    背景:种族主义和内隐偏见是医疗保健获取方面差异的基础,治疗,和结果。检查健康差异的一个新兴研究领域是在电子健康记录(EHR)中使用污名化语言。
    目的:我们试图总结EHR中记录的与污名化语言相关的现有文献。为此,我们进行了范围审查以确定,描述,并评估与污名化语言和临床医生笔记相关的现有文献。
    方法:我们搜索了PubMed,护理和相关健康文献累积指数(CINAHL),和Embase数据库在2022年5月,还对IEEE进行了手工搜索,以确定研究临床文档中污名化语言的研究。我们纳入了截至2022年4月发表的所有研究。每次搜索的结果都上传到EndNoteX9软件中,使用Bramer方法去重复,然后导出到Covidence软件进行标题和摘要筛选。
    结果:研究(N=9)使用横截面(n=3),定性(n=3),混合方法(n=2),和回顾性队列(n=1)设计。污名化语言是通过临床文件的内容分析来定义的(n=4),文献综述(n=2),与临床医生(n=3)和患者(n=1)的访谈,专家小组咨询,和工作队指导方针(n=1)。在四项研究中使用自然语言处理来从临床笔记中识别和提取污名化的单词。审查的所有研究都得出结论,消极的临床医生态度和在文档中使用污名化语言可能会对患者对护理或健康结果的看法产生负面影响。
    结论:目前的文献表明,NLP是一种新兴的方法来识别EHR中记录的污名化语言。可以开发基于NLP的解决方案并将其集成到常规文档系统中,以筛选污名化的语言并提醒临床医生或其主管。这项研究产生的潜在干预措施可以使人们意识到内隐偏见如何影响沟通模式,并努力为不同人群实现公平的医疗保健。
    BACKGROUND: Racism and implicit bias underlie disparities in health care access, treatment, and outcomes. An emerging area of study in examining health disparities is the use of stigmatizing language in the electronic health record (EHR).
    OBJECTIVE: We sought to summarize the existing literature related to stigmatizing language documented in the EHR. To this end, we conducted a scoping review to identify, describe, and evaluate the current body of literature related to stigmatizing language and clinician notes.
    METHODS: We searched PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), and Embase databases in May 2022, and also conducted a hand search of IEEE to identify studies investigating stigmatizing language in clinical documentation. We included all studies published through April 2022. The results for each search were uploaded into EndNote X9 software, de-duplicated using the Bramer method, and then exported to Covidence software for title and abstract screening.
    RESULTS: Studies (N = 9) used cross-sectional (n = 3), qualitative (n = 3), mixed methods (n = 2), and retrospective cohort (n = 1) designs. Stigmatizing language was defined via content analysis of clinical documentation (n = 4), literature review (n = 2), interviews with clinicians (n = 3) and patients (n = 1), expert panel consultation, and task force guidelines (n = 1). Natural language processing was used in four studies to identify and extract stigmatizing words from clinical notes. All of the studies reviewed concluded that negative clinician attitudes and the use of stigmatizing language in documentation could negatively impact patient perception of care or health outcomes.
    CONCLUSIONS: The current literature indicates that NLP is an emerging approach to identifying stigmatizing language documented in the EHR. NLP-based solutions can be developed and integrated into routine documentation systems to screen for stigmatizing language and alert clinicians or their supervisors. Potential interventions resulting from this research could generate awareness about how implicit biases affect communication patterns and work to achieve equitable health care for diverse populations.

    背景:电子健康记录(EHR)代表了患者病史的综合资源。EHR对于利用深度学习(DL)等先进技术至关重要,使医疗保健提供商能够分析大量数据,提取有价值的见解,并做出精确和数据驱动的临床决策。诸如递归神经网络(RNN)的DL方法已被用于分析EHR以对疾病进展建模和预测诊断。然而,这些方法不能解决EHR数据中一些固有的不规则性,例如临床就诊之间的不规则时间间隔.此外,大多数DL模型是不可解释的。在这项研究中,我们提出了两种基于RNN的可解释DL架构,即时间感知RNN(TA-RNN)和TA-RNN自动编码器(TA-RNN-AE),用于预测患者在下一次就诊和多次就诊时的EHR临床结果,分别。为了减轻不规则时间间隔的影响,我们建议纳入访问之间经过时间的时间嵌入。为了可解释性,我们建议采用双层关注机制,在每次访问和功能之间运作。
    结果:在阿尔茨海默病神经影像学计划(ADNI)和国家阿尔茨海默病协调中心(NACC)数据集上进行的实验结果表明,与基于F2和敏感性的最新技术和基线方法相比,所提出的用于预测阿尔茨海默病(AD)的模型具有出色的性能。此外,TA-RNN在重症监护医学信息集市(MIMIC-III)数据集上显示出优异的死亡率预测性能。在我们的消融研究中,我们观察到通过结合时间嵌入和注意力机制来增强预测性能。最后,调查注意力权重有助于在预测中识别有影响力的访问和特征。

    BACKGROUND: Electronic health records (EHRs) represent a comprehensive resource of a patient\'s medical history. EHRs are essential for utilizing advanced technologies such as deep learning (DL), enabling healthcare providers to analyze extensive data, extract valuable insights, and make precise and data-driven clinical decisions. DL methods such as recurrent neural networks (RNN) have been utilized to analyze EHR to model disease progression and predict diagnosis. However, these methods do not address some inherent irregularities in EHR data such as irregular time intervals between clinical visits. Furthermore, most DL models are not interpretable. In this study, we propose two interpretable DL architectures based on RNN, namely time-aware RNN (TA-RNN) and TA-RNN-autoencoder (TA-RNN-AE) to predict patient\'s clinical outcome in EHR at the next visit and multiple visits ahead, respectively. To mitigate the impact of irregular time intervals, we propose incorporating time embedding of the elapsed times between visits. For interpretability, we propose employing a dual-level attention mechanism that operates between visits and features within each visit.
    RESULTS: The results of the experiments conducted on Alzheimer\'s Disease Neuroimaging Initiative (ADNI) and National Alzheimer\'s Coordinating Center (NACC) datasets indicated the superior performance of proposed models for predicting Alzheimer\'s Disease (AD) compared to state-of-the-art and baseline approaches based on F2 and sensitivity. Additionally, TA-RNN showed superior performance on the Medical Information Mart for Intensive Care (MIMIC-III) dataset for mortality prediction. In our ablation study, we observed enhanced predictive performance by incorporating time embedding and attention mechanisms. Finally, investigating attention weights helped identify influential visits and features in predictions.

    对广泛的电子健康记录(EHR)数据集的分析通常需要自动化解决方案,使用机器学习(ML)技术,包括深度学习(DL),扮演主角。一个常见的任务涉及将EHR数据分类为预定义的组。然而,EHR对数据收集过程中产生的噪声和错误的脆弱性,以及潜在的人为标签错误,构成重大风险。这种风险在DL模型的训练过程中尤为突出,过度适应嘈杂标签的可能性可能会在医疗保健中产生严重影响。尽管EHR数据中存在有据可查的标签噪声,很少有研究在EHR领域内解决这一挑战。我们的工作通过调整计算机视觉(CV)算法来解决这一差距,以减轻在EHR数据上训练的DL模型中标签噪声的影响。值得注意的是,尚不确定CV方法是否,当应用于EHR域时,将证明是有效的,考虑到两个域之间的巨大差异。我们提供的经验证据表明,这些方法,无论是单独使用还是组合使用,当应用于EHR数据时,可以大大提高模型性能,特别是在存在嘈杂/不正确的标签的情况下。我们验证了我们的方法,并强调了它们在现实世界EHR数据中的实际效用,特别是在COVID-19诊断的背景下。我们的研究强调了CV方法在EHR领域的有效性,为医疗保健分析和研究的发展做出了宝贵的贡献。
    The analysis of extensive electronic health records (EHR) datasets often calls for automated solutions, with machine learning (ML) techniques, including deep learning (DL), taking a lead role. One common task involves categorizing EHR data into predefined groups. However, the vulnerability of EHRs to noise and errors stemming from data collection processes, as well as potential human labeling errors, poses a significant risk. This risk is particularly prominent during the training of DL models, where the possibility of overfitting to noisy labels can have serious repercussions in healthcare. Despite the well-documented existence of label noise in EHR data, few studies have tackled this challenge within the EHR domain. Our work addresses this gap by adapting computer vision (CV) algorithms to mitigate the impact of label noise in DL models trained on EHR data. Notably, it remains uncertain whether CV methods, when applied to the EHR domain, will prove effective, given the substantial divergence between the two domains. We present empirical evidence demonstrating that these methods, whether used individually or in combination, can substantially enhance model performance when applied to EHR data, especially in the presence of noisy/incorrect labels. We validate our methods and underscore their practical utility in real-world EHR data, specifically in the context of COVID-19 diagnosis. Our study highlights the effectiveness of CV methods in the EHR domain, making a valuable contribution to the advancement of healthcare analytics and research.

    连续肾脏替代疗法(CRRT)是一种针对无法耐受常规血液透析的重症患者的透析形式。然而,因为病人一开始通常病得很重,他们在CRRT治疗期间或之后是否会存活总是存在不确定性.由于结果的不确定性,大部分接受CRRT治疗的患者无法生存,利用稀缺资源,提高患者及其家人的虚假希望。为了解决这些问题,我们提出了一种基于机器学习的算法来预测接受CRRT的患者的短期生存率.我们使用从多个机构接受CRRT的患者的电子健康记录中提取的信息来训练预测CRRT生存结果的模型;在保留的测试集上,该模型的接收器工作曲线下面积为0.848(CI=0.822-0.870)。特征重要性,错误,子群分析为模型预测提供了对偏差和相关特征的洞察。总的来说,我们展示了预测机器学习模型的潜力,以帮助临床医生减轻CRRT患者生存结果的不确定性,通过进一步的数据收集和高级建模,有机会进行未来的改进。
    Continuous renal replacement therapy (CRRT) is a form of dialysis prescribed to severely ill patients who cannot tolerate regular hemodialysis. However, as the patients are typically very ill to begin with, there is always uncertainty whether they will survive during or after CRRT treatment. Because of outcome uncertainty, a large percentage of patients treated with CRRT do not survive, utilizing scarce resources and raising false hope in patients and their families. To address these issues, we present a machine learning-based algorithm to predict short-term survival in patients being initiated on CRRT. We use information extracted from electronic health records from patients who were placed on CRRT at multiple institutions to train a model that predicts CRRT survival outcome; on a held-out test set, the model achieves an area under the receiver operating curve of 0.848 (CI = 0.822-0.870). Feature importance, error, and subgroup analyses provide insight into bias and relevant features for model prediction. Overall, we demonstrate the potential for predictive machine learning models to assist clinicians in alleviating the uncertainty of CRRT patient survival outcomes, with opportunities for future improvement through further data collection and advanced modeling.

    美国医疗保健提供系统没有系统地参与或支持家人或朋友护理伙伴。同时,患者对个人健康信息门户的吸收和熟悉程度正在增加。技术创新,例如对门户的共享访问,使用单独的身份凭证来区分患者和护理伙伴.虽然不是众所周知的,或常用的,共享访问允许患者识别他们做了谁,不想参与他们的护理。然而,患者授予对门户的共享访问权限的过程通常是有限的或繁重的,以至于感兴趣的患者和护理伙伴通常会完全绕过该过程。因此,绝大多数护理合作伙伴诉诸于使用患者身份凭证访问门户-“自己动手”解决方案与卫生系统的法律责任相冲突,以保护患者的隐私和自主权。这种观点的个人叙述(通过许可共享)详细阐述了定量研究,并提供了患者和家庭在他们生命中关键时刻试图获得或授予共享访问权限时所面临的挑战的第一人称快照。随着数字模式增加患者在医疗保健互动中的角色,为所有利益相关者-患者-进行共享访问的重要性也是如此,临床医生,和护理伙伴。电子健康记录供应商必须认识到,患者和护理合作伙伴都是其产品的重要用户,和卫生保健组织必须承认和支持的关键贡献的护理合作伙伴不同于患者。
    The US health care delivery system does not systematically engage or support family or friend care partners. Meanwhile, the uptake and familiarity of portals to personal health information are increasing among patients. Technology innovations, such as shared access to the portal, use separate identity credentials to differentiate between patients and care partners. Although not well-known, or commonly used, shared access allows patients to identify who they do and do not want to be involved in their care. However, the processes for patients to grant shared access to portals are often limited or so onerous that interested patients and care partners often circumvent the process entirely. As a result, the vast majority of care partners resort to accessing portals using a patient\'s identity credentials-a \"do-it-yourself\" solution in conflict with a health systems\' legal responsibility to protect patient privacy and autonomy. The personal narratives in this viewpoint (shared by permission) elaborate on quantitative studies and provide first-person snapshots of challenges faced by patients and families as they attempt to gain or grant shared access during crucial moments in their lives. As digital modalities increase patient roles in health care interactions, so does the importance of making shared access work for all stakeholders involved-patients, clinicians, and care partners. Electronic health record vendors must recognize that both patients and care partners are important users of their products, and health care organizations must acknowledge and support the critical contributions of care partners as distinct from patients.

    医疗保健正处于一个转折点。我们正在从原始医学转向精准医学,数字医疗系统正在促进这一转变。通过为临床医生提供每位患者的详细信息以及在护理点为决策提供分析支持,数字健康技术正在开启精准医疗的新时代。基因组数据还为临床医生提供了可以提高诊断准确性和及时性的信息,优化处方,和目标风险降低策略,所有这些都是精准医疗的关键要素。然而,基因组数据主要被视为诊断信息,没有被常规地整合到电子病历的临床工作流程中.基因组数据的使用具有精确医学的巨大潜力;然而,由于基因组数据与常规实践中收集的信息根本不同,在数字健康环境中使用此信息需要特别考虑。本文概述了基因组数据与电子记录整合的潜力,以及这些数据如何实现精准医疗。
    Health care is at a turning point. We are shifting from protocolized medicine to precision medicine, and digital health systems are facilitating this shift. By providing clinicians with detailed information for each patient and analytic support for decision-making at the point of care, digital health technologies are enabling a new era of precision medicine. Genomic data also provide clinicians with information that can improve the accuracy and timeliness of diagnosis, optimize prescribing, and target risk reduction strategies, all of which are key elements for precision medicine. However, genomic data are predominantly seen as diagnostic information and are not routinely integrated into the clinical workflows of electronic medical records. The use of genomic data holds significant potential for precision medicine; however, as genomic data are fundamentally different from the information collected during routine practice, special considerations are needed to use this information in a digital health setting. This paper outlines the potential of genomic data integration with electronic records, and how these data can enable precision medicine.

    目的:电子健康记录(EHR)的不断扩大,突显了提高互操作性的必要性。为了测试肿瘤学研究领域内的互操作性,我们在范德比尔特大学医学中心(VUMC)的团队使我们基于Epic的EHR与最小常见肿瘤学数据元素(mCODE)兼容,这是一个基于快速医疗互操作性资源(FHIR)的共识数据标准,旨在促进癌症患者的EHR传输。
    方法:我们的方法使用了摘录,变换,加载工具,用于将VUMCEpicClarity数据库中的EHR数据转换为与mCODE兼容的配置文件。我们在MicrosoftAzure上建立了一个用于数据迁移的沙盒环境,部署了FHIR服务器来处理应用程序编程接口(API)请求,并映射VUMC数据以与mCODE结构对齐。此外,我们构建了一个Web应用程序来演示mCODE配置文件在医疗保健中的实际使用。
    结果:我们开发了一个端到端管道,将EHR数据转换为符合mCODE的配置文件,以及可视化基因组数据并提供癌症风险评估的Web应用程序。尽管将传统EHR数据库与mCODE标准保持一致的复杂性以及FHIRAPI在支持高级统计方法方面的局限性,该项目成功地展示了mCODE标准与现有医疗保健基础设施的实际整合。
    结论:这项研究为主要医疗保健机构的EHR系统中mCODE的互操作性提供了概念证明,强调了FHIRAPI在支持肿瘤学研究的复杂数据分析方面的潜力和当前局限性。
    OBJECTIVE: The expanding presence of the electronic health record (EHR) underscores the necessity for improved interoperability. To test the interoperability within the field of oncology research, our team at Vanderbilt University Medical Center (VUMC) enabled our Epic-based EHR to be compatible with the Minimal Common Oncology Data Elements (mCODE), which is a Fast Healthcare Interoperability Resources (FHIR)-based consensus data standard created to facilitate the transmission of EHRs for patients with cancer.
    METHODS: Our approach used an extract, transform, load tool for converting EHR data from the VUMC Epic Clarity database into mCODE-compatible profiles. We established a sandbox environment on Microsoft Azure for data migration, deployed a FHIR server to handle application programming interface (API) requests, and mapped VUMC data to align with mCODE structures. In addition, we constructed a web application to demonstrate the practical use of mCODE profiles in health care.
    RESULTS: We developed an end-to-end pipeline that converted EHR data into mCODE-compliant profiles, as well as a web application that visualizes genomic data and provides cancer risk assessments. Despite the complexities of aligning traditional EHR databases with mCODE standards and the limitations of FHIR APIs in supporting advanced statistical methodologies, this project successfully demonstrates the practical integration of mCODE standards into existing health care infrastructures.
    CONCLUSIONS: This study provides a proof of concept for the interoperability of mCODE within a major health care institution\'s EHR system, highlighting both the potential and the current limitations of FHIR APIs in supporting complex data analysis for oncology research.

    目的:开发一种多模式学习应用系统,该系统集成了电子病历(EMR)和宫腔镜图像,用于子宫内膜损伤导致的宫腔粘连(IUA)患者的生殖结局预测和风险分层。
    方法:从我们建立的多中心IUA数据库中,对753例宫腔镜粘连松解术后患者的EMR和5014再次观察宫腔镜图像进行了随机分配,验证,和测试数据集。各自的数据集用于模型开发,调谐,和多模态学习应用程序的测试。MobilenetV3用于图像特征提取,和XGBoost用于EMR和图像特征集成学习。将应用程序的性能与单模态方法(EMR或宫腔镜图像)进行比较,DeepSurv和ElasticNet模型,以及临床评分系统。主要结果是1年受孕预测的准确性,次要结局是风险分层后的辅助生殖技术(ART)获益比.
    结果:多模式学习系统在1年内预测受孕方面表现出优异的性能,曲线下面积为0.967(95%CI:0.950-0.985),0.936(95%CI:0.883-0.989),和0.965(95%CI:0.935-0.994)在训练中,验证,和测试数据集,分别,超越单模态方法,其他模型和临床评分系统(均P<0.05)。该模型的应用在宫腔镜平台上无缝运行,平均分析时间为每名患者3.7±0.8s。通过采用应用程序的概念基于概率的风险分层,中高危患者显示出显著的ART获益(比值比=6,95%CI:1.27-27.8,P=0.02),而低风险患者表现出良好的自然受孕潜力,ART治疗的受胎率没有显着增加(P=1)。
    结论:使用宫腔镜图像和EMR的多模式学习系统在准确预测IUA患者的自然受孕并提供有效的术后分层方面显示出希望。可能有助于IUA手术后的ART分诊。
    OBJECTIVE: To develop a multimodal learning application system that integrates electronic medical records (EMR) and hysteroscopic images for reproductive outcome prediction and risk stratification of patients with intrauterine adhesions (IUAs) resulting from endometrial injuries.
    METHODS: EMR and 5014 revisited hysteroscopic images of 753 post hysteroscopic adhesiolysis patients from the multicenter IUA database we established were randomly allocated to training, validation, and test datasets. The respective datasets were used for model development, tuning, and testing of the multimodal learning application. MobilenetV3 was employed for image feature extraction, and XGBoost for EMR and image feature ensemble learning. The performance of the application was compared against the single-modal approaches (EMR or hysteroscopic images), DeepSurv and ElasticNet models, along with the clinical scoring systems. The primary outcome was the 1-year conception prediction accuracy, and the secondary outcome was the assisted reproductive technology (ART) benefit ratio after risk stratification.
    RESULTS: The multimodal learning system exhibited superior performance in predicting conception within 1-year, achieving areas under the curves of 0.967 (95% CI: 0.950-0.985), 0.936 (95% CI: 0.883-0.989), and 0.965 (95% CI: 0.935-0.994) in the training, validation, and test datasets, respectively, surpassing single-modal approaches, other models and clinical scoring systems (all P<0.05). The application of the model operated seamlessly on the hysteroscopic platform, with an average analysis time of 3.7±0.8 s per patient. By employing the application\'s conception probability-based risk stratification, mid-high-risk patients demonstrated a significant ART benefit (odds ratio=6, 95% CI: 1.27-27.8, P=0.02), while low-risk patients exhibited good natural conception potential, with no significant increase in conception rates from ART treatment (P=1).
    CONCLUSIONS: The multimodal learning system using hysteroscopic images and EMR demonstrates promise in accurately predicting the natural conception of patients with IUAs and providing effective postoperative stratification, potentially contributing to ART triage after IUA procedures.
