    背景:全球卫生人力资源(HRH)战略强调需要对HRH进行投资,以满足人口需求并改善优质医疗保健服务的提供。在南非,营养师是公认的提供营养服务的注册专业人员。在本文中,我们使用8步世界卫生组织(WHO)人员配备需求工作量指标(WISN)方法的2个关键步骤(3和4)来确定南非中央和三级公立医院营养师的工作量构成和活动标准.
    方法:所有(9)省级营养管理人员(第一阶段)以及中央和三级公立医院的22位营养师(第二阶段)中的21位参加了在线调查。在第一阶段,省级经理提供了所在省份营养师的工作描述(JD),和JD进行了分析,以确定基线工作负载组件。在第二阶段,营养师参与了多阶段Delphi流程,就工作量构成和活动标准达成共识.共识被认为是70%或更多的共识,而参与者回答的中位数用于获得对活动标准的共识。
    结果:营养师的JD是共识练习的有用基线,因为没有其他合适的源文件。所有三轮Delphi调查的应答率为100%。营养师就92%的拟议工作量组成部分和活动标准达成了共识(共识≥70%)。在删除重复和某些行政活动之后,共15个健康,通过共识活动,产生了15项支持和15项额外的服务活动,这些活动的活动标准一致。
    结论:德尔菲技术是就南非中央和三级公立医院营养师的工作量构成和活动标准达成协议的合适方法。这项研究的结果现在可用于编制工作量组成部分和活动标准的标准化列表,并最终确定中央和三级公立医院护理水平的饮食人员配备需求。
    BACKGROUND: The global Human Resources for Health (HRH) strategy emphasizes the need to invest in HRH to meet population needs and improve the provision of quality health care services. In South Africa, dietitians are recognized as registered professionals who provide nutrition services. In this paper, we used 2 key steps (3 and 4) of the eight step World Health Organization (WHO) Workload Indicators of Staffing Need (WISN) methodology to determine the workload components and activity standards for dietitians at South African central and tertiary public hospitals.
    METHODS: All (9) provincial nutrition managers (phase one) and 21 out of a total 22 head dietitians at central and tertiary public hospitals (phase two) participated in an online survey. In phase one, the provincial managers provided the job descriptions (JDs) of dietitians in their provinces, and the JDs were analyzed to determine the baseline workload components. In phase two, dietitians participated in a multi-stage Delphi process to reach consensus on workload components and activity standards. Consensus was deemed to be agreement of 70% or more, while the median of participants\' responses was used to obtain consensus on the activity standards.
    RESULTS: The JDs of dietitians were a useful baseline for the consensus exercise as there were no other suitable source documents. The response rate was 100% for all three rounds of the Delphi survey. Dietitians reached agreement (consensus ≥ 70%) on 92% of proposed workload components and activity standards. Following the removal of duplicate and certain administrative activities, a total of 15 health, 15 support and 15 additional service activities with aligned activity standards resulted from the consensus exercise.
    CONCLUSIONS: The Delphi technique was a suitable method for reaching agreement on workload components and activity standards for dietitians at South African central and tertiary public hospitals. The findings from this study can now be used to compile a standardized list of workload components and activity standards and ultimately to determine dietetic staffing needs for the central and tertiary public hospital level of care.

    背景:我们评估了自动引文筛选在制定临床实践指南中的适用性。
    方法:我们前瞻性地比较了常规(Rayyan)和半自动(ASReview软件)方法之间的引文筛选效率。我们在文献中搜索了五个临床问题(CQs),以制定《日本脓毒症和脓毒性休克临床实践指南》。记录完成引文筛选所需时间的客观测量。第一轮筛选后,在初步分析中,灵敏度,特异性,正预测值,使用半自动工具作为指标,以常规方法的结果作为标准参考,计算两种程序的总体筛查时间。在次要分析中,使用第二次筛查后纳入研究的最终列表作为标准参考,在两个程序之间比较了相同的参数.
    结果:在第一次筛查后的五个CQ中,最高和最低的灵敏度,特异性,阳性预测值分别为0.241和0.795;0.991和1.000;以及0.482和0.929。在次要分析中,半自动引文筛选的最高敏感性和特异性分别为1.000和0.997.每100项研究的总筛选时间与传统的引文筛选相比,半自动化显著缩短。
    结论:半自动方法的潜在优势(对于最终研究列表而言,筛查时间更短,识别率更高)值得进一步验证。
    背景:本研究已提交给大学医院医学信息网络临床试验注册中心(UMIN-CTR[UMIN000049366])。
    BACKGROUND: We evaluated the applicability of automated citation screening in developing clinical practice guidelines.
    METHODS: We prospectively compared the efficiency of citation screening between the conventional (Rayyan) and semi-automated (ASReview software) methods. We searched the literature for five clinical questions (CQs) in the development of the Japanese Clinical Practice Guidelines for the Management of Sepsis and Septic Shock. Objective measurements of the time required to complete citation screening were recorded. Following the first screening round, in the primary analysis, the sensitivity, specificity, positive predictive value, and overall screening time were calculated for both procedures using the semi-automated tool as index and the results of the conventional method as standard reference. In the secondary analysis, the same parameters were compared between the two procedures using the final list of included studies after the second screening session as standard reference.
    RESULTS: Among the five CQs after the first screening session, the highest and lowest sensitivity, specificity, and positive predictive values were 0.241 and 0.795; 0.991 and 1.000; and 0.482 and 0.929, respectively. In the secondary analysis, the highest sensitivity and specificity in the semi-automated citation screening were 1.000 and 0.997, respectively. The overall screening time per 100 studies was significantly shorter with semi-automated than with conventional citation screening.
    CONCLUSIONS: The potential advantages of the semi-automated method (shorter screening time and higher discriminatory rate for the final list of studies) warrant further validation.

    结果:在系统的文献检索和综述中,初步确定了85个因素。8人专家组会议后,这些减少到38人,其中增加了10个新因素。经过2轮德尔福(106和57名专业人员,分别),17个因素保持不变,12个因素仍有疑问。后者在名义上的小组会议上进行了评估,由13名专业人士组成,他们决定消除5个因素,包括3,并保留3作为怀疑。8人研究小组会议结束后,最终选择了14个潜在因素。它们与居住地有关,患者的健康状况和社会状况,以及在家提供的医疗保健。
    结论:确定的因素可以改善组织并优化HaH专业人员的日常工作。
    OBJECTIVE: To identify and prioritize a list of factors that contribute to the workload of the hospital at home (HaH) professionals.
    METHODS: A qualitative methodology study performed between January and December 2019 in the 10 HAH units of the Basque Country. The data were obtained in 4phases: 1. Systematic literature search and review; 2. Expert group meeting; 3. Consensus method: Delphi technique (2 survey rounds) and nominal group meeting; 4. Meeting of the research team.
    RESULTS: In the systematic literature search and review 85 factors were initially identified. These were reduced to 38 after the 8-person expert group meeting, in which 10 new factors were added. After the 2 Delphi rounds (106 and 57 professionals, respectively), 17 factors were maintained and 12 remained in doubt. The latter were evaluated at the nominal group meeting, consisting of 13 professionals who decided to eliminate 5 factors, include 3, and keep 3 as doubt. After the 8-person research team meeting, 14 potential factors were finally selected. They are related to the place of residence, the health state and social situation of the patients, as well as the health care provided at home.
    CONCLUSIONS: The identified factors could serve for improving the organization and optimize the daily word of the HaH professionals.

    需要进行更大的评估,以确定护士指南依从性中的障碍或促进者。本综述旨在探讨影响护士依从性的外在和内在因素。
    采用融合方法的混合方法系统综述,遵循PRISMA检查表和JBI混合方法审查方法学指南。MEDLINE,Embase,CINAHL进行了系统搜索,寻找2010年至2021年发表的研究,包括定性,定量或混合方法文章。
    纳入了60项研究,并通过将主要发现汇总在两个主要主题上来分析:内在因素和外在因素。内在因素是:a)知识和技能;b)卫生人员的态度;c)对准则的归属感。外在因素是:a)组织和环境因素;b)工作量;c)指南结构;d)患者和护理人员的态度。
    纳入的研究报告缺乏资源,在环境因素中,作为感知的主要障碍。护士,他们在解决直接应用知识和技能以确保患者安全方面处于最前沿,比其他医护人员对这种障碍有更高的认识。审查中出现的潜在促进者是工作场所的积极反馈和加强,无论是团队成员还是领导者。此外,患者和护理人员的积极参与水平可能对护士指南的依从性产生积极影响.准则的实施仍然是一个复杂的过程,因此强烈建议支持卫生政策制定者和护理领导者实施继续教育计划。
    Greater evaluations are needed to identify barriers or facilitators in nurses\' guidelines adherence. The current review aims to explore extrinsic and intrinsic factors impacting nurses\' compliance.
    Mixed-method systematic review with a convergent approach, following the PRISMA checklist and the JBI Mixed Methods Review Methodological Guidance was conducted. MEDLINE, Embase, CINAHL were systematically searched, to find studies published between 2010 and 2021, including qualitative, quantitative or mixed-methods articles.
    Sixty studies were included, and the major findings were analysed by aggregating them in two main themes: intrinsic and extrinsic factors. The intrinsic factors were: a) knowledge and skills; b) attitudes of health personnel; c) sense of belonging towards guidelines. The extrinsic factors were: a) organizational and environmental factors; b) workload; c) guidelines structure; d) patients and caregivers\' attitude.
    The included studies report lack of resources, among environmental factors, as the main barrier perceived. Nurses, who are at the forefront in addressing the direct application of knowledge and skills to ensure patient safety, have a higher perception of this kind of barriers than other healthcare personnel. Potential facilitators emerged in the review are positive feedback and reinforcements at the workplace, either from the members of the team or from the leaders. Moreover, the level of active participation of the patient and caregiver could have a positive impact on nurses\' guidelines adherence. Guidelines implementation remains a complex process, resulting in a strong recommendation to support health policymakers and nursing leaders in implementing continuing education programs.

    工业4.0是用来总结正在进行的第四次工业革命的概念。这正在深刻地改变着世界各地的制造系统和商业模式。协作机器人是工业4.0最有前途的技术之一。人机交互和人机协作对于提高操作员的工作条件和生产性能至关重要。在这方面,这种使能技术带来了新的可能性,但也带来了新的挑战。毫无疑问,当人类和机器人在工业环境中互动时,安全至关重要。然而,人为因素和认知人体工程学(即认知工作量,可用性,信任,接受,压力,挫败感,感知的享受)是至关重要的,即使他们经常被低估或忽视。因此,这项工作涉及人机协作装配系统设计中的认知工效学。根据对科学文献的分析,已经制定了一套设计指南。基于实验室案例研究,通过多个实验对其有效性进行了评估,其中不同的参与者与低有效载荷协作机器人系统进行了交互,以进行制造产品的关节组装。要测试的主要假设是,可以通过根据提出的设计指南操纵系统特征和交互模式来提高操作员的经验和效率。结果证实,通过实施越来越多的指南,参与者通过增强工作站功能和交互条件,改善了对人机交互的认知反应以及组装性能。
    Industry 4.0 is the concept used to summarize the ongoing fourth industrial revolution, which is profoundly changing the manufacturing systems and business models all over the world. Collaborative robotics is one of the most promising technologies of Industry 4.0. Human-robot interaction and human-robot collaboration will be crucial for enhancing the operator\'s work conditions and production performance. In this regard, this enabling technology opens new possibilities but also new challenges. There is no doubt that safety is of primary importance when humans and robots interact in industrial settings. Nevertheless, human factors and cognitive ergonomics (i.e. cognitive workload, usability, trust, acceptance, stress, frustration, perceived enjoyment) are crucial, even if they are often underestimated or ignored. Therefore, this work refers to cognitive ergonomics in the design of human-robot collaborative assembly systems. A set of design guidelines has been developed according to the analysis of the scientific literature. Their effectiveness has been evaluated through multiple experiments based on a laboratory case study where different participants interacted with a low-payload collaborative robotic system for the joint assembly of a manufacturing product. The main assumption to be tested is that it is possible to improve the operator\'s experience and efficiency by manipulating the system features and interaction patterns according to the proposed design guidelines. Results confirmed that participants improved their cognitive response to human-robot interaction as well as the assembly performance with the enhancement of workstation features and interaction conditions by implementing an increasing number of guidelines.

    2011年,美国国家健康与护理卓越研究所(NICE)指南建议常规使用非办公室血压(BP)监测来诊断高血压。预测这些变化可以减少与误诊相关的不必要的治疗成本和工作量。
    评估一般实践中指南变更对高血压相关咨询率的影响。
    在2006年4月1日至2017年3月31日期间,一项针对注册有英国一般实践的成年人的回顾性开放队列研究,为临床实践研究数据链做出了贡献。
    主要结果是面对面的比率,电话,与全科医生或护士进行与高血压相关的家庭访问咨询。年龄和性别标准化率使用中断时间序列分析进行分析。
    在3937191名成年人(中位随访4.2年)中,有12253836名高血压相关咨询。2006年4月,与高血压相关的咨询率为71.0/100人年(95%置信区间[CI]=67.8至74.2),在2011年之前保持不变。2011年引入NICE高血压指南与年度趋势变化有关(趋势变化-每100人年3.60,95%CI=-5.12至-2.09)。咨询率随后在2017年3月降至每100人年59.2(95%CI=56.5至61.8)。这些变化发生在诊断前后,并在考虑所有磋商中的更广泛趋势时坚持。
    高血压相关的工作量在过去十年中有所下降,与指导方针的变化有关。这是由于诊断时工作量的变化,而不是减少误诊。
    In 2011, National Institute for Health and Care Excellence (NICE) guidelines recommended the routine use of out-of-office blood pressure (BP) monitoring for the diagnosis of hypertension. These changes were predicted to reduce unnecessary treatment costs and workload associated with misdiagnosis.
    To assess the impact of guideline change on rates of hypertension-related consultation in general practice.
    A retrospective open cohort study in adults registered with English general practices contributing to the Clinical Practice Research Datalink between 1 April 2006 and 31 March 2017.
    The primary outcome was the rate of face-to-face, telephone, and home visit consultations related to hypertension with a GP or nurse. Age- and sex-standardised rates were analysed using interrupted time-series analysis.
    In 3 937 191 adults (median follow-up 4.2 years) there were 12 253 836 hypertension-related consultations. The rate of hypertension-related consultation was 71.0 per 100 person-years (95% confidence interval [CI] = 67.8 to 74.2) in April 2006, which remained flat before 2011. The introduction of the NICE hypertension guideline in 2011 was associated with a change in yearly trend (change in trend -3.60 per 100 person-years, 95% CI = -5.12 to -2.09). The rate of consultation subsequently decreased to 59.2 per 100 person-years (95% CI = 56.5 to 61.8) in March 2017. These changes occurred around the time of diagnosis, and persisted when accounting for wider trends in all consultations.
    Hypertension-related workload has declined in the last decade, in association with guideline changes. This is due to changes in workload at the time of diagnosis, rather than reductions in misdiagnosis.

    Artificial intelligence (AI) has made impressive progress over the past few years, including many applications in medical imaging. Numerous commercial solutions based on AI techniques are now available for sale, forcing radiology practices to learn how to properly assess these tools. While several guidelines describing good practices for conducting and reporting AI-based research in medicine and radiology have been published, fewer efforts have focused on recommendations addressing the key questions to consider when critically assessing AI solutions before purchase. Commercial AI solutions are typically complicated software products, for the evaluation of which many factors are to be considered. In this work, authors from academia and industry have joined efforts to propose a practical framework that will help stakeholders evaluate commercial AI solutions in radiology (the ECLAIR guidelines) and reach an informed decision. Topics to consider in the evaluation include the relevance of the solution from the point of view of each stakeholder, issues regarding performance and validation, usability and integration, regulatory and legal aspects, and financial and support services. KEY POINTS: • Numerous commercial solutions based on artificial intelligence techniques are now available for sale, and radiology practices have to learn how to properly assess these tools. • We propose a framework focusing on practical points to consider when assessing an AI solution in medical imaging, allowing all stakeholders to conduct relevant discussions with manufacturers and reach an informed decision as to whether to purchase an AI commercial solution for imaging applications. • Topics to consider in the evaluation include the relevance of the solution from the point of view of each stakeholder, issues regarding performance and validation, usability and integration, regulatory and legal aspects, and financial and support services.

    Diagnosis of heart failure with preserved ejection fraction (HFpEF) is associated with certain difficulties since many patients with HFpEF have a slight left ventricular diastolic dysfunction and normal filling pressure at rest. Diagnosis of HFpEF is improved by using diastolic transthoracic stress-echocardiography with dosed exercise (or diastolic stress test), which allows detection of increased filling pressure during the exercise. The present expert consensus explains the requirement for using the diastolic stress test in diagnosing HFpEF from clinical and pathophysiological standpoints; defines indications for the test with a description of its methodological aspects; and addresses issues of using the test in special patient groups.

    Performing systematic reviews is a time-consuming and resource-intensive process.
    We investigated whether a machine learning system could perform systematic reviews more efficiently.
    All systematic reviews and meta-analyses of interventional randomized controlled trials cited in recent clinical guidelines from the American Diabetes Association, American College of Cardiology, American Heart Association (2 guidelines), and American Stroke Association were assessed. After reproducing the primary screening data set according to the published search strategy of each, we extracted correct articles (those actually reviewed) and incorrect articles (those not reviewed) from the data set. These 2 sets of articles were used to train a neural network-based artificial intelligence engine (Concept Encoder, Fronteo Inc). The primary endpoint was work saved over sampling at 95% recall (WSS@95%).
    Among 145 candidate reviews of randomized controlled trials, 8 reviews fulfilled the inclusion criteria. For these 8 reviews, the machine learning system significantly reduced the literature screening workload by at least 6-fold versus that of manual screening based on WSS@95%. When machine learning was initiated using 2 correct articles that were randomly selected by a researcher, a 10-fold reduction in workload was achieved versus that of manual screening based on the WSS@95% value, with high sensitivity for eligible studies. The area under the receiver operating characteristic curve increased dramatically every time the algorithm learned a correct article.
    Concept Encoder achieved a 10-fold reduction of the screening workload for systematic review after learning from 2 randomly selected studies on the target topic. However, few meta-analyses of randomized controlled trials were included. Concept Encoder could facilitate the acquisition of evidence for clinical guidelines.
