial will demonstrate no treatment effect. The \'Major outcomes with personalized dialysate temperature\' (MyTEMP) is a cluster-randomised trial to be conducted in 84 haemodialysis centres across Ontario, Canada to investigate whether there is a difference in major outcomes with an individualized dialysis temperature (IDT) of 0.5 °C below a patient\'s body temperature measured at the beginning of each haemodialysis session, compared to a standard dialysis temperature of 36.5 °C. To inform how to deploy the IDT across many haemodialysis centres, we assessed haemodialysis physicians\' and nurses\' perceived barriers and enablers to IDT use.
    We developed two topic guides using the Theoretical Domains Framework (TDF) to assess perceived barriers and enablers to IDT ordering and IDT setting (physician and nurse behaviours, respectively). We recruited a purposive sample of haemodialysis physicians and nurses from across Ontario and conducted in-person or telephone interviews. We used directed content analysis to double-code transcribed utterances into TDF domains, and inductive thematic analysis to develop themes.
    We interviewed nine physicians and nine nurses from 11 Ontario haemodialysis centres. We identified seven themes of potential barriers and facilitators to implementing IDTs: (1) awareness of clinical guidelines and how IDT fits with local policies (knowledge; goals), (2) benefits and motivation to use IDT (beliefs about consequences; optimism; reinforcement; intention; goals), (3) alignment of IDTs with usual practice and roles (social/professional role and identity; nature of the behaviour; beliefs about capabilities), (4) thermometer availability/accuracy and dialysis machine characteristics (environmental context and resources), (5) impact on workload (beliefs about consequences; beliefs about capabilities), (6) patient comfort (behavioural regulation; beliefs about consequences; emotion), and (7) forgetting to prescribe or set IDT (memory, attention, decision making processes; emotion).
    There are anticipatable barriers to changing healthcare professionals\' behaviours to effectively deliver an intervention within a randomised clinical trial. A behaviour change framework can help to systematically identify such barriers to inform better delivery and evaluation of the treatment, therefore potentially increasing the fidelity of the intervention to increase the internal validity of the trial. These findings will be used to optimise the delivery of IDT in the MyTEMP trial and demonstrate how this approach can be used to plan intervention delivery in other clinical trials.
