AB  - OBJECTIVE: The goal of this study was to determine the minimal change in pain 
      score recognized by patients as meaningful known as minimal clinically important 
      difference (MCID). METHODS: Pain was recordedupon admission, 30 and 60 min later 
      and patients were asked todescribe the extent of pain change on a 5-point Likert 
      scale ranging from "much better" to "much worse". Patients reported their pain by 
      two common pain scales comprising numeric rating scale (NRS) and visual analog 
      scale (VAS). We used receiver operating characteristiccurve to assess the 
      accuracy of pain scales. We then calculated the mean change in pain scores among 
      patients who reported their pain change as "a little better" or "a little worse" 
      and also analyzed regression to evaluate the MCID. RESULTS: A total of 150 
      patients and 253 pain changes were recruited. The MCID +/- SD (95% CI) was 
      1.65 +/- 1.58 (1.32-1.97) for NRS and 16.55 +/- 17.53 (12.96-20.15) for VAS. The area 
      under the curve by NRS and VAS were 0.86 and 0.89. For linear regression, the 
      line slope and the y-intercept were 17.56 and 1.88, for VAS; these values were 
      1.73 and 0.31 for NRS, respectively. CONCLUSIONS: Recognizing the extent of 
      change in pain score that really matters to patients is crucial for the 
      evaluation of treatment effect. Patients perceived a change of 1.65 points on NRS 
      and 16.55 on VAS in their pain severity as meaningful. This value was not 
      different whether the pain was perceived alleviated or aggravated.
