title: [Comparative analysis of efficiency of the estimation of quality of life in patients with irritable bowel syndrome using questionnaires IBS-QOL and index BEST].
abstract: OBJECTIVE
  To examine the power of correlation between IBS-QOL Questionnare and BEST index in patients with irritable bowel syndrome.
  
  
  METHODS
  The IBS-QOL and BEST index were administered to 71 patients with IBS twice: before and after treatment. Statistical analysis to test the correlation between IBS-QOL and BEST index was performed using Spearman's rho coefficient.
  
  
  RESULTS
  The study cohort included 71 patients with Rome-III IBS evaluated at the State Research Institute of Nutrition of Russian Academy of Medical Sciences (mean age 41,4; mean IBS-QOL = 65,6; 76% women). The mean completion + scoring time for BEST was under 3 minutes vs 25 minutes for IBS-QOL. There was a striking correlation (r = - 0,8) between BEST and IBS-QOL results.
  
  
  CONCLUSIONS
  BEST is a concise, rapidly completed, point-of-care IBS severity index that demonstrates large correlation with well-validated instrument for assessing QOL (IBS-QOL) in IBS patients.
