Abstract：
BACKGROUND: Understanding minimal clinically important differences (MCID) in patient reported outcome measurement are important in improving patient care. The purpose of this study was to determine the MCID of Patient-Reported Outcome Measurement System (PROMIS) Physical Function (PF) domain for patients who underwent operative fixation of a tibial plateau fracture.
METHODS: All patients with tibial plateau fractures that underwent operative fixation at a single level 1 trauma center were identified by Current Procedural Terminology codes. Patients without PROMIS PF scores or an anchor question at two-time points postoperatively were excluded. Anchor-based and distribution-based MCIDs were calculated.
RESULTS: The MCID for PROMIS PF scores was 4.85 in the distribution-based method and 3.93 (SD 14.01) in the anchor-based method. There was significantly more improvement in the score from the first postoperative score (<7 weeks) to the second postoperative time (<78 weeks) in the improvement group 10.95 (SD 9.95) compared to the no improvement group 7.02 (SD 9.87) in the anchor-based method (P < 0.001). The percentage of patients achieving MCID at 7 weeks, 3 months, 6 months, and 1 year were 37-42 %, 57-62 %, 80-84 %, and 95-87 %, respectively.
CONCLUSIONS: This study identified MCID values for PROMIS PF scores in the tibial plateau fracture population. Both MCID scores were similar, resulting in a reliable value for future studies and clinical decision-making. An MCID of 3.93 to 4.85 can be used as a clinical and investigative standard for patients with operative tibial plateau fractures.

摘要：
背景：了解患者报告结果测量中的最小临床重要差异（MCID）对于改善患者护理非常重要。这项研究的目的是确定接受胫骨平台骨折手术固定的患者的患者报告结果测量系统（PROMIS）身体功能（PF）域的MCID。
方法：所有在单个1级创伤中心接受手术固定的胫骨平台骨折患者均按当前程序术语代码进行鉴定。术后两个时间点没有PROMISPF评分或锚定问题的患者被排除在外。计算基于锚点和基于分布的MCID。
结果：PROMISPF得分的MCID在基于分布的方法中为4.85，在基于锚的方法中为3.93（SD14.01）。与无改善组7.02（SD9.87）相比，改善组10.95（SD9.95）到术后第二时间（<78周）的评分在基于锚的方法（P<0.001）中的改善明显更多。7周时达到MCID的患者百分比，3个月,6个月,一年为37-42%，57-62%，80-84%，95-87%,分别。
结论：本研究确定了胫骨平台骨折人群中PROMISPF评分的MCID值。两个MCID得分相似，为未来的研究和临床决策提供了可靠的价值。3.93至4.85的MCID可用作胫骨平台手术骨折患者的临床和研究标准。
