结果评分:它们测量什么,以及不测量什么 资料
什么是患者报告结局指标
患者报告结局指标(Patient-Reported Outcome Measure, PROM)是一份关于您自身健康状况的问卷。它不是对您进行的检查,而是询问您的感受以及您能够完成的活动。这类问卷至少自20世纪60年代起就已存在,尽管其名称是后来才出现的 [1]。
您的医生无法通过X光片或体格检查看到疼痛或疲劳。研究指出,关节活动度和肌力等指标可能不如人们想象的那么可靠,因此越来越多的诊所现在会直接询问患者 [2]。这正是这些问卷所填补的空白:它们捕捉了您对自己功能和生活质量的看法,这是任何扫描或临床检查都无法观察到的 [3]。
其中一些问卷是关于日常生活的长问题列表。较新的问卷,例如通过美国研究网络开发的PROMIS量表,更短且更精确 [4]。您可能用笔在纸上填写,也可能通过手机短信回答几个问题。研究发现,这两种方式得出的评分具有可比性 [5]。
您的回答会被评分并随时间进行比较,以便在治疗前后跟踪变化。研究人员还使用它们来比较大量患者群体的结果,尽管全球各关节登记处收集的数据并不统一或完整,这可能使比较变得更加困难 [6]。
有一点值得了解:这些评分衡量的是患者群体的平均水平。它们不能预测任何个人的具体感受。您的医生会将您的评分作为信息的一部分,结合您的体格检查结果和您自己的目标来使用,而不是将其作为对您康复情况的最终判定。
为何重要
这些问卷承担两项不同的功能,了解其区别很有帮助。
第一项功能是随时间追踪您的状况。您会在治疗前和治疗后填写同一份问卷,以便您的医疗团队能够观察您的变化程度。因此,您自己的分数最有用的地方在于作为您自身进步的指标,而非用于与他人排名的数字。两个人可能从不同的起点出发,最终得到不同的分数,但两人都可能取得了良好的效果。
第二项功能发生在更大的尺度上。当许多患者完成相同的问卷时,可以对整个群体进行比较,从而在整个人群范围内评估治疗和服务。这就是研究结果如何融入更广泛的护理决策的过程。常规收集这些信息被描述为重视患者所关心之事的医疗保健的未来 [1],将其纳入常规骨科就诊是可行的,并且能为医生和患者提供坚实的信息以共同做出决策 [2]。
有一个值得了解的注意事项。推动这些问卷发展的力量主要来自研究人员和医疗支付方,且并不总是专注于从患者角度改善护理 [3]。分数使用方式中的一些局限性可能解释了为何填写这些问卷并不总能带来患者结果的改善 [4]。
那么这对您意味着什么?您的分数是医生结合体格检查和个人目标所使用的信息之一。它不是评分,也不是预测。它提供的方式是让您能感受到但他人看不到的变化得以言表,并让您的进步成为更大图景的一部分,有助于评估所有人的护理。
结果的含义
您现在有一个分数。它实际上告诉您什么?
首先要了解的一点是:哪个方向更好取决于问卷本身。表格本身或向您提供表格的人会告诉您评分的方向。
数值上的微小变化可能意义不大。研究人员一直在研究这个问题,并使用一些概念来帮助解读分数。其中一个概念称为最小临床重要差异(minimal clinically important difference),即患者在日常生活中实际能察觉到的最小变化。另一个概念称为患者可接受症状状态(patient acceptable symptom state),即患者感觉良好到认为其症状可以接受的程度 [1]。
关键在于:没有单一的阈值适用于所有人。这些指标的值在不同医院和不同患者群体之间存在差异 [2]。不同的计算方法会得出截然不同的结果 [3],且任何单一数值都应被视为一个范围,而非一条明确的界限 [4]。因此,如果您的分数仅发生小幅变动,这本身并不能说明太多。稍后再次测量的相同分数及其变化趋势,能传达更多的信息。
此外,值得注意的是,变化可能在统计上显著,但并非您能感受到的变化。关于这些测量指标的研究指出,数字上显示出的差异可能与对您而言重要的差异并不一致 [5]。这就是为什么您的医疗团队会将您的分数与体格检查以及您个人的目标结合起来考量,而不是将数字视为完整的答案。
还有一个局限性。目前尚无单一的问卷成为衡量功能的标准方式。一项综述发现,目前有15种不同的工具用于此目的,这也是研究人员不断呼吁加强标准化的原因 [6]。所有这些测量指标仍需进一步研究以确认其性能 [7]。
因此,请将您的分数视为多个信号中的一个。询问发生了什么变化、变化幅度多大,以及您是否能感受到这种变化。
它无法告诉你的内容
问卷评分不能用于诊断任何疾病。它记录的是您的感受,而非您身体存在的具体问题。它也不决定您应该接受何种治疗。这一决定应由您与医生共同作出,结合您的体格检查、您的目标以及您自身的判断,并辅以该评分数值。
单一结果也并非对您当前状况的定论。这些评分衡量的是患者群体的平均水平,而平均值掩盖了个体体验的差异范围。两个人可能拥有相同的评分,但对其感受却截然不同。您个人的经历比您在群体中的位置更为重要。
有一些值得了解的实用陷阱。由于尚无单一问卷确立标准问题集 [1],某些问题可能遗漏了对您而言最重要的内容。部分结果会聚集在量表的最高或最低端,因此您感受上的真实变化可能无法在数值上体现出来。此外,用于判断变化是否具有临床意义的阈值在不同医院和不同患者群体之间各不相同 [2],因此您评分的微小变动在不同情境下并不具有相同的含义。
诚实的总结是:您的评分是多个信号中的一个。它能为他人无法察觉的情况提供描述,并能追踪您随时间的进展。但它无法告诉您哪里出了问题,无法为您选择治疗方案,也无法用一个数字概括您的康复过程。
核心要点
这些问卷擅长一件事:用您自己的语言描述您的感受和能力,以便随时间进行追踪。它们不是诊断,不是治疗选择,也不是对康复结果的预测。值得记住的一点是,您的得分只是多个信号之一。您的医疗团队会将其与体格检查以及您自身的目标结合起来解读,因此单凭一个数字永远无法反映全貌。

Evidence & references
This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.
Overview
- Patient-reported outcome measures (PROMs) are critical for capturing the patient's perspective on health status, which cannot be observed through clinical tests or imaging [48].
- Standardized health-related outcome measures require evidence for change and a way to interpret change within individuals or difference between groups [3].
- The minimum clinically important difference (MCID) defines the smallest amount an outcome must change to be meaningful to patients [46].
- The minimum clinically important difference, the standard error of measurement, and the minimum detectable change are proposed as indicators for the clinical interpretation of test scores [1].
- Lack of consensus in the literature has led to confusion about which measurement properties are relevant, which concepts they represent, and how to assess these measurement properties in terms of design requirements and preferred statistical methods [16].
- Consensus was reached on how a comprehensive research question can be deduced from the design of a reliability study to determine how the results of a study inform us about the quality of the outcome measurement instrument at issue [2].
- An appropriate and validated measure that is suitable for both the particular study population and the reason for collecting the PROMs data should be chosen [6].
- Providing access to PROM scores without clearly understanding how and why surgeons may consider using them can result in expensive and underused systems that add little value [44].
- Reasons for limited use of PROMs by orthopedic surgeons include a lack of knowledge on how to use them and the perception that it is too time-consuming to add to regular clinical routine [45].
- Limitations of PROM use in clinical practice shed light on why PROM use may not always improve patient outcomes and provide considerations for the design and implementation of future PROM initiatives [47].
- PROMIS measures are efficient and precise tools, and their use is expected to continue to increase across medical and surgical specialties as health systems and payers expand their definition of healthcare quality to include patient-reported health outcomes [49].
How It Works
Interpretation and Clinical Utility
- The minimum clinically important difference, standard error of measurement, and minimum detectable change are proposed as indicators for the clinical interpretation of test scores [1].
- Scores from tools designed to measure outcomes that matter to patients have been developed over the past 30 years, but few are used routinely at the point of care [21].
- An appropriate and validated measure suitable for the particular study population and the reason for collecting data should be chosen for patient-reported outcome measures [6].
Reliability and Validity Assessment
- The two-way mixed-effect analysis of variance model with interaction for the absolute agreement between single scores is recommended to assess test-retest reliability for patient-reported outcome measures [4].
- Consensus was reached on how a comprehensive research question can be deduced from the design of a reliability study to determine how results inform about the quality of the outcome measurement instrument [2].
- The Patient-Reported Outcomes Measurement Information System (PROMIS) item banks demonstrated good reliability across most of the score distributions [43].
- The MOS short form health survey (SF-36) scales met required internal consistency criteria with Cronbach alpha coefficients equaling or exceeding 0.70 in a study conducted in India [33].
- An assessment tool for brachial plexus regional anesthesia performance demonstrated construct validity by reliably discriminating between different levels of training, with senior trainees performing significantly better than junior trainees on the global rating scale [35].
Standardization and Data Collection
- Current data collection of patient-reported outcome measures is neither uniform nor complete across the world's registries, which may impact data validity and the ability to compare outcomes [8].
- No key measure was identified to capture functional status in advanced musculoskeletal physiotherapy practice, with 15 different tools utilized, highlighting the need for greater standardization of outcome measurement [40].
- Outcomes assessed on numeric rating scales and reported with text-messages on mobile phones provide comparable scores to questionnaires completed with pen and paper [7].
Limitations and Gaps
- Physical outcome measures such as range of motion and strength are not as reliable measures as one would think, and are being changed for the use of patient reported outcomes [15].
- All patient-reported outcome measures for intermittent claudication require further validation studies to fill the gaps in their measurement properties [32].
How It Is Used
- Clinicians can use the minimum clinically important difference, standard error of measurement, and minimum detectable change to interpret test scores [1].
- Standardized health-related outcome measures require evidence for change and a method to interpret change within individuals or differences between groups [3].
- Clinicians must be cautious when accepting a minimal clinically important difference score at face value due to wide variability in established scores for a single outcome scale [5].
- Outcomes assessed on numeric rating scales via text messages on mobile phones provide comparable scores to those completed with pen and paper questionnaires [7].
- Investigators can choose thresholds to dichotomize responses on health-related quality of life measures based on absolute scores or change scores to facilitate interpretation [10].
- Promoting ownership and correct use of the measure by clinicians can improve practice and the quality of care through patient-reported outcome measure data use in clinical decision-making [11].
- The minimal important difference is not an immutable characteristic and may vary by population and context, meaning no single minimal important difference is valid for all study applications [14].
- Routine use of patient-reported outcome measures has the potential to help transform healthcare [18].
- High variability in scale choice and the use of measures not validated in pediatrics make comparative outcomes research difficult in the pediatric sports population [19].
- High-quality systematic reviews on measurement instruments are advocated to recommend the best available outcome measurement instrument [20].
- Few outcome measurement tools have been used routinely at the point of care despite being developed over the past 30 years [21].
- Further studies are needed to provide validated outcome measures to ensure the accuracy of reported results and conclusions after rib fracture [22].
- Comparative effectiveness research requires accurate assessments of patient numbers, follow-up completeness, clinical outcomes, and care settings [34].
- Recommendations for the selection of patient-assessed measures of health outcome are needed [36].
- Limiting follow-up to automated methods has the potential to transform the design and conduct of outcome-based research to provide substantially better research value in large prospective cohorts [38].
- There are challenges in using patient-reported outcomes in clinical practice [39].
- The routine use of patient-reported outcomes in clinical practice is assessed for its impact on the process of care, patients' and professionals' experiences of care, and health outcomes [42].
Interpreting the Results
Measurement Properties and Reliability
- Consensus was reached on deducing a comprehensive research question from the design of a reliability study to determine how results inform the quality of an outcome measurement instrument [2].
- The two-way mixed-effect analysis of variance model with interaction for the absolute agreement between single scores is recommended for assessing test-retest reliability of patient-reported outcome measures [4].
- Range of motion and strength are not as reliable measures as one would think [15].
Minimal Clinically Important Difference (MCID)
- Clinicians must be cautious in accepting an MCID score at face value given the wide variability of established MCID scores available for a single outcome scale [5].
- The recommended approach for estimating the minimal important difference is to use several anchor-based methods with relevant clinical or patient-based indicators, examine distribution-based estimates as supportive information, and triangulate on a single value or small range of values [9].
- The Minimal Clinically Important Difference (MCID) is a point estimate that should always be reported with its associated 95% CI, as there is no basis for considering a sample-derived MCID a singular threshold to be crossed [12].
- The minimal clinically important difference (MCID) is an imperfect solution to a complicated problem, and different methods used to calculate MCID lead to highly heterogeneous values [13].
- The minimal important difference (MID) is not an immutable characteristic but may vary by population and context, and no one MID may be valid for all study applications [14].
- The minimal clinically important difference (MCID) is a low bar that patients do not seek when undergoing surgery; instead, they aim for substantial clinical benefit or a patient acceptable symptom state (PASS) [17].
- The calculation of the minimal clinically important difference (MCID) needs to be correlated with changes in scores on the rating scale and external anchors [24].
- A systematic approach exists to triangulate on the Minimal Clinically Important Difference (MCID) using both distribution-based and anchor-based methods [29].
Reporting and Interpretation Frameworks
- Outcomes assessed on numeric rating scales and reported with text-messages on mobile phones or with questionnaires completed with pen and paper provide comparable scores [7].
- Investigators can choose thresholds to dichotomize responses on HRQL based on absolute scores or change scores to facilitate interpretation [10].
- A standardized reporting of patient-reported outcome measures (PROMs) has been proposed that incorporates the minimum clinically important difference (MCID) and the patient acceptable symptom state (PASS), introducing a 'clinical relevance ratio' to report the proportion of patients achieving clinical importance rather than relying solely on mean changes [23].
- Routine use of patient reported outcome measures (PROMs) has the potential to help transform healthcare [18].
Limitations and Pitfalls
Measurement Properties and Reliability
- Lack of consensus in the literature has led to confusion about which measurement properties are relevant, which concepts they represent, and how to assess these properties in terms of design requirements and preferred statistical methods [16].
- To assess test-retest reliability for patient-reported outcome measures, the two-way mixed-effect analysis of variance model with interaction for the absolute agreement between single scores is recommended [4].
- Consensus was reached on how a comprehensive research question can be deduced from the design of a reliability study to determine how the results inform about the quality of the outcome measurement instrument [2].
- A 10-item computerized adaptive test (CAT) eliminated floor and decreased ceiling effects, achieving a small standard error (≤ 2.2) across scores from 20 to 50 with reliability ≥ 0.95 for a representative US sample [31].
Minimal Clinically Important Difference (MCID)
- The recommended approach is to estimate the minimal important difference based on several anchor-based methods with relevant clinical or patient-based indicators, examine various distribution-based estimates as supportive information, and triangulate on a single value or small range of values [9].
- MCIDs expressed as effect sizes reduce bias, which mainly results from dependency on the baseline score [41].
- Researchers, clinicians, and healthcare policy decision makers can consider using a specific instrument to evaluate the design, conduct, and analysis of studies estimating anchor based minimal important differences [30].
Data Collection and Standardization
- The current data collection of patient-reported outcome measures (PROMs) is neither uniform nor complete across the world's registries, which may impact data validity and the ability to compare outcomes [8].
- The high variability in scale choice and the use of measures not validated in pediatrics make comparative outcomes research difficult [19].
- Only 57% of primary medical providers are using patient reported outcome measures within their practice, with the information largely used for research rather than clinical decision-making [27].
- Further studies are needed to provide validated outcome measures to ensure accuracy of the reported results and conclusions [22].
Clinical Application and Interpretation
- The authors propose using the minimum clinically important difference, the standard error of measurement, and the minimum detectable change as indicators for the clinical interpretation of test scores [1].
- Integrating standardized patient-reported outcomes into routine orthopaedic visits is feasible and improves practice efficiency by providing actionable objective data for shared decision-making [26].
- The ability to collect patient-reported outcome (PRO) data in real time and share this information with patients to inform clinical decision making represents the future of value-based healthcare, moving beyond research-focused assessments to guide treatment consistent with patient preferences [25].
- Promoting ownership and correct use of the measure by clinicians can potentially improve practice and the quality of care provided through patient-reported outcome measure data use in clinical decision-making [11].

- [L4] The reasons provided included a lack of knowledge on how to use PROMs and the perception that it is too time-consuming to add to regular clinical routine. [45] (10.1186/s13018-020-02135-1)
- [Paper] The MCID defines the smallest amount an outcome must change to be meaningful to patients. [46] (10.1001/jama.2014.13128)
- [L4] These limitations shed some light on why PROM use may not always improve patient outcomes and provide considerations for the design and implementation of future PROM initiatives. [47] (10.1007/s11136-021-03003-z)
- [L5] This editorial argues that Patient Reported Outcome Measures (PROMs) are critical for capturing the patient's perspective on health status, which cannot be observed through clinical tests or imaging. [48] (10.1136/bjsports-2014-093707)
- [L4] PROMIS measures are efficient and precise tools, and their use is expected to continue to increase across medical and surgical specialties as health systems and payers expand their definition of healthcare quality to include patient-reported health outcomes. [49] (10.5435/jaaos-d-24-00432)
