In this issue, Amalberti and Vincent1 ask ‘what strategies we might adopt to protect patients when healthcare systems and organizations are under stress and simply cannot provide the standard of care they aspire to’. This is clearly a critical and much overdue question, as many healthcare organisations are in an almost constant state of stress from high workload, personnel shortages, high-complexity patients, new technologies, fragmented and conflicting payment systems, over-regulation, and many other issues. These stressors put mid-level managers and front-line staff in situations where they may compromise their standards and be unable to provide the highest quality care. Such circumstances can contribute to low morale and burn-out.The authors provide guidance for addressing this tension of providing safe care during times of organisational stress, including principles for managing risk in difficult conditions, examples for managing this tension in other high-risk industries, and a research and development agenda for healthcare. Leaders at all levels of healthcare organisations should read this article.These authors join others2 who advise that we should shift our focus from creating absolute safety (meaning the elimination of error and harm) towards doing a better job of actively managing risk. I want to expand on this point to explore how an excessive focus on absolute safety may paradoxically reduce safety.Striving for absolute safety—often termed ‘zero harm’—is encouraged by some consultants, patient safety experts and regulators. Take for example the recently published book, ‘ Zero Harm: How to Achieve Patient and Workforce Safety in Healthcare ’ ,3 edited by three leaders of Press Ganey, a large organisation that works with over 26 000 healthcare organisations with the mission of helping organisations improve patient experience, including improving safety. The book states, ‘We will only reduce serious safety events, and improve organizations’ overall performance, if every US …
在本期中,Amalberti和Vincent1提出了一个问题:“当医疗保健系统和组织处于压力之下,无法提供他们期望的标准护理时,我们可以采取什么策略来保护患者?”这显然是一个重要且早该解决的问题,因为许多医疗保健组织几乎一直处于高工作量、人员短缺、高度复杂的患者、新技术、分散和冲突的支付系统、过度监管以及许多其他问题的压力状态。这些压力源使中层管理人员和一线工作人员可能会降低他们的标准,无法提供最高质量的护理。这种情况会导致士气低落和精疲力竭。作者为解决在组织压力时期提供安全护理的这种紧张关系提供了指导,包括在困难条件下管理风险的原则,在其他高风险行业管理这种紧张关系的例子,以及医疗保健的研究和开发议程。各级医疗机构的领导都应该阅读这篇文章。这些作者和其他人一起建议,我们应该把注意力从创造绝对安全(意味着消除错误和伤害)转向更好地主动管理风险。我想在这一点上展开探讨,过度关注绝对安全可能会自相矛盾地降低安全性。争取绝对安全——通常被称为“零伤害”——受到一些顾问、患者安全专家和监管机构的鼓励。以最近出版的书为例,“零伤害:如何实现医疗保健中的患者和劳动力安全”,3由Press Ganey的三位领导人编辑,Press Ganey是一家与超过26,000家医疗保健机构合作的大型组织,其使命是帮助组织改善患者体验,包括改善安全性。书中写道:“只有每个美国人……我们才能减少严重的安全事件,提高组织的整体绩效。”

Effective teamwork and communication is now recognised as a critical component of safe and high-quality patient care. Researchers, policymakers and frontline providers are in search of strategies to improve teamwork in healthcare. The most frequently used strategy is teamwork training.1 Teamwork training involves a systematic process in which a team is guided (often by facilitators) to improve and master different skills for working together effectively. Single-centre teamwork training initiatives have demonstrated improvements in patient care, but these results have been challenging to reproduce at scale.2 In this issue of BMJ Quality and Safety, Lenguerrand et al report the results of a stepped-wedge randomised controlled trial in which PRactical Obstetric Multi-Professional Training (PROMPT), an interprofessional intrapartum training package, was implemented across 12 maternity units in Scotland.3 Each participating unit identified an in-house training team to travel to attend a 2-day PROMPT Train the Trainers programme conducted in one simulation centre; two units were unable to send training teams. Training teams were subsequently responsible for coordinating the delivery of in-house PROMPT courses to all maternity staff within 12 months. The courses were intended to cover core obstetrical emergencies, such as postpartum haemorrhage, sepsis, shoulder dystocia, teamwork and fetal monitoring. In addition to clinical outcomes, each maternity unit collected process data about their local PROMPT courses, including the total number of staff trained and courses delivered and the actual course content. The authors found a significant amount of variability in the implementation across units. For example, all courses included elements of teamwork whereas fetal monitoring and shoulder dystocia training were not universally included. Despite the previously demonstrated benefits of PROMPT in single-centre studies, the final results did not demonstrate a reduction of term babies with a low Apgar score. The authors postulate this null finding may be in part related …
有效的团队合作和沟通现在被认为是安全和高质量患者护理的关键组成部分。研究人员、政策制定者和一线医疗服务提供者正在寻找改善医疗保健团队合作的策略。最常用的策略是团队合作培训。1团队合作培训涉及一个系统的过程,在这个过程中,团队(通常由辅导员)指导,以提高和掌握有效合作的不同技能。单中心团队合作培训计划已经证明了患者护理的改善,但这些结果很难大规模复制。2在本期《英国医学杂志质量与安全》中,Lenguerrand等人报道了一项阶梯式楔形随机对照试验的结果,在该试验中,产科多专业实践培训(PROMPT),一种跨专业的产时培训包,在苏格兰的12个产科单位实施。3每个参与单位都确定了一个内部培训小组,前往一个模拟中心参加为期两天的PROMPT培训员计划;两支部队无法派出训练队。培训小组随后负责协调在12个月内向所有产科工作人员提供内部PROMPT课程。这些课程旨在涵盖核心产科紧急情况,如产后出血、败血症、肩难产、团队合作和胎儿监护。除了临床结果外,每个产科单位还收集了当地PROMPT课程的流程数据,包括培训和提供课程的员工总数以及实际课程内容。作者发现,各单位在实施过程中存在很大的可变性。例如,所有课程都包含了团队合作的元素,而胎儿监护和肩部难产训练并没有普遍包括在内。尽管之前在单中心研究中证明了胎膜早破的好处,但最终结果并没有证明Apgar评分低的足月婴儿的减少。作者推测这一无效发现可能在一定程度上与…有关…

Is there a ‘best measure’ of patient safety? 是否存在患者安全的“最佳措施”?
Pub Date : 2019-10-08 DOI: 10.1136/bmjqs-2019-009730
A. Borzecki, A. Rosen
Despite consensus that preventing patient safety events is important, measurement of safety events remains challenging. This is, in part, because they occur relatively infrequently and are not always preventable. There is also no consensus on the ‘best way‘ or the ‘best measure’ of patient safety. The purpose of all safety measures is to improve care and prevent safety events; this can be achieved by different means. If the overall goal of measuring patient safety is to capture the universe of safety events that occur, then broader measures encompassing large populations, such as those based on administrative data, may be preferable. Acknowledging the trade-off between comprehensiveness and accuracy, such measures may be better suited for surveillance and quality improvement (QI), rather than public reporting/reimbursement. Conversely, using measures for public reporting and pay-for-performance requires more narrowly focused measures that favour accuracy over comprehensiveness, such as those with restricted denominators or those based on medical record review.There are at least two well-established patient safety measurement systems available for use in the inpatient setting, namely the administrative data-based Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSIs) and the medical record-based National Surgical Quality Improvement Programme (NSQIP) measures.1–3 The AHRQ PSIs, publicly released in 2003, are evidence-based measures designed to screen for potentially preventable medical and surgical complications that occur in the acute care setting. Since they use administrative data, they were originally designed as tools for use in case finding for local QI efforts and surveillance, as well as for internal hospital comparisons. They were developed using a rigorous process beginning with a thorough review of the literature for existing administrative data-based indicators, review by clinical expert panels, consultation with coding experts and empirical analyses to assess the statistical properties of the measures, such as reliability and predictive and …
尽管人们一致认为预防患者安全事件很重要,但安全事件的测量仍然具有挑战性。这在一定程度上是因为它们发生的相对较少,而且并不总是可以预防的。对于患者安全的“最佳方式”或“最佳措施”也没有达成共识。所有安全措施的目的是改善护理和预防安全事件;这可以通过不同的方式实现。如果测量患者安全性的总体目标是捕获发生的安全事件的范围,那么包括大量人口的更广泛的测量,例如基于管理数据的测量,可能是可取的。考虑到全面性和准确性之间的权衡,这些措施可能更适合于监督和质量改进(QI),而不是公开报告/报销。相反,使用公共报告和绩效工资的衡量标准需要更侧重于准确性而不是全面性的更狭隘的衡量标准,例如那些限制分母的衡量标准或基于医疗记录审查的衡量标准。至少有两种完善的患者安全测量系统可用于住院环境,即基于行政数据的医疗保健研究和质量机构(AHRQ)患者安全指标(psi)和基于医疗记录的国家外科质量改进计划(NSQIP)措施。1-3 2003年公开发布的AHRQ psi是基于证据的措施,旨在筛查在急性护理环境中发生的潜在可预防的医疗和手术并发症。由于它们使用的是管理数据,因此它们最初被设计为工具,用于地方卫生质量工作和监测的病例查找以及医院内部比较。它们是通过严格的过程开发的,首先是对现有基于行政数据的指标的文献进行彻底审查,由临床专家小组审查,与编码专家协商,并进行实证分析,以评估这些措施的统计特性,如可靠性、预测性和…

Objectives To examine how much of the variation between general practices in referral rates and cancer detection rates is attributable to local health services rather than the practices or their populations. Design Ecological analysis of national data on fast-track referrals for suspected cancer from general practices. Data were analysed at the levels of general practice, primary care organisation (Clinical Commissioning Group) and secondary care provider (Acute Hospital Trust) level. Analysis of variation in detection rate was by multilevel linear and Poisson regression. Setting 6379 group practices with data relating to more than 50 cancer cases diagnosed over the 5 years from 2013 to 2017. Outcomes Proportion of observed variation attributable to primary and secondary care organisations in standardised fast-track referral rate and in cancer detection rate before and after adjustment for practice characteristics. Results Primary care organisation accounted for 21% of the variation between general practices in the standardised fast-track referral rate and 42% of the unadjusted variation in cancer detection rate. After adjusting for standardised fast-track referral rate, primary care organisation accounted for 31% of the variation in cancer detection rate (compared with 18% accounted for by practice characteristics). In areas where a hospital trust was the main provider for multiple primary care organisations, hospital trusts accounted for the majority of the variation attributable to local health services (between 63% and 69%). Conclusion This is the first large-scale finding that a substantial proportion of the variation between general practitioner practices in referrals is attributable to their local healthcare systems. Efforts to reduce variation need to focus not just on individual practices but on local diagnostic service provision and culture at the interface of primary and secondary care.
目的研究转诊率和癌症检出率的一般做法之间的差异在多大程度上归因于当地卫生服务,而不是做法或人群。从一般实践中对疑似癌症的快速转诊的国家数据进行生态分析。在全科医生、初级保健组织(临床调试小组)和二级保健提供者(急性医院信托)层面对数据进行了分析。通过多水平线性和泊松回归分析检测率的变化。设置6379个团体实践,数据涉及5年内诊断出的50多例癌症病例 2013年至2017年。结果在对实践特征进行调整前后,标准化快速转诊率和癌症检测率中可归因于初级和二级护理组织的观察到的变化比例。结果在标准化快速转诊率的一般做法之间的差异中,初级保健组织占21%,在癌症检测率的未经调整的差异中占42%。在对标准化快速转诊率进行调整后,初级保健组织占癌症检测率变化的31%(相比之下,实践特征占18%)。在医院信托是多个初级保健组织的主要提供者的地区,医院信托占了当地卫生服务的大部分变化(63%至69%)。结论这是第一个大规模的发现,全科医生在转诊中的做法差异很大一部分可归因于当地的医疗系统。减少变异的努力不仅需要关注个人实践,还需要关注当地诊断服务的提供以及初级和次级护理的文化。

Background Training nurses in ultrasound-guided peripheral intravenous catheter placement might reduce the use of more invasive venous access devices (peripherally inserted central catheters (PICC) and midline catheters). Methods We implemented an abbreviated training in ultrasound-guided peripheral intravenous catheter placement for nurses on an inpatient medical unit and provided a portable ultrasound device for 10 months. Results Nurses on this unit placed 99 ultrasound-guided peripheral intravenous catheters with a high level of success. During the implementation period, PICC and midline catheter placement decreased from a mean 4.8 to 2.5 per month, meeting criteria for special cause variation. In the postimplementation period, the average catheter use reverted to 4.3 per month on the intervention unit. A comparison inpatient medical unit without training or access to a portable ultrasound device experienced no significant change in PICC and midline catheter use throughout the study period (mean of 6.0 per month). Conclusions These results suggest that an abbreviated training in ultrasound-guided peripheral intravenous catheter placement for nurses on an inpatient medical unit is sufficient to reduce PICC and midline catheters.
背景:对护士进行超声引导下外周静脉置管培训可能会减少侵入性静脉导管(外周中心导管和中线导管)的使用。方法对某住院部护士进行超声引导下外周静脉置管的简易培训,并提供便携式超声设备,为期10个月。结果超声引导下外周静脉留置导管99根,成功率高。在实施期间,PICC和中线导管放置从平均每月4.8例下降到2.5例,符合特殊原因变化的标准。在实施后,干预单元的平均导管使用恢复到每月4.3次。相比之下,在整个研究期间,没有接受培训或使用便携式超声设备的住院医疗单位,PICC和中线导管的使用没有显著变化(平均每月6.0次)。结论:对住院护士进行超声引导下外周静脉置管的简短培训足以减少PICC和中线置管。

Preventing Clostridioides difficile infection in hospitals: what is the endgame? 在医院预防艰难梭菌感染:结局是什么?
Pub Date : 2019-10-03 DOI: 10.1136/bmjqs-2019-009953
S. Hota, M. Doll, G. Bearman
Clostridioides difficile infection (CDI) remains an important healthcare-associated infection and threat to patient safety since the height of the NAP1/027 epidemic in the early part of the millennium. In 2011, C. difficile caused almost half a million infections and 29 000 deaths in the USA alone, with 24% of those cases occurring in hospital settings.1 The US Centres for Disease Control identifies C. difficile as one of three pathogens that poses ‘an immediate antibiotic resistance threat that requires urgent and aggressive action’.2 Many jurisdictions now require public reporting of hospital CDI rates. In some countries, hospitals face financial penalties for elevated CDI rates. CDI rates are also top priorities on hospital quality agendas, often associated with ambitious reduction targets. Some institutions even aim for complete elimination of healthcare-associated CDI—a goal referred to as ‘getting to zero’.There is no argument that healthcare-associated CDI is a significant patient safety issue and that aggressive efforts should be taken to prevent its harmful effects. However, external pressures and a lack of appreciation for the complexity of C. difficile epidemiology are interfering with the mission to prevent healthcare-associated CDI. We expose the challenges of the current approach to CDI prevention in hospitals and highlight where prevention efforts deserve further attention.With the focus on reducing CDI rates, diagnostic test stewardship for CDI is a popular quality improvement initiative in hospitals. Typical symptoms for CDI—diarrhoea and abdominal pain—are common in hospitalised patients due to comorbidities, medication exposures (including laxatives) and initiation of enteral feeds.

自本世纪初NAP1/027疫情最严重以来,艰难梭菌感染(CDI)仍然是一种重要的医疗保健相关感染,对患者安全构成威胁。2011年,艰难梭菌导致近50万人感染,29人感染 仅在美国就有1000人死亡,其中24%发生在医院环境中。1美国疾病控制中心将艰难梭菌确定为三种病原体之一,它们构成了“需要紧急和积极行动的直接抗生素耐药性威胁”。2许多司法管辖区现在要求公开报告医院CDI发病率。在一些国家,医院因CDI发病率升高而面临经济处罚。CDI率也是医院质量议程上的首要任务,通常与雄心勃勃的减排目标有关。一些机构甚至致力于彻底消除与医疗保健相关的CDI,这一目标被称为“清零”。毫无疑问,与医疗保健有关的CDI是一个重大的患者安全问题,应该采取积极措施防止其有害影响。然而,外部压力和对艰难梭菌流行病学复杂性的缺乏认识正在干扰预防医疗保健相关CDI的任务。我们揭示了当前医院CDI预防方法的挑战,并强调了预防工作值得进一步关注的地方。随着对降低CDI发病率的关注,CDI的诊断测试管理是医院中一项受欢迎的质量改进举措。CDI的典型症状——腹泻和腹痛——在住院患者中很常见,原因是合并症、药物暴露(包括泻药)和开始肠内喂养。再加上越来越多地使用高灵敏度的艰难梭菌分子检测,多达一半的受调查者过度诊断了CDI。3因此,存在算法来阻止对腹泻其他病因患者进行检测。诊断性艰难梭菌检测管理可能有助于提高准确的病例数…

In 2011, C. difficile caused almost half a million infections and 29 000 deaths in the USA alone, with 24% of those cases occurring in hospital settings.1 The US Centres for Disease Control identifies C. difficile as one of three pathogens that poses ‘an immediate antibiotic resistance threat that requires urgent and aggressive action’.2 Many jurisdictions now require public reporting of hospital CDI rates. In some countries, hospitals face financial penalties for elevated CDI rates. CDI rates are also top priorities on hospital quality agendas, often associated with ambitious reduction targets. Some institutions even aim for complete elimination of healthcare-associated CDI—a goal referred to as ‘getting to zero’.\u0000\u0000There is no argument that healthcare-associated CDI is a significant patient safety issue and that aggressive efforts should be taken to prevent its harmful effects. However, external pressures and a lack of appreciation for the complexity of C. difficile epidemiology are interfering with the mission to prevent healthcare-associated CDI. We expose the challenges of the current approach to CDI prevention in hospitals and highlight where prevention efforts deserve further attention.\u0000\u0000With the focus on reducing CDI rates, diagnostic test stewardship for CDI is a popular quality improvement initiative in hospitals. Typical symptoms for CDI—diarrhoea and abdominal pain—are common in hospitalised patients due to comorbidities, medication exposures (including laxatives) and initiation of enteral feeds.

Background Experience-based codesign (EBCD) is an approach to health service design that engages patients and healthcare staff in partnership to develop and improve health services or pathways of care. The aim of this systematic review was to examine the use (structure, process and outcomes) and reporting of EBCD in health service improvement activities. Methods Electronic databases (MEDLINE, CINAHL, PsycINFO and The Cochrane Library) were searched to identify peer-reviewed articles published from database inception to August 2018. Search terms identified peer-reviewed English language qualitative, quantitative and mixed methods studies that underwent independent screening by two authors. Full texts were independently reviewed by two reviewers and data were independently extracted by one reviewer before being checked by a second reviewer. Adherence to the 10 activities embedded within the eight-stage EBCD framework was calculated for each study. Results We identified 20 studies predominantly from the UK and in acute mental health or cancer services. EBCD fidelity ranged from 40% to 100% with only three studies satisfying 100% fidelity. Conclusion EBCD is used predominantly for quality improvement, but has potential to be used for intervention design projects. There is variation in the use of EBCD, with many studies eliminating or modifying some EBCD stages. Moreover, there is no consistency in reporting. In order to evaluate the effect of modifying EBCD or levels of EBCD fidelity, the outcomes of each EBCD phase (ie, touchpoints and improvement activities) should be reported in a consistent manner. Trial registration number CRD42018105879.
背景基于经验的代码设计(EBCD)是一种医疗服务设计方法,它让患者和医护人员合作开发和改进医疗服务或护理途径。这项系统审查的目的是检查EBCD在卫生服务改进活动中的使用(结构、过程和结果)和报告。方法检索电子数据库(MEDLINE、CINAHL、PsycINFO和The Cochrane Library),以确定从数据库成立到2018年8月发表的同行评审文章。搜索词确定了同行评审的英语定性、定量和混合方法研究,这些研究由两位作者进行了独立筛选。全文由两名评审员独立评审,数据由一名评审员单独提取,然后由第二名评审员检查。每项研究都计算了对八阶段EBCD框架内10项活动的遵守情况。结果我们确定了20项主要来自英国和急性精神健康或癌症服务的研究。EBCD的保真度在40%到100%之间,只有三项研究满足100%的保真度。结论EBCD主要用于质量改进,但有潜力用于干预设计项目。EBCD的使用存在差异,许多研究消除或修改了一些EBCD阶段。此外,报告也不一致。为了评估修改EBCD或EBCD保真度水平的效果,应以一致的方式报告每个EBCD阶段的结果(即接触点和改进活动)。试验注册号CRD42018105879。

Background Socioeconomic status affects surgical outcomes, however these factors are not included in clinical quality improvement data and risk models. We performed a prospective registry analysis to determine if the Distressed Communities Index (DCI), a composite socioeconomic ranking by zip code, could predict risk-adjusted surgical outcomes and resource utilisation. Methods All patients undergoing surgery (n=44,451) in a regional quality improvement database (American College of Surgeons-National Surgical Quality Improvement Program ACS-NSQIP) were paired with DCI, ranging from 0–100 (low to high distress) and accounting for unemployment, education level, poverty rate, median income, business growth and housing vacancies. The top quartile of distress was compared to the remainder of the cohort and a mixed effects modeling evaluated ACS-NSQIP risk-adjusted association between DCI and the primary outcomes of surgical complications and resource utilisation. Results A total of 9369 (21.1%) patients came from severely distressed communities (DCI >75), who had higher rates of most medical comorbidities as well as transfer status (8.4% vs 4.8%, p<0.0001) resulting in higher ACS-NSQIP predicted risk of any complication (8.0% vs 7.1%, p<0.0001). Patients from severely distressed communities had increased 30-day mortality (1.8% vs 1.4%, p=0.01), postoperative complications (9.8% vs 8.5%, p<0.0001), hospital readmission (7.7 vs 6.8, p<0.0001) and resource utilisation. DCI was independently associated with postoperative complications (OR 1.07, 95% CI 1.04 to 1.10, p<0.0001) as well as resource utilisation after adjusting for ACS-NSQIP predicted risk Conclusion Increasing Distressed Communities Index is associated with increased postoperative complications and resource utilisation even after ACS-NSQIP risk adjustment. These findings demonstrate a disparity in surgical outcomes based on community level socioeconomic factors, highlighting the continued need for public health innovation and policy initiatives.
背景:社会经济地位影响手术结果,但这些因素不包括在临床质量改善数据和风险模型中。我们进行了一项前瞻性登记分析,以确定贫困社区指数(DCI),一个由邮政编码组成的综合社会经济排名,是否可以预测风险调整后的手术结果和资源利用。方法在区域质量改进数据库(美国外科医师学会-国家外科质量改进计划ACS-NSQIP)中对所有手术患者(n=44,451)进行DCI配对,DCI评分范围为0-100(低至高窘迫),并考虑失业、教育水平、贫困率、收入中位数、业务增长和住房空置率。将困扰的前四分之一患者与队列的其余患者进行比较,并采用混合效应模型评估ACS-NSQIP风险调整后DCI与手术并发症和资源利用的主要结局之间的关联。结果9369例(21.1%)患者来自危重社区(DCI bb0.75),其大部分医疗合并症和转院状况的发生率较高(8.4%比4.8%,p<0.0001),导致ACS-NSQIP预测并发症的风险较高(8.0%比7.1%,p<0.0001)。来自严重贫困社区的患者30天死亡率(1.8% vs 1.4%, p=0.01)、术后并发症(9.8% vs 8.5%, p<0.0001)、再入院率(7.7 vs 6.8, p<0.0001)和资源利用率均有所增加。调整ACS-NSQIP预测风险后,DCI与术后并发症(OR 1.07, 95% CI 1.04 ~ 1.10, p<0.0001)以及资源利用率独立相关。结论:即使在ACS-NSQIP风险调整后,贫困社区指数的增加仍与术后并发症和资源利用率的增加相关。这些发现表明,基于社区层面的社会经济因素,手术结果存在差异,突出了公共卫生创新和政策举措的持续必要性。

Identifying and quantifying variation between healthcare organisations and geographical regions: using mixed-effects models 识别和量化医疗保健组织和地理区域之间的差异:使用混合效应模型

G. Abel, M. Elliott
When the degree of variation between healthcare organisations or geographical regions is quantified, there is often a failure to account for the role of chance, which can lead to an overestimation of the true variation. Mixed-effects models account for the role of chance and estimate the true/underlying variation between organisations or regions. In this paper, we explore how a random intercept model can be applied to rate or proportion indicators and how to interpret the estimated variance parameter.
当量化医疗保健组织或地理区域之间的差异程度时,往往没有考虑到机会的作用,这可能会导致对真实差异的高估。混合效应模型考虑了机会的作用,并估计了组织或地区之间的真实/潜在变化。在本文中,我们探讨了如何将随机截距模型应用于比率或比例指标,以及如何解释估计的方差参数。
