AB  - There are no reliable, valid, and responsive scales to measure the quality of 
      sedation in adult critically ill patients. Our objective was to develop a 
      summated rating scale with these properties and to define the minimal clinically 
      important difference (MCID). We developed and tested the scale in an 18-bed 
      medical-surgical intensive care unit (ICU) (12-bed acute and 6-bed subacute 
      unit). Following identification of relevant domains and item derivation, 116 
      observations were made on 38 patients; psychometric properties and interrater 
      reliability were assessed to allow item reduction. The final scale consisted of 
      two five-item subscales quantifying calmness and interaction along a continuum 
      from 5 to 30 points. Interrater reliability was 0.89 and 0.90; internal 
      consistency was 0. 95 for both subscales. To test construct validity, MCID, and 
      responsiveness 302 observations were made on 54 patients. Construct validity: 
      calmness score vs. need for further intervention to make the patient calm (R = 
      -0.82, P < 0.001); interaction score discriminated between acute vs. subacute 
      units, mean scores 15.28 +/- 8.26 vs. 23.54 +/- 7.42, mean difference 8.27 (95% 
      CI - 10.32 to -6.22); MCID - 2.2 and 2.5 for the calmness and interaction 
      subscales; Guyatt's responsiveness statistics - 1.4 and 2.3. The Vancouver 
      Interaction and Calmness Scale (VICS) is reliable, valid, and responsive.
