    一位女性患者,已知患有超机动Ehlers-Danlos综合征(hEDS),在不同医院的镇静下接受了几次选择性胃镜检查。除了在出现时发生了一次轻度喉痉挛,所有程序都很顺利。在那个场合,按照麻醉后监护室的程序,患者出现严重的气道阻塞,标准的气道救援技术加剧了充分的通气。在消除所有刺激并仅通过面罩在她面前保持间接氧气供应之后,她的气道改善了,17分钟后患者完全康复。胃镜检查后,体格检查显示,病人有一个非常灵活的气管,可以完全移动到中线之外,向右和向左。对于后续程序,与患者一起制定了气道计划,并导致了简单的麻醉护理。此病例报告旨在提醒读者EDS患者发生不良气道事件的风险,并提出了避免此类并发症的替代方法。当病人在不同的医院接受治疗时,充分的文献记录是必要的,充分的术前评估是至关重要的.此案例研究证明了患者共同生产护理计划的价值。
    A female patient, known to have hypermobile Ehlers-Danlos syndrome (hEDS), underwent several elective gastroscopies under sedation in different hospitals. Except for a single incident of mild laryngospasm during emergence, all procedures were uneventful. On that occasion, following the procedure in the postanesthesia care unit, the patient suffered severe airway obstruction, and standard airway rescue techniques exacerbated adequate ventilation. After the removal of all stimuli and maintaining only an indirect oxygen supply via a mask in front of her face, her airway improved, and the patient fully recovered after 17 minutes. After the gastroscopy, physical examination revealed that the patient had an extremely flexible trachea that could be completely moved outside the midline to the extreme right and left. For the subsequent procedures, an airway plan was developed in conjunction with the patient and resulted in uncomplicated perianesthetic care. This case report serves to alert readers to the risk of adverse airway events in patients with EDS and suggests an alternative approach to avoid such complications. When patients receive care in different hospitals, adequate documentation is essential and adequate preoperative assessment is crucial. This case study demonstrates the value of patient-coproduction care plans.

    背景:联合生产的创新正在塑造世界各地不同背景下的公共服务改革。虽然许多创新是本地的,其他人随着时间的推移而扩大和发展。我们知道的很少,然而,关于联合生产的实施和演变过程。这项研究的目的是探索采用,实施和吸收三种与结构弱势群体共同生产公共服务的方法。
    方法:我们对涉及弱势群体的三个联合生产的公共服务创新进行了为期4年的纵向多案例研究(2019-2023年):延雪平地区的ESTHER,瑞典涉及具有多种复杂需求的人(案例1);在邓迪实现恢复,苏格兰有严重精神疾病的人(案例2);和曼尼托巴省的学习中心,加拿大(案例3),还涉及患有严重精神疾病的人。数据来源包括对战略决策者的14次访谈和文件分析,以了解与每个案例有关的历史和环境因素。三个框架为案例研究协议提供了信息,半结构化面试指南,数据提取,演绎编码与分析:实施研究的综合框架,创新模型的扩散与Lozeau理解同化的兼容性差距。
    结果:采用涉及结构脆弱人群的共同生产是案例1和案例3中现有改进工作的显着演变,同时由外部变更机构推动,社区组织之间现有的合作努力,在案例2中,有机会告知新的市政精神卫生政策引发了采用。在所有情况下,共同生产的创新围绕着一个中心理念,重视生活经验与共同生产过程中的专业知识。这种哲学取向为当地环境提供了灵活性和适应性,因此,与更多定义的编程相比,便于实现。据告密者说,避免合作风险的努力取得了成功,导致新思维方式和共同生产过程的同化,并举例说明了这是如何导致变革性变化的。
    结论:在探索与结构脆弱群体共同生产的创新时,我们的研究结果提出了在应用现有理论框架时需要考虑的几个额外因素.这些包括创新的哲学性质,需要研究创新本身随着时间的推移而演变的过程,更多关注合作过程作为现有权力结构的破坏者,并强调推动组织文化的转型变革。
    BACKGROUND: Innovations in coproduction are shaping public service reform in diverse contexts around the world. Although many innovations are local, others have expanded and evolved over time. We know very little, however, about the process of implementation and evolution of coproduction. The purpose of this study was to explore the adoption, implementation and assimilation of three approaches to the coproduction of public services with structurally vulnerable groups.
    METHODS: We conducted a 4 year longitudinal multiple case study (2019-2023) of three coproduced public service innovations involving vulnerable populations: ESTHER in Jönköping Region, Sweden involving people with multiple complex needs (Case 1); Making Recovery Real in Dundee, Scotland with people who have serious mental illness (Case 2); and Learning Centres in Manitoba, Canada (Case 3), also involving people with serious mental illness. Data sources included 14 interviews with strategic decision-makers and a document analysis to understand the history and contextual factors relating to each case. Three frameworks informed the case study protocol, semi-structured interview guides, data extraction, deductive coding and analysis: the Consolidated Framework for Implementation Research, the Diffusion of Innovation model and Lozeau\'s Compatibility Gaps to understand assimilation.
    RESULTS: The adoption of coproduction involving structurally vulnerable populations was a notable evolution of existing improvement efforts in Cases 1 and 3, while impetus by an external change agency, existing collaborative efforts among community organizations, and the opportunity to inform a new municipal mental health policy sparked adoption in Case 2. In all cases, coproduced innovation centred around a central philosophy that valued lived experience on an equal basis with professional knowledge in coproduction processes. This philosophical orientation offered flexibility and adaptability to local contexts, thereby facilitating implementation when compared with more defined programming. According to the informants, efforts to avoid co-optation risks were successful, resulting in the assimilation of new mindsets and coproduction processes, with examples of how this had led to transformative change.
    CONCLUSIONS: In exploring innovations in coproduction with structurally vulnerable groups, our findings suggest several additional considerations when applying existing theoretical frameworks. These include the philosophical nature of the innovation, the need to study the evolution of the innovation itself as it emerges over time, greater attention to partnered processes as disruptors to existing power structures and an emphasis on driving transformational change in organizational cultures.

    背景:患有精神病的个体经历广泛的治疗失败并有早期死亡的风险。瑞典最大的专门研究精神病的部门试图通过开发一个即时护理仪表板来支持联合计划和共同生产护理来改善患者的健康。仪表板经过18个月的测试,包括两个门诊诊所的400多名患者。
    方法:本研究通过解决两个问题来评估仪表板:1)与健康相关的结果测量的差异是否可以归因于仪表板的使用?2)案例管理者如何体验可访问性,使用,与精神病患者共同生产护理的仪表板的有用性?这个混合方法案例研究使用了患者报告的结果测量(PROM)和来自病例经理焦点小组访谈的数据。数据收集和分析由临床采用荟萃模型(CAMM)阶段构成:i)可及性,ii)系统使用,iii)行为,和iv)临床结果。使用的PROM是12项世界卫生组织残疾评估表(WHODAS2.0),评估功能障碍和残疾。使用仪表板的诊所患者与不使用仪表板的诊所患者相匹配。由于分布偏度,使用非参数统计比较了PROM数据。焦点小组包括五名病例经理,他们有与患者一起使用仪表板的经验。
    结果:与未使用仪表板的诊所的患者相比,使用仪表板的诊所患者总体上(p=0.045)和领域自我护理(p=0.041)显著改善.焦点小组参与者报告说,仪表板支持数据反馈知情护理和与患者健康变化相关的积极立场。仪表板帮助用户识别关键变更,并实现联合规划和评估。
    结论:与未使用仪表板的诊所的匹配患者相比,使用仪表板与更好的患者健康状况(WHODAS评分)相关。此外,案例经理使用仪表板有一个积极的经验。仪表板的使用可能降低了错过患者健康关键变化的风险,同时提高了主动满足需求的能力。未来的研究应研究如何通过使用支持技术来增强患者的共同生产。
    BACKGROUND: Individuals with psychotic disorders experience widespread treatment failures and risk early death. Sweden\'s largest department specializing in psychotic disorders sought to improve patients\' health by developing a point-of-care dashboard to support joint planning and co-production of care. The dashboard was tested for 18 months and included more than 400 patients at two outpatient clinics.
    METHODS: This study evaluates the dashboard by addressing two questions: 1) Can differences in health-related outcome measures be attributed to the use of the dashboard? 2) How did the case managers experience the accessibility, use, and usefulness of the dashboard for co-producing care with individuals with psychotic disorders? This mixed-method case study used both Patient-Reported Outcome Measures (PROM) and data from a focus group interview with case managers. Data collection and analysis were framed by the Clinical Adoption Meta Model (CAMM) phases: i) accessibility, ii) system use, iii) behavior, and iv) clinical outcomes. The PROM used was the 12-item World Health Organization Disability Assessment Schedule (WHODAS 2.0), which assesses functional impairment and disability. Patients at clinics using the dashboard were matched with patients at clinics not using the dashboard. PROM data were compared using non-parametric statistics due to skewness in distribution. The focus group included five case managers who had experience using the dashboard with patients.
    RESULTS: Compared to patients from clinics that did not use the dashboard, patients from clinics that did use the dashboard improved significantly overall (p = 0.045) and in the domain self-care (p = 0.041). Focus group participants reported that the dashboard supported data feedback-informed care and a proactive stance related to changes in patients\' health. The dashboard helped users identify critical changes and enabled joint planning and evaluation.
    CONCLUSIONS: Dashboard use was related to better patient health (WHODAS scores) when compared with matched patients from clinics that did not use the dashboard. In addition, case managers had a positive experience using the dashboard. Dashboard use might have lowered the risk for missing critical changes in patients\' health while increasing the ability to proactively address needs. Future studies should investigate how to enhance patient co-production through use of supportive technologies.

    本文旨在探讨个人共同生产的挑战,团队,服务,组织和系统级别,并严格描述了一个组织的工作,以描述可以促进联合生产的方式。
    这是一个案例研究,研究了在一个独立的非营利性心理健康咨询机构中开发(共同生产)的方法,以促进各个层面的共同生产。
    尽管在研究中发表了很多关于联合生产的文章,在实践中,关于联合生产的指导相对较少。本文阐述了本文的意义,不同层次联产的目的和影响,并举例说明如何实现联产。从他的工作中吸取的经验教训汇集在一起,提出了一系列调查结果,并提出了建议,包括:管理功率差异,容纳差异,产生新的前进方式,而不是辩论和选择现有的选项。
    关于在实践中联合生产的文献充满了指导,而不是良好实践的例子。显然,联合生产的雄心已经从服务提供商和使用服务的人之间的联合生产到与所有相关利益相关者的联合生产迅速发展。本文提供了以不同形式和不同级别的共同生产的当代示例,并关注克服挑战的方法。
    This paper aims to explore the challenges of coproduction at individual, team, service, organisational and system level and critically describes the work of one organization to describe ways in which coproduction can be facilitated.
    This is a case study of the approaches developed (coproduced) within an independent not-for-profit mental health consultancy organization to facilitate coproduction at every level.
    Although much is published about coproduction in research, there is relatively little guidance relating to coproduction in practice. This paper describes the meaning, purpose and impact of coproduction at different levels and gives examples of how it can be achieved. The learning from his work is drawn together to present a series of findings with recommendations including: inclusion, managing power difference, accommodating difference, generating new ways forward rather than debating and selecting existing options.
    The literature on coproduction in practice is replete with guidance rather than examples of good practice. It is also apparent that the ambition for coproduction has progressed rapidly from coproduction between service providers and people using services to coproduction with all relevant stakeholders. This paper provides contemporary examples of coproduction in different forms and at different levels with attention to ways of overcoming challenges.

    这项研究旨在对志愿者计划进行成本效益分析。文献缺乏关于公共部门背景下志愿工作成本效率的经验证据。以前的研究大多关注非营利组织的案例,尽管公共组织中有许多志愿者计划。在这项研究中,我们专注于美国海岸警卫队辅助船船员计划,该计划可能会帮助陷入困境的船民,巡逻帆船赛和海上活动,并协助海上观测。我们发现,大约有139万美元投资于志愿者,以运行2019年的船员计划。我们还使用重置成本法估算了志愿者捐款的总货币收益。因此,我们发现,5369名志愿者在2019年为船员计划贡献了约199,000小时。这意味着该计划在2019年扩展了相当于104名全职海岸警卫队人员的人数。志愿者贡献的总经济利益从480万美元到540万美元不等。因此,海岸警卫队在志愿者项目上投入的每一美元,他们从志愿者捐款中获得了3.42美元至3.89美元的额外回报。
    This research aimed to conduct a cost-benefit analysis of a volunteer program. The literature lacked empirical evidence on the cost efficiency of voluntary work in the public-sector context. Most previous studies have paid attention to the cases of nonprofit organizations, although there have been many volunteer programs in public organizations. In this research, we focused on the United States Coast Guard Auxiliary Boat Crew Program which may help distressed boaters in distress, patrol regattas and marine events, and assist in maritime observations. We discovered that approximately $1.39 million was invested in volunteers to run the boat crew program for 2019. We also estimated the total monetary benefit of volunteer contributions by using the replacement cost method. As a result, we found that 5369 volunteers contributed approximately 199,000 h to the boat crew program in 2019. It means that the program extended the equivalent of 104 full-time Coast Guard personnel in 2019. The total economic benefit attributed to the volunteer contributions of labor ranged from $4.8 million to $5.4 million. Therefore, for every dollar the Coast Guard invested in the volunteer program, they obtained an additional return of $3.42 to $3.89 from volunteer contributions.

    背景:移民妇女使用不太有效的避孕方法,并且意外怀孕的风险更高。孕产妇保健服务为加强避孕服务提供了一个中心机会,尤其是移民。本研究旨在评估质量改进协作QIC。其目标是改善产后移民妇女的避孕服务,通过卫生保健专业人员(HCPs)咨询和更有效的避孕方法选择。
    方法:试点研究被设计为组织案例研究,包括定性和定量数据收集和分析。斯德哥尔摩三个孕产妇保健诊所(MHCs)的助产士,瑞典在2018-2019年期间参加了QIC。此外,两名最近怀孕的妇女和一对夫妇提供了用户反馈。关于妇女在产后就诊时选择避孕方法的数据在瑞典妊娠登记册中登记了1年以上。
    结果:参与的助产士决定增加移民妇女在产后选择更有效避孕方法的比例将是QIC的目标。避孕服务的循证变化,由用户反馈支持,在三个动作期间在临床实践中进行了测试。在QIC期间,在QIC早期,选择产后更有效避孕方法的女性比例增加。在移民妇女中,在研究期间,选择更有效的避孕方法的比例从30%增加到47%.助产士报告说,由于参加了QIC,他们的咨询技能得到了发展,他们发现使用一个有利于评估妇女选择避孕方法的登记册。
    结论:QIC,由注册和用户反馈支持,帮助助产士在怀孕和产后改善避孕服务。在QIC期间,移民妇女对产后更有效避孕方法的选择增加。这意味着QIC可以增加移民选择更有效的产后避孕方法。
    BACKGROUND: Immigrant women use less effective contraceptive methods and have a higher risk of unintended pregnancies. Maternal health care services offer a central opportunity to strengthen contraceptive services, especially among immigrants. This study aimed to evaluate a Quality Improvement Collaborative QIC. Its objective was to improve contraceptive services for immigrant women postpartum, through health care professionals\' (HCPs) counselling and a more effective choice of contraceptive methods.
    METHODS: The pilot study was designed as an organisational case study including both qualitative and quantitative data collection and analysis. Midwives at three maternal health clinics (MHCs) in Stockholm, Sweden participated in a QIC during 2018-2019. In addition, two recently pregnant women and a couple contributed user feedback. Data on women\'s choice of contraceptive method at the postpartum visit were registered in the Swedish Pregnancy Register over 1 year.
    RESULTS: The participating midwives decided that increasing the proportion of immigrant women choosing a more effective contraceptive method postpartum would be the goal of the QIC. Evidence-based changes in contraceptive services, supported by user feedback, were tested in clinical practice during three action periods. During the QIC, the proportion of women choosing a more effective contraceptive method postpartum increased at an early stage of the QIC. Among immigrant women, the choice of a more effective contraception increased from 30 to 47% during the study period. Midwives reported that their counselling skills had developed due to participation in the QIC, and they found using a register beneficial for evaluating women\'s choice of contraceptive methods.
    CONCLUSIONS: The QIC, supported by a register and user feedback, helped midwives to improve their contraceptive services during the pregnancy and postpartum periods. Immigrant women\'s choice of a more effective contraceptive method postpartum increased during the QIC. This implies that a QIC could increase the choice of a more effective contraception of postpartum contraception among immigrants.

    背景:响应,综合和可持续的卫生系统要求社区在服务设计和提供中发挥积极作用。当前的许多文献都集中在提供者主导的举措上,以获得社区投入,引起人们对邀请参与形式固有的权力失衡的担忧。本文提供了另一种观点,探索如何,在改革后的一段时间里,社区行为者建立网络联盟,以(重新)获得与系统提供者共同生产卫生服务的合法性和能力。
    方法:一项纵向案例研究追踪了由公民和社区行为者与老年人合作组成的工作组在3年中的网络建设工作。少数民族,最近的移民,青年和残疾人。该小组聚集在一起,担心改革会影响获得医疗服务的机会,以及社区团体调解弱势社区居民获得医疗服务的能力。数据来自对小组会议和活动的观察,在小组内部和由小组分发的文件,半定向采访。第一阶段分析使用社交网络映射来揭示工作组实现的网络发展;第二阶段跟踪网络成熟,基于行动者网络理论。
    结果:网络映射揭示了工作组如何调动现有链接并与卫生系统参与者建立新链接以探索访问问题。在破坏现有合作关系并引入新结构和流程的改革背景下,问题化似乎是网络发展中一个特别重要的阶段。
    结论:网络建设战略使社区行为者能够提高其联合生产能力。关键贡献在于创建“组织基础架构”。
    UNASSIGNED:首席研究员参与社区团体和社区居民的活动超过3年。一些小组成员对本文的初稿提出了意见。为了保持团体的匿名性,他们的名字不会出现在确认部分。
    BACKGROUND: Responsive, integrated and sustainable health systems require that communities take an active role in service design and delivery. Much of the current literature focuses on provider-led initiatives to gain community input, raising concerns about power imbalances inherent in invited forms of participation. This paper provides an alternate view, exploring how, in a period following reforms, community actors forge network alliances to (re)gain legitimacy and capacities to coproduce health services with system providers.
    METHODS: A longitudinal case study traced the network-building efforts over 3 years of a working group formed by citizens and community actors working with seniors, minorities, recent immigrants, youth and people with disabilities. The group came together over concerns about reforms that impacted access to health services and the ability of community groups to mediate access for vulnerable community residents. Data were collected from observation of the group\'s meetings and activities, documents circulated within and by the group, and semi-directed interviews. The first stage of analysis used social network mapping to reveal the network development achieved by the working group; a second traced network maturation, based on actor-network theory.
    RESULTS: Network mapping revealed how the working group mobilized existing links and created new links with health system actors to explore access issues. Problematization appeared as an especially important stage in network development in the context of reforms that disrupted existing collaborative relationships and introduced new structures and processes.
    CONCLUSIONS: Network-building strategies enable community actors to enhance their capacity for coproduction. A key contribution lies in the creation of \'organizational infrastructure\'.
    UNASSIGNED: The lead researcher was embedded over 3 years in the activities of the community groups and community residents. Several group members provided comments on an initial draft of this paper. To preserve the anonymity of the group, their names do not appear in the acknowledgements section.

    It is becoming increasingly clear that the field of empirical bioethics requires methodological innovations that can keep up with the scale and pace of contemporary research in health and medicine. With that in mind, we have recently argued for Design Bioethics-the use of purpose-built, engineered research tools that allow researchers to investigate moral decision-making in ways that are embodied and contextualized. In this paper, we outline the development, testing and implementation of a novel prototype tool in the Design Bioethics Workshop-with each step illustrated with collected data. Titled \'Tracing Tomorrow\' (www.tracingtomorrow.org), the tool is a narrative game to investigate young people\'s values and preferences in the context of digital phenotyping for mental health. The process involved (1) Working with young people to discover, validate and define the morally relevant cases or problems, (2) Building and testing the game concept in collaboration with relevant groups and game developers, (3) Developing prototypes that were tested and iterated in partnership with groups of young people and game developers and (4) Disseminating the game to young people to collect data to investigate research questions. We argue that Design Bioethics yields tools that are relevant, representative and meaningful to target populations and provide improved data for bioethics analysis. PATIENT OR PUBLIC CONTRIBUTION: In planning and conducting this study, we consulted with young people from a diverse range of backgrounds, including the NeurOX Young People\'s Advisory Group, the What Lies Ahead Junior Researchers Team, Censuswide youth participants and young people from the Livity Youth Network.

    Dutch policy stipulates that people with dementia should remain at home for as long as possible. If they need care, they must preferably appeal to family, friends and neighbours. Professional help and nursing homes are deemed last resorts. Therefore, case managers must coproduce their public services increasingly in healthcare triads with both people with dementia (PWDs) and their informal caregivers. Case managers are professionals who provide and coordinate care and support for PWDs and their informal caregivers during the entire trajectory from (suspected) diagnosis until institutionalisation. The literature on coproduction has focused on the bilateral interactions between service providers and users rather than the multilateral collaborative relationships through which many public services are currently delivered, as is the case in dementia care. Little is known about how frontline workers, case managers in this study, handle conflicts in these healthcare triads. Our study addresses this gap in the coproduction literature and explores the action strategies case managers use to handle conflicts. We interviewed 19 Dutch case managers and observed 10 of their home visits between January and May 2017. We focused on the end stage of dementia at home, just before admission to a nursing home, as we assumed that most conflicts occur in that phase. The findings reveal that the case managers use a variety of action strategies to resolve and intervene in these conflicts. Their initial strategies are in line with the ideals underlying coproduction; however, their successive strategies abandon those ideals and are more focused on production or result from their own lack of power. We also found that current reforms create new dilemmas for case managers. Future research should focus on the boundaries of coproducing public services in triadic relationships and the effects of current welfare reforms aimed at coproducing public services in healthcare triads.

    对灾难文献的回顾表明,对流行病的应急反应往往没有得到充分研究;当前的COVID-19危机为提高对这种疾病和其他传染性和破坏性疾病的认识和理解提供了一个重要机会。考虑到这一点,这项研究检查了台湾对COVID-19的反应,因为尽管感染的可能性很高,但它还是成功的。本文首先探讨了认知,通信,合作,和控制对于有效的灾难响应至关重要;然后,它表明需要考虑两个额外的C:信心(对政府能力的信任)和共同生产(公众参与预防灾难传播)。本文还对台湾政府的反应时间表进行了定性的描述性研究,并举例说明了这些行动中的每个概念。为了进一步说明需要两个额外的Cs,调查数据表明,在预防COVID-19传播方面,公众信心是如何在政府的COVID-19反应和公民共同生产之间发挥核心作用的。
    A review of the disaster literature indicates that emergency responses to pandemics are often understudied; the current COVID-19 crisis provides an important opportunity to improve awareness and understanding about this and other contagious and disruptive diseases. With this in mind, this study examines Taiwan\'s response to COVID-19 because it was successful in spite of a high probability of contagion. The paper first explores the assertion that cognition, communication, collaboration, and control are vital for effective disaster response; it then indicates the need to consider two additional Cs: confidence (trust of government\'s competency) and coproduction (public participation in disaster transmission prevention). The paper also conducts a qualitative descriptive study of the Taiwan government\'s response timeline with examples of each of these concepts in action. To further illustrate the need for the two additional Cs, survey data illustrate how public confidence serves as a pivot between government\'s COVID-19 response and citizen coproduction in COVID-19 transmission prevention.
