Background: The Global Rating Scale is an endoscopy quality assurance programme, successfully implemented in England. It remains uncertain whether it is applicable in another health care setting. Aim: To assess the applicability of the Global Rating Scale as benchmark tool in an international context. Methods: Eleven Dutch endoscopy departments were included for a Global Rating Scale-census, performed as a cross-sectional evaluation, July 2010. Two Global Rating Scale-dimensions - 'clinical quality' and 'patient experience' - were assessed across six items using a range of levels: from level-D (basic) to level-A (excellent). Construct validity was assessed by comparing department-specific colonoscopy audit data to GRS-levels. Results: For 'clinical quality', variable scores were achieved in items 'safety' (9% = B, 27% = C, 64% = D) and 'communication' (46% = A, 18% = C, 36% = D). All departments achieved a basic score in 'quality' (100% = D). For 'patient experience', variable scores were achieved in 'timeliness' (18%=A, 9%=B, 73%=D) and 'booking-choice' (36%=B, 46%=C, 18%=D). All departments achieved basic scores in 'equality' (100%=D). Departments obtaining level-C or above in 'information', 'comfort', 'communication', 'timeliness' and 'aftercare', achieved significantly better audit outcomes compared to those obtaining level-D (p<0.05). Conclusion: The Global Rating Scale is appropriate to use outside England. There was significant variance. across departments in dimensions. Most Global Rating Scale-levels were in line with departments' audit outcomes, indicating construct validity. (C) 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.
