allow one to compare the change in PRO scores following surgery with another external anchor measurement such as patient-perceived improvement following surgery or patient satisfaction with surgery. The literature contains multiple anchor-based calculation methods, which has resulted in substantial variability in reported MCID values. 6 , 7 , 19 , 21 , 27 Thus, definitive MCID values for the commonly used PRO questionnaires used in spine surgery have yet to be established.

surgical interventions and changes in disease trajectory. More importantly, PROs are more frequently incorporated in clinical trials as the primary outcome comparing health interventions for chronic diseases. 26 , 27 However, a challenge to interpreting the meaning of improvement in PROs is that the extent of change in a numerical score lacks a direct meaning or clinical significance. 14 The concept of minimum clinically important difference (MCID) has been put forth as the smallest improvement in the PRO needed to achieve a level of clinical improvement. In other

, and gait dysfunction. 29 Patients with DCM may have substantial functional impairment, significantly reduced quality of life, and be unable to perform certain activities of daily living. Surgery is typically recommended as the preferred management strategy for patients with clinical and imaging evidence of DCM. 5 , 8 In general, surgical decompression of the cervical spine is effective at halting neurological deterioration, relieving certain symptoms, and improving functional status and quality of life. The minimum clinically important difference (MCID) is

P atient - reported outcome questionnaires have become the standard measure for treatment effectiveness following spinal surgery. The VAS, 10 ODI, 8 , 9 , 22 SF-36, 27 and EQ-5D health survey 1 , 15 , 19 are the most commonly used PRO questionnaires for back and leg pain. A shortcoming is that the numerical scores of these outcome metrics alone lack a direct, clinically significant meaning. Because of this, the concept of a minimum clinically important difference or MCID has been developed as a means to measure the critical threshold of improvement

again given the experienced outcome). Unfortunately, multiple anchors have been used and several anchor-based MCID calculation methods have been described, resulting in substantial variability in MCID values. 24 Because of this variability, there has been no consensus on the best MCID calculation method; therefore, definitive MCID values have yet to be established for the aforementioned common PRO questionnaires used in spine surgery. Minimum clinically important difference values are specific to the PRO metric being used, the spinal pathology, and the surgical

with ASDs above these thresholds preoperatively have worse health-related quality of life (HRQOL) scores, and a change in the Scoliosis Research Society-Schwab classification score predicts these HRQOL outcomes. 34 However, information is lacking about whether meeting these thresholds after a 3CO has an impact on HRQOL. Furthermore, to increase the clinical applicability of the established HRQOL measures, minimum clinically important difference (MCID) and substantial clinical benefit (SCB) values have been established. 9 , 10 , 12 However, there is a paucity of

Index (ODI) 19 , 20 and the EQ-5D, 21 to assess treatment effects. Unfortunately, statistically significant changes in numerical scores for these assessment tools may not represent clinically meaningful differences. Thus, the determination of minimum clinically important differences (MCIDs), defined as the smallest change important to patients, is integral in the evaluations of and justifications for particular interventions. 22 Thresholds for MCID likely vary based on treatment, pathology, and patient characteristics. Although MCID thresholds have been broadly
