    在台湾的国民健康保险(NHI)制度下,对于所有医疗保健提供者来说,向国家健康保险管理局(NHIA)准确提交医疗费用索赔是至关重要的,以避免不正确的扣除。随着医疗政策的变化和医院管理策略的调整,索赔规则的复杂性导致医院在医疗费用索赔程序上花费大量人力和时间。因此,本研究利用精益六西格玛DMAIC(定义,Measure,分析,改善,控制)的管理方法,以识别过程中的浪费和非增值步骤。同时,它引入了机器人过程自动化(RPA)工具来取代手工操作。实施后,该研究有效地减少了380分钟的过程时间和提高过程循环效率(PCE)从69.07到95.54%。这项研究验证了医疗机构精益数字化转型的真实案例。它使人力资源能够分配给更有价值和创造性的任务,同时协助医院提供更全面和以患者为中心的服务。
    Under Taiwan\'s National Health Insurance (NHI) system, it\'s crucial for all healthcare providers to accurately submit medical expense claims to the National Health Insurance Administration (NHIA) to avoid incorrect deductions. With changes in healthcare policies and adjustments in hospital management strategies, the complexity of claiming rules has resulted in hospitals expending significant manpower and time on the medical expense claims process. Therefore, this study utilizes the Lean Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) management approach to identify wasteful and non-value-added steps in the process. Simultaneously, it introduces Robotic Process Automation (RPA) tools to replace manual operations. After implementation, the study effectively reduces the process time by 380 min and enhances Process Cycle Efficiency (PCE) from 69.07 to 95.54%. This research validates a real-world case of Lean digital transformation in healthcare institutions. It enables human resources to be allocated to more valuable and creative tasks while assisting hospitals in providing more comprehensive and patient-centric services.

    背景:精益,特别是价值流图越来越多地用于医院优化流程。这种方法,起源于汽车行业,使参与该过程的所有员工都能使其对客户更加友好。尽管精益项目取得了广泛的成功,他们在某些情况下失败了。本研究调查了有助于成功实施价值流映射的环境因素和机制。
    方法:将价值流图应用于四个乳腺癌中心的出院过程。混合方法分两步使用。首先,为了验证成功实施,定义为时间优化,在三个时间点进行时间测量,并使用ANOVA进行分析.第二,对环境因素的分析与基于规范化过程理论的机制的定性内容分析相结合,使用常规数据,会议协议,字段注释,和采访笔录作为数据源。
    结果:在四个乳腺癌中心之一,前导和等待时间大大减少;在其他方面,这些减少没有发生。失败/成功不能用医院的规模来解释,案件数量或人员配备水平。可变的项目团队组成是显而易见的,尤其是领导参与。
    结论:进行了比较分析,以确定导致成功的因素。这些因素是:与该进程相关的所有领导人的参与,在出院过程中,包括医疗和护理领导;将项目团队的变化传播给同事,包括讨论它的感觉和可能性;在定期的工作团队会议中共同反映实施过程。
    结论:这些结果证实了领导在实施项目中的重要作用。领导支持启用了所发现的机制。来自管理研究和实施科学的理论方法的结合确定了解释,应在实施科学中更频繁地应用。
    BACKGROUND: Lean, especially Value Stream Mapping is increasingly used in hospitals to optimize processes. This method, which originated in the automotive industry, enables all staff involved in the process to make it more customer-friendly. Despite the widely reported success of Lean projects, they have failed in some cases. This study investigated the contextual factors and mechanisms that contribute to a successful implementation of Value Stream Mapping.
    METHODS: Value Stream Mapping was applied to the discharge process in four breast cancer centers. A mixed-method approach was used in two steps. First, to verify the successful implementation, defined as time optimization, time measurement was conducted at three points in time and analyzed using an ANOVA. Second, an analysis of contextual factors was combined with a qualitative content analysis of mechanisms based on normalization process theory, using routine data, meeting protocols, field notes, and interview transcripts as data source.
    RESULTS: At one of the four breast cancer centers, lead- and waiting time were significantly reduced; at the others, these reductions did not occur. Failure/success cannot be explained by the size of the hospital, the number of cases or staffing levels. The variable project team composition is evident, especially leadership involvement.
    CONCLUSIONS: A comparative analysis was conducted to identify the factors that led to success. These factors were: participation of all leaders relevant to the process, in the case of the discharge process including medical and nursing leaders; dissemination of the changes from the project team to colleagues including its sense and possibility to discuss it; joint reflection of the implementation process in regular work team meetings.
    CONCLUSIONS: These results confirm the important role of leadership in implementation projects. Leadership support enabled the mechanisms found. The used combination of theoretical approaches from management research and implementation science determined the interpretation and should be applied more often in implementation science.

    医疗保健的变化往往是基于项目的,整个系统的变化,承认社会技术因素的相互联系,不是规范。本文试图解决特刊提出的整个系统变更问题,并汇集了该特刊中提出的其他研究。采用了案例研究方法,以了解整个系统的部署变化在急性医院环境中,沿着社会技术系统框架的四个维度:文化,系统功能,行动,和理智。案例研究证明了整个系统改进的证据。变革的方法是由员工和管理层共同设计的,涉及所有专业和资历级别的员工的项目相互联系,并与组织的战略目标联系在一起,从第一代项目中吸取的经验教训已经传递到第二代和第三代流程改进。社会技术系统框架用于回顾性评估系统变化,但也可以前瞻性地用于帮助医疗机构开发整个系统改进的方法。
    Changes in healthcare tend to be project-based with whole system change, which acknowledges the interconnectedness of socio-technical factors, not the norm. This paper attempts to address the question of whole system change posed by the special issue and brings together other research presented in this special issue. A case study approach was adopted to understand the deployment of a whole system change in the acute hospital setting along four dimensions of a socio-technical systems framework: culture, system functioning, action, and sense-making. The case study demonstrates evidence of whole system improvement. The approach to change was co-designed by staff and management, projects involving staff from all specialities and levels of seniority were linked to each other and to the strategic objectives of the organisation, and learnings from first-generation projects have been passed to second and third-generation process improvements. The socio-technical systems framework was used retrospectively to assess the system change but could also be used prospectively to help healthcare organisations develop approaches to whole system improvement.

    医护人员必须进行强制性培训计划,以确保他们保持关键的临床能力。这项研究是在爱尔兰的一家私立医院进行的,在那里,访问强制性培训的过程被发现是高度复杂和非用户友好的,导致错过培训机会,特定的培训许可证到期,以及未充分利用的培训时段,导致培训者和受训者都浪费了时间。进行了一项试点研究,以审查获得强制性培训的过程,重点是基本生命支持(BLS)的强制性培训计划。之所以选择这是因为它在患者复苏中的重要性以及在医院中获得国际联合委员会(JCI)认证的要求。采用精益六西格玛(LSS)方法进行基于团队的干预设计,以重新设计预订流程,调度,并提供BLS培训,从而获得员工个人BLS认证,为期两年。BLS培训计划的重新设计产生了一种新的混合交付方法,试点项目的启动导致BLS课程数量增加了50%,员工节省了154小时30分钟的时间,BLS讲师节省了48小时14分钟的时间。BLS流程访问试点的成功已成为重新设计其他强制性教育计划的平台,并将对具有强制性培训要求的医院感兴趣,这些医院已经面临医疗保健挑战和对员工时间的要求。
    Healthcare staff are required to undertake mandatory training programs to ensure they maintain key clinical competencies. This study was conducted in a private hospital in Ireland, where the processes for accessing mandatory training were found to be highly complex and non-user friendly, resulting in missed training opportunities, specific training license expiration, and underutilized training slots which resulted in lost time for both the trainers and trainees. A pilot study was undertaken to review the process for accessing mandatory training with a focus on the mandatory training program of Basic Life Support (BLS). This was chosen due to its importance in patient resuscitation and its requirement in the hospital achieving Joint Commission International (JCI) accreditation. A pre- and post-team-based intervention design was used with Lean Six Sigma (LSS) methodology employed to redesign the process of booking, scheduling, and delivery of BLS training leading to staff individual BLS certification for a period of two years. The redesign of the BLS training program resulted in a new blended delivery method, and the initiation of a pilot project led to a 50% increase in the volume of BLS classes and a time saving of 154 h 30 min for staff and 48 h 14 min for BLS instructors. The success of the BLS process access pilot has functioned as a platform for the redesign of other mandatory education programs and will be of interest to hospitals with mandatory training requirements that are already facing healthcare challenges and demands on staff time.

    目的利用精益六西格玛(LSS)和失效模型与效应分析(FMEA)预防中国教学医院的分配错误。
    收集了医院药剂师向国际合理用药网络中国核心集团报告的用药错误(MEs)。按照LSS方法,数据分析是根据定义构建的,measure,分析,改进,和控制(DMAIC)阶段,和典型的LSS工具(帕累托图,头脑风暴会议)用于确定导致分配错误的风险因素。FMEA用于生成ME事件的风险优先级编号(RPN),通过定量分析失败的影响,确定了针对错误预防策略的关键药物。最后,实施预防MES的纠正措施并监测疗效.
    在实施该计划之前,从第1年到第6年,共报告了603例配药错误,平均发生率为每10000份药物订单0.33例,这些年之间没有发现差异(P=.9424)。位置也没有区别,错误类型,促成因素,考虑了原因分类。然后我们确定了分配错误背后的真正原因,共有67种药物针对特定的错误预防策略.干预一年后,在以下方面取得了进展:与前几年相比,分配错误的发生率显着下降(0.19,P=.007)。同时,门诊药房配药差错发生率(0.04,P=.0008),初级药剂师(0.15,P=0.0258),LASA药物(0.06,P=.0319),以及基于记忆的错误显着减少(0.03,P=.0191)。
    LSS和FMEA工具的组合可以成为帮助减少药房分配中的ME的有效方法。
    To utilize lean six sigma (LSS) and failure model and effect analysis (FMEA) to prevent dispensing errors in a Chinese teaching hospital.
    Medication errors (MEs) reported to the China Core Group of the international network for the rational use of drugs (INRUD) by pharmacists at the hospital were collected. Following LSS methodology, the data analysis was structured according to define, measure, analyse, improve, and control (DMAIC) phases, and typical LSS tools (Pareto diagrams, brainstorming sessions) were used to determine the risk factors leading to dispensing errors. FMEA was applied to generate the risk priority numbers (RPNs) of MEs events, and key medications targeted for error prevention strategies were identified through quantitative analysis of the impacts of failure. Finally, corrective measures to prevent MEs were implemented and monitored for efficacy.
    Before the implementation of this programme, a total of 603 cases of dispensing errors were reported from the Year 1 to Year 6, reaching an average rate of incidence of 0.33 cases per 10 000 medication orders delivered, and no difference was found between these years (P = .9424). There was also no difference as location, error type, contributing factors, cause classification were considered. We then determined the real cause behind dispensing errors, and a total of 67 medications were targeted for specific error prevention strategies. One year after intervention, progress had been achieved in the following aspects: the incidence rate of dispensing errors was significantly decreased compared with the previous years (0.19, P = .007). Simultaneously, the incidence rate of dispensing errors occurred in outpatient pharmacy (0.04, P = .0008), with junior pharmacists (0.15, P = .0258), with LASA medications (0.06, P = .0319), as well as with memory-based errors were significantly decreased (0.03, P = .0191).
    The combination of LSS and the FMEA tool can be an efficient approach for helping reduce MEs in pharmacy dispensing.

    背景:急诊科(ED)的老年人处于功能下降的高风险中,无法识别的谵妄,falls,和药物相互作用。ED中由多学科团队进行的整体评估降低了这些不良后果并减少了入院率。但在急诊就诊期间纳入此类护理有许多障碍。
    方法:这是一项混合的II型有效性实施研究,使用三级护理学术ED和ED观察单元(ObsUnit)的前/后队列设计(n=380)。干预是一个两步方案(步骤1)ED护士使用谵妄分类筛选筛选≥65岁的老年患者,4阶段平衡测试,和识别老年人风险评分。通过此次筛查确定有老年需求但不符合入院标准的患者(第2步)将被安置在Obs单位,由医院的老年咨询小组进行多学科老年评估,物理治疗师,职业治疗师,药剂师,和/或案例经理。并非所有患者都可能需要多学科老年评估的所有要素。实施研究综合框架:护理过渡框架用于确定实施障碍。精益六西格玛过程将用于克服这些确定的障碍,目标是实现>80%的老年筛查率。将报告实施成功和相关因素。对于有效性目标,ED访视后90天(n=150pre和230post),在Obs单元中接受治疗的≥65岁成年人的前/后队列。主要结果是预防功能下降。次要结果包括与健康相关的生活质量,发现了新的老年综合征,提供新服务,和Obs单位指标,如住院时间和录取率。
    结论:在ED设置中实施综合多学科老年评估的方案有可能通过在从ED出院之前识别和解决老年问题和需求来改善患者的功能状态。使用经过验证的框架和实施策略将增加我们对如何在急性护理环境中提高老年人ED护理质量的理解。
    背景:ClinicalTrials.gov标识符,NCT04068311,2019年8月28日注册。
    BACKGROUND: Older adults in the emergency department (ED) are at high risk for functional decline, unrecognized delirium, falls, and medication interactions. Holistic assessment by a multidisciplinary team in the ED decreases these adverse outcomes and decreases admissions, but there are many barriers to incorporating this type of care during the ED visit.
    METHODS: This is a hybrid type II effectiveness-implementation study using a pre-/post-cohort design (n = 380) at a tertiary care academic ED with an ED observation unit (Obs Unit). The intervention is a two-step protocol of (step 1) ED nurses screening adult patients ≥ 65 years old for geriatric needs using the Delirium Triage Screen, 4-Stage Balance Test, and the Identifying Seniors at Risk score. Patients who have geriatric needs identified by this screening but who do not meet hospital admission criteria will (step 2) be placed in the Obs Unit for multidisciplinary geriatric assessment by the hospital\'s geriatric consultation team, physical therapists, occupational therapists, pharmacists, and/or case managers. Not all patients may require all elements of the multidisciplinary geriatric assessment. The Consolidated Framework for Implementation Research: Care Transitions Framework was used to identify barriers to implementation. Lean Six Sigma processes will be used to overcome these identified barriers with the goal of achieving geriatric screening rates of > 80%. Implementation success and associated factors will be reported. For the effectiveness aim, pre-/post-cohorts of adults ≥ 65 years old cared for in the Obs Unit will be followed for 90 days post-ED visit (n = 150 pre and 230 post). The primary outcome is the prevention of functional decline. Secondary outcomes include health-related quality of life, new geriatric syndromes identified, new services provided, and Obs Unit metrics such as length of stay and admission rates.
    CONCLUSIONS: A protocol for implementing integrated multidisciplinary geriatric assessment into the ED setting has the potential to improve patient functional status by identifying and addressing geriatric issues and needs prior to discharge from the ED. Using validated frameworks and implementation strategies will increase our understanding of how to improve the quality of ED care for older adults in the acute care setting.

    OBJECTIVE: Hospital pharmacists are involved in clinical trials for the management of experimental drugs. In our hospital, the pharmacy is in charge of approximately 120 clinical trials and this activity is sub-divided between three sectors. The fragmentation of this activity generates difficulties in terms of heterogeneity of practices, redundancy of activities, and difficulties of communication with stakeholders outside the pharmacy due to the multiplicity of pharmaceutical interlocutors. The aims of this work were to improve and harmonize practices, and to reorganize and globalize the activities carried out in this sector.
    METHODS: A Lean management approach was employed. The process was mapped and then a double analysis was conducted. On the one hand, wastes and irritating were identified collaboratively, at project group meetings. On the other hand, a reorganization model was proposed.
    RESULTS: A diagnosis with 38 points to improve was drawn. The reorganization applied to human resources, by reducing the number of actors involved in a rational way, and secondly, tasks were revised and harmonized.
    CONCLUSIONS: The use of a lean methodology allowed us to perform successfully our reorganization. This approach led to continuous improvement in a collaborative manner in this sector.

    Medication errors are a significant cause of injury in Norwegian hospitals. The purpose of this study is to explore how Lean Six Sigma (LSS) has been used in the Norwegian public health-care context to reduce medication errors.
    A mixed method approach was used to gather data from participants working in the four regions served by the Norway health authorities. A survey questionnaire was distributed to 38 health-care practitioners and semi-structured interviews were conducted with 12 health-care practitioners.
    The study finds that the implementation of LSS in the Norwegian public health-care context is still in its infancy. This is amidst several challenges faced by Norwegian hospitals such as the lack of top-management support, lack of LSS training and coaching and a lack of awareness around the benefits of LSS in health care.
    Because of the large geographical area, it was difficult to reach participants from all health regions in Norway. However, the study managed to assess the current status of LSS implementation through the participants\' perspectives. This is a fruitful area for future research whereby an action research methodology could be used.
    To the best of the authors\' knowledge, this is the first empirical study into the use of LSS methodology in reducing medication errors. In addition, this study is valuable for health-care practitioners and professionals as a guideline to achieve the optimal benefit of LSS implementation to reduce medication errors.
