Clinically important change in the visual analog scale after adequate pain control.
OBJECTIVES To define the minimum clinically important difference (MCID) for the visual analog scale (VAS) of pain severity by measuring the change in VAS associated with adequate pain control. METHODS The authors conducted a prospective, observational study. Adult emergency department (ED) patients with acute pain (<72 hours) were eligible. Patients rated their pain severity on a 100-mm VAS o...
متن کاملEstimation of minimal clinically important difference in EQ-5D visual analog scale score after pulmonary rehabilitation in subjects with COPD.
BACKGROUND The effect of pulmonary rehabilitation (PR) on the EuroQol Group's 5-dimension questionnaire (EQ-5D) in COPD has been poorly investigated. In addition, conflicting results were reported about the visual analog scale component of EQ-5D (EQ-VAS). The purpose of this study was to evaluate the responsiveness of EQ-VAS to PR and its relationship with clinical and functional parameters in ...
متن کاملThe Pain Visual Analog Scale: Linear or Nonlinear?
To the Editor:—I have spent some time considering the conclusions reached by Aubrun et al. in their study investigating the relationship between the pain visual analogue scale (VAS) and morphine requirements in the postanesthesia care unit. They demonstrated that the Hill equation could be used to derive a sigmoid relationship between the pain VAS and morphine dosage, and concluded that this re...

متن کاملThe pain visual analog scale: is it linear or nonlinear?
UNLABELLED The visual analog scale (VAS) is a tool widely used to measure pain, yet controversy surrounds whether the VAS score is ratio or ordinal data. We studied 52 postoperative patients and measured their pain intensity using the VAS. We then asked them to consider different amounts of pain (conceptually twice as much and then half as much) and asked them to repeat their VAS rating after e...
