ABSTRACT Background: There is a growing concern that reduction in hospital length of stay (LOS) may raise the rate of hospital readmission. This study aims to identify the rate of avoidable 30-day readmission and find out the association between LOS and readmission. Methods: All consecutive patient admissions to the internal medicine services (n = 5,273) at King Abdullah University Hospital in Jordan between 1 December 2012 and 31 December 2013 were analyzed. To identify avoidable readmissions, a validated computerized algorithm called SQLape was used. The multinomial logistic regression was firstly employed. Then, detailed analysis was performed using the Decision Trees (DTs) model, one of the most widely used data mining algorithms in Clinical Decision Support Systems (CDSS). Results: The potentially avoidable 30-day readmission rate was 44%, and patients with longer LOS were more likely to be readmitted avoidably. However, LOS had a significant negative effect on unavoidable readmissions. Conclusions: The avoidable readmission rate is still highly unacceptable. Because LOS potentially increases the likelihood of avoidable readmission, it is still possible to achieve a shorter LOS without increasing the readmission rate. Moreover, the way the DT model classified patient subgroups of readmissions based on patient characteristics and LOS is applicable in real clinical decisions.
摘要背景:越来越多的人担心住院时间(LOS)的减少可能会增加再入院率。本研究旨在确定可避免的30天再入院率,并找出LOS与再入院之间的关系。方法:分析2012年12月1日至2013年12月31日期间在约旦阿卜杜拉国王大学医院内科服务的所有连续住院患者(n = 5273)。为了识别可避免的再入院,使用了一种被称为SQLape的经过验证的计算机算法。首先采用多项逻辑回归。然后,使用决策树(dt)模型进行详细分析,该模型是临床决策支持系统(CDSS)中最广泛使用的数据挖掘算法之一。结果:潜在可避免的30天再入院率为44%,LOS较长的患者更有可能避免再入院。然而,LOS对不可避免的再入院有显著的负面影响。结论:可避免的再入院率仍然是高度不可接受的。由于LOS可能会增加可避免的再入院的可能性,因此仍有可能在不增加再入院率的情况下实现更短的LOS。此外,DT模型基于患者特征和LOS对再入院患者亚组进行分类的方法适用于实际临床决策。

ABSTRACT Security incidents can have negative impacts on healthcare organizations, and the security of medical records has become a primary concern of the public. However, previous studies showed that organizations had not effectively learned lessons from security incidents. Incident learning as an essential activity in the “follow-up” phase of security incident response lifecycle has long been addressed but not given enough attention. This paper conducted a case study in a healthcare organization in China to explore their current obstacles in the practice of incident learning. We interviewed both IT professionals and healthcare professionals. The results showed that the organization did not have a structured way to gather and redistribute incident knowledge. Incident response was ineffective in cycling incident knowledge back to inform security management. Incident reporting to multiple stakeholders faced a great challenge. In response to this case study, we suggest the security assurance modeling framework to address those obstacles.
安全事件会对医疗机构产生负面影响,医疗记录的安全已成为公众关注的首要问题。然而,先前的研究表明,组织并没有有效地从安全事件中吸取教训。事件学习作为安全事件响应生命周期“后续”阶段的一项重要活动,一直受到关注,但没有得到足够的重视。本文以中国某医疗机构为研究对象,探讨其在事件学习实践中存在的障碍。我们采访了IT专业人员和医疗保健专业人员。结果表明,该组织没有一个结构化的方法来收集和重新分配事件知识。事件响应在将事件知识反馈给安全管理方面是无效的。向多个涉众报告事件面临着巨大的挑战。作为对这个案例研究的回应,我们建议使用安全保证建模框架来解决这些障碍。

ABSTRACT Currently, an estimated 36 million people worldwide are affected by Alzheimer’s disease or related dementias. In the absence of a cure, non-pharmacological interventions, such as cognitive stimulation, which slow down the rate of deterioration can benefit people with dementia and their caregivers. Such interventions have shown to improve well-being and slow down the rate of cognitive decline. It has further been shown that cognitive stimulation in interaction with a computer is as effective as with a human. However, the need to operate a computer often represents a difficulty for the elderly and stands in the way of widespread adoption. A possible solution to this obstacle is to provide a spoken natural language interface that allows people with dementia to interact with the cognitive stimulation software in the same way as they would interact with a human caregiver. This makes the assistive technology accessible to users regardless of their technical skills and provides a fully intuitive user experience. This article describes a pilot study that evaluated the feasibility of computer-based cognitive stimulation through a spoken natural language interface. Prototype software was evaluated with 23 users, including healthy elderly people and people with dementia. Feedback was overwhelmingly positive.
目前,全球约有3600万人受到阿尔茨海默病或相关痴呆的影响。在无法治愈的情况下,认知刺激等减缓恶化速度的非药物干预措施可使痴呆症患者及其护理人员受益。这些干预措施已被证明可以改善幸福感,减缓认知能力下降的速度。研究进一步表明,与电脑互动时的认知刺激与与人互动时一样有效。然而,操作电脑的需要对老年人来说往往是一个困难,并且阻碍了电脑的广泛采用。解决这一障碍的一个可能方法是提供一种自然语言界面,让痴呆症患者与认知刺激软件互动,就像他们与人类护理人员互动一样。这使得无论用户的技术水平如何,都可以使用辅助技术,并提供完全直观的用户体验。本文描述了一项初步研究,该研究评估了通过口头自然语言界面进行基于计算机的认知刺激的可行性。原型软件对23名用户进行了评估,其中包括健康的老年人和痴呆症患者。反馈非常积极。

ABSTRACT Objective: This study adapted an existing computer-delivered brief alcohol intervention (cBAI) for use in Veterans with the hepatitis C virus (HCV) and examined its acceptability and feasibility in this patient population. Methods: A four-stage model consisting of initial pilot testing, qualitative interviews with key stakeholders, development of a beta version of the cBAI, and usability testing was used to achieve the study objectives. Results: In-depth interviews gathered feedback for modifying the cBAI, including adding HCV-related content such as the health effects of alcohol on liver functioning, immune system functioning, and management of HCV, a preference for concepts to be displayed through “newer looking” graphics, and limiting the use of text to convey key concepts. Results from usability testing indicated that the modified cBAI was acceptable and feasible for use in this patient population. Conclusions: The development model used in this study is effective for gathering actionable feedback that can inform the development of a cBAI and can result in the development of an acceptable and feasible intervention for use in this population. Findings also have implications for developing computer-delivered interventions targeting behavior change more broadly.
摘要:目的:本研究将现有的计算机传递的短暂酒精干预(cBAI)用于丙型肝炎病毒(HCV)退伍军人,并检查其在该患者群体中的可接受性和可行性。方法:采用四阶段模型,包括初始试点测试、与关键利益相关者的定性访谈、开发cBAI测试版和可用性测试,以实现研究目标。结果:深入访谈收集了修改cBAI的反馈,包括增加HCV相关内容,如酒精对肝脏功能、免疫系统功能和HCV管理的健康影响,偏好通过“更新”的图形显示概念,以及限制使用文本来传达关键概念。可用性测试的结果表明,改良的cBAI在该患者群体中是可接受和可行的。结论:本研究中使用的发展模型对于收集可操作的反馈是有效的,这些反馈可以为cBAI的发展提供信息,并可以为该人群提供可接受和可行的干预措施。研究结果还对开发针对更广泛行为改变的计算机干预措施具有启示意义。

ABSTRACT Introduction: Text messaging may be an effective method for providing health care reminders to patients. We aimed to understand patient access to and preferences for receiving health-related reminders via text message among patients receiving care in safety-net hospitals. Materials and methods: We conducted face-to-face surveys with 793 patients seeking care in three hospital emergency departments at a large safety-net institution and determined clinical and demographic predictors of preferences for text messaging for health care reminders. Results: 95% of respondents reported having daily access to text messaging. Text messaging was preferred over e-mail, phone, and letters for communication. 78% of respondents wanted to receive appointment reminders, 56% wanted expiring insurance reminders, and 36% wanted reminders to take their medications. We found no clinical predictors but did find some demographic predictors—including age, ethnicity, insurance status, and income—of wanting text message reminders. Discussion: In our convenience sample of safety-net patients, text messaging is an accessible, acceptable, and patient-preferred modality for receiving health care reminders. Text messaging may be a promising patient-centered approach for providing health care and insurance reminders to patients seeking care at safety-net institutions.
摘要简介:短信可能是向患者提供保健提醒的一种有效方法。我们的目的是了解在安全网医院接受治疗的患者通过短信接收健康相关提醒的途径和偏好。材料和方法:我们对在一家大型安全网机构的三家医院急诊科就诊的793名患者进行了面对面的调查,并确定了临床和人口统计学方面的预测因素,即对健康提醒短信的偏好。结果:95%的受访者表示每天都会使用短信。短信比电子邮件、电话和信件更受欢迎。78%的受访者希望收到预约提醒,56%的人希望收到过期保险提醒,36%的人希望收到服药提醒。我们没有发现临床预测因素,但确实发现了一些人口统计学预测因素——包括年龄、种族、保险状况和收入——想要短信提醒。讨论:在我们的方便的安全网患者样本中,短信是一种可访问的、可接受的、患者首选的接收医疗保健提醒的方式。短信可能是一种很有前途的以患者为中心的方法,可以向在安全网机构寻求治疗的患者提供医疗保健和保险提醒。

ABSTRACT Research Interest: In this article, we take an interest in the new kind of relation that has been claimed to be urgently required between health services and patients. Co-production of health services implies fundamental changes in the ways medical care is organized and delivered. Usually, technologies are put forth as potential solutions to problems that might occur when establishing such new relations. Aims: The aim of this study is to scrutinize how different perspectives were brought into the discussions as the concrete design and use of a mobile phone application were introduced, and how participants anticipated and negotiated their own participation in the design project. Methods: This article reports results from an explorative study of a co-design project in hypertension care wherein health professionals and patients were invited to co-design some features of the application they were later to use. Results/Conclusions: The study shows that new practices of self-treatment are not likely to take place without the cooperation of patients, since they are to provide the observational data necessary for the professionals' work. The negotiations are needed to balance patients' concerns of being monitored by technology and their needs of being in control of their everyday lives and activities.
研究兴趣:在这篇文章中,我们采取了一种新的关系,已声称是迫切需要的卫生服务和患者之间的兴趣。保健服务的联合生产意味着医疗保健的组织和提供方式的根本改变。通常,技术是作为建立这种新关系时可能出现的问题的潜在解决方案而提出的。目的:本研究的目的是仔细研究不同的观点是如何被引入讨论的具体设计和手机应用程序的使用,以及参与者如何预期和协商他们自己参与设计项目。方法:本文报告了高血压护理共同设计项目的探索性研究结果,在该项目中,卫生专业人员和患者被邀请共同设计他们以后使用的应用程序的一些功能。结果/结论:研究表明,如果没有患者的配合,新的自我治疗实践是不可能发生的,因为他们是为专业人员的工作提供必要的观察数据。需要进行谈判,以平衡患者对被技术监控的担忧和他们控制自己日常生活和活动的需求。

ABSTRACT Purpose: The aim of the study was to investigate factors that influence the adoption and use of e-Health applications in Bangladesh from citizens’ (patients’) perspectives by extending the technology acceptance model (TAM) to include privacy and trust. Methods: A structured questionnaire survey was used to collect data from more than 350 participants in various private and public hospitals in Dhaka, the capital city of Bangladesh. The data were analyzed using the partial least-squares (PLS) method, a statistical analysis technique based on structural equation modeling (SEM). Results: The study determined that perceived ease of use and perceived usefulness and trust (p < 0.05) were significant factors influencing the intention to adopt e-Health. Privacy (p > 0.05) was identified as a less significant factor in the context of e-Health in Bangladesh. The findings also revealed that gender was strongly associated with the adoption and use of e-Health services. Conclusions: The findings of the present study contribute to the development of strategies and policies to enhance e-Health services in Bangladesh. Furthermore, as a result of the generic approach used in this study, the acceptance model developed can be easily modified to investigate the adoption of e-Health in other developing countries.
摘要目的:本研究的目的是通过扩展技术接受模型(TAM),包括隐私和信任,从公民(患者)的角度调查影响孟加拉国电子健康应用程序采用和使用的因素。方法:采用结构化问卷调查的方法,对孟加拉国首都达卡各私立和公立医院的350多名参与者进行数据收集。数据分析采用偏最小二乘(PLS)方法,这是一种基于结构方程模型(SEM)的统计分析技术。结果:研究发现感知易用性、感知有用性和信任感是影响电子医疗采用意向的显著因素(p < 0.05)。隐私(p > 0.05)被认为是孟加拉国电子卫生背景下的一个不太重要的因素。调查结果还显示,性别与电子保健服务的采用和使用密切相关。结论:本研究的结果有助于制定加强孟加拉国电子保健服务的战略和政策。此外,由于本研究使用的是通用方法,因此可以很容易地修改所开发的接受模型,以调查其他发展中国家采用电子卫生保健的情况。

ABSTRACT Background: A critical issue for multicentre clinical studies is conducting site initiations, ensuring sites are trained in study procedures and comply with relevant governance requirements before they begin recruiting patients. How technology can support site initiations has not previously been explored. Objective: This study sought to evaluate use of off-the-shelf web-based videoconferencing to deliver site initiations for a large national multicentre study. Methods: Participants in the initiations, including podiatrists, diabetologists, trial coordinators, and research nurses, completed an online questionnaire based on the System Usability Scale (SUS) (N = 15). This was followed by semi-structured interviews, with a consultant diabetologist, a trial coordinator, and three research nurses, exploring perceived benefits and limitations of videoconferencing. Results: The mean SUS score for the videoconferencing platform was 87.2 (SD = 13.7), suggesting a good level of usability. Interview participants perceived initiations delivered by videoconferencing as being more interactive and easier to follow than those delivered by teleconference. In comparison to face-to-face initiations, videoconferencing takes less time, easily fitting in with the work of staff at the local sites. Perceptions of impact on communication varied according to the hardware used. Conclusion: Off-the-shelf videoconferencing is a viable alternative to face-to-face site initiations and confers advantages over teleconferencing.
背景:多中心临床研究的一个关键问题是开展站点启动,确保站点在开始招募患者之前接受研究程序培训并遵守相关管理要求。技术如何支持站点初始化还没有被探索过。目的:本研究旨在评估使用现成的基于网络的视频会议来交付大型国家多中心研究的现场启动。方法:包括足科医生、糖尿病医生、试验协调员和研究护士在内的参与者,根据系统可用性量表(SUS)完成一份在线问卷(N = 15)。随后进行了半结构化访谈,与一名糖尿病专家顾问、一名试验协调员和三名研究护士,探讨视频会议的好处和局限性。结果:视频会议平台的SUS平均得分为87.2 (SD = 13.7),可用性较好。受访者认为,与电话会议相比,视频会议提供的入门课程更具互动性,也更容易遵循。与面对面的入门课程相比,视频会议花费的时间更少,很容易适应当地工作人员的工作。对通信影响的看法因所使用的硬件而异。结论:现成的视频会议是面对面现场启动的可行替代方案,并且比电话会议具有优势。

ABSTRACT Background: Frail older adults are high consumers of medical care due to their age and multiple chronic conditions. Regular contact with a case manager has been proven to increase well-being of frail older adults and reduce their number of health-care visits. Skype calls through tablet PCs can offer easier communication. Objective: This paper examines frail older adults’ use of tablet computers and Skype, with their case managers.Method: Interviews were conducted on 15 frail older adults. A content analysis was used to structure and analyze the data. Results: The results indicate that tablet computers were experienced in a positive way for most frail older adults. Conflicting feelings did emerge, however, as to whether the frail elderly would adopt this in the long run. Skype needs to be tested further as to whether this is a good solution for communication with their case managers. Strong technical support and well-functioning technology are important elements to facilitate use. Conclusion: Using Skype and tablet PCs do have potential for frail older adults, but need to be tested further.
背景:年老体弱的老年人由于其年龄和多种慢性疾病,是医疗保健的高消费人群。与病例管理人员的定期接触已被证明可以增加体弱老年人的健康,并减少他们的保健就诊次数。通过平板电脑进行Skype通话可以提供更便捷的沟通。目的:本文探讨体弱老年人使用平板电脑和Skype,与他们的案例管理。方法:对15名体弱老年人进行访谈。内容分析用于构建和分析数据。结果:结果表明,平板电脑对大多数体弱的老年人来说是一种积极的体验。然而,对于体弱多病的老年人是否会长期采用这种方法,矛盾的感觉确实出现了。Skype需要进一步测试,以确定这是否是一个与他们的案例管理人员沟通的好解决方案。强有力的技术支持和功能良好的技术是促进使用的重要因素。结论:使用Skype和平板电脑对虚弱的老年人确实有潜在的影响,但需要进一步的测试。
