Woo DH, et al. - Between January 2010 and December 2015, researchers retrospectively reviewed the medical records of seven hundred eighty-four inflammatory bowel disease (IBD) patients visiting the IBD clinic in order to investigate the frequency, predictors, and clinical outcomes of these patients who were lost to follow-up in outpatient clinics. In this analysis, two hundred eighty-five newly diagnosed IBD patients who were followed up for at least 12 months were involved. It was observed in the findings that follow-up loss rate for IBD patients in remission state was 14.7%, and the predictors were far from the hospital and low C-reactive protein levels. Clinicians need to try to encourage patients to keep their adherence because most of follow-up loss patients experienced flare-up.
