    在医疗保健行业内,越来越多的证据表明,员工调查可能会伤害参与该过程的个人,一个组织的文化和服务的交付。
    本文详细介绍了由NHS威尔士组织开发的一项干预措施,该措施旨在通过在整个组织范围内推广“最后手段”方法来减少其员工调查的数量,并引入了“可避免的员工伤害”的概念。制定了一系列相关的改进措施,以支持负责确定是否应启动员工调查的人员的行为改变。
    在13个月的时间里,组织记录显示,干预后调查案件每年减少71%,估计每年可避免3,308个病假日,估计每年可节省738,133英镑(基于直接节省和避免的成本)。这表明该组织已经开始采用“最后手段”的方法来使用员工调查来解决工作场所问题。该计划得到了对负责调试和领导组织员工调查的人员的培训的支持。对参加培训讲习班以支持该方案的人的调查数据进行的分析表明,参与者对讲习班后的员工调查过程的认识有所提高,对可避免的员工伤害的概念也有所了解。
    该计划与健康医疗保健概念一致,正如这项研究说明了其实践和流程如何对员工产生有益的影响,以及潜在的患者。这项研究突出了需要考虑的更广泛的问题,包括:(1)人力资源(HR)的作用,(2)采取多学科的方法,(3)文化与实践,(4)更广泛的HR职业的责任。
    UNASSIGNED: There is growing evidence within the healthcare sector that employee investigations can harm individuals involved in the process, an organization\'s culture and the delivery of its services.
    UNASSIGNED: This paper details an intervention developed by an NHS Wales organization to reduce the number of its employee investigations through an organization-wide focus that promoted a \'last resort\' approach and introduced the concept of \'avoidable employee harm\'. A range of associated improvement initiatives were developed to support behavior change among those responsible for determining whether an employee investigation should be initiated.
    UNASSIGNED: Over a 13-month period, organizational records showed an annual reduction of 71% in investigation cases post-intervention, resulting in an estimated 3,308 sickness days averted annually and total estimated annual savings of £738,133 (based on direct savings and costs averted). This indicates that the organization has started to embrace the \"last resort\" approach to using employee investigations to address work place issues. The programme was supported with training for those responsible for commissioning and leading the organization\'s employee investigations. Analysis of survey data from those who attended training workshops to support the programme indicated that participants showed an increased awareness of the employee investigation process post-workshop and an understanding of the concept of avoidable employee harm.
    UNASSIGNED: The programme is congruent with the Healthy Healthcare concept, as the study illustrates how its practices and processes have a beneficial impact on staff, as well as potentially on patients. This study highlights wider issues for consideration, including the: (1) the role of Human Resources (HR), (2) taking a multi-disciplinary approach, (3) culture and practice, (4) the responsibility of the wider HR profession.

    BACKGROUND: The UK medical education system faces a complex landscape of specialty training choices and heightened competition. The Factors Affecting Specialty Training Preference Among UK Medical Students (FAST) study addresses the need to understand the factors influencing UK medical students\' specialty choices, against a backdrop of increasing challenges in health care workforce planning.
    OBJECTIVE: The primary objectives of the FAST study are to explore UK medical students\' preferred specialties and the factors that influence these choices. Secondary objectives are to evaluate students\' confidence in securing their chosen specialty, to understand how demographic and academic backgrounds affect their decisions, and to examine how specialty preferences and confidence levels vary across different UK medical schools.
    METHODS: A cross-sectional survey design will be used to collect data from UK medical students. The survey, comprising 17 questions, uses Likert scales, multiple-choice formats, and free-text entry to capture nuanced insights into specialty choice factors. The methodology, adapted from the Ascertaining the Career Intentions of UK Medical Students (AIMS) study, incorporates adjustments based on literature review, clinical staff feedback, and pilot group insights. This approach ensures comprehensive and nondirective questioning. Data analysis will include descriptive statistics to establish basic patterns, ANOVA for group comparisons, logistic regression for outcome modeling, and discrete choice models for specialty preference analysis.
    RESULTS: The study was launched nationally on December 4, 2023. Data collection is anticipated to end on March 1, 2024, with data analysis beginning thereafter. The results are expected to be available later in 2024.
    CONCLUSIONS: The FAST study represents an important step in understanding the factors influencing UK medical students\' career pathways. By integrating diverse student perspectives across year groups and medical schools, this study seeks to provide critical insights into the dynamics of specialty, or residency, selection. The findings are anticipated to inform both policy and educational strategies, aiming to align training opportunities with the evolving needs and aspirations of the future medical workforce. Ultimately, the insights gained may guide initiatives to balance specialty distribution, improve career guidance, and improve overall student satisfaction within the National Health Service, contributing to a more stable and effective health care system.

    异染性脑白质营养不良(MLD)是一种致命的遗传性溶酶体贮积病,可通过新生儿血斑筛查检测到。筛选试验的可行性和筛选MLD的临床原理先前已被证明,因此,本研究的目的是确定在英国常规新生儿筛查计划中增加MLD筛查是否具有成本效益地使用国家卫生服务(NHS)资源.基于每个MLD亚型的决策树框架,从NHS和个人社会服务的角度进行了健康经济分析,使用从先前提出的分区生存和马尔可夫经济模型得出的长期结果。流行病学相关参数的建模输入,测试特性,筛查和治疗费用是基于来自英国三大专业MLD医院的数据,结构化的专家意见和已发表的文献。寿命成本和质量调整寿命年(QALYs)以1.5%的折扣来考虑时间偏好。使用敏感性分析探索与参数输入相关的不确定性。这项健康经济分析表明,使用符合疾病严重程度的支付意愿阈值,对MLD进行新生儿筛查是对NHS资源的一种具有成本效益的使用;并支持将MLD纳入英国的常规新生儿筛查计划。
    Metachromatic leukodystrophy (MLD) is a fatal inherited lysosomal storage disease that can be detected through newborn bloodspot screening. The feasibility of the screening assay and the clinical rationale for screening for MLD have been previously demonstrated, so the aim of this study is to determine whether the addition of screening for MLD to the routine newborn screening program in the UK is a cost-effective use of National Health Service (NHS) resources. A health economic analysis from the perspective of the NHS and Personal Social Services was developed based on a decision-tree framework for each MLD subtype using long-term outcomes derived from a previously presented partitioned survival and Markov economic model. Modelling inputs for parameters related to epidemiology, test characteristics, screening and treatment costs were based on data from three major UK specialist MLD hospitals, structured expert opinion and published literature. Lifetime costs and quality-adjusted life years (QALYs) were discounted at 1.5% to account for time preference. Uncertainty associated with the parameter inputs was explored using sensitivity analyses. This health economic analysis demonstrates that newborn screening for MLD is a cost-effective use of NHS resources using a willingness-to-pay threshold appropriate to the severity of the disease; and supports the inclusion of MLD into the routine newborn screening programme in the UK.

    背景:随着改善阿尔茨海默病(AD)的治疗方法的出现,有人担心,即使是高收入国家也缺乏及时准确识别合格患者的诊断能力。
    目的:我们分析了NHS英格兰在AD专家的能力上需要投资多少,使用PET扫描或CSF测试和MRI扫描进行生物标志物测试,以达到G7平均水平,并评估对诊断过程中等待时间的影响。
    方法:成本和容量数据的案头研究和专家访谈。马尔可夫模型来估计等待时间。
    方法:NHS英格兰。
    方法:AD专家,G7国家的人均PET和MRI扫描仪,以及不同投资情景下英国的等待时间。
    结果:在七国集团国家中,英国的PET和MRI扫描仪数量最少,人均AD专家数量排名第二。需要在十年内投资140亿英镑才能达到G7的平均水平,其中31%,22%,10%,37%将用于内存评估服务的容量,PET扫描,CSF分析,和核磁共振扫描,分别。这项投资将使2023年至2032年间的平均等待时间减少约87%。
    结论:英国NHS在AD诊断能力方面存在很大差距。如果没有大量投资,英格兰的AD患者将经历大量的等待时间和可避免的疾病进展。
    BACKGROUND: As disease-modifying Alzheimer\'s (AD) treatments are becoming available, concerns have been raised that even high-income countries lack the diagnostic capacity to accurately identify eligible patients in a timely manner.
    OBJECTIVE: We analyze how much NHS England would have to invest in capacity for AD specialists, biomarker testing with PET scans or CSF testing and MRI scans to reach G7 average levels and estimate the effect on wait times in the diagnostic process.
    METHODS: Desk research and expert interviews for cost and capacity data. Markov model to estimate wait times.
    METHODS: NHS England.
    METHODS: AD specialists, and PET and MRI scanners per capita in G7 countries and wait times in England under different investment scenarios.
    RESULTS: England has the lowest number of PET and MRI scanners and the second-lowest of AD specialists per capita among the G7 countries. An investment of GBP 14 billion over ten years would be needed to reach G7 average levels, of which 31%, 22%, 10%, 37% would be devoted to capacity for memory assessment services, PET scanning, CSF analysis, and MRI scanning, respectively. This investment would reduce estimated average wait times by around 87% between 2023 and 2032.
    CONCLUSIONS: The NHS England has large gaps in diagnostic capacity for AD. Without substantial investments, AD patients in England would experience substantial wait times and avoidable disease progression.

    化疗引起的恶心和呕吐(CINV)是癌症治疗的一种使人衰弱的副作用,影响许多患者。大麻素激动剂,例如纳比酮和Δ9-四氢大麻酚(THC),大麻的主要精神活性成分,已显示出作为止吐药的功效。这里,我们报道了迈克尔·罗伯茨(MR)的病例,我们认为,他是英国国家卫生服务(NHS)为管理CINV的药用大麻花费用报销的第一位英国患者。医疗数据来自NHS记录和个人资助请求(IFR)表格。使用经过验证的问卷收集患者报告的结果指标(PROM),作为开始处方药用大麻的专业私人诊所的护理标准的一部分。患者表现为直肠乙状结肠腺癌伴肺转移。他收到了FOLFIRI(亚叶酸,氟尿嘧啶,和伊立替康)化疗,并接受了紧急哈特曼手术,随后进行了二线FOLFOX(亚叶酸,氟尿嘧啶,和奥沙利铂)化疗和肺消融。MR报告与初始FOLFIRI治疗相关的严重恶心和呕吐。止吐药甲氧氯普胺和阿瑞吡坦显示出适度的疗效。止吐药昂丹司琼,左甲丙嗪,和纳比隆与不能容忍的副作用有关。吸入以THC为主的大麻花与标准药物改善CINV相关,焦虑,睡眠质量,食欲,整体情绪,和生活质量。我们的结果增加了现有证据,表明药用大麻花可能在癌症姑息治疗与标准治疗肿瘤治疗相结合中提供有价值的支持。在这种情况下,成功的个人资助请求证明了其他患者获得这些治疗的途径。倡导在国家医疗保健服务中更广泛地认识和整合大麻基医药产品。
    Chemotherapy-induced nausea and vomiting (CINV) is a debilitating side effect of cancer treatment, affecting many patients. Cannabinoid agonists, such as nabilone and Δ9-tetrahydrocannabinol (THC), the main psychoactive component of Cannabis sativa L., have shown efficacy as antiemetics. Here, we report the case of Michael Roberts (MR), who we believe is the first British patient reimbursed by the National Health Service (NHS) England for the cost of medicinal cannabis flowers to manage CINV. Medical data were obtained from NHS records and individual funding request (IFR) forms. Patient-reported outcome measures (PROMs) were collected using validated questionnaires as part of the standard of care at the specialized private clinics where the prescription of medicinal cannabis was initiated. The patient presented with rectosigmoid adenocarcinoma with lung metastases. He received FOLFIRI (folinic acid, fluorouracil, and irinotecan) chemotherapy and underwent an emergency Hartmann\'s procedure with subsequent second-line FOLFOX (folinic acid, fluorouracil, and oxaliplatin) chemotherapy and lung ablation. MR reported severe nausea and vomiting associated with the initial FOLFIRI treatment. Antiemetics metoclopramide and aprepitant demonstrated moderated efficacy. Antiemetics ondansetron, levomepromazine, and nabilone were associated with intolerable side effects. Inhalation of THC-predominant cannabis flowers in association with standard medication improved CINV, anxiety, sleep quality, appetite, overall mood, and quality of life. Our results add to the available evidence suggesting that medicinal cannabis flowers may offer valuable support in cancer palliative care integrated with standard-of-care oncology treatment. The successful individual funding request in this case demonstrates a pathway for other patients to gain access to these treatments, advocating for broader awareness and integration of cannabis-based medicinal products in national healthcare services.

    本文探讨了“患者安全的时刻”-2000年左右的时期,当时患者安全成为英国国家卫生服务(NHS)的主要政策关注,和其他医疗保健系统。虽然医疗造成的伤害(医源性损伤)早已得到临床医生和科学家的认可,从2000年开始,NHS中出现了一种新的系统的患者安全语言,促进了对患者伤害的新型管理和监管方法.这种语言反映了国家在调节医疗保健方面的作用越来越大,以及医疗自主权的侵蚀和新的官僚管理形式的兴起。承认一个跨国公司,对患者安全的政策兴趣上升背后的知识背景——例如,工业安全科学见解的应用-本文考察了国内文化因素所起的作用,如医疗过失诉讼和医疗丑闻,帮助定义英国的新语言。
    This article explores the \'the moment of patient safety\'-the period around 2000 when patient safety became a key policy concern of the British National Health Service (NHS), and other healthcare systems. While harm caused by medical care (iatrogenic injury) had long been acknowledged by clinicians and scientists, from 2000 a new systemic language of patient safety emerged in the NHS that promoted novel managerial and regulatory approaches to patient harm. This language reflected the state\'s increasing role in regulating healthcare, as well as the erosion of medical autonomy and the rise of new forms of bureaucratic management. Acknowledging a transnational, intellectual context behind the rise of policy interest in patient safety-for example, the application of insights from the industrial safety sciences-this article examines the role played by domestic cultural factors, such as medical negligence litigation and healthcare scandals, in helping to define the new language in Britain.

    背景:在没有增加资金或人员配备的情况下,大多数精神卫生保健提供者面临着对心理治疗需求增加的挑战。为了克服这种供需不平衡,护理提供者必须提高服务提供的效率。
    目的:在本研究中,我们研究了支持人工智能(AI)的数字解决方案是否可以帮助精神卫生保健从业者更有效地利用他们的时间,从而减轻服务压力,改善患者预后。
    方法:在本研究中,我们专注于使用AI解决方案(LimbicAccess)来支持英国国家卫生服务机构的初始患者转诊和临床评估.数据来自英格兰的9家谈话疗法服务机构,包括64,862名患者。
    结果:我们表明,使用此AI解决方案可以通过减少临床医生在心理健康评估上花费的时间来提高临床效率。此外,我们在几个关键指标中发现使用AI解决方案的患者的预后有所改善,例如减少等待时间,降低辍学率,改善对适当治疗途径的分配,and,最重要的是,提高回收率。在调查AI解决方案实现这些改进的机制时,我们发现,在临床评估之前提供临床相关信息对于这些观察到的效应至关重要.
    结论:我们的结果强调了使用AI解决方案来支持精神卫生劳动力的效用,进一步强调AI解决方案在提高医疗服务效率和改善患者临床结局方面的潜力.
    BACKGROUND: Most mental health care providers face the challenge of increased demand for psychotherapy in the absence of increased funding or staffing. To overcome this supply-demand imbalance, care providers must increase the efficiency of service delivery.
    OBJECTIVE: In this study, we examined whether artificial intelligence (AI)-enabled digital solutions can help mental health care practitioners to use their time more efficiently, and thus reduce strain on services and improve patient outcomes.
    METHODS: In this study, we focused on the use of an AI solution (Limbic Access) to support initial patient referral and clinical assessment within the UK\'s National Health Service. Data were collected from 9 Talking Therapies services across England, comprising 64,862 patients.
    RESULTS: We showed that the use of this AI solution improves clinical efficiency by reducing the time clinicians spend on mental health assessments. Furthermore, we found improved outcomes for patients using the AI solution in several key metrics, such as reduced wait times, reduced dropout rates, improved allocation to appropriate treatment pathways, and, most importantly, improved recovery rates. When investigating the mechanism by which the AI solution achieved these improvements, we found that the provision of clinically relevant information ahead of clinical assessment was critical for these observed effects.
    CONCLUSIONS: Our results emphasize the utility of using AI solutions to support the mental health workforce, further highlighting the potential of AI solutions to increase the efficiency of care delivery and improve clinical outcomes for patients.

    海外护士对英国(英国)并不陌生,牧师关怀的概念也不是。国际护士的巨大贡献是如此明显,以至于人们普遍认为这些护士将有一个强有力的关于牧养的文献基础。然而,情况恰恰相反。田园支持对于在英国以外招募的护士成功适应和融入NHS工作至关重要。为了提供全面的适合用途的支持,护士的观点很重要。
    本范围审查旨在确定对英国受过国际教育的护士的牧养支持的已知情况。
    使用范围审查方法来审查有关牧区支持的文献。
    现有文献提供了当前实践的证据,挑战,以及成功的牧区支持的结果标准。它还提供了有关早期牧师支持如何加强护士或取消他们的技能的证据。最后,它显示了海外护士获得的支持存在显着差异。
    虽然已经探索了先前适应计划的护士经验,关于当前牧区护理做法的证据大多在政策指导方针中找到,培训师报告,和意见片。自2014年NMC能力测试开始以来,牧养接受者的声音尚未被听到。这项范围界定审查表明,对牧区护理实践的理解存在差异。因此,在这个问题上,应该探讨黑非洲护士等特定群体的观点.
    UNASSIGNED: Overseas nurses are not new to the United Kingdom (UK), and neither is the concept of pastoral care. The immense contributions of international nurses are so obvious that it would be commonly assumed that there will be a strong literature base on pastoral care for these nurses. However, the opposite is very much the case. Pastoral support is crucial to the successful adaptation and integration of nurses who are recruited outside the United Kingdom to work within the NHS. To offer comprehensive fit-for-purpose support, the perspective of the nurses is important.
    UNASSIGNED: This scoping review aims to identify what is known about pastoral support for internationally educated nurses in the UK.
    UNASSIGNED: A scoping review method was used to review literature on pastoral support.
    UNASSIGNED: Existing literature provided evidence on current practices, the challenges, and outcome criteria for successful pastoral support. It also provided evidence on how early pastoral support can fortify the nurses or deskill them. Finally, it revealed significant disparities in the support received by overseas nurses.
    UNASSIGNED: While the nurses\' experience of the previous adaptation programme has been explored, evidence on the current pastoral care practices is mostly found in policy guidelines, trainers\' reports, and opinion pieces. Since the inception of the NMC test of competence in 2014, the voice of the recipients of pastoral care is yet to be heard. This scoping review suggests that there is a difference in understanding of pastoral care practices. Therefore, the perspectives of specific groups such as Black African nurses should be explored on this issue.

    结论:这项研究揭示了英国医学院学生职业情绪的差异,强调需要注意影响这些趋势的因素。有相当比例的学生打算在毕业后的2年内退出NHS,机构之间有很大的差异。学生的意图可能受到各种因素的影响,包括课程重点和招聘实践。必须在医学院内重新评估这些方面,同时考虑到更广泛的国情,提高学生对NHS职业的看法。未来的研究应针对这些差异的根本原因,以促进职业满意度和保留率的提高。
    OBJECTIVE: To investigate differences in students\' career intentions between UK medical schools.
    METHODS: Cross-sectional, mixed-methods online survey.
    METHODS: The primary study included all 44 UK medical schools, with this analysis comprising 42 medical schools.
    METHODS: Ten thousand four hundred eighty-six UK medical students.
    METHODS: Career intentions of medical students, focusing on differences between medical schools. Secondary outcomes included variation in medical students\' satisfaction with a prospective career in the NHS, by medical school.
    RESULTS: 2.89% of students intended to leave medicine altogether, with Cambridge Medical School having the highest proportion of such respondents. 32.35% of respondents planned to emigrate for practice, with Ulster medical students being the most likely. Of those intending to emigrate, the University of Central Lancashire saw the highest proportion stating no intentions to return. Cardiff Medical School had the greatest percentage of students intending to assume non-training clinical posts after completing FY2. 35.23% of participating medical students intended to leave the NHS within 2 years of graduating, with Brighton and Sussex holding the highest proportion of these respondents. Only 17.26% were satisfied with the prospect of working in the NHS, with considerable variation nationally; Barts and the London medical students had the highest rates of dissatisfaction.
    CONCLUSIONS: This study reveals variability in students\' career sentiment across UK medical schools, emphasising the need for attention to factors influencing these trends. A concerning proportion of students intend to exit the NHS within 2 years of graduating, with substantial variation between institutions. Students\' intentions may be shaped by various factors, including curriculum focus and recruitment practices. It is imperative to re-evaluate these aspects within medical schools, whilst considering the wider national context, to improve student perceptions towards an NHS career. Future research should target underlying causes for these disparities to facilitate improvements to career satisfaction and retention.

    交联过程改善了生物聚合物基复合材料的物理化学性能,使它们对生物医学应用有价值。EDC/NHS交联的胶原蛋白材料在组织工程应用中具有巨大的潜力,由于其增强的性能和生物相容性。样品的化学交联可以通过几种方式进行,这是至关重要的,对所获得材料的最终性能有直接影响。在这项研究中,研究了交联条件对使用EDC和NHS的胶原膜性能的影响。研究包括FTIR光谱,AFM,溶胀和降解试验,机械测试和接触角测量。对制备的胶原膜的评估表明,交联剂和交联条件都会影响膜的性能。在样品的红外光谱中观察到明显的变化,将EDC直接添加到鱼胶原蛋白溶液中。相同的样品显示最低的杨氏模量,拉伸强度和断裂力参数和最高断裂伸长率。所有样品在PBS溶液中浸泡两小时后达到最大溶胀度;然而,浸渍交联的样品表现出明显较低的溶胀度,并且具有很高的耐久性。用EDC交联的胶原膜的粗糙度最高,而与添加NHS的EDC交联的样品观察到最低。交联剂增加了胶原膜的表面粗糙度,除了通过添加EDC和NHS混合物而改性的样品。所有膜的特征在于亲水特性。薄膜改性导致其亲水性和润湿性降低。我们的研究可以比较拟议的EDC/NHS交联条件及其对鱼胶原蛋白薄膜的物理化学性质的影响。EDC和NHS是用于生物医学应用中的鱼胶原蛋白改性的有前途的交联剂。
    The process of crosslinking improves the physicochemical properties of biopolymer-based composites, making them valuable for biomedical applications. EDC/NHS-crosslinked collagen materials have a significant potential for tissue engineering applications, due to their enhanced properties and biocompatibility. Chemical crosslinking of samples can be carried out in several ways, which is crucial and has a direct effect on the final properties of the obtained material. In this study, the effect of crosslinking conditions on the properties of collagen films using EDC and NHS was investigated. Studies included FTIR spectroscopy, AFM, swelling and degradation tests, mechanical testing and contact angle measurements. Evaluation of prepared collagen films indicated that both crosslinking agents and crosslinking conditions influenced film properties. Notable alternations were observed in the infrared spectrum of the sample, to which EDC was added directly to the fish collagen solution. The same sample indicated the lowest Young modulus, tensile strength and breaking force parameters and the highest elongation at break. All samples reached the maximum swelling degree two hours after immersion in PBS solution; however, the immersion-crosslinked samples exhibited a significantly lower degree of swelling and were highly durable. The highest roughness was observed for the collagen film crosslinked with EDC, whereas the lowest was observed for the specimen crosslinked with EDC with NHS addition. The crosslinking agents increased the surface roughness of the collagen film, except for the sample modified with the addition of EDC and NHS mixture. All films were characterized by hydrophilic character. The films\' modification resulted in a decrease in their hydrophilicity and wettability. Our research allows for a comparison of proposed EDC/NHS crosslinking conditions and their influence on the physicochemical properties of fish collagen thin films. EDC and NHS are promising crosslinking agents for the modification of fish collagen used in biomedical applications.
