      minimal clinically important difference.

AB  - PURPOSE: The minimal clinically important difference (MCID) of the Appearance 
      domain of the SRS-22 questionnaire is an increase >/=1.0 in surgically treated 
      patients with adolescent idiopathic scoliosis (AIS). However, no study has sought 
      to identify the factors associated with an SRS-22 Appearance score increase 
      greater than the MCID at 2 years. METHODS: A retrospective analysis was performed 
      on a prospectively collected multicenter database of 1020 surgically treated AIS 
      patients with a minimum 2-year follow-up. Patients were divided into two cohorts: 
      "I" = Improved after surgery (Delta Appearance >/=1.0) and "NI" = Not improved after 
      surgery (Delta Appearance <1.0). Univariate regression was used to find a significant 
      difference between the cohorts for individual measures. Multivariate logistic 
      regression was used to find continuous predictors. RESULTS: 663 (65%) patients 
      were improved greater than the MCID, and 357 were not improved (35%). The 
      improved cohort trended toward a greater percentage of underweight patients 
      (p = 0.074) with lower preoperative SRS Appearance scores (p < 0.001) and larger 
      preoperative trunk shifts (p = 0.033). Postoperatively, those patients with 
      greater percent correction of thoracic (p = 0.021) and lumbar (p = 0.003) Cobb 
      angles, smaller apical lumbar translation (p = 0.006), and a greater correction 
      in trunk shift (p = 0.003) were most likely to attain the MCID. CONCLUSION: 
      Several factors influence which patients are most likely to attain the MCID 
      following surgery for AIS. Factors such as preoperative appearance scores and 
      body weight are patient specific; other factors such as percent correction of the 
      thoracic and lumbar Cobb angles, trunk shift, and lumbar apical translation may 
      be influenced by the surgeon. LEVEL OF EVIDENCE: II.
