    肺癌是全球范围内老年人群中发病率和死亡率最高的恶性肿瘤。在肺癌亚型中,非小细胞肺癌(NSCLC)是最普遍的。随着年龄的增长,老年患者通常表现为合并症患病率增加,器官储备功能减弱,和药物药代动力学的改变,包括吸收,分布,新陈代谢,和间隙。这些因素共同导致其耐受治疗干预的能力降低。遗憾的是,关于晚期肺癌老年患者治疗的研究数据和证据很少。本文努力汇编和阐明增强治疗方法的策略,目的是帮助临床决策。在选择老年晚期NSCLC患者的临床治疗方式之前,应该进行全面评估,考虑到各个方面,包括肿瘤特征,患者年龄,生理状态,和合并症的存在。治疗策略应分层实施,从而为患有晚期NSCLC的老年患者提供定制个性化治疗方法的机会。面对晚期NSCLC的老年患者的人口统计学表现出复杂的景观,其特征是复杂的潜在条件。必须优化治疗策略。
    Lung cancer stands as a malignant neoplasm bearing the highest burden of morbidity and mortality within the elderly population on a global scale. Among the lung cancer subtypes, non-small cell lung cancer (NSCLC) prevails as the most prevalent. As age advances, elderly patients often present with an increased prevalence of comorbidities, diminished organ reserve function, and alterations in drug pharmacokinetics, including absorption, distribution, metabolism, and clearance. These factors collectively contribute to a reduction in their capacity to tolerate therapeutic interventions. Regrettably, there exists a paucity of research data and evidence regarding the management of elderly patients afflicted by advanced lung cancer. This article endeavors to compile and elucidate strategies for the enhancement of treatment approaches, with the aim of aiding clinical decision-making. Prior to the selection of clinical treatment modalities for elderly patients with advanced NSCLC, a comprehensive assessment should be conducted, taking into account various facets, including tumor characteristics, patient age, physiological status, and the presence of comorbidities. The treatment strategy should be implemented in a tiered fashion, thereby affording the opportunity for the tailoring of individualized therapeutic approaches for elderly patients afflicted by advanced NSCLC. The demographic of elderly patients confronting advanced NSCLC presents a complex landscape marked by intricate underlying conditions, necessitating the imperative optimization of treatment strategies.

    背景:多发性硬化症(MS)是一种影响中枢神经系统的慢性炎症性疾病,通常导致患者睡眠质量差和生活质量(QoL)下降。MS的睡眠障碍并不总是与焦虑等其他症状呈线性关系,抑郁症,疲劳,或疼痛。各种方法,包括减压技术,如基于正念的干预措施,已被提议管理MS相关的睡眠问题。
    目的:本研究的目的是使用主观(问卷调查)和客观(电子便携式设备)措施评估基于正念的身体扫描技术对MS患者睡眠质量和QoL的影响。
    方法:进行了一项单病例研究,涉及一名被诊断为复发缓解型MS的31岁女性。患者每天在睡前练习基于正念的身体扫描技术,并将结果与基线评估的测量结果进行比较。
    结果:基于正念的身体扫描干预对睡眠质量和整体QoL均有积极影响。生物识别数据显示,在干预期间,每日压力水平与睡眠质量之间存在明显的分离。尽管自我报告工具显示出重大改进,注意到潜在的偏见。
    结论:虽然这项研究仅限于单个患者,有希望的结果提示需要进行更大规模的进一步调查.这些发现强调了基于正念的身体扫描技术在管理MS患者的睡眠障碍和增强QoL方面的潜在益处。
    BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory disease affecting the central nervous system, often leading to poor sleep quality and diminished quality of life (QoL) for affected patients. Sleep disturbances in MS do not always correlate linearly with other symptoms such as anxiety, depression, fatigue, or pain. Various approaches, including stress reduction techniques such as mindfulness-based interventions, have been proposed to manage MS-related sleep issues.
    OBJECTIVE: The aim of this study was to evaluate the effects of the mindfulness-based body scan technique on sleep quality and QoL in patients with MS using both subjective (questionnaires) and objective (electronic portable device) measures.
    METHODS: A single-case study was performed involving a 31-year-old woman diagnosed with relapsing-remitting MS. The patient practiced the mindfulness-based body scan technique daily before bedtime and outcomes were compared to measures evaluated at baseline.
    RESULTS: The mindfulness-based body scan intervention demonstrated positive effects on both sleep quality and overall QoL. Biometric data revealed a notable dissociation between daily stress levels and sleep quality during the intervention period. Although self-report instruments indicated significant improvement, potential biases were noted.
    CONCLUSIONS: While this study is limited to a single patient, the promising outcomes suggest the need for further investigation on a larger scale. These findings underscore the potential benefits of the mindfulness-based body scan technique in managing sleep disturbances and enhancing QoL among patients with MS.

    目的:医学影像健康素养的重要性得到了广泛认可,然而,目前的景观仍然没有得到充分的理解。本研究旨在探讨与医学影像相关的健康素养研究的范围。
    方法:范围审查。
    方法:使用三个在线书目数据库进行了范围审查,即PubMed,ScienceDirect,和CINAHL。我们采用了健康素养的概念,作为临床风险和个人资产,来指导这次审查。
    结果:在311篇独特文章中,39符合我们的选择标准。作者确定了五个主题(类别):与接受医学影像检查结果的患者进行适当的沟通,医学成像的适当使用,电子健康素养的类别和特征,疾病/恶化预防,和病人的教育。此外,确定了17种健康素养评估工具,包括11个原创作品。最后,这次范围界定审查提出了11项建议,提供对方法的有价值的见解,考虑因素,以及促进健康素养的策略。
    结论:医学影像中的健康素养研究涵盖了临床和公共卫生观点,造福于不同的人群,不管潜在的医疗条件。值得注意的是,这些研究中使用的大多数评估工具都是作者生成的,阻碍交叉研究比较。鉴于医学图像传达直观信息的先天能力,这些图像不仅使接受医学成像检查的患者受益,但它们也具有提高公共卫生素养的巨大潜力。健康素养与医学影像紧密相关,相互促进。
    OBJECTIVE: The importance of health literacy in medical imaging is well recognized, yet the current landscape remains inadequately understood. This study aims to explore the extent of health literacy studies contextualized to medical imaging.
    METHODS: Scoping review.
    METHODS: A scoping review was conducted using three online bibliographic databases namely, PubMed, ScienceDirect, and CINAHL. We have adopted the concept of health literacy, as a clinical risk and personal asset, to guide this review.
    RESULTS: Of 311 unique articles, 39 met our selection criteria. Five themes (categories) were identified by the authors: appropriate communication with patients who receive medical imaging test results, appropriate usage of medical imaging, classes and characteristics of eHealth literacy, disease/deterioration prevention, and patient education. Additionally, 17 health literacy assessment tools were identified, including 11 original creations. Finally, 11 recommendations have emerged from this scoping review, offering valuable insights into methods, considerations, and strategies for promoting health literacy.
    CONCLUSIONS: Health literacy studies in medical imaging cover both clinical and public health perspectives, benefiting diverse populations, regardless of underlying medical conditions. Notably, the majority of assessment tools used in these studies were author-generated, hindering cross-study comparisons. Given the innate capacity of medical images to convey intuitive information, those images do not solely benefit the patients who are given medical imaging examinations, but they also hold significant potential to enhance public health literacy. Health literacy and medical imaging are closely associated and mutually reinforce each other.

    存在儿童慢性疼痛评估工具,但可能无效,可靠,对于有功能的人群来说是可行的,认知或沟通限制,例如,脑瘫(CP)。本研究旨在(i)确定用于儿童和年轻人的慢性疼痛评估工具,并对其测量特性进行评分;(ii)开发CP特定的可行性评估工具,以评估CP工具的可行性;(iii)根据报告方法对工具进行分类。
    评估工具通过文献综述确定。使用基于COnsensus的健康测量指标选择标准对其测量特性进行评级。CP特定的可行性评级工具已开发并用于对工具进行评级。
    确定了57种慢性疼痛评估工具。六个具有CP的内容有效性,其中四个使用代理报告。42个工具被认为对CP患者是可行的;24个自我报告和18个观察/代理报告。对于无法自我报告的CP患者,只有儿科疼痛档案具有内容有效性和可行性。
    几乎没有有效的,可靠和可行的工具来评估慢性疼痛CP。需要进一步的研究来修改工具,使具有认知限制和/或复杂沟通的人能够自我报告疼痛。
    现有的慢性疼痛评估工具很少能够在所有患有脑瘫(CP)的年轻人中使用。需要对自我报告工具进行修改,以改善患有认知障碍或使用替代和增强交流的年轻人的访问。对于无法自我报告的年轻人,具有最强可行性和测量特性的疼痛评估工具是儿科疼痛概况。临床医生将需要考虑一系列慢性疼痛评估工具,以评估对脑瘫年轻人重要的生物心理社会领域。
    UNASSIGNED: Chronic pain assessment tools exist for children, but may not be valid, reliable, and feasible for populations with functional, cognitive or communication limitations, for example, cerebral palsy (CP). This study aimed to (i) identify chronic pain assessment tools used with children and young people and rate their measurement properties; (ii) develop a CP specific feasibility rating tool to assess the feasibility of tools in CP; and (iii) categorise tools according to reporting method.
    UNASSIGNED: Assessment tools were identified by literature review. Their measurement properties were rated using the COnsensus based standards for the Selection of health Measurement INstruments. The CP specific Feasibility Rating Tool was developed and used to rate the tools.
    UNASSIGNED: Fifty-seven chronic pain assessment tools were identified. Six have content validity for CP, four of these use proxy-report. Forty-two tools were considered feasible for people with CP; 24 self report and 18 observational/proxy-report. Only the Paediatric Pain Profile has content validity and feasibility for people with CP unable to self-report.
    UNASSIGNED: There are few valid, reliable and feasible tools to assess chronic pain in CP. Further research is required to modify tools to enable people with cognitive limitations and/or complex communication to self-report pain.
    Few of the existing chronic pain assessment tools are feasible or valid to use with all young people with cerebral palsy (CP).Modifications to self-report tools are needed to improve access for young people who have cognitive impairment or use alternative and augmentative communication.The pain assessment tool with the strongest feasibility and measurement properties for young people who cannot self-report is the Paediatric Pain Profile.Clinicians will need to consider a range of chronic pain assessment tools to assess the biopsychosocial domains important to young people with cerebral palsy.

    犬认知功能障碍(CCD)是一种常见的,但未被诊断的神经退行性疾病影响老年犬。早期开始治疗最有效,因此,在疾病的早期阶段识别轻度认知能力下降被认为是重要的。
    为了比较三种不同标准筛查问卷的结果[犬痴呆量表(CADES),犬认知评估量表(CCAS),和犬认知功能障碍评定量表(CCDR)]用于CCD诊断。可培训性,疼痛敏感性,此外,我们还使用犬科动物行为评估和研究问卷(C-BARQ)评估了恐惧,以评估三种痴呆量表和行为之间的关联。
    一项包含所有提到的问卷的在线调查是为老年犬只的主人设计并分发的。
    分析来自597只狗的数据。总的来说,三个CCD问卷的得分相互关联良好,尤其是那些CADES和CCAS。CADES在识别已经轻度至中度认知障碍的狗时更敏感,而其他人则将它们归类为仍在正常衰老。随着年龄的增长,所有问卷的CCD得分都有所增加,空间取向是CCD开发的关键特征。C-BARQ评估的可训练性随着CCD体征的严重程度而显著下降,而疼痛敏感性增加。在轻度而非重度CCD的动物中,恐惧和焦虑明显。与CCAS相比,基于C-BARQ的这些关联与CADES和CCDR的关系更清楚。
    筛选问卷的选择会影响对CCD认知状态和严重程度的评估。严重程度分类的阈值差异很大,可能会对可靠的评估产生影响。需要进一步的纵向研究,以确定本研究中调查的哪一份问卷最适合早期检测CCD。
    UNASSIGNED: Canine cognitive dysfunction (CCD) is a common, yet underdiagnosed neurodegenerative disease affecting older dogs. Treatment is most effective when started early, so identifying mild cognitive decline in the earlier stages of the disease is considered important.
    UNASSIGNED: To compare the results of three different standard screening questionnaires [Canine Dementia Scale (CADES), Canine Cognitive Assessment Scale (CCAS), and Canine Cognitive Dysfunction Rating Scale (CCDR)] for CCD diagnosis. Trainability, pain sensitivity, and fear were additionally assessed with the Canine Behavioral Assessment and Research Questionnaire (C-BARQ) in order to evaluate associations between the three dementia scales and behavior.
    UNASSIGNED: An online survey containing all the mentioned questionnaires was designed for and distributed among owners of elderly dogs.
    UNASSIGNED: Data from 597 dogs were analyzed. Overall, the scores of the three CCD questionnaires correlated well with each other, especially those of the CADES and CCAS. The CADES was more sensitive in identifying dogs with already mild to moderate cognitive impairment, while the others classified them as still undergoing normal aging. CCD scores increased for all questionnaires with age with spatial orientation being a key feature in CCD development. Trainability assessed with the C-BARQ decreased significantly with severity of CCD signs, while pain sensitivity increased. Fear and anxiety was pronounced in animals with mild but not with severe CCD. These associations based on the C-BARQ were more clearly observable in relation to CADES and CCDR than CCAS.
    UNASSIGNED: The choice of screening questionnaire impacts the evaluation of cognitive status and severity of CCD. Thresholds for severity classification differ significantly and may have an impact on reliable assessment. Further longitudinal studies are required to determine which of the questionnaires investigated in this study is best suited for early detection of CCD.

    背景:网络色情使用,越来越常见的活动,引发了无数的社会心理和临床问题。虽然需要筛选和衡量其问题维度,关于现有评估工具的充分性存在争议。
    目的:该研究比较了两种基于不同理论框架的用于测量病理性在线色情使用(POPU)的工具,一种符合DSM-5标准和六成分成瘾模型,另一种符合ICD-11标准。
    方法:一个国际样本1,823名成年人(平均年龄=31.66,SD=6.74)回答了一个在线问卷,其中包括有问题色情消费量表的简短版本(PPCS-6)和特定互联网使用障碍评估标准(ACSID-11)。阶乘,相关,并对数据进行了网络分析。
    结果:这两种工具都充分筛选了在线“上瘾”行为,但ACSID-11在评估临床风险程度方面更胜一筹.
    结论:取决于评估的具体目标(筛查与临床诊断),这两种在线色情测量工具都可能有用。
    BACKGROUND: Online pornography use, an ever more common activity, has raised myriad psychosocial and clinical concerns. While there is a need to screen for and measure its problematic dimension, there is a debate about the adequacy of existing assessment tools.
    OBJECTIVE: The study compares two instruments for measuring pathological online pornography use (POPU) that are based on different theoretical frameworks-one in line with DSM-5 criteria and the six-component addiction model and one in line with ICD-11 criteria.
    METHODS: An international sample of 1,823 adults (Mean age = 31.66, SD = 6.74) answered an online questionnaire that included the Short Version of the Problematic Pornography Consumption Scale (PPCS-6) and the Assessment of Criteria for Specific Internet-Use Disorders (ACSID-11). Factorial, correlational, and network analyses were conducted on the data.
    RESULTS: Both tools adequately screened for online \"addictive\" behavior, but the ACSID-11 was superior in assessing the degree of clinical risk.
    CONCLUSIONS: Depending on the specific aim of the assessment (screening vs. clinical diagnostics), both online pornography measurement tools may be useful.

    食品服务,必须符合食品生产的卫生标准,在大流行时期需要适应COVID-19协议。在这种情况下,对食品安全评估工具和卫生规程的研究有助于卫生控制措施的系统化,并有助于了解服务如何适应新的要求。因此,本研究旨在评估食品安全评估工具的结果与食品服务中应对COVID-19的卫生方案的依从性之间的关系.卫生检查在位于圣保罗市中心的40食品服务中进行-巴西。通过应用四个检查表来收集数据以评估以下方面:i.FBD的风险;ii.良好处理做法;iii.结构要求;以及iv.COVID-19卫生协议的实施。使用风险评分来解释风险评估工具,每个项目根据FBD的风险进行加权。使用违反项目的总体百分比来评估其他工具的结果。结果表明,在所评估的食品服务中,GHP的高风险占主导地位,并且违反良好处理规范和结构要求的比例很高。在大多数机构中,违反COVID-19健康协议的百分比是中等的。风险程度与违反良好处理规范(Spearmanρ=0.73;p<0.001)和结构要求(Spearmanρ=0.63;p<0.001)呈高度正相关。关于评估遵守COVID-19卫生协议的工具,发现与违反良好处理实践的中度相关性(斯皮尔曼ρ=0.65;p<0.001),重点是与食品处理人员相关的专题块。因此,对评估工具及其测量结果之间关系的讨论可能有助于改善参与检查活动的专业人员对这些工具的应用,使卫生控制措施更加系统化,并有助于降低FBD的风险。
    Food services, which must meet the sanitary standards for food production, needed to adapt to COVID-19 protocols in times of pandemic. In this context, the study of food safety assessment tools and sanitary protocols can contribute to the systematization of sanitary control actions and to the understanding how services have adapted to the new requirements. Thus, the present study aims to evaluate the relationships among the results of the assessment tools for food safety and adherence to the sanitary protocol for coping with COVID-19 in food services. Sanitary inspections were performed in 40 food services located in the center of the city of São Paulo - Brazil. Data were collected through the application of four checklists to evaluate the following: i. risk for FBD; ii. Good Handling Practices; iii. the structural requirements; and iv. The implementation of the COVID-19 sanitary protocol. The risk assessment tool was interpreted using a risk score, with each item weighted according to the risk for FBD. The results of the other tools were evaluated using the overall percentage of violated items. The results showed the predominance of high risk of GHP in the food services evaluated and a high percentage of violation of Good Handling Practices and structural requirements. The percentage of violation of the COVID-19 health protocol was moderate in most establishments. The degree of risk showed a high positive correlation with Good Handling Practices violations (Spearman ρ = 0.73; p < 0.001) and structural requirements (Spearman ρ = 0.63; p < 0.001). Regarding the tool for assessing adherence to the COVID-19 sanitary protocol, a moderate correlation was found with the violations of Good Handling Practices (Spearman ρ = 0.65; p < 0.001), with an emphasis on the thematic block relevant to food handlers. This discussion of the relationships among the results of the evaluation tools and their measurements may therefore be useful for improving the application of these tools by professionals involved in inspection activities, allowing the greater systematization of sanitary control actions and contributing to reduced risk of FBD.

  • 从实现以患者为中心的结果出发,患者满意度是评估医疗质量及其有效性的关键指标之一。如今,评估患者对医疗护理满意度的工具在世界各地得到广泛应用。监测人口对医疗服务满意度的世界经验对于更好地了解指标的动态并可能预测其在俄罗斯的水平是必要的。该研究的目的是分析现有的国家监测患者对医疗保健满意度的系统,并确定特定的既定趋势。搜索免费访问出版物是使用PubMed,谷歌学者,ResearchGate和eLibrary。关键词患者满意度,国家监测,满意度趋势,抽样包括55种出版物。分析确定,在许多国家/地区,对患者对医疗服务的满意度进行测量已成为常规实践,并且是评估医疗机构和整个医疗保健功效的组成部分。对医疗保健的初始满意度取决于众多人口变量,包括主要种族,人口的文化和民族,性别和年龄结构,社会经济条件,城市或农村人口的收入水平和患病率。大多数国家的满意度动态表明,但指标增长缓慢且统计上不显著,虽然在不同的满意度领域不同。确定的因素将在联邦一级考虑以制定正确的结论,并在区域一级考虑以制定相应的措施。
    The satisfaction of patients is one of key indicators used to assess quality of medical care and its effectiveness from point of view of achieving patient-oriented results. Nowadays, the tools assessing patient satisfaction with medical care are largely applied all over the world. The world experience of monitoring satisfaction of population with medical care is necessary for better understanding of dynamics of indicator and possible forecasting of its level in Russia. The purpose of the study is to analyze existing national systems of monitoring satisfaction of patient with medical care and to identify particular established trends. The search for free access publications was implemented using such databases as PubMed, Google Scholar, ResearchGate and eLibrary. The keywords patient satisfaction, national monitoring, satisfaction trends, The sampling included 55 publications. The analysis established that in many countries measurement of degree of satisfaction of patient with medical care become routine practice and integral part of of evaluation of efficacy of both medical organizations and health care in a whole. The initial level of satisfaction with medical care depends on multitude of population variables, including predominant race, culture and nationality of population, gender and age structure, social economic conditions, level of incomes and prevalence of urban or rural population. The dynamics of satisfaction level in most countries demonstrates steady, but slow and statistically insignificant increasing of indicators, though different in various domains of satisfaction. The identified factors are to be considered both at the Federal level to formulate correct conclusions and at the regional level to develop corresponding measures.

    背景:财务毒性,定义为癌症诊断及其治疗带来的客观财务负担和主观财务困境,是评估癌症患者及其家人生活质量的一个感兴趣的话题。目前的证据暗示社会心理中的金融毒性,经济和其他危害,导致整个诊断轨迹上的癌症预后不佳,治疗,支持性护理,生存和缓和。本文提出了一种虚拟共识的结果,根据迄今为止的证据基础,由欧洲医学肿瘤学会(ESMO)于2022年组织的癌症及其他癌症患者的金融毒性筛查和管理。
    方法:考虑到多学科,召集了一个由来自11个国家的19名专家组成的Delphi小组,卫生系统背景和研究相关性的多样性。国际专家小组分为四个工作组(WG),以解决与不同主题领域有关的问题:面临财务毒性风险的癌症患者;在医院/门诊环境中治疗初始阶段的财务毒性管理;在持续阶段和生命末期的财务毒性;以及癌症幸存者的财务风险保护,和癌症复发。在全面回顾文献后,声明由工作组编写,然后提交给整个小组进行进一步讨论和修改,和投票。
    结论:共制定了25项循证共识声明,其中回答了13个关于金融毒性的问题。它们包括证据摘要,实践建议/指导声明和政策建议与整个卫生系统相关。这些共识声明旨在更全面地了解金融毒性,并指导全球临床医生减轻其影响。强调进一步研究的重要性,最佳实践和准则。
    BACKGROUND: Financial toxicity, defined as both the objective financial burden and subjective financial distress from a cancer diagnosis and its treatment, is a topic of interest in the assessment of the quality of life of patients with cancer and their families. Current evidence implicates financial toxicity in psychosocial, economic and other harms, leading to suboptimal cancer outcomes along the entire trajectory of diagnosis, treatment, supportive care, survivorship and palliation. This paper presents the results of a virtual consensus, based on the evidence base to date, on the screening and management of financial toxicity in patients with and beyond cancer organized by the European Society for Medical Oncology (ESMO) in 2022.
    METHODS: A Delphi panel of 19 experts from 11 countries was convened taking into account multidisciplinarity, diversity in health system contexts and research relevance. The international panel of experts was divided into four working groups (WGs) to address questions relating to distinct thematic areas: patients with cancer at risk of financial toxicity; management of financial toxicity during the initial phase of treatment at the hospital/ambulatory settings; financial toxicity during the continuing phase and at end of life; and financial risk protection for survivors of cancer, and in cancer recurrence. After comprehensively reviewing the literature, statements were developed by the WGs and then presented to the entire panel for further discussion and amendment, and voting.
    CONCLUSIONS: A total of 25 evidence-informed consensus statements were developed, which answer 13 questions on financial toxicity. They cover evidence summaries, practice recommendations/guiding statements and policy recommendations relevant across health systems. These consensus statements aim to provide a more comprehensive understanding of financial toxicity and guide clinicians globally in mitigating its impact, emphasizing the importance of further research, best practices and guidelines.

    这项研究的目的是将严重脑损伤后意识障碍(DoC)患者的临床上有意义的改善或恶化与正常波动区分开。我们使用来自180名DoC参与者的临床试验数据计算昏迷恢复量表修订(CRS-R)的反应性指数。我们使用来自基线的CRS-R评分(临床试验中的登记)和四周的随访评估期来进行这些计算。为了提高精度,我们使用Rasch测量理论将序数CRS-R总分(0~23分)转换为0~100单位量表上的等间隔测量值.使用0到100单位的总Rasch措施,我们计算了基于分布的0.5标准差(SD)最小临床重要差异,使用95%置信区间可检测到的最小变化,和使用95%置信区间的条件最小可检测变化。基于分布的最小临床重要差异评估组水平的变化,而可检测的最小变化值评估个体水平的变化。最小临床重要差异和最小可检测变化是使用基线和四周时总测量的总体变异性得出的。为每个可能的CRS-RRasch人测量对生成条件最小可检测变化,并考虑整个尺度的标准误差变化。我们应用这些指数来确定两个子组中每个子组中做出超出测量误差的更改的参与者的比例,基于治疗臂(盐酸金刚烷胺或安慰剂)或基线Rasch人对意识状态的分类(即,反应迟钝的觉醒综合症和最低意识状态)。我们比较了每个治疗组中根据可检测到的最小变化做出改变的参与者的比例,并确定他们是否也改变为另一种意识状态。CRS-R反应性指数(使用0-100转化量表)如下:0.5SD最小临床重要差异=9个单位,最小可检测变化=11个单位,条件最小可检测变化范围为11到42个单位。对于金刚烷胺和安慰剂组,67%和58%的参与者使用最小的可检测变化表现出超出测量误差的变化,分别。对于反应迟钝的觉醒综合征和最低意识状态组,52%和67%的参与者使用最小的可检测变化超出测量误差,分别。在115名参与者(占总样本的64%)中,他们做出了超出测量误差的改变,29名参与者(25%)没有改变意识状态。反应性的CRS-R指数可以支持临床医生和研究人员辨别DoC患者的行为变化何时超过测量误差。值得注意的是,最小的可检测的变化可以支持对在意识状态内或跨意识状态做出真实变化的患者的检测。我们的发现强调,继续使用序数分数可能会导致对更改分数的程度和相关性的错误推断。
    The purpose of this study was to differentiate clinically meaningful improvement or deterioration from normal fluctuations in patients with disorders of consciousness (DoC) following severe brain injury. We computed indices of responsiveness for the Coma Recovery Scale-Revised (CRS-R) using data from a clinical trial of 180 participants with DoC. We used CRS-R scores from baseline (enrollment in a clinical trial) and a 4-week follow-up assessment period for these calculations. To improve precision, we transformed ordinal CRS-R total scores (0-23 points) to equal-interval measures on a 0-100 unit scale using Rasch Measurement theory. Using the 0-100 unit total Rasch measures, we calculated distribution-based 0.5 standard deviation (SD) minimal clinically important difference, minimal detectable change using 95% confidence intervals, and conditional minimal detectable change using 95% confidence intervals. The distribution-based minimal clinically important difference evaluates group-level changes, whereas the minimal detectable change values evaluate individual-level changes. The minimal clinically important difference and minimal detectable change are derived using the overall variability across total measures at baseline and 4 weeks. The conditional minimal detectable change is generated for each possible pair of CRS-R Rasch person measures and accounts for variation in standard error across the scale. We applied these indices to determine the proportions of participants who made a change beyond measurement error within each of the two subgroups, based on treatment arm (amantadine hydrochloride or placebo) or categorization of baseline Rasch person measure to states of consciousness (i.e., unresponsive wakefulness syndrome and minimally conscious state). We compared the proportion of participants in each treatment arm who made a change according to the minimal detectable change and determined whether they also changed to another state of consciousness. CRS-R indices of responsiveness (using the 0-100 transformed scale) were as follows: 0.5SD minimal clinically important difference = 9 units, minimal detectable change = 11 units, and the conditional minimal detectable change ranged from 11 to 42 units. For the amantadine and placebo groups, 70% and 58% of participants showed change beyond measurement error using the minimal detectable change, respectively. For the unresponsive wakefulness syndrome and minimally conscious state groups, 54% and 69% of participants changed beyond measurement error using the minimal detectable change, respectively. Among 115 participants (64% of the total sample) who made a change beyond measurement error, 29 participants (25%) did not change state of consciousness. CRS-R indices of responsiveness can support clinicians and researchers in discerning when behavioral changes in patients with DoC exceed measurement error. Notably, the minimal detectable change can support the detection of patients who make a \"true\" change within or across states of consciousness. Our findings highlight that the continued use of ordinal scores may result in incorrect inferences about the degree and relevance of a change score.
