Various instruments are available to measure clinical outcomes in pediatric inflammatory bowel disease (Table 39.3). Valid pediatric clinical indices and quality of life measures exist for both UC and CD. Endoscopic scores, however, have not yet been evaluated in children. The evaluation of health related indices is an ongoing process and therefore, the development of new indices and the re-evaluation of the performance of existing indices will continue to be explored in different clinical and research settings.
