To provide a comprehensive summary of available literature on the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) of patient-reported outcome measures (PROMs) for various shoulder conditions and outcomes and to identify factors that influence these metrics.
Over the past 2 years, there has been an increasing interest in utilizing MCID, SCB, and PASS as a gauge to evaluate the success of an intervention for shoulder conditions. Efforts at calculating these thresholds have yielded multiple and inconsistent values and are further compounded by the proliferation of different PROMs in the shoulder literature. The MCID, SCB, and PASS values of shoulder PROMs vary widely with study-specific characteristics, including patient demographics, shoulder pathology, treatment, shoulder instrument, study methodology, and calculation method. The differences in these factors are not inconsequential and could lead to large discrepancies in threshold values. It is crucial that clinicians are mindful of these variables when designing future studies to calculate these metrics or when utilizing previously published values to determine the success of an intervention.
全面总结关于各种肩部疾病及预后的患者报告结局指标（PROMs）的最小临床重要差异（MCID）、显著临床获益（SCB）和患者可接受症状状态（PASS）的现有文献，并确定影响这些指标的因素。
在过去两年中，人们越来越关注利用MCID、SCB和PASS作为评估肩部疾病干预成功与否的标准。计算这些阈值的努力产生了多个不一致的值，并且肩部文献中不同PROMs的激增使情况更加复杂。肩部PROMs的MCID、SCB和PASS值因研究的特定特征而有很大差异，包括患者人口统计学、肩部病理学、治疗方法、肩部测量工具、研究方法和计算方法。这些因素的差异并非无关紧要，可能导致阈值出现很大差异。临床医生在设计未来研究以计算这些指标或利用先前发表的值来确定干预的成功与否时，务必注意这些变量。
