    人工智能(AI)在移动健康(mHealth)中的日益突出已经产生了一个不同的应用程序子集,这些应用程序使用用户输入的健康状况和症状信息为用户提供诊断信息-AI支持的症状检查器应用程序(AIShycheck)。虽然这些应用程序可能会增加获得医疗保健的机会,他们提出了相应的道德和法律问题。本文将强调人工智能在医疗保健系统中的使用值得注意的问题,进一步巩固医疗保健系统中现有的偏见和专业问责制问题。对专业义务和责任的偏见和复杂性问题进行深入分析,我们专注于2mHealth应用程序作为例子-巴比伦和阿达。我们选择了这两个应用程序,因为它们在COVID-19大流行期间都广泛分发,并对它们使用人工智能来评估用户症状做出了突出的声明。首先,偏见根深蒂固通常源于用于训练人工智能系统的数据,让人工智能通过垃圾复制这些不平等,“垃圾出”现象。这些应用程序的用户也不太可能在人口统计上代表更大的人口,导致扭曲的结果。第二,鉴于AISymCheck应用程序可靠性的巨大多样性和缺乏监管,专业问责制构成了重大挑战。目前还不清楚这些应用程序是否应该接受安全审查。负责应用介导的误诊,以及这些应用程序是否应该由医生推荐。随着应用程序数量的迅速增加,对卫生专业人员的指导仍然很少。专业机构和宣传组织在解决这些道德和法律差距方面可以发挥特别重要的作用。在这些应用程序中实施技术保障措施可以减轻偏见,人工智能可以主要用中性数据进行训练,应用程序可能会受到监管系统的约束,以允许用户做出明智的决定。在我们看来,至关重要的是,在这些潜在破坏性技术的设计和实施过程中,必须考虑这些法律问题。根深蒂固的偏见和职业责任,在以不同方式操作时,最终加剧了mHealth的不受管制的性质。
    The growing prominence of artificial intelligence (AI) in mobile health (mHealth) has given rise to a distinct subset of apps that provide users with diagnostic information using their inputted health status and symptom information-AI-powered symptom checker apps (AISympCheck). While these apps may potentially increase access to health care, they raise consequential ethical and legal questions. This paper will highlight notable concerns with AI usage in the health care system, further entrenchment of preexisting biases in the health care system and issues with professional accountability. To provide an in-depth analysis of the issues of bias and complications of professional obligations and liability, we focus on 2 mHealth apps as examples-Babylon and Ada. We selected these 2 apps as they were both widely distributed during the COVID-19 pandemic and make prominent claims about their use of AI for the purpose of assessing user symptoms. First, bias entrenchment often originates from the data used to train AI systems, causing the AI to replicate these inequalities through a \"garbage in, garbage out\" phenomenon. Users of these apps are also unlikely to be demographically representative of the larger population, leading to distorted results. Second, professional accountability poses a substantial challenge given the vast diversity and lack of regulation surrounding the reliability of AISympCheck apps. It is unclear whether these apps should be subject to safety reviews, who is responsible for app-mediated misdiagnosis, and whether these apps ought to be recommended by physicians. With the rapidly increasing number of apps, there remains little guidance available for health professionals. Professional bodies and advocacy organizations have a particularly important role to play in addressing these ethical and legal gaps. Implementing technical safeguards within these apps could mitigate bias, AIs could be trained with primarily neutral data, and apps could be subject to a system of regulation to allow users to make informed decisions. In our view, it is critical that these legal concerns are considered throughout the design and implementation of these potentially disruptive technologies. Entrenched bias and professional responsibility, while operating in different ways, are ultimately exacerbated by the unregulated nature of mHealth.

    目前,女性约占全球医护人员的70%。占全球牙科劳动力的60.9%,77.6%的美国医疗劳动力和36.7%的美国牙科劳动力。美国牙科协会指出,自2001年以来,美国执业女性牙医的数量增加了2.25倍,预计到2040年将趋于平稳。尽管对全球医疗保健行业产生了重大影响,女性的收入比男性低24%,只在25%的高级领导职位上任职。在美国牙科学校,只有14%的教师担任行政职务,截至2022年4月,28.6%的美国牙科学校院长是女性,表明在学术领导的最高角色中性别代表性不足。这与许多社会和工作场所仍然不规范的性别均等数据相对应,可以归因于公共政策,刻板印象,和个人因素。已经确定了五个关键因素对于妇女进入或提高全球卫生领导地位至关重要:a)公共政策,b)社区,c)机构,D)人际关系,和e)个人。个人自我完善和制度实践可以用来克服这些障碍,妇女在医疗保健方面的领导地位,并将权力动力转向加强性别平等。这些变革性的变化是通过女性的集体能力和技能来衡量的,关系动态,社区认知,和环境实践。本文认识到目前妇女在医疗保健领导方面的障碍,并提出了通过个人和机构实践实现性别平等的策略。
    Women currently represent approximately 70% of the global healthcare workforce, 60.9% of the global dental workforce, 77.6% of the US healthcare workforce, and 36.7% of the US dental workforce. The American Dental Association states that the number of practicing women dentists in the United States has increased by 2.25 times since 2001, with a projected trajectory to level off by 2040. Despite having a major impact on the healthcare sector globally, women earn 24% less than men and only serve in 25% of senior leadership positions. In the US dental schools, only 14% of faculty serve in administrative roles, and as of April 2022, 28.6% of the US dental school deans were women, indicating gender underrepresentation in the highest roles of academic leadership. This corresponds to the data on gender parity still not being the norm in many societies and workplaces and can be attributed to public policies, stereotypical perceptions, and individual factors. Five key factors have been identified to be crucial for women\'s entry or advancement in global health leadership: a) public policy, b) community, c) institutional, d) interpersonal, and e) individual. Individual self-improvement and institutional practices may be used to overcome these barriers to women\'s leadership in healthcare and shift the power dynamics toward reinforcing gender equality. These transformative changes are measured through women\'s collective capacities and skills, relationship dynamics, community perceptions, and environmental practices. This article recognizes the present obstacles to women in healthcare leadership and proposes strategies to achieve gender equality both through individual and institutional practices.

    疼痛护理方面的差异是有据可查的,因此与男性和白人相比,女性和有色人种的疼痛受到了低估和低估。对有色人种和女性疼痛治疗不足的原因之一可能是对疼痛的不准确评估。了解疼痛评估过程是评估护理中疼痛差异程度和干预疼痛差异的重要一步。在目前的工作中,我们专注于记录疼痛评估中的交叉种族和性别偏见,并介绍了减少这些偏见的新型干预措施的结果。在三项研究(N=532)和使用真实录像的人在疼痛作为刺激的迷你荟萃分析中,我们证明,与所有其他群体相比,观察者不成比例地低估了有色人种女性的痛苦(有色人种,白人女性,和白人)。在研究3(N=232)中,我们证明了一种专注于行为技能建设的新颖干预(即,实践和即时反馈)与所有其他类型的培训相比,显著减少了观察者对边缘化群体的疼痛评估偏见(提高对社会偏见的认识,提高自我偏见的意识,和控制条件)。虽然这种干预持续多长时间是一个悬而未决的问题,围绕更准确地评估边缘化人群的疼痛而构建的行为技能是医疗保健专业人员的一个有前途的培训工具。观点:这篇文章展示了有色人种和女性对痛苦的低估。我们还发现,新的干预措施减少了观察者对边缘化群体的疼痛评估偏见。这可以用于医学教育或临床护理,以减少交叉疼痛护理差异。
    Disparities in pain care are well-documented such that women and people of color have their pain undertreated and underestimated compared to men and White people. One of the contributors of the undertreatment of pain for people of color and women may be the inaccurate assessment of pain. Understanding the pain assessment process is an important step in evaluating the magnitude of and intervening on pain disparities in care. In the current work, we focus on documenting intersectional race and gender biases in pain assessment and present the results of a novel intervention for reducing these biases. Across 3 studies (N = 532) and a mini meta-analysis using real videotaped people in pain as stimuli, we demonstrate that observers disproportionately underestimated women of color\'s pain compared to all other groups (men of color, White women, and White men). In study 3 (N = 232), we show that a novel intervention focused on behavioral skill building (ie, practice and immediate feedback) significantly reduced observers\' pain assessment biases toward marginalized groups compared to all other types of trainings (raising awareness of societal biases, raising awareness of self-biases, and a control condition). While it is an open question as to how long this type of intervention lasts, behavioral skills building around assessing marginalized people\'s pain more accurately is a promising training tool for health care professionals. PERSPECTIVE: This article demonstrates the underestimation of pain among people of color and women. We also found support that a novel intervention reduced observers\' pain assessment biases toward marginalized groups. This could be used in medical education or clinical care to reduce intersectional pain care disparities.

    所有个人和团体都有盲点,如果不解决,可能会产生问题。这项研究的目的是从国际角度研究医学教育中的盲点。
    从2022年12月到2023年3月,我们通过国际医学生网络分发了一项电子调查,研究生学员,和医学教育工作者。受访者命名了影响其医学教育系统的盲点,然后根据5点Likert型量表对美国医学教育研究中的9个盲点领域进行了评分(1=需要更少的关注;5=需要更多的关注)。我们测试了受访者群体盲点评分之间的差异。我们还分析了受访者确定的盲点,以确定先前未描述的盲点,并对有关盲点域的开放式响应进行了内容分析。
    来自88个国家的356名受访者,包括127名(44%)教育工作者,80名(28%)医学生,和33名(11%)研究生学员。至少有80%的受访者认为每个盲点领域都需要“更多”或“更多”关注;最高的是88%的患者观点和未听到的声音,估值,或理解。在按性别进行的分析中,在医学教育中的作用,世界银行国家收入水平,和区域,在279项可能的统计学比较中,仅有5项的平均差为0.5.记录了885个盲点,与跨国界问题(例如国际标准)和支持医学教育的资源充足有关的新盲点领域。关于九个盲点领域的评论说明了文化,卫生系统,政府因素影响了盲点在不同环境中的表现。
    关于医学教育中的盲点,全世界可能会达成普遍共识,值得更多关注。这可以为协调国际努力分配资源和调整干预措施以促进医学教育奠定基础。
    UNASSIGNED: All individuals and groups have blind spots that can create problems if unaddressed. The goal of this study was to examine blind spots in medical education from international perspectives.
    UNASSIGNED: From December 2022 to March 2023, we distributed an electronic survey through international networks of medical students, postgraduate trainees, and medical educators. Respondents named blind spots affecting their medical education system and then rated nine blind spot domains from a study of U.S. medical education along five-point Likert-type scales (1 = much less attention needed; 5 = much more attention needed). We tested for differences between blind spot ratings by respondent groups. We also analyzed the blind spots that respondents identified to determine those not previously described and performed content analysis on open-ended responses about blind spot domains.
    UNASSIGNED: There were 356 respondents from 88 countries, including 127 (44%) educators, 80 (28%) medical students, and 33 (11%) postgraduate trainees. At least 80% of respondents rated each blind spot domain as needing \'more\' or \'much more\' attention; the highest was 88% for \'Patient perspectives and voices that are not heard, valued, or understood.\' In analyses by gender, role in medical education, World Bank country income level, and region, a mean difference of 0.5 was seen in only five of the possible 279 statistical comparisons. Of 885 blind spots documented, new blind spot areas related to issues that crossed national boundaries (e.g. international standards) and the sufficiency of resources to support medical education. Comments about the nine blind spot domains illustrated that cultural, health system, and governmental elements influenced how blind spots are manifested across different settings.
    UNASSIGNED: There may be general agreement throughout the world about blind spots in medical education that deserve more attention. This could establish a basis for coordinated international effort to allocate resources and tailor interventions that advance medical education.

    研究群体间偏见的科学家通常关注减少歧视(一个社会群体与另一个社会群体的不平等待遇),但是许多减少这种偏见行为的干预措施证据薄弱或有限。在这篇评论文章中,我们认为,减少歧视的一个有效途径来自于在一个单独的领域——判断和决策——中调整干预措施,这在历史上研究了“去偏见”:人们可以减轻无关信息对决策的不必要影响的方式。虽然去偏见研究与减少群体间歧视的研究有几个共同点,许多消除偏见的干预措施依赖于不同于群间偏见文献中使用的方法.我们回顾了几个实例,这些实例已成功应用了消除偏见原则来减少行为上的群体间偏见,并引入了其他可能非常适合未来减少歧视的消除偏见技术。
    UNASSIGNED: Scientists studying intergroup biases are often concerned with lessening discrimination (unequal treatment of one social group versus another), but many interventions for reducing such biased behavior have weak or limited evidence. In this review article, we argue one productive avenue for reducing discrimination comes from adapting interventions in a separate field-judgment and decision-making-that has historically studied \"debiasing\": the ways people can lessen the unwanted influence of irrelevant information on decision-making. While debiasing research shares several commonalities with research on reducing intergroup discrimination, many debiasing interventions have relied on methods that differ from those deployed in the intergroup bias literature. We review several instances where debiasing principles have been successfully applied toward reducing intergroup biases in behavior and introduce other debiasing techniques that may be well-suited for future efforts in lessening discrimination.

    BACKGROUND: Family reconstitution and data from online genealogies, such as FamiLinx, are two potential sources for investigating mortality dynamics for the period before official lifetables became available. In this paper, we use two of them, the family reconstitution of Imhof and the FamiLinx dataset based on geni.com, to estimate dynamics in life expectancy and discuss the sex-specific differential mortality in the German Empire.
    METHODS: Sex-specific lifetables are estimated for the territory of the German Empire from the individual data of the family reconstitution and the online genealogies. On the basis of these lifetables, we estimate the conditional life expectancy and derive the corresponding sex-specific differential mortality. Findings are compared with the official lifetable of the German Empire in 1871-1910. The contribution of each age group to the differential mortality is determined using the stepwise-replacement algorithm.
    RESULTS: The family reconstitution overestimates conditional life expectancy less than FamiLinx after 1871, when official lifetables are available in the German Empire. However, both sources fail to capture the sex-specific mortality differentials of the official lifetables at the end of the nineteenth century and show a higher life expectancy for males instead of females. The bias in sex-specific mortality rates is particularly pronounced in the age groups 15 to 45.
    CONCLUSIONS: Finally, we discuss possible explanations for the biased findings. Notability bias, the patriarchal approach to family trees, and maternal mortality are important mechanisms in the FamiLinx dataset. Censoring due to mobility serves as a potential reason for the bias in the family reconstitution.
    UNASSIGNED: HINTERGRUND: Familienrekonstitutionen und Familienstammbäume genealogischer Online-Plattformen sind 2 mögliche Datenquellen für die Untersuchung der Sterblichkeit in einer Zeit, als noch keine amtlichen Sterbetafeln verfügbar waren. Der vorliegende Artikel diskutiert anhand zweier Beispiele, der Familienrekonstitution aus Imhof und dem auf geni.com beruhenden Datensatz FamiLinx, die geschätzten Verläufe der Lebenserwartung im Deutschen Reich mit einem Fokus auf die geschlechtsspezifische differenzielle Mortalität.
    METHODS: Mithilfe der Individualdaten aus der Familienrekonstitution und aus den Online-Genealogien werden die geschlechtsspezifischen Sterbetafeln geschätzt. Aus ihnen wird die bedingte Lebenserwartung ermittelt und die entsprechende geschlechtsspezifische differenzielle Mortalität abgeleitet und mit den amtlichen Sterbetafeln für die Jahre 1871–1910 abgeglichen. Der Beitrag der einzelnen Altersklassen zur differenziellen Sterblichkeit wird mit dem Stepwise Replacement Algorithm bestimmt.
    UNASSIGNED: Die Ergebnisse der Familienrekonstitution überschätzen die Lebenserwartung nach 1871 weniger stark als die FamiLinx-Schätzungen. Die geringere Sterblichkeit der Frauen in der amtlichen Statistik wird von beiden Quellen nicht abgebildet. Im Gegensatz zur amtlichen Statistik ist die geschätzte Lebenserwartung der Männer höher als die der Frauen. Diese verzerrte geschlechtsspezifische Abbildung der Mortalitätsraten geht insbesondere auf die Altersklassen von 15 bis 45 Jahren zurück.
    CONCLUSIONS: Der Notability Bias, der patriarchische Ansatz in der Erstellung von Familienstammbäumen und die Müttersterblichkeit sind mögliche Ursachen für diese Beobachtungen in FamiLinx. In der Familienrekonstitution ist die mit der Mobilität einhergehende Zensierung ein Erklärungsansatz.

    研究全面疼痛课程对医学生对疼痛患者和阿片类药物管理的预先存在的看法和态度的直接影响。
    主要学术医学中心的一年级医学生于2020年6月参加了必修的实习前疼痛课程,并完成了课程前和课程后的在线调查,其中包括Likert量表关于他们对疼痛管理和阿片类药物相关问题的态度的问题。此外,调查包括一个自由文本问题,学生们列出了听到“阿片类药物”这个词时想到的前五个词。这些词被归类为“专业”或“躺”词,进一步被归类为“积极”,\"negative\",或“中性”的含义。数据分析包括描述性统计,以及非参数检验和参数检验。
    119名学生中有54名回答了测试前和测试后的调查,并被纳入配对分析。术前专业词使用数(M=1.21,SD=0.97)与术后专业词使用数(M=2.40SD=1.33)差异有统计学意义;t(52)=-6.39,P<0.001。学生在课程结束后(M=0.81,SD=0.63)也比使用前(M=0.23,SD=0.43)更多;t(51)=-5.98,P<0.001。学生在课程后对几个关键的李克特量表问题的回答表明,人们对照顾疼痛患者的态度发生了重大转变。例如,学生承认在适当的情况下提供阿片类药物治疗慢性疼痛更舒适(P<0.001),并提高了处理复杂疼痛病例的兴趣(P<0.001)。
    结果表明,多学科的疼痛课程可以大大提高一年级医学生对疼痛管理的态度,慢性疼痛患者,以及围绕阿片类药物的复杂问题。
    UNASSIGNED: To examine the immediate effects of a comprehensive pain course on medical students\' pre-existing perceptions and attitudes toward pain patients and opioid management.
    UNASSIGNED: First-year medical students at a major academic medical center enrolled in a required pre-clerkship pain course in June 2020 and completed pre- and post-course online surveys with Likert-scale questions about their attitudes toward pain management and opioid-related issues. Additionally, the surveys included a free-text question where the students listed the first five words that came to mind when hearing the word \"opioids\". These words were categorized as \"professional\" or \"lay\" words and further as having \"positive\", \"negative\", or \"neutral\" connotations. Data analyses included descriptive statistics, as well as non-parametric and parametric tests.
    UNASSIGNED: Fifty-four of the 119 students responded to pretest and posttest surveys and were included in paired analyses. There was a significant difference between the number of professional words used before (M=1.21, SD=0.97) and after the course (M=2.40 SD=1.33); t(52)=-6.39, P<0.001. Students also used more lay-positive words after the course (M=0.81, SD=0.63) than they used pre-course (M=0.23, SD=0.43); t(51)=-5.98, P<0.001. Students\' post-course responses to several key Likert-scale questions showed significant shifts toward more positive attitudes about caring for patients with pain. For example, students acknowledged greater comfort in providing opioids for chronic pain (P<0.001) where appropriate, and enhanced interest in handling complex pain cases (P<0.001).
    UNASSIGNED: Results showed that a comprehensive, multi-disciplinary pain course could greatly enhance first-year medical students\' attitudes toward pain management, chronic pain patients, and the complex issues surrounding opioids.
